摘要
为保证空间电池组温度的均匀性,采用数值模拟研究了普通U型、S型和Z型三种不同流道结构冷板随流道尺寸对电池组温度分布的作用及影响。结果表明:任一尺寸下,采用普通U冷板的电池组温度均较高,冷却效果都较差;S型冷板在流道宽度为5mm、间距为5mm、高低度为10mm时,对电池组冷却效果较好,进出口压差较小;随着流道尺寸的缩减,S型冷板对电池组的冷却效果虽好,但进出口压差较大,需要的泵耗较大;流道尺寸缩小时,采用Z型冷板既能合理的控制电池组的温度,又能减小冷板的进出口压差,泵耗较低。同时,冷板的进出口压差均增大。以上结论为冷板流道结构设计提供了重要依据。
In order to ensure the temperature uniformity of space batteries,three different flow geometries of cold plates were studied by numerical simulation,which was along with the changes of flow channel size.Results show that under any size,the battery temperature of the ordinary U cold plate is higher and the cooling effect is worse;the cooling effect of S-type cold plate that channel size in 5 mm width,5 mm spacing,10 mm height is better,and the pressure drop between the inlet and outlet is small.With a reduction in flow channel size,S-type cold plate has a good cooling performance on the battery pack,but the inlet-outlet pressure drop is larger,thus the pump consumption is large;When the channel size is reduced,the Z-type cold plate can not only properly control the temperature of the battery pack,but also reduce pressure drop of cold plate,and the pump consumption is low.These results are beneficial to the design and improvement of flow geometries.
