ABSTRACT:
A tubular heat exchanger for a motor vehicle has a header comprising a header plate and a header cover brazed to the header plate. The header plate has a base portion which is arranged to be joined to the bundle of tubes of the heat exchanger, and the header cover is terminated by a peripheral edge portion which is engaged within a peripheral flange of the header cover surrounding the base portion of the latter. This base portion is provided with a multiplicity of press-formed projecting elements which are spaced apart close to the peripheral flange, and the peripheral edge portion of the header cover is held in contact with the header plate flange by these projecting elements prior to the brazing operation by which the edge portion of the cover is brazed to the header plate flange.
