請參閱圖1，本發明實施方式提供之一種熱管100包括第一管體10以及第二管體20，該第一管體10部分插入到該第二管體20中。Referring to FIG. 1 , a heat pipe 100 according to an embodiment of the present invention includes a first pipe body 10 and a second pipe body 20 , and the first pipe body 10 is partially inserted into the second pipe body 20 .
所述第一管體10為一封閉之長管狀結構，其由導熱性能良好之材料如黃銅、銅合金等一體製成。所述第一管體10內部形成一收容空間11，該收容空間11內封入有工作流體（圖未示）。所述第一管體10內還形成有毛細結構12，其用於吸附並回流所述工作流體，該毛細結構12可為溝槽結構、由銅、銀或鋁絲等金屬絲編織之編織網結構、由金屬粉末燒結形成之粉末燒結結構或上述三種結構之任意複合毛細結構等。所述第一管體10與其內之毛細結構12及工作流體等共同形成了一輔助熱管，該輔助熱管可為任意一種傳統之熱管。The first pipe body 10 is a closed long tubular structure which is integrally made of a material having good thermal conductivity such as brass, copper alloy or the like. A receiving space 11 is formed in the first pipe body 10, and a working fluid (not shown) is enclosed in the receiving space 11. A capillary structure 12 is also formed in the first tube body 10 for adsorbing and reflowing the working fluid. The capillary structure 12 may be a groove structure, a woven mesh woven from a metal wire such as copper, silver or aluminum wire. Structure, powder sintered structure formed by sintering of metal powder or any composite capillary structure of the above three structures. The first pipe body 10 together with the capillary structure 12 and the working fluid therein form an auxiliary heat pipe, and the auxiliary heat pipe can be any conventional heat pipe.
請接著參閱圖2以及圖3，所述第二管體20也為一長管狀，其直徑大於所述第一管體10之直徑。該第二管體20一端開口、另一端封閉，該第二管體20開口一端漸縮，以使開口之口徑與第一管體10之外徑相同。所述第二管體20內也設有工作流體，且內壁上形成有多個毛細結構21，該多個毛細結構21沿所述第二管體20之軸向延伸，並且相互之間均勻間隔，每兩個相鄰之毛細結構21之間形成蒸汽通道22，從而形成毛細結構21與蒸汽通道22相互交錯且獨立之結構。該蒸汽通道22直接延伸至第二管體20之內壁。所述毛細結構21為銅、銀或鋁絲等金屬粉末燒結形成之粉末燒結結構，其用於吸附並回流所述工作流體。Referring to FIG. 2 and FIG. 3, the second tubular body 20 is also a long tubular shape having a diameter larger than the diameter of the first tubular body 10. The second tubular body 20 is open at one end and closed at the other end. The open end of the second tubular body 20 is tapered so that the diameter of the opening is the same as the outer diameter of the first tubular body 10. A working fluid is also disposed in the second pipe body 20, and a plurality of capillary structures 21 are formed on the inner wall, and the plurality of capillary structures 21 extend along the axial direction of the second pipe body 20 and are evenly spaced from each other. At intervals, a vapor passage 22 is formed between each two adjacent capillary structures 21, thereby forming a structure in which the capillary structure 21 and the steam passage 22 are interleaved and independent. The steam passage 22 extends directly to the inner wall of the second tubular body 20. The capillary structure 21 is a powder sintered structure formed by sintering a metal powder such as copper, silver or aluminum wire for adsorbing and refluxing the working fluid.
