A comprehensive heat dissipation device of a large three-electricity system of an electric vehicle comprises a motor, a motor controller, a power battery, a heat exchanger, a four-way valve A, a four-way valve B, a three-way valve A and a three-way valve B. The motor, the motor controller and the power battery can all be communicated with more than one cooling liquid flowing pipeline. During use,by opening and closing each port of the four-way valve A, the four-way valve B, the three-way valve A and the three-way valve B, the motor, the motor controller and the power battery are respectivelyconnected into different cooling liquid flowing pipelines, so that a general heat dissipation mode or a limit heat dissipation mode is entered, and general working conditions or working conditions oflong-time climbing, frequent rapid acceleration and heavy load of the vehicle are adapted to. According to the design, the heat dissipation effect is good, the motor is not prone to being damaged, theinstantaneity is high, and the control efficiency is high.
一种电动车辆上大三电系统的综合散热装置,包括电机、电机控制器、动力电池、换热器、四通阀A、四通阀B、三通阀A与三通阀B,且电机、电机控制器、动力电池都能与不止一种冷却液流动管路相连通,应用时,通过对四通阀A、四通阀B、三通阀A、三通阀B上各个端口的开启与闭合,以使电机、电机控制器、动力电池分别接入不同的冷却液流动管路,从而进入一般散热模式或极限散热模式,进而适应一般工况,或者车辆长时间爬坡、频繁急加速、重载的工况。本设计不仅散热效果较好,不易损伤电机,而且即时性较强,控制效率较高。
