Description

Liquid level control equipment

本發明係提供一種液位控制設備，尤指一種具有液位高度可控性的液位控制設備。The present invention provides a liquid level control device, in particular to a liquid level control device with liquid level height controllability.

浸沒式冷卻系統可分成具有相變化的兩相式冷卻系統與沒有相變化的單相式冷卻系統，兩種浸沒式冷卻系統都需確保待冷卻元件浸泡在不導電液體內，否則待冷卻元件無法與不導電液體進行熱交換以冷卻。浸沒式冷卻系統的儲存槽內的冷卻液體的液位會隨著待冷卻元件移出儲存槽而下降；但若儲存槽內注入額外的冷卻液體、或是以體積較大的另一元件放入原儲存槽內，儲存槽內的冷卻液體的液位會超出原定標準，此液位上升現象會提高冷卻液體外洩的可能性，且過高液位易導致冷卻液體接觸浸沒式冷卻系統內的冷凝器而影響其散熱效率。Immersion cooling systems can be divided into two-phase cooling systems with phase change and single-phase cooling systems without phase change. Both immersion cooling systems must ensure that the components to be cooled are immersed in the non-conductive liquid, otherwise the components to be cooled cannot exchange heat with the non-conductive liquid for cooling. The level of the cooling liquid in the storage tank of the immersion cooling system will decrease as the component to be cooled is removed from the storage tank; however, if additional cooling liquid is injected into the storage tank, or another larger component is placed in the original storage tank, the level of the cooling liquid in the storage tank will exceed the original standard. This level increase phenomenon will increase the possibility of cooling liquid leakage, and excessively high liquid levels can easily cause the cooling liquid to contact the condenser in the immersion cooling system and affect its heat dissipation efficiency.

為了控制儲存槽內的液位，傳統的浸沒式冷卻系統係在儲存槽底部設置補液開口，且在儲存槽頂部設置排液開口。排液開口的附近設置液位上限計和液位下限計。若儲存槽內的液位低於液位下限，啟動幫浦從補液開口補充冷卻液體；若儲存槽內的液位高於液位上限，冷卻液體利用重力引導從排液開口自動排出儲存槽。然而，不同體積的待冷卻元件需要在儲存槽內設定不同的冷卻液體液位，但是液位上限計與液位下限計的位置受限於排液開口，無法提供較靈活的變通可控性。In order to control the liquid level in the storage tank, the traditional immersion cooling system is equipped with a liquid replenishment opening at the bottom of the storage tank and a liquid discharge opening at the top of the storage tank. An upper and lower liquid level gauge is set near the liquid discharge opening. If the liquid level in the storage tank is lower than the lower liquid level limit, the pump is started to replenish the cooling liquid from the liquid replenishment opening; if the liquid level in the storage tank is higher than the upper liquid level limit, the cooling liquid is automatically discharged from the storage tank from the liquid discharge opening using gravity. However, different volumes of components to be cooled require different cooling liquid levels to be set in the storage tank, but the positions of the upper and lower liquid level gauges are limited by the liquid discharge opening, and cannot provide more flexible controllability.

本發明係提供一種具有液位高度可控性的液位控制設備，以解決上述之問題。The present invention provides a liquid level control device with liquid level height controllability to solve the above-mentioned problems.

本發明之申請專利範圍係揭露一種液位控制設備，其包含有一主槽體、一儲液槽以及一連通歧管。該主槽體具有一輸送口以及一第一液位偵測器。該輸送口設置在該主槽體之一底部，該第一液位偵測器設置在該主槽體之一頂部。該儲液槽具有一液體出口、一液體入口以及一第二液位偵測器。該連通歧管設置在該主槽體與該儲液槽之間。該連通歧管包含一補液管以及一排液管。該補液管之兩端分別連接該輸送口和該液體出口。該排液管之兩端分別連接該輸送口和該液體入口。The patent application scope of the present invention discloses a liquid level control device, which includes a main tank body, a liquid storage tank and a connecting manifold. The main tank body has a delivery port and a first liquid level detector. The delivery port is arranged at a bottom of the main tank body, and the first liquid level detector is arranged at a top of the main tank body. The liquid storage tank has a liquid outlet, a liquid inlet and a second liquid level detector. The connecting manifold is arranged between the main tank body and the liquid storage tank. The connecting manifold includes a liquid replenishing pipe and a liquid draining pipe. The two ends of the liquid replenishing pipe are respectively connected to the delivery port and the liquid outlet. The two ends of the liquid draining pipe are respectively connected to the delivery port and the liquid inlet.

