[0077] Please refer to Figure 1 and Figure 3 , Figure 1 A schematic diagram of the structure of the first working state of the immersion cooling system 1 in some embodiments; Figure 3 For Figure 1 The immersion cooling system 1 and the block diagram of the control circuit thereof are shown in FIG. Figure 1, an immersion cooling system 1, which includes a working tank 10, a buffer tank 20 and a connection control component 30. The working tank 10 is suitable for accommodating a working fluid (which may be a liquid working fluid and / or a gas working fluid; when the state of the fluid 12 is not specifically described herein, the fluid 12 refers to the liquid working fluid). The working tank 10 has a working tank gas phase area V1 and a working tank liquid phase area L1. The working tank gas phase area V1 is used to accommodate a gas-phase mixed fluid, including a gas-phase working fluid and a gas that may exist (such as water vapor), and the working tank liquid phase area L1 is used to accommodate a liquid working fluid. The buffer tank 20 is suitable for accommodating a working fluid (which may be a liquid working fluid and a gas working fluid; when the state of the fluid 22 is not specifically described herein, the fluid 22 refers to a liquid working fluid). The buffer tank 20 has a buffer tank gas phase area V2 and a buffer tank liquid phase area L2. The buffer tank gas phase area V2 is used to accommodate a gas-phase mixed fluid, including a gas-phase working fluid and a gas that may exist (such as water vapor). The buffer tank liquid phase zone L2 is used to accommodate the liquid phase working fluid. The connection control component 30 includes a first control component 31 (including a first pipeline 310 and a first pump 312) and a second control component 32 (including a second pipeline 320 and a second valve 321). When the first pump 312 is actuated, the fluid 12 in the working tank liquid phase zone L1 is selectively transported to the buffer tank liquid phase zone L2 through the first pipeline 310, or the fluid 22 in the buffer tank liquid phase zone L2 is transported to the working tank liquid phase zone L1 (detailed later). When the second valve 321 is actuated, the working tank gas phase zone V1 and the buffer tank gas phase zone V2 are selectively connected through the second pipeline 320 (detailed later), so as to selectively transport the gas phase mixed fluid in the working tank gas phase zone V1 to the buffer tank gas phase zone V2, or transport the gas phase mixed fluid in the buffer tank gas phase zone V2 to the working tank gas phase zone V1. Thus, by selectively transporting the fluid 12 in the working tank liquid phase zone L1 to the outside of the working tank 10 (e.g., the buffer tank liquid phase zone L2), and by selectively transporting the fluid 22 in the buffer tank liquid phase zone L2 to the inside of the working tank 10 (e.g., the working tank liquid phase zone L1), the fluid 12 in the working tank 10 can reduce the temperature of the fluid 12 in the working tank 10 through such transport, and even reduce the overall temperature of the working tank 10. Therefore, in some embodiments, the overall temperature of the working tank 10 can be quickly reduced, thereby reducing the waiting cooling time required for the working tank 10 (compared with the waiting cooling time required for the existing working tank), thereby reducing the cooling cost.

[0078] Please continue to refer to Figure 1 In some embodiments, the working tank 10 includes a working tank sensing component 13, and the communication control component 30 further includes a control unit 34 (see Figure 1 and Figure 3). The working tank sensing component 13 is used to sense the temperature of the working tank liquid phase zone L1 and the pressure of the working tank gas phase zone V1. The control unit 34 is used in the maintenance mode (to be described in detail later) and when the temperature of the working tank liquid phase zone L1 is higher than the preset temperature value, the first pump 312 is actuated to transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2 (to be described in detail later), and when the pressure of the working tank gas phase zone V1 does not meet the preset pressure range, the second valve component 321 is actuated to connect the working tank gas phase zone V1 and the buffer tank gas phase zone V2 (to be described in detail later). Thus, by monitoring the temperature of the fluid 12 in the working tank 10, and when the temperature of the fluid 12 is abnormal (for example, the temperature is too high), the fluid 12 in the working tank 10 can be selectively transported to the buffer tank 20.

[0079] In addition, with the assistance of monitoring the pressure of the working tank 10, when the pressure is abnormal (for example, not falling within the preset pressure range), the working tank gas phase zone V1 of the working tank 10 can be selectively connected to the buffer tank gas phase zone V2 of the buffer tank 20, thereby quickly balancing the pressure between the two tank bodies (i.e., the working tank 10 and the buffer tank 20).

[0080] Please continue to refer to Figure 1 In some embodiments, the working tank 10 includes a working tank body 11, which is suitable for accommodating a fluid 12 (liquid working fluid), a gaseous mixed fluid (including a gaseous working fluid and possibly existing gas (such as water vapor)) and a component to be cooled 15. The working fluid (or heat transfer fluid) is a non-conductive fluid. Under normal circumstances (i.e., below the boiling point of the working fluid), the working fluid is a liquid working fluid (i.e., fluid 12); and because the boiling point of the working fluid is lower than or slightly equal to the temperature of the component to be cooled 15, when the component to be cooled 15 is immersed in the liquid working fluid, the liquid working fluid will quickly reach the critical boiling point due to absorbing the heat of the component to be cooled 15, and then vaporize into a gaseous working fluid. The component to be cooled 15 can be any component with a temperature higher than that of the working fluid. For example, the component to be cooled 15 is one or more components to be cooled 15. For another example, the component to be cooled 15 can be a single rack-mounted servo unit, or a cabinet-type servo system including multiple rack-mounted servo units.

[0081] Please continue to refer to Figure 1In some embodiments, the gas phase zone V1 of the working tank includes an air sub-zone V11 and a vapor sub-zone V12. The air sub-zone V11 is suitable for accommodating air, such as water vapor and / or other common atmospheric gases. The vapor sub-zone V12 is suitable for accommodating a vapor-phase working fluid. Since gases are less susceptible to spatial confinement, the air sub-zone V11 does not exclude the possibility of containing some vapor-phase working fluid, and the vapor sub-zone V12 does not exclude the possibility of containing air. The boundary between the air sub-zone V11 and the vapor sub-zone V12 is not a fixed boundary; instead, the boundary between the air sub-zone V11 and the vapor sub-zone V12 may rise or fall with the pressure, temperature and / or the relative proportion of air and vapor-phase working fluid inside the working tank 10 (for example, along the lines such as Figure 1 In some embodiments, the specific gravity of the gas phase working fluid is higher than that of air, so the air sub-region V11 may be located above the vapor sub-region V12 (as can be seen in Figure 1 ). For example, in Figure 1 In the working tank 10 , the interior is divided into an air sub-zone V11 , a vapor sub-zone V12 , and a working tank liquid phase zone L1 in sequence from top to bottom (ie, from the +Z direction to the −Z direction).

[0082] Please continue to refer to Figure 1 In some embodiments, the buffer tank 20 includes a buffer tank body 21, and the buffer tank body 21 is suitable for accommodating a fluid 22 (liquid phase working fluid) and a gas phase mixed fluid (including a gas phase working fluid and a gas (such as water vapor) that may exist). The working fluid of the buffer tank body 21 may have physical and chemical properties that are compatible with the working fluid of the working tank body 11; the implementation of the working fluid can be referred to above and will not be described in detail here. Therefore, in some embodiments, when the buffer tank 20 is selectively connected to the working tank 10, the working fluid of the buffer tank 20 and the working fluid of the working tank 10 may be compatible with each other and flow freely between the buffer tank 20 and the working tank 10.

[0083] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the buffer tank 20 further includes a dehumidification component 25, and the dehumidification component 25 corresponds to the buffer tank gas phase zone V2. For example, the dehumidification component 25 may be located at the top of the buffer tank body 21 to correspond to the configuration in the buffer tank gas phase zone V2. The dehumidification component 25 may be various devices with the function of removing water vapor. Therefore, in some embodiments, the water vapor in the gas-phase mixed fluid in the buffer tank gas phase zone V2 can also be removed through the dehumidification component 25 to avoid damage to the buffer tank 20 (or even the working tank 10). Based on this, in some embodiments, it can also avoid affecting the overall cooling efficiency of the immersion cooling system 1. Figure 1 and Figure 3 According to some embodiments, the dehumidification component 25 can also selectively communicate with the control unit 34 to return a signal to the control unit 34.

