Definitions

  • the invention relates to a heat exchanger, particularly a cooler, e.g. Oil cooler, of the type defined in the preamble of claim 1.
  • a heat exchanger particularly a cooler, e.g. Oil cooler, of the type defined in the preamble of claim 1.
  • Heat exchangers of this type are known (WO 84/01208), in which the collectors consist of cylinder tubes and the partitions are designed as circular caps adapted to the inside diameter of the tubes, which are pushed into the tubes in the axial direction and connected to them by soldering.
  • These closure elements which are attached with their outer circumferential surface to the inner surface of the tube wall by soldering, have a large axial width.
  • Such is at least with regard to the outer peripheral surface due to the soldering attachment necessary so that a firm load-bearing connection can be made by soldering, because the surface of the end closure elements are under the pressure of the medium prevailing in the heat exchanger and are particularly large at high medium pressure Forces loaded that stress the soldering of the end closure elements above all on shear.
  • the contact surfaces must be of the end closure elements are dimensioned as large as possible, which, if the diameter is predetermined by that of the collector tubes and cannot be increased, must be realized by a correspondingly large dimension in the axial direction.
  • Such relatively wide end closure elements within the tubular collector mean that the latter are dimensioned correspondingly long and with correspondingly long end sections protrude on both sides beyond the area of the heat exchanger network. This not only requires more material but also leads to a larger space requirement for the heat exchanger. Manufacturing problems also arise; the end closure elements to be inserted into the tubes are difficult to position at the location, and this is reproducible, to which they are to be attached by soldering.
  • the axially inserted closure elements sit in each heat exchanger in the same place on the header tubes. If the soldering is to be carried out in a soldering bath or in a heat treatment furnace, the locking elements used in the axial direction of the header pipes for the transport of the assembled component and in the heat treatment furnace must be secured in their position in order to prevent them from slipping automatically. This also creates difficulties. The production proves to be difficult and complicated solely with regard to the end closure elements. Another disadvantage is that due to the medium pressure acting on the surface of the closure elements during operation of the heat exchanger, the end closure elements and, via this, the soldered connection are exposed to relatively large forces, and there is therefore a risk of shearing off and leaking.
  • the invention is based on the object of designing a heat exchanger, in particular a cooler, for example an oil cooler, of the type mentioned in the preamble of claim 1, that the closure elements can be introduced quickly and easily at the same reproducible location and can be designed to save space.
  • a heat exchanger in particular a cooler, for example an oil cooler, of the type defined in the preamble of claim 1 by the features in the characterizing part of claim 1.
  • a heat exchanger in particular a cooler, for example an oil cooler
  • relatively thin cross-sectional walls can be used which - viewed in the longitudinal direction of the respective collector - require little space, so that the collectors can be kept shorter in the area of the appropriately designed end closure element. This leads to material, cost and weight savings.
  • respective target positions for positioning and holding the partitions are specified.
  • the partitions are thus reproducibly positioned and fixed by the slots.
  • the slots form visible assembly points and also act as guides when inserting the partitions.
  • the partition walls themselves can be designed as thin slices, which are therefore simple and inexpensive.
  • the insertion of the partitions into the slots is also quick and easy and therefore inexpensive to do.
  • the slot width and the cross-sectional thickness of the partition can be dimensionally coordinated so that the partitions inserted into the slots are held in place after insertion, so that no additional securing means are required to hold the partitions in place, for example when transporting the Heat exchanger assembled from individual components in a soldering bath or a heat treatment furnace, in order to store all components there in one soldering process to connect by soldering.
  • each partition is held in a form-fitting manner in the slot and thus forces acting on the partition are thereby positively absorbed by the collector and a solder connection is relieved of these forces.
  • Another advantage is that the end regions of the collectors outside the end closure by means of the respective partition walls do not necessarily have to be accurate in shape and also do not have to end cleanly on the end face. The end sections projecting beyond the outer surface of the partition therefore do not require any special processing or attention.
  • a further advantage is that these end sections of the collectors projecting beyond the outer surface of the end partition walls are still freely available for other designs and tasks.
