[0046] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0048] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0050] Before further describing the embodiments of the present application in detail, the nouns and terms involved in the embodiments of the present application are explained. The nouns and terms involved in the embodiments of the present application are subject to the following interpretations.

[0051] 1) Liquid cooling is a cooling technology that uses liquid as a cooling medium, removing heat from the heat source and dissipating it to the surrounding environment through the flow of liquid. It operates based on the principles of heat conduction and convection. Through contact between the liquid and the heat-generating component, it absorbs heat, circulates to a radiator or heat exchanger, and releases it to the surrounding environment. In practical applications, liquid cooling systems can be applied to data center servers, high-performance computers, electric vehicles, medical equipment, industrial equipment, and personal computers.

[0052] 2) Cooling fluid refers to the substance that circulates in a refrigeration or cooling system, absorbing and releasing heat to achieve the purpose of cooling. It can be liquid, gaseous, or a substance that undergoes phase change during the process of absorbing and releasing heat.

[0053] Common cooling media include the following categories:

[0054] 1. Water-based coolants: Pure water, with its high specific heat capacity and good thermal conductivity, is commonly used in industrial cooling systems. A mixture of water and antifreeze is used in low-temperature environments, such as automotive cooling systems. Formulated solutions, containing corrosion inhibitors and biocides, are used to prevent corrosion and microbial growth.

[0055] 2. Organic liquid coolants: Mineral oil, with its chemically stable properties, is commonly used for transformer cooling. Silicone oil, with its excellent thermal stability and chemical inertness, is suitable for cooling electronic equipment. Vegetable oils, such as natural esters, offer environmental advantages and can be used for battery cooling.

[0056] 3. Synthetic cooling fluids: Fluorinated fluids, such as electronic fluorinated fluid (Novec-7200), offer high insulation and low toxicity, making them suitable for immersion cooling of electronic equipment. Hydrofluoroolefins, with their low global warming potential (GWP) and good chemical stability, are suitable for liquid cooling systems in data centers and semiconductor manufacturing.

[0057] 4. Cryogenic working fluids: Liquid nitrogen, liquid oxygen, and liquid argon are used for air separation and cryogenic refrigeration. Liquid hydrogen and liquid helium are used for ultra-low temperature refrigeration and scientific research.

[0058] 5. Two-phase cooling fluid: This type of fluid will vaporize when absorbing heat and remove heat through the latent heat of vaporization. It is often used to cool high-power equipment such as lasers and hypersonic aircraft.

[0059] The selection of cooling fluid should be based on the needs of the specific application, taking into account its thermal performance, chemical stability, environmental impact and compatibility with the system.

[0060] 3) A liquid level sensor (static pressure level gauge / level transmitter / level sensor / water level sensor) is a pressure sensor that measures liquid level. A static pressure submersible level transmitter (level gauge) works based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensor or a ceramic capacitor pressure sensor to convert the static pressure into an electrical signal. After temperature compensation and linear correction, it is converted into a standard electrical signal (typically 4-20mA / 1-5VDC). It is suitable for level measurement of various media in systems and industries such as petrochemicals, metallurgy, power generation, pharmaceuticals, water supply and drainage, and environmental protection.

[0061] 4) The main functions of the electric valve include on-off control and regulating control. The electric valve controls the opening and closing of the valve through the electric actuator, thereby realizing the on-off control of the medium in the pipeline.

[0062] 5) The main function of a check valve is to prevent the medium from flowing back. It allows the medium to flow in one direction in the pipeline. When the medium flows in from the inlet end, the valve opens; when the medium tries to flow back, the valve closes, thus preventing the medium from flowing back.

[0063] The embodiment of the present application provides a liquid replenishing device for a liquid cooling system and a liquid replenishing control method thereof, which can conveniently replenish liquid to the liquid cooling system and improve the convenience of liquid replenishment.

[0064] The following describes the liquid replenishing device of the liquid cooling system provided in the embodiment of the present application. Figure 1 , Figure 1This is an optional structural schematic diagram of a liquid replenishing device for a liquid cooling system provided in an embodiment of the present application. The liquid replenishing device 100 for a liquid cooling system includes a control module 101, a first box 102, a second box 103, a water pump module 104, a liquid level sensor 105 and a switch module 106; the liquid level sensor 105 is used to detect the liquid level of the cooling medium in the first box 102; the control module 101 is connected to the liquid level sensor 105 and the switch module 106, and is used to control the conduction state of the switch module 106 according to the liquid level to control the conduction of the first channel, the second channel or the third channel; wherein, the first channel includes the first box 102, the water pump module 104 and the liquid cooling system 110, the second channel includes the second box 103, the water pump module 104 and the liquid cooling system 110, and the third channel includes the second box 103, the water pump module 104 and the first box 102.

