本文运用相似理论,通过对常用的两种翅片热管的对比实验,找出两种翅片热管热阻及传热特性的差别,给出准则形式函数表达式,提出了热管换热器设计中对翅片热管的选择原则。 In this paper, the similar theory is used to compare the thermal resistance and heat transfer characteristics of two kinds of finned heat pipes by comparing the commonly used two kinds of finned heat pipes. The expression of canonical form function is given, and the heat pipe heat exchanger design The choice of fin heat pipe principle.
