Plate type heat exchanger with flat tube nest

摘要

First chambers (17), e.g. for oil, and second chambers (27), e.g. for water, are formed in the dive-shaped flat tubes (16,26). The chambers are interconnected by two transverse ducts, one for the feed and the other for discharge of the water forming the second medium. The first and second chambers are formed by their respective first (16) and second (26) flat tubes, between which are formed intermediate chambers (33) with partitions (34,35). Pref. between the latter and the contacted flat tubes are formed intermediate chambers (26) interconnected in each plane and leading to the nest of tubes (1) outside.
