Abstract
A heat exchanger, particularly for a motor vehicle, comprises a bundle of finned tubes, with each tube having an end portion which is sealingly mounted in a hole formed in a header plate on which a casing of a water header of the heat exchanger is secured. The heat exchanger has at least one locating or immobilising member interposed between the tube bundle and the water header. This locating member has a first portion which bears on the header and a second portion which extends parallel to the longitudinal direction of the tubes in the bundle, and which bears against the longitudinal edges of a group of several fins adjacent to the header plate. In this way any relative displacement of the tube bundle with respect to the header plate, in particular in a pivoting or torsional mode, is resisted.
