Description
本發明係與熱管有關，特別是指一種一端較大的熱管及其製造方法。 The invention relates to a heat pipe, in particular to a heat pipe having a larger end and a manufacturing method thereof.
習知之熱管，乃是在銅管中設置一層毛細組織並注入作動液，藉由作動液的汽相及液相間的轉換以及毛細組織的毛細現象來快速導引液體的效果，形成極為快速的熱循環系統，可使得整個熱管很快的形成溫度均勻的狀態，因而又稱為均溫管。 The conventional heat pipe is to set a layer of capillary structure in the copper pipe and inject the activating liquid, and to quickly guide the liquid by the conversion of the vapor phase and the liquid phase of the liquid and the capillary phenomenon of the capillary structure, forming an extremely fast The thermal cycle system allows the entire heat pipe to form a uniform temperature quickly, which is also called a temperature equalization pipe.
熱管目前所知，大多是單純的管體架構，一般常見於個人電腦的CPU(中央處理單元)或繪圖晶片上的散熱模組，而藉由熱管用來把晶片的熱能導引到散熱模組上。 Currently known as heat pipes, most of them are simple pipe structures. They are commonly used in CPUs (central processing units) of personal computers or heat dissipation modules on graphics chips, and heat pipes are used to guide the thermal energy of the chips to the heat dissipation module. on.
傳統的熱管在某些場合，例如空間受到限制時，需要以其一端來與熱源接觸來達到導熱散熱的功能，這樣的使用方式，會因為熱源與熱管接觸面積小而使得熱通量很小，導熱或散熱的效果即較差。中國專利第CN 203443442 U號專利案，即揭露了此種熱管。然而，傳統熱管均僅為單純的管體構造而已，並沒有在一端結合其他結構來增加與熱源的接觸面積，進而達到較佳的導熱及散熱效果者。 In some cases, such as when the space is limited, the heat pipe needs to be in contact with the heat source at one end to achieve the function of heat conduction and heat dissipation. The use mode is such that the heat source is small because the contact area between the heat source and the heat pipe is small. The effect of heat conduction or heat dissipation is poor. This heat pipe is disclosed in Chinese Patent No. CN 203443442 U. However, the conventional heat pipe is only a simple pipe structure, and does not combine other structures at one end to increase the contact area with the heat source, thereby achieving better heat conduction and heat dissipation effects.

The larger heat pipe 10 is mainly composed of a lower cover 11, an upper cover 13, a pipe body 15, a main capillary structure 17, and an actuating liquid (not shown), wherein: the lower cover 11 is in the first In the examples, it was in the form of a flat plate.
該上蓋13，結合於該下蓋11，而於內部形成一腔室C，該 上蓋13具有一結合孔131。於本第一實施例中，該上蓋13周圍係沿垂直於該上蓋13的方向延伸一周壁132而呈筒狀，且該上蓋13係於該結合孔131之周緣沿著該結合孔131之軸向向外延伸一固定壁133；該固定壁在實施上亦可以沿該結合孔之軸向向內延伸，並不以向外為限，而由於此種實施方式乃是可由本實施例所理解，因此不再以圖式表示。 The upper cover 13 is coupled to the lower cover 11 to form a chamber C therein. The upper cover 13 has a coupling hole 131. In the first embodiment, the upper cover 13 has a cylindrical shape extending in a direction perpendicular to the upper cover 13 and has a cylindrical shape, and the upper cover 13 is attached to the periphery of the coupling hole 131 along the axis of the coupling hole 131. Extending outwardly from a fixed wall 133; the fixed wall may also extend inwardly along the axial direction of the coupling hole, and is not limited to the outside, and since such an embodiment is understood by the embodiment, Therefore, it is no longer represented by a schema.