本發明之申請專利範圍另揭露該液位控制設備另包含有一補液幫浦以及一補液控制器。該補液幫浦設置在該補液管，用來將該儲液槽內的液體傳送到該主槽體。該補液控制器設置在該補液管，用來開啟或關閉該補液幫浦。該液位控制設備另包含有一排液幫浦以及一排液控制器。該排液幫浦設置在該排液管，用來將該主槽體內的液體傳送到該儲液槽。該排液控制器設置在該排液管，用來開啟或關閉該排液幫浦。The patent application scope of the present invention further discloses that the liquid level control device further includes a liquid replenishing pump and a liquid replenishing controller. The liquid replenishing pump is arranged in the liquid replenishing pipe, and is used to transfer the liquid in the liquid storage tank to the main tank body. The liquid replenishing controller is arranged in the liquid replenishing pipe, and is used to open or close the liquid replenishing pump. The liquid level control device further includes a liquid draining pump and a liquid draining controller. The liquid draining pump is arranged in the liquid draining pipe, and is used to transfer the liquid in the main tank body to the liquid storage tank. The liquid draining controller is arranged in the liquid draining pipe, and is used to open or close the liquid draining pump.

本發明之液位控制設備只需在主槽體底部設置一個輸送口，並利用Y型連通歧管連結主槽體與儲液槽，使得冷卻液體可以經由連通歧管的補液管與排液管在主槽體與儲液槽之間流動。由於輸送口位於主槽體的底部，故主槽體內的第一液位偵測器可依據實際需求任意調整其位置，以使液位控制設備可適用於各種體積大小的待冷卻裝置。未知體積的待冷卻裝置放入主槽體後，液位控制設備可分析第一液位偵測器與第二液位偵測器的偵測結果自動執行主槽體之排液或補液，確保主槽體與儲液槽的液位高度都符合應用需求。The liquid level control device of the present invention only needs to set a delivery port at the bottom of the main tank body, and use a Y-shaped connecting manifold to connect the main tank body and the liquid storage tank, so that the cooling liquid can flow between the main tank body and the liquid storage tank through the liquid replenishing pipe and the liquid draining pipe of the connecting manifold. Since the delivery port is located at the bottom of the main tank body, the first liquid level detector in the main tank body can be adjusted at will according to actual needs, so that the liquid level control device can be applied to various sizes of devices to be cooled. After the device to be cooled of unknown volume is placed in the main tank body, the liquid level control device can analyze the detection results of the first liquid level detector and the second liquid level detector to automatically perform the drainage or replenishment of the main tank body, ensuring that the liquid level heights of the main tank body and the liquid storage tank meet the application requirements.

請參閱第1圖與第2圖，第1圖為本發明實施例之液位控制設備10之外觀示意圖，第2圖為本發明實施例之液位控制設備10之部分元件示意圖。液位控制設備10可包含主槽體12、儲液槽14以及連通歧管16。主槽體12可具有輸送口18以及第一液位偵測器20。輸送口18較佳可設置在主槽體12之底部；主槽體12內的冷卻液體流入與流出皆通過輸送口18。第一液位偵測器20則可設置在主槽體12之頂部，用來偵測主槽體12內冷卻液體的液位變化。液位控制設備10可利用單個儲液槽14對複數個主槽體12進行補液與排液，故主槽體12之數量應相同於連通歧管16之數量，各連通管係連接儲液槽14和對應的主槽體12，且主槽體12與連通歧管16之數量不限於圖示態樣。Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram of the appearance of the liquid level control device 10 of the embodiment of the present invention, and FIG. 2 is a schematic diagram of some components of the liquid level control device 10 of the embodiment of the present invention. The liquid level control device 10 may include a main tank body 12, a liquid storage tank 14, and a connecting manifold 16. The main tank body 12 may have a delivery port 18 and a first liquid level detector 20. The delivery port 18 may preferably be disposed at the bottom of the main tank body 12; the cooling liquid in the main tank body 12 flows in and out through the delivery port 18. The first liquid level detector 20 may be disposed at the top of the main tank body 12 to detect the level change of the cooling liquid in the main tank body 12. The liquid level control device 10 can use a single liquid storage tank 14 to replenish and drain liquid from a plurality of main tank bodies 12, so the number of main tank bodies 12 should be the same as the number of connecting manifolds 16. Each connecting pipe connects the liquid storage tank 14 and the corresponding main tank body 12, and the number of main tank bodies 12 and connecting manifolds 16 is not limited to the illustrated form.

