Abstract: A first header tank to which first heat exchange tubes of second and third exchange paths are connected and a second header tank to which second heat exchange tubes of a first exchange path are connected are provided at the left end of a condenser such that the former is located on the outer side of the latter. The upper end of the first header tank is located above the lower end of the second header tank. The first header tank separates gas and liquid from each other and stores the liquid. The first heat exchange tubes have, at their left ends, projecting portions extending leftward. Projecting portions of fins are disposed between the projecting portions of the adjacent first heat exchange tubes. The projecting portions of the first heat exchange tubes and the fins between the projecting portions of the first heat exchange tubes form a heat exchange section.

Abstract: In a condenser, an inlet connector to which a refrigerant is supplied is connected to a side wall of a first header. The inlet connector is disposed in the vicinity of an upper end portion of the first header, and is connected to the side wall of the first header through an inclined portion, which is inclined downwardly at a predetermined angle. In addition, when the refrigerant is supplied from the inlet connector into the interior of the first header, the refrigerant is supplied toward a substantially central region in the heightwise direction of the first header through the inclined portion. Therefore, the refrigerant can be made to flow substantially in a uniform manner with respect to a plurality of tubes, which are arranged in parallel in the heightwise direction of the first header, and heat exchange can be carried out.

The cylindrical portion has an inward protrusion protruding into a thermal storage material containing space, and the inward protrusion has a radially expanding engagement portion.

Abstract: A method of manufacturing a heat exchanger includes forming elongated holes in two connection walls among a plurality of connection walls to be laminated, and forming paired notches on a claw forming portion of the remaining connection wall facing the elongated holes. A longitudinally intermediate portion of the claw forming portion is pressed toward the other end to break the claw forming portion at the longitudinal center and bend the claw forming portion at the notches to thereby form two claws forming pieces and form bent portions at the distal ends of the claws forming pieces. The claws forming pieces are bent at the notches to form claws. Distal end portions of the claws are bent outward to form fold-back portions, which are engaged with the outer surface of the connection wall at the other end, whereby all the connection walls are provisionally fixed together.

Abstract: A cool storage material container is formed by brazing together peripheral edge portions of two aluminum plates. A cool storage material for storing cool is charged into a cool storage material accommodation space.
