熱管 Heat pipe

本發明涉及一種熱管，尤其係一種具有編織毛細結構的熱管。 The present invention relates to a heat pipe, and more particularly to a heat pipe having a woven capillary structure.

熱管係一種具有高熱傳能力、快速傳熱及高熱傳導率的熱傳組件，其不僅可傳遞大量的熱，而且不消耗電力，因而廣受散熱市場的需求。目前的熱管管體內壁皆設有毛細結構(wick structure)，該毛細結構可以係具有毛細管作用的編織網等，可便於熱管內工作流體(working fluid)的傳輸。隨著電子產品的輕薄化，其散熱需求不斷提高，使得超薄熱管毛細結構的設計方式成為評估電子產品散熱性能好壞的關鍵。 The heat pipe is a heat transfer component with high heat transfer capability, rapid heat transfer and high thermal conductivity, which not only can transfer a large amount of heat, but also consumes no power, and thus is widely required by the heat dissipation market. The inner wall of the current heat pipe is provided with a wick structure, which may be a woven mesh having a capillary action, etc., which facilitates the transfer of a working fluid in the heat pipe. With the thinning and thinning of electronic products, the heat dissipation requirements are constantly increasing, making the design of ultra-thin heat pipe capillary structure the key to evaluating the heat dissipation performance of electronic products.

對於具有編織毛細結構的熱管，業界傳統方法將該毛細結構設計為縱橫垂直交錯編織的狀態，此種毛細結構在縱向方向上傳導工作流體的效率一般，只能滿足低功率熱管的需求。 For a heat pipe having a woven capillary structure, the conventional method in the industry designs the capillary structure into a state of vertical and horizontal vertical interlacing, and the efficiency of the capillary structure for conducting the working fluid in the longitudinal direction is generally sufficient to meet the demand of the low-power heat pipe.

有鑒於此，有必要提供一種具有高熱傳導效率的熱管。 In view of this, it is necessary to provide a heat pipe having high heat transfer efficiency.

一種熱管，包括一管體及設於管體內的至少一毛細結構，該至少一層毛細結構包括編織而成的多個網格，該至少一層毛細結構的網格呈菱形，每一菱形網格具有相對的兩第一夾角，所述兩第一夾角小於90度。 A heat pipe comprising a tube body and at least one capillary structure disposed in the tube body, the at least one capillary structure comprising a plurality of woven meshes, the mesh of the at least one capillary structure being rhombic, each diamond mesh having The two first angles are opposite to each other, and the two first angles are less than 90 degrees.

與現有技術相比，上述熱管至少將一層毛細結構的網格設置為菱形，管體內的工作流體沿網格的邊線流動時，路徑由斜邊取代傳統方形網格的兩直角，縮短工作流體沿管體軸向上的回流路徑，同時設定每一網格的第一夾角小於90度，工作流體沿垂直該兩第一夾角頂點連線的方向以較小的角度持續性地過渡，因此，有利於減小工作流體沿垂直該兩第一夾角頂點連線的方向上的回流阻力，大大提升工作流體沿軸向上的熱傳導效率，從而提升熱管性能。 Compared with the prior art, the heat pipe has at least one layer of capillary structure meshed into a diamond shape, and when the working fluid in the pipe body flows along the edge of the mesh, the path is replaced by the oblique edge to replace the two right angles of the traditional square mesh, and the working fluid is shortened. a return path in the axial direction of the tube body, and at the same time setting a first angle of each mesh to be less than 90 degrees, and the working fluid continuously transitions at a small angle along a direction perpendicular to the line connecting the vertices of the two first angles, thereby facilitating Reducing the backflow resistance of the working fluid in a direction perpendicular to the line connecting the apexes of the two first angles greatly improves the heat transfer efficiency of the working fluid in the axial direction, thereby improving the performance of the heat pipe.

請參閱圖1至圖3，該熱管100包括一扁平管體10，設於該管體10內的毛細結構20及注入該管體10的適量工作流體30(見圖7)。該熱管100沿軸向包括一蒸發段11及一冷凝段12。在本實施例中，該熱管100為薄型熱管。 Referring to FIGS. 1 to 3, the heat pipe 100 includes a flat tube body 10, a capillary structure 20 disposed in the tube body 10, and an appropriate amount of working fluid 30 (see FIG. 7) injected into the tube body 10. The heat pipe 100 includes an evaporation section 11 and a condensation section 12 in the axial direction. In the present embodiment, the heat pipe 100 is a thin heat pipe.