[0084] Please continue to refer to Figure 1 In some embodiments, the working tank body 11 has a plurality of interfaces, such as a first interface P1, a second interface P2 and a third interface P3 (see Figure 7 and Figure 8 , which will be described in detail later). These interfaces can be used to connect the working tank 10 (e.g., the working tank body 11) and the buffer tank 20 (e.g., the buffer tank body 21). In some embodiments, according to the configuration of the working tank gas phase region V1 and the working tank liquid phase region L1, the above-mentioned multiple interfaces have a specific configuration relationship (e.g., Figure 1 Configuration height relationship in the Z direction). For example, Figure 1 , the first interface P1 is configured at the bottom of the working tank body 11 and adjacent to the working tank liquid phase zone L1, so as to transport the fluid 12 in the working tank liquid phase zone L1 to the outside of the working tank body 11, or to transport other fluids (such as the fluid 22 in the buffer tank liquid phase zone L2) to the working tank liquid phase zone L1. For another example, the second interface P2 can be configured at the top of the working tank body 11 and adjacent to the working tank gas phase zone V1, so as to transport the gas-phase mixed fluid in the working tank gas phase zone V1 to the outside of the working tank body 11, or to transport other fluids (such as the gas-phase mixed fluid in the buffer tank gas phase zone V2) to the working tank gas phase zone V1. In some embodiments, for example Figure 1 In the Z direction, the second port P2 is located at a higher height than the first port P1. In some embodiments, the second port P2 may be configured to be adjacent to the air sub-region V11 (see Figure 1 ) or steam sub-area V12. For example, in Figure 1 The second port P2 is disposed at the top of the working tank body 11 and adjacent to the air sub-region V11 to transport the gas contained in the air sub-region V11 to the outside of the working tank body 11 .

[0085] Please continue to refer to Figure 1In some embodiments, one end of the first pipeline 310 is directly connected to the working tank liquid phase area L1 through the first interface P1, and the other end of the first pipeline 310 is directly connected to the buffer tank liquid phase area L2. Therefore, the fluid 12 in the working tank liquid phase area L1 and the fluid 22 in the buffer tank liquid phase area L2 can be directly transported between the working tank liquid phase area L1 and the buffer tank liquid phase area L2 through the first interface P1. Or in some embodiments, one end of the first pipeline 310 can be indirectly connected to the working tank liquid phase area L1; for example, one end of the first pipeline 310 can selectively extend from the working tank gas phase area V1 to the inside of the working tank 10 to connect with the working tank liquid phase area L1. Or in some embodiments, the other end of the first pipeline 310 can be indirectly connected to the buffer tank liquid phase area L2; for example, the other end of the first pipeline 310 can selectively extend from the buffer tank gas phase area V2 to the inside of the buffer tank 20 to further connect with the buffer tank liquid phase area L2. The two ends of the first pipeline 310 are respectively connected to the working tank liquid phase area L1 and the buffer tank liquid phase area L2, and the connection mode can be independent of direct connection or indirect connection.

[0086] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the first pump 312 is located in the first pipeline 310 and is disposed between the working tank 10 and the buffer tank 20. The first pump 312 is a device that can increase the fluid pressure so that the fluid 12 and the fluid 22 have a greater propulsion force. The first pump 312 is connected to the control unit 34 in communication to receive a control signal from the control unit 34. Therefore, through the first pump 312 actuated by the control unit 34, the fluid 12 and / or the fluid 22 can be moved along any pipeline direction of the first pipeline 310 (for example, Figure 1 The first direction D1 and Figure 2 In other words, in some embodiments, even if the communication control component 30 includes only a single pipeline (ie, the first pipeline 310, see Figure 1 ), but the fluid 12 in the working tank liquid phase area L1 can be transported to the buffer tank liquid phase area L2 through the first pipeline 310, and the fluid 22 in the buffer tank liquid phase area L2 can also be transported to the working tank liquid phase area L1 through the same first pipeline 310. Thus, it is possible to avoid setting up more pipelines, which helps to reduce the installation space required for the overall system.

[0087] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the first control assembly 31 further includes a first valve 311, which is located in the first pipeline 310 and is configured between the working tank 10 and the buffer tank 20. The first valve 311 can be located between the working tank 10 and the first pump 312 (see Figure 1), or between the first pump 312 and the buffer tank 20. The first valve member 311 may be any device having a valve function, such as a non-return valve (check valve). The first valve member 311 is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. Therefore, through the first valve member 311 actuated by the control unit 34, the working tank liquid phase region L1 and the buffer tank liquid phase region L2 may be more controlled to be connected or disconnected with each other (for example, the first valve member 311 is used to be selectively closed under the control of the control unit 34 to prevent the fluid 12 and / or the fluid 22 from flowing between the working tank liquid phase region L1 and the buffer tank liquid phase region L2), and the fluid 12 and / or the fluid 22 may also be more controlled to be transported between the working tank liquid phase region L1 and the buffer tank liquid phase region L2 through the first pipeline 310.

[0088] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the first control assembly 31 further includes a first filter 313, which is located in the first pipeline 310 and is disposed between the working tank 10 and the buffer tank 20. The first filter 313 can be located between the working tank 10 and the first pump 312 (see Figure 1 ), or between the first pump 312 and the buffer tank 20. The first filter 313 can be any device that has the function of filtering impurities and / or removing moisture. Therefore, the first filter 313 can also remove impurities and moisture in the fluid 12 and / or the fluid 22, thereby avoiding damage to the working tank 10 and / or the buffer tank 20, and avoiding affecting the overall cooling performance of the immersion cooling system 1. Figure 1 and Figure 3 According to some embodiments, the first filter element 313 may also be selectively communicatively connected to the control unit 34 to transmit a signal back to the control unit 34 .

[0089] Please continue to refer to Figure 1 In some embodiments, one end of the second pipeline 320 is directly connected to the working tank gas phase zone V1 through the second interface P2, and the other end of the second pipeline 320 is directly connected to the buffer tank gas phase zone V2. Therefore, the air in the air sub-zone V11 and the gas-phase mixed fluid in the buffer tank gas phase zone V2 can be transported between the air sub-zone V11 and the buffer tank gas phase zone V2. Based on this, when there is a pressure difference between the working tank gas phase zone V1 (or the air sub-zone V11) and the buffer tank gas phase zone V2, the pressure difference will drive the gas-phase mixed fluid in the working tank 10 and / or the buffer tank 20 to flow along at least one pipeline direction of the second pipeline 320 (for example Figure 2 The gas phase region V1 (or the air sub-region V11) of the working tank and the gas phase region V2 of the buffer tank can be pressure balanced.

[0090] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the second valve member 321 is located in the second pipeline 320 and is configured between the working tank 10 and the buffer tank 20. The second valve member 321 can be various devices with controllable valve functions, such as a check valve. The second valve member 321 is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. Therefore, in some embodiments, through the second valve member 321 actuated by the control unit 34, the working tank gas phase region V1 and the buffer tank gas phase region V2 can be more controlled to be connected or disconnected (for example, the second valve member 321 is used to be selectively closed under the control of the control unit 34 to prevent the gas-phase mixed fluid from flowing between the working tank gas phase region V1 and the buffer tank gas phase region V2), and the gas-phase mixed fluid can also be more controlled to be transported between the working tank gas phase region V1 and the buffer tank gas phase region V2 through the second pipeline 320.

[0091] In some embodiments, the second control component 32 further includes a second pump (not shown), which can be located in the second pipeline 320 and configured between the working tank 10 and the buffer tank 20. The second pump can be any device that can increase the fluid pressure so that the gas-phase mixed fluid has a greater propulsion force. The second pump is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. Therefore, in some embodiments, the gas-phase mixed fluid can be moved along any pipeline direction of the second pipeline 320 (for example, Figure 2 The second direction D2, D2′) is more controlled and transported inside the second pipeline 320.

