摘要
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 tem-perature,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.关键词
