The invention discloses a cooling method and system for a hybrid electric vehicle and the hybrid electric vehicle. According to the scheme, a coupling radiator and a fluid on-off device are arranged, and first temperature information of a first cooling loop and second temperature information of a second cooling loop are obtained; the first temperature information is compared with a first temperature threshold value, the second temperature information is compared with a second temperature threshold value, the first temperature threshold value is smaller than the second temperature threshold value, and when the first temperature information is lower than the first temperature threshold value and the second temperature information is higher than the second temperature threshold value, the first temperature information and the second temperature information are compared; the fluid on-off control device conducts a flow path between the first fluid channel and the first to-be-cooled component and the first radiator and conducts a flow path between the second fluid channel and the second to-be-cooled component and the second radiator, and cooling liquid of the second cooling loop is pre-cooled through cooling liquid of the first cooling loop. The cooling effect of the second cooling loop can be improved, and therefore the heat dissipation capacity of the whole cooling system is improved.

    本申请揭示一种用于混合动力汽车的冷却方法、冷却系统及混合动力汽车,该方案设置耦合散热器、流体通断装置,通过获取第一冷却回路的第一温度信息和第二冷却回路的第二温度信息,并比较第一温度信息与第一温度阈值的大小以及第二温度信息与第二温度阈值的大小,第一温度阈值小于第二温度阈值,当第一温度信息低于第一温度阈值,且第二温度信息高于第二温度阈值,控制流体通断装置导通第一流体通道与第一待散热部件和第一散热器之间的流路、第二流体通道与第二待散热部件和第二散热器之间的流路,通过第一冷却回路的冷却液给第二冷却回路的冷却液预冷,可以提高第二冷却回路的冷却效果,从而提高整个冷却系统的散热能力。
