Heat exchanger using plate element stands element it spirals round center feed and offtake tube using several elements offset round tube preferably in sectors.

摘要

A heat exchange element (6) spirals verticaly round a central feed and offtake (4) within the housing (2). Several spiraled heat exchanger plates (6) are used offset round the central line (4), each plate composed of flexibly interconnected single elements and furnished with top surface channel for the heat exchange medium. The channel comes in tube form and is joined at both ends to the medium feed and offtake lines. The channel tubes are preferably separate and arranged in sectors on the element (6) and joined to the feed and offtake lines.
