Definitions

  • the present invention relates to a stacked plate heat exchanger according to the preamble of claim 1.
  • a heat exchanger is known from DE-A-102011078136 known.
  • the invention also relates to an internal combustion engine with such a stacked plate heat exchanger.
  • DE 10 2005 044 291 A1 is a generic stacked plate heat exchanger, in particular a charge air cooler, with a plurality of stacked and interconnected, in particular soldered, elongated discs known having a cavity for passing a medium to be cooled, for example, charge air, in the longitudinal direction of the discs and another cavity for performing of a coolant limit.
  • the discs each have an input port and an output port for the medium to be cooled.
  • At least one coolant connection partially extends around a connection for the medium to be cooled.
  • generic stack-top heat exchangers always have the problem that they are connected on one side over their base plate cantilevered example of an internal combustion engine, which due to the unilateral connection and the large Kragweite large vibrations on the base plate must be removed, making the base plates themselves comparatively difficult and thus have to be trained expensive.
  • the present invention therefore deals with the problem of providing for a stacked plate heat exchanger of the generic type an improved or at least one alternative embodiment, which allows in particular with regard to vibrations occurring improved connection.
  • This problem is solved according to the invention by the subject matter of the independent claim.
  • Advantageous embodiments are the subject of the dependent claims.
  • the present invention is based on the general idea not to store a stacked plate heat exchanger as previously known from the prior art, in the manner of a cantilever exclusively at one longitudinal end and thereby absorb large vibrations, but a storage on a distributor plate or .2 to realize two base plates, which is arranged centrally, in particular centrally of the stacked plate heat exchanger / are.
  • the stacked-plate heat exchanger according to the invention which may be designed, for example, as an intercooler of an internal combustion engine, has a first and a second stacking disk package, each with a plurality of stacked and interconnected, in particular soldered, stacking disks and a base plate, via which a supply and / or or a discharge of a coolant takes place.
  • the two stacking disk packages are connected directly via their base plates with each other and with a coolant inlet and / or a coolant outlet.
  • the holder of the stacked plate heat exchanger via a holder which is connected to the two centrally arranged base plates.
  • the first stacking disk pack is designed as a high-temperature cooler and the second stacking disk pack as a low-temperature cooler.
  • a charge air flow for an internal combustion engine can be effectively cooled by this is first passed through the designed as a high-temperature radiator stack stacking package, then through the base plate, and the base plate of the second stacking disk package and then designed as a low-temperature radiator second stacking disk package.
  • the stacked-plate heat exchanger according to the invention thus also a comparatively simple coupling of a high-temperature cooler with a low-temperature cooler is possible.
  • the first and the second stacking disk pack each have a cover disk with a passage for the medium to be cooled, in particular for exhaust gas to be cooled.
  • the stacked plate heat exchanger is orthogonally through the stacked disk planes to be cooled medium, which of course in the first stacking disk package and / or in the second stacking disk package, a deflection of the medium to be cooled, for example, to be cooled exhaust gas parallel to the respective stacking disks is possible.
  • the base plates formed of solderable aluminum. Aluminum has a comparatively high thermal conductivity coefficient and is also comparatively light, which makes it suitable for the use of a Charge air cooler in an internal combustion engine of a motor vehicle is particularly advantageous.
  • the present invention is further based on the general idea to use a previously described stacked plate heat exchanger as a charge air cooler in an internal combustion engine, which in particular a vibration-optimized connection of the stacked plate heat exchanger is made possible.
  • Fig. 1-3 has a stacked-plate heat exchanger 1 according to the invention, which may be formed in particular as intercooler of an internal combustion engine 2 in a motor vehicle 3, a first stacking disk package 4 and a second stacking disk package 5, each with a plurality of juxtaposed and interconnected, in particular soldered to each other, stacking disks 6 and respectively a base plate 7, via which a supply and / or discharge of a coolant 8 takes place.
  • the two stacking disk packages 4, 5 via a lying between the two base plates 7 distribution plate 9 are connected to each other and to a coolant inlet 10 and / or a coolant outlet 11.
  • the two stacking disk packages 4, 5 are interconnected via their respective base plate 7, these two base plates 7 then together forming a distributor plate 9 and also having a coolant inlet 10 and / or a coolant outlet.
  • a holder 12 is provided, which holds the stacking plate heat exchanger 1 exclusively in the center, that is on the two base plates or not according to the invention on the distributor plate 9 and thereby centrally fixed each projecting from the base plate 7 stacking disc package 4, 5.
  • Stacking disk packages 4, 5 are achieved, whereby both the base plates 7, for example, less rigid and thus less difficult to be formed and also external piping, which were often required in a one-sided connection, can be avoided on the one hand.
  • the first stacking disk package 4 is designed as a high-temperature cooler (HT) and the second stacking disk package 5 as a low-temperature cooler (LT).
  • HT high-temperature cooler
  • LT low-temperature cooler
  • both a coolant inlet 10 and a coolant outlet 11 for the first stacking disk package 4 as well as a coolant inlet 10 and a coolant outlet 11 for the second stacking disk package 5 can be provided in the distributor plate 9 or the two base plates 7 forming this distributor plate 9 (cf. Fig. 6 ).
  • both a coolant inlet 10 or a coolant outlet 11 for the first stacking disk package 4 and a coolant inlet 10 or a coolant outlet 11 for the second stacking disk package 5 are provided in the distributor plate 9 or in the two cooling plates 7 forming this distributor plate 9 are provided.
  • a coolant inlet 10 for the first stacking-disk package 4 and a coolant outlet 11 for the second stacking-disk package 5 or vice versa can likewise be provided in the distributor plate 9 or the two base plates 7.
  • a coolant inlet 10 for the first stacking-disk package 4 and a coolant outlet 11 for the second stacking-disk package 5 or vice versa can likewise be provided in the distributor plate 9 or the two base plates 7.
  • In the distributor plate 9 and in the two base plates 7 are unspecified channels for a medium to be cooled 13, for example, exhaust 14, and be arranged for coolant 8.
  • first and second stacking disk package 4, 5 each have a cover plate 15 with a passage 16 for the medium to be cooled 13, in particular for the exhaust gas 14 to be cooled.
  • the stacking disks 6 themselves or the base plates 7 and / or the distributor plate 9 can be made of a light and at the same time good heat conducting material, such as solderable aluminum, be formed.
  • An equipped with the stacked-plate heat exchanger 1 internal combustion engine 2 of a motor vehicle 3 offers the great advantage that a vibration-optimized storage is possible because the originally one-piece stacking disk package has now been divided into two stacking disk 4, 5 and thereby the respective projecting part of the stacking disk package 4, 5 is only about half as large as in the known from the prior art, unilaterally connected stacking disk packages.
  • the base plates 7 and not according to the invention the distributor plate 9 can be designed to be lighter and thus more cost-effective.
  • the two stacking disk packages 4, 5 may be substantially the same size or have a different size, in particular if, for example, a high-temperature cooler should have a higher or lower power than a downstream low-temperature cooler.
  • a connection between the two base plates or not according to the invention between these and the distributor plate 9 is, for example by means of screws 17 (see Fig. 6 ) causes.
  • the holder 12 used for this purpose can have stiffening ribs 18 (compare FIGS Fig. 1-5 ), wherein the holder 12 may be bolted to the stacked plate heat exchanger 1. In theory, even a guide of a coolant line within the holder 12 is conceivable.