[0065] In this embodiment of the present application, the coolant is liquid, and the refill device 100 is used to replenish the coolant in the liquid cooling system 110. The first housing 102 and the second housing 103 are used to contain the coolant. The coolant is a liquid coolant that flows through the liquid cooling system 110 and then cools the external device. The external device may include, but is not limited to, data center servers, high-performance computers, electric vehicles, medical equipment, industrial equipment, or personal computers.

[0066] In actual implementation, see Figure 1 , the liquid level sensor 105 is arranged in the first tank 102, and is used to detect the liquid level of the cooling medium in the first tank 102. The control module 101 can receive the liquid level of the cooling medium in the first tank 102 detected by the liquid level sensor 105, and based on the liquid level, control the conduction state of the switch module 106, thereby controlling the conduction of the first channel, the second channel or the third channel. Here, the first channel includes the first tank 102, the water pump module 104 and the liquid cooling system 110. Among them, the water pump module 104 may include one or more refill pumps for transmitting the cooling medium, and the first channel is used to transmit the cooling medium in the first tank 102 to the liquid cooling system 110 through the water pump module 104 to replenish the liquid cooling system 110. The second channel includes the second tank 103, the water pump module 104 and the liquid cooling system 110. The second channel is used to transfer the coolant in the second tank 103 to the liquid cooling system 110 via the water pump module 104, thereby replenishing the liquid cooling system 110. The third channel includes the second tank 103, the water pump module 104, and the first tank 102. The third channel is used to transfer the coolant in the second tank 103 to the first tank 102 via the water pump module 104, thereby replenishing the first tank 102. This ensures that there is sufficient coolant in the first tank 102 to replenish the liquid cooling system 110.

[0067] In one embodiment, the control module 101 can obtain the detected liquid level from the liquid level sensor 105 in response to the arrival of the time period. Here, the time period is preset, for example, it can be 1s, and the control module 101 obtains the liquid level of the cooling medium in the first box 101 from the liquid level sensor 105 every second to replenish the liquid cooling system based on the liquid level. Those skilled in the art can set appropriate values ​​according to actual needs to be able to replenish the liquid replenishment system in a timely manner while avoiding excessive power consumption. In some embodiments, the control module 101 can also obtain the detected liquid level from the liquid level sensor 105 in real time. Through the detection of the liquid level sensor and the corresponding replenishment control, the cooling medium can be replenished in a timely manner.

[0068] In some embodiments, the control module 101 obtains the liquid level of the cooling medium in the first box 102 detected by the liquid level sensor 105; when the liquid level is greater than the liquid level threshold, the conduction state of the switch module 106 is controlled to control the conduction of the first channel; when the liquid level is less than or equal to the liquid level threshold, the conduction state of the switch module 106 is controlled to control the conduction of the second channel and / or the conduction of the third channel.

[0069] In actual implementation, after the control module 101 obtains the liquid level of the coolant in the first tank 102 detected by the liquid level sensor 105, it compares the liquid level of the coolant in the first tank 102 with the liquid level threshold. When the liquid level is greater than the liquid level threshold, the switch module 106 is controlled to control the conduction state to control the conduction of the first channel. When the liquid level is less than or equal to the liquid level threshold, the switch module 106 is controlled to control the conduction state to control the conduction of the second channel and / or the conduction of the third channel. Here, those skilled in the art can set an appropriate value for the liquid level threshold based on the specific needs of the liquid cooling system 110, so that when the liquid level of the coolant in the first tank 102 is greater than the liquid level threshold, there is sufficient coolant to meet the liquid replenishment demand of the liquid cooling system 110, so that the liquid cooling system 110 can be replenished directly through the first tank 102. When the liquid level is less than or equal to the liquid level threshold, the second channel is opened to allow the coolant in the second box 103 to replenish the liquid cooling system 110, or the third channel is opened to replenish the first box 102 through the second box 103 until the liquid level of the first box 102 is greater than the liquid level threshold, and then the liquid cooling system 110 is replenished through the first box 102.

[0070] In one embodiment, the control module 101 may further control the second channel to be conductive first. After the second channel is conductive for a first duration, the switch module 106 is controlled to be conductive to control the third channel to be conductive. Here, the first duration is the duration required to meet the liquid replenishment needs of the liquid cooling system 110. After the liquid cooling system is replenished with the coolant in the second tank 103, the first tank 102 is replenished with liquid through the second tank 103, so that the first tank 102 can directly replenish the liquid cooling system 110.

