整合式散熱裝置Integrated heat sink

本創作係有關於整合式散熱裝置，尤指應用於散熱之整合式散熱裝置。This creation is about integrated heat sinks, especially integrated heat sinks for heat dissipation.

隨現行電子設備逐漸以輕薄作為標榜之訴求，故各項元件皆須隨之縮小其尺寸，但電子設備之尺寸縮小伴隨而來產生的熱變成電子設備與系統改善性能的主要障礙。所以業界為了有效解決電子設備內的元件散熱問題，便分別提出具有導熱效能較佳的均溫板（Vapor chamber）及熱管（Heat pipe），以有效解決現階段的散熱問題。均溫板(Vapor chamber）係呈矩型狀之殼體（或板體），其殼體內部腔室內壁面設置毛細結構，且該殼體內部填充有工作液體，並令該殼體的一側(即蒸發區)係貼設在一發熱元件(如中央處理器、南北橋晶片、電晶體、MCU或其他電子元件等)上吸附該發熱元件所產生之熱量，使液態之工作液體於該殼體之蒸發區產生蒸發轉換為汽態，將熱量傳導至該殼體之冷凝區，該汽態之工作液體於冷凝區受冷卻後冷凝為液態，該液態之工作液體再透過重力或毛細結構回流至蒸發區繼續汽液循環，以有效達到均溫散熱之效果。熱管（Heat pipe）的原理與理論架構與均溫板相同，主要是在圓管口徑的熱管內之中空部分填入金屬粉末（或是置入編織網狀的毛細或設置溝槽或複合毛細），並透過燒結之方式於該熱管之內壁形成一環狀的毛細結構，其後將該熱管抽真空並填充工作液體，最後封閉以形成熱管結構。當工作液體由蒸發部受熱蒸發後擴散至該冷凝端，並該工作液體於該蒸發部係為汽態，由該蒸發部離開後向該冷凝端擴散時逐步受冷卻冷凝轉換為液態，並且再透過毛細結構回流至該蒸發部。比較均溫板與熱管兩者只有熱傳導的方式不同，均溫板的熱傳導方式是二維的，是面的熱傳導方式（主要係大面積的均溫效果）；然而熱管的熱傳導方式是一維的熱傳導方式（主要為熱的遠端傳導）。故現今的電子元件僅配合單一的熱管或均溫板已不敷使用，因此，如何將熱管與均溫板結合在一起使用使其同時具有均溫及遠端導熱或散熱，以期大幅提升熱傳導之效率，而有效解決高功率電子元件之散熱問題，是目前業者所需改進的。With the current gradual appeal of electronic devices, all components must be reduced in size, but the heat generated by the shrinking of electronic devices has become a major obstacle to the improvement of performance of electronic devices and systems. Therefore, in order to effectively solve the problem of heat dissipation of components in electronic equipment, the industry has proposed a Vapor chamber and a heat pipe with better heat conduction performance to effectively solve the current heat dissipation problem. The Vapor chamber is a rectangular shell (or a plate body), and a capillary structure is arranged inside the inner chamber of the casing, and the inside of the casing is filled with working liquid, and one side of the casing is made. (ie, the evaporation zone) is attached to a heating element (such as a central processing unit, a north-south bridge chip, a transistor, an MCU, or other electronic components) to adsorb heat generated by the heating element, so that the liquid working liquid is in the shell. The evaporation zone of the body is converted into a vapor state, and the heat is transferred to the condensation zone of the casing. The vaporous working liquid is cooled and condensed into a liquid state in the condensation zone, and the liquid working fluid is recirculated through gravity or capillary structure. Continue to the vapor-liquid circulation to the evaporation zone to effectively achieve the effect of uniform temperature dissipation. The principle and theoretical structure of the heat pipe is the same as that of the temperature equalizing plate. The hollow part of the heat pipe of the circular pipe is filled with metal powder (or the woven mesh or the groove or composite capillary is placed). And forming an annular capillary structure on the inner wall of the heat pipe by sintering, and then vacuuming the heat pipe and filling the working liquid, and finally closing to form a heat pipe structure. When the working liquid is evaporated by the evaporation portion and evaporated to the condensation end, and the working liquid is in a vapor state in the evaporation portion, when the evaporation portion is separated and diffused toward the condensation end, it is gradually cooled and condensed into a liquid state, and then It is returned to the evaporation portion through the capillary structure. Comparing the method of heat conduction between the temperature equalization plate and the heat pipe is different. The heat conduction mode of the temperature equalization plate is two-dimensional, which is the heat conduction mode of the surface (mainly the large-area uniform temperature effect); however, the heat conduction mode of the heat pipe is one-dimensional. Thermal conduction (mainly thermal distal conduction). Therefore, today's electronic components are not suitable for use with a single heat pipe or a uniform temperature plate. Therefore, how to combine the heat pipe and the temperature equalizing plate to have both uniform temperature and remote heat conduction or heat dissipation, in order to greatly improve heat conduction. Efficiency, and effectively solve the heat dissipation problem of high-power electronic components, is currently required by the industry.