該管體15，內壁具有一管內毛細組織層151，該管體15之一端係穿入該結合孔131而與該上蓋13結合，另一端係封閉。於本第一實施例中，該管體15對應於該結合孔131的該端末段，係形成口徑較該管體15大之一大徑部152，並以該大徑部152穿入該結合孔131而與該上蓋13結合。於本第一實施例中，該管體15係以其一端之外壁結合於該上蓋13之固定壁133上，該固定壁133可提供較佳之固定管體15的效果，然而，不設置該固定壁133時，該管體15亦可直接的結合於該上蓋13，並不以該固定壁133之設置為限。 The inner wall of the tubular body 15 has an inner capillary structure layer 151. One end of the tubular body 15 penetrates the coupling hole 131 to be coupled with the upper cover 13, and the other end is closed. In the first embodiment, the tubular body 15 corresponds to the end portion of the coupling hole 131, and a large diameter portion 152 having a larger diameter than the tubular body 15 is formed, and the coupling is penetrated by the large diameter portion 152. The hole 131 is combined with the upper cover 13. In the first embodiment, the tubular body 15 is coupled to the fixed wall 133 of the upper cover 13 by an outer wall of one end thereof. The fixed wall 133 can provide the effect of preferably fixing the tubular body 15, however, the fixing is not provided. When the wall 133 is used, the tube body 15 can also be directly coupled to the upper cover 13 and is not limited to the setting of the fixed wall 133.
該主毛細結構17，具有一底座毛細組織171以及一交接毛細組織172，該交接毛細組織係由該底座毛細組織171一起燒結成形而向外延伸預定長度的一交接毛細組織172，該底座毛細組織171係位於該腔室C內，該交接毛細組織172係由該腔室C向外穿出該結合孔131而伸入該管體15內之局部，且交接或接觸於該管體15內之管內毛細組織層151，其交接狀態如第4圖所示。該底座毛細組織171具有由周面向內延伸的複數第一通道P1，該交接毛細組織172具有貫穿其自身的之一第二通道P2，該些第一通道P1與該第二通道P2係交會於該底座毛細組織171內且在空間上相連通，並且該管體15內部的空間在空間上與該第二通道P2相連通。 The primary capillary structure 17 has a base capillary structure 171 and a transfer capillary structure 172. The transfer capillary structure is sintered together by the base capillary structure 171 to extend outwardly by a predetermined length of a transfer capillary structure 172. The base capillary structure The 171 is located in the chamber C, and the interface capillary structure 172 extends outwardly from the chamber C into the portion of the tube body 15 and is in contact with or in contact with the tube body 15. The capillary structure layer 151 in the tube is placed as shown in Fig. 4. The base capillary structure 171 has a plurality of first passages P1 extending inwardly from the circumferential surface, the intersection capillary structure 172 having a second passage P2 extending through itself, the first passages P1 and the second passages P2 intersecting The base capillary structure 171 is internally and spatially connected, and a space inside the tubular body 15 is spatially connected to the second passage P2.
該作動液(圖中未示)，係填入該管體15內。由於作動液係涵容於該主毛細結構17中而難以圖式表示，且作動液為熱管相關技術領域者所熟知之元件，因此在圖中不予表示。 The working fluid (not shown) is filled into the tubular body 15. Since the operating fluid is contained in the main capillary structure 17, it is difficult to graphically represent, and the operating fluid is an element well known to those skilled in the art of heat pipes, and therefore will not be shown in the drawings.
其中，該主毛細結構17之底座毛細組織171係燒結固定於該下蓋11、該上蓋13、及該下蓋11與該上蓋13的組合三者其中之一，於本第一實施例中係以燒結於該下蓋11為例。該管內毛細組織層151係選自複數溝槽、燒結金屬粉末(例如銅粉)、金屬絲束及織網其中之一，於本第一 實施例中係以複數溝槽為例。該管體15的大徑部152乃係為了使管體15與上蓋13之間的接合得以更緊密，然而，不設置該大徑部152亦可完成該交接毛細組織172與該管體15之組裝，並不以設置該大徑部152為限。 The base capillary structure 171 of the main capillary structure 17 is sintered and fixed to the lower cover 11, the upper cover 13, and a combination of the lower cover 11 and the upper cover 13, which is the first embodiment. The sintering is performed on the lower cover 11 as an example. The in-tube capillary structure layer 151 is selected from the group consisting of a plurality of grooves, a sintered metal powder (for example, copper powder), a metal wire bundle, and a woven mesh. In the embodiment, a plurality of trenches are taken as an example. The large diameter portion 152 of the tubular body 15 is for tighter engagement between the tubular body 15 and the upper cover 13, however, the overlapping of the capillary structure 172 and the tubular body 15 can be completed without providing the large diameter portion 152. The assembly is not limited to the provision of the large diameter portion 152.
