Description of the Invention (i) The present invention provides a CPU heat sink and a manufacturing method thereof, in particular, a manufacturing method of a CPU heat sink with good heat dissipation effect and a long service life, and a finished product thereof. According to the current heat conduction type radiators on the market, generally 5 extrusion molding or injection molding manufacturing methods are used. When manufacturing this type of radiator, it is limited to the process of injection molding or extrusion molding. In consideration of the uniformity of the material and the ease of demolding, it is necessary to maintain a certain thickness and distance of the aluminum material; therefore, the thickness of the heat sink fins of the formed radiator is relatively thick and relatively the same On the heat-dissipating substrate, the number of heat-dissipating fins that can be formed is relatively small, and the total area formed is relatively small, resulting in a poor heat-dissipating effect and being unable to handle higher heat energy. As for the increasingly sophisticated information industry, the multiplication of functions and the continuous improvement of thermal energy are inevitable trends. Therefore, the radiators manufactured by traditional methods will increasingly fail to meet the needs of the industry. 15 In view of various shortcomings of the manufacturing method of the heat sink described in h, the inventor of the present case combines years of research and development experience, and considers that it can produce a CPU heat sink with good heat dissipation effect and long service life. "CPU heat sink and its manufacturing method" was produced. Based on the foregoing, a main object of the present invention is to provide a CPU heat sink capable of manufacturing a heat sink with a good heat dissipation effect and a long service life, and a manufacturing method thereof. The main feature of the present invention is to use injection molding technology to first form a branch of heat dissipation fins using metal powder and plastic powder as materials, and assemble the formed heat dissipation fins into a complete heat sink before feeding炉 中 进 __ 楚 4 百 _ This paper size applies to Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling this page) 5.
