Heat exchanger or material exchange column packing element assembly

摘要

The heat exchanger or material exchange column or vessel for gases and/or liquids is packed with a substrate element (1) on which the reaction or exchange takes place, as the gas or fluid flow passes over the numerous surfaces (104) incorporated in the element (100). The surfaces (104) are formed by half-wave or full-wave strips (103, 103a-103f) and the element (100) incorporates a first gp. of strips (102a) which are of half-wave or full-wave (103a, 103b) of period length l1, followed by a second gp. of strips (102b) incorporating half-wave or full-wave strips (103c, 103d) with a second period length l2.
