DETAILED DESCRIPTION

(12) According to FIGS. 1 to 5 and 7 to 9, a heat exchanger module 1 according to the invention has a heat exchanger device 2 for controlling the temperature of a fluid 3, for example oil, by means of a heat transfer medium 4, for example coolant, wherein the heat exchanger device 2 has a base plate 5. According to the invention at least one additional unit 6 is now arranged on this base plate 5, wherein at least one inflow line 11 and/or an outflow line 12 of the at least one additional unit 6 are/is additionally provided in the base plate 5 (see FIGS. 7 to 9). In the case of the heat exchanger 1 according to FIGS. 1 to 5, an inflow 7 and an outflow 8 for the fluid 3, which is to be temperature-controlled, as well as an inflow 9 and an outflow 10 for the heat transfer medium 4 are additionally also arranged in the base plate 5, which are embodied fluidically separated from the at least one inflow line 11 and the at least one outflow line 12 of the at least one additional unit 6.

(13) In the case of the heat exchanger 1 according to FIGS. 7 to 9, the inflow 7 and the outflow 8 for the fluid 3, which is to be temperature-controlled, as well as the inflow 9 and an outflow 10 for the heat transfer medium 4 are arranged in a cover plate 20.

(14) The additional unit 6 can for example be embodied as filter device 13, in particular as oil filter, as pump, as holder comprising duct guide for the additional unit (6), as distributor device, as valve device or as a crankcase. The heat exchanger device 2, in turn, can be embodied as plate heat exchanger 14, in particular as oil cooler. In addition or in the alternative, an additional unit 6 can also be embodied as pump 15. This pump 15 can for example be embodied as oil pump or as coolant pump. The base plate 5 itself is thereby preferably embodied as die cast component or as punched component made of metal, but, in the alternative, can obviously also be embodied as plastic injection molded part.

(15) A realization of the inflow line 11 and/or of the outflow line 12 is realized by means of a constructed duct cross section, wherein a first wall area 16, in particular in the manner of a chamfer, the inflow line 11 and/or the outflow line 12 of the at least one additional unit 6 is integrated into the base plate 5, and wherein a second wall area 17 (see FIG. 1), which completes the inflow line 11 and/or the outflow line 12 is formed by the heat exchanger device 2, in particular a heat exchanger plate 18, of the heat exchanger device 2, which is embodied as stacked plate cooler.

(16) When looking in particular at the illustration in FIGS. 2 to 5 and 7, it can be seen that the heat exchanger device 2 and the at least one additional unit 6 are arranged on opposite sides of the base plate 5, whereby it goes without saying that the arrangement of at least one additional unit 6 on the same side of the base plate 5, such as the heat exchanger device 2, is also possible in the alternative or in addition. The at least one additional unit 6 thereby preferably has a housing made of plastic.

(17) The inflow line 11 and the outflow line 12 in the base plate 5 can thereby be formed in several ways, namely of a two-part setup of a heat exchanger plate 18, which is embodied as cover plate (see FIG. 1), or of a three-part setup comprising a lower end plate 19, base plate 5 comprising ducts, which are open towards both sides, and heat exchanger plate 18, which is embodied as cover plate (see FIG. 6a), of the heat exchanger plate 18, which is embodied as cover plate, comprising integrated ducts and the additional unit 6 or a further component, respectively (see FIG. 6b) as closure.

(18) Due to the at least partial integration of the inflow line 11 and of the outflow line 12 of the additional unit 6 into the base plate 5 of the heat exchanger device 2 or of the heat exchanger module 1, the lines, which are extensive and expensive to date at this location can be integrated into the entire heat exchanger module unit in a cost-efficient and also place-optimized manner. In addition, larger structural freedoms are created to provide corresponding ducts or connections respectively. A further cost reduction is made possible by simple geometry in the area of the filter device 13, less complex tools, installation space-friendly design of the heat exchanger module and in particular a massive elimination of components, which are required to date, such as, for example, seals, lines and intermediate pieces.
