請參照第1圖。第1圖為繪示依據本揭示一實施方式之浸入式冷卻系統10的示意圖。浸入式冷卻系統10包含冷卻槽20，冷卻槽20配置以容納冷卻液30以及浸入冷卻液30的一或多個電子裝置E。電子裝置E例如是電腦伺服器或資料儲存裝置。電子裝置E配置以自一電源接收電力而運行，並在運行過程中產生熱。冷卻液30配置以接觸電子裝置E，並從電子裝置E吸熱，以控制電子裝置E的溫度，避免電子裝置E過熱。冷卻液30為非導電液體，例如是介電液。Please refer to Figure 1. FIG. 1 is a schematic diagram illustrating an immersion cooling system 10 according to an embodiment of the present disclosure. The immersion cooling system 10 includes a cooling tank 20 configured to accommodate a cooling liquid 30 and one or more electronic devices E immersed in the cooling liquid 30 . The electronic device E is, for example, a computer server or a data storage device. The electronic device E is configured to operate by receiving power from a power source and generate heat during operation. The cooling liquid 30 is configured to contact the electronic device E and absorb heat from the electronic device E, so as to control the temperature of the electronic device E and prevent the electronic device E from overheating. The cooling liquid 30 is a non-conductive liquid, such as a dielectric liquid.

如第1圖所示，於一些實施方式中，冷卻槽20中的冷卻液30從電子裝置E吸熱而部分汽化，冷卻槽20位在冷卻液30之上的部分包含汽化的冷卻液35。浸入式冷卻系統10進一步包含冷凝器41，冷凝器41設置在冷卻槽20中，並配置以執行冷凝作業，冷凝作業包含使冷卻槽20中至少部分的汽化的冷卻液35凝結成冷卻液30。在上述二相式冷卻方法中，冷卻液30重複從電子裝置E吸熱而汽化以及被冷凝器41轉換回液態的流程，藉此協助電子裝置E散熱。As shown in FIG. 1 , in some embodiments, the cooling liquid 30 in the cooling tank 20 absorbs heat from the electronic device E and is partially vaporized, and the part of the cooling tank 20 above the cooling liquid 30 contains the vaporized cooling liquid 35 . The immersion cooling system 10 further includes a condenser 41 disposed in the cooling tank 20 and configured to perform a condensation operation including condensing at least part of the vaporized cooling liquid 35 in the cooling tank 20 into the cooling liquid 30 . In the above-mentioned two-phase cooling method, the coolant 30 absorbs heat from the electronic device E to be vaporized and is converted back to a liquid state by the condenser 41 repeatedly, thereby assisting the electronic device E to dissipate heat.

如第1圖所示，浸入式冷卻系統10進一步包含過濾系統90，過濾系統90連接冷卻槽20，並配置以從冷卻槽20中抽出冷卻液30進行過濾，以去除冷卻液30中的雜質(例如：存在冷卻槽20中或是電子裝置E中的雜質可能摻入冷卻液30)。去除冷卻液30中的雜質有助於提升浸入式冷卻系統10的效率。As shown in FIG. 1, the immersion cooling system 10 further includes a filter system 90, the filter system 90 is connected to the cooling tank 20, and is configured to extract the cooling liquid 30 from the cooling tank 20 for filtering, so as to remove impurities in the cooling liquid 30 ( For example: impurities existing in the cooling tank 20 or in the electronic device E may be mixed into the cooling liquid 30). Removing impurities from the coolant 30 helps to improve the efficiency of the immersion cooling system 10 .

如第1圖所示，過濾系統90包含管路91，管路91與冷卻槽20流體連通。管路91具有入口端A以及出口端B，入口端A以及出口端B皆連接冷卻槽20，且入口端A以及出口端B的位置皆低冷卻槽20中的冷卻液30的液面37。入口端A為冷卻液30流入管路91的一端，而出口端B為冷卻液30流出管路91的一端。As shown in FIG. 1 , the filtration system 90 includes a conduit 91 in fluid communication with the cooling tank 20 . The pipeline 91 has an inlet port A and an outlet port B. Both the inlet port A and the outlet port B are connected to the cooling tank 20 , and the positions of the inlet port A and the outlet port B are both lower than the liquid level 37 of the cooling liquid 30 in the cooling tank 20 . The inlet port A is the end where the cooling liquid 30 flows into the pipeline 91 , and the outlet port B is the end where the cooling liquid 30 flows out of the pipeline 91 .