須補充說明的是，於本第一實施例中，該底座毛細組織171係以圓盤狀為例說明，而該下蓋11及該上蓋13則亦以圓板狀或圓筒狀為例。然而，該底座毛細組織171並不以圓盤狀為限，其亦可製作為矩形，而該下蓋11及該上蓋13則須對應做為矩形板狀或矩形筒狀以配合實施。 It should be noted that in the first embodiment, the base capillary structure 171 is illustrated by a disk shape, and the lower cover 11 and the upper cover 13 are also in the form of a disk or a cylinder. However, the base capillary structure 171 is not limited to a disk shape, and may be formed in a rectangular shape, and the lower cover 11 and the upper cover 13 are required to be correspondingly formed into a rectangular plate shape or a rectangular tube shape.
以上說明了本第一實施例之架構，接下來說明本第一實施例之操作狀態。 The architecture of the first embodiment has been described above, and the operational state of the first embodiment will be described next.
如第6圖配合第3圖所示，在使用時，係將該下蓋11之底面置於一發熱源H(例如一電路板上之晶片)上，此時該管體15即處於以一端接觸該發熱源H的狀態。該發熱源H的熱能傳導至該下蓋11時，涵容於該主毛細結構17之底座毛細組織171中的該作動液即會蒸發為而呈汽相，呈汽相的作動液即經由該些第一通道P1擴散至該第二通道P2，進而上升至該管體15中，並於該管體15之管壁凝結成水，再藉由該管內毛細組織層151將之吸引至該交接毛細組織172，進而回流至該底座毛細組織171中。藉此，該作動液即可藉由液相及汽相之間的變化來傳導熱能，而達到均溫導熱的效果。此種架構由於是以口徑較大的該下蓋11做為受熱面，而以口徑較小的該管體15做為作動液汽相及液相之變化區域，因此不是整體的口徑都與該下蓋11一樣大。藉此，本發明之一端具有較大的接觸面積且身部與傳統熱管相似，較習知熱管而言在一端具有更大的接觸面積而可達到更佳的導熱或散熱效果。 As shown in FIG. 6 in conjunction with FIG. 3, in use, the bottom surface of the lower cover 11 is placed on a heat source H (for example, a wafer on a circuit board), and the tube body 15 is at one end. The state in which the heat source H is contacted. When the heat energy of the heat source H is transmitted to the lower cover 11, the operating fluid contained in the base capillary structure 171 of the main capillary structure 17 evaporates to form a vapor phase, and the actuating liquid in the vapor phase passes through the The first channel P1 diffuses to the second channel P2, and then rises into the tube body 15, and condenses into water on the tube wall of the tube body 15, and then attracts the tube to the junction by the capillary structure layer 151 in the tube. The capillary structure 172 is further returned to the base capillary structure 171. Thereby, the actuating liquid can conduct heat energy by changing between the liquid phase and the vapor phase, thereby achieving the effect of uniform temperature heat conduction. Because the lower cover 11 has a larger diameter, the lower cover 11 is used as a heating surface, and the tubular body 15 having a smaller diameter is used as a change region of the liquid phase and the liquid phase of the liquid, so that the overall diameter is not The lower cover 11 is as large. Thereby, one end of the invention has a large contact area and the body is similar to a conventional heat pipe, and has a larger contact area at one end than a conventional heat pipe to achieve better heat conduction or heat dissipation.