[0092] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the second control assembly 32 further includes a dehumidifier 322, which is located in the second pipeline 320 and disposed between the working tank 10 and the buffer tank 20. The dehumidifier 322 can be located between the working tank 10 and the second valve 321, or between the second valve 321 and the buffer tank 20 (see Figure 1 ). The dehumidifier 322 can be any device that has the function of removing moisture. Therefore, in some embodiments, the dehumidifier 322 can also remove moisture from the gas phase mixed fluid in the gas phase region V2 of the buffer tank, thereby avoiding damage to the buffer tank 20 (or even the working tank 10) and avoiding affecting the overall cooling efficiency of the immersion cooling system 1. Figure 1 and Figure 3 According to some embodiments, the dehumidification unit 322 may also be selectively communicatively connected to the control unit 34 to transmit signals back to the control unit 34 .

[0093] In addition, please continue to refer to Figure 1In some embodiments, the temperature of the second control component 32 (which may include the second pipeline 320, the second valve 321, and the dehumidification unit 322) is higher than or equal to the boiling point or dew point of the gas-phase mixed fluid (for example, higher than or equal to the boiling point or dew point of water, and higher than the boiling point or dew point of the working fluid), so as to prevent the water vapor in the gas-phase mixed fluid from being condensed into water first during the process of transporting the gas-phase mixed fluid in the second pipeline 320. Therefore, in some embodiments, by adjusting the temperature of the second control component 32, it is possible to prevent the condensed water from reacting with the gas-phase mixed fluid in the second pipeline 320, and to prevent the final change in the characteristics of the fluid 12 and / or the fluid 22.

[0094] Please also refer to Figures 1 to 3 , Figure 2 For Figure 1 FIG. 1 is a schematic diagram of the structure of the immersion cooling system 1 in the second working state. In some embodiments, the working tank sensing component 13 includes a working tank temperature sensor 130, which is used to sense the temperature of the working tank liquid phase area L1 (for example, the temperature of the fluid 12), and transmit the temperature of the working tank liquid phase area L1 to the control unit 34. The working tank temperature sensor 130 can be various devices with temperature sensing functions (for example, a thermometer) and is connected to the working tank body 11 to sense the temperature of the working tank liquid phase area L1. The control unit 34 obtains the temperature of the working tank liquid phase area L1 through the working tank temperature sensor 130, and further uses the temperature as a judgment condition for whether the fluid 12 in the working tank liquid phase area L1 needs to be transported to the buffer tank liquid phase area L2 (and / or whether the fluid 22 in the buffer tank liquid phase area L2 needs to be transported to the working tank liquid phase area L1). In this way, it is possible to avoid the temperature abnormality of the working tank 10 affecting the cooling efficiency of the fluid 12.

[0095] For example, the control unit 34 may set a preset temperature (which may be a preset temperature value or a preset temperature range) according to the physical properties of the working fluid (such as boiling point or dew point), and the preset temperature value may include at least one of an upper temperature limit and a lower temperature limit. Therefore, when the control unit 34 determines through the working tank temperature sensor 130 that the temperature of the working tank liquid phase region L1 is greater than or equal to the upper temperature limit, the control unit 34 determines that the "maintenance mode" should be entered (see Figure 4 In some embodiments, when the control unit 34 determines that the temperature of the working tank liquid phase region L1 is lower than the lower limit of the temperature, the control unit 34 determines that the "maintenance mode" should be terminated or other modes should be entered, such as the "cover opening mode" (see Figure 4 In the cover opening mode, the immersion cooling system 1 can automatically or manually open the cover of the working tank 10 to detect or replace the internal components of the working tank 10 (such as the component to be cooled 15 (see Figure 1 )).

[0096] Please continue to refer to Figures 1 to 3 In some embodiments, the working tank sensing assembly 13 includes a working tank pressure sensor 131, which is used to sense the pressure of the working tank gas phase region V1 and transmit the pressure of the working tank gas phase region V1 to the control unit 34. The working tank pressure sensor 131 can be various devices with pressure sensing functions (such as a pressure gauge) and is connected to the working tank body 11 to sense the pressure of the working tank gas phase region V1. The control unit 34 obtains the pressure of the working tank gas phase region V1 through the working tank pressure sensor 131. The pressure of the working tank 10 transmitted back by the working tank pressure sensor 131 is directly related to the dew point temperature (dew point) of the gas phase working fluid condensing into the liquid phase working fluid. Therefore, the pressure of the working tank 10 can be further used as a judgment condition for whether to connect or not connect the working tank 10 (such as the working tank gas phase region V1) and the buffer tank 20 (such as the buffer tank gas phase region V2). Therefore, in some embodiments, it is possible to avoid the abnormal pressure of the working tank 10 affecting the cooling efficiency of the fluid 12, and even more effectively and quickly reduce the temperature of the fluid 12 in the working tank liquid phase region L1.

[0097] For example, the control unit 34 may set a preset pressure range according to the physical properties of the working fluid (e.g., boiling point or dew point) or the operating procedure, and the preset pressure range includes an upper pressure limit and a lower pressure limit to form a preset range. Based on this, in some embodiments, when the pressure of the working tank gas phase region V1 reported back by the working tank pressure sensor 131 falls within the preset pressure range, the control unit 34 determines that the pressure of the working tank gas phase region V1 is normal and there is no need to connect the working tank 10 (e.g., the working tank gas phase region V1) and the buffer tank 20 (e.g., the buffer tank gas phase region V2).

[0098] In some embodiments, when the pressure of the working tank gas phase zone V1 reported back by the working tank pressure sensor 131 does not meet the preset pressure range (for example, the pressure of the working tank gas phase zone V1 is judged to be higher than the upper pressure limit or lower than the lower pressure limit), the control unit 34 determines that the pressure of the working tank gas phase zone V1 is abnormal (for example, too high or too low) and should control the connection between the working tank 10 (for example, the working tank gas phase zone V1) and the buffer tank 20 (for example, the buffer tank gas phase zone V2). Therefore, in some embodiments, the gas phase mixed fluid in the buffer tank gas phase zone V2 (higher pressure) is transported to the working tank gas phase zone V1 (lower pressure), or the gas phase mixed fluid in the working tank gas phase zone V1 (higher pressure) is transported to the buffer tank gas phase zone V2 (lower pressure), thereby balancing the pressure of the two tank bodies (i.e., the working tank 10 and the buffer tank 20).

[0099] Please continue to refer to Figures 1 to 3In some embodiments, the working tank sensing assembly 13 includes a working tank liquid level sensor 132, which is used to sense the liquid level H1 of the fluid 12 in the working tank liquid phase area L1, and transmit the liquid level H1 of the fluid 12 back to the control unit 34. The working tank liquid level sensor 132 can be various devices with liquid level sensing functions (such as a liquid level sensor) and is connected to the working tank body 11 to sense, for example, the liquid level H1 of the fluid 12 in the working tank liquid phase area L1. The control unit 34 obtains the liquid level H1 of the fluid 12 through the working tank liquid level sensor 132, and further uses the liquid level H1 as a judgment condition for whether to start or stop transporting the fluid 12 in the working tank liquid phase area L1 and / or the fluid 22 in the buffer tank liquid phase area L2. Therefore, in some embodiments, it is possible to avoid the abnormal liquid level of the working tank 10 affecting the cooling efficiency of the fluid 12, and even more effectively and quickly reduce the temperature of the fluid 12 in the working tank liquid phase area L1.

[0100] For example, the control unit 34 may set a preset liquid level range according to the operating procedure or device specification. The preset liquid level range may include, for example, a first preset height value S1 (see Figure 1 ) and the second height preset value S2 (see Figure 1 ; to be described in detail later). The first preset height value S1 can be set to be lower than the second preset height value S2. In some embodiments, when the control unit 34 determines through the working tank liquid level sensor 132 that the liquid level H1 of the fluid 12 is lower than the first preset height value S1, the control unit 34 determines that it is necessary to enter the "backfill mode" (see Figure 5 , which will be described in detail later), so as to transport the fluid 22 in the buffer tank liquid phase area L2 to the working tank liquid phase area L1, and ensure that the liquid level H1 of the fluid 12 is at least higher than the first preset height value S1 (even higher than the second preset height value S2).

