摘要：  对锂/亚硫酰氯电池在水下航行器电池舱段中的发热和传热过程进行理论分析，在给定的工况下，对电池舱段内部发热和传热过程进行试验测量，利用FLUENT软件仿真分析了电池架导热系数对电池舱段内部温度随时间的变化规律和温度分布云图的影响.结果表明，电池舱段内部最高温度随着电池架导热系数增加而逐渐降低；采用铝基电池架能够满足该型号水下航行器在温度控制方面的工况要求(≤70 °C)，且具有一定的温度裕量.

Abstract: Thermal process inside battery compartment of underwater vehicle was theoretically analyzed and experimentally measured when batteries are discharging under some working condition. Otherwise, temperaturetime curves and temperature contours inside battery compartment were simulated by FLUENT software when heat conductivity of battery framework is different. It is indicated that when the heat conductivity of battery framework is higher, the maximum temperature inside compartment is lower, meanwhile, using aluminum framework can lower the maximum temperature to 64 °C, which can meet the temperature requirement (≤70 °C).

Key words: liquid-solid coupled heat transfer, lithium/thiony chloride battery, battery framework, battery compartment
