Technical Field

The cooling equipment for shipboard data center compartments uses seawater as its primary cold source, must meet marine environmental conditions, and must possess uninterrupted cooling capabilities under year-round and global environmental conditions.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 2 , 5 As described in 6 and 7, the seawater-source marine integrated server liquid cooling system 1 includes:

[0038] The seawater-source marine integrated server liquid cooling system 1 is a cooling and heat exchange device that uses seawater with a rated cooling capacity of over 20KW as a condensing cold source and can provide stable low-temperature ethylene glycol coolant to the data server. Figure 2 As shown, the seawater-source marine integrated server liquid cooling device 1 mainly consists of two main modules: a seawater source compression and condensation module 101 and an ethylene glycol cooling module 102. The environmental control module control box 2 described in Example 1 is connected to the seawater source compression and condensation module 101 and the ethylene glycol cooling module 102 respectively. The three modules, namely the seawater source compression and condensation module 101, the ethylene glycol cooling module 102 and the environmental control module control box 2, can be integrated and configured in a box frame 103.

[0039] like Figure 4 As shown, the frame enclosure 103 is a cubic cabinet structure, with the entire frame made of 316L stainless steel. The front of the enclosure is divided into four sections: the upper left section is the environmental control module control box 2, and the other three sections are removable panels 1301. Removable panels are also located on the left, right, top, and rear of the enclosure for easy maintenance and replacement of all unit components and piping. The interior of the enclosure is divided into two layers. The upper layer mainly houses the compression condensing unit and the constant pressure water supply unit, while the lower layer contains the ethylene glycol cooling unit and the shell-and-tube condenser 1103, one of the main components of the seawater-sourced compression condensing module 101.

[0040] The integrated server liquid cooling system 1 includes: a seawater source compression and condensation module 101 and an ethylene glycol cooling module 102; the integrated server liquid cooling system 1 and the environmental control module control box 2 are integrated and configured in a box frame 103; the seawater source compression and condensation module 101 and the ethylene glycol cooling module 102 are connected through Freon refrigerant pipelines.

[0041] The frame box 103 is a two-layer box structure. The environmental control module control box 2, the seawater source compression and condensation module 101 and the ethylene glycol cooling module 102 are arranged inside the frame box 103. The front, back and side outer surfaces of the frame box 103 are equipped with detachable panels 1301.

[0042] like Figure 2As shown, the seawater source compression and condensation module 101 adopts a dual-cycle fluorine refrigeration system design, including two fluorine refrigeration systems. The two fluorine refrigeration systems share a single condenser 1103. The first fluorine refrigeration system includes a first refrigeration compressor 1101, a condenser 1103, a first thermostatic expansion valve 1104, and a first evaporator 1106, etc., connected by copper pipes to form a closed fluorine refrigeration system. The second fluorine refrigeration system includes a second refrigeration compressor 1102, a condenser 1103, a second thermostatic expansion valve 1105, and a second evaporator 1107, etc., connected by copper pipes to form a closed fluorine refrigeration system. The first and second refrigeration compressors 1101... The refrigerant is compressed into a high-temperature, high-pressure gas in 101 and 1102. It exchanges heat with the external seawater in condenser 1103 and becomes a high-pressure liquid refrigerant. After being throttled by the first and second thermal expansion valves 1104 and 1105, it becomes a low-pressure, low-temperature gas-liquid two-phase mixture. It enters the first and second evaporators 1106 and 1107 respectively to exchange heat with the ethylene glycol coolant. The low-temperature, low-pressure refrigerant vaporizes and absorbs heat to become a low-pressure gaseous refrigerant, thereby reducing the temperature of the ethylene glycol coolant passing through the other side of the first and second evaporators 1106 and 1107. The generated low-pressure gas is then drawn into the first and second compressors 1101 and 1102 again, and so on, continuously circulating for refrigeration. To accommodate the dimensions of the seawater source marine integrated server liquid cooling system 1, the first and second refrigeration compressors 1101 and 1102 are both scroll-type vertical compressors, arranged side-by-side in the upper left corner of the housing frame 103. The first refrigeration compressor 1101 is connected to the first refrigerant inlet of the condenser 1103 via refrigerant pipelines, and the second refrigeration compressor 1102 is connected to the second refrigerant inlet of the condenser 1103. The condenser 1103 can be, for example, a shell-and-tube condenser. Parallel dual hot gas bypass pipelines are also provided, with a pair of hot gas bypass valve groups on each bypass pipeline, namely, the first and second hot gas bypass valve groups 1108 and 1109, and the second and second hot gas bypass valve groups 1110 and 1111. Condenser 1103 has a large heat exchange capacity and is also the largest component in the unit. To reduce the overall size of condenser 1103 while still providing good resistance to seawater corrosion, a shell-and-tube condenser with a dual-fluorine-seawater heat exchange structure was selected. This design satisfies the requirements of two relatively independent fluorine refrigerant pipelines, reduces the number of condensers 1103, and lowers the overall size of condensers 1103. Furthermore, the internal seawater pipelines of the dual-fluorine-seawater shell-and-tube condenser 1103 use high-quality B30 copper-nickel tubing, and the end caps are made of cast aluminum bronze, providing excellent corrosion resistance and meeting the corrosion resistance requirements of the seawater cold source. Considering the large size and weight proportion of the shell-and-tube condenser, it is positioned on the lower right side of the enclosure to balance the overall weight and center of gravity of the unit.To meet the refrigeration requirements under different seawater temperature conditions in global navigation areas, the rated design temperature of the seawater inlet for the condenser 1103 is selected to be 36℃. A first condensing pressure regulating valve 1112 and a second condensing pressure regulating valve 1113 are installed in parallel on the seawater pipeline. Seawater corrosion resistant first and second seawater temperature sensors 1114 and 1115 are respectively installed on the inlet and outlet seawater pipelines. At the same time, a seawater pressure sensor 1116 is installed at the seawater inlet. A first antifreeze relief valve 1117 is installed on the inlet seawater pipeline, and a second antifreeze relief valve 1118 is installed on the outlet seawater pipeline. After exchanging heat with seawater, the fluorinated refrigerant exits from the top of the condenser and returns to the upper left side of the cabinet via pipes. It then passes through a liquid level indicator, a shut-off valve, a filter dryer, refrigeration solenoid valves 1119 and 1120, and thermal expansion valves 1104 and 1105 before entering brazed plate evaporators 1106 and 1107 to exchange heat with ethylene glycol coolant. Considering that the liquid cooling medium is ethylene glycol solution, which has a certain corrosiveness to non-ferrous metals, and that the upper left side of the device shares space with the environmental control module control box 2 and refrigeration compressors 1101 and 1102, the overall size of the two sets of evaporators 1106 and 1107 is controlled within a space range of 200mm × 300mm × 400mm. The design selects brazed plate evaporators made of 316 stainless steel with a compact structure. At the same time, the heat exchange capacity of a single evaporator 1106 or 1107 must be greater than the compression and refrigeration capacity requirement of a single compressor 1101 or 1102.

