摘要
通过在热管内插入铜丝网吸液芯的实验,基于不同目数铜丝网结构对热管传热性能起主要影响作用的重力热管启动时间、稳定温度和热阻等因素进行分析研究.实验结果表明:在相同工况下,不同目数的铜丝网吸液芯重力热管与普通热管相比均会缩短热管的启动时间,铜丝网吸液芯目数小的热管具有更低的稳定温度;热阻随着铜丝网 目数的增加先减小后增加,在实验研究范围内,3#管具有最好的传热性能.实验结果可为重力热管强化传热研究提供方向.
Abstract
Through the experiment of inserting copper wire mesh wick into the heat pipe,the thermal re-sistance factors such as the starting time,stable temperature and thermal resistance of the gravity heat pipe which mainly affect the heat transfer performance of the heat pipe with different mesh number copper wire mesh structure are analyzed and studied.The experimental results show that under the same working con-ditions,the start-up time of the heat pipe with different mesh size is shorter than that of the ordinary heat pipe,and the heat pipe with small mesh size has lower stable temperature.The thermal resistance first de-creases and then increases with the increase of mesh size.In the scope of this experiment,3# tube has the best heat transfer performance.This experiment provides a direction for the study of heat transfer enhance-ment of gravity heat pipe.