請再參閱第7圖，本發明第二實施例所提供之一種一端較大的熱管20，主要概同於前揭第一實施例，不同之處在於：該上蓋23係不設有周壁，而該下蓋21則於周圍沿垂直於該下蓋21的方向延伸一周壁212而呈筒狀。 Referring to FIG. 7 , a heat pipe 20 having a larger end is provided in the second embodiment of the present invention, which is mainly similar to the first embodiment disclosed above, except that the upper cover 23 is not provided with a peripheral wall.

可以理解的是，亦可以在第一次的燒結先成形出該主毛細結構47，再以第二次的燒結來將該主毛細結構47燒結固定於該上蓋上，並不以燒結於該下蓋為限制。此種燒結方式可由本第五實施例所推知，因此容不再以圖式表示之。 It can be understood that the main capillary structure 47 can be formed first in the first sintering, and the main capillary structure 47 can be sintered and fixed on the upper cover by the second sintering, and is not sintered. Cover is limited. Such a sintering method can be inferred from the fifth embodiment, and therefore the capacity is not represented by the drawings.
本第五實施例僅在步驟上與前揭第四實施例略有差異，其餘技術特徵及所能達成之功效均概同於前揭第四實施例，容不再予贅述。 The fifth embodiment is slightly different from the fourth embodiment in the previous step. The other technical features and the functions that can be achieved are the same as those in the fourth embodiment, and will not be further described.
請再參考第17圖至第18圖，本發明第六實施例所提供之一種一端較大的熱管之製造方法，主要概同於前揭第四實施例，不同之處在於：在該c)燒結步驟中，係僅燒結該主毛細結構57，並不與該下蓋51一起燒結。 Referring to FIG. 17 to FIG. 18 again, a method for manufacturing a heat pipe having a larger end portion according to a sixth embodiment of the present invention is mainly similar to the fourth embodiment disclosed above, except that: In the sintering step, only the main capillary structure 57 is sintered and is not sintered together with the lower cover 51.

The base capillary structure 571 of the main capillary structure 57 is located in the chamber C (refer to FIG. 3). The overlapping capillary structure 572 of the primary capillary structure 57 passes through the coupling hole 531.
在該e)組合步驟之前以及該e0)預先組合步驟之後還更包含有一e1)第二次燒結步驟：將該上蓋53、該下蓋51與該主毛細結構57一起燒結。 Before the e) combining step and after the e0) pre-combining step, there is further included an e1) second sintering step: sintering the upper cover 53 and the lower cover 51 together with the main capillary structure 57.
藉此，乃是以第一次的燒結先成形出該主毛細結構57，再預先把該主毛細結構57置於該上蓋53與該下蓋51之間並予蓋合，再以第二次的燒結來將該主毛細結構57燒結固定於該下蓋51與該上蓋53之間。 Thereby, the main capillary structure 57 is first formed by sintering for the first time, and the main capillary structure 57 is placed between the upper cover 53 and the lower cover 51 in advance and covered, and then the second time The sintering is performed to fix and fix the main capillary structure 57 between the lower cover 51 and the upper cover 53.
本第六實施例僅在步驟上與前揭第四實施例略有差異，其餘技術特徵及所能達成之功效均概同於前揭第四實施例，容不再予贅述。 The sixth embodiment is only slightly different from the foregoing fourth embodiment in the steps, and the remaining technical features and the functions that can be achieved are the same as those in the fourth embodiment, and will not be further described.
請再參考第19圖及第20圖，本發明第七實施例所提供之一種一端較大的熱管之製造方法，主要概同於前揭第四實施例，不同之處在於：該下蓋61周圍係沿垂直於該下蓋61的方向延伸一周壁612而呈筒狀，該上蓋63係不設有周壁。 Referring to FIG. 19 and FIG. 20 again, a manufacturing method of a heat pipe having a larger end is provided in the seventh embodiment of the present invention, which is mainly similar to the fourth embodiment disclosed above, except that the lower cover 61 is provided. The surrounding portion has a cylindrical shape extending in a direction perpendicular to the lower cover 61, and the upper cover 63 is not provided with a peripheral wall.
