Description
本發明涉及一種熱管，尤係一種平板熱管。The invention relates to a heat pipe, in particular to a flat heat pipe.
平板熱管的工作原理與習知熱管相同，因其具有比習知熱管更大的熱傳導面積，且符合“輕、薄、短、小”的高實用價值，而被大量應用在具有較大散熱面的電子產品上。The working principle of the flat heat pipe is the same as that of the conventional heat pipe. Because it has a larger heat conduction area than the conventional heat pipe and meets the high practical value of “light, thin, short and small”, it is widely used in a large heat dissipation surface. On the electronics.
習知的平板熱管包括一金屬殼體及貼設於金屬殼體內表面各處的一連續的毛細結構。毛細結構圍設一蒸汽通道於其內。所述平板熱管沿其長度方向上可依次分為與熱源接觸的蒸發段及自蒸發段延伸的冷凝段。所述毛細結構包括位於蒸發段處的第一毛細結構及位於冷凝段處的第二毛細結構。所述第一毛細結構、第二毛細結構形狀及厚度相同。平板熱管工作時，第一毛細結構內的工作液體因受熱蒸發而進入蒸汽通道到達冷凝段放熱冷卻液化後經毛細力吸引而自第二毛細結構回流至第一毛細結構處。為了使第二毛細結構處的工作液體快速回流至第一毛細結構處而防止第一毛細結構乾燒，必須保證第一毛細結構具有高毛細力，第二毛細結構具有低毛細力。惟，由於第一毛細結構及第二毛細結構的形狀及厚度相同，因此，各處的毛細力相同，無法同時滿足熱管各處對第一毛細結構及第二毛細結構性能的不同要求，從而導致平板熱管的傳熱性能不佳。A conventional flat heat pipe includes a metal casing and a continuous capillary structure attached to the inner surface of the metal casing. The capillary structure encloses a steam passage therein. The flat heat pipe may be sequentially divided into an evaporation section in contact with the heat source and a condensation section extending from the evaporation section along the length direction thereof. The capillary structure includes a first capillary structure at the evaporation section and a second capillary structure at the condensation section. The first capillary structure and the second capillary structure have the same shape and thickness. When the flat heat pipe works, the working liquid in the first capillary structure enters the steam passage due to evaporation by heat, and reaches the condensation section. After the heat is cooled and liquefied, it is attracted by the capillary force and is returned from the second capillary structure to the first capillary structure. In order to quickly return the working liquid at the second capillary structure to the first capillary structure to prevent dry burning of the first capillary structure, it is necessary to ensure that the first capillary structure has a high capillary force and the second capillary structure has a low capillary force. However, since the shape and thickness of the first capillary structure and the second capillary structure are the same, the capillary force is the same everywhere, and the different requirements of the performance of the first capillary structure and the second capillary structure can not be satisfied at the same time, thereby resulting in The heat transfer performance of the flat heat pipe is not good.
有鑒於此，有必要提供一種具有良好傳熱性能的平板式熱管及所述平板熱管的製造方法。In view of the above, it is necessary to provide a flat heat pipe having good heat transfer performance and a method of manufacturing the flat heat pipe.
一種平板熱管，具有順序連接的蒸發段、傳熱段及冷凝段，所述平板熱管包括殼體及貼設於殼體上的毛細結構，所述毛細結構包括位於蒸發段的第一毛細結構、與第一毛細結構連接並自傳熱段延伸至冷凝段的第二毛細結構及與第一毛細結構及第二毛細結構連接且貫穿蒸發段、傳熱段及冷凝段的第三毛細結構，所述第一毛細結構的毛細力大於第三毛細結構的毛細力。A flat heat pipe having an evaporation section, a heat transfer section and a condensation section connected in series, the flat heat pipe comprising a casing and a capillary structure attached to the casing, the capillary structure comprising a first capillary structure located in the evaporation section, a second capillary structure coupled to the first capillary structure and extending from the heat transfer section to the condensation section and a third capillary structure coupled to the first capillary structure and the second capillary structure and extending through the evaporation section, the heat transfer section, and the condensation section, The capillary force of the first capillary structure is greater than the capillary force of the third capillary structure.
