Definitions

  • the invention relates to a stacked plate radiator, in particular for an internal combustion engine, a transmission or a filter module, according to the preamble of claim 1.
  • the base plate Due to the raised edge along the outline of the stack, the base plate has a stiffening in the form of the system stack of the stack, so that the base plate for a given material thickness has a higher strength or can be made inexpensively for given strength requirements of a thinner material.
  • the base plate has at least one over the outline protruding mounting portion for fixing the Stapelaminkühlers to a structure.
  • a fixing portion may be, for example, a pierced tab for inserting a screw or the like.
  • the edge is designed as a convex beading in the direction of the stack.
  • a bead according to the invention is any groove-like limited in diameter bulge of the base plate to understand their vertices on one side over a surface of the base plate and undercuts the surface of the base plate on the opposite side.
  • the bead completely surrounds the outline of the stack, whereby a particularly good support of the entire edge of the stack is made possible.
  • the bead only partially circumscribes the outline of the stack, wherein in a preferred detailed design an interruption of the bead in the region of a fluid connection is provided.
  • the base plate can be formed particularly level and uninfluenced by the bead-like formation, in particular in the area of fluid connections. This may be desired, for example, for the connection of the base plate to an internal combustion engine, to a transmission or to a filter module via sealing means such as O-rings or other seals.
  • the bead can be introduced in any way in the base plate, the methods embossing and / or deep drawing of the base plate in the interest of cost-effective and accurate mass production are preferred.
  • the base plate rests directly on the stack of exchanger disks.
  • a bent-up edge of a lowermost exchanger disk rests against the edge of the base plate at least in sections and is soldered to the edge.
  • the stack is particularly well stiffened and in particular the bottom exchanger plate is reinforced by their soldered system at the edge.
  • a special reinforcing disk in particular a reinforcing disk of greater material thickness than the other exchanger disks, can be dispensed with between the stack and the baseplate.
  • Such reinforcing discs are heretofore common in prior art stacked disc radiators because one doubled by a subsequent disc or supported edge region of the lowermost exchanger disk could constitute a weak point of the stack.
  • a stiffening plate is soldered flat on the base plate.
  • a stiffening plate for example, a particularly flat sealing surface for sealing attachment of the stacked disc radiator to a flange, for example an internal combustion engine, may be formed.
  • the stiffening plate is particularly preferably arranged on an opposite side of the base plate relative to the stack. In particular, this can be achieved in that the base plate in the interest of the formation of the edge can be made sufficiently thin, in conjunction with the surface soldered stiffening plate creates a particularly dimensionally stable base plate unit.
  • Fig. 1 shows a Stapelumblenkühler, in this case an oil cooler for flanging to an internal combustion engine, to a transmission or a filter module, according to the prior art.
  • a plurality of exchanger disks 1 is arranged one above the other to form a stack and soldered to one another in a fluid-tight manner by means of erected edges 1a.
  • the exchanger disks 1 have a material thickness of typically between 0.3 mm and 0.8 mm and presently have a total of 4 provided in the corner regions, overlapping apertures 1 b, which form in the stacked arrangement fluid channels for flow with oil and cooling water.
  • the exchanger disks 1 have embossed structures 1c for generating turbulences of the fluids flowing through.
  • turbulence inserts can also be provided between the exchanger disks in a known manner.
  • the stack of exchanger discs 1 is arranged according to the prior art on a reinforcing plate 2, which in turn is soldered flat with a flat base plate 3.
  • the reinforcing disk 2 has a greater material thickness than the exchanger disks 1, typically about 0.3 mm to 2 mm.
  • Their bent-up edge 2a is soldered circumferentially to the edge of the lowermost exchanger disk 1, so that no edge-side weakening of the stack occurs in the region of the lowermost exchanger disk.
  • Fig. 2 shows the base plate of a first embodiment of the invention, the with the otherwise not shown stack of heat exchanger plates 1 according to the prior art according to Fig. 1 can be combined.
  • the reinforcing plate 2 (prior art, Fig. 1 ) is not required to connect the stack of heat exchanger disks 1 according to the prior art with the base plate 3 according to the invention.
