| 摘 要： | 利用搭建的试验台对竖直放置的纵向肋片管的传热特性进行试验,获得了相同结构参数下肋片形式分别是开放式、平端面封闭式和弧形端面封闭式下的散热量,单位质量散热量和金属热强度。对不同的肋片管,利用正交试验得到了各因素对散热量和单位质量散热量的影响程度,并获得了试验条件下肋片管的最优结构。

| Abstract: | Tests the heat transfer performance of the finned tube in the test bed, obtains the heating capacity, heating capacity per unit weight and mental thermal intensity of three different finned tubes including opening, flat-faced closed and curved-faced closed finned tubes with the same structural parameters. Gets the degree of influencing factors based on orthogonal test,and also achieves the optimum structure of finned tube. |