如第1圖所示，過濾系統90還包含水泵92，水泵92設置在管路91，並配置以驅動冷卻液30流過管路91。在水泵92的驅動下，冷卻槽20中的冷卻液30從入口端A流入管路91，並從出口端B流出管路91。As shown in FIG. 1 , the filter system 90 further includes a water pump 92 disposed on the pipeline 91 and configured to drive the coolant 30 to flow through the pipeline 91 . Driven by the water pump 92 , the cooling liquid 30 in the cooling tank 20 flows into the pipeline 91 from the inlet port A, and flows out of the pipeline 91 from the outlet port B.

如第1圖所示，過濾系統90還包含濾心93，濾心93設置在管路91，並配置以過濾通過管路91的冷卻液30。濾心93可將冷卻液30中的雜質去除，提升浸入式冷卻系統10的效率。於一些實施方式中，濾心93配置以去除冷卻液30中的粒子、塑化劑以及水氣的至少一者。於一些實施方式中，濾心93包含濾網、半透膜以及活性碳的至少一者。於一些實施方式中，濾心93的兩端設置有連接器95，濾心93透過連接器95可拆裝地連接管路91，如此一來，濾心93的替換更為便利。於一些實施方式中，連接器95為快速連接(quick connect)。As shown in FIG. 1 , the filter system 90 further includes a filter element 93 disposed on the pipeline 91 and configured to filter the coolant 30 passing through the pipeline 91 . The filter element 93 can remove impurities in the cooling liquid 30 to improve the efficiency of the immersion cooling system 10 . In some embodiments, the filter element 93 is configured to remove at least one of particles, plasticizer and moisture in the cooling liquid 30 . In some embodiments, the filter core 93 includes at least one of a filter screen, a semi-permeable membrane, and activated carbon. In some embodiments, connectors 95 are provided at both ends of the filter core 93 , and the filter core 93 is detachably connected to the pipeline 91 through the connectors 95 , so that the replacement of the filter core 93 is more convenient. In some embodiments, connector 95 is a quick connect.

在二相式冷卻方法中，冷卻槽20中的冷卻液30維持在接近沸點的溫度。冷卻液30通過管路91時，管路91本身或是管路91中的元件會造成冷卻液30的壓損，此外，冷卻液30進入水泵92的低壓區也會出現壓降。此等因素造成冷卻液30的壓力降到飽和蒸汽壓以下，導致冷卻液30中形成氣泡。上述氣泡在受到高壓時(例如：通過水泵92時)可能破裂，氣泡的破裂會產生衝擊波，造成系統部件損壞或是震動/噪音等問題。In the two-phase cooling method, the cooling liquid 30 in the cooling tank 20 is maintained at a temperature close to the boiling point. When the coolant 30 passes through the pipeline 91 , the pipeline 91 itself or components in the pipeline 91 will cause a pressure loss of the coolant 30 , and in addition, a pressure drop will also occur when the coolant 30 enters the low-pressure area of the water pump 92 . These factors cause the pressure of the cooling liquid 30 to drop below the saturated vapor pressure, resulting in the formation of air bubbles in the cooling liquid 30 . The above-mentioned bubbles may burst when subjected to high pressure (for example: when passing through the water pump 92 ), and the bursting of the bubbles will generate shock waves, causing damage to system components or problems such as vibration/noise.

有鑑於上述問題，如第1圖所示，過濾系統90還包含冷卻裝置94，冷卻裝置94設置在管路91，並配置以將通過管路91的冷卻液30降溫。冷卻裝置94位於水泵92與管路91的入口端A之間，因此，流入管路91的冷卻液30先經過冷卻裝置94降溫後才進入水泵92。如此一來，可以降低冷卻液30的飽和蒸汽壓，從而降低孔蝕現象發生的機會，延長水泵92的壽命並減少震動/噪音。於一些實施方式中，冷卻裝置94配置以將冷卻液30的溫度降至管路91內的壓力所對應的飽和溫度以下。於一些實施方式中，冷卻裝置94連接水泵92的入口C。In view of the above problems, as shown in FIG. 1 , the filter system 90 further includes a cooling device 94 disposed on the pipeline 91 and configured to lower the temperature of the cooling liquid 30 passing through the pipeline 91 . The cooling device 94 is located between the water pump 92 and the inlet port A of the pipeline 91 , therefore, the cooling liquid 30 flowing into the pipeline 91 is cooled by the cooling device 94 before entering the water pump 92 . In this way, the saturated vapor pressure of the coolant 30 can be reduced, thereby reducing the chance of pitting corrosion, prolonging the life of the water pump 92 and reducing vibration/noise. In some embodiments, the cooling device 94 is configured to reduce the temperature of the cooling liquid 30 below the saturation temperature corresponding to the pressure in the pipeline 91 . In some embodiments, the cooling device 94 is connected to the inlet C of the water pump 92 .