儲液槽14可具有液體出口22、液體入口24以及第二液位偵測器26。通常來說，液體出口22之位置可低於液體入口24之位置，然實際應用不限於此。連通歧管16可設置在主槽體12與儲液槽14之間。連通歧管16可包含補液管28以及排液管30。補液管28之兩端可分別連接輸送口18和儲液槽14的液體出口22。排液管30之兩端則分別連接輸送口18和儲液槽14的液體入口24。The liquid storage tank 14 may have a liquid outlet 22, a liquid inlet 24, and a second liquid level detector 26. Generally speaking, the position of the liquid outlet 22 may be lower than the position of the liquid inlet 24, but the actual application is not limited thereto. The connecting manifold 16 may be disposed between the main tank body 12 and the liquid storage tank 14. The connecting manifold 16 may include a liquid replenishing pipe 28 and a liquid draining pipe 30. The two ends of the liquid replenishing pipe 28 may be connected to the delivery port 18 and the liquid outlet 22 of the liquid storage tank 14, respectively. The two ends of the liquid draining pipe 30 may be connected to the delivery port 18 and the liquid inlet 24 of the liquid storage tank 14, respectively.

此實施例中，第一液位偵測器20可包含第一液位計32和第二液位計34，以高低落差方式分別設置在主槽體12內的不同位置，例如第一液位計32相對於主槽體12之底部的距離大於第二液位計34相對於主槽體12之底部的距離。第一液位計32可用來偵測主槽體12內的液位上限。第二液位計34則用來偵測主槽體12內的液位下限。要調整主槽體12內的液位上限及下限設定時，可以改變第一液位計32和/或第二液位計34的位置；由於輸送口18位於主槽體12的底部，故第一液位計32與第二液位計34的可變動位置不會受到輸送口18之影響。In this embodiment, the first liquid level detector 20 may include a first liquid level gauge 32 and a second liquid level gauge 34, which are respectively arranged at different positions in the main tank body 12 in a height difference manner, for example, the distance of the first liquid level gauge 32 relative to the bottom of the main tank body 12 is greater than the distance of the second liquid level gauge 34 relative to the bottom of the main tank body 12. The first liquid level gauge 32 can be used to detect the upper limit of the liquid level in the main tank body 12. The second liquid level gauge 34 is used to detect the lower limit of the liquid level in the main tank body 12. To adjust the upper and lower limit settings of the liquid level in the main tank body 12, the position of the first liquid level gauge 32 and/or the second liquid level gauge 34 can be changed; since the delivery port 18 is located at the bottom of the main tank body 12, the variable position of the first liquid level gauge 32 and the second liquid level gauge 34 will not be affected by the delivery port 18.

在其它的可能變化態樣中，第一液位偵測器20可設計成連續型液位計。欲調整主槽體12內的液位上限及下限設定時，僅需調整連續型液位計內的系統設定值，不需以手動或自動方式另行改變第一液位偵測器20的實際所在位置。In other possible variations, the first liquid level detector 20 can be designed as a continuous level gauge. When the upper and lower limits of the liquid level in the main tank 12 are to be adjusted, only the system setting value in the continuous level gauge needs to be adjusted, and the actual position of the first liquid level detector 20 does not need to be changed manually or automatically.

相應地，第二液位偵測器26可包含第一液位計36和第二液位計38，以高低落差方式分別設置在儲液槽14內的不同位置，例如第一液位計36相對於主儲液槽14之底部的距離大於第二液位計38相對於儲液槽14之底部的距離。第一液位計36可用來偵測儲液槽14內的液位上限。第二液位計38則用來偵儲液槽14內的液位下限。儲液槽14內的液位上限及下限設定的設定方式如第一液位偵測器20所述，於此不再重複說明。此外，第二液位偵測器26也可如第一液位偵測器20設計成連續型液位計。Correspondingly, the second liquid level detector 26 may include a first liquid level gauge 36 and a second liquid level gauge 38, which are respectively arranged at different positions in the liquid storage tank 14 in a height difference manner, for example, the distance of the first liquid level gauge 36 relative to the bottom of the main liquid storage tank 14 is greater than the distance of the second liquid level gauge 38 relative to the bottom of the liquid storage tank 14. The first liquid level gauge 36 can be used to detect the upper limit of the liquid level in the liquid storage tank 14. The second liquid level gauge 38 is used to detect the lower limit of the liquid level in the liquid storage tank 14. The setting method of the upper and lower limits of the liquid level in the liquid storage tank 14 is as described in the first liquid level detector 20, and will not be repeated here. In addition, the second liquid level detector 26 can also be designed as a continuous liquid level gauge like the first liquid level detector 20.