該管體10由銅等具有良好導熱性的材料製成。該管體10呈中空縱長扁平狀，其由一圓管壓扁而成。該管體10管壁的厚度小於1.5mm。該管體10包括一頂板13、一底板14及兩側板15。該頂板13與底板14相互平行且上下對稱，該兩側板15呈弧形，分別位於管體10的兩側並將頂板13和底板14連接。 The tube body 10 is made of a material having good thermal conductivity such as copper. The tube body 10 has a hollow longitudinally flat shape and is formed by flattening a round tube. The tube 10 has a wall thickness of less than 1.5 mm. The tube body 10 includes a top plate 13, a bottom plate 14, and two side plates 15. The top plate 13 and the bottom plate 14 are parallel to each other and vertically symmetrical. The two side plates 15 are curved, and are respectively located at two sides of the pipe body 10 and connect the top plate 13 and the bottom plate 14.

所述毛細結構20貼設於該管體10的整個內壁，並沿管體10的軸向從蒸發段11延伸至冷凝段12。該毛細結構20由銅、不銹鋼或纖維等材料編織成網狀結構。優選的，本發明中該毛細結構20由直徑為0.03mm至0.05mm的細金屬絲交錯編織而成。該毛細結構20上形成複數細小的孔隙(圖未示)，這些孔隙可產生毛細力，從而為工作流體30的回流提供動力。 The capillary structure 20 is attached to the entire inner wall of the pipe body 10 and extends from the evaporation section 11 to the condensation section 12 in the axial direction of the pipe body 10. The capillary structure 20 is woven into a mesh structure from a material such as copper, stainless steel or fiber. Preferably, in the present invention, the capillary structure 20 is interwoven by a thin metal wire having a diameter of 0.03 mm to 0.05 mm. A plurality of fine pores (not shown) are formed in the capillary structure 20, and the pores generate capillary forces to power the backflow of the working fluid 30.

請同時參閱圖4，所述毛細結構20包括複數呈菱形的網格21，每一網格21包括四條等長邊線213，所述網格21沿管體10軸向緊密排列。具體的，每一菱形網格21的邊長範圍位於0.10mm至0.25mm之間，每一網格21包括相對的兩個第一夾角211和相對的兩個第二夾角212，所述相對的兩第一夾角211均小於90度，且該兩個第一夾角211的頂點之間連線與該管體10的軸線平行。對應的，即所述相對的兩第二夾角212均大於90度而小於180度，使得兩個第一夾角211的頂點間連線的長度大於該兩個第二夾角212的頂點間連線長度。本實施例中，所述兩第一夾角211的角度均小於45度，對應兩第二夾角212的角度大於135度，如此可保證工作流體30的回流路徑設置至最佳的範圍內，同時將工作流體30沿兩第二夾角212頂點連線的方向上的回流阻力降至最低範圍內。可以理解的，該網格21的邊線213與該管體10軸線的夾角小於30度即可， 如此可保證該網格21兩第一夾角211的連線方向與管體10的軸線方向大致相同。 Referring to FIG. 4 at the same time, the capillary structure 20 includes a plurality of diamond-shaped meshes 21, and each of the meshes 21 includes four equal-length side lines 213, and the meshes 21 are closely arranged along the axial direction of the pipe body 10. Specifically, each diamond mesh 21 has a side length ranging between 0.10 mm and 0.25 mm, and each mesh 21 includes two opposite first angles 211 and two opposite second angles 212, the opposite Both first angles 211 are less than 90 degrees, and the line connecting the vertices of the two first angles 211 is parallel to the axis of the tube 10. Correspondingly, the two opposite second angles 212 are greater than 90 degrees and less than 180 degrees, such that the length of the line connecting the vertices of the two first angles 211 is greater than the length of the line connecting the vertices of the two second angles 212. . In this embodiment, the angles of the two first angles 211 are less than 45 degrees, and the angles corresponding to the two second angles 212 are greater than 135 degrees, so that the return path of the working fluid 30 is ensured to be within an optimal range, and The backflow resistance of the working fluid 30 in the direction of the line connecting the apexes of the two second angles 212 is minimized. It can be understood that the angle 213 between the edge 213 of the grid 21 and the axis of the tube 10 is less than 30 degrees. In this way, the connection direction of the two first corners 211 of the grid 21 is substantially the same as the axial direction of the pipe body 10.

