<p>A header tank structure of heat exchanger is provided to improve the durability of the header tank by the addition of the coupling groove. A header tank structure of heat exchanger comprises a header(11) which has flections(18) in both end part. The flection is curve-cut upward from the side in which a tube injection hole(13) is formed and has a plurality of taps(15). A tank(12) has a joint(19) which is combined with the flection where coupling grooves(16) is formed along the longitudinal direction.</p> |