  • these end sections can be used to hold or secure the heat exchanger at the mounting location. Any connecting means can also be attached to these end regions, for example in order to connect other components to the heat exchanger or to connect the latter to other components.
  • the protruding end sections can also be used to form reference surfaces which always ensure a reproducible mounting of tubular collectors in the circumferential direction at the same place, which has advantages, for example, when assembling individual elements of the heat exchanger. This can be an advantage already in the production of the collectors.
  • the slots in the collectors required for the partitions to be used can be produced quickly and easily, for example simultaneously with the other slots in which the tubes of the heat exchanger network are received and fastened with their opposite ends.
  • the end sections of the collectors projecting beyond the outer surface of the end partitions can also be used, for example, for attaching side parts which each terminate the heat exchanger network at the side. Also for these end sections can be used advantageously for other purposes.
  • each collector at one end is closed by means of a conventional end stop plug as a closure element and the supply line for the medium or discharge of the medium takes place at the opposite end of the same collector.
  • FIGS. 1 to 4 show a first exemplary embodiment of a heat exchanger 10 which is designed in particular as a cooler, for example an oil cooler, water cooler or the like, but instead can also be in the form of a heat exchanger, condenser or the like.
  • the heat exchanger 10 has two approximately tubular collectors 11 and 12 which are arranged at a transverse distance from one another and, for example, run approximately parallel to one another. At least one of the collectors 11 and 12 consists of a round, for example circularly cylindrical tube.
  • both collectors 11 and 12 each consist of a circular cylindrical tube 13 or 14 with a cylindrical one Collector wall 15 or 16.
  • the collectors 11, 12 instead consist of oval tubes, flat tubes or the like.
  • Pipes 17 run between the collectors 11 and 12, which e.g. are formed as flat tubes, only the right tube 17a and left tube 17b in FIG. 1, which also forms the lateral closure, has a cross-sectional dimension that differs from the other tubes 17, in particular, as can be seen, is dimensioned larger in cross-section.
  • the tube 17a on the right in FIG. 1 can be used for the supply of a medium which is to be cooled in the design as a cooler and which is fed in the lower end region of the tube 17a, as illustrated by the arrow 18 there.
  • the pipe 17b running on the left in Fig. 1 can e.g. serve as a bridging line, which in certain operating states e.g. is opened by means of a valve, not shown, and connects the two collectors 11 and 12 by bridging the tubes 17.
  • All tubes 17, 17a and 17b are connected at their opposite ends to an associated collector 11, 12, so that the inside of the tubes 17, 17a, 17b is connected to the interior 19 and 20 of each collector 11, 12 and a medium, which is introduced, for example, in the region of the arrow 18 into the tube 17a on the right in FIG. 1 and above it is fed to the collector 11 arranged at the top in FIG. 1, as shown, or in another embodiment, not shown, instead instead multi-flow, the interior 19 of this collector 11, the interior of the tubes 17 or in the case of bridging operation of the tube 17b and the interior 20 of the header 12 can flow through, as shown in Fig. 1 by arrows.
  • the right tube 17a used here for feeding the medium is passed through and out of the collector 12 in the lower end region, so that the feeding according to arrow 18 can be carried out in a simple manner.
  • the interior 20 of the collector 12 is not connected to the interior of the tube 17a in this area.
  • the collectors 11 and 12 are closed as required in the area of one end or both ends by means of closure elements 21 and 22, respectively.
  • the upper collector 11 in FIG. 1 is closed in the area of both ends with a closure element 21, which has already been introduced in the area of the right end and has not yet been used for clarification in the area of the left end.
  • the lower collector 12 in FIG. 1 is likewise closed in the region of both ends by means of a closure element 22, the end on the right in FIG. 1 already being closed here, while the similar closure element 22 has not yet been introduced at the end on the left is shown. This provides a better overview.
