Description
本創作是與熱交換裝置有關，特別是指使用於具發熱體之裝置如伺服器、桌上型電腦、手提電腦、個人數位助理(PDA)、發光二極體(LED)燈具或機器設備等之中央處理器(CPU)或電子元件之一種多功型吸散熱器。This creation is related to heat exchange devices, especially for devices with heating elements such as servers, desktop computers, laptop computers, personal digital assistants (PDAs), light-emitting diode (LED) lamps or machinery, etc. A multi-function heat sink for a central processing unit (CPU) or electronic component.
一電子設備或一機器設備之吸散熱的作法已有風扇吹送空氣冷卻方式及/或熱管(heat pipe)冷卻方式，進一步有液體冷卻方式，用以應付這些設備的電子元件所產生的高熱，這些電子元件外側通常須設置一吸散熱器(heat sink)，用以迅速地將熱導引出來並散熱。The heat dissipation method of an electronic device or a machine device has a fan blowing air cooling method and/or a heat pipe cooling method, and further a liquid cooling method for coping with the high heat generated by the electronic components of the devices. A heat sink is usually provided on the outside of the electronic component to quickly guide heat and dissipate heat.
請參閱第一圖，習用一均熱板(Vapor Chamber)(91)的功效是迅速地將熱導引出來並擴大熱的分佈，用以迅速地將熱導引出，均熱板基本原理是一個內部具一微結構(毛細結構)(92)的真空腔體，當熱由熱源傳導至蒸發區時，該腔體裡面的液體工質在低真空度的環境中，便會開始產生液相變氣相的現象，此時工質吸收熱能並且體積迅速膨脹，氣相的工質會很快充滿整個腔體，當氣相工質接觸到一個比較冷的區域如該均熱板(91)之一外側面抵接一散熱鰭片(93)時便會產生凝結的現象，藉由凝結的現象釋放出在蒸發時累積的熱，凝結後的液相工質會藉由該微結構(92)的毛細現象再回到蒸發熱源處，此運作將在腔體內週而復始進行，這 就是均熱板(或稱均溫板)的運作方式。又由於工質在蒸發時微結構可以產生毛細力，所以均熱板的運作可不受重力的影響Referring to the first figure, the function of a Vapor Chamber (91) is to quickly guide the heat out and expand the heat distribution to quickly guide the heat out. The basic principle of the soaking plate is a vacuum chamber having a microstructure (capillary structure) (92). When heat is conducted from the heat source to the evaporation zone, the liquid working fluid in the cavity begins to produce a liquid phase in a low vacuum environment. The phenomenon of gas phase change, when the working medium absorbs thermal energy and the volume expands rapidly, the working medium of the gas phase will quickly fill the entire cavity, when the gas phase working medium contacts a relatively cold area such as the soaking plate (91) When one of the outer sides abuts a fin (93), condensation occurs, and the condensation accumulates the heat accumulated during evaporation. The condensed liquid phase will pass through the microstructure (92). The capillary phenomenon is returned to the evaporation heat source, and the operation will be repeated in the cavity. It is the operation mode of the soaking plate (or the soaking plate). Moreover, since the microstructure can generate capillary force when the working medium evaporates, the operation of the soaking plate can be prevented from being affected by gravity.
一冷卻系統之一吸散熱器的結構係影響該冷卻系統之散熱效率，如何更降低該吸散熱器之熱阻值(Thermal Resistance Value)係業者所努力的目標，對於一液體冷卻系統，如何有效地導引一流體在一吸散熱器內部的流動方向或/及提升該流體與該吸散熱器的熱交換效率，更是能提升該液體冷卻系統之散熱效率。The structure of one of the cooling systems absorbs the heat sink, affecting the heat dissipation efficiency of the cooling system, how to reduce the heat resistance value of the heat sink, and how effective it is for a liquid cooling system. The flow guiding direction of a fluid inside a heat sink or/and the heat exchange efficiency between the fluid and the heat sink is improved, and the heat dissipation efficiency of the liquid cooling system can be improved.