[0101] For another example, the preset range of the liquid level may further include a third preset height value (not shown), and the third preset height value is higher than the second preset height value S2, and the second preset height value S2 is higher than the first preset height value S1. In some embodiments, when the control unit 34 determines through the working tank liquid level sensor 132 that the liquid level H1 of the fluid 12 is higher than the third preset height value, the control unit 34 determines that it is necessary to enter the "circulation mode" (see Figure 6 , which will be described in detail later), to transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2, and ensure that the liquid level H1 of the fluid 12 is at least lower than the third height preset value (for example, lower than the second height preset value S2 but higher than the first height preset value S1).

[0102] Please continue to refer to Figure 1 and Figure 2In some embodiments, the above-mentioned preset range of the liquid level can be configured with reference to the position heights of the multiple interfaces P1 and P2 of the working tank 10.

[0103] For example, the above-mentioned preset range of liquid level may include a first preset height value S1, which is higher than the position height of the first interface P1; that is, the position height of the first interface P1 is lower than or slightly equal to the first preset height value S1. Therefore, in some embodiments, by monitoring the liquid level H1 of the fluid 12 in the working tank liquid phase area L1, the lowest possible liquid level of the fluid 12 in the working tank liquid phase area L1 can be controlled to be equal to or slightly lower than the first preset height value S1, and will not be lower than the position height of the first interface P1. Therefore, in some embodiments, it can be ensured that at least the fluid 12 with a liquid level H1 higher than the first interface P1 is accommodated in the working tank liquid phase area L1, so that the first pipeline 310 can be normally filled with the fluid 12.

[0104] For another example, the above-mentioned liquid level preset range may include a second height preset value S2 and / or a third height preset value (not shown), and the second height preset value S2 and / or the third height preset value may be set to be lower than the position height of the second port P2. Therefore, in some embodiments, by monitoring the liquid level H1 of the fluid 12 in the working tank liquid phase zone L1, the highest possible liquid level of the fluid 12 in the working tank liquid phase zone L1 can be controlled to be no higher than the second height preset value S2 and / or the third height preset value, and not higher than the position height of the second port P2. Therefore, in some embodiments, it can be ensured that the fluid 12 will not be transported to the buffer tank 20 through the second pipeline 320, thereby affecting the judgment of the control unit 34 and the actuation of the second valve member 321.

[0105] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the working tank 10 further includes a working tank pressure control assembly 14, which is located in the working tank body 11 and connected to the working tank gas phase zone V1. The working tank pressure control assembly 14 can be various devices with a pressure regulating function, such as a bellows. The working tank pressure control assembly 14 is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. The control unit 34 controls the working tank pressure control assembly 14 to adjust the pressure of the working tank gas phase zone V1. Therefore, in addition to the second valve component 321 and the second pipeline 320, the pressure of the working tank gas phase zone V1 can also be adjusted through the working tank pressure control assembly 14. Therefore, in some embodiments, for example, when the pressure of the second valve component 321 cannot be balanced in time or the operation is abnormal, the pressure of the working tank gas phase zone V1 can still be adjusted through the working tank pressure control assembly 14 to avoid affecting the cooling efficiency of the immersion cooling system 1 or even damaging the immersion cooling system 1.

[0106] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the buffer tank 20 further includes a buffer tank sensing component 23, which is used to sense the pressure of the buffer tank gas phase zone V2 and the liquid level H2 of the buffer tank liquid phase zone L2. The buffer tank sensing component 23 is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. In some embodiments, the control unit 34 is used to selectively actuate the second valve member 321 to connect the working tank gas phase zone V1 with the buffer tank gas phase zone V2 according to the pressure relationship between the working tank gas phase zone V1 and the buffer tank gas phase zone V2. In some embodiments, the control unit 34 is used to actuate the first pump 312 to transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2, or to transport the fluid 22 in the buffer tank liquid phase zone L2 to the working tank liquid phase zone L1 according to the relationship between the liquid level heights H1 and H2 between the working tank liquid phase zone L1 and the buffer tank liquid phase zone L2 (details will be described later). Thus, by monitoring the pressure of the gas phase region V2 of the buffer tank and / or the liquid level H2 of the liquid phase region L2 of the buffer tank, it can be determined whether the corresponding buffer tank 20 is suitable for immediate connection with the working tank 10 to perform the "maintenance mode" (or even the "backfill mode" and "circulation mode"; detailed later). In some embodiments, the immersion cooling system 1 may include a plurality of buffer tanks 20, 20' (see Fig. 9 , which will be described in detail later); therefore, by monitoring the pressure of the buffer tank gas phase zone V2 and / or the liquid level H2 of the buffer tank liquid phase zone L2 of the multiple buffer tanks 20, 20', the most suitable buffer tank among the multiple buffer tanks 20, 20' (for example, buffer tank 20') can be determined to perform "maintenance mode" (or even "backfill mode" and "circulation mode"), thereby reducing the lead-time originally required for each mode (for example, the time waiting for the fluid 22 in the buffer tank 20 to cool down).

[0107] Please continue to refer to Figures 1 to 3 In some embodiments, the buffer tank sensing assembly 23 includes a buffer tank pressure sensor 230, which is used to sense the pressure of the buffer tank gas phase region V2 and transmit the pressure of the buffer tank gas phase region V2 to the control unit 34. The buffer tank pressure sensor 230 can be various devices with pressure sensing functions (such as a pressure gauge) and is connected to the buffer tank body 21 to sense the pressure of the buffer tank gas phase region V2. The control unit 34 obtains the pressure of the buffer tank gas phase region V2 through the buffer tank pressure sensor 230. The control unit 34 further sends a specific control signal according to the pressure of the buffer tank gas phase region V2 to actuate various related components (the specific implementation can be referred to above and will not be described in detail here).

[0108] Please continue to refer to Figures 1 to 3In some embodiments, the buffer tank sensing assembly 23 includes a buffer tank liquid level sensor 231, which is used to sense the liquid level H2 of the fluid 22 in the buffer tank liquid phase area L2, and transmit the liquid level H2 of the fluid 22 back to the control unit 34. The buffer tank liquid level sensor 231 can be various devices with a liquid level sensing function (such as a liquid level sensor) and is connected to the buffer tank body 21 to sense, for example, the liquid level H2 of the fluid 22 in the buffer tank liquid phase area L2. The control unit 34 obtains the liquid level H2 of the fluid 22 through the buffer tank liquid level sensor 231. The control unit 34 further sends a specific control signal according to the liquid level H2 of the buffer tank liquid phase area L2 to actuate various related components (the specific implementation can be referred to above and will not be described in detail here).

[0109] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the buffer tank 20 further includes a buffer tank pressure control assembly 24, which is located in the buffer tank body 21 and communicates with the buffer tank gas phase region V2. The buffer tank pressure control assembly 24 can be various devices with a pressure adjustment function, such as a bellows. The buffer tank pressure control assembly 24 is communicatively connected to the control unit 34 to receive a control signal from the control unit 34. The control unit 34 controls the buffer tank pressure control assembly 24 to adjust the pressure of the buffer tank gas phase region V2.

[0110] The following further describes the implementation of the "maintenance mode".

[0111] Please refer to Figure 1 , Figure 2 and Figure 4 , Figure 4 For some embodiments, the immersion cooling system 1 is a flowchart of the maintenance mode. Figure 4 In the maintenance process S4, when the immersion cooling system 1 enters the "maintenance mode", in step S40, the control unit 34 receives the temperature of the liquid phase zone L1 of the working tank, and determines whether the temperature of the liquid phase zone L1 of the working tank is higher than the preset temperature value.

[0112] When the control unit 34 determines “No” in step S40 (ie, the temperature is not higher than the preset temperature value), the immersion cooling system 1 can enter the “open cover mode”, other modes, or continue the cooling operation without being affected.