  • each collector 11 or 12 in the region of both ends, as shown in FIG. 1, or in a modified form, for example only in the region of one end a respective closure element 21 or 22 is provided. If, for example, the supply of the medium is to take place at the upper right end of the collector 11 there in FIG. 1 and approximately coaxially to the tube, the closure element 21 is not required in this end region and instead the supply connection for the medium is there appropriate. Then the collector 11 is closed only at the left end in FIG. 1 by means of a closure element 21. The same procedure is followed with regard to the other collector 12 if, for example, the medium is to be discharged in the area of one end and approximately coaxially with the pipe run.
  • closure elements 21 and 22 in the first exemplary embodiment in FIG. 4 are all of the same design, which is why further details are explained below in particular with reference to FIGS. 3 and 4 and the closure element 22 there.
  • the respective closure element 21, 22 is formed from a partition 23, which is in particular designed as a disc.
  • the cross-sectional thickness of the partition 23, in particular the pane can roughly correspond to the cross-sectional thickness of the collector wall 15 or 16.
  • the cross section of the partition wall 23, in particular the pane does not have to be larger than that of the collector wall 15 or 16, but the cross section can, depending on the circumstances, be even smaller than that of the collector wall 15 or 16.
  • the respective partition 23, in particular a pane is fixed in the respective collector 11, 12 in particular by soldering, e.g. Soft soldering or brazing.
  • the respective partition 23, in particular a pane is in the respective collector 11 or 12 through a respectively assigned slot 25 in the collector 11 or slot 26 in the collector 12 in the collector 11 or 12 in the direction of the one on the left in FIG. 1 indicated arrows transversely to the longitudinal course of the collector 11, 12 inserted and fastened in this.
  • the respective partition wall 23, in particular the pane is thus introduced and is effective like a sword.
  • the respective slot 25 or 26 is located at a certain distance from the respective end of the collector 11 or 12, So that when the closure element 21 or 22 is inserted into the respective slot 25 or 26, in particular a disk-shaped partition 23, an end section 27 or 28 of the respective collector 11 or 12 protruding from there remains, which is connected to the interior 19 or 20 protrudes away from the outer surface of the partition 23, in particular the washer.
  • this protruding end section 27 or 28 can still be used in a variety of ways if so desired.
  • the respective end section 27 or 28 is in any case free and accessible for any desired design. For example, as illustrated in FIGS. 1 to 4, it can be unlatched in order to meet special requirements.
  • the notch creates, for example, reference surfaces that make it possible to reproducibly align the round tubular collectors 11, 12 in the circumferential direction with respect to any stop parts in relation to their longitudinal axis, for example for assembly, for assembly, etc.
  • the notches can also be used for other purposes to be useful.
  • Other configurations of the end sections 27, 28 are also possible. These can also be used, for example, for connecting other parts, for fastening the heat exchanger 10 or for attaching further parts to the latter, it being possible to intervene in the interior of each end section 27, 28, which is open towards the end, for example axially with appropriate means, and also transversely thereto , for example through slots, bores or the like, which are provided in the end section 27 or 28.
  • each collector 11 or 12 requires a very small space, measured in the axial direction of each collector 11, 12.
  • the length dimension of each collector 11, 12 therefore does not have to be chosen larger than in previously known designs in this form of end closure by means of the partition wall 23, in particular a washer, with the end sections 27, 28 being additionally added wins and the width of the heat exchanger network, measured from tube 17a to tube 17b, does not have to be reduced thereby.
  • each collector 11 or 12 has the further advantage that the ends of the collector 11, 12, which are spaced from the respective slot 25 or 26, do not have to be cut off and machined exactly , since such is not necessary for the tight end closure by means of the respective partition 23, which is inserted into the slot 25 or 26. This also simplifies production, which leads to a reduction in costs. It is also advantageous that the space at which the respective partition 23, in particular a pane, which closes the interior 19 or 20 is to be placed, is reproducibly predetermined by the slot 25 or 26. The slot 25 or 26 thus forms a desired position for the partition 23 and at the same time a guide for the approximately sword-like insertion of each partition 23, along which the partition 23 is guided into the correct place in the collector 11 or 12.
  • the respective target position for the closure elements 21, 22 of each collector 11 and 12 is thus reproducibly defined by the slots 25, 26 and the respective partition 23, in particular the disc.
