Abstract
A heat exchanger for a heating or cooling circuit of a motor vehicle comprises a header plate with a header cover sealingly secured over it, and a number of tubes extending through the header plate. The outer flanks of the collar portions of the header plate, which surround the ends of the tubes situated at the ends of the row of tubes are joined directly, along an inclined plane, to the peripheral channel in which the peripheral edge portion of the header cover is received. The overall length of the header plate, and therefore that of the heat exchanger as a whole, is thereby reduced.
Claims8
A header plate for a heat exchanger comprising said header plate, a header cover sealingly secured on the header plate to define a header space between them, and a bundle of tubes extending through the header plate and open into the header space, the header cover having a peripheral edge portion, the header plate comprising:
- a central plate element defining a plane and extending substantially in the said plane;
- a peripheral region defining an annular channel receiving the said peripheral edge portion of the header cover;
- and a plurality of inclined annular collar portions, each defining a through aperture bounded by the collar portion, for the fitting of a respective said tube in each said aperture, the peripheral region extending from the said plane on one side of the said plane, and the collar portions extending from the said plane on the other side of the said plane, wherein the said channel has an inner side wall having a profile which, in some zones of the length of the channel, is joined directly to the profile of an adjacent said collar portion without passing through the direction of the said plane.
