Abstract
A method for manufacturing a radiator including preparing, aligning, punching, bending, shearing and riveting, rotating, and removing processes is provided. The shearing, riveting, and rotating processes are repeated. A sheet metal is continuously punched to form a plurality of heat dissipation fins in a manufacturing machine, the heat dissipation fins are then orderly sheared, inserted into the metal base, and further fixed with the metal base by two-direction riveting. The radiator can thus be obtained in an automatic and faster process without unnecessary assembling steps with higher yield and reduced costs.

A method for manufacturing a radiator having a metal base and a plurality of heat dissipation fins, comprising:
- preparing a metal base and placing it on a manufacturing fixture of an aligning-and-moving mechanism of a manufacturing machine, wherein the metal base has a plurality of slots at the periphery of the metal base, a number of the slots is defined as Y, the manufacturing machine has a sheet metal;
- aligning and moving the manufacturing fixture and the metal base to a position under the sheet metal;
- punching two side-portions of the sheet metal to form a plurality of positioning holes, wherein the positioning holes of the sheet metal are spaced apart by equal distance, the sheet metal is positioned by inserting a locating pin into one of the positioning holes thereof, the sheet metal is continuously punched to form a plurality of heat dissipation fins, a number of the heat dissipation fins is defined as X;
- bending the heat dissipation fins downwards;
- shearing and riveting the sheet metal moved by the manufacturing machine, wherein when one of the heat dissipation fins is aligned with one of the slots, the heat dissipation fin is sheared and inserted into the slot by a shearing die of the manufacturing machine, a top surface and a bottom surface of the metal base at two sides of the slot are pressed by a riveting blade of the manufacturing machine so that a plastic deformation is formed on the metal base and two side-walls of the slot are tightened with two opposite surfaces of the heat dissipation fin;
- rotating the manufacturing fixture, wherein the metal base is rotated 1/Y circle;
- repeating the shearing and riveting for X−1 times, and repeating the rotating for Y−1 times, so that the rest of the heat dissipation fins of the sheet metal are orderly assembled with the Y−1 slots;
- and
- removing the metal base and the heat dissipation fins after assembled from the manufacturing fixture to obtain a radiator.
