201116793 六、發明說明： 【發明所屬之技術領域】 本揭露係關於一種熱管，特別係關於一種震盪式熱管 〇 【先前技術】 熱管具有良好之熱傳性能，因此被廣泛地運用在電子 元件之散熱，特別是在個人電腦以及筆記型電腦之中幾乎 都可以看見熱管的運用。通常，面臨平©發熱形式之散熱 *求時，叹汁上必須同時採用多支熱管，方能滿足散熱之 需求。可是，多支熱管的使用會造成散熱設計、散熱模組 組裝與製作上的困難。因此，面對平面發熱形式之散熱要 求時，平板型熱管會是較傳統熱管為合適的傳熱元件。 運用具有毛細結構之平板型熱管，其困難在於毛細結 構之燒結製作，主要原因如下：i、平板型熱管越大型，毛 、-、·〇構之均勻度越難以控制，因而容易導致性能不穩定；2 φ 平板型熱官越大型，用於燒結毛細結構之燒結爐也必須 加大，從而導致成本增加，量產速度降低；3、退火後之平 板型熱管，其管壁強度大幅降低，因而可能導致其管壁不 具可因應内外部壓力變化所需之強度。既然因為毛細結構 的燒結’會衍生出許多製作上之問題，因此不具毛細結構 之震盪式熱官（pulsating heat pipe 〇r 〇sciUating 匕如 pipe) 便成為平面散熱之另一種選擇。 震盪式熱管之整體結構相當簡單，其係由一平滑的細 管連結而成。震盪式熱管之驅動力是藉由較小的管徑所產 201116793 生的毛細力、工作液體所受之重力以及受熱產生的汽泡壓 力來使熱管產生動作。然而傳統震a式熱管，其毛細力是 相當有限的，因此傳統震盈式熱管的運作主要還是利用重 力:由於傳統震i式熱管的運作主要靠的是重力，因此當 熱&處於水平或疋文熱端高於散熱端的狀況時，熱管將無 法運作。此—使用上之限制構成震i式熱管運用在平面散 熱要求之一主要的挑戰。201116793 VI. Description of the Invention: [Technical Field] The present disclosure relates to a heat pipe, particularly to an oscillating heat pipe. [Prior Art] A heat pipe has good heat transfer performance and is therefore widely used for heat dissipation of electronic components. The use of heat pipes can be seen almost everywhere, especially in personal computers and notebook computers. Usually, it faces the heat dissipation of the flat form. In the case of tempo, it is necessary to use multiple heat pipes at the same time to meet the heat dissipation requirements. However, the use of multiple heat pipes can cause difficulties in heat dissipation design and assembly and fabrication of heat dissipation modules. Therefore, in the face of the heat dissipation requirements of the planar heat generation, the flat type heat pipe is a suitable heat transfer element than the conventional heat pipe. The difficulty of using a flat-plate heat pipe with a capillary structure is the sintering of the capillary structure. The main reasons are as follows: i. The larger the flat-type heat pipe, the more difficult it is to control the uniformity of the hair, -, and the structure, which may easily lead to unstable performance. 2 φ flat type hot official is larger, the sintering furnace used for sintering the capillary structure must also be increased, resulting in increased cost and reduced mass production speed; 3. the flat-plate heat pipe after annealing has a greatly reduced wall strength. It may cause the wall of the pipe to have no strength required to respond to changes in internal and external pressure. Since the sintering of the capillary structure can cause many manufacturing problems, the pulsating heat pipe (〇r 〇sciUating such as pipe) without capillary structure becomes an alternative to planar heat dissipation. The overall structure of the oscillating heat pipe is quite simple, and it is made up of a smooth thin tube. The driving force of the oscillating heat pipe is to make the heat pipe act by the capillary force of the 201116793, the gravity of the working liquid, and the bubble pressure generated by the heat. However, the traditional a-type heat pipe has a very limited capillary force. Therefore, the operation of the traditional shock-type heat pipe mainly uses gravity: since the operation of the traditional shock-type heat pipe mainly relies on gravity, when the heat & is at the level or When the hot end of the text is higher than the heat sink, the heat pipe will not work. This – the use of the limitations constitutes one of the main challenges in the use of seismic heat pipes in the application of planar heat dissipation.