工作時，管體10的蒸發段11與熱源接觸，工作流體30從蒸發段11處吸熱蒸發，帶著熱量從管體10中心的蒸汽通道(圖未示)運動至冷凝段12，在冷凝段12放熱後液化為液體，將熱量釋放出去，完成對發熱元件(圖未示)的散熱。該毛細結構20提供毛細力使在管體10的冷凝段12液化成液態的工作流體30沿網格21的邊線回流至蒸發段11，實現工作流體30在管體10的迴圈運動，以完成對發熱元件的持續散熱。本發明中，所述工作流體30為水、蠟、酒精或甲醇等具有較低沸點的物質。 In operation, the evaporation section 11 of the pipe body 10 is in contact with the heat source, and the working fluid 30 absorbs heat from the evaporation section 11 to evaporate, and carries heat from the steam passage (not shown) at the center of the pipe body 10 to the condensation section 12, in the condensation section. After exothermic, 12 is liquefied into a liquid, and the heat is released to complete the heat dissipation of the heating element (not shown). The capillary structure 20 provides a capillary force to cause the working fluid 30 liquefied into a liquid state in the condensation section 12 of the pipe body 10 to flow back to the evaporation section 11 along the edge of the mesh 21, thereby realizing the loop movement of the working fluid 30 in the pipe body 10 to complete Continuous heat dissipation of the heating element. In the present invention, the working fluid 30 is a substance having a lower boiling point such as water, wax, alcohol or methanol.

請同時參閱圖5，由於所述管體10內該種菱形網格21的形狀構造，管體內的工作流體沿網格21的邊線213流動時，路徑由斜邊取代傳統方形網格(虛線所示)的兩直角，使得冷凝段12液化的工作流體30流經最短範圍的回流路徑；同時由於第一夾角211小於90度，工作流體30沿兩第二夾角212頂點連線的方向以較小的角度和較短的路徑持續性地過渡，從而克服沿兩第二夾角212頂點連線的方向上的回流阻力，使得管體10內的工作流體30快速迴圈，從而保證該熱管100的高效性能。 Referring to FIG. 5 at the same time, due to the shape of the diamond mesh 21 in the tube body 10, when the working fluid in the tube body flows along the edge 213 of the mesh 21, the path is replaced by a hypotenuse to replace the traditional square grid (dotted line At two right angles, the working fluid 30 liquefied by the condensing section 12 flows through the shortest range of return flow paths; and since the first angle 211 is less than 90 degrees, the working fluid 30 is smaller along the line connecting the vertices of the two second angles 212. The angle and the shorter path continuously transition to overcome the backflow resistance in the direction along the line connecting the apexes of the two second angles 212, so that the working fluid 30 in the pipe body 10 is quickly circulated, thereby ensuring the efficiency of the heat pipe 100. performance.

