Description of the new type: [Technical field to which the new type belongs] In particular, a thermal conductivity that can improve the heat dissipation effect. The new type relates to a heat pipe (two) and a pipe (two). [Previous technology] The rapid development of the H3C technology industry in Mikou 'designs of various 3C electronic products continue to be improved and improved', but with the improvement of the efficiency of electronic products, the problem of internal heat dissipation of the product, so , Most electronic products are equipped with a diffuser set to remove the thermal energy inside the product. ...,
=電腦產品為例，若電子零組件所產生之熱能無法排除，則會導 致溫度逐漸升高，而使電腦過熱導致當機或無法運轉，因此一般的個 人電腦自配&有政熱片以及散熱風扇，散熱片係—表面具有許多籍片 =至屬片用於卩牛低電腦设備之溫度，而此散熱片在於增力u散熱面積， …、能之排除仍簡由周遭之氣流加轉除，·藉由風扇來吹拂散熱 片而將熱能帶走。然，上述之散熱片由於導熱之效率不佳，因此無法 在短％間内將熱自機设内排除；因此，遂發展出―先進的散熱技術— 熱導管。= Computer products as an example. If the thermal energy generated by electronic components cannot be eliminated, it will cause the temperature to gradually rise, and the computer will overheat and cause the machine to crash or fail to operate. Therefore, general personal computers are equipped with & Cooling fan, heat sink series-there are many pieces on the surface = to be used for yak low computer equipment temperature, and this heat sink is to increase the heat dissipation area u, can be excluded by the surrounding air Removal, · The heat is taken away by the fan to blow the heat sink. However, due to the poor heat conduction efficiency of the above-mentioned heat sinks, it is impossible to exclude heat from the machine within a short percentage; therefore, an “advanced heat dissipation technology” —heat pipe was developed.

The condensed working fluid will return to the heating end by capillary force, so it can continuously evaporate and Condensation to achieve the purpose of heat transfer. Because the velocity of the vapor phase in the thermal conductivity is much higher than the recirculation speed of the liquid-phase working fluid, the recirculation speed of the phase working fluid is the determinant of the heat conduction performance; the general thermal conductivity & Gravity is used to return liquid-phase working fluid. For example, the conventional thermal conductivity officer uses internal grooves or built-in metal mesh and copper powder to increase capillary force to accelerate the return of liquid-phase working fluid. speed. A conventional heat pipe structure using a metal mesh as a capillary structure is shown in the "picture", and includes a hollow tube body 100 and a metal mesh U0, and the metal mesh H0 is formed by a plurality of axial gold M278215. Top] ^ and multiple radial metal wires]] 2 staggered composition, metal mesh〗] 0 completely flat paste = the inner wall of the empty tube body 100, so as to increase the capillary force and speed up the backflow of the working fluid to achieve heat dissipation Good purpose. Ba Wu L'Although the above heat pipe has a good capillary force, but because the metal mesh 110 is completed and is on the inner wall of the hollow body 100, the radial metal and wire]] 2 will generate a backflow resistance which is subject to the backflow of the fluid. The situation 'makes the scale conduction effect worse, _ cooling effect [new content] 丨 fruit. Youyou 'This model proposes a heat pipe (2)' whose function is to improve the heat dissipation effect. In order to achieve the above purpose, a thinner work of this fresh pipe (2) 2 Ϊ If lines are staggered and combined ' When the wool-general net is placed into the tube body, the f-curved part and the tube body; the working fluid can reduce the backflow ambiguity through these gaps, and the liquid phase is accelerated by the capillary force. The resistance 'further enables the working fluid to reach the gap defined by the pipe body and accelerate the backflow by the heat-absorbing and heat-recycling cycle, and the curved portion 1 (^) as the metal mesh 20 of the capillary structure. The slave 10 and the pipe 10 are arranged inside the pipe body 10, and the pipe body 10 is a long-distance along the direction of the car. The inner part π contains an appropriate amount of working fluid (the hollow metal pipe in the hollow part 11 in the figure, the absorption / exothermic cycle of the hollow Zhao And perform the heat dissipation action. 7 If pure water or _ workflow, please refer to "Figure 3, 瞢 舻 1Λ 口"-ω 的 材 f-general copper with high material rate *, ⑧ M278215.resistant body iG_— Root Nozaki ··. After knowing the contact resistance and welding tails, etc., after reaching the required length, ^ closed end] 2 The method is taken as an example but is not limited to this; the pipe body ^ 12 Of course, the formation of Zhi 13 'is followed by the action of inserting capillary tissue. The other end is the movement of the opening. The word Kai Zhi 13 performs shrink tube sealing and heat conduction (II)! The capillary tissue is, line 21 And a plurality of radial metal wires 22 are staggered. This == consists of multiple copper materials with high conductivity. Through the metal mesh 2, = materials are mostly hot. Medium and metal are wound into a circular tube. In the present embodiment, a plurality of bent portions 23 recessed in the axial direction are provided, so that the metal mesh 20 has a portion, and a plurality of gaps 14 are defined between the inner wall of the pipe body 10 and the bent portion. The setting direction of 1 means that the working fluid in the liquid phase can pass through the second conductor (II). The flow resistance brought by line 21 is referred to as the axial metallicity of the wool, which can improve the heat pipe (II)]. The heat transfer force m is about 13. The speed end of the reflow is placed in the metal body II (two === from the body 4). The parts of the opening net 20 except the curved portion 23 are flatly attached to the pipe body ^, which is 10 after vacuuming Inject working fluid (* soil connection in the picture to complete the official body. Make the body (not shown in the figure), and seal the open end 13 to work in Elai, but the metal net works to make Gamma. Attachment; the tube body is combined with high-temperature sintering and moving ore. The gold 2G of the embodiment is made of wool with a plurality of axial gold lins 2 and a capillary structure 17_ can be stopped by this ... ~ p 刀 向 U / ;, Of course, in combination with multiple holes 14 of the metal mesh 20 == multiple gaps 14 formed by the pipe body 1 () _, the backflow resistance can be reduced, and the working fluid in the liquid phase can pass through the multiple gaps 14 and two. : < Mystery !, the second preferred embodiment can also be provided with multiple grooves on the inner wall of the tube body 10 M278215 15 'Ming with tea see "Figure 4" The working fluid in the hollow part can increase the maximum heat in the tube body by 10 °, 1 °, and 10 °. ΆSpeed up 'so that the working fluid can take away the above two embodiments when using, please refer to -The end is in contact with the heat source 30, while the other end is in contact with the cooling rack 40, the port 4 is in contact with the power-consuming chip, CPU or LCD, and the heat source 30 can be used as a heat sink. The natural convection heat dissipation provided, or the heat dissipation 40, can be a vacuum state within the heat sink, so the internal work; fluid heat V (2) 1 will come out when it comes into contact with the heat source 30, work The fluid evaporates from the liquid phase to the vapor phase, and this gas then passes through the heat pipe and the one end of the tube, so that one end of the heat absorption / exothermic cycle is completed, which can effectively bring the sharp = heat source 30 into contact. The heat pipe (2) touches, and the combination of the metal mesh 20 of the curved portion 23 is not as good as having a multi-body working flow through the capillary force provided by the metal mesh 20 to expedite backflow. Although the present invention has been described above with reference to the preferred embodiments, it is not. Anyone who is familiar with this technology is deviating from the spirit of this new model ^ 2 This new model ’retouching should still belong to the technical scope of this new model.
