平チユーブ。[Claims for Utility Model Registration] (1) A flat tube for a heat exchanger, which is formed by bending a band plate into a flat cylindrical shape and soldering its ends to each other to form a cooling water flow passage inside. One-side notches and one-side protrusions are alternately formed on one side of the strip, and another shape corresponding to the one-side notch is formed on the other side of the strip plate at a position opposite to the one-side notch. forming a side protrusion; forming a second side notch having a shape corresponding to the one side protrusion at a position opposite to the one side protrusion; and aligning the one side protrusion and the other side protrusion in the same direction. bent to form a stirring protrusion, and the stirring protrusion faces inside the cooling water flow path;
The one side protrusion and the other side protrusion are inserted and bent inside the other side notch and the edge of the one side notch, respectively, and the one side and the other side of the strip plate are overlapped. A flat tube for a heat exchanger, characterized in that parts are brazed together and integrally molded. (2) The flat tube for a heat exchanger according to claim 1, wherein cuts of a predetermined length are formed on the extensions of both sides of the protrusion on one side and the protrusion on the other side.