[0113] When the control unit 34 determines in step S40 as "yes" (i.e., the temperature is higher than the preset temperature value), in step S41, the control unit 34 actuates the first pump 312 to selectively transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2 through the first pipeline 310, or to transport the fluid 22 in the buffer tank liquid phase zone L2 to the working tank liquid phase zone L1.

[0114] In some embodiments, the delivery process of the fluid 12 and / or the fluid 22 may be performed simultaneously or sequentially.

[0115] For example, the first control assembly 31 includes only a single pipeline for conveying the fluid 12 and / or the fluid 22, such as the first pipeline 310 (see Figure 1 ). The pipeline can sequentially transport the fluid 12 and / or the fluid 22, for example, first transport the fluid 12 to the buffer tank liquid phase region L2, or first transport the fluid 22 to the working tank liquid phase region L1. Based on this, by transporting the fluid 12 to the buffer tank 20 and timely transporting the fluid 22 with a lower temperature to the working tank 10, the fluid 12 in the working tank liquid phase region L1 can be effectively cooled, thereby reducing the waiting cooling time required for the working tank 10 (compared with the waiting cooling time required for the existing working tank), thereby reducing the cooling cost.

[0116] For another example, the first control assembly 31 may include a plurality of pipelines, such as a first pipeline 310 and a third pipeline 330 (see Figure 7 , which will be described in detail later). At least one of the multiple pipelines is used to transport the fluid 12 in the working tank liquid phase area L1 to the buffer tank liquid phase area L2; regardless of the order (i.e., simultaneously, first, or later), another at least one of the multiple pipelines is used to transport the fluid 22 in the buffer tank liquid phase area L2 to the working tank liquid phase area L1. Based on this, in some embodiments, through multiple pipelines for transporting the fluid 12 and / or the fluid 22, the fluid 12 with a higher temperature can be replaced with the fluid 12 with a lower temperature in a shorter time, thereby reducing the waiting cooling time required for the working tank 10 (compared with the waiting cooling time required for the existing working tank), thereby reducing the cooling cost.

[0117] At the same time or after step S41 , the control unit 34 obtains the pressure of the gas phase region V1 of the working tank. In step S42 , the control unit 34 determines whether the pressure of the gas phase region V1 of the working tank does not meet the preset pressure range.

[0118] When the control unit 34 determines “No” in step S42 (ie, the pressure meets the preset pressure range), the process returns to step S41 to continue delivering the fluid 12 and / or the fluid 22 .

[0119] When the control unit 34 determines "yes" (i.e., the pressure does not meet the preset pressure range) in step S42, in step S43, the control unit 34 actuates the second valve 321 to selectively connect the working tank gas phase zone V1 and the buffer tank gas phase zone V2 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is determined to be not in compliance with and lower than the preset pressure range, in step S43, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuation by the second pump (not shown), in step S43, the gas phase mixed fluid in the buffer tank gas phase zone V2 is transported to the working tank gas phase zone V1 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is determined to be not in compliance with and higher than the preset pressure range, in step S43, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuated by a second pump (not shown), in step S43 , the gas phase mixed fluid in the gas phase region V1 of the working tank is transported to the gas phase region V2 of the buffer tank through the second pipeline 320 .

[0120] In some embodiments, at the same time or after step S43, the control unit 34 continues to obtain the liquid level H1 of the liquid phase region L1 of the working tank. Then, the control unit 34 may selectively enter step S44 (e.g. Figure 4 as shown) or directly proceed to step S46 (i.e. omitting step S44).

[0121] If the process proceeds to step S44 , in step S44 , the control unit 34 determines whether the liquid level H1 of the liquid phase region L1 of the working tank is lower than the first preset height value S1 .

[0122] When the control unit 34 determines in step S44 that it is "yes" (i.e., the liquid level H1 is lower than the first preset height value S1), Figure 2 ), it will enter step S45, or enter step S41 (i.e., step S45 is omitted). In step S45, the control unit 34 will actuate the second valve member 321 to selectively disconnect the working tank gas phase region V1 and the buffer tank gas phase region V2; for example, the control unit 34 actuates the second valve member 321 to selectively close the second valve member 321, thereby preventing the gas-phase mixed fluid from flowing between the working tank gas phase region V1 and the buffer tank gas phase region V2. At the same time, the first pump 312 can be selectively not actuated to keep the first pipeline 310 connected; the first pump 312 can also be selectively actuated to disconnect the first pipeline 310. Then, return to step S41 to continue to transport the fluid 12 and / or the fluid 22.

[0123] When the control unit 34 determines in step S44 that the result is “No” (i.e., the liquid level H1 is higher than or equal to the first preset height value S1), Figure 1), the workflow then executes step S46; in step S46, the control unit 34 determines whether the liquid level H1 of the working tank liquid phase zone L1 is higher than the second height preset value S2; wherein the second height preset value S2 may be higher than or equal to the first height preset value S1.

[0124] When the control unit 34 determines as "No" in step S46 (i.e., the liquid level H1 is lower than or equal to the second height preset value S2), it returns to step S45 and step S41 to continue to transport the fluid 12 and / or fluid 22 until the liquid level H1 is higher than the second height preset value S2, and determines as "Yes" in step S46.

[0125] When the control unit 34 determines "yes" in step S46 (i.e., the liquid level H1 is higher than the second preset height value S2), the workflow then executes step S47; in step S47, the control unit 34 activates the first pump 312 to selectively disconnect the working tank liquid phase area L1 and the buffer tank liquid phase area L2; in no particular order, in step S48, the control unit 34 activates the second valve 321 to selectively disconnect the working tank gas phase area V1 and the buffer tank gas phase area V2. At this time, the working tank 10 and the buffer tank 20 are not connected to each other, and the working tank 10 can enter the "open cover mode", other modes, or continue the cooling operation of the cooling element 15 without being affected.

[0126] In some embodiments where step S44 is omitted, the control unit 34 only determines whether the liquid level H1 is higher than the second preset height value S2 in step S46. When the liquid level H1 is slightly higher than or equal to the second preset height value S2, step S46 can be determined to be completed. In this embodiment, the control unit 34 may frequently determine that the liquid level H1 is insufficient and frequently enter the "maintenance mode" or the "backfill mode" described later. In other words, the height difference that the control unit 34 can tolerate in its judgment is relatively small.

[0127] In contrast, in some embodiments including step S44, the control unit 34 must first determine whether the liquid level H1 is lower than the first preset height value S1, and directly raise the liquid level H1 from the first preset height value S1 to at least the second preset height value S2. In other words, when the second preset height value S2 is much higher than the first preset height value S1, the height difference (the difference between the second preset height value S2 and the first preset height value S1) that can be tolerated by the control unit 34 is relatively large. Based on this, in this embodiment, by appropriately setting the first preset height value S1 and the second preset height value S2, the control unit 34 can avoid frequently determining that the liquid level H1 is insufficient, and can extend the working time between this and the next "maintenance mode" or the "backfill mode" described later.

[0128] Based on this, in some embodiments, before entering the "opening mode" or other modes, by quickly transferring the higher temperature fluid 12 in the working tank 10 to the buffer tank 20, or assisted by transferring the lower temperature fluid 22 in the buffer tank 20 to the working tank 10, the waiting cooling time required for the working tank 10 can be greatly reduced (compared with the waiting cooling time required for the existing working tank), thereby reducing the cooling cost.

[0129] The implementation of the "backfill mode" is further described below.

[0130] Please refer to Figure 1 , Figure 2 and Figure 5 , Figure 5 For some embodiments, the immersion cooling system 1 is a flowchart of the backfill mode. The backfill mode can be as follows: Figure 4 Execute in "maintenance mode" of Figure 4 However, in some embodiments, the control unit 34 may selectively actuate the second valve 321 to at least disconnect the working tank gas phase region V1 and the buffer tank gas phase region V2 before entering the "backfill mode". Or in some embodiments, the "backfill mode" is executed separately from the "maintenance mode", which is not limited.

[0131] exist Figure 5 In the backfill process S5, when the immersion cooling system 1 enters the "backfill mode", in step S50, the control unit 34 obtains the liquid level H1 of the liquid phase zone L1 of the working tank, and determines whether the liquid level H1 of the liquid phase zone L1 of the working tank is lower than the first height preset value S1.

