摘要
为优化室内地暖的散热效果,应用石墨烯超导冷暖技术,设计石墨烯超导热管,并通过实验研究石墨烯超导热管散热性能.选取石墨烯超导热管、铝极干式热管和传统湿式热管,构建热管实验装置,分别对3种热管的散热性能进行测试,并将测试结果通过数据处理与误差分析方法进行处理.经实验可知:传统湿式热管在热管启动时启动温度上升速度最慢,且在不同充液率下始终保持较低的导热系数、较高的热阻,说明该热管的散热性能较弱;而铝极干式热管在测试时虽然具备一定的散热能力,但依然弱于石墨烯超导热管;在石墨烯超导热管测试过程中,其在不同启动温度下均能迅速达到相应温度,且总热阻较低、导热系数较高,可迅速实现散热.当导管的充液率较高时,热管的冷凝段和蒸发段的温差较低,具有较好的散热效果,且石墨烯超导材料还能够提高热管强化作用率,使热管散热效果更强.
Abstract
For purpose of optimizing heat dissipation effect of indoor floor heating,having graphene super-conducting heating and cooling technology applied to design graphene superconducting heat pipe was im-plemented,including investigating its heat dissipation performance through experiments.In which,having the graphene superconducting heat pipe,aluminum electrode dry heat pipe and the traditional wet heat pipe selected to build a heat pipe experimental device to test their heat dissipation performance,respectively,including having data processing and error analysis methods adopted to process test results.The experimen-tal result shows that,the starting temperature of the traditional wet heat pipe rises slowest when the heat pipe starts,and it always maintains a low thermal conductivity and a high thermal resistance at different liquid-filling rates,which indicates a weak heat pipe's heat dissipation performance;when the extremely-dry aluminum heat pipe has a certain heat dissipation capacity during the test,it is still weaker than the graphene superconducting heat pipe's;during testing graphene superconducting heat pipe,it can quickly reach the corresponding temperature at different starting temperatures,and its total thermal resistance be-comes low and its thermal conductivity is high,which can quickly realize heat dissipation.Higher pipe's liquid-filling rate and lower temperature difference between the heat pipe's condensing section and evapo-rating section can bring about good heat dissipation effect.The graphene superconducting material can im-prove the heat pipe's reinforcement rate and make heat pipe's heat dissipation effect stronger.
