[0002] As the core device of automobile transmission system, the transmission will release a large amount of heat energy in the continuous working process, so that the temperature of lubricating oil is continuously rising, and the high ambient temperature will accelerate the wear of key parts such as gears and bearings, which is easy to cause assembly failure. At present, the commonly used heat management strategy relies on the heat exchanger, and the circulating flow of the internal cooling liquid is used to realize the cooling effect. However, the heat exchanger is generally added independently, and is not directly integrated in the transmission body, so that the installation position of the heat exchanger is significantly different between different vehicle models. This non-fixed and non-uniform installation mode not only increases the design difficulty and related cost, but also affects the vehicle space layout, which is not conducive to the development of the transmission in the direction of standardization and integration.