  • the partition 23, in particular the washer which has been introduced in each case does not have to be particularly held and secured by means of aids or the like.
  • the respective slot 25, 26 passes through only a partial area of the collector wall 15 or 16 Embodiment for each partition 23 in the insertion direction of this only contain a slot 25 or 26 in the associated collector wall 15 or 16, unlike the third embodiment in Fig. 6, which will be discussed later.
  • the respective partition 23 is received with an edge area, which is illustrated in FIG. 4 with 29, in the respective slot 26 and is gripped on both sides. On its remaining edge region, which does not run in the respective slot 26, which is illustrated by 30 in FIG. 4, the end face of the partition wall 23 lies against the facing inner surface 32 of the collector wall 16.
  • the partition 23 e.g. is fixed by soldering in the collector 12, a firm and above all a tight connection can be achieved in the entire system area. Attachment by soldering can be carried out particularly easily, quickly and inexpensively when the parts to be soldered are solder-plated, which may also be the case for the respective partition walls 23, in particular disks.
  • Each dividing wall 23 is at least substantially matched with regard to the contour profile of the edge region 29 received in the slot 25, 26 to the contour profile there of the collector wall 16, in particular the outer surface thereof.
  • the outer circumferential surface of the edge region 29 of each partition 23 is then essentially flush with the outer surface of the collector wall 16. This is not essential.
  • the outer circumferential surface of the edge region 29, which is received in the slot 25, 26, can in one case or another extend deeper in relation to the outer surface of the collector wall 15, 16 or project beyond this outer surface.
  • Each partition 23, in particular a disc, is also adapted with respect to the contour of the other edge region 30 lying on the inside of the collector wall 16 to the contour of the inner surface 32 of the collector wall 15, 16 there, so that an approximately tight connection is established there as far as possible by positive locking.
  • each collector 11, 12 in accordance with the first exemplary embodiment in FIGS. 1 to 4 is formed from a tube 13 or 14 with a circular cylindrical cross section
  • the design of the slots 25, 26 and the respective partition wall 23, in particular a disk is special in adaptation thereto easy.
  • the respective partition 23, in particular a disk is round, in particular circular.
  • the slot 25, 26 in the collector 11 or 12 is then at least substantially semicircular.
  • the respective partition 23 then has a larger semicircular part 33 which extends above the respective half diameter and a smaller semicircular part 34 which extends below it.
  • the partition 23 can be inserted through the slot 25, 26 into the respective collector 11 or 12 in such a way that the smaller part 34 rests with its outer peripheral surface 31 of the edge region 30 on the inner surface 32 of the collector wall 15, 16 and the larger part 33 is held with its edge region 29 in the slot 25, 26.
  • the slots 25, 26 in the collector 11 and 12 are each made on the same side in the collector wall 15 and 16, in which the other, the facing ends of the tubes 17, 17a, 17b receiving slots are included, so that all slots including the slots 25, 26 in a clamping of the collector 11, 12 and from the same side, for example in one operation, can be introduced. This simplifies production and leads to time and cost savings. If any slots, notches or the like are desired in the region of the end sections 27 and 28, these can also be introduced in the same operation, which leads to a further simplification.
  • the collectors 11, 12 e.g. can also be obtained in each case from continuous long tubes which are provided as long parts at the desired location with the slots for inserting the tubes 17, 17a and 17b and the slots 25, 26, e.g. in each case where a separation to obtain the individual pipe sections for the collectors 11, 12 is to be carried out, the slots 25, 26 are provided with corresponding slots and are thus provided with target markings for separating the collectors 11, 12 from the long parts. These desired markings can be left after being cut to length, since they are located in the region of the end sections 27, 28 and are not disruptive there. You can e.g. similar to the notches visible at the end in FIG. 1.
  • the collector 112 shown has the shape of a tube 114 which has an angular, for example square, and in this case, for example square tube cross section with four collector walls 135 to 138, of which the mutually opposite collector walls 135 and 137 run parallel to one another and likewise the collector walls 136 and 138.
  • the at least one slot 126 is located in the upper collector wall 138 in FIG. 5 through which the slot 126 passes.
