HEAT EXCHANGER FOR AUTOMOBILE

PROBLEM TO BE SOLVED: To provide a radiator capable of preventing stress concentration to a tube of an outermost end by uniforming temperatures of tubes while securing rigidity of the radiator itself. SOLUTION: In the heat exchanger for an automobile, a cooling air amount adjusting means 2 is provided between each side plate and the tube 13a of the outermost end for carrying out adjustment such that a cooling air amount passing between the side plate and the tube of the outermost end becomes less than cooling air amounts passing between other mutually adjacent tubes. The cooling air adjusting means is composed by a bent part 21 reducing an air passing area, formed by downwardly bending an air passing direction front side end of a fin 16 between the side plate and the tube of the outermost end into a substantially L-shape, so as to increase draft resistance of the cooling air amount passing between the side plate and the tube of the outermost end.
