M375861 五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係與一種熱傳元件有關，尤指一種扁平狀熱管内 部的毛細結構。 【先前技術】 [0002] 按，熱管（Heat pipe )係為一種利用液、汽相變化來 達到快速傳遞熱量的熱傳元件，且為了產生溫差，通常 係以熱管的一端作為蒸發部、另一端作為冷凝部；當蒸 發部遇熱時，其内部之工作流體因熱管内部為真空而能 快速汽化，再透過熱管内朝向較低溫的冷凝部傳遞，此 時冷凝部再透過外界的散熱元件（如鰭片）釋放熱量， 使汽化的工作流體以恢復成液相，再透過熱管内壁上的 毛細組織回傳至蒸發部，如此循環即可重覆進行熱傳作 用0 [0003] 而以往為了使熱管不佔空間而更易於設置在薄型化的電 子產品中，亦有將熱管扁平化來達到上述需求。然而， 當熱管被壓製呈扁平狀後，其管内部的空間將大幅減少 ，僅存留供毛細結構或支撐體容置的些許空間。因此， 當工作流體於蒸發部遇熱轉變為汽相時，也會因為熱管 内部的空間減少，而造成汽化的工作流體不易朝向冷凝 部作傳遞等問題。 [0004] 有鑑於此，本創作人係為改善並解決上述之缺失，乃特 潛心研究並配合學理之運用，終於提出一種設計合理且 有效改善上述缺失之本創作。 表單编號A0101 第3頁/共20頁 【新型内容】 [0005] 本創作之主要目的，在於可提供一種扁平狀熱管結構， 其係透過熱管内部之毛細組織的結構設計，使熱管在蒸 發部與傳遞段内部的毛細組織，在橫裁斷面上不等同； 詳言之，係使毛細組織在蒸發部的橫截斷面大於傳遞段 的橫戴斷面，如此，熱管在傳遞段即可預留空間而形成 氣體流道，以供汽化的工作流體可通過所述氣體流道而 朝向冷凝部傳遞。 [0006] 為了達成上述之目的，本創作係提供一種扁平狀熱管結 構，包括一扁平狀管體、以及設於管體内壁的毛細組織 ，管體内封存有工作流體，而毛細組織則包含第一毛細 部、以及連接於第一毛細部之傳輸毛細部；其中，第一 毛細部在橫截斷面上係大於傳輸毛細部，以於管體内形 成有與傳輸毛細部並列的氣體流道。 [0007] 為了達成上述之目的，本創作係提供一種扁平狀熱管結 構，包括一扁平狀管體、以友設於管體内壁的毛細組織 ，管體具有作為熱管的蒸發部與冷凝部，其内封存有工 作流體，而毛細組織則包含第一毛細部、以及連接於第 一毛細部之傳輸毛細部，且第一毛細部位於作為熱管的 蒸發部内，而傳輸毛細部則朝向作為熱管的冷凝部延伸 ;其中，第一毛細部在橫截斷面上係大於傳輸毛細部， 以於管體内形成有與傳輸毛細部並列的氣體流道。 【實施方式】 [0008] 為了使貴審查委員能更進一步瞭解本創作之特徵及技 術内容，請參閱以下有關本創作之詳細說明與附圖，然 表單編號A0101 第4頁/共20頁 M375861 而所附圖式僅提供參考與朗用，並麵㈣本創作加 以限制者。 闺料_ — ®摘作第-實施例之 立體分解衫岐立體組合示㈣。本創作係提供一種 扁平狀熱管結構，該熱们包括一扁平狀管體1〇 '以及設 於該管體ίο内壁之毛細組織u ;其中： [0010] 該管體1〇内亦具有-呈扁平狀的容置空間1〇〇，上述毛細 組織11至少貼附於該容置空間100之一側内壁上（即如第 三圖所示）、亦或可同時貼附於其二側内壁間（圖略） 。管體10内封存有適量之工作流體（圖略）。 [0011] 該毛細組織11包含第一毛細部110、第二毛細部U1、以 及連接於第-、二毛細部11〇、112間之傳輸毛細部ιΐ2 ，其中，所述第一毛細部Π0係位於熱管1作為蒸發部内 ，第二毛細部111則位於熱管丨作為冷凝部内，而傳輸毛 細部112在橫截斷面上皆小於所述第一、二毛細部ιι〇 、111的橫截斷面（本創作所舉之各實施例，係以橫截斷 面的寬度而言）。如此，即可於熱管〗作為傳遞段内形成 有與傳輸毛細部112並列的氣體流道12，以供汽化的工 作流體可通過所述氣體流道12而朝向熱管1的冷凝部傳遞 。而在本實施例中，該傳輸毛細部112係置於管體1〇内的 中間處，故於該傳輸毛細部Π2二側分別形成有一所述氣 體流道12。 [0012] 是以，藉由上述之構造組成，即可得到本創作扁平狀熱 管結構。 表單編號A0101 第5頁/共20頁 圆據此，如第四_示，將熱管1蒸發部接觸於-熱源2上 ，而熱官1冷凝部上則串接有複數散熱鰭片3 ;當熱源2產 生熱量時，位於熱管】内第一毛細部11〇的工作流體開始 汽化，而由於第一毛細部110的橫戴斷面大於傳輸毛細部 112的橫截斷面，故汽化的工作流體可由第_毛細部 邊界通往氣體流道12，以透過氣體流道12傳遞至熱管 凝部，而不會與回流的液態工作流體發生對向流動阻擾 ，進而使熱管1内的液、汽相變化循環更為順暢。 [OOM]此外，如第五圖所示，係為本創作第二實施例之立體組 合不意圖；其中，熱管1作為冷凝部内的毛細組織n亦可 與傳輸毛細部112具有相同的橫截斷面或其寬度，而不需 使第一毛細部1 1 1之橫截斷面亦大於傳輸毛細部1 1 2的橫 截斷面，僅需使傳輸毛細部H2連接第一毛細部110後， 朝向熱管1冷凝部延伸，蓋因工作流體由熱管丨冷凝部回 復成液態時，可直接透過傳輸毛細部1 1 2快速回流至第一 毛細部110，無須存積於熱管丨备凝娘内。 ..,· [〇〇15]再者，如第六圖所示，係為本創作第三實施例之立體組 合不意圖；其中，該傳輸毛細部112係位於偏向管體1〇内 的一側處，故僅於管體1〇内的另一側形成有一所述氣體 流道12。又，如第七圖所示，係為本創作第四實施例之 立體組合示意圖；其中，根據上述第三實施例亦可使熱 管1作為冷凝部内的毛細組織11，與該傳輸毛細部112具 有相同的橫截斷面或其寬度。 [0016]再者，如第八圖及第九圖所示，係為本創作第五實施例 之立體組合示意圖及使用狀態示意圖：其中，熱管1亦 第6頁/共20頁 表單編號A0101 M375861 可提供複數蒸發部，以分別對應一熱源2，而各蒸發部内 的毛細組織11皆為所述第一毛細部11 0，且各第一毛細部 110間由一所述傳輸毛細部112連接。如此，亦可供該熱 管1應用於多熱源2的場合上。值得一提的是：位於任二 所述傳輸毛細部112間的第一毛細部110，其在橫截斷面 上可小於位在管體10内最二側的第一毛細部110，但仍大 於傳輸毛細部112,俾供汽化的工作流體於管體10内仍 有空間傳輸。 [0017] 綜上所述，本創作實為不可多得之新型創作產品，其確 可達到預期之使用目的，而解決習知之缺失，又因極具 新穎性及進步性，完全符合新型專利申請要件，爰依專 利法提出申請，敬請詳查並賜准本案專利，以保障創作 人之權利。M375861 V. New description: [New technical field] [0001] This creation is related to a heat transfer element, especially the capillary structure inside a flat heat pipe. [Prior Art] [0002] Heat pipe is a heat transfer element that uses liquid and vapor phase changes to achieve rapid heat transfer. In order to generate a temperature difference, one end of the heat pipe is usually used as the evaporation part and the other end. As the condensation part; when the evaporation part is hot, the internal working fluid can be quickly vaporized by the vacuum inside the heat pipe, and then transmitted through the heat pipe to the lower temperature condensation part, and the condensation part passes through the external heat dissipation component (such as The fins release heat, and the vaporized working fluid is returned to the liquid phase, and then passed through the capillary structure on the inner wall of the heat pipe to the evaporation portion, so that the heat transfer can be repeated in the cycle. [0003] In the past, in order to make the heat