一種具有順序連接的蒸發段、傳熱段及冷凝段的平板熱管的製造方法，包括以下步驟：A method for manufacturing a flat heat pipe having an evaporation section, a heat transfer section and a condensation section which are sequentially connected, comprising the following steps:
提供一端具有開口的扁平的殼體；Providing a flat housing having an opening at one end;
提供一具有溝槽的模具，將所述模具放置於所述殼體內而使所述殼體的內表面對應熱管的傳熱段及冷凝段處在縱向方向上形成有溝槽狀的第二毛細結構；Providing a mold having a groove, the mold is placed in the casing such that an inner surface of the casing is formed with a groove-shaped second capillary in a longitudinal direction corresponding to a heat transfer section and a condensation section of the heat pipe structure;
提供多個金屬粉體，所述粉體燒結而形成位於熱管的蒸發段處的第一毛細結構；Providing a plurality of metal powders, the powder being sintered to form a first capillary structure at an evaporation section of the heat pipe;
提供多個金屬絲線，並將這些金屬絲線相互纏繞而形成所述第三毛細結構，所述第三毛細結構貫穿蒸發段、傳熱段及冷凝段，所述第三毛細結構的一端形成在第一毛細結構上、相對另一端形成在第二毛細結構上；Providing a plurality of metal wires, and winding the metal wires to each other to form the third capillary structure, the third capillary structure penetrating through the evaporation section, the heat transfer section and the condensation section, and one end of the third capillary structure is formed at the Formed on the second capillary structure on one capillary structure and opposite the other end;

與習知技術相比，平板熱管在使用時，因第一毛細結構的毛細力大於第三毛細結構的毛細力，收容在第三毛細結構內的工作液體在毛細力的牽引下，能夠快速的自第三毛細結構回流至第一毛細結構從而避免第一毛細結構乾燒，保障了平板熱管的工作性能。Compared with the prior art, when the flat heat pipe is used, the capillary force of the first capillary structure is greater than the capillary force of the third capillary structure, and the working liquid accommodated in the third capillary structure can be quickly pulled under the capillary force. The third capillary structure is reflowed to the first capillary structure to avoid dry burning of the first capillary structure, thereby ensuring the working performance of the flat heat pipe.
如圖1至圖3所示，為本發明第一實施例的平板熱管1。所述平板熱管1為縱長的管體，沿其長度方向依次為順序連接的一蒸發段11、一傳熱段13及一冷凝段15。所述平板熱管1包括一殼體30、貼設於殼體30內表面的毛細結構50及收容於毛細結構50內的工作液體（圖未示）。所述殼體30為內空且縱長的扁平管體，其各處深度相等且相對兩端密封。所述殼體30的橫截面呈跑道形。As shown in FIGS. 1 to 3, a flat heat pipe 1 according to a first embodiment of the present invention is shown. The flat heat pipe 1 is an elongated pipe body, and sequentially has an evaporation section 11, a heat transfer section 13 and a condensation section 15 which are sequentially connected along the longitudinal direction thereof. The flat heat pipe 1 includes a casing 30, a capillary structure 50 attached to the inner surface of the casing 30, and a working liquid (not shown) housed in the capillary structure 50. The housing 30 is an inner hollow and elongated flat tube body having equal depths and sealed at opposite ends. The housing 30 has a racetrack shape in cross section.
所述毛細結構50包括位於蒸發段11處的第一毛細結構51、與第一毛細結構51連接並自傳熱段13延伸至冷凝段15的一第二毛細結構53及與第一毛細結構51及第二毛細結構53連接且貫穿蒸發段11、傳熱段13及冷凝段15的一第三毛細結構55。所述第二毛細結構53的毛細力小於第一毛細結構51的毛細力而大於第三毛細結構55的毛細力。所述第二毛細結構53的孔隙率大於第一毛細結構51的孔隙率而小於第三毛細結構55的孔隙率。The capillary structure 50 includes a first capillary structure 51 at the evaporation section 11, a second capillary structure 53 connected to the first capillary structure 51 and extending from the heat transfer section 13 to the condensation section 15, and the first capillary structure 51 and The second capillary structure 53 is connected and extends through the evaporation section 11, the heat transfer section 13, and a third capillary structure 55 of the condensation section 15. The capillary force of the second capillary structure 53 is smaller than the capillary force of the first capillary structure 51 and larger than the capillary force of the third capillary structure 55. The porosity of the second capillary structure 53 is greater than the porosity of the first capillary structure 51 and less than the porosity of the third capillary structure 55.
