Abstract
A method and a tool for manufacturing heat radiators are used to assemble a plurality of radiating fins to a heat transferring base. The method includes the steps of putting the radiating fins on the heat transferring base, putting blades between the radiating fins from at least one side of the heat transferring base, and pressing the blades to deform the heat transferring base to make the heat transferring base tightly fitted with the radiating fins. The tool includes a group of cutters and a pressing part. The cutter has blades having edges and pressing portions opposite to the edges. When the radiating fins are connected to the heat transferring base, the cutter may move between the radiating fins in a direction parallel to the heat transferring base. The pressing part is used for pressing the pressing portion to make the edges deform the heat transferring base, which forces the heat transferring base to be tightly fitted with the radiating fins.