[0071] In actual implementation, the control module 101 may also be connected to the liquid cooling system 110. When receiving a refill instruction from the liquid cooling system 110, the control module 101 obtains the liquid level of the first tank 102. If the liquid level is greater than a liquid level threshold, the control module 101 controls the first channel to be conductive, and directly refills the liquid cooling system 110 with liquid through the first tank 102. If the liquid level is less than or equal to the liquid level threshold, the control module 101 controls the second channel to be conductive, and refills the liquid cooling system 110 with liquid through the second tank 103. If no refill instruction from the liquid cooling system 110 is received, if the liquid level of the coolant in the first tank 102 detected by the liquid level sensor 105 is less than or equal to the liquid level threshold, the control module 101 controls the third channel to be conductive, and causes the second tank 103 to refill the first tank 102 with liquid through the third channel.

[0072] In the embodiment of the present application, by automatically monitoring the liquid level of the first tank and controlling the conduction of the three channels based on the liquid level, on the one hand, the redundant second channel can be used to avoid the inability to replenish liquid when the cooling medium in the first tank is insufficient, thereby improving the timeliness of liquid replenishment. On the other hand, the cooling medium of the first tank can be replenished through the third channel, thereby maximizing the utilization of the liquid replenishment pump. By replenishing liquid through the three channels, the convenience of liquid replenishment is improved.

[0073] In some embodiments, see Figure 2 , Figure 2 1 is a schematic diagram of an optional structure of a liquid replenishing device for a liquid cooling system provided in an embodiment of the present application. The liquid outlet 1021 of the first housing 102 and the liquid outlet 1031 of the second housing 103 are both connected to the liquid inlet 1041 of the water pump module 104 via the switch module 106. The first liquid outlet 1042 of the water pump module 104 is connected to the liquid cooling system 110, and the second liquid outlet 1043 of the water pump module 104 is connected to the liquid inlet 1022 of the first housing 102 via the switch module 106.

[0074] In actual implementation, the liquid outlet 1021 of the first housing 102 and the liquid outlet 1031 of the second housing 103 are both connected to the switch module 106 via pipes. The switch module 106 is also connected to the liquid inlet 1041 of the water pump module 104 via pipes. The liquid outlets of the water pump module 104 include a first liquid outlet 1042 and a second liquid outlet 1043. The first liquid outlet 1042 of the water pump module 104 is connected to the liquid cooling system 110 via pipes, and the second liquid outlet 1043 of the water pump module 104 is connected to the switch module 106 via pipes. The switch module 106 is also connected to the liquid inlet 1022 of the first housing 102 via pipes.

[0075] In some embodiments, when the first channel is turned on, the liquid outlet 1021 of the first tank body 102 is turned on and connected to the liquid inlet 1041 of the water pump module 104; when the second channel is turned on, the liquid outlet 1031 of the second tank body 103 is turned on and connected to the liquid inlet 1041 of the water pump module 104; when the third channel is turned on, the liquid outlet 1031 of the second tank body 103 is turned on and connected to the liquid inlet 1041 of the water pump module 104, and the second liquid outlet 1043 of the water pump module 104 is turned on and connected to the liquid inlet 1022 of the first tank body 102.

[0076] In actual implementation, when the first channel is open, the cooling medium flows out of the liquid outlet 1021 of the first housing 102, passes through the switch module 106, flows to the liquid inlet 1041 of the water pump module 104, and then flows into the water pump module 104. Then, it flows into the liquid cooling system 110 through the first liquid outlet 1042 of the water pump module 104, thus forming a first channel for the cooling medium. When the second channel is open, the cooling medium flows out of the liquid outlet 1031 of the second housing 103, passes through the switch module 106, flows to the liquid inlet 1041 of the water pump module 104, and then flows into the water pump module 104. Then, it flows into the liquid cooling system 110 through the first liquid outlet 1042 of the water pump module 104, thus forming a second channel for the cooling medium. When the third channel is conductive, the coolant flows out of the liquid outlet 1031 of the second tank 103, passes through the switch module 106, and flows into the liquid inlet 1041 of the water pump module 104. The coolant then flows into the first tank 102 through the second liquid outlet 1042 of the water pump module 104 and the liquid inlet 1022 of the first tank 102, forming a third channel for the coolant. In actual implementation, the control module can control the conductivity of each channel by controlling the conductive state of the switch unit 106.

[0077] In some embodiments, see Figure 3 , Figure 31 is an optional structural diagram of a liquid replenishing device for a liquid cooling system provided in an embodiment of the present application. The switch module 106 includes a first switch 1061, a second switch 1062, and a third switch 1063. The first switch 1061 is connected between the liquid outlet 1021 of the first housing 102 and the liquid inlet 1041 of the water pump module 104. The second switch 1062 is connected between the liquid outlet 1031 of the second housing 103 and the liquid inlet 1041 of the water pump module 104. The third switch 1063 is connected between the second liquid outlet 1043 of the water pump module 104 and the liquid inlet 1022 of the first housing 102.

