摘要:
为考察热管冷板在机载条件下的适用性,设计一种温度循环试验方案对不同类型及同类型不同配置方式的9种热管冷板进行试验研究。根据温度循环前后红外热像仪测试结果分析不同热管冷板的传热性能差异,并基于试验结果采用阿雷尼乌斯公式进行寿命预估。研究表明:温度循环前后,铝均温板因产生不凝性气体导致传热性能恶化,普通铜水热管冷板与微热管阵列冷板传热性能均未发生改变,可靠性较好; 未发生恶化的热管冷板在最高工作温度下预估寿命至少为6 627 h,可满足使用寿命要求。研究工作可为机载热管冷板的选择与设计提供参考依据。
Abstract:
In order to investigate the applicability of heat pipe cold plate under airborne environmental conditions,a temperature cycle test program is proposed to study the nine kinds of different heat pipe cold plates.According to the results tested by infrared thermal imager before and after temperature cycle,the performance differences of different heat pipe cold plates are analyzed.Based on the test results,the life time is predicted by the Arrhenius equation.The results show that the heat transfer characteristics of vapor chamber is deteriorated due to non-condensable gas generated before and after temperature cycle,but the performance of ordinary copper-water heat pipe cold plate and micro-heat pipe arrays have no change and they have better reliability; the estimated life time of unchanged heat pipe cold plates can be at least 6 627 hours at the highest operating temperature,meeting the life requirements.The research can provide some foundation for the selection and design of the heat pipe cold plate used for cooling the airborne electronic equipment.
