Definitions

  • the invention relates to a plate heat exchanger with a plurality of plates stacked one above the other, each of which alternately spanning a first and a second flow space for a first or second medium, wherein each plate has a peripheral edge and is designed substantially trough-shaped and wherein two adjacent plates each over the circumferential edges are connected to each other, and wherein an end plate is fixedly connected to at least one adjacent plate at least one end of the stack fixed to an end plate, wherein the peripheral edge of the adjacent plate over a parallel to this edge formed wall surface on the end plate and with this wall surface is firmly connected.
  • EP 0 623 798 A2 describes a plate heat exchanger with stacked trough-shaped heat exchanger plates, whose circumferential edges bear against one another and are soldered tightly to one another, all heat exchanger plates having the same shape.
  • the lowermost of the trough-shaped plates attached to the end plate is the weakest member in terms of strength.
  • the notch formed in the usual construction between the lower trough-shaped plate and the end plate is unfavorable in terms of force introduction and strength.
  • Oil coolers of this type are generally attached to the end plate by means of screws on the engine block or on modules close to the engine, and are therefore subjected to high lateral acceleration forces due to the engine vibrations during operation of the engine.
  • a usually even more critical load results from the pulsating oil pressure of the lubrication system. This acts on the one hand from the inside in the individual oil layers and on the other hand from below on the connection plate.
  • the opposite module or the motor housing is usually carried out at the interface with longer, open oil guide channels, which are closed by means of a contour seal and the heat exchanger end plate. Due to the bias of the seal and in particular by the swelling oil pressure in the connection channels, the heat exchanger connection plate is loaded on bending.
  • Plate heat exchangers of the type mentioned usually do not withstand such loads, the mentioned notch is often the starting point of cracks in the bottom plate oil or in the soldering. The result is leakage and media loss.
  • a plate heat exchanger for a motor vehicle engine which consists of several trough-shaped plates which are stacked and soldered to form adjacent hollow chambers with their upstanding edges at a distance, wherein the lowermost plate attached to an end plate is.
  • a reinforcing plate provided with a rim bordering the bottom plate. The reinforcement plate is soldered to the bottom plate.
  • WO 2007/038871 A1 describes a plate heat exchanger with an end plate and a stack of trough-shaped plates, wherein the lowermost plate rests flat against the end plate.
  • the bottom plate is surrounded by a circumferential stiffening frame.
  • the end plate designed as a sheet-metal punched part is usually dimensioned correspondingly larger, which, however, increases the space requirement, the weight and the costs.
  • the object of the invention is to meet the requirements in terms of strength in a plate heat exchanger of the type mentioned, without increasing the overall height or material use significantly.
  • the end plate consists of an aluminum alloy, wherein preferably the wall surface between two substantially planar, parallel surfaces of the end plate is formed.
  • the wall surface may be formed by an inner circumferential surface of a substantially trough-like receiving the end plate for the adjacent plate. It is particularly advantageous if the end plate forms a mounting plate of the plate heat exchanger. Parts can be saved, if the receptacle is at least partially formed by a molded recess in the end plate.
  • the end plate consists of a substantially flat plate member and a frame part preferably inseparably connected to the frame part, wherein the receptacle may be at least partially formed by the frame part.
  • the depth of the receptacle should substantially correspond at least to the height of the edge of the adjacent plate.
  • the wall surface is formed by an outer circumferential surface of the end plate. It is particularly advantageous if the end plate forms a cover plate of the plate heat exchanger.
  • the adjacent plate contacts the end plate at least predominantly with the end plate facing surface, wherein preferably the end plate is soldered to the adjacent plate.
  • openings such as inlet or outlet openings for the first or second coolant poured.
  • FIG. 1 shows a plate heat exchanger according to the invention in an oblique view in a first embodiment
  • Fig. 2 shows the plate heat exchanger in a section along the line H-II in Fig. 1
  • Fig. 3 an end plate of this 4 shows this end plate in an oblique view from below
  • FIG. 5 shows a plate heat exchanger according to the invention in an oblique view in a second embodiment
  • FIG. 6 shows the plate heat exchanger in a section along the line VI-VI in FIG. 5 7 shows a frame part of this plate heat exchanger in an oblique view from above
  • FIG. 8 shows this frame part in an oblique view from below
  • FIG. 9 shows a plate heat exchanger according to the invention in an oblique view in a third embodiment

  • FIG. 1 and 2 show a plate heat exchanger 1 with a number of stacked trough-shaped plates 2, wherein between the two adjacent plates 2 each have a flow space 3 is formed for a first or second medium.
  • the edges 4 each two adjacent plates 2 are soldered together.
  • an end plate 7 made of an aluminum alloy is arranged in the region of the side 6 facing away from the edge 4.
  • the end plate 7 is fixedly connected to at least one adjacent plate 2 at the lower end 14 stack 5 fixed to an end plate 7, wherein the peripheral edge 4 of the adjacent plate 2 supported on a parallel to this edge 4 formed wall surface 19 of the end plate 7 and this wall surface 19 is firmly connected.
  • the wall surface 19 is in this case formed between flat, parallel surfaces 7 'of the end plate 7.
  • the wall surface 19 is formed by an inner circumferential surface 16 of a substantially trough-like receptacle 17 of the end plate 7 for the adjacent plate 2 is formed, wherein the receptacle 17 is designed as a recess 18 formed in the end plate 7, which has substantially the shape of the bottom plate 2.
  • the end plate 7 with the recess 8 can be made, for example, by a thixocasting method
  • the recess 8 substantially corresponds at least to the height h of the edge 4 of a plate 2.
  • the bottom plate 2 is completely taken up by the recess 8, wherein the end plate 7 facing surface 2a of the plate. 2 over the entire surface of the end plate 7 rests. In this case, the entire surface 2a of the plate 2 is soldered to the end plate 7.
  • openings 9 for the inflow or outflow of the cooling media are formed in the end plate 7.
  • the strength of the plate heat exchanger 1 can be sufficiently increased by means of the end plate 7 made of an aluminum alloy produced, for example, by the thixocasting process, without having to accept significant disadvantages in terms of height and weight.
  • the end plate 7 consists of a substantially flat plate part 7a formed by a punching plate and a frame part 7b connected inseparably therewith, wherein the frame part 7b forms an additional reinforcement comprising the heat exchanger block.
  • the frame part 7b is formed with one of the above-mentioned manufacturing methods, so that a similar body as in the embodiment 1 in FIGS. 1 to 4 is produced.
  • the frame part 7b forms a receptacle 17 for the adjacent plate 2, wherein a wall surface 19 formed by an inner circumferential surface 16 of the frame part 7b supports the edge 4 of the adjacent plate 2.
  • the flat plate member 7a formed by a sheet metal plate may have solder plating, it is possible to directly solder a turbulence insert 10 thereon. This saves a disk.
  • the end plate 7 in each case forms a mounting plate 12 having mounting openings 11.
  • FIGS. 9 to 14 show plate heat exchangers 1 in which the end plate 7 forms a cover plate 13.
  • the cover plate 13 must also withstand oil pressure and vibration or burden the remaining plate structure of the plate heat exchanger 1 least possible.