The flow channel system 12 can include a plurality of segments of the first flow channel 121 and a plurality of segments 201116793
二流道122，其中該些第一流道121與該些第二流道i22可沿 流道系統12交錯設置。各該第一流道121與各該第二流道 122可分別為一均勻流道，第一流道121之橫截面與第二流 道122兩者之橫截面不同。換言之，第一流道121之橫截面 與第二流道122之橫截面可分別具有不同的截面積，本揭露 不以此為限；第一流道121之橫截面與第二流道122之橫戴 面可分別具有不同之形狀，本揭露不以此為限；或者，第 一流道121之橫截面與第二流道122之橫截面可分別具有不 同之水力直徑（Hydraulic Diameter)，本揭露不以此為限。 第>;il道121與第^一流道122橫截面之不同可使位於其内之 工作流體具有不同之毛細力。流道系統12内之工作流體由 基板11上之注入口 133注入，當工作流體注入完畢後，再將 注入口 133封住。工作流體注入前，需從注入口 133將流道 系統12抽真空。 就本實施例言，第一流道121與第二流道122在垂直於 表面111之方向上可具相同的管深，而在第一流道121在橫 向上可具有較窄的管寬；而第二流道122在橫向上可具有較 寬的管寬，但本揭露不以此為限。又，該些第一流道121 與該些第二流道122可平行設置，且相鄰之第一流道121與 第二流道122之兩端處，分別以一彎流道123連接，但本揭 露不以此為限。位於流道系統12相對兩侧（圖2中上下兩側） 上端之第一流道121左端處1211與下端第二流道122之左端 處1221間，可利用一連接流道124連接，藉此形成一循環迴 路流道，其中該第一流道左端處1211可為入口處’而該第 201116793 二流道左端處1221之可為出口處。 由於第一流道121之管寬較第二流道122之管寬微小， 使得工作流體在第一流道121内之毛細力較在第二流道122 内為夫，因此當工作流體之兩端分別位於第一流道121與第 二流道122時，工作流體將被拉向第一流道121。當加熱區 134受熱時，工作流體會蒸發而增加蒸汽壓力，進而推動工 作流體之流動。高溫高壓之工作流體將會流至冷卻區132 ，亦即將熱由高溫之加熱區134送至低溫之冷卻區132，以 達到熱量傳遞之效果。該加熱區134係在連接流道124之另 一端，而冷卻區132與連接流道124同一端。另，當工作流 體受到蒸發流體之壓力擠壓時，由於工作流體流往第二流 道122之流阻較小，因此工作流體可較易被推向第二流道 122流動。本揭露藉流道系統12内因具有非均勻的流道結構 ，而使在流道系統12内之工作流體可受到不對稱之力量， 藉此促進震盪式熱管1之初始啟動運作，從而使震盪式熱管 1可水平放置操作。 圖3例示本揭露另一實施例之流道系統22之示意圖。流 道系統22包含複數段第一流道221及複數段第二流道222， 其中該些第一流道221與該些第二流道222係沿該流道系統 22交錯設置。第二流道222可為一均勻流道，而第一流道221 可包含一喷嘴結構223，藉此使第一流道221與第二流道222 可分別具有不同的橫截面，以讓工作流體於流道系統22内 因毛細力或流阻之差異在受熱啟動時容易流動。在本實施 例中，第一流道221與第二流道222可平行交錯設置，本揭 201116793 露不以此為限。 圖4例示本揭露又一實施例之流道系統32之示意圖。流 道系統32形成於一基板11上，其包含複數段第一流道321及 複數段第二流道322，第一流道321分別設置於第二流道322 之間。第二流道3 22可為一均勻流道，而第一流道321可包 含一孔口結構323，亦即第一流道321之截面積較第二流道 322之截面積小，藉此使第一流道321與第二流道322可分別 具有不同的橫截面，以讓工作流體於流道系統32内因毛細 力或流阻之差異在受熱啟動時容易流動。 圖5例示本揭露再一實施例之流道系統42之示意圖。除 依前述在基板11上加工形成之流道系統（丨2至32)之形式外 ，主要流道系統42為一密封彎折之金屬管所形成。流道系 統42包含複數段壓扁之管段423，而該些壓扁之管段423可 間隔形成，藉此在各壓扁之管段423上形成一第一流道421 ’而於各未壓扁或壓扁程度不同於第一流道421之管段形成 一第二流道422等截面不同之流道。金屬管亦可設置於基板 11之表面111上，以增加傳熱面積，金屬管與基板丨丨之表面 111可利用導熱膏或銲錫等形成熱耗接，本揭露不以此為限 實驗範例 在本實驗範例中’分別以圖2實施例之結構製作一傳統 震盪式熱官與一本揭露之震盈式熱管。在本揭露之震盈式 熱管之基板11上，第一流道121與第二流道122分別平行且 交錯形成，其中第一流道121之寬度為1毫米而第二流道122 201116793 之寬度為2亳米；而在傳統震盪式熱管之基板上，僅形成寬 度為2毫米之均勻流道。接著’以蓋板13分別密封本揭露之 震盪式熱管與傳統震盪式熱管並抽真空，然後再個別填充 約佔總流道系統體積百分之60之工作流體。接著，再對本 揭露之震盪式熱管與傳統震盪式熱管分別施以不同之熱量 (Qin)，並調整本揭露之震盪式熱管與傳統震盪式熱管之角 度，以量測本揭露之震盪式熱管與傳統震盪式熱管之受熱 端（τΗ)與散熱端（Tl)之溫度，最後藉由熱阻（Rth)計算公式： R>h -T^/Q^ 計算在各操作角度下，本揭露之震盪式熱管與傳統震 盪式熱管之熱阻與加熱量間之曲線，藉以比較兩者之性能 圖6 A與6 B分別例示傳統震盪式熱管與本揭露一實灰 例之震盪式熱管之熱阻曲線圖，橫座標為加熱瓦數（w)，絲 座標為熱阻rc/w)。從圖6A可發現，傳統震盈式熱管在7j 平放置，即操作角度為〇度時，不論加熱量大小，其熱阻袭 無變化且均在irc/w以上。由此顯示，傳統震盪式熱管名 水平放置時，無法發揮其散熱功能。相較地，本揭露之筹 盈式熱管在水平放置時，其熱阻低於15，且隨加敎量之妒 加，熱阻亦隨著降低。因此，由圖6B顯示可得知，本接屬 之震蓋式熱管即便以水平放置，仍能發揮其應有之散^ 能* 〇 *、、 於具有非均勻的流 不對稱之毛細力及 綜上所述，本揭露之震盪式熱管由 道結構’因而可讓其内之工作流體受到 201116793 進 流阻。當《式熱管受熱時’ X作流體同時受加熱蒸汽的 推動及不對稱之毛細力與流阻之影響，而往一方向上流動 。因此，本揭露之震盪式熱管之非均勻的流道結構可促 流道系統内之工作流體之初始啟動運作，而使其可水平放 置操作。The second flow path 122, wherein the first flow paths 121 and the second flow paths i22 are staggered along the flow channel system 12. Each of the first flow path 121 and each of the second flow paths 122 may be a uniform flow path, and the cross section of the first flow path 121 and the second flow path 122 are different in cross section. In other words, the cross section of the first flow path 121 and the cross section of the second flow path 122 may have different cross-sectional areas, respectively, and the disclosure is not limited thereto; the cross section of the first flow path 121 and the second flow path 122 are transversely worn. The surface may have different shapes, and the disclosure is not limited thereto; or the cross section of the first flow path 121 and the cross section of the second flow path 122 may have different hydraulic diameters respectively, and the disclosure does not This is limited. The difference between the >;il track 121 and the first pass 122 may cause the working fluid located therein to have a different capillary force. The working fluid in the flow path system 12 is injected from the injection port 133 on the substrate 11, and after the injection of the working fluid is completed, the injection port 133 is sealed. The runner system 12 is evacuated from the inlet 133 prior to injection of the working fluid. For the present embodiment, the first flow path 121 and the second flow path 122 may have the same