201231905 六、發明說明： 【發明所屬之技術領域】 [0001] 本發明係有關於一種熱管結構，尤指一種穿接式熱管結 構及其製作方法。 【先前技術】 [0002] 按，熱管的結構主要包括：一封閉狀管體、佈設於該管 體内壁的一毛細組織、填注於該管體内部的一工作流體 ;使用時，熱管接觸發熱源的一端稱為是吸熱段（蒸發端 )，而另一端則稱為放熱段（冷凝端）；使用時，發熱源的 熱量被吸熱段内的工作流體吸收，導致吸熱段内的工作 流體從液態吸熱後變成氣態，呈氣態的工作流體由於熱 管内的溫度差異而流向放熱段，在放熱段釋放出熱量而 回復成液態，此液態的工作流體則沿著熱管内的毛細組 織回流至吸熱段；利用工作流體的汽液相變化及在熱管 内的循環，而將發熱源的熱量從吸熱段傳導至放熱段。 [0003] 隨著科技的日新月異，電子元件的工作效能大幅提升， 連帶地其單位時間内的發熱量也增加許多，因此，當熱 管的吸熱段内之工作流體吸收如此增多的熱量之後，工 作流體已經完全汽化，但吸熱段的汽化速率卻比放熱段 的冷凝速率大很多，導致熱管的吸熱段產生所謂的乾燒 (dry ou t)現象。為了解決上述問題，必須增加熱管尺 寸以增加工作流體的體積，但如此一來卻無法符合電子 元件曰益薄型化的需求。 [0004] 另一方面，在需要長距離熱傳導的情形中，由於氣體在 熱管内的移動速率大於工作流體在毛細組織内流動的回 100103519 表單編號A0101 第4頁/共37頁 1002006298-0 201231905 流速率，此速度差異在長距離的熱管中更加明顯，導致 長距離的熱管之乾燒現象更加嚴重，這一點是設計長距 離熱管時之瓶頸；另外，由於整根熱管中，只有吸熱段 與放熱段附近的工作流體才有吸熱蒸發與放熱冷凝的相 變，換句話說，整根熱管的實際有效工作部位僅集中在 吸熱段與放熱段二端上，導致熱管的其他部位並無法對 熱傳導的效率產生實質貢獻。 [0005] Ο [0006] [0007] [0008] Ο [0009] 因此，如何解決上述之問題點，即成為本發明人所改良 之目標。 【發明内容】 本發明之一目的，在於提供一種穿接式熱管結構，其能 夠適用於長距離的熱傳導，且具有增進的熱傳導效率。 為了達成上述之目的，本發明係提供一種穿接式熱管結 構，包括： 一第一熱管，包含一第一管體、一第一毛細組織及一第 一工作流體，該第一管體具有一中空容腔，該第一毛細 組織佈設在該中空容腔的至少一壁面上，該第一工作流 體填注在該中空容腔内；以及 一第二熱管，包令—第二管體、一第二毛細組織及一第 二工作流體，該第二熱管的部份區域被容置密封在該第 一管體的該中空容腔内，且該第二熱管的外壁和該第一 管體的内壁之間形成有一氣體通道。 本發明之另一目的，在於提供一種穿接式熱管結構的製 作方法，其能夠製作出一種穿接式熱管，以適用於長距 100103519 表單編號Α0101 第5頁/共37頁 1002006298-0 [0010] 201231905 離的熱傳導，且具有增進的熱傳導效岸。 [0011] 為了達成上述之目的，本發明係提供一種穿接式熱管結 構的製作方法，其步驟包括： [0012] a)提供一第一管體，該第一管體的二端分別成型有一第 一除氣口及一開口； [0013] b)提供一第一毛細組織，將該第一毛細組織佈設在該第 一管體的内壁； [0014] c)提供一第二熱管，自該第一管體的該開口穿入，使該 第二熱管的一部份區域容置在該第一管體内； [0015] d)提供一焊接設備，以該焊接設備對該第一管體的該開 口與該第二熱管接合處進行熔接焊合； [0016] e)提供一第一工作流體，將該第一工作流體自該第一除 氣口填入該第一管體内；以及 [0017] f)提供一除氣與焊接設備，以該除氣與焊接設備對該第 一管體進行除氣並焊接封口而形成一第一熱管。 [0018] 為了達成上述之目的，本發明係提供一種穿接式熱管結 構的製作方法，其步驟包括： [0019] a)提供一第一管體，該第一管體的二端分別成型有一開 口及一第二開口，該第一管體設有一除氣管； [0020] b)提供一第一毛細組織，將該第一毛細組織佈設在該第 一管體的内壁； [0021] c)提供一第二熱管，自該第一管體的該開口穿入，使該 100103519 表單編號A0101 第6頁/共37頁 1002006298-0 201231905 [0022] [0023] Ο [0024] [0025] G [0026] [0027] [0028] 第二熱管的一部份區域容置在該第一管體内，該第二熱 管的另一部份區域穿出該開口而形成為一第二除氣口； d) 