It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] During long-term operation, the cooling medium in a liquid cooling system will be lost, causing a drop in pressure and a decrease in cooling performance, necessitating periodic replenishment. However, if the supply-side flow channel is too small or clogged, replenishment may cause the pump outlet pressure to exceed safe limits. Furthermore, liquid cooling technology is susceptible to leakage. Leakage can lead to system performance degradation or malfunction, and the leaked liquid may damage other equipment. Therefore, an external replenishment system and a leak monitoring system are required to ensure long-term stable operation.

[0031] Based on this, this application provides a liquid cooling device, which can be referred to in conjunction with the above. Figure 1 and Figure 2 The liquid cooling equipment includes a liquid replenishment system 100 and a liquid cooling module 200; the liquid cooling module 200 includes a cooling pipe 210 and a heat exchange device 230 disposed on the cooling pipe 210; the inlet of the cooling pipe 210 is provided with a first temperature and pressure detection component, and the outlet of the cooling pipe 210 is provided with a second temperature and pressure detection component; the liquid replenishment system 100 includes a liquid replenishment tank 110 and a liquid replenishment pipe 120, the liquid replenishment tank 110 is provided with a liquid level sensor and a first temperature sensor 140; the first end of the liquid replenishment pipe 120 is connected to the liquid replenishment tank 110; the second end of the liquid replenishment pipe 120 is connected to the cooling pipe 210; and a liquid replenishment pump 150 is provided on the liquid replenishment pipe 120.

[0032] Compared with the prior art, the liquid cooling device provided in this application embodiment can monitor the liquid level, flow rate, and temperature in the replenishment tank 110 by setting a liquid level sensor and a first temperature sensor 140; by setting a first temperature and pressure detection component and a second temperature and pressure detection component at the liquid inlet and liquid outlet of the cooling pipe 210 respectively, the temperature and pressure signals of the liquid in the cooling pipe 210 can be monitored, and the pressure signal can be used to promptly report whether the liquid has leaked, thus avoiding overpressure, overtemperature, and liquid shortage during the operation of the liquid cooling device; at the same time, the replenishment pump 150 can also be started and stopped according to the temperature and pressure signals, ensuring the safety and stability of the replenishment process.

[0033] Please refer to the following in this embodiment: Figure 1 ,and Figure 2The top of the coolant tank 110 is equipped with a filling port 111 and an exhaust port (not shown). An external filling pipe 112 is connected to the filling port 111. The external filling pipe 112 is used to deliver coolant from an external filling device to the coolant tank 110. A level sensor is used to monitor the coolant level in the coolant tank. The level sensor includes a low level sensor 131 and a high level sensor 132. When the coolant level is lower than the low level alarm value, the low level alarm is triggered, reminding the maintainer that coolant needs to be added to the coolant tank. Liquid can be added to the coolant tank 110 through the external filling pipe. When the coolant level is higher than the high level alarm value, the high level alarm is triggered, reminding the user to stop adding coolant.

[0034] During the replenishment process, the first temperature sensor 140 detects the liquid temperature and then automatically adjusts the working state of the replenishment system 100 according to the set temperature range to keep the liquid temperature within a safe range.

[0035] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The liquid cooling equipment also includes a flow meter 160 installed on the liquid replenishment pipeline 120. The liquid replenishment pump 150 and the flow meter 160 are installed in sequence along the liquid flow direction in the liquid replenishment pipeline 120.

[0036] In this embodiment, the flow meter 160 is used to monitor the liquid flow rate through the replenishment line 120, thereby enabling precise control of the replenishment amount. By setting the flow meter 160, the accuracy and stability of the replenishment process can be further ensured, avoiding problems caused by excessive or insufficient replenishment. In addition, the flow meter 160 can also provide real-time data on the replenishment process, which helps in monitoring and optimizing the performance of the liquid cooling equipment.

[0037] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The liquid cooling equipment also includes a first shut-off valve 170 and a check valve 180 installed on the liquid replenishment pipeline 120. Along the liquid flow direction in the liquid replenishment pipeline 120, the liquid replenishment pump 150, the check valve 180, the first shut-off valve 170 and the flow meter 160 are installed in sequence.