所述第一管體10之一端從所述第二管體20之開口端插入到所述第二管體20中，並且抵接到所述第二管體20封閉端之內壁上，所述第一管體10之相對另一端則位於所述第二管體20之外部。在本實施例中，所述第二管體20內之毛細結構21大致呈等腰梯形，其外端面與內端面均呈圓弧形，且外端面沿第二管體20圓周方向之長度大於內端面沿第二管體20圓周方向之長度。該毛細結構21之外端面貼設於第二管體20之內表面上，而其內端面貼設於第一管體10之外表面上。所述每一蒸汽通道22形成於所述第二管體20之內表面、第一管體10之外表面及兩相鄰之毛細結構21之側表面之間。所述第二管體20之開口端與第一管體10進行焊接，從而將第一管體10與第二管體20及其內之毛細結構12、21、工作流體等組合成所述熱管100。One end of the first pipe body 10 is inserted into the second pipe body 20 from the open end of the second pipe body 20, and abuts against the inner wall of the closed end of the second pipe body 20, The opposite end of the first pipe body 10 is located outside the second pipe body 20. In this embodiment, the capillary structure 21 in the second tubular body 20 is substantially an isosceles trapezoid, and the outer end surface and the inner end surface are both arcuate, and the outer end surface is longer than the circumferential length of the second tubular body 20; The inner end face is along the length of the second pipe body 20 in the circumferential direction. The outer end surface of the capillary structure 21 is attached to the inner surface of the second pipe body 20, and the inner end surface thereof is attached to the outer surface of the first pipe body 10. Each of the steam passages 22 is formed between an inner surface of the second tubular body 20, an outer surface of the first tubular body 10, and a side surface of two adjacent capillary structures 21. The open end of the second pipe body 20 is welded to the first pipe body 10, thereby combining the first pipe body 10 and the second pipe body 20 and the capillary structures 12, 21, working fluids and the like therein into the heat pipe. 100.
在使用時，所述第一管體10從所述第二管體20延伸出來之一端作為熱管100之吸熱段，所述第二管體20作為熱管100之放熱段。根據Q=CM△T（Q為熱量，C為比熱，M為品質，△T為溫差）可知，當品質M增加，熱量Q也會增加，由於較細之第一管體10外面增加一較粗之第二管體20，可增加了熱管100之品質，從而提升了熱管100整體之換熱量，提高熱管100之傳熱性能。另外，由於所述第二管體20之毛細結構21和蒸汽通道22相互交錯且獨立，使得工作流體從每個毛細結構21中蒸發出來後，可以分別沿著臨近之蒸汽通道22流動，避免了蒸汽相互間之干涉，減少了流動阻力。而且由於第二管體20內之蒸汽通道22延伸至第二管體20之管壁，因此，工作時蒸汽可直接與第二管體20之管壁接觸，藉由管壁放熱，降低了熱管100之蒸汽通道22到管壁之熱阻，提升了傳熱性能。避免了傳統熱管結構之蒸氣通道被毛細結構包含，蒸汽到管壁之間熱阻較大之問題。In use, one end of the first tubular body 10 extending from the second tubular body 20 serves as an endothermic section of the heat pipe 100, and the second tubular body 20 serves as a heat releasing section of the heat pipe 100. According to Q=CM△T (Q is heat, C is specific heat, M is quality, ΔT is temperature difference), it can be seen that when the quality M increases, the heat Q also increases, due to the increase of the outer surface of the thinner first pipe 10 The thick second pipe body 20 can increase the quality of the heat pipe 100, thereby improving the overall heat exchange amount of the heat pipe 100 and improving the heat transfer performance of the heat pipe 100. In addition, since the capillary structure 21 and the steam passage 22 of the second pipe body 20 are mutually staggered and independent, the working fluid can be evaporated from each of the capillary structures 21, and can be respectively flowed along the adjacent steam passages 22, thereby avoiding The mutual interference of steam reduces the flow resistance. Moreover, since the steam passage 22 in the second pipe body 20 extends to the pipe wall of the second pipe body 20, the steam can directly contact the pipe wall of the second pipe body 20 during operation, and the heat pipe is lowered by releasing heat from the pipe wall. The thermal resistance of the steam passage 22 of the 100 to the pipe wall improves the heat transfer performance. The problem that the vapor passage of the conventional heat pipe structure is contained by the capillary structure and the heat resistance between the steam and the pipe wall is large is avoided.
