本文主要介绍了日本古河电气公司最新开发的用于吸收式制冷机的蒸发器和吸收器中的高效传热管,这些管的外表面有低而密的翅。另外在这些管的内表面都有凸缘,使蒸发传热系数和吸收传热系数均有很大的提高。使用这些新开发的高效传热管后可使吸收式制冷机的能效比提高很多,有利于推广使用吸收式制冷机。 This article mainly introduces the highly developed heat transfer tubes used in Japan’s Furukawa Electric Co., Ltd. for evaporators and absorbers for absorption refrigerators. The outer surfaces of these tubes have low and dense fins. In addition there are flanges on the inner surface of these tubes, so that the evaporation heat transfer coefficient and absorption heat transfer coefficient are greatly improved. The use of these newly developed and efficient heat transfer tubes can increase the energy efficiency of absorption chillers so much that it is beneficial to promote the use of absorption chillers.