[0043] The main components of the seawater source compression condensation module 101 are distributed in the upper left and lower right layers of the frame box 103, and each component is connected to form a loop through pipelines.

[0051] Preferably, the ethylene glycol cooling module 102 further includes: a flow sensor 1208 and an automatic vent valve 1223. The flow sensor 1208 is installed on the return liquid main pipe and is connected in series with the first evaporator 1106 and the first ethylene glycol return liquid filter 1209.

The automatic vent valve 1223 is installed on the combined outlet main pipe of the parallel first ethylene glycol return liquid filter 1209 and the second ethylene glycol return liquid filter 1210.

[0052] Here, the ethylene glycol cooling module 102 mainly consists of a constant pressure replenishment and exhaust component on the upper right side of the cabinet and two ethylene glycol supply circulation pumps 1201 and 1202 on the lower left side, an electric bypass valve 1203 between the supply and return mains, a water pressure sensor 1204 on the supply line, a pressure sensor 1205 on the return line, a temperature sensor 1206 at the outlet of the supply line, a temperature sensor 1207 at the inlet of the return line, a flow sensor 1208 on the return main, two ethylene glycol return filters 1209 and 1210 connected in parallel on the return main, an electric butterfly valve 1211 at the inlet of filter 1209 and an electric butterfly valve 1212 at the outlet, an electric butterfly valve 1213 at the inlet of filter 1210 and an electric butterfly valve 1214 at the outlet, and a pressure sensor 1215 on the inlet main and a pressure sensor 1216 on the outlet main of the parallel filters. To optimize and reduce the overall size while improving the reliability of the cooling module, parallel backups were implemented for key and fault-prone components of the liquid supply module, namely the glycol supply circulation pumps 1201 and 1202, and the glycol return filters 1209 and 1210. Backup functionality was also implemented in the control logic, as described in Example 4. The inlet and outlet mains are a single circulation pipeline. To ensure sufficient heat exchange and mixing of the supply and return liquids, a buffer mixing tank 1217 was installed before the glycol supply circulation pumps 1201 and 1202.

[0053] Specifically, the constant pressure liquid replenishment and venting component, one of the main components of the ethylene glycol cooling module 102, is mainly located in the upper right area of ​​the cabinet 103. The constant pressure liquid replenishment and venting component includes: a liquid filling tank 1218, a liquid level sensor 1219 on the liquid filling tank, a closed expansion tank 1220, a liquid replenishment pump 1221, a water replenishment filter 1222, an automatic venting valve 1223, a pressure sensor 1224 for the liquid supply pipeline system, a first automatic water replenishment valve 1225 and a second automatic water replenishment valve 1226, and liquid filling pipelines, etc.

[0054] The automatic vent valve 1223 is installed on the combined outlet main of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210 connected in parallel. The upper interface of the filling tank 1218 is connected to the automatic vent valve 1223 via a pipeline. The bottom interface of the filling tank 1218 is connected to the ethylene glycol coolant recovery port and the ethylene glycol coolant replenishment pipe, respectively. The filling pipeline is connected to the bottom outlet of the filling tank 1218 and the inlet of the buffer mixing tank 1217. The replenishment pump 1221 is installed on the filling pipeline. An automatic water replenishment valve 1225 is installed between the inlet of the replenishment pump 1221 and the outlet of the filling tank 1218. A water replenishment filter 1222 and an automatic water replenishment valve 1226 are connected in series on the outlet pipeline of the replenishment pump 1221. The outlet of the automatic water replenishment valve 1226 is connected to the buffer mixing tank 1217 via a pipeline. The inlet pipe of tank 1217 is connected; a liquid level sensor 1219 is installed on the liquid addition tank 1218 and is connected to the environmental control module control box 2 via a signal line; the closed expansion tank 1220 is located at the lower left corner of the ethylene glycol cooling module 102 and above the liquid supply circulation pumps 1201 and 1202. The bottom interface of the closed expansion tank 1220 is connected to the combined inlet liquid supply main of the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202 via a pipeline. At the same time, a liquid supply pipeline system pressure sensor 1224 is installed on the pipeline between the inlet of the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202 and the bottom interface of the closed expansion tank 1220. The pipeline system pressure sensor 1224 is connected to the environmental control module control box 2 via a signal line.

