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.