  • the width of the slot 126 corresponds to the distance that the inner surfaces 132 of the slot-free, opposing collector walls 135, 137 have from one another.
  • the respectively assigned partition 123 is also quadrangular, in particular rectangular, and can be inserted in the direction of the arrow like a sword into the square tube 114 through the slot 126.
  • the width of the partition 123 corresponds to the width of the slot 126, ie the distance between the inner surfaces of the collector walls 135, 137 from one another.
  • the height of the partition 123 measured in the direction of insertion according to the arrow is greater than the inner distance dimension of the collector wall 136 from the collector wall 138, namely by the cross-sectional thickness of the collector wall 138 larger than this inner distance dimension, so that when the partition wall 123 is inserted, it is rectilinear with an upper one extending edge area 129 is received within the slot 126 and gripped on both sides, while the remaining edge area 130, which extends over the three remaining sides of the partition 123, with its narrow surface facing the interior 120 of the tube 114 on the respective inner surface 132 of the collector walls 135 to 137 is present.
  • the partition 123 When the partition 123 is fastened by soldering, it is soldered to the pipe 114 in the area of these narrow surfaces lying inwards and in the area of the edge area 129, which is held in the slot 126 on both sides, so that a firm and also tight connection is produced.
  • the partition 23, 123 takes place in the collector 11, 12, 112 and the partition 23, 123 can absorb relatively large forces even without any other connection to the collector 11, 12 112 and can be passed on to the collector 11, 12, 112, which result in the medium under pressure from the pressure of the medium acting on the surface of the partition 23, 123. Due to this positive hold of the partition 23, 123, the soldered connection does not necessarily have to absorb these forces. The risk of a possible leak, which could otherwise be caused by this soldering in the end due to high pressure loads, is therefore eliminated.
  • the collector 212 likewise consists of a tube 214 with a square cross section.
  • a slot 226 corresponding to FIG. 5 is contained in the collector wall 238.
  • the collector walls 235 and 237 run approximately parallel to one another and have the same distance as in FIG. 5.

  • the width of the partition 223 corresponds to the distance between the inner surfaces of the two collector walls 235 and 237 from one another.
  • the height of the partition 223 measured in the insertion direction according to the arrow deviates from the exemplary embodiment in FIG. 5 but corresponds to the outside dimension, measured between the outside of the collector wall 236 and the collector wall 238, so that when the partition wall 223 is inserted, it is received with one edge area 229 in the area of the slot 226 and with a similar, opposite edge area 247 in the second slot 246.
  • the partition 223 used is positively held on both edge regions 229 and 247, which run at a distance from one another, so that an even better hold of the partition 223 is achieved solely by positive locking in the collector 212 and the soldering connection used for fastening even further from on Partition 223 acting forces is relieved. Due to the two slots 226 and 246 running in alignment within a transverse plane, the insertion position of the partition wall 223 is also specified more precisely and the insertion of the partition wall 223 is made even easier, because not only the slot 226 penetrated first forms a guide when inserted, but also the second slot 246, which specifies the target position for the other edge area 247.
  • the fourth exemplary embodiment in FIG. 7 differs from that in FIG. 5 solely in that the width of the slot 326 corresponds to the outer spacing of the collector walls 335 and 337 from one another.
  • the slot 326 thus also extends on both sides over the cross-sectional area of the collector wall 335 and 337.
  • the partition wall 323 on the edge area 329 received in the slot 326 has protruding shoulders 350 on both sides, which should also be received in the slot 326.
  • a second slot may also be required in the collector wall 336, in which case the partition wall 323 is dimensioned higher by the cross-sectional thickness of the collector wall 336, so that in inserted state of the partition 323 in FIG. 7 the lower edge area can then engage in a form-fitting manner in this second slot.
  • Slats made of a material with good thermal conductivity, e.g. made of aluminum, copper, brass or the like.
  • closure elements 21, 22 in the form of the partition walls 23 Individual or all of the described elements of the heat exchanger can be solder-plated, as a result of which the production is particularly simplified.