[0055] The main power supply module 201, the main control board 202 containing the microcontroller, and the low-voltage control power supply module 203 are all arranged inside the environmental control module control box 2 and interconnected via cables and signal lines; the touch LCD display 204 is arranged on the front panel of the environmental control module control box 2; a water leakage detection rope 9 is installed around the bottom of the frame box 103; the water leakage detection rope 9 around the bottom of the frame box 103 is connected to the environmental control module control box 2 via signal lines; all sensors inside the seawater source marine integrated server liquid cooling system 1 are: inlet seawater temperature sensor 1114, outlet seawater temperature sensor 1115, inlet seawater pressure sensor 1117, supply pipeline water pressure sensor 1204, return pipeline water pressure sensor 1205, supply pipeline outlet temperature sensor 1206, return pipeline temperature sensor 1207, electromagnetic flow sensor 1208, third pressure sensor 1215, and fourth... Pressure sensor 1216 at the filter outlet main pipe and pressure sensor 1224 in the liquid supply pipeline system are both connected to the environmental control module control box 2 via signal lines. All electrically driven components inside the seawater source marine integrated server liquid cooling system 1, including refrigeration compressor 1101, refrigeration compressor 1102, hot gas bypass valve group 1108, hot gas bypass valve group 1109, hot gas bypass valve group 1110, hot gas bypass valve group 1111, refrigeration solenoid valve 1119, refrigeration solenoid valve 1120, ethylene glycol supply circulation pump 1202, ethylene glycol supply circulation pump 1203, electric bypass valve 1203, filter inlet electric butterfly valve 1211, filter outlet electric butterfly valve 1212, filter inlet electric butterfly valve 1213, filter outlet electric butterfly valve 1214, replenishment pump 1221, automatic water replenishment valve 1225, and automatic water replenishment valve 1226, are all connected to the environmental control module control box 2 via signal control lines.

[0056] Here, the constant pressure replenishment and venting component, one of the main components of the ethylene glycol cooling module 102, is mainly located in the upper right area of ​​the cabinet. It mainly consists of a liquid filling tank 1218, a liquid level sensor 1219 on the liquid filling tank 1218, a closed expansion tank 1220, a replenishment pump 1221, a water replenishment filter 1222, an automatic venting valve 1223, a pressure sensor 1224 for the liquid supply pipeline system, automatic water replenishment valves 1225 and 1226, and supporting pipelines. The closed expansion tank 1220 contains an inflatable diaphragm. When the pressure inside the system increases due to temperature changes or other reasons, water from the device enters the expansion tank 1220, and the diaphragm contracts, balancing the pressure on both sides. When the pressure inside the device decreases due to temperature changes or other reasons, water from the expansion tank 1220 enters the device, and the diaphragm expands, balancing the pressure on both sides, thus automatically stabilizing the device pressure. During normal use, the device can effectively remove gas from the ethylene glycol cooling module 102 via the automatic vent valve 1223. The constant pressure replenishment and venting component also has the function of automatically replenishing liquid if it detects a possible leak that could cause the flow rate and pressure to drop too low. The specific logic is described in Example 4.

[0057] like Figure 3As shown, the environmental control module control box 2 is located on the left outer side of cabinet 103. It mainly consists of a main power supply module 201, a main control board 202 containing a microcontroller, a low-voltage control power supply module 203, a touch LCD display 204, and external sampling sensors. The main control board 202 is designed according to military environmental control equipment standards, meeting the requirements of operating at -40℃ to +55℃. It uses a high-speed MCU embedded microcontroller to process data. All input interfaces are equipped with necessary abnormal protection devices. The PCB board is made of FR-4 epoxy fiberglass cloth laminate with high thermal stability and high mechanical strength. All interfaces are located on the front, double-sided coated with three-proof glue, and high-standing components are fixed with glue. It has the ability to resist vibration, impact, moisture, salt spray, and mold, meeting the requirements of marine environmental conditions. The main sampling sensors configured in the device include: a seawater temperature sensor 1114 installed on the seawater inlet main pipe to monitor the inlet seawater temperature; a second seawater temperature sensor 1115 installed on the seawater outlet main pipe to monitor the seawater temperature after heat exchange through the condenser 1103; the heat exchange capacity of the condenser 1103 can be controlled by calculating the difference between the heat-exchanged seawater temperature and the inlet seawater temperature; a second seawater pressure sensor 1116 installed on the seawater inlet main pipe to monitor whether seawater flows normally into the condenser, which can be used as one of the necessary parameters for the normal start-up and operation of the device; a supply pipe outlet temperature sensor 1206 installed on the ethylene glycol coolant supply main pipe to monitor the temperature supplied to the data server, which is also a major parameter for regulating the supply temperature; a temperature sensor 1207 installed on the ethylene glycol coolant return main pipe to monitor the temperature of the ethylene glycol coolant after heat exchange through the liquid cooling plate in the server; and a supply pipe water pressure sensor 1204 installed on the ethylene glycol coolant supply main pipe to monitor the ethylene glycol solution supply pressure. The electromagnetic flow sensor 1208, installed on the return water main pipe, can monitor the total flow rate of ethylene glycol coolant in real time. By combining this with the difference between the inlet and outlet water temperatures of the ethylene glycol coolant, the server's load cooling demand can be obtained, thereby controlling the device to adjust the cooling capacity. The third pressure sensor installed at the inlet / outlet ends of the ethylene glycol coolant filters 1209 and 1210... Force sensor 1215 and fourth pressure sensor 1216 can monitor the pressure at both ends of the filter and transmit it to the environmental control module control box 2 in real time. The environmental control module control box 2 obtains the pressure drop value of the first ethylene glycol supply circulation pump 1201 and the second ethylene glycol supply circulation pump 1202 by subtracting the two values. It compares the pressure drop value with the recorded initial pressure drop value. When the pressure drop threshold is exceeded, an alarm is displayed to show that the first ethylene glycol supply circulation pump 1201 and the second ethylene glycol supply circulation pump 1202 are clogged, and corresponding measures are automatically started to deal with the fault.The pipeline system pressure sensor 1124, installed on the constant pressure pipeline of the device, can monitor the minimum pressure value of the ethylene glycol pipeline and can serve as a necessary parameter for determining whether liquid replenishment is needed; the liquid level sensor 1219, installed in the liquid tank 1218, can monitor the level of the spare ethylene glycol solution in the liquid tank 1218, and can trigger an audible and visual alarm to notify liquid replenishment when the level is lower than the minimum allowable solution level; the leakage detection rope 9, arranged around the bottom of the cabinet 103, can monitor whether there is a leak inside the device; the phase sequence protector in the power supply module enables phase loss detection when the device is started; the environmental control module control box 2 connects to the CAN bus. The system uses either a wired or RS485 interface to receive signals from the refrigeration compressors 1101 and 1102 regarding exhaust temperature and high / low pressure alarms, as well as overload signals from the ethylene glycol supply circulation pumps 1201 and 1202. This allows for monitoring the operating status and fault information of compressors 1101 and 1102, and ethylene glycol supply pumps 1201 and 1202, and the implementation of corresponding measures for each fault. The environmental control module control box 2, by receiving real-time data from the aforementioned sensors and key components, can perform major fault alarms, automatic backup switching, and internal leakage detection, ultimately enabling the system to operate unattended and automatically handle major faults.

