ABSTRACT:
A heat exchanger comprises a fluid box in the form of an elongated vessel having two side walls, two end walls and a base wall, the fluid box being sealingly closed by a welded cover plate on the side opposite to the base wall. The heat exchanger also has at least one bank of tubes which lie mainly outside the fluid box and which communicate sealingly with the interior of the latter through holes formed in the base wall. The side walls of the fluid box extend generally parallel to the plane containing the axes of the tubes of one bank, and include in the vicinity of the cover plate a shoulder which is directed outwardly to serve as a support for welding the cover plate in position. The distance, measured in a transverse direction, between the inner face of each side wall of the fluid box and the axes of the tubes of the bank of tubes closest to it is, at the level of the shoulder smaller than the maximum dimension of the tubes in the same transverse direction. This is achieved mainly by virtue of a hip formed in the side walls, which reduces the overall width of the heat exchanger.
