Abstract (en)
The heat exchanger, e.g. for a vehicle passenger compartment air-conditioning system to exchange heat between a gas and two fluids passing round separate circuits, has a series of flat spaces (3) which alternate with a first and second series (1,2) of flat chambers, separated by heat-conducting walls (4,5). The two flat chambers between each pair of spaces are in direct thermal contact for virtually the whole of their surfaces, and the width of the spaces is determined by thin, corrugated heat-conducting panels (4) inside them. Each of the flat chambers is formed from two pressed sheet metal walls with facing cavities, sealed together round their edges. They can also be joined in an intermediate zone extending for part of their length.
