Description of the Invention: [Technical Field] The present invention relates to a casting and a method of manufacturing the same, and more particularly to a casting having a metal insert and a method of manufacturing the same. [Prior Art] A heat sink of a common electronic device is a close contact between a solid heat sink and an electronic component heat source, and then one end of a heat pipe is in contact with the heat sink surface, the heat pipe is a copper tube The inside is filled with water, and the heat sink absorbs heat and then conducts heat to the other end through the end of the heat pipe, and then dissipates heat to the atmosphere by a fan or other means. The embedded heat sink group commonly used in the industry first drills a hole in the heat sink, and the heat pipe plug is installed in the hole, and the heat pipe is formed at the end of the heat pipe to form a slender needle-like corner tip, such as only Inserting the heat sink drilling heat pipe will inevitably be completely tightly combined due to the tip of the corner, increasing the contact thermal resistance of the two and reducing the heat dissipation efficiency. In addition, as shown in FIG. 1A and FIG. 1B, some heat sinks 10 and the heat pipe 11 are combined by a cover plate 12 by riveting, welding, surface contact, embedding, etc., but the above method cannot avoid contact between the heat sink and the heat pipe. The phenomenon of excessive thermal resistance. In addition, for heat pipes of complex shapes, such as circular or extended heat pipes, it is difficult to machine holes in the heat sink, and the heat transfer efficiency cannot be fully realized. Referring to FIG. 1C, if the aluminum heat sink 10' is combined with the copper heat pipe 11' by casting, the heat sink 10' can be tightly wrapped around the outer peripheral surface of the heat pipe 11', thereby greatly reducing the difference between the two. Contact thermal resistance. Figures 1D to 1E show partial magnification photographs of different positions of the 201119770 ic. However, during the casting process, whether it is a semi-open sand mold, a wet sand mold, or a water-cooled cooling base at the bottom of the sand mold, or the other end of the heat pipe is cooled by cold water or even liquid nitrogen. When casting a heat sink, the temperature of the molten metal solution is too high, and the high-temperature heat energy cannot be immediately radiated to the outside, causing the heat pipe to burst and be damaged. Taking the aluminum heat sink 10' as an example, the molten aluminum liquid temperature is as high as 660 ° C. According to the currently used casting technology, the copper heat pipe 11' is bound to be in direct contact with the aluminum liquid due to the copper heat pipe 11'. The melting point of the copper heat pipe 11' itself, but because the liquid aluminum liquid is easily reacted with the copper material or because of the high solid solubility of the copper material in the aluminum, there is time in the casting cooling process to make the copper material be aluminum. Corrosion, such as heat pipe corrosion, Β, Β, and cause the copper heat pipe 11' to break. The molten metal liquid is filled into the heat pipe heat pipe 11', so that the heat pipe heat pipe 11' loses the heat dissipation effect. SUMMARY OF THE INVENTION The object of the present invention is to provide a casting in which a metal insert is cast in a casting manner, and at the same time, without requiring an additional heat sink for the mold or the metal insert, the casting does not occur to cause the metal insert to be produced by the existing one. A method of manufacturing a solid state into a liquid dissolution reaction while damaging the metal insert; another object of the present invention is to provide a casting having a metal insert. In order to achieve the above process, the present invention provides a method for manufacturing a casting having a metal insert, comprising: firstly providing a mold having a cavity, forming a separation layer on the surface of the metal insert, and fixing the metal insert to the metal insert; In the cavity, the cast body of the molten state is then injected into the cavity, and 201119770 soaks the metal insert in the body solution of the orthopedic body, and after cooling, forms the casting having the metal insert. The above separator may be formed by coating or spraying. The boron nitride may be pre-coated on the surface of the cavity before the step of injecting the molten body into the cavity. The above-mentioned metal insert may have a melting point different from that of the casting body, or the metal intrusion member may be pure copper, pure smear, pure magnesium, pure gold or sterling silver, and its shape may be a shape such as a shape, a rod shape, or a block shape. Each piece of the piece, including the surface of the insert, avoids the body of the prayer piece, and the invention provides a metal insert: a metal insert, an insulation layer, and The gold, wherein the separator is made of a ceramic material, is used for a solid-state conversion reaction into a liquid state, and a barrier layer covering the metal insert. The present invention is characterized in that the boron nitride material of the present invention has high insulating property, high thermal conductivity, high lubricity, high temperature resistance and non-sticking property (10), and forms a coating layer of a barrier layer on the surface of the gold melon. The insulation layer can exhibit at least the following qualities in casting 2: (1) having good compactness and stability, and having a reaction between the embedded component and the external medium, (1) has good heat transfer characteristics, can reduce the heat transfer performance of the soil-like melons after the surface treatment is reduced. 5 201119770 J [Embodiment] The embodiments of the present invention are described in detail below, and the drawings are a simplified schematic diagram, and the basic method or structure of the present invention is illustrated only by way of illustration.