[0132] When the control unit 34 determines "No" in step S50 (ie, the liquid level H1 is higher than or equal to the first preset height value S1), Figure 1 ), the immersion cooling system 1 can enter other modes (such as "open cover mode"), or continue the cooling operation of the cooling element 15 without being affected.

[0133] When the control unit 34 determines "yes" in step S50 (ie, the liquid level H1 is lower than the first preset height value S1), Figure 2 ), the workflow then executes step S51; in step S51, the control unit 34 activates the first pump 312 to connect the first pipeline 310, and selectively delivers the fluid 22 in the buffer tank liquid phase region L2 to the working tank liquid phase region L1 through the first pipeline 310. At the same time (i.e., before entering step S52), the control unit 34 has at least activated the second valve 321 to prevent the second pipeline 320 from connecting the working tank gas phase region V1 and the buffer tank gas phase region V2.

[0134] At the same time or after step S51 , the control unit 34 obtains the pressure of the gas phase region V1 of the working tank. In step S52 , the control unit 34 determines whether the pressure of the gas phase region V1 of the working tank does not meet the preset pressure range.

[0135] When the control unit 34 determines “No” in step S52 (ie, the pressure meets the preset pressure range), the process returns to step S51 to continue conveying the fluid 22 to the liquid phase region L1 of the working tank.

[0136] When the control unit 34 determines "yes" in step S52 (i.e., the pressure does not meet the preset pressure range), in step S53, the control unit 34 actuates the second valve 321 to selectively connect the working tank gas phase zone V1 and the buffer tank gas phase zone V2 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is determined to be not in compliance with and higher than the preset pressure range, in step S53, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuation by the second pump (not shown), in step S53, the gas phase mixed fluid in the working tank gas phase zone V1 is transported to the buffer tank gas phase zone V2 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is determined to be not in compliance with and lower than the preset pressure range, the workflow then executes step S53; in step S53, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuated by a second pump (not shown), in step S53 , the gas phase mixed fluid in the gas phase region V2 of the buffer tank is transported to the gas phase region V1 of the working tank through the second pipeline 320 .

[0137] In some embodiments, at the same time or after step S53, the control unit 34 continues to obtain the liquid level H1 of the working tank liquid phase region L1. In step S54, the control unit 34 determines whether the liquid level H1 of the working tank liquid phase region L1 is higher than the second preset height value S2 (higher than or equal to the first preset height value S1).

[0138] When the control unit 34 determines "No" in step S54 (i.e., the liquid level H1 is lower than or equal to the second preset height value S2), the process proceeds to step S55, or proceeds to step S51 (omit step S55). In step S55, the control unit 34 actuates the second valve 321 to selectively disconnect the working tank gas phase region V1 from the buffer tank gas phase region V2, and returns to step S51 to continue to transport the fluid 22 to the working tank liquid phase region L1.

[0139] When the control unit 34 determines in step S54 that it is "yes" (i.e., the liquid level H1 is higher than the second preset height value S2, such as Figure 1), the workflow then executes step S56; in step S56, the control unit 34 actuates the first pump 312 to selectively disconnect the working tank liquid phase area L1 and the buffer tank liquid phase area L2. In some embodiments, the second height preset value S2 is also set to a position height lower than the second interface P2 to ensure that the fluid 12 will not be delivered to the second pipeline 320. In no particular order, in step S57, the control unit 34 actuates the second valve member 321 to selectively disconnect the working tank gas phase area V1 and the buffer tank gas phase area V2. At this time, the working tank 10 and the buffer tank 20 are not connected to each other, completing the "backfill mode". At this time, the working tank 10 may enter other modes (such as the "open cover mode"), or continue the cooling operation of the cooling element 15 without being affected.

[0140] Please refer to Figure 1 and Figure 6 , Figure 6 1 is a flowchart of the operation of the immersion cooling system 1 in the circulation mode in some embodiments. The "circulation mode" can be as follows: Figure 4 Execute in "maintenance mode" of Figure 4 However, in some embodiments, the control unit 34 may selectively actuate the second valve 321 to at least disconnect the working tank gas phase region V1 and the buffer tank gas phase region V2 before entering the "circulation mode". Alternatively, in some embodiments, the "circulation mode" may also be executed independently of the "maintenance mode", which is not limited.

[0141] exist Figure 6 In the circulation process S6, when the immersion cooling system 1 enters the "circulation mode", in step S60, the control unit 34 obtains the liquid level H1 of the working tank liquid phase zone L1, and determines whether the liquid level H1 of the working tank liquid phase zone L1 is higher than the third preset height value (not shown); wherein the third preset height value is higher than or equal to the second preset height value S2, and the second preset height value S2 is higher than or equal to the first preset height value S1. In some embodiments, the third preset height value is also set to be lower than the position height of the second interface P2 to monitor the liquid level H1 of the working tank liquid phase zone L1 to ensure that the fluid 12 is not delivered to the second pipeline 320.

[0142] When the control unit 34 determines “No” in step S60 (ie, the liquid level H1 is lower than or equal to the third preset height value), the immersion cooling system 1 can enter other modes (eg, “open cover mode”) or continue cooling the cooling element 15 without being affected.

[0143] When the control unit 34 determines "yes" in step S60 (i.e., the liquid level H1 is higher than the third preset height value), the workflow then executes step S61; in step S61, the control unit 34 activates the first pump 312 to connect the first pipeline 310, and selectively transports the fluid 12 in the working tank liquid phase region L1 to the buffer tank liquid phase region L2 through the first pipeline 310. At the same time (i.e., before entering step S62), the control unit 34 has at least activated the second valve 321 to prevent the second pipeline 320 from connecting the working tank gas phase region V1 and the buffer tank gas phase region V2.

[0144] In some embodiments, at the same time or after step S61, the control unit 34 continues to obtain the pressure of the gas phase region V1 of the working tank. In step S62, the control unit 34 determines whether the pressure of the gas phase region V1 of the working tank does not meet the preset pressure range.

[0145] When the control unit 34 determines “No” in step S62 (ie, the pressure meets the preset pressure range), the process returns to step S61 to continue conveying the fluid 12 to the liquid phase region L2 of the buffer tank.

[0146] When the control unit 34 determines "yes" (i.e., the pressure does not meet the preset pressure range) in step S62, the workflow then executes step S63; in step S63, the control unit 34 actuates the second valve 321 to selectively connect the working tank gas phase zone V1 and the buffer tank gas phase zone V2 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is judged to be not in compliance with and lower than the preset pressure range, in step S63, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuation by the second pump (not shown), in step S63, the gas phase mixed fluid in the buffer tank gas phase zone V2 is transported to the working tank gas phase zone V1 through the second pipeline 320. In some embodiments, when the pressure of the working tank gas phase zone V1 is judged to be not in compliance with and higher than the preset pressure range, in step S63, the control unit 34 actuates the second valve 321. Due to the pressure difference or actuated by a second pump (not shown), in step S63 , the gas phase mixed fluid in the gas phase region V1 of the working tank is transported to the gas phase region V2 of the buffer tank through the second pipeline 320 .

[0147] In some embodiments, at the same time or after step S63, the control unit 34 continues to obtain the liquid level H1 of the working tank liquid phase region L1. In step S64, the control unit 34 determines whether the liquid level H1 of the working tank liquid phase region L1 is lower than the second preset height value S2.

[0148] When the control unit 34 determines in step S64 that the result is “No” (i.e., the liquid level H1 is higher than or equal to the second preset height value S2), Figure 1), then the process proceeds to step S65, or proceeds to step S61 (i.e., omitting step S65). In step S65, the control unit 34 actuates the second valve member 321 to selectively disconnect the working tank gas phase region V1 from the buffer tank gas phase region V2, and returns to step S61 to continue conveying the fluid 12 to the buffer tank liquid phase region L2.

