Claims

[Claims for Utility Model Registration] A plurality of flat tubes each having an outer shape of a flat surface and an arcuate surface are arranged between a pair of mutually parallel header pipes with their flat surfaces perpendicular to the axial direction of the header pipes. In the heat exchanger in which fins are fixed between the flat tubes, the header pipe is divided into two by a plane parallel to the axial direction of the header pipe, and the divided edges of each divided member are joined and combined. Each of the divided members has slits extending from one of the divided edges in a direction orthogonal to the axial line so as to face each other, and the opposing slits form a long hole in the combined state. A heat exchanger characterized in that each of the flat tubes is fitted into the elongated hole, and the joints and the dividing edges of each of the fittings are welded.
