摘　　要：为研究低温辐射微槽道热管散热器的传热性能,首先,搭建了基于水-空气传热途径的微槽道热管散热器实验系统并进行了实测,结果显示,散热端热管阵列尺寸为0.9 m×0.5 m×0.003 m的散热器在测试条件下稳定工作时,其传热功率约为273W;然后,建立了该散热器传热过程的热阻分析模型,给出了微槽道热管散热器的三大部分热阻及其所包含的各个细分热阻的计算公式,以及依据实验数据计算了相应热阻值;最后,通过各个细分热阻的比较,分析了该系统传热过程的薄弱环节,并针对性地提出了强化传热措施。In order to study the heat transfer performance of low temperature radiation micro-grooved heat pipe radiator,an experimental system of the micro-grooved heat pipe radiator based on the water-air heat transfer path is built and tested.The results show that the heat transfer power of the heat sink with the heating end size of 0.9 m×0.5 m×0.003 m is about 273 W when it works stably under the test conditions.Then,the thermal resistance analysis model of the heat transfer process of the heat sink is established,and the calculation formulas of the thermal resistance of the three major parts of the micro-grooved heat pipe radiator and its subdivisions are given,and the corresponding thermal resistance values are calculated according to the experimental data.Finally,through the comparison of each subdivision thermal resistance,the weak links of the heat transfer process of the system are analyzed,and the measures to strengthen the heat transfer are put forward.
