The capillary lion of the conventional heat pipe is a powder sinter on the inner wall of the metal shell, and the m capillary structure has the same light gap size and the void ratio is hooked. Where 'when the working medium absorbs heat in the evaporation section 40 to produce a phase change, the liquid volume rapidly expands into a vapor state (as indicated by the arrow in the figure) and quickly takes the heat source away from the beginning of the evaporation section, and quickly passes through the adiabatic section. (ΔΤ) almost no variation, the last steam in the condensation section _ plus the heat dissipation module and the exothermic generator acts as a cold thief liquid, by gravity (considering the operating angle effect or the inner side wall capillary structure of the Yang Li side evaporation section 4G, However, in practical applications, the three major areas of the above heat pipe have different characteristics depending on their individual functions, and the characteristics of the capillary structure are not the same. For example, the second figure shows that the capillary structure is empty.

Because of its small pore size and large number of nucleation, it is easy to cause bubble generation, increase vaporization and shorten heat pipe reaction. _. Key 5 (10) capillary structure 25 track _ and pore size The porosity and pore size of the capillary structure 24 in the evaporation section are mainly composed of powders with coarser particle distribution. Because of the large pore size, the working medium of condensation can be quickly returned from the condensation section to the adiabatic (4) and evaporation section. 40. The porosity and pore size of the capillary structure 26 in the condensing section 60 is the largest, mainly to increase the osmosis so that the read (10) slit can be connected and the fast gorge is transferred from the surface of the yang structure%' metal rupture 10 to the heat sink. In the module or in the atmosphere, for cooling purposes. However, the capillary structure of the heat pipe shown in the first or second figure has the same thickness in the evaporation section 4, the adiabatic section 50, and the condensation section. In accordance with the heat pipe evaporation section and the condensation section (4), the corresponding paste can be obtained. For example, the main ship of the heat pipe cold stage is to be dissipated by the vaporized red medium, and the corresponding demand is to quickly transfer heat to the heat pipe. The capillary structure layer has the function of reflowing the liquid working medium and increasing the heat transfer resistance between the working shells, thereby limiting the heat transfer performance of the heat pipe as a whole. [Invention] In view of this, It is necessary to provide a heat pipe with high heat transfer efficiency. - The heat f' includes a dense metal shell, which is filled with a red medium, and the inner wall of the shell is provided with a capillary structure layer, and the heat pipe includes a condensation section, The evaporation section and the adiabatic section between the two, the thickness of the capillary structure layer of the condensation section is smaller than the thickness of the capillary structure layer of the integral section, and the surface of the capillary structure layer corresponding to the heat insulation section is provided with the separation of the vapor-liquid splitting Compared with the prior art, the heat pipe has the following advantages: due to the capillary structure of the condensation section of the heat pipe 7 LS 1 1320093 The thickness of the resistance layer is thick and the condensed section is 崎 ^ ^ ^ _ _ _ small heat exchange is fast, Further, the overall scale efficiency of the heat pipe is improved. [Embodiment] The following is a detailed description of the preferred embodiment of the three-figure to the sixth (this fourth day), and the present invention is fully understood. The present invention only pays for the main technical characteristics of the (4) tube. Please refer to the Department of the Department of the Department of Hot #中实_轮彻. The Lin tube mainly contains a proper amount of working medium (not labeled) filled in the metal shell brain, the capillary structure layer and the metal shell (10). Lai _ sub-evaporation theory, seam Wei, condensation fine three ^ The heat pipe of the invention mainly through the powder in the gold bile shell 1 (_ wall sintering to form the gap size and void ratio from the stage 4_ to the sub-section gradually autumn The Maosaki structure is described as an example. However, the 'actual response', the hair _ capillary structure can also be any structure of the groove structure, the wire mesh structure and the composite structure. , _ segment _, condensing section _ three parts divided into sections of the hair domain structure, the heterogeneous layer, the condensation section capillary structure layer 260. wherein the thickness of the capillary structure layer 260 away from the direction of the thermal insulation section 5〇〇 Gradually reduce the closer to the end face, the thinner the capillary 260 is (even the shortest surface without the Maosaki structure), thereby accelerating the heat between the tube and the vaporized medium, and improving the thermal structure. The unequal _ shape is mainly produced by a copper mesh or the like in the form of a ruthenium-like shape when filling the powder. From the above, it can be seen that the fresh skein capillary layer 24q and the adiabatic segment capillary structure layer 250 have the same thickness. And the maximum thickness of the condensed section capillary structure layer 26 。. Please refer to the fourth figure The second embodiment of the heat pipe is characterized in that, on the basis of the first embodiment, the capillary structure layer of the heat pipe evaporation section is also set to a non-equal sectional shape, that is, the thickness thereof is gradually reduced from the direction of the 320093 adiabatic section 51〇. Small (but the thickness of the capillary structure layer at the sealing end is not limited thereto), the average thickness of the evaporated fine capillary structure layer 241 is larger than the fine average thickness of the condensing section 61 (10) capillary structure, and the thickness thereof substantially satisfies the rapid large-scale vaporization function of the working medium. Under the premise, make the thickness as thin as possible, tear the capillary structure layer (4) to test "by _ quantification, so as to increase the corresponding speed of the temperature, that is, the vaporization start speed", so that the heat pipe is in the state of rotation. The hairline structure of Chengfa section The layer 241 material cross-section is mainly manufactured by squashing in a manner of a jig or a copper mesh filled with the shape. From the above, the maximum thickness of the evaporating section capillary structure layer 241 and the condensing section capillary structure layer 261 of the heat pipe is known. The phase is the same as the thickness of the adiabatic segment capillary structure layer 251. Please refer to the fifth figure for the third embodiment of the heat f of the present invention. The difference between this embodiment and the second embodiment described above is that The capillary structure layer 262 of the heat pipe condensation surface and the capillary structure layer 242 of the evaporation section are uniform and have a certain thickness difference with the capillary structure of the heat insulation section 520, wherein the condensation section capillary structure layer 262 and the evaporation section capillary and structural layer The thickness of the crucible may be the same or different. It is also understood that the thickness of the capillary structure of the heat pipe condensation section in the above-described first embodiment can also be designed to be uniform and have a certain thickness difference from the thermal insulation capillary structure layer 260. Please refer to the sixth figure for the fourth embodiment of the heat pipe of the present invention. It is based on the second embodiment, m&5io. A thinner isolation layer is disposed between the liquid working medium and the vapor working medium, so as to overcome the reverse flow of the liquid and vapor working medium of the conventional heat pipe in the same space, thereby causing the shearing force, thereby causing shearing force And the transmission_transmission performance is reduced. It can be understood that the isolation layer 3 (8) used by the heat officer of the present invention can be appropriately extended to the evaporation section and the condensation section 610; the separation layer 3 can be a thin s shape of a film-like shape combined with the surface of the capillary structure layer, Fine mesh or other metal or non-metal separators. Similarly, the spacer layer 3 (8) may be added to the heat pipe of the first embodiment or the third embodiment. 1320093
