Description
本發明關於一種熱管，尤指一種於蓋體上形成有通道之熱管。 The invention relates to a heat pipe, in particular to a heat pipe formed with a passage on a cover body.
散熱裝置與電子產品的發展息息相關。由於電子產品在運作時，電路中的電流會因阻抗的影響而產生不必要的熱能，如果這些熱能不能有效地排除而累積在電子產品內部的電子元件上，電子元件便有可能因為不斷升高的溫度而導致損壞。因此，散熱裝置的優劣影響電子產品的運作甚鉅。 Heat sinks are closely related to the development of electronic products. Since the current in the circuit generates unnecessary heat due to the influence of the impedance when the electronic product is in operation, if the thermal energy cannot be effectively eliminated and accumulated on the electronic components inside the electronic product, the electronic component may be raised because of the rising The temperature causes damage. Therefore, the advantages and disadvantages of the heat sink affect the operation of electronic products.
一般而言，許多散熱裝置中皆設置有熱管，用來將電子元件所產生的熱能傳導至散熱器，再由散熱器將熱能排出電子產品外部。熱管係由中空管體、毛細結構以及工作流體組成。於製造熱管時，先前技術係先將中空管體的一端密封，於中空管體中形成毛細結構，將工作流體自中空管體一端的開口填充於中空管體中，再將開口焊接密封。由於焊接密封與抽真空必須同時進行，作業難度較大，且生產效率較低。 In general, many heat sinks are provided with heat pipes for conducting the heat energy generated by the electronic components to the heat sink, and the heat sinks discharge the heat energy to the outside of the electronic products. The heat pipe is composed of a hollow pipe body, a capillary structure, and a working fluid. In the manufacture of the heat pipe, the prior art first seals one end of the hollow pipe body, forms a capillary structure in the hollow pipe body, fills the working fluid from the opening of one end of the hollow pipe body in the hollow pipe body, and then opens the opening. Welded seal. Since the welding seal and the vacuum must be carried out at the same time, the operation is difficult and the production efficiency is low.
本發明提供一種於蓋體上形成有通道之熱管，以解決上述之問題。 The invention provides a heat pipe formed with a passage on a cover body to solve the above problems.
根據一實施例，本發明之熱管包含一管體以及一蓋體。管體具有一中空腔室以及一開口。蓋體具有一通道。蓋體完全密封開口，使得中空腔室呈現真空狀態。在蓋體完全密封開口後，通道被管體遮蔽。 According to an embodiment, the heat pipe of the present invention comprises a tubular body and a cover. The tubular body has a hollow chamber and an opening. The cover has a passage. The cover completely seals the opening such that the hollow chamber assumes a vacuum. After the cover completely seals the opening, the passage is shielded by the tubular body.
綜上所述，由於蓋體上具有通道，因此本發明可在對管體之中空腔室進行抽真空時，使中空腔室中的氣體經由此通道排出管體。接著，使蓋體完全密封開口，即可使中空腔室呈現真空狀態。相較於先前技術，本發明不僅結構簡單且操作容易，可有效提升生產效率。 In summary, since the cover body has a passage, the present invention can discharge the gas in the hollow chamber through the passage when the cavity is evacuated in the tubular body. Then, the lid body is completely sealed to the opening, so that the hollow chamber is brought into a vacuum state. Compared with the prior art, the invention not only has a simple structure and is easy to operate, but also can effectively improve production efficiency.