[0058] In this implementation, by adopting high-efficiency components such as a scroll vertical compressor 1101, a shell-and-tube condenser 1103 with a double-fluorine-seawater heat exchange structure, and small brazed plate evaporators 1106 and 1107, the overall size of key large-volume components of the device is reduced. At the same time, the positions of components with a large weight ratio are reasonably arranged, forming a compact, easy-to-maintain, and efficient seawater-source marine integrated server liquid cooling device 1.

[0059] In this implementation, necessary sensors are installed in key parts of the seawater source marine integrated server liquid cooling system 1 to comprehensively monitor key operating parameters of the system. The signals from various sensors are transmitted to the environmental control module control box 2 in real time. The algorithm software built into the control box 2 enables comprehensive automatic monitoring of the system 1, and can automatically identify major faults and automatically initiate corresponding fault handling measures, enabling the system to have the ability to operate unattended and automatically handle faults.

[0060] Example 2

[0061] like Figure 1 As shown, based on Embodiment 1, this example can combine the seawater-source marine integrated server liquid cooling device 1 of Embodiment 1 to provide a marine data center cabin environment control system, including:

[0062] host computer,

[0063] An environmental control module control box 2 is installed outside the ship's data center cabin. The environmental control module control box 2 is remotely wired or wirelessly connected to the host computer.

[0064] The seawater source air conditioner 4 and the air environment sensor 8 of the part to be monitored are installed in the cabin of the ship's data center. The air environment sensor 8 and the seawater source air conditioner 4 are respectively connected to the environmental control module control box 2.

[0065] The duct fan 5, electric fireproof damper 6, and air filter 7 are installed in the ship's data center compartment. The duct fan 5, electric fireproof damper 6, and air filter 7 are respectively connected to the environmental control module control box 2.

[0066] Leakage detection rope 9 is installed around easily leaking equipment in the ship's data center compartment; Leakage detection rope 9 is connected to environmental control module control box 2.

[0067] A seawater-source marine integrated server liquid cooling system 1 is installed outside the ship's data center cabin and is connected to the environmental control module control box 2.

[0068] The data servers inside the ship's data center compartment are equipped with liquid-cooled cold plates, specifically data servers 901 and 902 (labeled).

[0069] The seawater-source marine integrated server liquid cooling system 1 outside the data center cabin is connected to the liquid cooling plate inside the server in the ship's data center cabin via an external liquid supply pipeline.

[0070] A backup cold source is installed outside the data center cabin, and the backup cold source is connected to the external liquid supply pipeline through a liquid-cooled power supply switching electric valve 10.

[0071] Preferably, the seawater-source marine integrated server liquid cooling device 1 includes: a compression condensation module 101 and an ethylene glycol cooling module 102, wherein the compression condensation module 101 is connected to the ethylene glycol cooling module 102, and the ethylene glycol cooling module 102 is connected to an external liquid supply pipeline.

[0072] Each liquid-cooled cold plate in the data server is equipped with a terminal control unit 3 at its inlet and outlet. The terminal control unit 3 is connected to the ethylene glycol cooling module 102. The terminal control unit 3 includes: an inlet water pressure sensor 304, an outlet water pressure sensor 303, an outlet water temperature sensor 302, and a hydraulic balance valve 301. The inlet water pressure sensor 304 is connected to the inlet of the liquid-cooled cold plate, and the outlet water pressure sensor 303, the outlet water temperature sensor 302, and the hydraulic balance valve 301 are connected in series. The outlet water pressure sensor 303 is connected to the outlet of the liquid-cooled cold plate. The pressure sensor 304, the outlet water pressure sensor 303, the outlet water temperature sensor 302, and the hydraulic balance valve 301 are connected to the ethylene glycol cooling module 102 through external liquid supply pipelines.

