摘　　要：对两个直径是 2 5cm ,长度分别是 6cm和 10 0cm的两高温热管进行实验研究 (前者小热管被称为高温热管翅 ,后者大热管为普通高温热管 ) ,给出起动与运行过程的温度分布曲线。将实验现象分析比较 ,发现两热管有着相似的起动与运行过程 ,其起动温度均为 4 6 0℃左右 ,不同之处在于高温热管翅稳态工作时的温差大于普通高温热管的温差 ,普通高温热管的等温性好。Two high temperature heat pipes were tested. One of them is the small high temperature heat pipe called as high temperature heat pipe fin, the other is the long high temperature heat pipe called as the common high temperature heat pipe here. Their surface temperatures were recorded. The similar profiles during the startup and steady state period were developed. The same transition temperature, which is 460℃, was obtained. Their difference that the temperatures drop of the high temperature heat pipe fin is more than the common high temperature heat pipe during steady state period was found.