請參閱第1圖，第1圖為根據本發明一實施例之熱管1的剖面示意圖。如第1圖所示，熱管1包含一管體10、一蓋體12、一毛細結構14以及一工作流體16。管體10具有一中空腔室100以及一開口102。管體10可由金屬(例如，鋁、銅等)、陶瓷、石墨、鑽石、其它高導熱率材料之組合(例如，共燒金屬、共燒陶瓷、複合材料等)或其它高導熱率材料製成。於此實施例中，管體10係為一體成型，但不以此為限。蓋體12具有一通道120。於此實施例中，通道120係呈L形，但不以此為限。毛細結構14形成於中空腔室100中，且工作流體16填充於中空腔室中100。毛細結構14用以增進工作流體16的散熱循環。於實際應用中，毛細結構14可為溝槽式毛細結構、多孔性毛細結構、網狀毛細結構、粉末燒結毛細結構或複合式毛細結構，視實際應用而定。上述之複合式毛細結構可由溝槽式毛細結構、多孔性毛細結構、網狀毛細結構與粉末燒結毛細結構中的至少兩種毛細結構組成。此外，工作流體16可為水或其它液體。 Please refer to FIG. 1. FIG. 1 is a schematic cross-sectional view of a heat pipe 1 according to an embodiment of the present invention. As shown in FIG. 1, the heat pipe 1 includes a pipe body 10, a cover body 12, a capillary structure 14, and a working fluid 16. The tube body 10 has a hollow chamber 100 and an opening 102. The tube body 10 can be made of a metal (eg, aluminum, copper, etc.), ceramic, graphite, diamond, other combinations of high thermal conductivity materials (eg, co-fired metal, co-fired ceramics, composite materials, etc.) or other high thermal conductivity materials. . In this embodiment, the tube body 10 is integrally formed, but is not limited thereto. The cover 12 has a passage 120. In this embodiment, the channel 120 is L-shaped, but is not limited thereto. The capillary structure 14 is formed in the hollow chamber 100, and the working fluid 16 is filled in the hollow chamber 100. The capillary structure 14 serves to enhance the heat dissipation cycle of the working fluid 16. In practical applications, the capillary structure 14 may be a grooved capillary structure, a porous capillary structure, a mesh capillary structure, a powder sintered capillary structure or a composite capillary structure, depending on the practical application. The composite capillary structure described above may be composed of at least two capillary structures of a grooved capillary structure, a porous capillary structure, a network capillary structure and a powder sintered capillary structure. Additionally, the working fluid 16 can be water or other liquid.
在對熱管1進行真空密封前，可先於管體10之中空腔室100中形成毛細結構14，且於管體10之中空腔室100中填充工作流體16。此外，亦可先於管體10之中空腔室100中形成毛細結構14，再於後續對熱管1進行抽真空時，一併將工作流體16填充於管體10之中空腔室100中。 Before the heat pipe 1 is vacuum sealed, the capillary structure 14 may be formed in the cavity 10 in the pipe body 10, and the working fluid 16 is filled in the cavity 100 in the pipe body 10. In addition, the capillary structure 14 may be formed in the hollow chamber 100 in the tubular body 10, and then the working fluid 16 may be filled in the hollow chamber 100 of the tubular body 10 when the heat pipe 1 is subsequently evacuated.
在對管體10之中空腔室100進行抽真空時，可使管體10之中空腔室100中的氣體經由蓋體12之通道120排出管體10。接著，使蓋體12完全密封管體10之開口102，即可使管體10之中空腔室100呈現真空狀態。在蓋體12完全密封管體10之開口102後，蓋體12之通道120即會被管體10遮蔽。需說明的是，在蓋體12完全密封管體10之開口102前，管體10之中空腔室100中的氣體皆可經由蓋體12之通道120順暢地排出管體10。藉此，可在蓋體12即將完全密封管體10之開口102時，有效避免些微氣體無法抽出而殘留於中空腔室100中。此外，本發明可預先於蓋體12周圍及/或管體10之開口102周圍塗佈密封物質(例如，樹脂、密封膠等)。在將蓋體12推入管體10之開口102而將開口102密封後，密封物質可進一步加強蓋體12與管體10之開口102間的真空密封性。 When the cavity 100 is evacuated in the tube body 10, the gas in the cavity 100 in the tube body 10 can be discharged out of the tube body 10 via the passage 120 of the lid body 12. Next, the lid body 12 is completely sealed with the opening 102 of the tubular body 10, so that the hollow chamber 100 in the tubular body 10 is in a vacuum state. After the cover 12 completely seals the opening 102 of the tubular body 10, the passage 120 of the cover 12 is shielded by the tubular body 10. It should be noted that before the cover 12 completely seals the opening 102 of the pipe body 10, the gas in the cavity 100 in the pipe body 10 can smoothly discharge the pipe body 10 through the passage 120 of the cover body 12. Thereby, when the lid body 12 is about to completely seal the opening 102 of the pipe body 10, it is possible to effectively prevent some of the micro gas from being extracted and remaining in the hollow chamber 100. Further, in the present invention, a sealing substance (for example, a resin, a sealant, or the like) may be applied in advance around the lid body 12 and/or around the opening 102 of the tube body 10. After the lid 12 is pushed into the opening 102 of the tubular body 10 to seal the opening 102, the sealing substance can further enhance the vacuum tightness between the lid 12 and the opening 102 of the tubular body 10.
