Description of the invention (1) [Field of the invention] The present invention provides a method for die-casting or casting molding of thermal superconducting heat-conducting blocks, sheets, and covers, and in particular, it relates to a heat-conducting superconductor, a body having high heat transfer properties. A method of combining a thermal block or heat sink with a metal with good thermal conductivity properties to improve the thermal conductivity of the thermal block, sheet, and cover, and is suitable for any place that requires rapid heat transfer and heat dissipation from the medium, or provides better heat dissipation. Effector.

[Background of the Invention] At present, most of the heat dissipation devices used in the industry for computer central processing units (CPUs) or high-heat source products are aluminum heat sinks with high heat transfer efficiency (for example, Taiwan Announcement No. 4 5 9 4 6 9 The heat sink manufactured in the patent case) 's base is in contact with a heat source to absorb and transfer heat to the fins of the heat sink, and then use a fan to blow out cold air to remove the heat from the heat sink.

Since the high heat generated by today's high-efficiency CPUs is not as fast as conventional aluminum heat sinks, it can be quickly conducted and eliminated. Therefore, the use of copper metal that is about twice as efficient as I Lu metal to conduct heat from the CPU is another An option; however, the density of aluminum metal is about 2.7g / cm3, and the density of copper metal is 8.93g / cm3 (the copper metal of the same volume weighs about three times the weight of aluminum metal), so if made entirely of copper metal The heat sink will not be able to pass the ground test due to the weight of copper, or the motherboard will be deformed after being installed on the motherboard for too long. At present, the so-called aluminum heat sink with a copper bottom on the market uses a forging or welding technique to embed a pre-formed copper plate on the

Page 4 535487 V. Description of the invention (2) Base surface of aluminum heat sink; Taiwan Patent Bulletin No. 4 5 9 4 6 9 also belongs to the design of embedding copper plate in aluminum heat sink. Although a small thickness copper plate embedded in an aluminum heat sink has the effect of improving the thermal conductivity under lighter weight conditions, if an object with higher thermal conductivity can be combined with a thermal block or sheet such as a metal material And cover body, can further improve the thermal conductivity and heat dissipation performance of the thermal block, sheet, cover body; but traditionally limited by technical reasons, it does not provide effective objects and metals with high thermal conductivity. Material combination method. [Comprehensive description of creation] The main purpose of the present invention is to provide a die-casting or casting molding method for thermally superconducting blocks, sheets, and covers. The metal is combined with the two, and can be further formed into a thermal block, a thermal sheet or a thermal cover to be used as a heat conduction medium between a heat source and a heat dissipation element, or directly as a heat conduction and heat dissipation element. A secondary object of the present invention is to provide a die-casting or casting method for thermally superconducting heat-conducting block, sheet, and cover. The heat-conducting block, sheet, and cover made by the die-casting or casting method have more excellent properties. Thermal conductivity, so it is very suitable for connecting between components that need to conduct heat, according to the high efficiency of heat conduction. Based on this, the die-casting or casting molding method of the thermal superconducting heat-conducting block, sheet and cover provided in this creation must first select a heat-conducting super-conductor and body with a melting point higher than the melting point of the die-casting or casting metal. according to

535487 V. Description of the invention (3) After processing and bending, it is placed in the die-casting or casting mold, and then the molten metal liquid is placed in the die-casting or casting-molding mold and subjected to die-casting or casting molding, and cooled after being demolded. Molded to complete the finished product. In conjunction with the following drawings, other purposes and functions of this creation are further explained.

I [Embodiment Description] Referring to the flowchart of the first figure, the method for die casting or casting of the thermal superconducting block, sheet, and cover provided by the present invention includes the following steps: a. Selecting a thermally conductive superconducting block The pipe and the body 2 have a melting point higher than that of the die-cast or cast metal 11. b. The heat-conducting superconduit and the body 2 are processed and bent as required. c. Place the heat-conducting superconduit and body 2 into a die-casting or casting mold. d. Put the molten metal liquid into the die casting or casting mold and apply die casting or casting molding. e. After demoulding, it is cooled and formed to complete the finished product, that is, a thermal superconducting block, sheet and cover 1 are formed. The thermally conductive superconducting tubes and systems adopt metal tubes (such as copper, metal or other metal tubes) that can be bent or deformed freely, and the inside of the tubes or tubes has been filled or contains materials with high-speed thermal conductivity, such as : 1. Inorganic high-temperature superconducting compound materials, such as: yttrium barium copper oxide (YBCO) superconducting materials, samarium barium calcium copper oxide (TBCCO) superconducting materials

535487 V. Description of the invention (4) material, HBCCO superconducting material, _Total I bow copper oxy compound (BSCCO) superconducting material, or other inorganic superconducting materials. 2. Organic superconducting materials' such as pure water or other organic superconducting materials. 3. Other materials that can achieve high-speed thermal conductivity.

The two ends of the tube and the body are processed and closed to prevent the thermally conductive material from leaking out of the tube body. The metal tube and the body and the thermally conductive material contained in the metal tube and the body form a thermally conductive superconducting tube and body. The principle of inorganic south superconducting materials is based on the use of high-speed vibration and friction generated by molecules in the tube and the body when they are heated, so that heat can be rapidly transferred in a wavy manner. Organic high-temperature superconducting materials, the principles of which are applied, are The metal tube and the liquid molecules in the body are used for rapid heat transfer due to the phase change that occurs when the molecules of the body are heated. Because the transmission speed is very fast, they are called "heat-conducting super-conductors and bodies." The transmission time of the cold end is very short, so the temperature difference between the hot end and the cold end is small, which can achieve the best thermal conductivity. It has been confirmed by experiments that the heat transfer rate is about five times that of copper, and more than ten times faster than that of ordinary aluminum metals.

According to the method of the present invention, as shown in the second figure, the heat-conducting superconducting tube and the body 2 can be first bent into a bent shape, and then the heat-conducting superconducting tube and the body 2 can be put into a die-casting or casting mold, and then Molten metal 1 1 is die-cast or casted into the shape of a block, sheet, or machine / equipment to cover the heat-conducting superconducting tube and body 2 in the metal 11 to form a thermal superconducting block, sheet, Cover body 1. In this way, when the metal block is in contact with the heat source, the heat can be quickly conducted to other parts of the metal through the heat-conducting superconducting tube 2 to improve the heat conduction efficiency of the heat-conducting block, sheet, and cover.
