Abstract
Description
本發明有關於一種液冷裝置,尤指一種可解決習知焊接的熱變形所產生的公差及生產成本提高的問題的液冷裝置。 The present invention relates to a liquid cooling device, in particular to a liquid cooling device that can solve the problems of tolerance and production cost increase caused by thermal deformation of conventional welding.
隨著大數據及雲端運端計算服務的需求大幅度提升,相關電子產品的散熱需求也越來越高,尤其是大型運算中心的伺服器(或稱服務器),其運算密度提高,同尺寸的空間中所產生的廢熱也大幅提升,為了降低散熱所消耗的能源,散熱器的設計漸漸由傳統使用風扇的氣冷,轉變成使用水冷頭(板)的液體方式將熱源從伺服器中帶走來水冷散熱,以解決高密度廢熱產生的問題。 As the demand for big data and cloud computing services has greatly increased, the heat dissipation requirements of related electronic products have also become higher, especially for servers (or servers) in large computing centers, whose computing density has increased. The waste heat generated in the space has also been greatly increased. In order to reduce the energy consumption for heat dissipation, the design of the radiator has gradually changed from the traditional air cooling using a fan to a liquid method using a water-cooled head (plate) to take the heat source away from the server. Water cooling is used to dissipate heat to solve the problem of high-density waste heat.
而過往使用風冷的電子產品,各個晶片所對應為單體的散熱器(Heat Sink),若系統(如伺服器)內有多個晶片亦對應多組風冷散熱器;但進而轉變成液冷或水冷型式的產品時,需要於有限的機殼空間內配置水路管線,且在狹小的空間內會影響到管線配置的主要因素有:主機板配置、水冷頭進出口方向、管線內外徑、管線最小折彎半徑等。然而習知水冷頭(板)與各部元件(水排、pump)係常使用軟性的橡皮水管串接一起構成水冷模組,但橡皮水管於安裝上易因水壓或其他問題產生接頭脫落或漏水,且又容易受時間及環境高溫影響而產生氧化龜裂導致漏水,進而造成伺服器系統內電子元件損壞的問題。 In the past air-cooled electronic products, each chip corresponds to a single heat sink (Heat Sink). If there are multiple chips in the system (such as a server), it also corresponds to multiple sets of air-cooled heat sinks; For cold or water-cooled products, it is necessary to configure water pipelines in the limited space of the casing, and the main factors that affect the pipeline configuration in a small space are: the main board configuration, the direction of the inlet and outlet of the water cooling head, the inner and outer diameters of the pipeline, The minimum bending radius of the pipeline, etc. However, the conventional water-cooling head (board) and various components (water drain, pump) are often connected in series with soft rubber water pipes to form a water-cooling module, but the rubber water pipes are likely to fall off or leak due to water pressure or other problems during installation. , And it is easy to be affected by time and high temperature of the environment to produce oxidation cracks and cause water leakage, which in turn causes the problem of damage to the electronic components in the server system.
故現有業者便改用使用金屬直管(如銅管)來取代橡皮水管來解決因水壓問題脫落及氧化滲漏問題,所以目前現有在如伺服器內部各個晶片上的水冷頭(板)是透過直銅管焊接串接一起,雖使用直銅管來串接水冷頭可解決上述漏水問題,但是直銅管在使用組裝上仍存在有待解決的技術問題,就是在組裝上因直銅管的一端與一水冷頭相焊接時已產生熱變形而形成有公差,導致所述直銅管的另一端無法再跟另一水冷頭相焊接串接起來,以致於無法組裝上系統的困境。為了避免這種情形發生,往往要設計很精確的焊接治具,以及操作人員須具備相當熟練的焊接技巧,才有辦法減少熱變形已加工出所述水冷頭,但卻會造成整體加工時間攏長及焊接成本提高的問題。 Therefore, the existing industry has switched to using metal straight pipes (such as copper pipes) to replace rubber water pipes to solve the problem of water pressure falling off and oxidation leakage. Therefore, the existing water block (plate) on each chip inside the server is Welding straight copper pipes together in series, although the use of straight copper pipes to connect the water cooling head in series can solve the above-mentioned water leakage problem, there are still technical problems to be solved in the use and assembly of straight copper pipes. When one end is welded with a water-cooled head, thermal deformation has been generated and a tolerance is formed. As a result, the other end of the straight copper pipe can no longer be welded and connected with another water-cooled head in series, so that the system cannot be assembled. In order to avoid this situation, it is often necessary to design a very precise welding jig, and the operator must have quite skilled welding skills in order to reduce the thermal deformation. The water block has been processed, but it will cause the overall processing time to be shortened. The problem of increasing welding costs.
雖透過焊接治具及熟練焊接的操作人員可加工出所述水冷頭,但卻要面臨一難題,就是每一伺服器內的各晶片之間的距離、高低及孔位仍有公差或落差,因直銅管本身彈性差並無足夠的彈性消去各部件的公差,導致加工後的水冷頭無法適度的組裝在對應的各晶片上,也基於這個因素,使得目前銅管焊接類的產品無法有效地被廣泛應用在伺服器水冷產品之中。 Although the water block can be processed by welding jigs and skilled welding operators, it still faces a problem, that is, the distance, height, and hole positions between the chips in each server still have tolerances or gaps. Due to the poor elasticity of the straight copper tube itself, there is not enough flexibility to eliminate the tolerances of each component, resulting in the processed water block cannot be properly assembled on the corresponding chips. Also based on this factor, the current copper tube welding products cannot be effective. Ground is widely used in server water cooling products.
先前技術缺點為如下: The disadvantages of the prior art are as follows:
1.目前焊接工藝仍會熱應力及熱變形發生,所以焊接組成後的水冷頭本身會產生大量變形而會有公差,但因直銅管本身彈性差無法吸收該公差,以導致該直通管的兩端無法跟兩水冷頭相焊接串接一起,進而造成水冷頭無法安裝在系統內的問題。 1. The current welding process will still cause thermal stress and thermal deformation, so the water block itself after welding will produce a large amount of deformation and will have tolerances. However, due to the poor elasticity of the straight copper pipe itself, the tolerance cannot be absorbed, which leads to the failure of the straight pipe. The two ends cannot be welded and connected in series with the two water cooling heads, which causes the problem that the water cooling head cannot be installed in the system.
2.操作人員須具備有良好火焰焊接能力及焊接治具,才能減少熱變形產生,導致焊接工時增加、生產效率不佳及成本提高的問題,且還無法適用在各種不同客戶端的液冷的系統中。 2. The operator must have good flame welding capabilities and welding fixtures to reduce thermal deformation, resulting in increased welding hours, poor production efficiency and increased costs, and it cannot be applied to liquid-cooled systems of various clients. In the system.
