Invention: [Technical field of invention] Many 3C products are more computationally fast or more gorgeous in audio and video. At the same time, the heat generated by the 3C product itself is also greatly increased. The operational stability will be affected. Therefore, in order to effectively and smoothly remove the heat, the relevant heat dissipating component must have higher heat dissipation functionality, and thus the copper produced by the manufacturing method of the porous copper heat sink of the present invention is utilized. The heat sink has a heat sink that is superior to the existing heat sink components. [Prior Art] Conventionally, the conventional heat sink is manufactured by a method similar to an extruded aluminum alloy, a cutting alloy or a copper alloy, or a heat sink formed by stamping or welding a copper alloy. Fin type, and can only be processed into a single direction and sheet type heat sink products. Furthermore, the heat transfer performance of the aluminum alloy is inferior to that of the copper alloy, and the general shape can be formed by using the sowing type or the cutting method, but the heat sink product of a complicated shape cannot be completed, so even if it is The cost of using the cutting method to complete the required heat dissipation products is also high. Coupled with conventional technology products, it is not possible to effectively increase the heat dissipation surface area to increase the heat dissipation requirements. This shows that efficient and fast heat dissipation is extremely important for today's 3C products. Therefore, if a method can be provided to manufacture a heat dissipating component, the conventional heat dissipating component can increase the heat dissipating surface area, and can effectively improve the heat dissipating requirement, and is not limited by complicated shapes and cost-saving. Cooling products are quite helpful, making them more stable. SUMMARY OF THE INVENTION In view of the above-mentioned deficiencies of the prior art, the main object of the present invention is to provide a method for manufacturing a porous copper heat sink to solve the problem that the heat sink manufactured by the conventional technology cannot meet the heat dissipation requirements of today's 3C products. In order to achieve the above purpose, a porous copper heat sink of the present invention, 1291849, is foamed into a If-Gold, which replaces the conventional alloy as a heat-dissipating substrate, and the copper-gold core of the anode is placed through the electric pound forming process. The three-dimensional porous copper dispersion is placed on the foamed core of the cathode to form a bonding process, and the copper heat-dissipating core type and the copper base plate comprise a porous step. Heat sinks · The present invention is also a hot sheet. The porous copper dispersion liquid produced by the method for producing a copper heat release sheet: the anode and the cathode are required to be electrically cast. The foamed J type; Ϊ; Ϊ: copper sulphate. One. The shellfish can be used for at least the three-dimensional porous copper dispersion treatment of the self-twisting and PVC material, and is coated and anti-oxidized on the subsequent anti-oxidation surface to prevent the vertical I# multi-four-hole copper Surface of the heat sink [Embodiment] The surface of the copper-shaped heat sink is oxidized. The heat-generating components are mainly used to reduce the operating temperature. Among them, the large-sized pieces and the heat-dissipating sheets are used to reduce the heat transfer area, and the heat-cooling capacity is still strong. The invention has a lower thermal resistance and a higher cold. The invention is a multi-flowering; & is also conventionally known to manufacture a heat-dissipating product; the manufacturing method of the method is different from that of a foaming core type. And through the conductive, the foam forming process completes the plate and the three-dimensional porous steel is scattered;; === type, and - copper bottom shaped copper heat sink. This method is not only available due to the combination of the electric pounds and the two-dimensional porous copper heat sink, but also the effect and efficiency of the second embodiment of the preferred embodiment of the present invention.