tube depth in a direction perpendicular to the surface 111, and may have a narrow tube width in the lateral direction at the first flow path 121; The second flow path 122 may have a wider tube width in the lateral direction, but the disclosure is not limited thereto. Moreover, the first flow path 121 and the second flow paths 122 may be disposed in parallel, and the ends of the adjacent first flow path 121 and the second flow path 122 are respectively connected by a curved flow path 123, but Exposure is not limited to this. The left end 1211 of the first flow path 121 and the left end 1211 of the lower second flow path 122 located at opposite ends of the flow channel system 12 (upper and lower sides in FIG. 2) may be connected by a connecting flow path 124, thereby forming A circulating circuit flow path, wherein the first end of the first flow path 1211 can be an inlet portion and the left end of the 201116793 second flow path 1221 can be an outlet. Since the tube width of the first flow path 121 is smaller than the tube width of the second flow path 122, the capillary force of the working fluid in the first flow path 121 is higher than that in the second flow path 122, so that the two ends of the working fluid are respectively When located in the first flow path 121 and the second flow path 122, the working fluid will be pulled toward the first flow path 121. When the heated zone 134 is heated, the working fluid evaporates to increase the vapor pressure, which in turn promotes the flow of the working fluid. The high temperature and high pressure working fluid will flow to the cooling zone 132, that is, the heat is sent from the high temperature heating zone 134 to the low temperature cooling zone 132 to achieve the effect of heat transfer. The heating zone 134 is at the other end of the connecting flow path 124, and the cooling zone 132 is at the same end as the connecting flow path 124. Further, when the working fluid is pressed by the pressure of the evaporating fluid, since the flow resistance of the working fluid to the second flow path 122 is small, the working fluid can be more easily pushed toward the second flow path 122. It is disclosed that the working fluid in the flow channel system 12 can be subjected to an asymmetrical force due to the non-uniform flow channel structure in the borrowing channel system 12, thereby promoting the initial starting operation of the oscillating heat pipe 1, thereby making the oscillating type The heat pipe 1 can be placed horizontally. FIG. 3 illustrates a schematic diagram of a runner system 22 in accordance with another embodiment of the present disclosure. The flow channel system 22 includes a plurality of first flow channels 221 and a plurality of second flow channels 222, wherein the first flow channels 221 and the second flow channels 222 are staggered along the flow channel system 22. The second flow path 222 can be a uniform flow path, and the first flow path 221 can include a nozzle structure 223, whereby the first flow path 221 and the second flow path 222 can have different cross sections respectively to allow the working fluid to The flow path system 22 easily flows during warm start due to the difference in capillary force or flow resistance. In this embodiment, the first flow path 221 and the second flow path 222 may be arranged in parallel, which is not limited thereto. 4 illustrates a schematic diagram of a runner system 32 in accordance with yet another embodiment of the present disclosure. The flow channel system 32 is formed on a substrate 11 and includes a plurality of first flow channels 321 and a plurality of second flow channels 322. The first flow channels 321 are respectively disposed between the second flow channels 322. The second flow path 3 22 can be a uniform flow path, and the first flow path 321 can include an aperture structure 323, that is, the cross-sectional area of the first flow path 321 is smaller than the cross-sectional area of the second flow path 322, thereby The first runner 321 and the second runner 322 may each have a different cross section to allow the working fluid to flow easily in the runner system 32 due to differences in capillary forces or flow resistance during warm start. FIG. 5 illustrates a