提供一第三熱管，自該第一管體的該第二開口穿入， 使該第三熱管的一部份區域容置在該第一管體内，該第 三熱管的另一部份區域穿出該第二開口而形成為一第三 除氣口； e) 提供一焊接設備，以該焊接設備對該第一管體的該開 口與該第二熱管的接合處進行熔接焊合，且對該第一管 體的該第二開口與該第三熱管的接合處進行熔接焊合； f) 提供一工作流體，將該工作流體自該除氣管填入該第 一管體内，自該第二除氣口填入該第二管體内，且自該 第三除氣口填入該第三管體内；以及 g) 提供一除氣與焊接設備，以該除氣與焊接設備對該第 一管體、該第二管體及該第三管體進行除氣，並以該除 氣與焊接設備對該第一管體、該第二管體及該第三管體 進行除氣並焊接封口而分別形成一第一熱管、一第二熱 管及一第三熱管。 根據本發明的另一特色，提供一壓具，以該壓具對該第 一熱管和該第二熱管施以扁平加工。藉此使第二熱管在 第一熱管的内部產生支撐作用。 相較於先前技術，本發明具有以下功效： 由於一部份的第二熱管穿入第一熱管内，且在第二熱管 的外壁與第一熱管的内壁之間形成有一氣體通道，第一 100103519 表單編號A0101 第7頁/共37頁 1002006298-0 201231905 熱管的中空容腔及第二熱管内均注入有工作流體，所以 第一熱管内的工作流體與第二熱管内的工作流體分開進 行汽液相變化，所以不會發生習知單一熱管中工作流體 之乾燒現象。換句話說，第一熱管及第二熱管内的工作 流體均可以充分用於熱交換，且在第一熱管與第二熱管 内分別具有獨立的中空容腔，所以此種穿接式熱管結構 的熱傳導效能及容量比傳統單支熱管更加優異。 [0029] 根據本發明的另一特色，由於利用一壓具對該第一熱管 和該第二熱管施以扁平加工，致使第二熱管在第一熱管 的内部產生支撐作用，且呈扁狀的第一熱管比圓形的第 一熱管具有增加的接觸面積而提昇其熱傳導效率，另外 ，扁狀的第一熱管亦有助於縮減整個穿接式熱管結構的 厚度，藉此符合薄型化的需求。 【實施方式】 [0030] 有關本發明之詳細說明及技術内容，將配合圖式說明如 下，然而所附圖式僅作為說明用途，並非用於侷限本發 明。 [0031] 請參考第一圖至第十圖，其顯示本發明的第一實施例， 本發明係提供一種穿接式熱管結構1及其製作方法。以下 將依照圖式說明本發明的穿接式熱管結構1之製作方法， 藉此有助於理解本發明的穿接式熱管結構1之組成。 [0032] 本發明之穿接式熱管結構的製作方法，其步驟包括如下： [0033] a)提供一第一管體，該第一管體的二端分別成型有一第 一除氣口及一開口； 100103519 表單編號A0101 第8頁/共37頁 1002006298-0 201231905 [0034] 如第一圖所示，首先，提供一第一管體10,其為一中空 笞體J端呈開口狀；接著，對該第一管體1 〇的一端（第 圖中的左端）施以縮口以形成一第一除氣σ11。如第二 圖所不，從第—管體10遠離該第一除氣口 11的一開口 12 放入一中心棒w到該第一管體10内，此中心棒100的輪廓 與外徑被設計成對應但小於第一管體10的内壁輪廓與内 徑，藉此在第一管體10與中心棒100之間產生一間隙。 [0035] ❹ [0036] b) 提供一第一毛細組織，將該第一毛細鈕織佈設在該第 —管體的内壁； 如第二圖所不，在第一昝體丨〇與中心棒1〇〇之間的間隙内 填入一第一毛細組織13，此第一毛知組織13是由金屬粉 末製成，如第四圖所示，接著施以高溫缘結，使金屬粉 末製成的多孔狀第一毛細組織丨3黏著佈設於第一管體1〇 的至少一内壁上；當然，第一毛細組織13的材質並未侷 限於此，也可以為金屬編織網製成的彈簧狀槽溝狀、 Ο 柱狀及網狀結構。拔除中心棒100之後，使第一管體1〇内 具有中空谷腔14及遠離該第一除氣口 1丨的一開口丨2。 而且，第一管體10在鄰近該開口 12的—端成型有一第一 漸縮段121。 [0037] c) 提供一第二熱管，自該第一管體的該開口穿入，使該 第二熱管的一部份區域容置在該第一管體内； 如第五圖及第六圖所示，提供—第二管體2Q，此第二管 體20的外徑小於第—管體1Q的開σ12之内徑以便於從 第-管體1G的開σ12穿人，並使該第二管體2Q的一部份 100103519 表單編號A0101 第9頁/共37頁 1002006298-0 [0038] 201231905 區域容置在該第一管體10内；在第二管體20穿入第一管 體10之前，第二管體20的左端先密封起來，然後將右端 施以縮口而形成一第二除氣口 21 ;以習知熱管的製作方 式，從該第二除氣口 21填入金屬粉末，經過高溫燒結之 後，便得以在第二管體20内佈設多孔狀的一第二毛細組 織22(第七圖）。