U、圖形處理器等等）時，每一發熱源的熱量透過每一第三外底面133傳遞到每一第三殼體腔室131內，在第三殼體腔室131內的工作流體135受熱轉換成蒸發工作流體135，其中一部分的蒸發工作流體135會通過第一熱管通道144從該第一貫穿口1422流至第二殼體腔室121內，待部分的蒸發工作流體135於第二殼體腔室121內冷凝轉換成液體工作流體135後，該第二殼體腔室121其內第二殼體毛細結構126上的液體工作流體135便藉由該第一開放端1421的第一熱管毛細結構145的毛細力及重力回流至第二開放端1431，然後藉由第一熱管毛細結構145與第三殼體毛細結構136連接接觸而回流至第三殼體腔室131內，同時另一部分的蒸發工作流體135會通過第二熱管通道154從該第三貫穿口1522流至第一殼體腔室111內，待部分的蒸發工作流體135於第一殼體腔室111內冷凝轉換成液體工作流體135後，該第一殼體腔室111其內第一殼體毛細結構115上的液體工作流體135便藉由該第三開放端1521的第二熱管毛細結構155的毛細力及重力回流至第四開放端1531，然後藉由第二熱管毛細結構155與第三殼體毛細結構136連接接觸而回流至第三殼體腔室131內繼續汽液循環，藉以有效達到散熱效率佳的效果。續參第6圖所示，該第一、二殼體11、12的第一、二外頂面112、122上選擇設有一散熱單元例如為散熱器21或風扇或散熱器21與風扇的組合，在一較佳實施表示設有一散熱器21。由於散熱器21具有複數鰭片以增加跟空氣接觸的面積，以使第一、二外頂面112、122上的熱量可以透過散熱器21快速散熱。藉由以上的設置，使複數個第三殼體13內的工作流體135分別經由各自連接的第一熱管14流到該第二殼體12及各自連接的第二熱管15流到該第一殼體11，然後藉由第一殼體11的第一外頂面112與第二殼體12的第二外頂面122散熱，最後從第一殼體11藉由重力及毛細力通過每一第二熱管15回流至每一第三殼體13及從第二殼體12藉由重力及毛細力通過每一第一熱管14回流至每一第三殼體13，因為重力及毛細力的雙重作用使得工作流體135的回流速度加快，汽液循環的效率提升，散熱效率隨之上升。另一方面，因為前述第一、二外頂面112、122的散熱面積大於任一第三殼體13的第三外底面133的吸熱面積，或該等第三殼體13的吸熱面積的總和，所以該等第三殼體13的工作流體135分別流到第一、二殼體11、12匯集後，藉由該第一、二殼體11、12的大散熱面積散熱，進而提升熱交換效率。請參閱第7圖，為本創作之第二實施例之局部剖面示意圖。該本實施例的結構及連結關係及其功效大致與前述第一實施例相同，故在此不重新贅述，兩者差異處在於：前述每一第二熱管15更具有至少一支撐體16，該支撐體16設於該第二熱管通道154內，且該支撐體16的一端抵接對應該第一殼體腔室111內的內壁頂側1111，其另一端抵接對應的第三殼體腔室131內的內壁底側1311。所以除了透過第二熱管15的兩端分別抵接對應該第一殼體11的內壁頂側1111與第三殼體13的內壁底側1311的結構支撐該第一殼體腔室111外，且還能透過該支撐體16來支撐該第一殼體腔室111，藉以達到雙重支撐的效果，進而有效達到增加支撐強度的效果。另外，該支撐體16設有一毛細結構161，該支撐體16在本實施例表示為一金屬柱(如銅柱)外周側上形成有該毛細結構161，該毛細結構161例如為一燒結粉末體或網目編織或溝槽或前述的組合，且該支撐體16的毛細結構161分別連接接觸第一殼體毛細結構115與第三殼體毛細結構136，使該第一殼體毛細結構115上的液體工作流體135除了藉由第二熱管毛細結構155的毛細力及重力回流至第三殼體腔室131內外，還能透過該支撐體16外周表面的燒結粉末體的毛細力及重力回流至第三殼體腔室131內，藉此有效加速液體工作流體135的回流速度的效果。