於一些實施方式中，冷卻裝置94包含液對液或氣對液的熱交換器。於一些實施方式中，冷卻裝置94配置以循環一液體或一氣體與冷卻液30進行熱交換，以降低冷卻液30的溫度。In some embodiments, cooling device 94 includes a liquid-to-liquid or gas-to-liquid heat exchanger. In some embodiments, the cooling device 94 is configured to circulate a liquid or a gas to exchange heat with the cooling liquid 30 to reduce the temperature of the cooling liquid 30 .

如第1圖所示，於一些實施方式中，濾心93位於水泵92與管路91的出口端B之間，因此，流入管路91的冷卻液30先經過水泵92後才進入濾心93被過濾。在其他實施方式中，濾心93也可以設置在管路91的出口端B上。As shown in FIG. 1, in some embodiments, the filter element 93 is located between the water pump 92 and the outlet end B of the pipeline 91. Therefore, the coolant 30 flowing into the pipeline 91 first passes through the water pump 92 before entering the filter element 93. is filtered. In other embodiments, the filter element 93 can also be arranged on the outlet end B of the pipeline 91 .

因濾心93也會將造成冷卻液30的壓損，將濾心93設置在水泵92與管路91的出口端B之間或設置在管路91的出口端B上的做法，使冷卻液30在進入水泵92前能免於濾心93造成的額外壓損，因此，能進一步降低孔蝕現象在水泵92發生的機會。除此之外，將濾心93設置在水泵92與管路91的出口端B之間或設置在管路91的出口端B上也能減輕冷卻裝置94的負擔，因為若冷卻液30先通過濾心93再進入水泵92，冷卻裝置94因濾心93造成的額外壓損而需要將冷卻液30的降至更低的溫度來防止孔蝕現象的發生。Because the filter element 93 will also cause the pressure loss of the coolant 30, the filter element 93 is arranged between the water pump 92 and the outlet end B of the pipeline 91 or on the outlet end B of the pipeline 91, so that the coolant 30 can avoid the additional pressure loss that filter element 93 causes before entering water pump 92, therefore, can further reduce the chance that cavitation phenomenon takes place in water pump 92. In addition, the filter element 93 is arranged between the water pump 92 and the outlet port B of the pipeline 91 or on the outlet port B of the pipeline 91, which can also reduce the burden on the cooling device 94, because if the cooling liquid 30 passes through first The filter core 93 enters the water pump 92 again, and the cooling device 94 needs to reduce the temperature of the cooling liquid 30 to a lower temperature due to the additional pressure loss caused by the filter core 93 to prevent pitting from occurring.

如第1圖所示，於一些實施方式中，濾心93連接水泵92的出口D。於一些實施方式中，水泵92配置以驅動冷卻液30依序通過冷卻裝置94、水泵92以及濾心93，換言之，在冷卻液30的流動路徑上，冷卻裝置94位在水泵92之前，而水泵92位在濾心93之前。As shown in FIG. 1 , in some embodiments, the filter element 93 is connected to the outlet D of the water pump 92 . In some embodiments, the water pump 92 is configured to drive the cooling liquid 30 to pass through the cooling device 94, the water pump 92 and the filter element 93 in sequence. In other words, on the flow path of the cooling liquid 30, the cooling device 94 is located before the water pump 92, and the water pump 92 before filter 93.

如第1圖所示，於一些實施方式中，水泵92的位置低於冷卻液30在冷卻槽20中的液面37。利用水泵92與液面37的高低落差，可以增加冷卻液30的壓力，進一步降低孔蝕現象在水泵92發生的機會。於一些實施方式中，水泵92位於冷卻槽20之下。As shown in FIG. 1 , in some embodiments, the position of the water pump 92 is lower than the liquid level 37 of the cooling liquid 30 in the cooling tank 20 . Utilizing the height difference between the water pump 92 and the liquid surface 37 can increase the pressure of the cooling liquid 30 and further reduce the chance of pitting occurring in the water pump 92 . In some embodiments, the water pump 92 is located under the cooling tank 20 .

