HEAT AND MATERIAL EXCHANGE DEVICE AND MANUFACTURING PROCESS

摘要

A jacket encloses a packet of corrugated plates (3) each disposed in a generally vertical plane, the corrugations being oblique and descending in opposite directions from one plate to the following plate. Each corrugation valley (5) has a lower end opening out laterally which includes a projecting obstacle (7) in the vicinity of this lower end. In this way, liquid that would otherwise accumulate on the vertical walls of the jacket, where it would participate relatively little in heat and material exchange, is instead diverted toward the interior.