[0073] The environmental control module control box 2, integrated with the seawater-source marine integrated server liquid cooling device 1, is mounted on a single frame. Its main functions are: to achieve complete logical control of the seawater-source marine integrated server liquid cooling device 1 (detailed control logic is described in Example 2); to comprehensively monitor the air temperature, humidity, and cleanliness of the ship's data center cabin by installing multiple air environment sensors 8 (e.g., three sensors) at the monitored locations within the cabin; and to automatically activate the seawater-source air conditioner 4 if the air environment sensors 8 detect that the air temperature and humidity exceed set values. Furthermore, it controls the ventilation system of the ship's data center cabin, consisting of the duct fan 5, electric fireproof damper 6, and air filter 7, to automatically achieve 15 minutes of ventilation every 4 hours to ensure the ship's air quality. The data center compartment may emit toxic and harmful gases. In the event of a fire, when the environmental control module control box 2 receives a fire alarm from the host computer, it immediately stops the operation of the seawater source air conditioner 4 and the duct fan 5 in the ship's data center compartment and closes the electric fire damper 6. The environmental control module control box 2 can receive leakage signals from the leakage detection ropes 9 installed around easily leaking equipment (such as data servers and seawater source air conditioners 4 with water pipes) in the ship's data center compartment, issue leakage audible and visual alarm information, and forward it to the host computer to notify relevant personnel. The environmental control module control box 2 can also monitor the status of the seawater source marine integrated server liquid cooling device 1, the seawater source air conditioner 4 in the ship's data center compartment, and the duct fan 5, and implement backup operation through internal logic to improve the operational reliability and survivability of the entire system. The specific control logic is as follows:

[0074] Step S1: After the environmental control module control box 2 detects that the seawater source marine integrated server liquid cooling device 1 cannot operate normally or cannot be over-controlled in an emergency, it issues a local audible and visual alarm. The screen of the environmental control module control box 2 displays the specific faulty device and simultaneously alarms the host computer.

[0075] Step S2: The environmental control module control box 2 automatically starts the seawater source air conditioner 4 and the duct fan 5 in the ship's data center compartment in an emergency.

[0076] Step S3: The environmental control module control box 2 monitors the operating status of the seawater source air conditioner 4 and the duct fan 5 in the ship's data center cabin and the air temperature inside the cabin in real time. When any one of the equipment in the seawater source air conditioner 4 and the duct fan 5 in the ship's data center cabin fails to operate, or when the temperature inside the data center cabin exceeds the threshold requirement, local audible and visual alarm information will be issued, the specific faulty equipment will be displayed on the screen, and an alarm will be sent to the host computer at the same time.

[0077] Step S4, the environmental control module control box 2 is used to request the host computer to turn on the ship's backup cold source and open the liquid cooling supply conversion electric valve 10 when either the seawater source air conditioner 4 or the duct fan 5 in the ship's data center cabin fails continuously and the temperature in the ship's data center cabin exceeds the threshold, while simultaneously triggering a continuous alarm.

[0078] Step S5: The environmental control module control box 2 is used to automatically cut off the liquid cooling supply switching electric valve 10 after the seawater source marine integrated server liquid cooling supply device 1 has been repaired and can continue to operate for a specified time. After the specified time of continuous operation, the system's audible and visual alarm stops, and a normal operation signal is sent to the host computer. The host computer controls the shutdown of the audible and visual alarm information activated in step S3, shuts down the seawater source air conditioner 4 and duct fan 5 activated in step S2, and shuts down the backup cold source and alarm activated in step S4.

[0079] The marine integrated liquid cooling system for seawater-sourced servers is a compact, specially developed, highly reliable, unattended, and automatically and rapidly responding system for handling major faults. It provides ethylene glycol coolant and serves data servers. Figure 2 As shown, the seawater-source marine integrated server liquid cooling system 1 mainly consists of a compression condensation module 101 and an ethylene glycol cooling module 102. See Example 2 for a detailed description.

[0080] The terminal control unit 3 mainly consists of an inlet water pressure sensor 304, an outlet water pressure sensor 303, an outlet water temperature sensor 302, and a hydraulic balance valve 301. The inlet water pressure sensor 304, outlet water pressure sensor 303, and outlet water temperature sensor 302 transmit the monitored data to the environmental control module control box 2 in real time. This enables real-time monitoring of the inlet and outlet water pressure and outlet water temperature of the liquid-cooled cold plates in each data server 901 and 902. Simultaneously, the hydraulic balance valve 301, located at the return water outlet, adjusts and locks the liquid supply to the liquid-cooled cold plates in each data server to ensure that the ethylene glycol refrigerant flow rate to each data server's liquid-cooled cold plates meets the requirements.

[0081] The seawater-source air conditioner 4 for the ship's data center compartment is mainly used for temperature and humidity regulation of the air environment inside the compartment, providing a thermal environment that meets the operating requirements of the equipment. The seawater-source air conditioner 4 for the ship's data center compartment mainly consists of two compressors, one shell-and-tube condenser, one evaporator, one electric heater, two low-noise centrifugal fans, two thermal expansion valves, several solenoid valves, a drying filter, and an electrical control box. This equipment uses seawater as the condensing medium and employs a liquid-gas exchange evaporator with a large airflow rate. The evaporation temperature is controlled by an electrically operated thermal expansion valve, achieving a high sensible heat ratio, large air volume, and small enthalpy difference, making it a dedicated air conditioner for ship's data center compartments. The dual condenser units improve the reliability of the entire unit. Furthermore, it can be activated as an emergency air conditioning system when the seawater-source integrated marine server liquid cooling unit 1 fails and shuts down.

