Heat exchanger assembly - has support points on tubes near tube bases and exchanger ribs

摘要

The heat exchanger, for a water/air cooler, consists of parallel flat tubes (1), with their ends held sealed in openings (2) of tube bases (3). Lamellar heat exchanger ribs (4) are located between the tubes, and there are support points between the tubes near the tube bases. The support points (5) are located on the side of the tube bases away from the free tube ends, in the area of the exchanger ribs. The points are formed as engaging raised sections, which are pressed inwards out of opposite tube ealls (1b).
