| 摘 要： | 针对增温型吸收热泵的一级装置，对热管外壁面装有轴向翅片的热管式降膜吸收器的降膜传热传质过程进行了数值研究，在假定壁温和翅片温度恒定及降膜厚度不变的基础上，对几组不同翅片高度和间距的情况进行了计算，结果表明，在离入口一定距离范围内，由于翅片的冷却作用而明显了降膜传热传质。 |

| Abstract: | A numerical study was carried out to determine the effects of axial finned tubes on the transport characteristics of falling film absoption in heat pipe type absorbers. The temperature of the wall including the fin was assumed to be constant, and the falling film was assumed to have a constant thickness. Calculations were performed for several combinations of fin height and fin pitch. It was shown that the transport rate was significantly enhanced by the fin cooling effect within a certain distance from inlet. |