請參閱第2圖，第2圖為根據本發明另一實施例之熱管1'的剖面示意圖。熱管1'與上述的熱管1的主要不同之處在於，熱管1'之蓋體12具有一外螺紋122，且熱管1'之管體10之開口102具有一內螺紋104。因此，此實施例係使蓋體12之外螺紋122與管體10之開口102之內螺紋104完全嚙合，進而使蓋體12以螺紋嚙合的方式完全密封開口102。同理，在蓋體12完全密封管體10之開口102後，蓋體12之通道120即會被管體10遮蔽。需說明的是，第2圖中與第1圖中所示相同標號的元件，其作用原理大致相同，在此不再贅述。 Please refer to FIG. 2, which is a cross-sectional view of a heat pipe 1' according to another embodiment of the present invention. The main difference between the heat pipe 1' and the heat pipe 1 described above is that the cover 12 of the heat pipe 1' has an external thread 122, and the opening 102 of the pipe body 10 of the heat pipe 1' has an internal thread 104. Thus, in this embodiment, the external threads 122 of the cover 12 are fully engaged with the internal threads 104 of the opening 102 of the tubular body 10, thereby allowing the cover 12 to completely seal the opening 102 in a threaded engagement. Similarly, after the cover 12 completely seals the opening 102 of the tubular body 10, the passage 120 of the cover 12 is shielded by the tubular body 10. It should be noted that the components of the same reference numerals as those of the first embodiment shown in FIG. 2 have substantially the same operation principle and will not be described again.
請參閱第3圖，第3圖為根據本發明另一實施例之熱管1"的剖面示意圖。熱管1"與上述的熱管1的主要不同之處在於，熱管1"之管體10另包含一下蓋18。如第3圖所示，下蓋18可由焊接、緊配或其它金屬加工方法組裝於管體10下方。換言之，管體10可由多個部件組成，其中此多個部件可由焊接、緊配或其它金屬加工成型方法組成管體10。需說明的是，第3圖中與第1圖中所示相同標號的元件，其作用原理大致相同，在此不再贅述。 Please refer to FIG. 3, which is a cross-sectional view of a heat pipe 1" according to another embodiment of the present invention. The main difference between the heat pipe 1" and the heat pipe 1 described above is that the pipe 10 of the heat pipe 1" further includes Cover 18. As shown in Fig. 3, the lower cover 18 can be assembled under the tubular body 10 by welding, fitting or other metal working methods. In other words, the tubular body 10 can be composed of a plurality of components, wherein the multiple components can be welded, tightly The pipe body 10 is formed by a matching or other metal working forming method. It should be noted that the components of the same reference numerals as those shown in FIG. 1 are substantially the same, and will not be described again.
請參閱第4圖，第4圖為根據本發明另一實施例之熱管1'''的剖面 示意圖。熱管1'''與上述的熱管1的主要不同之處在於，熱管1'''另包含複數個散熱鰭片20。如第4圖所示，散熱鰭片20係以放射狀的方式自管體10周圍延伸出。於此實施例中，散熱鰭片20與管體10係為一體成型，但不以此為限。於另一實施例中，散熱鰭片20亦可藉由焊接、卡合、黏合或其它固定方式與管體10結合。散熱鰭片可將管體10的熱量向外導出，以增進散熱效果。需說明的是，第4圖中與第1圖中所示相同標號的元件，其作用原理大致相同，在此不再贅述。 Please refer to FIG. 4, which is a cross section of a heat pipe 1"" according to another embodiment of the present invention. schematic diagram. The main difference between the heat pipe 1''' and the heat pipe 1 described above is that the heat pipe 1"' further includes a plurality of heat radiating fins 20. As shown in Fig. 4, the heat dissipating fins 20 extend from the periphery of the tube 10 in a radial manner. In this embodiment, the heat dissipation fins 20 and the tube body 10 are integrally formed, but not limited thereto. In another embodiment, the heat dissipation fins 20 can also be combined with the tube body 10 by soldering, snapping, bonding or other fixing means. The heat dissipation fins can heat the heat of the pipe body 10 to improve the heat dissipation effect. It should be noted that the components of the same reference numerals as those shown in FIG. 1 are substantially the same, and will not be described again.
綜上所述，由於蓋體上具有通道，因此本發明可在對管體之中空腔室進行抽真空時，使中空腔室中的氣體經由此通道排出管體。接著，使蓋體完全密封開口，即可使中空腔室呈現真空狀態。相較於先前技術，本發明不僅結構簡單且操作容易，可有效提升生產效率。 In summary, since the cover body has a passage, the present invention can discharge the gas in the hollow chamber through the passage when the cavity is evacuated in the tubular body. Then, the lid body is completely sealed to the opening, so that the hollow chamber is brought into a vacuum state. Compared with the prior art, the invention not only has a simple structure and is easy to operate, but also can effectively improve production efficiency.
