| 摘 要： | 本文介绍了一种具有较好传热传质性能的吸附式制冷用吸附单元管,该吸附单元管直接用烟气加热、空气冷却, 可以用于沸石等高温吸附剂。该吸附单元管在加热／冷却流体侧和吸附剂侧均设了翅片,吸附剂内部的传热尺度不大于 2．5 mm,最大传质尺度不大于11 mm。通过数值计算和由吸附单元管组合而成的吸附床的性能初步试验,证明该结构形式的吸附单元管具有优良的传热传质性能。

| Abstract: | An adsorption unit tube with good heat and mass transfer performance is introduced in this work. This tube can be heated by exhausted gases from engine and cooled by air directly. It can be used in the zeolite adsorption system. The fins installed in both the heating/cooling fluid side and the adsorbent side of the tube cause the dimensions of the heat transfer and the mass transfer less than 2.5 mm and 11 mm respectively. The simulations on the tube and the primary experiments on the adsorber combined by the unit tubes indicate that the heat and mass transfer performance of the adsorption unit tube is very good. |