[0149] When the control unit 34 determines "yes" in step S64 (i.e., the liquid level H1 is lower than the second height preset value S2), the workflow then executes step S66; in step S66, the control unit 34 actuates the first pump 312 to selectively disconnect the working tank liquid phase area L1 and the buffer tank liquid phase area L2; in no particular order, in step S67, the control unit 34 actuates the second valve 321 to selectively disconnect the working tank gas phase area V1 and the buffer tank gas phase area V2. At this time, the working tank 10 and the buffer tank 20 are not connected to each other, completing the "circulation mode". At this time, the working tank 10 can enter other modes (such as "open cover mode"), or continue the cooling operation of the cooling element 15 without being affected.

[0150] Please also refer to Figure 3 , Figure 7 and Figure 8 , Figure 7 A schematic diagram of the structure of the first working state of the immersion cooling system 1 in some embodiments; Figure 8 For Figure 7 The immersion cooling system 1 is a schematic structural diagram of its second working state. Figure 7 and Figure 8 The immersion cooling system 1 shown is Figure 1 and Figure 2 The immersion cooling system 1 shown is substantially the same, with the main difference being that: Figure 7 and Figure 8 In addition to the first control component 31 and the second control component 32, the communication control component 30 also includes a third control component 33. Figure 7 and Figure 8 The first control component 31 may also include a first pipeline 310, a first valve component 311, a first pump 312 and a first filter component 313; the second control component 32 may also include a second pipeline 320, a second valve component 321 and a dehumidification unit 322; the specific implementation forms of the above-mentioned components can be referred to above and will not be described in detail here.

[0151] exist Figure 7 and Figure 8 The third control component 33 may include a third pipeline 330 , a third valve member 331 and a third pump 332 .

[0152] Please continue to refer to Figure 7 and Figure 8In some embodiments, one end of the third pipeline 330 can be directly connected to the working tank liquid phase area L1, and the other end of the third pipeline 330 can be directly connected to the buffer tank liquid phase area L2. Figure 7 , one end of the third pipeline 330 is connected to the top of the working tank liquid phase area L1 through the third interface P3, and the other end of the third pipeline 330 is connected to the buffer tank liquid phase area L2 (for example, the top of the buffer tank liquid phase area L2); one end of the first pipeline 310 is connected to the bottom of the working tank liquid phase area L1 through the first interface P1, and the other end of the first pipeline 310 is connected to the buffer tank liquid phase area L2 (for example, the bottom of the buffer tank liquid phase area L2). In some embodiments, the position height of the third interface P3 is higher than the position height of the first interface P1, and the position height of the second interface P2 is higher than the position height of the third interface P3. Based on this, Figure 7 , the fluid 12 at the top of the working tank liquid phase area L1 and the fluid 22 in the buffer tank liquid phase area L2 can be directly transported between the working tank liquid phase area L1 and the buffer tank liquid phase area L2 through the third interface P3. The fluid 12 at the bottom of the working tank liquid phase area L1 and the fluid 22 in the buffer tank liquid phase area L2 can be directly transported between the working tank liquid phase area L1 and the buffer tank liquid phase area L2 through the first interface P1.

[0153] Due to the physical and chemical properties of the working fluid, the fluid 12 with a higher temperature will flow to the top of the working tank liquid phase area L1; relatively, the fluid 12 with a lower temperature will gather at the bottom of the working tank liquid phase area L1. Therefore, through the third pipeline 330 and the third interface P3, the fluid 12 with a higher temperature can be more effectively and quickly transported to the buffer tank liquid phase area L2, and the fluid 12 with a lower temperature can be retained in the working tank liquid phase area L1. Therefore, in some embodiments, through the third pipeline 330 and the third interface P3, the fluid 12 in the working tank liquid phase area L1 can be more effectively and quickly cooled, greatly shortening the cooling time of the fluid 12.

[0154] In addition, Figure 7 and Figure 8 , through the first pipeline 310 and the first port P1, the lower temperature fluid 22 in the buffer tank liquid phase area L2 can be more effectively and quickly transported to the bottom of the working tank liquid phase area L1, and the fluid 22 is prevented from directly contacting the top of the working tank liquid phase area L1. Therefore, in some embodiments, the total amount of the lower temperature fluid 12 can be more effectively increased through the first pipeline 310 and the first port P1.

[0155] Please continue to refer to Figure 7 and Figure 8In some embodiments, the first pipeline 310 and the third pipeline 330 can perform the aforementioned exchange of the bottom (lower temperature) and / or top (higher temperature) fluid 12 and fluid 22 simultaneously or sequentially (i.e., the order is distinguished, but there is no limitation on which comes first and which comes later) to more quickly achieve the effect of replacing the higher temperature fluid 12 with the lower temperature fluid 12.

[0156] besides, Figure 3 , Figure 7 and Figure 8 The third control component 33 can basically refer to Figures 1 to 3 The first control component 31 is configured, so its specific implementation can refer to the above.

[0157] That is, please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments, the control unit 34 can be used in a maintenance mode and when the temperature of the working tank liquid phase zone L1 is higher than the preset temperature value, the first pump 312 is actuated to transport the fluid 22 in the buffer tank liquid phase zone L2 to the working tank liquid phase zone L1, and the third pump 332 is actuated to transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2.

[0158] Please continue to refer to Figure 3 , Figure 7 and Figure 8 In some embodiments, the working tank sensing assembly 13 is further used to sense the liquid level H1 of the working tank liquid phase region L1; the control unit 34 is further used to actuate the second valve member 321 to disconnect the working tank 10 and the buffer tank 20 and not actuate the first pump 312 when the liquid level H1 of the working tank liquid phase region L1 is lower than the first height preset value S1 in the maintenance mode. The specific implementation of the first height preset value S1 can be referred to above and will not be described in detail here.

[0159] Please continue to refer to Figure 3 , Figure 7 and Figure 8 In some embodiments, the control unit 34 actuates the second valve 321 to connect the working tank gas phase zone V1 and the buffer tank gas phase zone V2 in the backfill mode, and actuates the first pump 312 to transport the fluid 22 in the buffer tank liquid phase zone L2 to the working tank liquid phase zone L1, and actuates the third pump 332 to transport the fluid 12 in the working tank liquid phase zone L1 to the buffer tank liquid phase zone L2, until the liquid level H1 of the working tank liquid phase zone L1 is higher than, for example, the aforementioned second height preset value S2.

[0160] Please continue to refer to Figure 3 , Figure 7 and Figure 8In some embodiments, the third control assembly 33 further includes a third filter 333, which is located in the third pipeline 330 and is disposed between the working tank 10 and the buffer tank 20. The third filter 333 can be located between the working tank 10 and the third pump 332 (see Figure 7 ), or between the third pump 332 and the buffer tank 20. The third filter element 333 is similar to the first filter element 313, so the specific implementation of the third filter element 333 can refer to the implementation of the first filter element 313, which will not be described in detail.

[0161] In some embodiments, the immersion cooling system 1 may include not only one working tank 10, but also multiple working tanks (eg Fig.10 Alternatively, in some embodiments, the immersion cooling system 1 may include not only one buffer tank 20, but also a plurality of buffer tanks (eg Fig. 9 Therefore, in some embodiments, the configuration of the working tank 10 and the buffer tank 20 can be adjusted according to different cooling requirements to achieve corresponding cooling performance, thereby reducing the waiting cooling time required for the working tank 10 (compared with the waiting cooling time required for the existing working tank), thereby reducing the cooling cost.