當然，第二毛細組織22的材質並未侷限 於此，也可以為金屬編織網製成的彈簧狀、槽溝狀、柱 狀及網狀結構。 [0039] d)提供一焊接設備，以該焊接設備對該第一管體的該開 口與該第二熱管接合處進行熔接焊合； [0040] 如第七圖所示，當第二管體20完成上述步驟並局部穿入 第一管體10的中空容腔14之後，利用一焊接設備（未顯示 )在第一管體10的開口 12施以焊接密封，致使該第一管體 10的第一漸縮段121與該第二管體20的在該開口 12焊接 封合。 [0041] e)提供一第一工作流體，將該第一工作流體自該第一除 氣口填入該第一管體内；以及f)提供一除氣與焊接設備 ，以該除氣與焊接設備對該第一管體進行除氣並焊接封 口而形成一第一熱管。 [0042] 如第八圖所示，分別從第一管體10的第一除氣口 11及第 二管體20的第二除氣口 21填入第一工作流體15與第二工 作流體23(例如：水），然後分別利用一除氣與焊接設備（ 未顯示）對第一管體10及第二管體20施以除氣，最後焊接 密封第一除氣口 11及第二除氣口 21，便形成如第九圖及 100103519 表單編號A0101 第10頁/共37頁 1002006298-0 201231905 第十圖所示的第一熱管100及第二熱管200，其中第二熱 管200的一部份區域被容置密封在該中空容腔14内，並在 該第二熱管200的外壁和該第一管體10的内壁之間形成有 一氣體通道S12。除了水之外，第一工作流體15與第二工 作流體23也可以選自由無機化合物、醇類、酮類、液態 金屬、冷煤、有機化合物及其混合物所構成的群組之一 〇 [0043] Ο 當然，可想而知，也可以先將第二管體20製作成第二熱 管200之後，再穿入第一管體10内焊接熔合，最後才對第 一管體10進行第一工作流體15的填注、除氣與焊接封口 等步驟以完成該第一熱管100，同樣可以達成本發明之穿 接式熱管結構1。 [0044] Ο 參考第九圖，以下將說明本發明的穿接式熱管結構1之熱 傳導原理。當第一除氣口 11附近的一部份第一熱管100貼 附在一發熱源（未顯示）上時，_發熱源的熱量被該部份的 第一熱管100吸收，而使該部份的第一熱管100内的第一 工作流體15吸熱而汽化蒸發，氣態的第一工作流體15流 向氣體通道S12並與第二熱管200的重疊部位進行熱交換 ，致使氣體通道S12内的氣態第一工作流體15釋放熱量而 冷凝成液態並返回位於第一除氣口 11附近的該段第一熱 管100;同時，與第一熱管100重疊的一部份第二熱管 20 0内的第二工作流體23則吸收該氣態第一工作流體15所 釋放的熱量而汽化蒸發；然後，氣態的第二工作流體23 流向第二除氣口 21附近的一部份第二熱管200並在該處釋 放熱量而冷凝回液態，藉此將發熱源的熱量從第一熱管 100103519 表單編號A0101 第11頁/共37頁 1002006298-0 201231905 100傳導到第二熱管2〇〇，最後散逸至外界。因此，倘若 在第一除氣口 21附近的一部份第二熱管2〇〇上連接複數散 熱鰭片（未顯示），便可以將發熱源的熱量從第一熱管1〇〇 陕速傳導至第二熱管2〇〇，然後透過散熱鰭片散逸到外界 〇 [0045] [0046] 參考第十一圖，其顯示本發明的第二實施例第二實施 例與第一實施例之間的差異在於：在第一實施例中第 —熱管100與第二熱管2〇〇呈圓管狀，而在第二實施例中 ^供壓具（未顯示），並以該Μ具對該第一熱管1〇〇及 第一熱官200施以扁平加工，而獲得如第一圖所示呈扁狀 的第-熱管100’肖第二熱管2〇〇’。第二實施例的製作 方法大致上與第一實施例相同，僅在最後增加一擠壓步 驟’而使第-熱管100與第二熱管2〇〇被擠壓成扁狀的第 -熱管100，與第二熱管2〇〇，。雖然第十一圖顯示第一 熱管100’與第二熱#2GG，均被壓扁，但也可以根據實 際需要而對第-熱管議，與第二熱管2Q()，之至少一部 伤施以扁平化加工。 從第十二圖可以清楚看出，第一熱管100，及第二熱管 200,經過擠壓之後，第一管體1〇,的上下外壁朝向側面 延展，而使第-管體1()，的上下外壁與„發熱源（未顯示 )的接觸®積大幅增加，如此—來，有助於提升將發熱源 的熱量從第-熱管100, „及收傳導至第二熱管2〇〇，内之 速率。