Heat-exchange element

摘要

A heat-exchange element (10) has a plurality of heat-exchange components (11) each having a circular heat-exchange plate (12). The circular heat-exchange plate has a plurality of ribs (13) projecting from a surface thereof and extending generally in one direction. The outer circumferential edge of the circular heat-exchange plate is divided into four substantially equal edges. The circular heat-exchange plate includes a pair of sealing ribs (14) extending respectively along two diametrically opposite ones of the edges substantially parallel to the ribs, and a pair of end walls (15) extending respectively along two other diametrically opposite ones of the edges substantially transversely to the ribs (13). The heat-exchange components (11) are stacked into a cylindrical shape in which the end walls of each of the circular heat-exchange plates (12) fittingly engage the sealing ribs (14) of another one of the circular heat-exchange plates (12).
