摘　　要：近红外单光子探测器是量子保密通信的重要组成部分,降低其工作温度是提高探测效率的关键。文章讨论了铝合金散热器和均温板的温差特性,研究了其启动速度随热流密度变化的关系,分析了热流密度对散热器件热阻值的影响,并搭建系统进行了实验验证。结果表明:均温板散热性能优于铝合金散热器,温差能控制在2℃以内,且均温板的启动速度更快。另外,散热器尺寸对散热性能有着很大的影响,加载相同热流密度时大尺寸的均温板能耗散更多热量。因此,采用较大尺寸的均温板将有利于提升探测器的探测效率。Near infrared single photon detector is an important part of quantum secure communication,and reducing its operating temperature is the key to improve the detection efficiency.In this paper,the characteristics of temperature difference of aluminum alloy radiator and vapor chamber were discussed,the relationship between the starting speed and the change of heat flux was studied,the influence of heat flow density on the thermal resistance value of the cooling device was analyzed,and a system for experimental verification was build.The results show that the cooling performance of the vapor chamber is better than that of the aluminum alloy radiator,the temperature difference can be controlled within 2℃,and the starting speed of the vapor chamber is faster.In addition,the size of the radiator has a great influence on the heat dissipation performance.When the same heat flux is loaded,the large-size vapor chamber can dissipate more heat.Therefore,the use of a larger vapor chamber will be conducive to improve the detection efficiency.
