Definitions

  • the invention relates to a plate heat exchanger with the features from the preamble of claim 1.
  • the plate heat exchanger described in the preamble is known from international patent application WO 98/59208.
  • the planes of the inlet cross section and the outlet cross section are parallel to the plane of the cover plate in this known connecting piece. As a result, there is no angle between the two cross-sectional planes, or its number of angular degrees is zero.
  • it is difficult to connect a connecting line made of metal to the connecting piece without losing the compactness of the arrangement.
  • compact arrangements often have to be made because the installation space offered, for example, in the engine compartment of a motor vehicle is very limited.
  • the "case-less" plate heat exchanger known from EP 893 667 B1 which also belongs to the type of plate heat exchanger mentioned here, has inlet or outlet connections arranged on the cover plate, which protrude perpendicularly to the body of the plate heat exchanger. In other words, there is a right angle between the plane of the inlet cross section and the plane of the outlet cross section of the connecting piece.
  • the object of the invention is to expand the possible uses of housing-free plate heat exchangers.
  • a plate heat exchanger according to the preamble of claim 1 according to the invention by its characterizing features. Because the inlet cross-section and the outlet cross-section of the connecting piece are arranged at an acute angle to each other and a line end opening into the inlet or outlet cross-section runs at least partially above the cover plate, the possible uses of such plate heat exchangers have been improved or expanded, because they can now also be used in very small installation spaces can be installed. If there are several such connecting pieces, a corresponding line end is assigned to each connecting piece. In this case, by definition, acute angles should include those angles whose number of degrees is greater than 0 and less than 90 °, the larger angle being able to be as large as is possible with the technical means of deep-drawing the plate.
  • the invention is an angled connecting piece, which at first glance may seem very common.
  • this connecting piece is made from an approximately flat plate, usually from the cover plate of the plate heat exchanger, by deep drawing, which poses some manufacturing problems.
  • the expert would rather resort to elbow connectors and attach and solder them as an individual part on the cover plate, which is a disadvantage.
  • the applicant agrees with this view as long as she is not aware of such an elbow connector drawn from a plate in connection with plate heat exchangers.
  • the plate heat exchanger has additional features which are specified in the subclaims and which can be expected to have additional advantageous effects.
  • the auxiliary bearing provided between the line end and the cover plate which is very advantageous for certain spatial installation constraints, leads to a very stable fastening of a line to the plate heat exchanger, which is particularly suitable for use in motor compartments of motor vehicles.
  • the plate heat exchanger has a vent for the cooling circuit to which it is connected. This is advantageous if the installation location of the plate heat exchanger is provided at a geodetically located point of the cooling circuit. Such a vent on the plate heat exchanger seems to be easier and less expensive to implement (but equally effective) than, for example, a vent valve which is arranged in a pipeline. Further features and advantages of the invention result from the following description of an exemplary embodiment. Fig.
  • FIG. 1 shows a perspective view of the plate heat exchanger and Fig. 2 shows a plan view of the same.
  • FIG. 3 shows the section AA drawn in FIG. 2 and
  • FIG. 4 shows the section BB from FIG. 2.
  • the plate heat exchanger shown is an oil cooler which is used in a motor vehicle to cool motor oil by means of the Coolant of the motor vehicle engine circulating in the cooling circuit is used. (Not shown)
  • connection piece 12 formed from the cover plate 10 and the line end 15 are connected to an inlet duct 5
  • the plane provided with the reference symbol 13 is a plane of the inlet cross section
  • with the reference symbol 14 is a plane of the outlet cross section which is on the Level of the cover plate 10 is, or parallel to it.
  • the inlet cross section 13 becomes the outlet cross section 14 , or vice versa.
  • a plurality of such connection pieces 12 with line ends 15 can also be present on a plate heat exchanger, although only a single one has been illustrated in the figures. In Fig.
  • the inlet channel 5 intended in the case shown for the cooling liquid was drawn in section.
  • the associated outlet channel 7 was shown in FIG. 2 only as a circle with dashed lines. The same applies to the inlet channel 6 and the outlet channel 8 , which are intended, for example, for the engine oil.
  • the inlet and outlet channels 5 , 6 , 7 , 8 pass vertically through the stack of heat exchanger plates 1 and 2 , for which purpose corresponding openings are present in the heat exchanger plates 1 and 2 .
  • Flow channels 3 and 4 are located between the heat exchanger plates 1 , 2 . As shown in FIG.
  • the inlet channel 5 (also the outlet channel 6, not shown) is connected to the flow channels 4 , so that the cooling liquid can flow from the inlet channel 5 via the flow channels 4 to the outlet channel 6 .
  • the flow channels 3 for the engine oil which are connected in the same way to the inlet channel 7 and the outlet channel 8 .
  • the connecting piece 12 was formed from the cover plate 10 in several production stages by deep drawing, the connecting opening 30 being formed in the connecting piece 12 in the last step.
  • the angle 20 between the plane of the inlet cross section 13 and the plane of the outlet cross section 14 is approximately 50 °.
  • the line end 15 was inserted into the mentioned connection opening 30 of the connection piece 12 .
  • the line end 15 surrounds the connection opening 30 from the outside, which then has a flange attachment.
  • the line end 15 has a bead, which is a stop to facilitate the insertion and subsequent sealing soldering.
  • the line end 15 also has a slight bend, so that it can extend in the immediate vicinity above the cover plate 10 , as a result of which the plate heat exchanger is generally very compact and space-saving, in particular has a low overall height, as indicated on the left edge of FIG. 3 has been.
  • the bend of the line end 15 can be dispensed with if the angle 20 between the entry plane 13 and the exit plane 14 approaches a right angle.
  • the line end 15 is arranged in such designs, not shown, in which a connecting piece 12 is located on the base plate 9 .
  • the auxiliary bearing 40 has a head 41 on which the line end 15 is fastened and a foot 42 with which it is soldered to the cover plate 10 .
  • there is a slight depression or the like on the foot 42 which cooperates with a corresponding elevation (knob) on the cover plate 10 .
  • the auxiliary bearing 40 can also be formed from the cover plate 10 by means of deep drawing and therefore does not represent an individual part. (not shown) However, as shown in FIG.
  • the connecting piece 12 is located directly above the inlet channel 5 or its vertical 25 .
  • the connecting piece 12 is arranged offset to the vertical 25 , but of course remains in hydraulic connection with the inlet channel 5 .
  • a vent 50 for the coolant circuit is located on the cover plate 10 .
  • the vent 50 has a sealing screw 51 . After loosening the sealing screw 51 , gas inclusions contained in the cooling liquid can escape, since the ventilation 50 is connected to the upper flow channel 4 for the cooling liquid via a bore or the like.
  • the plate heat exchanger has been mounted or soldered on a fastening plate 45 in order to fasten it to a motor housing, for example, by means of screws or similar fastening means, not shown, which are inserted through holes 46 .