另-方面，第一管體10’的上下内壁及第二熱管 200’的上下外壁經壓扁後彼此緊密接觸，亦即第二熱管 200’的上下外壁緊密接觸第一管體1〇，内的第一毛細組 100103519 表單編號A0101 第12頁/共37頁 1002006298-0 201231905 織13’ ，藉此增加整個穿接式熱管結構Γ的支撐強度。 由於經過擠壓，所以第一管體10’的左右内壁與第二熱 管200’的左右外壁之間形成有氣體通道S12’ 。 [0047] Ο [0048] 參考第十三圖及第十四圖，其顯示本發明的第三實施例 之穿接式熱管結構la，第三實施例與第二實施例之間的 差異在於：第三實施例另外包含連接第二熱管200’且遠 離第一熱管100’的一第三熱管300’ ，且第三熱管300 ’的尺寸大於第二熱管200’ ，藉此形成一種「大一小一 大」形式的穿接式熱管結構la。 在此種穿接式熱管結構la中，第一熱管100’與第二熱管 200’的製作方法與先前的實施例相同，故省略其說明以 免贅述，故僅特別說明第三熱管300’的製作方法。 [0049] ❹ 提供一第三管體30’及一第三毛細組織35，，將該第三 毛細組織35’佈設在該第三管體30’的内壁；該第三管 體30’具有一容室33’及一管口 32’ ，該第二熱管200 ’遠離該第一熱管100’的一端自該第三管體30’的該管 口 32’穿入該第三管體30’内，使該第二熱管200’的另 一部份區域被容置密封在該容室33’内，並在該另一部 份的該第二熱管200’的外壁和該第三管體30’的内壁之 間形成有一氣體通道S23’ ；該第三管體30’遠離該管口 32’的一端縮口成為一第三除氣口 31’ ，第三管體30’ 鄰近該管口 32’成型有一第三漸縮段32Γ ;以該焊接設 備對該第三管體30’及第二熱管200’進行熔接焊合，使 第三漸縮段321’與第二熱管200’在該管口 32’處焊接 封合；提供一第三工作流體36’ ，將該第三工作流體36 100103519 表單編號A0101 第13頁/共37頁 1002006298-0 201231905 ’填入該第三營體m，〜 __ 内；以該除氣與焊接設備對該第 三：體3〇’除氣並焊接該第三除氣口 31，而製成該第三 熱官3 0 0 ;提俾—厭目 ，、壓具’以該壓具對該第一熱管100， 、该第二熱管200’及兮签―狄 久成第二熱官3〇〇 之至少一部份施 以爲平化加 JL 〇 [_第二實_的穿接式熱管結構1&之主要優點在於：它進 vK申第_熱^200的長度而適合更長距離的熱傳導 ’第二熱管300’套接—部份的第二熱管·，，且第三 熱管300’與第二熱管2()『之間亦如第一實施例一般具 有氣體通道S23，；位於第三熱管300’内的-部份第二 熱管2GG’係作為雜段，在與第三熱管綱，產生熱交 換之後，再從第三熱管3〇〇，的外表面將熱量散逸至外界 ’換句話說’第二熱管3〇〇’不僅增加第二熱管2〇〇，的 熱傳導長度，而且還增加了第二熱管2〇〇，的散熱面積， 藉此大幅提升散熱效果。 考第十五圖與第十六圖，；其顯示本發明的第三實施例 之穿接式熱管結構lb，第三實:施例與第二實施例之間的 差異在於.它包含連接第一熱管1〇〇”且遠離第二熱管 200”的一第三熱管300” ，第三熱管3〇〇”的尺寸小於 第一熱官100 。換句話說，在較大的第一熱管loo”之 二端開口内分別穿入並焊接上較小的第二熱管200 ”及第 二熱管300 ’而產生出一種「小一大___小」之穿接式熱 管結構lb。 [0052] 第三實施例的製作方式敘述如下：首先提供第一管體1〇 第一管體 ，第一管體10”的中間設置一除氣管U” 100103519 表單編號A0101 第14頁/共37頁 1002006298-0 201231905 10”的二端分別成型有一開口 12”與一第二開口 16” ， 第一管體10”鄰近該第二開口 16”成型有一縮合段16Γ :接著，填入第一毛細組織13”到第一管體10”内，經 過高溫燒結之後而使第一毛細組織13”佈設於第一管體 10”的内壁；設置一第二管體20”及一第三管體30” ， 在第二管體20”與第三管體30”内佈設一第二毛細組織 22”及一第三毛細組織35” ，並使第二管體20”與第三 管體30”的自由端縮口而分別形成一第二除氣口 2Γ與 第三除氣口 31” ；從第一熱管10”的開口 12”與第二開 〇 口 16”分別穿入該第二管體20”與該第三管體30” ，並 使第二管體20”與第一漸縮段12Γ在該開口 12”焊接封 合，而第三管體30”與縮合段1 61”在該第二開口16”焊 接封合；將第一工作流體15”自該除氣管11”填入該第 一管體10”内，將第二工作流體23”自該第二除氣口 21 ”填入該第二管體20”内，將第三工作流體36”且自該 第三除氣口 3Γ填入該第三管體30”内；分別對第一管 體10”的除氣管11” 、第二熱管20”的第二除氣口 21” ^ 、第三管體30”的第三除氣口 31”施以除氣封口，而製 成一第一熱管100” 、一第二熱管20fl”及一第三熱管 300” ；最後提供一壓具，以該壓具對該第一熱管100” 、第二熱管200”及第三熱管300”之至少一部份施以扁 平加工。