Heat exchanger

A tank part for connection to a header part to form a heat exchanger manifold, which tank part comprises an elongate generally channel-shaped member and at least one partition member fitted in the channel to extend transversely thereacross, wherein the tank part is provided with inwardly deformed regions on opposite sides of the at least one partition member in the longitudinal direction of the tank part to retain the at least one partition in position, and wherein the channel member has longitudinal edge regions which are provided with upstanding portions at the location of the at least one partition, regions of these upstanding portions constituting tabs which are bent inwardly on the opposite sides of the at least one partition in order to hold an upper region thereof in position.

A heat exchanger manifold comprising elongate generally channel-shaped tank and header parts joined to form a tubular manifold body, and at least one transverse partition member fitted therein, wherein the tank part is provided with inwardly deformed regions on opposite sides, in the longitudinal direction of the manifold, of the at least one partition member, and wherein the inwardly deformed regions have two pairs of inwardly protruding dimples formed in the wall of the tank part.

A heat exchanger comprising at least one tubular manifold having separate tank and header parts joined along longitudinal edges thereof, said header part defining a plurality of apertures therein;

• a plurality of heat exchange tubes each extending through a respective aperture to communicate internally with the manifold and at least one partition member disposed transversely in the manifold;
• wherein the tank part is provided with inwardly extending deformed regions on opposite sides of the at least one partition member, and wherein the inwardly deformed regions have two pairs of inwardly protruding dimples formed in the wall of the tank part.
