Description of the invention: [Technical field of the invention] The present invention relates to a heat conduction device, in particular, a prior art. [The heat pipe has a small volume, can rapidly transport a large amount of heat energy, has a light structure, and does not require an external force, Long life, low thermal resistance, and long-distance ^ ^ life' meet the needs of current computer cooling modules, so it is widely used = cooling problem. The basic structure is that the inner wall of the closed pipe is easy to absorb the capillary structure layer of the working fluid, and the central space is hollow. The sealed pipe is filled with the working fluid corresponding to the pores of the capillary structure layer. The reimbursement officer can be divided into three sections: the evaporation section, the adiabatic section and the cooling section according to the functional positions such as heat absorption or heat dissipation. The working principle of the above heat pipe is: a saturated working medium in the capillary structure of the tomb, absorbing the heat of the external heat source. = hair, because the pressure difference generated by the steam causes the steam to move quickly to the cooling section. The & steam releases heat in the cooling section and cools and condenses into a liquid. At this time, the work of condensation = the body is absorbed in the capillary structure of the cooling section, due to The cooling section passes through the absolute section: the pressure difference between the capillary tubes of the evaporation section is returned to the cooling section. The movement of the above working fluid and the returning process are cyclically operated, so that the evaporation section continuously transmits heat to the cooling section continuously. ^ 1 See The functions of the three sections of the heat pipe are different, and in order to give full play to the respective functions of the three sections of the heat pipe, the heat pipe is conveyed " The structure should meet the different needs of industry to this end ^ ^ 6 1289655 I 'in efforts to improve. [Summary of the Invention] There is a sweetness in this, there must be also - a kind of heat A, ^. eight heat pipe with better heat transfer performance. The metal pipe body is along the length of the pipe body as the body of the insulation section; the right amount of work; the section, the condensation section and the two and the capillary structure are disposed in the "two inlets in the sealed chamber; Ns , is inside the s body and fills the cavity corresponding to the evaporation section to 'and at least corresponds to the adiabatic section formed with a steam passage. The capillary structure of the heat pipe and the conventional heat pipe is filled, right:: has the following advantages: At the evaporation section, γ, , , , | enhances the heat absorption, #曰, and degree of the heat pipe evaporation section, and can increase the reflow capillary force to increase the speed of the condensed liquid, thereby greatly improving the overall heat transfer performance of the heat pipe. Embodiments of the present invention will be further described with reference to the following drawings. Fig. 1 and Fig. 2 'Fig. 1 is a longitudinal cross-sectional view of a first embodiment of a heat pipe of the present invention, a second transverse cross-sectional view of the π_π portion of Fig. 1 , and Fig. 2 is a ΠΚ [Ι1 portion of Fig. 1 Horizontal cross section view. The heat pipe comprises a pipe body 10 having a sealed chamber, the inner wall surface of which is smooth or provided with micro-grooves, and the pipe body 10 is provided with a capillary structure 2〇, which is other than the capillary structure 2〇. The jade room is the steaming channel 30, and the inside of the pipe body 1 is sealed with an appropriate amount of working fluid (not shown) and can be appropriately pumped to a certain degree of vacuum. The pipe body 10 can be divided into an evaporation section 4, a condensation section 60, and an adiabatic section 5〇 between the two sections along the length of the pipe body according to the function of its respective sections. 7 1289655 , 'Understandably' the support of the heat pipe may be a plurality of rib-shaped support members 80a extending along the circumferential surface of the insulation layer 70 and the pipe wall of the pipe body 1Q toward the length of the heat pipe as shown in FIG. 4a. Or a plurality of hollow tubular support members 80b as shown in Fig. 4Bm. Referring to Figure 5, there is shown a longitudinal cross-sectional view of a second embodiment of the heat pipe of the present invention. This embodiment differs from the first embodiment in that the heat pipe evaporation section 4〇a is located in the middle of the body l〇a, and the condensation section 6〇a has two and is located at both ends of the heat pipe, the burst section 40a and the two condensation section 6 There are two thermal insulation sections 5〇a between 〇a. A guide angle 23 is provided between the filled capillary structure 2〇a of the condensing section 60a and the unfilled capillary structure. Referring to Figure 6, there is shown a longitudinal section to a third embodiment of the heat pipe of the present invention. The difference between this embodiment and the second embodiment is that the heat pipe is bent at both ends - the heat pipe is generally U-shaped, that is, the two condensation sections 6 〇 b are parallel and perpendicular to the evaporation section 4 〇 b, and an adiabatic section 5 〇 b is located at the corners on both sides of the evaporation section 4〇b. It can also be understood that the capillary structure in the above embodiments of the present invention is located at the center of the heat pipe except for the filling, and the capillary structure can also be disposed along the inner wall of the heat official; the heat pipe can also be flattened. Flat, especially the evaporation section is flat. The heat pipe of the present invention having the above characteristics, because the capillary structure of the evaporation section is filled, is advantageous for improving the heat absorption performance of the evaporation section of the heat pipe, increasing the evaporation speed, and increasing the reflow capillary force to increase the reflux speed of the condensed liquid, thereby The overall heat transfer performance of the heat pipe is greatly improved. In summary, the present invention complies with the requirements of the invention patent, and is proposed according to law.
