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.
