According to the heat management system of the hybrid electric vehicle, the hybrid electric vehicle and the heat management method, cooling liquid flowing out of an electric drive and water-cooling intercooling loop is cooled through a first heat exchanger and then passes through a second heat exchanger, the temperature of the cooling liquid passing through the second heat exchanger is low, and meanwhile the cooling liquid is cooled through the second heat exchanger. Cooling air passing through the second heat exchanger does not pass through other heat exchange structures, the air inlet temperature is low, the air inlet speed is high, the heat exchange efficiency is higher, and the heat exchange effect of the electric drive and water cooling intercooling system can be guaranteed. Refrigerant flowing out of the battery cooler firstly passes through the first condenser to be cooled and then passes through the second condenser, cooling air passing through the second condenser does not pass through other heat exchange structures, the air inlet temperature of the second condenser is low, the air inlet speed of the second condenser is high, the performance of the condenser can be improved, and the heat exchange effect of the power battery is guaranteed. The heat exchange capacity of an electric drive and water cooling intercooling loop is improved so as to guarantee efficient work of related parts, and it can be guaranteed that the battery cooling loop is always kept within a reasonable temperature interval.

    本申请揭示一种混合动力汽车的热管理系统、混合动力汽车及热管理方法,该方案从电驱及水冷中冷回路流出的冷却液首先经过第一换热器降温,再经过第二换热器,经过第二换热器的冷却液温度较低,同时,经过第二换热器的冷却风未经过其他换热结构,进风温度低,进风风速高,换热效率更高,能够保证电驱及水冷中冷系统的换热效果;从电池冷却器流出的制冷剂首先经过第一冷凝器降温,再经过第二冷凝器,经过第二冷凝器的冷却风未经过其他换热结构,第二冷凝器的进风温度低,进风风速高,能够提升冷凝器的性能,保证动力电池的换热效果。实现提升电驱及水冷中冷回路的换热能力以保证相关部件的高效工作,还能保证电池冷却回路始终保持在合理的温度区间。
