The invention discloses a cooling device for an electric control driving system of an electric sanitation vehicle. The device comprises a mounting base, a walking motor controller and a high-pressurewater pump motor controller are fixedly mounted on the mounting base, cooling fans are mounted on one side of the walking motor controller and one side of the high-pressure water pump motor controllerrespectively, cooling air channels are formed in the outer sides of the cooling fans, and air outlets of the cooling fans are communicated with the cooling air channels; a walking motor is arranged below the mounting base, and air outlets of the cooling air channels directly face a machine body of the walking motor. According to the structure of the device, multi-space installation is carried outby fully utilizing the electric control drive installation position of the sanitation vehicle; the cooling fans are used for generating air convection for cooling, the electric control driving systemof the electric sanitation vehicle can normally and continuously work in a working environment of over 40 DEG C, the working temperature of the controller and the driving motor does not exceed the protection limit value under cooling, and the motor and the controller cannot be protected and stopped and cannot be damaged due to the too high working temperature.

    本发明公开了一种电动环卫车电控驱动系统冷却装置,包括安装座,安装座上固定安装有行走电机控制器和高压水泵电机控制器,在行走电机控制器、高压水泵电机控制器的一侧分别安装有冷却风扇,冷却风扇的外侧设置有冷却风道且冷却风扇的出风口与冷却风道相连通;安装座的下方设置有行走电机,冷却风道的出风口正对行走电机的机身;此装置结构上充分利用环卫车电控驱动安装的位置进行多空间安装,利用冷却风扇产生空气对流进行冷却,可以使电动环卫车的电控驱动系统在40℃以上的工作环境也能正常连续工作,控制器和驱动电机在其冷却下工作温度不超过保护限值,电机及控制器不会保护停机,也不会因工作温度过高损坏。