液位控制設備10可進一步包含補液幫浦40、補液控制器42、排液幫浦44以及排液控制器46。補液幫浦40與補液控制器42係設置在補液管28。排液幫浦44與排液控制器46則設置在排液管30。補液幫浦40的流動方向相反於排液幫浦44的流動方向。補液幫浦40用來將儲液槽14內的液體傳送到主槽體12，補液控制器42則用於開啟或關閉補液幫浦40。排液幫浦44用來將主槽體12內的液體傳送到儲液槽14，排液控制器46則用於開啟或關閉排液幫浦44。The liquid level control device 10 may further include a liquid replenishing pump 40, a liquid replenishing controller 42, a liquid discharge pump 44, and a liquid discharge controller 46. The liquid replenishing pump 40 and the liquid replenishing controller 42 are disposed in the liquid replenishing pipe 28. The liquid discharge pump 44 and the liquid discharge controller 46 are disposed in the liquid discharge pipe 30. The flow direction of the liquid replenishing pump 40 is opposite to the flow direction of the liquid discharge pump 44. The liquid replenishing pump 40 is used to transfer the liquid in the liquid storage tank 14 to the main tank body 12, and the liquid replenishing controller 42 is used to open or close the liquid replenishing pump 40. The drain pump 44 is used to transfer the liquid in the main tank 12 to the liquid storage tank 14 , and the drain controller 46 is used to open or close the drain pump 44 .

因此，主槽體12只在靠近底部的位置設計輸送口18，並利用Y型配管等接管方式連通於儲液槽14的液體出口22與液體入口24。連通歧管16的補液管28以及排液管30係可為Y型配管的同一側的兩管道，Y型配管的另一側的單管道即連接於主槽體12的輸送口18。主槽體12的第一液位偵測器20遠高於輸送口18，意即主槽體12的液位上限與液位下限皆高於輸送口18。再者，儲液槽14的液位下限需高於液體出口22，可避免補液幫浦40吸入空氣而通過補液管28灌進主槽體12。儲液槽14的液位上限則需相隔於儲液槽14的開口達一定距離，避免儲液槽14的液體過多而從上方開口溢出。Therefore, the main tank body 12 is only designed with a delivery port 18 near the bottom, and is connected to the liquid outlet 22 and the liquid inlet 24 of the liquid storage tank 14 by a Y-shaped pipe or other pipe connection method. The liquid replenishment pipe 28 and the liquid discharge pipe 30 connected to the manifold 16 can be two pipes on the same side of the Y-shaped pipe, and the single pipe on the other side of the Y-shaped pipe is connected to the delivery port 18 of the main tank body 12. The first liquid level detector 20 of the main tank body 12 is much higher than the delivery port 18, which means that the upper and lower limits of the liquid level of the main tank body 12 are both higher than the delivery port 18. Furthermore, the lower limit of the liquid level of the liquid storage tank 14 needs to be higher than the liquid outlet 22 to prevent the replenishment pump 40 from sucking in air and pouring it into the main tank body 12 through the replenishment pipe 28. The upper limit of the liquid level of the liquid storage tank 14 needs to be separated from the opening of the liquid storage tank 14 by a certain distance to prevent the liquid in the liquid storage tank 14 from overflowing from the upper opening due to excessive liquid.

