The invention relates to a power assembly cooling system and a vehicle. The power assembly cooling system comprises an oil cooler of a gearbox and a radiator connected into engine cooling liquid circulation. The radiator comprises a first radiating portion and a second radiating portion which are separated, cooling liquid flowing out of the first radiating portion and cooling liquid flowing out ofthe oil cooler are mixed, and part of the mixed cooling liquid sequentially flows through the second radiating portion and the oil cooler through a water pipe and flows back into the engine. Therefore, the cooling liquid flowing out of the first radiating portion and the oil cooler can partially enter the second radiating portion to be subjected to secondary cooling; the power assembly cooling system can meet the heat dissipation requirements of an engine and a gearbox at the same time, the heat dissipation effect on lubricating oil in the oil cooler is further improved, the overall structureis compact, and the occupied space is small.

    本公开涉及一种动力总成冷却系统和车辆,动力总成冷却系统包括变速箱的油冷器和接入到发动机冷却液循环中的散热器,所述散热器包括相分隔的第一散热部和第二散热部,所述第一散热部和油冷器流出的冷却液进行混合,且混合后的部分冷却液通过水管依次流经所述第二散热部、油冷器并回流至发动机中。这样,由第一散热部和油冷器流出的冷却液部分可进入第二散热部内进行二次降温,进一步降低冷却液的温度,可满足变速箱的散热需求,本公开提供的动力总成冷却系统可同时满足发动机和变速箱的散热需求,进一步提升了对油冷器内润滑油的散热效果,整体结构紧凑,占用空间小。