一般而言，冷卻槽20內部的氣壓與電子裝置E的負載呈正相關。具體而言，當電子裝置E的負載增加時(例如：當電子裝置E的運算量增加時)，電子裝置E在單位時間內產生較多的熱，使冷卻液30更快速地汽化，冷卻槽20的氣壓因而上升。反之，當電子裝置E的負載降低時，電子裝置E在單位時間內產生較少的熱，使冷卻液30的汽化減慢，冷卻槽20的氣壓因而下降。Generally speaking, the air pressure inside the cooling tank 20 is positively correlated with the load of the electronic device E. As shown in FIG. Specifically, when the load of the electronic device E increases (for example: when the calculation amount of the electronic device E increases), the electronic device E generates more heat per unit time, so that the cooling liquid 30 is vaporized more quickly, and the cooling tank The air pressure of 20 thus rises. Conversely, when the load of the electronic device E decreases, the electronic device E generates less heat per unit time, so that the vaporization of the cooling liquid 30 is slowed down, and thus the air pressure of the cooling tank 20 decreases.

如第1圖所示，於一些實施方式中，浸入式冷卻系統10進一步包含殼體50。殼體50覆蓋在冷卻槽20的一側以形成封閉空間56，封閉空間56具有固定的體積。在所示的實施方式中，殼體50覆蓋在冷卻槽20的頂部。於一些實施方式中，殼體50可包含金屬、玻璃、壓克力、其他合適的材料或上述材料的任意組合。As shown in FIG. 1 , in some embodiments, the immersion cooling system 10 further includes a housing 50 . The casing 50 covers one side of the cooling tank 20 to form a closed space 56 , and the closed space 56 has a fixed volume. In the illustrated embodiment, the housing 50 covers the top of the cooling tank 20 . In some embodiments, the housing 50 may comprise metal, glass, acrylic, other suitable materials, or any combination of the above materials.

如第1圖所示，於一些實施方式中，浸入式冷卻系統10進一步包含閥門61。閥門61具有兩端口分別連通封閉空間56以及冷卻槽20位在冷卻液30之上的部分(亦即，冷卻槽20中具有汽化的冷卻液35的空間)。閥門61配置以在開啟狀態與關閉狀態之間切換。當閥門61處於開啟狀態時，閥門61允許氣體在封閉空間56與冷卻槽20之間流通。當閥門61處於關閉狀態時，閥門61阻止氣體在封閉空間56與冷卻槽20之間流通。As shown in FIG. 1 , in some embodiments, the immersion cooling system 10 further includes a valve 61 . The valve 61 has two ports respectively communicating with the closed space 56 and the part of the cooling tank 20 above the cooling liquid 30 (that is, the space in the cooling tank 20 with the vaporized cooling liquid 35 ). Valve 61 is configured to switch between an open state and a closed state. When the valve 61 is in an open state, the valve 61 allows gas to flow between the enclosed space 56 and the cooling tank 20 . When the valve 61 is in the closed state, the valve 61 prevents gas from circulating between the closed space 56 and the cooling tank 20 .

承上所述，閥門61配置以因應於冷卻槽20的氣壓超過第一上限值而開啟，使氣體從冷卻槽20流向封閉空間56，藉此降低冷卻槽20的氣壓。從冷卻槽20流向封閉空間56的氣體包含汽化的冷卻液35，除此之外，亦可能包含混入汽化的冷卻液35的其他氣體，例如空氣或水蒸氣。As mentioned above, the valve 61 is configured to open when the air pressure of the cooling tank 20 exceeds the first upper limit, so that the gas flows from the cooling tank 20 to the closed space 56 , thereby reducing the air pressure of the cooling tank 20 . The gas flowing from the cooling tank 20 to the closed space 56 includes the vaporized cooling liquid 35 , and may also contain other gases mixed into the vaporized cooling liquid 35 , such as air or water vapor.

