ABSTRACT

An intermittent spray cooling system is applied to fuel cell vehicle heat dissipation using a plate-fin heat exchanger. The effects of various system parameters on cooling performances are evaluated. Experimental results indicate that the cooling performance can be increased by 20% to 80% at various operating conditions and fixed spray area percentage of 45%. An empirical correlation is constructed to characterize heat transfer enhancement percentage. For the 124 data points examined, 92.73% of the data are within 20% of the error range, and 81.8% are within 15% of the error range. The average absolute deviation is 9.30%.

板翅式换热器喷雾冷却系统传热特性试验研究

摘要

采用板翅式换热器将间歇式喷雾冷却系统应用于燃料电池汽车散热。评估了各种系统参数对冷却性能的影响。实验结果表明，在各种操作条件和固定喷雾面积百分比为 45% 的情况下，冷却性能可提高 20% 至 80%。构建了一个经验关系式来表征传热增强百分比。对于检查的 124 个数据点，92.73% 的数据在 20% 的误差范围内，81.8% 的数据在 15% 的误差范围内。平均绝对偏差为 9.30%。