液位控制設備10可選擇性包含運算處理器48，電連接第一液位偵測器20、第二液位偵測器26、補液控制器42以及排液控制器46。運算處理器48係分析第一液位偵測器20與第二液位偵測器26之偵測結果，輸出相應的控制指令到補液控制器42或排液控制器46以驅動補液幫浦40或排液幫浦44。運算處理器48可能是獨立的外部處理器，以有線或無線方式連接於液位控制設備10內部的電子元件。或者，運算處理器48還可能是液位控制設備10的內建處理器，其實施變化端視設計需求而定，故此不再詳加說明。The liquid level control device 10 may optionally include an operation processor 48, which is electrically connected to the first liquid level detector 20, the second liquid level detector 26, the liquid replenishment controller 42, and the liquid discharge controller 46. The operation processor 48 analyzes the detection results of the first liquid level detector 20 and the second liquid level detector 26, and outputs corresponding control instructions to the liquid replenishment controller 42 or the liquid discharge controller 46 to drive the liquid replenishment pump 40 or the liquid discharge pump 44. The operation processor 48 may be an independent external processor connected to the electronic components inside the liquid level control device 10 in a wired or wireless manner. Alternatively, the operation processor 48 may also be a built-in processor of the liquid level control device 10, and the implementation varies depending on the design requirements, so it is not described in detail.

請參閱第3圖，第3圖為本發明實施例之液位控制設備10之操作流程圖。首先執行步驟S100，關閉補液幫浦40、補液控制器42、排液幫浦44與排液控制器46，確認液位控制設備10的所有元件處於關閉狀態。接著，執行步驟S102與步驟S104，從複數個主槽體12中選擇一個主槽體12進行監控，取得此主槽體12的第一下限值。如第一液位偵測器20發出第一下限警報，執行步驟S106以取得儲液槽14的第二下限值。若第二液位偵測器26發出第二下限警報，執行步驟S108以發出主槽體12和儲液槽14之液位偏低警告。若第二液位偵測器26沒有發出第二下限警報，執行步驟S110以通過補液控制器42開啟補液幫浦40。Please refer to FIG. 3, which is an operation flow chart of the liquid level control device 10 of the embodiment of the present invention. First, execute step S100 to close the liquid replenishing pump 40, the liquid replenishing controller 42, the liquid discharge pump 44 and the liquid discharge controller 46, and confirm that all components of the liquid level control device 10 are in the closed state. Then, execute steps S102 and S104 to select a main tank body 12 from a plurality of main tank bodies 12 for monitoring and obtain the first lower limit value of this main tank body 12. If the first liquid level detector 20 issues a first lower limit alarm, execute step S106 to obtain the second lower limit value of the liquid storage tank 14. If the second liquid level detector 26 issues a second lower limit alarm, step S108 is executed to issue a low liquid level warning for the main tank 12 and the liquid storage tank 14. If the second liquid level detector 26 does not issue a second lower limit alarm, step S110 is executed to open the liquid replenishment pump 40 through the liquid replenishment controller 42.

接著，等待一段時間後執行步驟S112，再次取得主槽體12的第一下限值。若第一液位偵測器20發出第一下限警報，執行步驟S114以取得儲液槽14的第二下限值。如第二液位偵測器26沒有發出第二下限警報，則回復到步驟S110之階段。如第二液位偵測器26發出第二下限警報，執行步驟S116以關閉補液控制器42與補液幫浦40，並跳轉到步驟S108。若第一液位偵測器20沒有發出第一下限警報，表示主槽體12內的液體充足，執行步驟S118與步驟S120以關閉補液控制器42與補液幫浦40，結束主槽體12的液位控制程序，且選擇另一個主槽體12進行監控。Then, after waiting for a period of time, step S112 is executed to obtain the first lower limit value of the main tank 12 again. If the first liquid level detector 20 issues a first lower limit alarm, step S114 is executed to obtain the second lower limit value of the liquid storage tank 14. If the second liquid level detector 26 does not issue a second lower limit alarm, the process returns to step S110. If the second liquid level detector 26 issues a second lower limit alarm, step S116 is executed to turn off the liquid replenishment controller 42 and the liquid replenishment pump 40, and jump to step S108. If the first liquid level detector 20 does not send out the first lower limit alarm, it means that the liquid in the main tank 12 is sufficient, and steps S118 and S120 are executed to close the liquid replenishment controller 42 and the liquid replenishment pump 40, end the liquid level control program of the main tank 12, and select another main tank 12 for monitoring.