並於具體實施時，該支撐體16不侷限於上述金屬柱，該支撐體16也可設計為一利用粉末冶金燒結方式成型的支撐體。請參閱第8A、9A圖，為本創作之第三實施例之立體分解與組合示意圖，並輔以參閱第8B、9B圖。該本實施例的結構及連結關係及其功效大致與前述第一實施例相同，故在此不重新贅述，兩者差異處在於：前述第一殼體11具有一第一部分116及至少一第二部分117從該第一部分116的至少一側邊一體向外延伸形成，該第一殼體11的第一部分116位於該第二殼體12的正上方處，且該第一殼體11的第一部分116與第二部分117共同界定前述第一殼體腔室111。該第二部分117在本實施例係從該第一部分116的一側邊朝遠離該第一部分116方向呈水平向外延伸構成一呈L字形狀的第一殼體11。在替代實施例，該第二部分117可為複數個第二部分117如2個第二部分117從該第一部分116的同一側邊朝同一方向向外延伸構成一呈U字形狀的第一殼體11，或是2個第二部分117從該第一部分116的兩相對側邊分別朝不同方向向外延伸構成一大致呈Z字形狀的第一殼體11，或是其他幾何形狀的第一殼體11。前述兩個第一開孔114在本實施表示開設貫穿在該第一殼體11的第一部分116其上第一外底面113上且連通該第一殼體腔室111，該第二部分117設有至少一第五開孔118，該第五開孔118開設貫穿在該第一殼體11的第二部分117上的第一外底面113上且連通該第一殼體腔室111。並該等第三殼體13在本實施例表示為三個第三殼體13，其中兩個第三殼體13位於該第二殼體12的正下方處，最後一個第三殼體13則位於第一殼體11的第二部分117的下方處。另外，前述整合式散熱裝置更包括至少一第三熱管17，該第三熱管17具有一第三管壁171、一第五延伸部172形成一第五開放端1721與一第六延伸部173形成一第六開放端1731，該第三管壁171內設有一第三熱管通道174及一第三熱管毛細結構175設於第三熱管通道174內且位在該第五開放端1721與第六開放端1731之間，且該第五、六開放端1721、1731分別位於該第三熱管17的兩端(即前端與末端)。並該第三熱管17的兩端分別插接連通相對該第一殼體11的第五開孔118與對應其中一第三殼體13(即前述最後一個第三殼體13)的第四開孔134，換言之，就是如第9B圖所示，該第三熱管17的第五延伸部172從對應的第五開孔118延伸進入該第一殼體腔室111內，使該第五開放端1721抵接該第一殼體腔室111內的一內壁頂側1111，進而令在第五開放端1721的第三熱管毛細結構175連接接觸該第一殼體腔室111內的內壁頂側1111上的第一殼體毛細結構115。另外，該第三熱管17的第六延伸部173從對應該第三殼體13(即前述最後一個第三殼體13)的第四開孔134延伸進入該第三殼體腔室131內，使該第六開放端1731抵接該第三殼體腔室131內的內壁底側1311，進而令在第六開放端1731的該第三熱管毛細結構175連接接觸該第三殼體腔室131內的內壁底側1311上的第三殼體毛細結構136。並在該第三熱管17的第五延伸部172及第六延伸部173上分別設有一第五貫穿口1722及一第六貫穿口1732貫穿該第三管壁171，該第三熱管通道174經由該第五貫穿口1722及該第六貫穿口1732連通該第一殼體腔室111及該第三殼體腔室131。其中第三熱管毛細結構175例如為燒結金屬粉末體或網目編織體或溝槽或束股纖維等，係為具有多孔隙的結構能提供毛細力驅動該工作流體135流動。