[0082] The ship's data center compartment is equipped with a duct fan 5, an electric fire-resistant damper 6, and an air filter 7. This system automatically activates the duct fan 5 every 4 hours, opening the electric fire-resistant damper 6 for 15 minutes of ventilation. It also periodically filters and purifies any potentially toxic or harmful gases generated within the data center compartment before expelling them outside, maintaining air cleanliness. Furthermore, it can be activated as an emergency cooling system in case of a malfunction or shutdown of the seawater-sourced integrated marine server liquid cooling unit 1.

[0083] Three air environment sensors can be installed in a typical monitored area of ​​a ship's data center compartment to comprehensively monitor the air temperature, humidity, and cleanliness inside the compartment, and send the real-time monitoring data to the processing, display, and recording system.

[0084] Leakage detection ropes 9 are installed around equipment prone to leakage in the ship's data center compartment. When liquid leaks from the supply line or internal pipe accessories into the deck of the ship's data center compartment, the leakage detection ropes 9 detect the leak and send a leakage signal to the environmental control module control box 2. The environmental control module control box 2 issues an audible and visual alarm and displays fault information on the screen, while simultaneously sending the corresponding fault signal to the host computer.

[0085] The air environment sensor 8, water leakage detection rope 9, and water inlet pressure sensor 304, water outlet pressure sensor 303, and water outlet temperature sensor 302 in the ship's data center compartment can comprehensively monitor the parameters related to environmental control in the ship's data center compartment. When a fault is detected, an automatic audible and visual alarm will be triggered. The fault type and handling measures will be highlighted on the display screen of the environmental control module control box 2, and the information will be reported to the host computer in a timely manner, realizing the functions of unattended operation and automatic rapid response to handle critical faults.

[0086] Example 3

[0087] Based on Example 1, the seawater source compression and condensation module 101 adopts a dual-cycle fluorine refrigeration system design. Each fluorine refrigeration system includes complete refrigeration compressors 1101 and 1102, condenser 1103, thermostatic expansion valves 1104 and 1105, evaporators 1106 and 1107, etc. The equipment has two independent fluorine refrigeration systems that do not interfere with each other during operation. The two cycle fluorine refrigeration systems can achieve high-reliability operation by backing each other up through the following logic control:

[0088] Step S1, the environmental control module control box 2 is used to select the one with the shorter cumulative running time of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 to start first when the equipment is initially started, based on the cumulative running time of each of the first refrigeration compressor 1101 and the second refrigeration compressor 1102.

[0089] Step S2: The environmental control module control box 2 is used to automatically calculate the total load heat based on the temperatures collected by the liquid supply outlet temperature sensor 1206 and the return liquid temperature sensor 1207 in the ethylene glycol cooling module 102, and the total liquid supply flow rate collected by the return liquid flow sensor 1208. When the total load heat is greater than half of the cooling capacity (e.g., set to 10kW), the other unstarted refrigeration compressor of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 will be turned on. During operation, when the detected load heat is less than or equal to the cooling capacity... If the refrigeration compressor operates for more than 3 minutes after reaching half its capacity (tentatively set at 10kW), it can be stopped. Normally, the seawater source compression and condensation module 101 selects the refrigeration compressor 1101 or the second refrigeration compressor 1102 that has been shut down for a longer period based on the calculated total load heat, ensuring that at least one refrigeration compressor remains operational. The first refrigeration compressor 1101 and the second refrigeration compressor 1102 are controlled by the local environmental control module control box 2 or by receiving a stop command from the host computer.

[0090] Preferably, the environmental control module control box 2 has the following handling logic for when the seawater source compression and condensation module 101 malfunctions:

[0091] When only one of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 is running, the environmental control module control box 2 will automatically switch to the other refrigeration compressor to run if it detects that the running refrigeration compressor is overloaded, overpressured or has other faults.

[0092] When the first refrigeration compressor 1101 and the second refrigeration compressor 1102 are running simultaneously, if the environmental control module control box 2 detects faults such as overcurrent, overpressure, or high refrigerant pressure alarm in the first refrigeration compressor 1101 or the second refrigeration compressor 1102, the environmental control module control box 2 will stop the corresponding refrigeration compressor that is malfunctioning and send an alarm signal to the host computer. During this period, the ethylene glycol cooling module 102 will not stop working.

[0093] In an emergency, manual operation can be used to enter the over-control mode, where all protection and program control are canceled, and the first refrigeration compressor 1101 and / or the second refrigeration compressor 1102 can be started manually to operate.

[0094] In this example, the dual-cycle fluorine refrigeration system design configuration with redundancy for key components was implemented in a relatively independent manner, which improved the overall survivability of the module. The software system of the environmental control module control box 2 was integrated with algorithm judgment logic and control logic for corresponding faults, realizing unattended operation of the seawater source compression and condensation module 101 and automatic and rapid response to key faults.

[0095] Example 4

[0096] Based on Example 1, the two ethylene glycol supply circulation pumps 1201 and 1202 of the ethylene glycol cooling module 102 adopt a 1-in-1 standby control mode in automatic operation. The specific control logic is as follows:

[0097] The environmental control module control box 2 is used to determine, based on the cumulative usage time of the first ethylene glycol supply circulation pump 1201 and the second ethylene glycol supply circulation pump 1202, to prioritize starting the first ethylene glycol supply circulation pump 1201 or the second ethylene glycol supply circulation pump 1202 with the shorter cumulative running time each time it is started.

