Abstract
A method for manufacturing a heat sink includes steps of: preparing a metallic belt; providing a spraying device for spraying a metallic coating layer on one surface of the metallic belt; providing a stamping device for blanking the metallic belt to form a heat-dissipating fin; and stacking a plurality of heat-dissipating fins to form the heat sink. In this way, the heat-dissipating area and efficiency of the heat sink can be increased. The stability and soldering ability of different materials can be improved. The present invention further provides a heat sink.
Claims14
A method for manufacturing a heat sink, including steps of:
- a) preparing a metallic belt;
- b) providing a spraying device for spraying a metallic coating layer on one surface of the metallic belt;
- c) providing a stamping device for blanking the metallic belt to form a heat-dissipating fin;
- and
- d) stacking a plurality of heat-dissipating fins to form the heat sink.
A heat sink, including a plurality of heat-dissipating fins, wherein one surface of each of the heat-dissipating fins is sprayed to form a metallic coating layer, at least one end of any one of the heat-dissipating fins is bent to have a fold, any two adjacent heat-dissipating fins are connected to each other by stacking the respective folds.
