HEAT EXCHANGER

摘要

A heat exchanger includes a housing having first and second longitudinal housing walls disposed in opposite relationship, and plural cartridges which are made from extruded aluminum sections and have channels for flow of a first medium there through. The cartridges are received in the housing in alternating relationship in several rows to thereby define a multiple S-shaped curved flow path for flow of a second medium around the cartridges, with a first longitudinal side of each of the cartridges touching one of the first and second housing walls and with an opposite second longitudinal side thereof positioned at a distance to the other one of the first and second housing walls.
