摘要
新能源汽车高压电气产品具有自发热、自带冷却液循环的特点,其温度效应不同于常规低压电器,不能按照诸如GB/T 28046 等电气及电子设备环境可靠性试验方法进行.本文通过搭建试验台架,掌握了带液冷循环高压产品的温度分布情况,并建立与冷却液温度相匹配的可靠性试验方法.
Abstract
High voltage electrical products of new energy vehicles have the characteristics of self heating and self cooling liquid circulation,and their temperature effect is different from conventional low-voltage electrical appliances.They cannot be tested according to environmental reliability test methods such as GB/T28046 for electrical and electronic equipment.This article grasps the temperature distribution of high-pressure products with liquid cooling circulation by building a test bench.And establish a reliability testing method that matches the cooling night temperature.
