Abstract:
1. A cooling device for engine and/or transmission oil cycling through an oil trough formed with oil trough walls, the cooling device comprising: a plate heat exchanger forming an oil cooler in the oil trough, said plate heat exchanger being suspended in the oil trough from an upper wall at a defined spacing from the oil trough walls surrounding said plate heat exchanger; said plate heat exchanger having plates disposed to form first plate intermediate spaces therebetween conducting a coolant flow therethrough and second plate intermediate spaces conducting the oil therethrough; said second plate intermediate spaces having an outer opening region on an outer circumference of said plate heat exchanger, forming an inflow region for hot oil to be cooled to flow into said second plate intermediate spaces; said second plate intermediate spaces having an outer outflow region on the outer circumference of said plate heat exchanger distally from said inflow region and connected indirectly or directly to an outer oil line connection, for cooled oil to flow out after traversing said second plate intermediate spaces and after exchanging heat with the coolant; one or more attachment devices consisting of at least one heat exchanger bearing element fixing said plate heat exchanger on an oil trough side; said at least one heat exchanger bearing element being an insert plate or a yoke plate or an insert plate integrated into a yoke plate; and wherein: coolant channels, flow-connected to at least one part of said first plate intermediate spaces routing coolant, are formed integrated in said at least one heat exchanger bearing element; said coolant channels connected to said first plate intermediate spaces are formed by coolant channels that are at least partially integrated into a housing wall of the oil trough; said coolant channels that are integrated into said at least one heat exchanger bearing element are fluidically connected to at least one part of said coolant channels that are integrated into the housing wall of the oil trough; and said coolant channels are formed by a plurality of bores communicating with one another.