[0038] In this embodiment, the first shut-off valve 170 is used to control the opening and closing of the replenishment pipeline 120, facilitating the disassembly and assembly of the replenishment system 100 and the liquid cooling module 200, as well as individual maintenance. The first shut-off valve 170 can also be closed to cut off the replenishment pipeline 120 when replenishment needs to be stopped, preventing liquid waste and equipment damage. The replenishment pump 150 provides the power source for the flow of liquid into the liquid cooling module 200, while the one-way valve 180 prevents backflow of coolant caused by the pressure inside the liquid cooling module 200 exceeding the liquid pressure of the replenishment system 100 when the replenishment pump 150 stops, ensuring the one-way and stability of the replenishment process. By setting the first shut-off valve 170 and the one-way valve 180, the safety and reliability of the replenishment process can be further improved, protecting the normal operation of the liquid cooling equipment.

[0039] In this embodiment, the liquid addition flow rate can be controlled by adjusting the opening degree of the first shut-off valve 170 or the output frequency of the replenishment pump 150, and according to the set value. Simultaneously, the external liquid addition equipment also needs to select appropriate liquid addition pipe diameter, liquid addition method, and liquid addition flow rate based on the characteristics of the liquid and the target liquid addition volume.

[0040] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The first temperature and pressure detection component includes a second temperature sensor 241 and a first pressure sensor 242; the second temperature and pressure detection component includes a third temperature sensor 251 and a second pressure sensor 252.

[0041] In this embodiment, the first pressure sensor 242 is used to collect the pressure of the liquid entering the liquid cooling equipment, and is used to calculate the liquid replenishment requirement and determine the stability of the flow rate; the second pressure sensor 252 is used to collect the pressure of the liquid exiting the liquid cooling equipment, and is used to determine whether the system pressure exceeds the operating range, and is indirectly used to calculate the pressure drop between the outlet and inlet of the liquid cooling equipment.

[0042] In this embodiment, the second temperature sensor 241 is used to collect the temperature of the liquid entering the liquid cooling equipment, and the third temperature sensor 251 is used to collect the temperature of the liquid exiting the liquid cooling equipment, so as to calculate the operating requirements of the liquid cooling equipment.

[0043] In this embodiment, the principle of starting and stopping the replenishment pump 150 is as follows:

[0044] (1) When a replenishment demand is generated, the second pressure sensor 252 detects that the pressure is outside the reasonable range and will not start the replenishment pump 150. Only when the replenishment demand is met, the second pressure sensor 252 detects that the pressure is within the preset reasonable pressure range and starts the replenishment pump 150 to inject liquid.

[0045] (2) After the start-up conditions of the replenishment pump 150 are met, the replenishment pump 150 stops replenishing liquid when the first pressure sensor 242 detects that the pressure meets the preset pressure value.

[0046] (3) When the running time of the replenishing pump 150 exceeds the preset maximum running time, in order to protect the device, the replenishing pump 150 is stopped to replenish liquid. After the minimum stop time of the replenishing pump 150 is met, the pressure is re-detected and the replenishing demand is calculated, and then the replenishing pump 150 is controlled.

[0047] (4) If the replenishment pump 150 operates continuously for more than N times within the preset first time period, and the pressure detected by the first pressure sensor 242 still cannot meet the target replenishment pressure, the replenishment pump 150 is restricted from starting and an alarm is triggered for replenishment pump 150 failure.

[0048] (5) If the number of continuous operation of the replenishment pump 150 exceeds the preset value M times within the preset second time period, the liquid cooling equipment leakage alarm will be triggered.

[0049] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The liquid cooling module 200 also includes a filter device 260 installed on the cooling pipe 210; the inlet end of the filter device 260 is provided with a second shut-off valve 261, and the outlet end of the filter device 260 is provided with a third shut-off valve 262; the second end of the replenishment pipe 120 is connected between the second shut-off valve 261 and the inlet of the cooling pipe 210.

