摘　　要：为研究高温热管翅强化传热的性能 ,对带有热管翅片的单管进行了实验研究 ,给出了实验传热系数曲线及其准则关系式 ,并与光管换热关联式进行比较 ,结果表明用热管翅做翅片强化管内换热效果明显 。In order to investigate heat transfer performance on heat exchanger with heat pipe fins, a duct with high temperature heat pipe fins was tested. The convection heat transfer coefficient profile was given. The corresponding convection correlation was obtained. The result shows that convection heat transfer capability on a duct with high temperature heat pipe fin is enhanced and the heat transfer coefficient is much higher than smooth duct.