由於經過擠壓，所以一部份的第一管體10”的 左右内壁與第二熱管200”的左右外壁之間形成有氣體通 道s12”，另一部份的第一管體10”的左右内壁與第三熱 管300”的左右外壁之間形成有氣體通道Su”。 100103519 表單編號A0101 第15頁/共37頁 1002006298-0 201231905 [0053] 從第十六圖可以看出，當第一熱管100”接觸發熱源時， 第一熱管100”吸熱而使内部的第一工作流體氣化蒸發， 藉此加熱位於第一熱管100”内的一部份第二熱管200” 與第三熱管300” ，如此一來，第二除氣口2Γ附近的一 段第二熱管200”及第三除氣口 31”附近的一段第三熱管 300”則分別作為放熱段；換句話說，此種穿接式熱管結 構lb能夠使位於中央的發熱源之熱量快速傳導到左右二 端。 [0054] 當然，熟習此項技術者可以輕易思及，將第十五圖的穿 接式熱管結構lb再串連同樣的第一熱管100”就能夠串聯 成四段式或五段式的穿接式熱管結構。 [0055] 綜上所述，本發明已具有產業利用性、新穎性與進步性

Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a heat pipe structure, and more particularly to a piercing heat pipe structure and a method of fabricating the same. [Previous Art] [0002] According to the structure of the heat pipe, the structure of the heat pipe mainly includes: a closed pipe body, a capillary structure disposed on the inner wall of the pipe body, and a working fluid filled in the pipe body; in use, the heat pipe contacts the heat One end of the source is called the endothermic section (evaporation end), and the other end is called the exothermic section (condensation end); in use, the heat of the heat source is absorbed by the working fluid in the endothermic section, causing the working fluid in the endothermic section to After the liquid absorbs heat, it becomes gaseous. The working fluid in the gaseous state flows to the heat release section due to the temperature difference in the heat pipe, and releases heat in the heat release section to return to the liquid state. The liquid working fluid returns to the heat absorption section along the capillary structure in the heat pipe. The heat of the heat source is conducted from the heat absorption section to the heat release section by utilizing the vapor-liquid phase