在本揭示的浸入式冷卻系統10中，冷卻槽20內部氣壓過高時，冷卻槽20的氣體排出到位於冷卻槽20一側的封閉空間56而不直接排出到大氣，如此一來，可以避免汽化的冷卻液35流失。封閉空間56收集的汽化的冷卻液35可以被回收至冷卻槽20再利用。In the immersion cooling system 10 disclosed in the present disclosure, when the internal pressure of the cooling tank 20 is too high, the gas in the cooling tank 20 is discharged to the closed space 56 on one side of the cooling tank 20 instead of being directly discharged to the atmosphere. The vaporized coolant 35 is lost. The vaporized cooling liquid 35 collected in the enclosed space 56 can be recycled to the cooling tank 20 for reuse.

如第1圖所示，於一些實施方式中，浸入式冷卻系統10進一步包含回收系統70，回收系統70配置以將封閉空間56收集的汽化的冷卻液35回收至冷卻槽20再利用。回收系統70包含冷凝器72以及回收管路74。冷凝器72設置在封閉空間56中，並配置以使封閉空間56中的汽化的冷卻液35凝結。回收管路74具有相對的兩端，一端連接封閉空間56，另一端連接冷卻槽20。回收管路74配置以導引冷凝器72凝結產生的冷卻液30流入冷卻槽20。於一些實施方式中，回收管路74包含逆止閥77，逆止閥77配置以阻止冷卻液30或汽化的冷卻液35從冷卻槽20逆流至封閉空間56。As shown in FIG. 1 , in some embodiments, the immersion cooling system 10 further includes a recovery system 70 configured to recover the vaporized cooling liquid 35 collected in the enclosed space 56 to the cooling tank 20 for reuse. The recovery system 70 includes a condenser 72 and a recovery pipeline 74 . The condenser 72 is provided in the closed space 56 and configured to condense the vaporized cooling liquid 35 in the closed space 56 . The recovery pipe 74 has two opposite ends, one end is connected to the closed space 56 and the other end is connected to the cooling tank 20 . The recovery pipeline 74 is configured to guide the cooling liquid 30 condensed by the condenser 72 to flow into the cooling tank 20 . In some embodiments, the recovery pipeline 74 includes a check valve 77 configured to prevent the cooling liquid 30 or the vaporized cooling liquid 35 from flowing back from the cooling tank 20 to the closed space 56 .

請參照第2圖，本實施方式的浸入式冷卻系統10A與第1圖所示的實施方式的一差異處，在於過濾系統90A的管路91A穿越冷卻槽20的壁面延伸進入冷卻槽20中，使得管路91A的出口端B位於冷卻槽20中。另外，在本實施方式中，過濾系統90A的濾心93設置在管路91A的出口端B上，因此，濾心93也位在冷卻槽20中，且濾心93浸入冷卻液30。Please refer to FIG. 2, a difference between the immersion cooling system 10A of this embodiment and the embodiment shown in FIG. 1 is that the pipeline 91A of the filtration system 90A extends through the wall of the cooling tank 20 and enters the cooling tank 20. The outlet end B of the pipe 91A is located in the cooling tank 20 . In addition, in this embodiment, the filter element 93 of the filter system 90A is arranged on the outlet end B of the pipeline 91A, therefore, the filter element 93 is also located in the cooling tank 20 and immersed in the cooling liquid 30 .

請參照第3圖。本實施方式的浸入式冷卻系統10B與第1圖所示的實施方式的差異處在於過濾系統90B的管路91B的出口端B位於冷卻液30在冷卻槽20中的液面37之上，因此，冷卻液30在經過過濾系統90B的過濾後從液面37之上的部分回流至冷卻槽20。於一些實施方式中，管路91B的出口端B連接在冷卻槽20的一傾斜壁面。Please refer to Figure 3. The difference between the immersion cooling system 10B of this embodiment and the embodiment shown in FIG. 1 is that the outlet end B of the pipeline 91B of the filtration system 90B is located above the liquid surface 37 of the cooling liquid 30 in the cooling tank 20, so , the cooling liquid 30 returns to the cooling tank 20 from the part above the liquid surface 37 after being filtered by the filtering system 90B. In some embodiments, the outlet B of the pipeline 91B is connected to an inclined wall of the cooling tank 20 .

綜上所述，本揭示的浸入式冷卻系統的過濾系統包含設置在水泵前的冷卻裝置，冷卻液流經冷卻裝置降溫後才進入水泵，藉此避免孔蝕現象的發生。To sum up, the filtration system of the immersion cooling system disclosed herein includes a cooling device installed in front of the water pump, and the cooling liquid flows through the cooling device to cool down before entering the water pump, thereby avoiding the occurrence of pitting corrosion.