  • the base plate 3 according to the first embodiment of the invention is made of a flat aluminum sheet, wherein a circumferential closed edge 4 is provided in the form of a bulging in the direction of the stack bead.
  • the edge or the bead 4 follows the outline of the stack of exchanger disks 1, so that the bent-up edge 1a of the lowermost exchanger disk 1 rests against the flank of the bulged bead 4 of the base plate 3 and is soldered.
  • the base plate 3 has in the present case a total of 4 openings 5, which are aligned with the fluid channels of the openings 1b of the exchanger plates.
  • the base plate 3 has openings for fluid passage.
  • between zero and four perforations may be provided for fluid passages.
  • the in Fig. 4 shown stack disc radiator with a modification of the base plate Fig. 2 provided, in which only three openings must be present for the connection of fluid in the base plate, wherein the fourth connection 5 'is provided in an upper end plate 6 of the stack of exchanger disks 1.
  • the stacked disc radiator is designed to be flanged to a structure such as an internal combustion engine, a transmission or a filter module, it is expedient to have at least one opening 5.
  • Fig. 5 shows, the lowermost exchanger plate 1 with its raised edge 1a directly to the bead 4 of the base plate 3 and is soldered to this.
  • the bead 4 immediately forms a reinforcement of the lowermost exchanger disk in its edge region, so that it is possible to dispense with the reinforcing disk 2 according to the prior art.
  • All of the exchanger disks of the stack can thus have the same low material thickness. Except where appropriate, this excludes the upper end plate 6 of the stack, which is not counted in the context of the invention to the stack of exchanger disks 1.
  • the height sh of the bead 4 in the range between 1 and 6 mm.
  • Fig. 6 shows a modification of the base plate Fig. 2 in which the bead 4 does not completely wrap around the outline of the stack. Rather, an interruption of the bead 4 is provided in a region 7 in the vicinity of an opening 5 of the base plate 3.
  • This allows the base plate on its underside (see Fig. 7 ) in the region 7 be particularly flat, wherein the region 7 is provided as a sealing surface for cooperation with a seal, for example O-ring seal or surface seal.
  • the stack disc radiator is screwed by means of the underside of the base plate 3 to a flange of an internal combustion engine, a gearbox or a filter module, to which the base plate 3 has a plurality of protruding over the outline of the exchanger disk stack mounting portions 8 with screw holes 8a.
  • Fig. 8 shows a further embodiment in which opposite to the stack 1, a stiffening plate 9 is soldered flat on the base plate 3.
  • the base plate 3 corresponds in shape essentially to the base plate according to FIG Fig. 2 , wherein the material thickness can be kept relatively low and thus the formation of the bead 4, for example by means of embossing or deep drawing, is particularly simple.
  • Regarding the flatness of the bottom of the Base plate 3 are made relatively low requirements.
  • the stiffening plate 9 is soldered flat with the base plate 3, wherein the underside of the stiffening plate forms a flat sealing surface for flanging the Stapelaminkühlers. It is noted that the stiffening plate 9 completely follows the outline of the base plate 3, so that the fixing portions 8 are formed on both plates 3, 9.
  • Fig. 9 shows a further embodiment of the invention, in which the bead 4 in the base plate 3 not as in the examples after Fig. 2 to Fig. 8 is produced by deep drawing, but by embossing the base plate 3.
  • a groove 4a is impressed on the underside of the base plate 3, which forms a protruding edge 4b on the upper side of the base plate 3.
  • a stack of exchanger plates 1 facing edge 4c of the edge 4b is formed inclined, to allow the largest possible possible soldering with the bent edge 1 a of the lowermost exchanger plate 1.
  • the height h of the embossed protruding edge 4b above the plane of the base plate 3 is typically up to two-thirds of the material thickness s of the base plate 3.
  • material thicknesses s of the base plate 3 in the range between 2 mm and 8 mm are preferably provided.
  • the plate 9 may be made thinner, such as 0.3 to 6 mm.