change of the working fluid and the circulation in the heat pipe. [0003] With the rapid development of technology, the performance of electronic components has been greatly improved, and the amount of heat generated per unit time has increased greatly. Therefore, when the working fluid in the heat absorption section of the heat pipe absorbs such increased heat, the working fluid It has been completely vaporized, but the vaporization rate of the endothermic section is much larger than the condensation rate of the exothermic section, resulting in a so-called dry ou phenomenon in the endothermic section of the heat pipe. In order to solve the above problems, it is necessary to increase the size of the heat pipe to increase the volume of the working fluid, but this does not meet the demand for thinning of the electronic components. [0004] On the other hand, in the case where long-distance heat conduction is required, since the moving rate of the gas in the heat pipe is greater than the flow of the working fluid in the capillary structure 100103519 Form No. A0101 Page 4 / Total 37 Page 1002006298-0 201231905 Flow Rate, this speed difference is more obvious in long-distance heat pipes, which leads to more serious dry burning of long-distance heat pipes, which is the bottleneck when designing long-distance heat pipes; in addition, because of the heat-absorbing section and heat release in the whole heat pipe The working fluid near the section has a phase change of endothermic evaporation and exothermic condensation. In other words, the actual effective working part of the entire heat pipe is concentrated only on the end of the heat absorption section and the heat release section, so that other parts of the heat pipe cannot be thermally conducted. Efficiency produces substantial contributions. [0005] [0009] Therefore, how to solve the above problems has become an improvement target of the present inventors.
