A cylindrical header of a heat exchanger includes a central member, front-side and rear-side members extending longitudinally on front and rear sides of the central member to form front-side and rear-side spaces along with the central member. The central member has a first flange covering a front-side-member-first-end part and a rear-side-member-first-end part from outside when viewed in cross-section, and a second flange covering a front-side-member-second-end part and a rear-side-member-second-end part from outside when viewed in cross-section. The front-side member is joined to the central member with the front-side-member-first-end part facing an inner surface of the first flange, and the front-side-member-second-end part facing an inner surface of the second flange. The rear-side is joined to the central member with the rear-side-member-first-end part facing an inner surface of the first flange, and the rear-side-member-second-end part facing an inner surface of the second flange.

Provided is a cold-storage heat exchanger. The cold-storage heat exchanger includes a pair of header tanks, and tubes which are arranged in three rows with respect to the direction of the flow of air and connected at opposite sides thereof to the header tanks. A cold-storage medium is stored in the tubes that are disposed in a middle row, and refrigerant circulates through the tubes that are disposed in front and rear rows. Therefore, the cold-storage medium can effectively store cold-energy transferred from the refrigerant. When the engine of a vehicle is stopping, the cold-storage heat exchanger can discharge the cold-energy that has been stored into the passenger compartment of the vehicle, thus preventing the temperature in the passenger compartment from rapidly increasing, thereby creating pleasant air-conditioned conditions for a user, and minimizing the energy and time required to re-cool the passenger compartment.

The present invention relates to a heat exchanger that is disposed in an automotive air conditioner and provides cold air or hot air through heat exchange with air supplied by a fan and, more particularly, to an integrated module of an evaporator core and a heater core for an automotive air conditioner whereby the integrated module can simplify an automotive air conditioner by integrating an evaporator for cooling and a heater core for heating in the automotive air conditioner. According to the present invention, evaporator headers and heater headers are stacked and fixed in an integrated unit, so it is possible to simplify a facility. Accordingly, installation is easy and a volume can be reduced, as compared with the related art, whereby it is possible to reduce the weight of a vehicle.
