In this paper, research is focused on the heat and mass transfer features during absorption process on the two-scale corrugation plate surfaces of plate-shell heat exchangers. This new Kind structure has vertical large corrugations and horizontal small ones, which can enhance the convection heat transfer of cooling water at internal plate channel side and make the liquid falling film uniformly distributed and turbulent by twisting path, so that the heat and mass transfer characteristics at both sides can be enhanced while sufficient flow area for adequate resistance requirement is also met.

本论文围绕一种新型交叉双尺度波纹板片组成的板壳式吸收器进行研究，这种新型传热元件的相邻板片的竖直大波纹相顶靠，形成曲折的板内通道和菱形板外通道，可强化板内侧冷却水的对流传热，而其水平小波纹则可对布膜的溴化锂浓溶液和冷剂蒸汽产生连续的扰动，使液膜分布均匀，传热传质得到强化。
