ABSTRACT:
The invention relates to a header tank structure for a heat exchanger formed by rounding a clad material (a header tank material) into a circular tube form, and the header tank structure eliminates occurrence of swollen portions around the connecting portion of the ends of the header tank, and displacement of the connecting surfaces from each other is reduced, thereby to provide the header tank structure having an improved quality of brazing the connecting surfaces of the ends.
The invention is, in a header tank structure for a heat exchanger formed by rounding a header tank material to bring the ends thereof into butting with each other and connecting them together by brazing, the header tank material having either one of the surfaces which becomes the outer surface of the header tank or both surfaces which become outer and inner surfaces of the header tank are being coated with a brazing material, and the ends of the header tank material are formed with inclined surfaces which are respectively inclined with respect to a direction of wall thickness, each with a portion of end edge surface being left there.