schematic diagram of a runner system 42 in accordance with yet another embodiment of the present disclosure. The main flow path system 42 is formed as a sealed and bent metal tube in addition to the flow path system (丨2 to 32) formed on the substrate 11 as described above. The flow channel system 42 includes a plurality of flattened tube sections 423, and the flattened tube sections 423 are spaced apart, thereby forming a first flow path 421 ' on each of the flattened tube sections 423 without being flattened or pressed The pipe section having a flatness different from that of the first flow passage 421 forms a flow passage having a different cross section such as a second flow passage 422. The metal tube may also be disposed on the surface 111 of the substrate 11 to increase the heat transfer area. The surface of the metal tube and the substrate 111 may be thermally coupled by using a thermal paste or solder. The disclosure is not limited to the experimental example. In the experimental example, a conventional oscillating thermal officer and a disclosed shock-type heat pipe were fabricated by the structure of the embodiment of Fig. 2, respectively. In the substrate 11 of the shock heat pipe of the present disclosure, the first flow path 121 and the second flow path 122 are respectively formed in parallel and staggered, wherein the first flow path 121 has a width of 1 mm and the second flow path 122 201116793 has a width of 2 In the case of a conventional oscillating heat pipe, only a uniform flow path having a width of 2 mm is formed. Then, the oscillating heat pipe of the present disclosure and the conventional oscillating heat pipe are respectively sealed by the cover plate 13 and vacuumed, and then the working fluid is filled with about 60% of the volume of the total flow channel system. Then, the oscillating heat pipe of the present disclosure and the conventional oscillating heat pipe are respectively subjected to different heat (Qin), and the angle between the oscillating heat pipe and the conventional oscillating heat pipe of the present disclosure is adjusted to measure the oscillating heat pipe of the present disclosure. The temperature of the heat-receiving end (τΗ) and the heat-dissipating end (Tl) of the conventional oscillating heat pipe is finally calculated by the thermal resistance (Rth) formula: R>h -T^/Q^ Calculate the shock of the present disclosure under various operating angles The relationship between the heat resistance and the heating capacity of the conventional heat pipe and the heat pump is compared to compare the performance of the two. Figure 6A and 6B respectively illustrate the thermal resistance curves of the conventional oscillating heat pipe and the oscillating heat pipe of the present example. Figure, the horizontal coordinate is the heating wattage (w), and the wire coordinates are the thermal resistance rc/w). It can be seen from Fig. 6A that the conventional shock-type heat pipe is placed at 7j flat, that is, when the operating angle is twist, the thermal resistance does not change and is above the irc/w regardless of the amount of heating. This shows that the traditional oscillating heat pipe name cannot be used for its heat dissipation function when placed horizontally. In comparison, the thermal resistance of the disclosed heat pipe is less than 15 when placed horizontally, and the thermal resistance decreases as the amount of twisting increases. Therefore, as shown in FIG. 6B, it can be seen that the shock cap type heat pipe of the present invention can exert its proper function of dissipating energy**, and having capillary force with non-uniform flow asymmetry even when placed horizontally. In summary, the oscillating heat pipe of the present disclosure is constructed such that the working fluid therein is subjected to the 201116793 flow resistance. When the "heat pipe is heated", the X fluid is simultaneously driven by the heated steam and the asymmetrical capillary force and flow resistance, and flows upwards in one direction. Thus, the non-uniform flow path structure of the oscillating heat pipe of the present disclosure facilitates the initial startup operation of the working fluid within the flow path system, allowing it to be placed horizontally.
