摘要:电池组温度的均匀性问题,一直是人们所关注的热点问题。作为高效电池热管理技术之一的液冷技术,其冷板的结构是制约电池组冷却效果好坏的关键因素。本文采用CFD模拟研究了三种不同流道结构的冷板对空间电池组冷却效果的影响。结果表明:采用S型冷板进行冷却时,电池单体温差较小,电池单体温度分布相对较均匀,其次是Z型冷板,普通U型冷板冷却时的电池单体温差较大;电池组的最高、最低温度随冷却水流速增加而降低,但下降趋缓;同时,冷板的进出口压力损失均增大。以上研究对液冷冷板流道结构设计有一定的借鉴意义。
Abstract: The temperature uniformity of the battery pack problem, has been the hot issue of concern. As one of high efficient battery thermal management technology of liquid cooling technology, its cold plate geometry is the key factor that restricts of battery pack cooling effect. In this paper, the influence of three different channel geometries of cold plates on space battery cooling effect is studied by using CFD simulation. the results show that using S type cold plate for cooling, the temperature difference was small, and the battery monomer had relatively uniform temperature distribution; the second was the Z type cold plate, but the temperature difference was bigger when ordinary U cold plate cooling. with the increase of the water flow rate, the maximum and minimum temperature of space batteries both decreased, but the decline slowed down; besides, the pressure drop increased. This research has certain reference significance for the design of liquid cooling plate flow channel geometry.