所述第一毛細結構51為由金屬粉體燒結形成的跑道形環狀結構，其外表面緊密貼設並佈滿對應蒸發段11處殼體30的內表面。所述第二毛細結構53為形成於殼體30對應傳熱段13及冷凝段15處內表面的溝槽狀毛細結構，其接近蒸發段11的一端與第一毛細結構51連接。所述第二毛細結構53沿殼體30縱向的長度大於第一毛細結構51沿殼體30縱向的長度。所述第二毛細結構53包括多個凸齒531及位於凸齒531間的槽道533，每一凸齒531的寬度小於槽道533的寬度。The first capillary structure 51 is a racetrack-shaped annular structure formed by sintering metal powder, and the outer surface thereof is closely attached and covered with the inner surface of the casing 30 corresponding to the evaporation section 11. The second capillary structure 53 is a groove-like capillary structure formed on the inner surface of the heat transfer section 13 and the condensation section 15 of the casing 30, and one end of the evaporation section 11 is connected to the first capillary structure 51. The length of the second capillary structure 53 in the longitudinal direction of the housing 30 is greater than the length of the first capillary structure 51 in the longitudinal direction of the housing 30. The second capillary structure 53 includes a plurality of protruding teeth 531 and a channel 533 between the protruding teeth 531. The width of each of the protruding teeth 531 is smaller than the width of the channel 533.
所述第三毛細結構55形成於殼體30中部，由金屬絲線相互纏繞形成，其橫截面呈扁平橢圓形，其一側表面的一端貼設在第一毛細結構51的內表面、相對的另一端貼設在第二毛細結構53內表面且與第二毛細結構53之間形成微小孔隙，而其餘部分與第一毛細結構51及第二毛細結構53間隔設置。所述第一毛細結構51與第二毛細結構53沿殼體30縱向的長度之和等於第三毛細結構55沿殼體30縱向的長度。The third capillary structure 55 is formed in the middle of the housing 30, and is formed by winding a metal wire. The cross section is flat and elliptical, and one end of one surface is attached to the inner surface of the first capillary structure 51, and the opposite one is opposite. One end is attached to the inner surface of the second capillary structure 53 and forms a minute aperture with the second capillary structure 53, and the remaining portion is spaced apart from the first capillary structure 51 and the second capillary structure 53. The sum of the lengths of the first capillary structure 51 and the second capillary structure 53 in the longitudinal direction of the housing 30 is equal to the length of the third capillary structure 55 in the longitudinal direction of the housing 30.
如此，平板熱管1在使用時，因第三毛細結構55的孔隙率大於第一毛細結構51的孔隙率，在冷凝段15處放熱後冷卻的工作液體能夠快速的滲透進第三毛細結構55，又因第一毛細結構51的毛細力大於第三毛細結構55的毛細力，收容在第三毛細結構55內的工作液體在毛細力的牽引下，能夠快速的自第三毛細結構55回流至第一毛細結構51從而避免第一毛細結構51乾燒，保障了平板熱管1的工作性能。Thus, when the flat heat pipe 1 is in use, since the porosity of the third capillary structure 55 is greater than the porosity of the first capillary structure 51, the working liquid cooled after the heat release at the condensation section 15 can quickly penetrate into the third capillary structure 55, Moreover, since the capillary force of the first capillary structure 51 is greater than the capillary force of the third capillary structure 55, the working liquid accommodated in the third capillary structure 55 can quickly return from the third capillary structure 55 to the first under the traction of the capillary force. A capillary structure 51 thus avoids dry burning of the first capillary structure 51, thereby ensuring the performance of the flat heat pipe 1.
可以理解的，第一毛細結構51、第二毛細結構53及第三毛細結構55不局限於由本實施例中所述的材料製成，只要能夠滿足第二毛細結構53的毛細力小於第一毛細結構51的毛細力而大於第三毛細結構55的毛細力，第二毛細結構53的孔隙率大於第一毛細結構51的孔隙率而小於第三毛細結構55的孔隙率即可。It can be understood that the first capillary structure 51, the second capillary structure 53, and the third capillary structure 55 are not limited to the materials described in the embodiment, as long as the capillary force of the second capillary structure 53 can be satisfied to be smaller than the first capillary. The capillary force of the structure 51 is greater than the capillary force of the third capillary structure 55, and the porosity of the second capillary structure 53 is greater than the porosity of the first capillary structure 51 and smaller than the porosity of the third capillary structure 55.