[0098] After the equipment is powered on, the first ethylene glycol supply circulation pump 1201 or the second ethylene glycol supply circulation pump 1202 will not detect the flow and pressure within 10 seconds after starting operation. After 10 seconds, the flow and pressure alarms will be detected. The first ethylene glycol supply circulation pump 1201 or the second ethylene glycol supply circulation pump 1202 will not stop and the alarm signal will be sent to the host computer.

[0099] When the system is running, if the environmental control module control box 2 detects that the first ethylene glycol supply circulation pump 1201 or the second ethylene glycol supply circulation pump 1202 has issued an overload alarm signal, it will automatically switch to start another stopped second ethylene glycol supply circulation pump 1202 or first ethylene glycol supply circulation pump 1201.

[0100] During operation, the first ethylene glycol supply circulation pump 1201 or the second ethylene glycol supply circulation pump 1202 only accepts the stop command issued by the host computer. The seawater source marine integrated server liquid cooling device 1 cannot decide to stop the ethylene glycol supply circulation pump 1201 or 1202 on its own.

[0101] The above operating logic not only improves the automatic and rapid dynamic response to resolve faults during the operation of the ethylene glycol supply circulation pump 1201 or 1202, but also enhances the overall reliability of the equipment.

[0102] Based on Example 2, the ethylene glycol cooling module 102 has two ethylene glycol return filters 1209 and 1210 connected in parallel on the return main pipe, as well as two pairs of electric butterfly valves 1211 and 1212, 1213 and 1214 at the filter inlet and outlet, and pressure sensors 1215 and 1216 at the ethylene glycol return filter inlet and outlet. The third pressure sensor 12155 and the fourth pressure sensor 1216, installed at the inlet and outlet of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210, respectively, monitor the pressure values ​​at both ends of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210, and transmit the data in real time to the environmental control module control box 2. The environmental control module control box 2 obtains the pressure drop value of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210 by subtracting the values ​​at both ends respectively. This value is compared with the recorded initial pressure drop value. When the pressure drop exceeds the allowable threshold, an alarm is triggered to indicate a blockage fault in the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210, and corresponding measures are automatically initiated to address the fault. The specific control mode is as follows:

[0103] When the marine integrated server liquid cooling system 1 is not started, during the initial detection state, the start-up and operation of the marine integrated server liquid cooling system 1 is stopped, an audible and visual alarm is issued, and the cause of the fault is marked on the display screen of the environmental control module control box 2.

[0104] When the marine integrated server liquid cooling system 1 is started, during operation, if the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210 are detected to be clogged, an audible and visual alarm will be triggered after a 2-minute delay to indicate the cloggedness of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210. At the same time, information will be reported to the host computer, and the server operating status will be communicated with the host computer. If the data server is running, all four electric butterfly valves on the inlet and outlet of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210—first electric butterfly valve 1211, second electric butterfly valve 1212, third electric butterfly valve 1213, and fourth electric butterfly valve 1214—will be opened, and the ethylene glycol cooling module 102 will enter the overcurrent operation state to ensure that the flow rate meets the server's operating requirements. Meanwhile, the fault display on screen 204 of the environmental control module control box remains until the host computer issues a shutdown command, at which point the operation of the seawater source marine integrated server liquid cooling system 1 can be stopped and the corresponding components repaired.

[0105] The above design allows for real-time monitoring of the operating status of the first ethylene glycol return filter 1209 and the second ethylene glycol return filter 1210, and ensures that when the server is running, a fault in the first ethylene glycol return filter 1209 or the second ethylene glycol return filter 1210 can be automatically and dynamically resolved.

[0106] Based on Example 1, the pressure sensor 1224 of the supply pipeline system in the constant pressure replenishment and exhaust component transmits the system pipeline pressure to the environmental control module control box 2 in real time. When the ethylene glycol solution in the system decreases due to leakage or other reasons, causing the system pressure to be low, the pipeline system pressure will decrease. At this time, the environmental control module control box 2 will compare the real-time pipeline pressure value of the system pressure sensor 1224 with the set pipeline pressure threshold. If it is lower than the threshold, after a 10-minute delay, the replenishment pump 1221, the first automatic water replenishment valve 1225, and the second automatic water replenishment valve 1226 will be automatically opened to replenish the ethylene glycol solution in the liquid addition tank 1218 into the system pipeline. When the real-time monitored pipeline pressure returns to the threshold... If the pressure exceeds the set threshold, the replenishment pump 1221 will stop and the first automatic water replenishment valve 1225 and the second automatic water replenishment valve 1226 will be closed. If the pipeline pressure falls below the set threshold again within 30 minutes, the environmental control module control box 2 will issue an audible and visual alarm and send a leakage alarm signal to the host computer. At this time, the data server is running, so the equipment will continue to operate without stopping. Normally, when the seawater source marine integrated server liquid cooling device 1 is not running, the environmental control module control box 2 will be powered on periodically. Through the self-checking of the leakage detection rope 9 described in Example 2, when there is liquid leakage at the bottom of the frame box 103, the audible and visual alarm and display device on the control box 2 will indicate that there may be leakage in the internal pipeline, and will send fault information to the host computer. The above design realizes comprehensive automatic monitoring of leakage faults of device 1 and automatic and rapid response to faults during operation.

[0107] In this example, the key function of the ethylene glycol cooling module 102 is to ensure a continuous supply of ethylene glycol coolant to the server to meet its operational requirements. The main critical faults affecting this function of the entire ethylene glycol cooling module 102 fall into three categories: failure of the ethylene glycol supply circulation pump 1201 or 1202, blockage of the ethylene glycol dry pipe filter 1209 or 1210, and leakage of the ethylene glycol coolant pipeline. To address these three types of critical faults, necessary redundancy design was implemented for the key components associated with these faults during the design phase. Sensors and automatic execution components for real-time monitoring of key parameters were also added. The software system of the environmental control module control box 2 integrates algorithm judgment logic and control logic for the corresponding faults, realizing unattended operation of the module and automatic and rapid response to critical faults.

