The invention provides a heat dissipation system, an electric vehicle and a heat dissipation method.The heat dissipation system comprises a transmission motor, a hydraulic motor and a hydraulic water pump, a motor shaft of the hydraulic motor is connected with fan blades, and the hydraulic water pump is used for driving cooling water to circulate; a first high-pressure oil channel used for oil circulation is arranged between the hydraulic pump and the hydraulic motor, and a second high-pressure oil channel used for oil communication is arranged between the hydraulic pump and the hydraulic water pump. The heat dissipation system has the beneficial effects that the hydraulic motor and the hydraulic water pump are made to conduct heat dissipation work through the hydraulic pump, an adopted power source is the transmission motor instead of a battery of the whole vehicle, the hydraulic pump can work as long as the vehicle runs, the heat dissipation system is low in energy consumption, and the service life of the battery of the electric vehicle can be greatly prolonged.

    本发明提供了一种散热系统、电车以及散热方法,属于车辆散热的技术领域,包括:传动电机、液压马达以及液压水泵,所述液压马达的电机轴连接有风扇叶片,所述液压水泵用于驱动冷却水循环:液压泵,所述液压泵与所述传动电机联动连接,所述液压泵与所述液压马达之间设置有用于油液流通的第一高压油通道,所述液压泵与所述液压水泵之间设置有用于油液连通的第二高压油通道。本发明的有益效果:本散热系统通过液压泵来使液压马达以及液压水泵进行散热工作,其采用的动力源是传动电机而不是整车的电池,只要车辆行驶就能使液压泵工作,这样的散热系统不仅能耗低,还能够极大地增加电车的电池寿命。
