Definitions
- the invention relates to a stacked disk cooler, 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 reinforced shape in the area where the stack rests, so that the base plate has greater strength for a given material thickness or can be manufactured cost-effectively from a thinner material for given strength requirements.
- the base plate has at least one fastening section protruding beyond the outline for fixing the stacked-plate cooler to a structure.
- a fastening section can be, for example, a pierced tab for inserting a screw or the like.
- the attachment of the stacked plate cooler via the attachment means of the base plate can introduce bending moments into the base plate, so that the stiffening of the base plate according to the invention is particularly advantageous.
- the edge is designed as a bead that is curved in the direction of the stack.
- a bead in the context of the invention is any bulge of the base plate with a limited diameter, the crest of which protrudes beyond a surface of the base plate on one side and undercuts the surface of the base plate on the opposite side.
- the bead completely surrounds the outline of the stack, which enables particularly good support of the entire edge of the stack.
- the bead only partially runs around the outline of the stack, with an interruption of the bead in the area of a fluid connection being provided in a preferred detail design.
- the base plate can be designed to be particularly flat and unaffected by the bead-like formation, particularly in the area of fluid connections. This can be desired, for example, for the connection of the base plate to an internal combustion engine, to a transmission or to a filter module using sealing means such as O-rings or other seals.
- the bead can be introduced into the base plate in any desired manner, with the processes of embossing and/or deep-drawing of the base plate being preferred in the interest of cost-effective and precise mass production.
- the base plate rests directly on the stack of exchanger disks.
- a bent-up edge of a lowermost exchanger disk bears at least in sections on the edge of the base plate and is soldered to the edge.
- the stack is particularly well stiffened and in particular the lowest exchanger disk is reinforced by its soldered contact with the edge.
- a special reinforcing disc in particular a reinforcing disc of greater material thickness than the other exchanger discs, between the stack and the base plate can be dispensed with.
- Such reinforcing disks have hitherto been customary in stacked disk coolers according to the prior art, since an edge region of the lowest exchanger disk that is not duplicated or supported by a subsequent disk could represent a weak point in the stack.
- a stiffening plate is soldered flat to the base plate.
- a stiffening plate can be used, for example, to form a particularly flat sealing surface for the sealing attachment of the stacked-plate cooler to a flange, for example of an internal combustion engine.
- the stiffening plate is particularly preferably arranged on an opposite side of the base plate with respect to the stack.
- the base plate can be made sufficiently thin in the interest of shaping the edge, with a particularly dimensionally stable base plate unit being created in connection with the brazed reinforcement plate.
- a stacked disk cooler in this case an oil cooler for flange mounting on an internal combustion engine, on a transmission or a filter module, according to the prior art.
- a plurality of exchanger disks 1 are arranged one above the other to form a stack and are soldered to one another in a fluid-tight manner by means of raised edges 1a.
- the exchanger disks 1 have a material thickness of typically between 0.3 mm and 0.8 mm and in the present case have a total of 4 overlapping openings 1b provided in the corner areas, which in the stacked arrangement form fluid channels for oil and cooling water to flow through.
- the exchanger disks 1 have embossed structures 1c for generating turbulence in the fluids flowing through.
- turbulence inserts can also be provided between the exchanger disks in a known manner.
- the stack of exchanger disks 1 is arranged on a reinforcing disk 2 which in turn is soldered over its entire surface to a flat base plate 3 .
- the reinforcement disk 2 has a greater material thickness than the exchanger disks 1, typically around 0.3 mm to 2 mm. Its bent-up edge 2a is soldered all the way around to the edge of the bottom exchanger disk 1, so that the edge of the stack is not weakened in the area of the bottom exchanger disk.
- the reinforcement plate 2 (prior art, 1 ) is not required to connect the stack of exchanger disks 1 according to the prior art to the base plate 3 according to the invention.
- the base plate 3 is made from a flat sheet of aluminum, with a peripheral closed edge 4 being provided in the form of a bead that is arched in the direction of the stack.
- the edge or the bead 4 follows the outline of the stack of exchanger disks 1, so that the bent edge 1a of the bottom exchanger disk 1 rests against the edge of the arched bead 4 of the base plate 3 and is soldered.
- the base plate 3 has a total of 4 openings 5, which are aligned with the fluid channels of the openings 1b of the exchanger disks. According to the invention, it is not necessary for the base plate 3 to have openings for the passage of fluid. In particular, depending on the design of a stacked plate cooler according to the invention, between zero and four openings for fluid channels can be provided. For example, the in 4 shown stacked disc cooler with a modification of the base plate 2 provided in which only three openings for connecting fluid must be present in the base plate, the fourth connection 5 'in an upper end plate 6 of the stack of exchanger disks 1 is provided. If the stacked disk cooler is designed to be flanged to a structure such as an internal combustion engine, a transmission or a filter module, then there is expediently at least one opening 5 .
- the lowermost exchanger disk 1 lies with its erected edge 1a directly on the bead 4 of the base plate 3 and is soldered to it.
- the bead 4 thus directly forms a reinforcement of the lowermost exchanger disk in its edge area, so that the reinforcement disk 2 according to the prior art can be dispensed with.
- All of the exchanger disks in the stack can therefore have the same small material thickness.
- An exception to this may be the upper closing plate 6 of the stack, which is not included in the stack of exchanger disks 1 in the context of the invention.
- the height sh of the bead 4 is advantageously in the range between 1 and 6 mm.
- the base plate 2 shows a modification of the base plate 2 , in which the bead 4 does not completely encircle the outline of the stack. Rather, an interruption in the bead 4 is provided in a region 7 in the vicinity of an opening 5 in the base plate 3 .
- the base plate on its underside (see 7 ) be particularly flat in area 7, area 7 being provided as a sealing surface for interaction with a seal, for example an O-ring seal or surface seal.
- the stacked-plate cooler is screwed to a flange of an internal combustion engine, a transmission or a filter module by means of the underside of the base plate 3, for which purpose the base plate 3 has several fastening sections 8 with screw holes 8a that project beyond the outline of the exchanger plate stack.
- a stiffening plate 9 is soldered flat to the base plate 3 opposite the stack 1 .
- the shape of the base plate 3 essentially corresponds to that of the base plate 2 .
- the material thickness can be kept relatively small and thus the formation of the bead 4, for example by embossing or deep-drawing, is particularly simple.
- relatively low demands are made.
- the stiffening plate 9 is soldered flat to the base plate 3, with the underside of the stiffening plate forming a flat sealing surface for flanging on the stacked-plate cooler. It is noted that the stiffening plate 9 completely follows the contour of the base plate 3, so that the attachment portions 8 are formed on both plates 3,9.
- FIG. 9 shows another embodiment of the invention, in which the bead 4 in the base plate 3 is not as in the examples Figures 2 to 8 is produced by deep drawing, but by embossing the base plate 3.
- a groove 4a is embossed on the underside of the base plate 3, which forms a protruding edge 4b on the upper side of the base plate 3.
- a flank 4c of the edge 4b facing the stack of exchanger disks 1 is formed in an inclined manner in order to enable soldering to the bent-up edge 1a of the lowest exchanger disk 1 that is as flat as possible.
- 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 for all of the exemplary embodiments described above. In this case, for example, the plate 9 can also be made thinner, for example 0.3 to 6 mm.
