FIELD: engines and pumps.
SUBSTANCE: heat-exchange unit includes a first channel for flow of cooling liquid of the engine, the second flow channel for engine oil, third flow channel for transmission oil and several plates that are shared by the first, second and third flow channels. The first flow channel is configured to allow the engine coolant to perform heat exchange with both the engine oil and the gear oil through the plates. The second flow channel is placed in an identical layer with the third flow channel. The first flow channel is placed in a layer different from the layer of the second and third flow channel. A third flow channel is located on the side of the inlet, and the second flow channel is located on a side issue in the engine coolant flow direction in the first flowing channel.
EFFECT: increase in the level of temperature stability.
