The thermal technology is based on the characteristics of neodymium, vertical, too ^ ^ .. Α, /, compact and flexible and reliable. The heat dissipation problem caused by the performance improvement. 2) The rapid development of electronic technology, the high and high speed of electronic devices. Please refer to section-. A typical heat pipe 10 is composed of a shell u, a wick 12 (capillary structure) and sealed in The working fluid 13 in the tube is made up. The system of the heat pipe 10 is usually evacuated and filled with a suitable working fluid. The liquid-absorbing wick 12 that is close to the inner wall of the official is filled with the working fluid i 3 and sealed. One end of the heat pipe i 0 is a steaming section, a heating section 10a (heating section), and the other end is a condensing section 10b (cooling section). 'Insulation sections can be arranged between the evaporation section 10a and the condensation section 10b according to the needs of the application. When the heat pipe 10 evaporating section 10a is heated, the working fluid 13 in the liquid wick 12 evaporates and vaporizes to form steam 14, and the steam 14 flows to the condensation section 10b of the heat pipe 10 under a slight pressure difference, and condenses. It becomes working fluid 13 and emits heat 15, and working fluid 1 3 relies on wool. The action flows back to the evaporation section 10a along the wick 2 and in this cycle, the heat 15 is continuously transferred from the evaporation section 10a of the heat pipe 10 to the condensation section 10b, and is condensed by the section 10b. In the process of heat conduction, heat pipe 10 includes the following six interrelated main processes: 1233977 V. Description of the invention (2) (1) Heat s: 1 5 from the heat source through the heat pipe shell The wick 12 of the working fluid i 3 is transferred to the working fluid 1 3; (2) The working liquid 13 is evaporated on the liquid-vapor interface in the evaporation section 10a; (3) The vapor 14 flows from the evaporation section 10a to Condensing section 1 〇 乜; (4) Krypton gas 14 condenses on the gas-liquid interface in the condensing section 10b; (5) Hot set 15 passes from the gas-liquid interface through the wick 12, working liquid 13 and tube The shell 11 is transmitted to the cold source; (6) The condensed working fluid 13 is returned to the evaporation section 10a due to the capillary action in the wick 12. From the above six processes, it can be seen that the wick 12 is in the process (丨) and process (5) play an important role in heat conduction, in process (6) play a decisive role in the rapid return of condensed working fluid 1 3, so the wick 2 is very necessary for the normal and effective work of the heat pipe. # The liquid suction core 1 2 in the first technology is generally a wire mesh, grooved or twisted knot. It is easier to absorb the liquid. Manufacture and purchase screens with a fixed number of meshes in the market. Its materials-generally copper, stainless steel, and barbed wire, can be selected according to the compatibility of the working fluid of the heat pipe. # ㈣ After cleaning and necessary processing, it is rolled up. The required shape can be inserted into the heat pipe. The grooved wick is in the form of a car groove or a hoop groove. The axial groove is formed by extrusion and broaching; the m-direction groove is generally carved for convenience and processing. Threaded. The porosity of the sintered liquid absorbent is generally 40 to 50%, which is obtained by sintering a large amount of metal powder particles for filling.
