ABSTRACT:
A heat exchanger, in particular an engine cooling and/or cabin air heating radiator for a motor vehicle, has a header plate formed with holes, in which each hole receives the respective end portions of a plurality of adjacent tubes in different sets of tubes in the tube bundle of the radiator. A sealing gasket is interposed between the header plate and the tubes. The tube end portions and the corresponding holes have cross sections of conjugate shapes which define between them annular gaps of substantially constant width, these annular gaps being joined, in each hole, by an intersection region having a substantially constant width.