[0162] For example, see Fig. 9 , Fig. 9 FIG. 1 is a schematic diagram of the structure of an immersion cooling system 1 in some embodiments. Fig. 9The immersion cooling system 1 may include a plurality of buffer tanks 20, 20'. Through the corresponding first pipeline 310 (or 310') (located at the first interface P1 (or P1') corresponding to the buffer tank 20 (or 20')), the fluid 12 in the working tank liquid phase zone L1 is selectively transported to at least one of the buffer tank liquid phase zones L2, L2', or the fluid 22 (or 22') in at least one of the buffer tank liquid phase zones L2, L2' is transported to the working tank liquid phase zone L1. The buffer tank gas phase zone V2, V2' of each buffer tank 20, 20' is selectively connected or disconnected with the working tank gas phase zone V1 of the working tank 10 through the corresponding second pipeline 320, 320' (respectively located at the second interface P2, P2'). The specific implementation forms of the above-mentioned buffer tank 20' (which may include a buffer tank body 21', a fluid 22', a buffer tank sensing component 23', a buffer tank pressure control component 24' and a dehumidification component 25', wherein the buffer tank sensing component 23' may include a buffer tank pressure sensor 230' and a buffer tank liquid level sensor 231', and may have a buffer tank gas phase area V2' and a buffer tank liquid phase area L2') and a connecting control component 30' (which may include a first control component 31' and a second control component 32', wherein the first control component 31' may include a first pipeline 310', a first valve component 311', a first pump 312' and a first filter component 313', and the second control component 32' may include a second pipeline 320', a second valve component 321' and a dehumidification part 322') can be referred to as above and will not be described in detail here. In addition, it should be noted that in some embodiments, the immersion cooling system 1 may also include other components mentioned above in this article, but whether or not they are shown in the figure Fig. 9 components, not just Fig. 9 The illustrated implementation aspects.

[0163] For example, the first pipeline 310, 310' can be connected to a transfer pipeline to selectively connect to the working tank 10 through the transfer pipeline. For example, the transfer pipeline is a T-shaped connecting pipe with three interfaces, one of which is connected to the first pipeline 310, another interface is connected to the first pipeline 310', and the remaining interface is connected to the working tank liquid phase L1 of the working tank 10, thereby simplifying the overall structure of the working tank 10. Therefore, in some embodiments, the fluid 12 and / or the fluid 22, 22' of the first pipeline 310, 310' can be transported after being concentrated through the transfer pipeline, which can not only simplify the cooling process, but also make the flow rate of the fluid 12 and / or the fluid 22, 22' more stable.

[0164] In some embodiments, the control unit 34 is connected to the plurality of buffer tanks 20, 20' in communication, so as to actuate the first control components 31, 31' and / or the second control components 32, 32' according to the current status (such as pressure and / or liquid level) of each buffer tank 20, 20', so as to selectively connect the working tank 10 with at least one of the plurality of buffer tanks 20, 20'. Fig. 9 The control unit 34 can selectively connect the buffer tank (e.g., Fig. 9 The buffer tank liquid phase area L2' of the buffer tank 20') and the working tank liquid phase area L1 of the working tank 10 are connected to allow the fluid 22' (and / or the fluid 12) to be transported to the first pipeline 310' along the third direction D3' (third direction D3); at the same time, the buffer tank (e.g. Fig. 9 The buffer tank gas phase zone V2' of the buffer tank 20') and the working tank gas phase zone V1 of the working tank 10 are connected to allow the gas phase mixed fluid to be transported to the second pipeline 320' along the fourth direction D4', D4. As a result, the working tank 10 can be instantly connected to at least one of the most suitable buffer tanks 20, 20' under different reference standards (for example, the instantaneous state of each buffer tank 20, 20'). Therefore, in some embodiments, it can be continuously ensured that the working tank 10 contains a low-temperature fluid 12, which not only provides good cooling performance, but also reduces the waiting cooling time required for the working tank 10 (compared with the waiting cooling time required for the existing working tank).

[0165] For another example, please refer to Fig.10 , Fig.10 FIG. 1 is a schematic diagram of the structure of an immersion cooling system 1 in some embodiments. Fig.10The immersion cooling system 1 may include a plurality of working tanks 10, 10'. Through the corresponding first pipeline 310 (or 310'), the fluid 12 (or 12') of at least one of the working tank liquid phase areas L1, L1' is selectively transported to the buffer tank liquid phase area L2, or the fluid 22 of the buffer tank liquid phase area L2 is transported to at least one of the working tank liquid phase areas L1, L1'. The buffer tank gas phase area V2 is selectively connected or disconnected with the corresponding working tank gas phase area V1, V1' through the corresponding second pipeline 320, 320'. The specific implementation forms of the above-mentioned working tank 10' (which may include a working tank body 11', a fluid 12', a working tank sensing component 13', a working tank pressure control component 14' and a to-be-cooled element 15', wherein the working tank sensing component 13' may include a working tank temperature sensor 130', a working tank pressure sensor 131' and a working tank liquid level sensor 132', and may have a working tank gas phase area V1' (including an air sub-area V11' and a steam sub-area V12') and a working tank liquid phase area L1') and a connecting control component 30' (which may include a first control component 31' and a second control component 32', wherein the first control component 31' may include a first pipeline 310', a first valve component 311', a first pump 312' and a first filter component 313', and the second control component 32' may include a second pipeline 320', a second valve component 321' and a dehumidification part 322') can be referred to the above and will not be described in detail here. In addition, it should be noted that in some embodiments, the immersion cooling system 1 may also include other components mentioned above but not shown in the figure. Fig.10 components, not just Fig.10 The illustrated implementation aspects.

[0166] For example, the first pipeline 310, 310' can be connected to a transfer pipeline to selectively connect to the buffer tank 20 through the transfer pipeline. For example, the transfer pipeline is a T-shaped connecting pipe with three interfaces, one of which is connected to the first pipeline 310, another is connected to the first pipeline 310', and the remaining one is connected to the buffer tank liquid phase area L2 of the buffer tank 20. Therefore, in some embodiments, the fluid 12, 12' and / or the fluid 22 of the first pipeline 310, 310' can be transported after being concentrated through the transfer pipeline, which can not only simplify the cooling process, but also make the flow of the fluid 12, 12' and / or the fluid 22 more stable.

[0167] In addition, in some embodiments, the control unit 34 is communicatively connected to the plurality of working tanks 10, 10' to actuate the first control components 31, 31' and / or the second control components 32, 32' according to the current status (e.g., pressure and / or liquid level) of each working tank 10, 10' to selectively connect at least one of the plurality of working tanks 10, 10' and the buffer tank 20. Fig.10The control unit 34 can selectively connect the working tank 10, 10' with the one with the higher liquid level (e.g. Fig.10 The working tank liquid phase area L1' of the working tank 10') and the buffer tank liquid phase area L2 of the buffer tank 20 are connected to allow the fluid 12' (and / or the fluid 22) to be transported to the first pipeline 310' along the third direction D3 (third direction D3'); at the same time, the pressure of the buffer tank 20 (e.g. Fig.10 The working tank gas phase zone V1' of the working tank 10') and the buffer tank gas phase zone V2 of the buffer tank 20 are connected to make the gas phase mixed fluid be transported to the second pipeline 320' along the fourth direction D4, D4'. Thus, at least one working tank 10 (or 10') that needs to be cooled or maintained among the multiple working tanks 10, 10' can be connected to the buffer tank 20 in real time according to different reference standards (for example, the real-time status of each working tank 10, 10'). Therefore, in some embodiments, it can be continuously ensured that the multiple working tanks 10, 10' contain low-temperature fluids 12, 12', which can not only provide a good overall cooling performance of the multiple working tanks 10, 10', but also reduce the overall cooling time required for the existing working tanks.

[0168] In summary, in some embodiments, one end of a plurality of pipelines is respectively connected to the working tank, and the other ends of the plurality of pipelines are respectively connected to the buffer tank, and a part of the pipelines can be connected to the liquid-phase working fluid in the working tank and / or the buffer tank, and another part of the pipelines can be connected to the gas-phase mixed fluid in the working tank and / or the buffer tank. Therefore, the fluid in the working tank can be selectively transported to the buffer tank, and a cooling effect significantly better than that of the existing system can be achieved in a shorter time. Even in some embodiments, the liquid-phase working fluid with a lower temperature in the buffer tank can be transported to the working tank, and a cooling effect significantly better than that of the existing system can be achieved more quickly and effectively. Based on this, in some embodiments, the overall cooling efficiency can be significantly improved, the dissipation of a large amount of gas-phase working fluid can be reduced, and the longer cooling waiting time required in the past can be avoided, thereby reducing the cooling cost.

[0169] Although the present invention is disclosed as above by the aforementioned embodiments, it is not intended to limit the present invention. Anyone familiar with similar techniques may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be based on the definition of the claims attached to this specification.
