Abstract
A heat exchanger, particularly a radiator for a motor vehicle, has a header plate which is formed with holes, each of which receives the respective end portions of a plurality of adjacent tubes, with a compressible sealing gasket being interposed between the header plate and the tube end portions. The sealing gasket has collar portions, each of which is fitted in one hole of the header plate and includes annular portions which surround the respective end portions of the tubes received in the hole. The annular portions are joined together in an intersection region having thickened zones which are adapted to be compressed between the edge of the hole in the header plate and the tube end portions received in that hole.
