Abstract

In a tube-bank heat exchanger which is primarily intended for use in automotive vehicles and comprises tube sheets or headers provided with holes for mounting the tube ends in a fluid-tight manner, predetermined tubes are provided at each end with a flared-out end portion located externally of each header while other predetermined tubes are provided at each end with an annular bulge located internally of each header in order to ensure that the headers are maintained in rigidly fixed relation, thus preventing any displacement with respect to the longitudinal axis of the tubes.
