Abstract

A heat exchanger comprising: a core (30; 30') comprising a plurality of parallel tubes (31; 31'), a header plate (11; 11') having a plurality of openings, into which ends of the tubes (31; 31') are inserted, and a header tank (10; 10') joined to the header plate (11; 11') and cooperating with the header plate (11; 11') to form a fluid inlet chamber (43; 43'), said header tank (10; 10') comprising at least one fluid inlet duct (41; 41') communicating with the fluid inlet chamber (43; 43') and an interface section (19; 19') at which the header tank (10; 10') is joined to the header plate (11; 11'), wherein the interface section (19; 19') has a hollow, substantially rectangular cross-section defined by a plurality of walls (10a, 10e, 10c, 10d; 10a', 10b', 10c', 10d') of the header tank (10; 10'). At least one flow deviating projection (51, 52; 51'), protruding into the fluid inlet chamber (43; 43'), is formed on at least one corner between adjacent walls of the header tank (10; 10') at the interface section (19; 19') thereof, said flow deviating projection (51, 52; 51') restricting fluid flow to at least one tube (31; 31') of the core (30; 30') adjacent to said corner.