步驟S104之後，如第一液位偵測器20沒有發出第一下限警報，執行步驟S122以取得此主槽體12的第一上限值。若第一液位偵測器20沒有發出第一上限警報，跳轉到步驟S120以選擇另一個主槽體12進行監控。若第一液位偵測器20發出第一上限警報，執行步驟S124以取得儲液槽14的第二上限值。如第二液位偵測器26發出第二上限警報，執行步驟S126以通過排液控制器46關閉排液幫浦44，並且發出主槽體12和儲液槽14之液位偏高警告。如第二液位偵測器26沒有發出第二上限警報，執行步驟S128以通過排液控制器46開啟排液幫浦44。After step S104, if the first liquid level detector 20 does not issue a first lower limit alarm, step S122 is executed to obtain the first upper limit value of the main tank 12. If the first liquid level detector 20 does not issue a first upper limit alarm, jump to step S120 to select another main tank 12 for monitoring. If the first liquid level detector 20 issues a first upper limit alarm, step S124 is executed to obtain the second upper limit value of the storage tank 14. If the second liquid level detector 26 issues a second upper limit alarm, step S126 is executed to close the drain pump 44 through the drain controller 46, and issue a high liquid level warning for the main tank 12 and the storage tank 14. If the second liquid level detector 26 does not issue a second upper limit alarm, step S128 is executed to open the drain pump 44 through the drain controller 46.

接著，等待一段時間後執行步驟S130，再次取得主槽體12的第一上限值。如第一液位偵測器20發出第一上限警報，執行步驟S132以取得儲液槽14的第二上限值。若第二液位偵測器26沒有發出第二上限警報，則跳轉到步驟S128之階段。若第二液位偵測器26發出第二上限警報，執行步驟S134以關閉排液幫浦44與排液控制器46，並跳到步驟S126之階段。如第一液位偵測器20沒有發出第一上限警報，執行步驟S136以通過排液控制器46關閉排液幫浦44，並結束主槽體12的液位控制程序且跳轉到步驟S120以選擇另一個主槽體12進行監控。Then, after waiting for a period of time, step S130 is executed to obtain the first upper limit value of the main tank 12 again. If the first liquid level detector 20 issues a first upper limit alarm, step S132 is executed to obtain the second upper limit value of the liquid storage tank 14. If the second liquid level detector 26 does not issue a second upper limit alarm, the process jumps to step S128. If the second liquid level detector 26 issues a second upper limit alarm, step S134 is executed to close the drain pump 44 and the drain controller 46, and the process jumps to step S126. If the first liquid level detector 20 does not issue the first upper limit alarm, step S136 is executed to close the drain pump 44 through the drain controller 46, and the liquid level control program of the main tank 12 is terminated and jumps to step S120 to select another main tank 12 for monitoring.

綜上所述，本發明的液位控制設備只需在主槽體底部設置一個輸送口，並利用Y型連通歧管連結主槽體與儲液槽，使得冷卻液體可以經由連通歧管的補液管與排液管在主槽體與儲液槽之間流動。由於輸送口位於主槽體的底部，故主槽體內的第一液位偵測器可依據實際需求任意調整其位置，以使液位控制設備可適用於各種體積大小的待冷卻裝置。未知體積的待冷卻裝置放入主槽體後，液位控制設備可分析第一液位偵測器與第二液位偵測器的偵測結果自動執行主槽體之排液或補液，確保主槽體與儲液槽的液位高度都符合應用需求。在本發明的可能實施例中，本發明之液位控制設備係可應用於伺服器，該伺服器係可用於人工智慧(Artificial Intelligence，簡稱AI)運算、邊緣運算(Edge Computing)，亦可當作5G伺服器、雲端伺服器或車聯網伺服器使用。以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 In summary, the liquid level control device of the present invention only needs to set a delivery port at the bottom of the main tank body, and use a Y-shaped connecting manifold to connect the main tank body and the liquid storage tank, so that the cooling liquid can flow between the main tank body and the liquid storage tank through the liquid replenishing pipe and the liquid draining pipe of the connecting manifold. Since the delivery port is located at the bottom of the main tank body, the first liquid level detector in the main tank body can be adjusted at will according to actual needs, so that the liquid level control device can be applied to various sizes of devices to be cooled. After the device to be cooled of unknown volume is placed in the main tank body, the liquid level control device can analyze the detection results of the first liquid level detector and the second liquid level detector to automatically perform the drainage or replenishment of the main tank body, ensuring that the liquid level heights of the main tank body and the liquid storage tank meet the application requirements.
