The invention discloses a heat management system, a control method and a vehicle. The heat management system comprises a compressor, an outdoor heat exchanger, a power battery, a gas-liquid separator, an evaporator and a heat management integrated unit. The heat management integrated unit comprises a runner plate, a pump assembly, a valve assembly, a water-cooled condenser, a water-water heat exchanger and a battery cooler. In a first working mode, the battery water pump and the compressor are both started, the valve assembly is in a first preset state, the battery water pump conveys cooling liquid to the power battery and then flows through the battery cooler, and a refrigerant flows through the water-cooling condenser under the action of the compressor and then enters the outdoor heat exchanger to be cooled; and when the cooled refrigerant flows through the battery cooler, the cooled refrigerant exchanges heat with the cooling liquid flowing through the battery cooler so as to cool the cooling liquid, so that the power battery is cooled. Therefore, the refrigerant can be adopted to perform forced cooling on the battery so as to improve the heat dissipation performance of the power battery, and the safety performance and the charging speed are improved.

    本发明公开了一种热管理系统、控制方法和车辆,热管理系统包括压缩机、室外换热器、动力电池、气液分离器、蒸发器和热管理集成单元。热管理集成单元包括流道板、泵组件、阀组件、水冷冷凝器、水水换热器和电池冷却器。在第一工作模式下,电池水泵和压缩机均启动,阀组件处于第一预设状态,电池水泵将冷却液输送至动力电池后流经电池冷却器,冷媒在压缩机的作用下流经水冷冷凝器后进入室外换热器中进行冷却,冷却后的冷媒流经电池冷却器时与流经电池冷却器的冷却液进行热交换以对冷却液进行冷却,从而对动力电池进行冷却。如此,可采用冷媒对电池进行强制冷却以提高动力电池的散热能提,提高安全性能和充电速度。