[0050] In this embodiment, the filter device 260 is used to filter out impurities and particulate matter in the coolant, ensuring the purity of the coolant and the normal operation of the liquid cooling equipment. By setting up the filter device 260, the service life of the liquid cooling equipment can be further extended and the failure rate reduced. The second shut-off valve 261 and the third shut-off valve 262 are used to control the opening and closing of the inlet and outlet of the filter device 260, respectively, facilitating the disassembly, assembly, and individual maintenance of the filter device 260. When it is necessary to clean or replace the filter device 260, the inlet and outlet pipelines of the filter device 260 can be cut off by closing the second shut-off valve 261 and the third shut-off valve 262, preventing liquid leakage at both ends of the filter device 260. The second end of the replenishment pipeline 120 is connected between the second shut-off valve 261 and the inlet of the cooling pipeline 210, making the replenishment process more flexible and convenient. By setting up the filter device 260, the second shut-off valve 261, and the third shut-off valve 262, the reliability and stability of the liquid cooling equipment can be further improved, protecting the normal operation of the liquid cooling equipment. Specifically, the filter device 260 can be a Y-type filter.

[0051] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3The liquid cooling module 200 also includes a fourth shut-off valve 271 and a fifth shut-off valve 272. The fourth shut-off valve 271 is located at the liquid inlet of the cooling pipe 210; the fifth shut-off valve 272 is located at the liquid outlet of the cooling pipe 210.

[0052] In this embodiment, by setting the fourth shut-off valve 271 and the fifth shut-off valve 272, the on / off of the cooling pipe 210 can be further controlled, which facilitates the disassembly and assembly of the liquid cooling module 200 and its individual maintenance, as well as its connection to an external load.

[0054] In this embodiment, the expansion tank 280 is used to absorb and release the volume change of the coolant caused by temperature changes during the heating process, buffer the pressure fluctuation of the liquid cooling module 200, eliminate water hammer, stabilize pressure and unload, and further improve the adaptability and stability of the liquid cooling equipment.

[0055] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The liquid cooling module 200 also includes a circulation pump 290 disposed on the cooling pipe 210, and the circulation pump 290 is disposed between the expansion tank 280 and the heat exchange device 230.

[0056] In this embodiment, the circulating pump 290 drives the coolant to circulate within the liquid cooling module 200, ensuring that the coolant can uniformly and quickly remove heat generated by the external load and transfer the heat to the heat exchange device 230 for dissipation. By setting up the circulating pump 290, the heat dissipation efficiency and performance of the liquid cooling equipment can be further improved, ensuring the normal operation and stability of the liquid cooling equipment. The maximum head provided by the circulating pump 290 can be reflected by the pressure collected by the second pressure sensor 252.

[0057] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The liquid cooling module 200 also includes a manual replenishment valve 211 and a manual drain valve 212 disposed on the cooling pipe 210. The manual replenishment valve 211 is disposed near the liquid inlet of the cooling pipe 210, and the manual drain valve 212 is disposed between the expansion tank 280 and the circulation pump 290.

[0058] In this embodiment, the manual replenishment valve 211 is used to manually replenish coolant to the liquid-cooled module 200 when needed, serving as an interface for manual replenishment and ensuring the normal operation of the liquid-cooling equipment. The manual drain valve 212 is used to manually drain coolant from the liquid-cooled module 200 when needed, serving as an interface for manual draining and facilitating cleaning and maintenance of the liquid-cooled module 200. By providing the manual replenishment valve 211 and the manual drain valve 212, the flexibility and operability of the liquid-cooling equipment can be further improved, meeting different user needs.

[0061] In this embodiment, the compressor 320 draws in low-temperature, low-pressure superheated refrigerant vapor from the heat exchange device 230, compresses it to discharge high-temperature, high-pressure superheated refrigerant vapor, and flows into the condenser assembly 330 to exchange heat with the heat exchange medium air, gradually condensing it into high-pressure subcooled liquid refrigerant. After being throttled and depressurized by the throttling device 340, it becomes a low-temperature, low-pressure, mostly liquid two-phase refrigerant, which enters the heat exchange device 230 at a suitable flow rate to undergo phase change evaporation and absorb heat, reducing the temperature of the object being cooled and achieving refrigeration. After absorbing heat, the refrigerant becomes superheated vapor and is drawn back in by the compressor 320, and the refrigerant module 300 continuously repeats this cycle.
