Abstract

PURPOSE: To facilitate brazing for corrugated fins of heat exchanger, by intermediately providing spacers between each of bends of meandering pipe adjacent to each other, when the tops of fins and the surface of pipe are brazed after the corrugated fins of slant type are inserted to be pinched with pressure between each of the straight parts of meandering pipe.
CONSTITUTION: The heat exchanger is installed in a jig, with corrugated fins 2 of slant type inserted between each of straight parts 21 of the meandering pipe 3, and spacers 20 having rigidity as equal as of bends 23 intermediately provided to the open parts. Then the heat exchanger is pinched with pressure between the upper and the lower supporting boards 9 and 8 of the jig. As a result, the corrugated fins 2 are also pinched with pressure by the straight parts 21 of the pipe. Since the amount of displacement of bends 23 and that of open parts are being made equal by the spacers 20 intermediately provided between each of them, the straight parts 21 of the pipe are pressed in parallel to each other and can pinch the corrugated fins uniformly. The tops of corrugated fins 2 and the surface of straight parts 21 of the pipe are closely contacted to each other, therefore, brazing can be performed in this condition.
