| 摘 要： | 主要针对换热板溶液侧的几何形状对吸收器性能的影响进行实验研究。在相同的条件下以光滑平板为比较对象，对开有纵向沟槽和横向沟槽(翅片)的各种换热板进行了比较实验。实验结果表明，在本实验的条件范围内，开有宽度为1mm的纵向沟槽换热板的性能较好，在液膜雷诺数为75时其传热系数是光滑板的1．44倍。

| Abstract: | Mainly focus on the effects of geometric configurations of heat transfer plate on the performance of absorber.For a plate-type absorber with different geometric configurations of heat transfer plate(bare,finned,and grooved),experiments were conducted for the solution film Reynolds numbers of 20~150,at a constant concentration of strong solution of 62 wt% at the entrance of absorber.Among different geometric shapes of heat transfer plate,1 mm vertical grooved plate showed its advantageous performance in present study.The heat transfer coefficient of this kind plate was 1.44 times of that of bare plate at solution film Reynolds Number 75. |