[0108] Example 5

[0109] Based on Example 1, a method for controlling the temperature of the ethylene glycol coolant supplied to the server is also provided. Using the equipment described in Example 1, the specific implementation method of the two sets of internal circulation fluorine refrigeration systems is as follows:

[0110] Step S1: The environmental control module control box 2 is used to collect the temperature values ​​of the liquid supply pipeline outlet temperature sensor 1206 and the return liquid temperature sensor 1207 in real time, as well as the total liquid supply flow rate of the electromagnetic flow sensor 1208 on the return liquid main pipe, and automatically calculate the total load heat. When the load heat is greater than the first preset threshold, such as when the load heat is >10kW, the other set of fluorine refrigeration system of the seawater source compression condensation module 101 is turned on. During operation, when the load heat is detected to be less than or equal to the first preset threshold, and the load heat is ≤10kW for more than 3 minutes, the second set of fluorine refrigeration system of the seawater source compression condensation module 101 can be stopped to ensure that the overall cooling capacity of the device matches the load heat.

[0111] Step S2, the environmental control module control box 2 is used to open the first hot gas bypass valve group in the parallel double hot gas bypass pipeline and the first hot gas bypass valve group 1108 and the first and second hot gas bypass valve group 1109 on the Freon refrigerant pipeline at the outlet of the running scroll vertical first compressor 1101 when the supply liquid temperature is still higher than the set temperature after the above-mentioned fluorine refrigeration system adjustment is completed; or to open the second hot gas bypass valve group in the parallel double hot gas bypass pipeline and the second hot gas bypass valve group 1110 and the second and second hot gas bypass valve group 1111 on the Freon refrigerant pipeline at the outlet of the running second compressor 1102; when the supply liquid temperature is still higher than the set temperature, the first and second hot gas bypass valve groups or the second and second hot gas bypass valve groups are also opened, so that part of the fluorine refrigerant bypasses the plate evaporator and directly enters the inlet of the refrigeration compressor, thereby reducing the heat exchange with the ethylene glycol supply liquid and thus increasing the supply liquid temperature;

[0112] Step S3, the environmental control module control box 2 is used to gradually open the electric bypass valve 1203 between the supply and return liquid mains when the supply liquid temperature is still higher than the set temperature, so that a small amount of high-temperature ethylene glycol return liquid is mixed with low-temperature ethylene glycol supply liquid to appropriately increase the supply liquid temperature. When the temperature of the ethylene glycol solution monitored by the temperature sensor 1206 at the outlet of the supply pipeline is still lower than the temperature required by the data server, the electric bypass valve 1203 can be opened step by step until the difference between the ethylene glycol supply liquid temperature and the set temperature does not exceed ±2℃.

[0113] Through the above-mentioned stepped temperature control logic, the ethylene glycol supply temperature can be set within ±2℃ of the server's heat load range of 10% to 100% under different cooling conditions.

[0114] Example 6

[0115] Based on Example 1, two sets of condensing pressure regulating valves 1112 and 1113 are connected in parallel at the seawater inlet of the shell-and-tube condenser 1103 to regulate the flow rate of cooling seawater entering the condenser 1103 according to the change of condensing pressure. The first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 directly sense the condensing pressure of the fluorinated refrigerant in the shell-and-tube condenser 1103 to change the opening degree of the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113, thereby controlling the flow rate of cooling seawater. When the condensing pressure in the condenser 1103 increases (i.e., the condensing pressure rises), the valve core flow area automatically opens larger, allowing more cooling seawater to enter the condenser 1103, accelerating the condensation rate of the fluorinated refrigerant, and reducing the pressure value in the condenser 1103, returning it to the set value. Conversely, when the condensing pressure decreases, the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 automatically close smaller, reducing the amount of cooling seawater entering the condenser 1103, thereby maintaining the condensing pressure within a certain range. Through this thermal feedback system, regardless of changes in the external seawater temperature, the condensing temperature in the condenser 1103 is controlled within the range of 40℃±2℃.

[0116] Based on Example 2, the first thermal expansion valve 1104 and the second thermal expansion valve 1105, installed on the inlet pipes of the first plate evaporator 1106 and the second evaporator 1107, mainly regulate the flow rate of the refrigerant in the system, control the temperature of the refrigerant in the first evaporator 1106 and the second evaporator 1107, and thus control the evaporation temperature at 12℃±2℃. The heat exchange capacity of a single expansion valve 1104 or 1105 in this device is 18.1kW, and the compression and condensation capacity of a single compressor 1101 or 1102 is approximately 2 / 3 of its range, with a 1 / 3 margin of adjustment capability.

[0117] In this example, by designing and selecting a suitable first thermal expansion valve 1104, the evaporation temperature of the first evaporator 1106 is controlled to fluctuate within a preset effective range; the second thermal expansion valve 1105 controls the evaporation temperature in the second evaporator 1107 to fluctuate within a preset effective range; the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 are selected and arranged in parallel to enhance their ability to regulate the cooling seawater flow, so that the condensing temperature in the condenser 1103 is stabilized within the effective range; thus, the entire seawater source marine integrated server liquid cooling system 1 can operate stably in cooling conditions throughout the year and under global shipping external environmental temperature changes, especially in the wide range of seawater temperature changes from 2℃ to 40℃, meeting the cooling needs of the data server throughout the year.

It provides ethylene glycol coolant to meet the cooling requirements of servers within ship data center compartments.
