PURPOSE: A heat exchanger is provided to prevent a bent portion located at the bottom of the outside of a tank combined portion of a header from being damaged by improving pressure endurance. CONSTITUTION: A heat exchanger includes a header tank(30), a header(31), a tank(33), tubes, and fins. The header tank is formed by assembling a header and a tank. The header tank forms a heat exchange media passage in which heat exchange media flow. The tubes are connected to the header tank forms a heat exchange media passage in which the heat exchange media flow. The fins are interposed between the tubs. A projection protruded inward is formed at a bent portion located at the outside bottom of a tank combined portion of the header. A recess corresponding to the projection is formed at a portion of the tank, which comes into contact with the projection. |