在該b)金屬粉末置入治具步驟中，係將該金屬粉末64及該上蓋63置入該治具69之容置槽691，並使該凸伸部642穿過該上蓋63的結合孔631且使該上蓋63貼接於該金屬粉末64之底座部641之一端面。 In the step of placing the metal powder into the jig, the metal powder 64 and the upper cover 63 are placed in the receiving groove 691 of the jig 69, and the protruding portion 642 is passed through the bonding hole of the upper cover 63. The upper cover 63 is attached to one end surface of the base portion 641 of the metal powder 64.

藉此，乃是將該主毛細結構67在燒結時直接的燒結固定於該上蓋63上。 Thereby, the main capillary structure 67 is directly sintered and fixed to the upper cover 63 at the time of sintering.
本第七實施例僅在步驟上與前揭第四實施例略有差異，其餘技術特徵及所能達成之功效均概同於前揭第四實施例，容不再予贅述。 The seventh embodiment is only slightly different from the foregoing fourth embodiment in the steps, and the remaining technical features and the functions that can be achieved are the same as those in the fourth embodiment, and will not be further described.
請再參考第21圖及第23圖，本發明第八實施例所提供之一種一端較大的熱管之製造方法，主要概同於前揭第四實施例，不同之處在於： 在該b)金屬粉末置入治具步驟中，如第21圖所示，該金屬粉末74受該容置槽791之形狀塑形而僅形成該底座部741，並沒有形成凸伸部；此外，該軸芯棒793係沿垂直該些側芯棒792的方向穿入該底座部741。再者，該治具79或該軸芯棒793係具有一環緣794***至該底座部741一預定深度，於本實施例中係以該治具79具有該環緣794為例。 Referring to FIG. 21 and FIG. 23, a method for manufacturing a heat pipe having a larger end is provided in the eighth embodiment of the present invention, which is mainly similar to the fourth embodiment disclosed above, except that: In the step of placing the metal powder into the jig, as shown in FIG. 21, the metal powder 74 is shaped by the accommodating groove 791 to form only the base portion 741, and no protrusion is formed; The shaft core rod 793 penetrates the base portion 741 in a direction perpendicular to the side core rods 792. Furthermore, the jig 79 or the shaft core 793 has a ring edge 794 inserted into the base portion 741 to a predetermined depth. In the present embodiment, the jig 79 has the ring edge 794 as an example.
在該c)燒結步驟中，該主毛細結構77僅對應該底座部741形成該底座毛細組織771，該底座毛細組織771對應於該環緣794***的位置係形成一環槽774(示於第22圖)，且該環槽774所圍合之毛細組織即定義為該交接毛細組織772。 In the c) sintering step, the main capillary structure 77 forms the base capillary structure 771 only corresponding to the base portion 741, and the base capillary structure 771 forms a ring groove 774 corresponding to the position where the ring edge 794 is inserted (shown at the 22nd FIG. 4), and the capillary structure enclosed by the annular groove 774 is defined as the delivery capillary structure 772.
在該e)組合步驟中，如第22圖及第23圖所示，該管體75係局部***該底座毛細組織771之環槽774，該交接毛細組織772在此組合狀態下係伸入該管體75而交接或接觸於該管內毛細組織751。 In the e) combining step, as shown in FIGS. 22 and 23, the tube body 75 is partially inserted into the ring groove 774 of the base capillary structure 771, and the transfer capillary structure 772 is inserted into the combined state. The tube body 75 is in contact with or in contact with the capillary structure 751 in the tube.
於本第八實施例中，主要是該交接毛細組織772的形成方式不同於前揭第四實施例，至於其餘之技術特徵及所能達成之功效均概同於前揭第四實施例，容不再予贅述。 In the eighth embodiment, the manner in which the transfer capillary structure 772 is formed is different from that in the fourth embodiment. The remaining technical features and the achievable effects are the same as those in the fourth embodiment. I will not repeat them.