所以當第三殼體13(即前述最後一個第三殼體13)的第三外底面133接觸對應的發熱源（例如CPU、MC U、圖形處理器或其他電子元件等等）時，該發熱源的熱量透過該第三外底面133傳遞到第三殼體腔室131內，在第三殼體腔室131內的工作流體135受熱轉換成蒸發工作流體135，而該蒸發工作流體135會通過第三熱管通道174從該第五貫穿口1722流至第一殼體腔室111內，待部分的蒸發工作流體135於第一殼體腔室111內冷凝轉換成液體工作流體後，該第一殼體腔室111其內第一殼體毛細結構115上的液體工作流體便藉由該第五開放端1721的第三熱管毛細結構175的毛細力及重力回流至第六開放端1731，然後藉由第三熱管毛細結構175與第三殼體毛細結構136連接接觸而回流至第三殼體腔室131內繼續汽液循環，藉以有效達到散熱效率佳的效果。因此透過本創作的第一殼體11的第二部分117從該第一部分116的至少一側邊一體向外延伸的設計，使得可以事先根據發熱源的多寡與多個發熱源在不同位置來調整該第二部分117從該第一部分116一體向外延伸的長度與延伸出去的方向位置，使得於使用上可達到更便利多元化的應用。請參閱第10A、11A圖，為本創作之第四實施例之立體分解與剖面示意圖，並輔以參閱第10B、11B圖。該本實施例的結構及連結關係及其功效大致與前述第一實施例相同，故在此不重新贅述，兩者差異處在於：前述第二殼體12具有一第一部分127及至少一第二部分128從該第一部分127的至少一側邊一體向外延伸形成，該第二殼體12的第一部分127係位於該第一殼體11下方處，且該第二殼體12的第一部分127與第二部分128共同界定前述第二殼體腔室121。該第二部分128在本實施例係從該第一部分127的一側邊朝遠離該第一部分127方向呈水平向外延伸構成一呈L字形狀的第二殼體12。在替代實施例，該第二殼體12的第二部分128可為複數個第二部分128如2個第二部分128從該第一部分127的同一側邊朝同一方向向外延伸構成一呈U字形狀的第二殼體12，或是2個第二部分128從該第一部分127的兩相對側邊分別朝不同方向向外延伸構成一大致呈Z字形狀的第二殼體12，或是其他形狀的第二殼體12。前述兩個第三開孔125在本實施表示開設貫穿在該第二殼體12的第一部分127其上第二外底面123上且連通該第二殼體腔室121，而另一個第三開孔125則開設貫穿在該第二殼體12的第二部分128上。並該等第三殼體13在本實施例表示為三個第三殼體13，其中兩個第三殼體13位於該第二殼體12的第一部分127正下方處，最後一個第三殼體13則位於第二殼體12的第二部分128的下方處。另外，該等第一熱管14在本實施例表示為三根第一熱管14，其中二根第一熱管14的兩端(即該第一、二開放端1421、1431)分別插接相對該第二殼體12的第一部分127其上兩個第三開孔125與對應兩個第三殼體13的第四開孔134，另一根第一熱管14的兩端分別插接相對該第二殼體12的第二部分128的第三開孔125與對應該第三殼體13(即最後一個第三殼體13)的第四開孔134。並另一根第一熱管14的第一熱管毛細結構145分別連接對應該第二殼體12的第二部分128內的第二殼體毛細結構126與對應該第三殼體13(即最後一個第三殼體13)的第三殼體毛細結構136。透過本創作的第二殼體12的第二部分128從該第一部分127的至少一側邊一體向外延伸的設計，使得可以事先根據發熱源的多寡與多個發熱源在不同位置來調整該第二部分128從該第一部分127一體向外延伸的長度與延伸出去的方向位置，使得於使用上可達到更便利多元化的應用。惟以上所述者，僅係本創作之較佳可行之實施例而已，舉凡利用本創作上述之方法、形狀、構造、裝置所為之變化，皆應包含於本案之權利範圍內。The