[0078] In actual implementation, the first switch 1061, the second switch 1062, and the third switch 1063 are all connected to a control module, which can control the conduction states of the first switch 1061, the second switch 1062, and the third switch 1063, respectively. Here, the first switch 1061, the second switch 1062, and the third switch 1063 can be ball valves. In actual implementation, if the first channel needs to be conductive, the control module controls the first switch 1061; if the second channel needs to be conductive, the control module controls the second switch 1062; and if the third channel needs to be conductive, the control module controls the third switch 1063.

[0079] In some embodiments, the control module 101 is also connected to the water pump module 104 and is further used to control the conduction of the first channel, the second channel or the third channel by controlling the conduction state of the water pump module 104 and the switch module 106 according to the liquid level.

[0080] In actual implementation, the control module is also connected to the water pump module 104 and controls the conduction of the first, second, or third channels by controlling the conduction states of the water pump module 104 and the switch module 106, respectively. Here, the water pump module 104 may include a rehydration pump having a liquid inlet and two liquid outlets. The control module can control the conduction between the liquid inlet of the rehydration pump and one of the two liquid outlets.

[0081] In some embodiments, when the first channel is open, the liquid outlet 1021 of the first box 102 is connected to the liquid inlet 1041 of the water pump module 104, and the liquid inlet 1041 of the water pump module 104 is connected to the first liquid outlet 1042; when the second channel is open, the liquid outlet 1031 of the second box 103 is connected to the liquid inlet 1041 of the water pump module 104, and the water pump module 104's liquid inlet 1041 is connected to the first liquid outlet 1042; when the third channel is connected, the liquid outlet 1031 of the second box body 103 is connected to the liquid inlet 1041 of the water pump module 104, the second liquid outlet 1043 of the water pump module 104 is connected to the liquid inlet 1022 of the first box body 102, and the liquid inlet 1041 of the water pump module 104 is connected to the second liquid outlet 1043.

[0082] In actual implementation, when the first channel is conductive, the switch module 106 is in a conductive state, so that the liquid outlet 1021 of the first housing 102 is conductively connected to the liquid inlet 1041 of the water pump module 104, and the liquid inlet 1041 of the water pump module 104 is conductively connected to the first liquid outlet 1042. When the second channel is conductive, the switch module 106 is in a conductive state, so that the liquid outlet 1031 of the second housing 103 is conductively connected to the liquid inlet 1041 of the water pump module 104, and the liquid inlet 1041 of the water pump module 104 is conductively connected to the first liquid outlet 1042. When the third channel is conductive, the switch module 106 is in a conductive state, so that the liquid outlet 1031 of the second housing 103 is conductively connected to the liquid inlet 1041 of the water pump module 104, and the liquid inlet 1041 of the water pump module 104 is conductively connected to the second liquid outlet 1043. In actual implementation, the control module controls the conduction of the first channel, the second channel or the third channel by controlling the conduction state of the switch module 106 and the water pump module 104 according to the liquid level of the first tank 102 .

[0083] In some embodiments, see Figure 4 , Figure 4 The liquid replenishing device 100 further includes a check valve 401 and an electric valve 402 connected between the water pump module 104 and the liquid cooling system 110 .

[0084] Here, check valve 401 is connected between the first liquid outlet of water pump module 104 and electric valve 402. Electric valve 402 is connected between check valve 401 and liquid cooling system 110. Check valve 402 is used to close when coolant flows from liquid cooling system 110 to check valve 402, preventing backflow of coolant. Electric valve 402 is an on-off valve installed before liquid cooling system 110. When electric valve 402 is open, coolant can flow into liquid cooling system 110. When electric valve 402 is closed, the coolant is blocked by electric valve 402.

[0085] In actual implementation, when the liquid cooling system 110 does not need to be replenished, specifically, when no replenishment command for the liquid cooling system 110 is received, the electric valve 402 is closed. When the first channel or the second channel needs to be opened, the control module controls the switch module 106 to connect the first tank 102 or the second tank 103 with the water pump module 104, and controls the liquid inlet 1041 of the water pump module 104 to connect with the first liquid outlet 1042. Then, the control module delays opening the electric valve 402 for a second period of time, that is, waits for the second period of time, to ensure sufficient pressure for the coolant to flow into the liquid cooling system 110. Here, the second period of time can be, for example, 3 seconds.

[0086] In some embodiments, see Figure 4 A filter 403 is also connected between the switch module 106 and the liquid inlet of the water pump module 104 to filter the coolant, ensuring a purer coolant flowing into the liquid cooling system 110 and preventing the influx of impurities. In some embodiments, a pressure gauge can be provided on the pipeline between the first liquid outlet of the water pump module 104 and the check valve 401 to monitor the pressure at the first liquid outlet of the water pump module 104.