pipe It is easier to install in thin electronic products without taking up space, and flattening heat pipes to meet the above requirements. However, when the heat pipe is pressed into a flat shape, the space inside the pipe is greatly reduced, leaving only a small space for the capillary structure or the support body to accommodate. Therefore, when the working fluid is converted into a vapor phase by heat in the evaporation portion, the space inside the heat pipe is also reduced, so that the vaporized working fluid is less likely to be transmitted toward the condensation portion. [0004] In view of this, the creator has improved and solved the above-mentioned shortcomings, and has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The capillary structure inside the transfer section is not equal in the cross section; in detail, the cross section of the capillary structure in the evaporation section is larger than the cross section of the transfer section, so that the heat pipe can be reserved in the transfer section The gas flow path is formed by the space, and the working fluid for vaporization can be transferred to the condensation portion through the gas flow path. [0006] In order to achieve the above object, the present invention provides a flat heat pipe structure including a flat pipe body and a capillary structure disposed on the inner wall of the pipe body, the working fluid is sealed in the pipe body, and the capillary structure includes the first a capillary portion and a transfer capillary portion connected to the first capillary portion; wherein the first capillary portion is larger in cross section than the transfer capillary portion to form a gas flow passage juxtaposed with the transfer capillary portion in the tubular body. [0007] In order to achieve the above object, the present invention provides a flat heat pipe structure, comprising a flat tube body, a capillary structure disposed on the inner wall of the tube body, the tube body having an evaporation portion and a condensation portion as a heat pipe, The inner seal contains a working fluid, and the capillary structure includes a first capillary portion and a transfer capillary portion connected to the first capillary portion, and the first capillary portion is located in the evaporation portion as the heat pipe, and the transfer capillary portion is oriented toward the condensation as the heat pipe. The portion extends; wherein the first capillary portion is larger than the transfer capillary portion in a cross-sectional area, so that a gas flow path juxtaposed with the transfer capillary portion is formed in the tube body.

(figure omitted). A proper amount of working fluid is sealed in the pipe body 10 (not shown). [0011] The capillary structure 11 includes a first capillary portion 110, a second capillary portion U1, and a transfer capillary portion ι2 connected between the first and second capillary portions 11〇, 112, wherein the first capillary portion Π0 is The heat pipe 1 is located in the evaporation portion, the second capillary portion 111 is located in the heat pipe as the condensation portion, and the transmission capillary portion 112 is smaller than the cross section of the first and second capillary portions ι, 111 in cross section. The various embodiments of the creation are in terms of the width of the cross-section. Thus, a gas flow path 12 juxtaposed with the transport capillary portion 112 can be formed in the heat transfer tube as a transfer section through which the vaporized working fluid can be transferred toward the condensation portion of the heat pipe 1. In the present embodiment, the transport capillary portion 112 is placed in the middle of the tubular body 1 ,, so that the gas flow passage 12 is formed on each of the two sides of the transport capillary portion Π2.
