[Field of Invention]

The present invention provides-, method ', and especially-a method for manufacturing a thermal superconducting block, a sheet of superconducting tube, and a body by electroplating using J. The surface of the plating should be t! Materials are combined with heat transfer; to produce thermally conductive superconductors, they can use lower-melting-point metal tubes to discriminate precise thermal superconducting blocks, reduce manufacturing costs, and can produce more [Background of the Invention] The current industry is targeting ^ products The heat dissipation device used is a brain central processing unit (CM) or a high heat source heat sink (for example, Taiwan L = is a material with high heat transfer efficiency ^ ^ + Bow Publication No. 45 946 9) 1 Ke body) The base is in contact with the scattered fins of 埶% * Τ I w, and the wind is used to absorb and transfer heat to the heat sink. Eight fans of cold air remove the heat on the heat sink. Due to the high heat generated by today's high-efficiency CPUs, it is no longer common. The material heat sink can quickly conduct and eliminate, a. The use of thermal conductivity, rate, and metal is about high. Twice as much copper metal to conduct heat from the CPU is another alternative; however, the density of aluminum metal is about 2.7g / cm3, and the density of copper metal is 8.9g / cm3 (the weight of copper metal of the same volume) It is about three times as much as aluminum metal). Therefore, if the heat sink is made entirely of copper metal, the weight of copper cannot pass the ground test or the motherboard is 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 is a method of forging or welding that embeds a pre-formed copper plate on the bottom surface of the base of the heat sink in Taiwan; Taiwan Patent Bulletin No. 4 5 9 4 6 9 Also

The heat conduction method must be used for die casting and heat conduction. The superconductor using high shielding must be pressed. Tube: The conduction performance caused by the body is limited to the superconducting block and sheet of the car. The lack of the present invention is further added to the copper plate under the aluminum material to enhance the thermal conductivity. The combination of the material and the nature of the material is further advanced. Warmly forming metal, or combining tubes together, so it must be affected in the process of being higher than metal, which is the design of this product's manufacturing cost hot sheet. Embedded in the performance of the aluminum material, the material is made of a machine or a machine. Application 9 1 1 0 6 0 84 in this case is missing. A common feature, the cover body, the combination of the other is the block, sheet, cover melting and heat transfer using powder metallurgy and forming a heat transfer option to create dazzling points, and must consider whether temperature and pressure will affect heat transfer The yield rate is lower, because it is more south, and there is no heat sink. But if you can have a more heat sink, or a shell directly, it will be more clear that the previous applications are before the settlement, that is, Li Tong lies in the same. However, whether it is a body combination, its technology of superconducting catheter one will convert gold nuggets and sheets to thermally conductive superconductors, which can change the temperature and force of a few nanometers. What kind of combination is put into the metal material must be the material of the tube and the high metal body in the thermal range of the dense heat is the aim of these previous applications in the manufacturing process improvements.

The metal tube, the body and the heat-conducting material contained in the metal tube and the body constitute a heat-conducting superconducting tube and a body; the above-mentioned principle of the application of the inorganic high-superconducting material uses the high-speed vibration generated when the molecules in the tube and the body are heated. And friction to allow rapid heat transfer in a fluctuating manner. Organic south temperature superconducting materials, the principle of which is applied, is based on the use of phase changes generated when the molecules of the liquid in the metal tube and the body are heated to transfer heat quickly. It ’s fast, so it is called “heat-conducting super-conduit and body”, and because the heat-conducting super-conduit and body transfer time from the hot end to the cold end is very short, the temperature difference between the hot end and the cold end is very small, which can achieve the best heat conduction effect. . 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. With the aforementioned method of the present invention, it is possible to bend a metal tube or a body into a bent shape or other three-dimensional shape, and then connect a single or multiple heat-conducting superconducting tubes and bodies to a cathode of a direct current and put metal ions into them. And then direct current is applied to make the metal ions in the electrolyte deposit and adhere to the surface of the heat-conducting superconducting tube 1 to form metal blocks and sheets 2. The metal blocks and sheets can be cut according to the required shape Or other processing.

The thermal superconducting thermal block and sheet made by the method of the present invention are mainly used to conduct heat from a heat source to another heat dissipation element to improve thermal conduction efficiency; for example, it can transfer the thermal superconducting thermal block One end of the sheet is in contact with the heat source, while the other end of the sheet is in contact with the heat sink or the case to conduct heat to the more easily radiated components and cooperate with the fan to dissipate the heat.