請參閱圖6和圖7，為本發明另一實施例的熱管200。與第一實施例中的熱管100不同的係：該熱管200具有兩層毛細結構，其採用具有傳統方形網格22的毛細結構201和具有菱形網格23的毛細結構202交錯層疊的方式，所述方形網格22與菱形網格23直接接觸並且相互支撐，每一方形網格22包括四條等長邊線223。優選的，本實施例中，部分所述方形網格22與管體10軸向垂直的邊線 223可設置在菱形網格23兩第二夾角212的連線處，即此時方形網格22的邊線223與兩第二夾角212的連線在管體10內壁上的正射投影重疊，此時後續工作流體30的流動線路如圖8所示，管體10內的工作流體沿方形網格22的邊線223流動，路徑由斜邊(菱形網格23的邊線213)取代傳統方形網格22的兩直角邊(方形網格22的一條邊線223與另一條邊線223的一半)，此時菱形網格23縮短工作流體30沿兩第二夾角212頂點連線的方向上的回流路徑；同時由於第二夾角212大於90度而小於180度，相較沿方形網格22的兩直角邊流動而需要經過兩次直角過渡，工作流體30從方形網格22的邊線223流經菱形網格23的邊線213只需一次過渡，此過渡的角度明顯小於傳統的兩次直角過渡的和(180度)。因此，有利於減小工作流體30沿兩第二夾角212頂點連線的方向上的回流阻力，即此時管體10內部工作流體30沿管體10軸向上的回流路徑及回流阻力均可控製合理範圍內。同時由於菱形網格23與方形網格22的錯位配合，使工作流體30沿管體10徑向上的也可最大化的均勻傳熱，即此時毛細結構20的利用率可達理想狀態，熱管200的傳熱效率及傳熱均勻可達協調平衡。 Please refer to FIG. 6 and FIG. 7, which are heat pipes 200 according to another embodiment of the present invention. Different from the heat pipe 100 in the first embodiment: the heat pipe 200 has a two-layer capillary structure in which a capillary structure 201 having a conventional square mesh 22 and a capillary structure 202 having a diamond mesh 23 are alternately stacked. The square grid 22 is in direct contact with the diamond grid 23 and supports each other, and each square grid 22 includes four equal length edges 223. Preferably, in this embodiment, a part of the square mesh 22 is perpendicular to the axial direction of the pipe body 10 223 may be disposed at a line connecting the two second corners 212 of the diamond mesh 23, that is, the line 223 of the square mesh 22 and the line connecting the two second angles 212 overlap the orthographic projection on the inner wall of the pipe body 10, At this time, the flow line of the subsequent working fluid 30 is as shown in FIG. 8. The working fluid in the pipe body 10 flows along the side line 223 of the square mesh 22, and the path is replaced by a hypotenuse (the edge 213 of the diamond mesh 23) to replace the conventional square mesh. Two right-angled sides of 22 (one edge 223 of the square grid 22 and one half of the other edge 223), at which time the diamond-shaped grid 23 shortens the return path of the working fluid 30 in the direction of the line connecting the vertices of the two second angles 212; Since the second angle 212 is greater than 90 degrees and less than 180 degrees, two right angle transitions are required to flow along the two right angle sides of the square grid 22, and the working fluid 30 flows from the edge line 223 of the square grid 22 through the diamond grid 23 The edge 213 only needs one transition, and the angle of this transition is significantly smaller than the sum of the conventional two right angle transitions (180 degrees). Therefore, it is advantageous to reduce the backflow resistance of the working fluid 30 in the direction along the apex of the two second angles 212, that is, the return flow path and the backflow resistance of the working fluid 30 in the axial direction of the pipe body 10 at this time can be controlled. Within a reasonable range. At the same time, due to the misalignment of the diamond mesh 23 and the square mesh 22, the working fluid 30 can be uniformly heat-transferred along the radial direction of the pipe body 10, that is, the utilization rate of the capillary structure 20 can reach an ideal state, the heat pipe The heat transfer efficiency and heat transfer of 200 are evenly balanced.

與現有技術相比，上述熱管100至少將一層毛細結構20的網格21設置為菱形，且設定每一網格21的第一夾角211小於90度，使得管體10內的工作流體30沿網格21的邊線213流動時，路徑由斜邊取代傳統方形網格的兩直角邊，此時菱形的網格21縮短工作流體30沿管體10軸向上的回流路徑，相較常規具有編織而成的毛細結構20的熱管100，網格21內的工作流體30回流路徑縮短約19%；同時由於第一夾角小於90度，工作流體30流徑邊線213沿管體10徑向以較小的角度持續性地過渡，因此，有利於減小工作流體30沿 兩第二夾角212頂點連線的方向上的回流阻力。由於管體10軸向上的工作流體30具有較高的回流速度且流量得以保證，相較傳統的僅用方形網格22本發明至少一層菱形網格23沿軸向上的熱傳導效率大大提升，從而提升熱管100的散熱性能。 Compared with the prior art, the heat pipe 100 has at least one mesh 21 of the capillary structure 20 arranged in a diamond shape, and the first angle 211 of each mesh 21 is set to be less than 90 degrees, so that the working fluid 30 in the pipe body 10 is along the net. When the edge 213 of the cell 21 flows, the path replaces the two right-angled sides of the conventional square mesh by the oblique side. At this time, the diamond-shaped mesh 21 shortens the return path of the working fluid 30 along the axial direction of the pipe body 10, and is woven compared with the conventional one. The heat pipe 100 of the capillary structure 20, the return flow path of the working fluid 30 in the mesh 21 is shortened by about 19%; and since the first angle is less than 90 degrees, the flow path edge 213 of the working fluid 30 is at a small angle along the radial direction of the pipe body 10. Continuous transition, therefore, helps to reduce the working fluid 30 along The backflow resistance in the direction in which the apex of the two second angles 212 are connected. Since the working fluid 30 in the axial direction of the pipe body 10 has a high reflow speed and the flow rate is ensured, the heat transfer efficiency in the axial direction of the at least one diamond mesh 23 of the present invention is greatly improved compared with the conventional square mesh 22 alone, thereby improving The heat dissipation performance of the heat pipe 100.
