The invention discloses a thermal management system and method for an electric forklift. The system comprises a controller, an electronic water pump, a walking motor, a lifting motor and a radiator, and the electronic water pump is in signal connection with the controller; the input end of the electronic water pump is communicated with the expansion kettle, the output end of the electronic water pump is sequentially provided with a dual-motor controller and an electric waterway three-way valve, the output end of the electric waterway three-way valve is connected with the input end of the walking motor and the input end of the lifting motor, and the electric waterway three-way valve is in signal connection with the controller; the output end of the walking motor and the output end of the lifting motor both communicate with the input end of the cooling header pipe, and a radiator is arranged between the output end of the cooling header pipe and the input end of the electronic water pump. The cooling water is distributed to the working motor through the electric waterway three-way valves at the front ends of the walking motor and the lifting motor, so that the cooling liquid is prevented from being provided for the motor which does not need to be cooled, and the overall cooling efficiency and the reliability of the motor and the controller thereof are improved.

    本申请公开了一种电动叉车的热管理系统及方法,系统包括控制器、电子水泵、行走电机、举升电机以及散热器,电子水泵与控制器信号连接;电子水泵的输入端与膨胀水壶连通,电子水泵的输出端依次设有双电机控制器和电动水路三通阀,电动水路三通阀的输出端与行走电机的输入端和举升电机的输入端连接,电动水路三通阀与控制器信号连接;行走电机的输出端和举升电机的输出端均与冷却总管的输入端连通,冷却总管的输出端与电子水泵的输入端之间设有散热器。本申请通过行走电机和举升电机前端的电动水路三通阀将冷却水分配给正在工作的电机,避免给不需要冷却的电机提供冷却液,提高整体的冷却效率以及电机及其控制器的可靠性。
