Description

Technical Field

[0001] This application relates to the technical field of heat dissipation, and particularly to a cold source device. Background Art

[0002] The current liquid cooling system in data centers usually configures an independent cooling tower, a chiller, a circulating water pump, and a control system. The cooling tower supplies high-temperature coolant to the liquid cooling cabinet or the coolant distribution unit (CDU) to effectively dissipate heat from the data center equipment. With the continuous expansion of data center services and the growth of data volume, the demand for cold sources will also increase continuously. Since devices such as chillers and cooling towers are usually fixed in an independent machine room or on the roof area, they not only occupy a large area but also have a fixed location. Once faced with an increase in cold source demand, it is very likely to encounter the dilemma of insufficient space, and then be forced to consider relocating or reconstructing the cold source facilities, which requires reconfiguring pipelines and control systems, etc., resulting in high transformation costs and the risk of business interruption; and when the cold source demand in the data center is at a low level, the system will still continuously supply cold sources according to the original configuration, causing a double waste of energy and space resources; therefore, it is difficult to meet the requirements of elastic deployment in data centers. Summary of the Invention

[0003] This application provides a cold source device to at least solve the problem that the liquid cooling system in the related art is difficult to meet the requirements of elastic deployment in data centers.

[0004] This application provides a cold source device, including a fixed seat, a cooling device, a liquid supply and circulation device, an inlet pipeline, an outlet pipeline, and a control box; the cooling device is fixed on the fixed seat; the liquid supply and circulation device is connected to the cooling device and fixed on the fixed seat; one end of the inlet pipeline is connected to the liquid supply and circulation device, and the other end is used to be connected to an air-cooled device or a liquid-cooled device; one end of the outlet pipeline is connected to the cooling device, and the other end is used to be connected to an air-cooled device or a liquid-cooled device; the control box is fixed on the cooling device and is provided with a control system; the control system is communicatively connected to both the cooling device and the liquid supply and circulation device.

[0005] Through this application, the cooling device and the liquid supply circulation device are both fixed on the fixed seat, connected to the air-cooled device or the liquid-cooled device through the liquid inlet pipeline, and the liquid outlet pipeline is connected to the air-cooled device or the liquid-cooled device; and a control box is provided on the cooling device, and the control system of the control box is communicatively connected to both the cooling device and the liquid supply circulation device to control the operation of the cooling device and the liquid supply circulation device, realizing the integrated and modular design of the cooling device; when the data center faces an increase in the demand for a cold source, only the number of cold source devices needs to be simply increased and connected to the new devices, then the cold source supply capacity can be expanded, and the operation stability of the original cold source devices will not be affected in this process, ensuring the continuous and stable operation of the data center when the cold source demand changes; when the cold source demand in the data center is at a low level, the redundant cold source devices can be removed, thereby effectively saving energy consumption and space resources and realizing the efficient utilization of resources; therefore, the technical problem that the liquid cooling system is difficult to meet the requirements of elastic deployment of the data center can be solved, the scalability and flexibility of the system are improved, and the technical effect of supporting modular layout and flexible deployment according to actual needs is achieved.

[0011] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0012] An embodiment of the present application provides a cold source device, and the device will be described in detail in combination with the structure and working principle of the cold source device.

[0013] According to an embodiment of the present invention, there is provided a cold source device, such as Figure 1 and Figure 2As shown, the cold source device includes a fixed seat 1, a cooling device 2, a liquid supply circulation device 3, a liquid inlet pipeline 4, a liquid outlet pipeline 5 and a control box 6; the cooling device 2 is fixed on the fixed seat 1; the liquid supply circulation device 3 is connected to the cooling device 2 and fixed on the fixed seat 1; one end of the liquid inlet pipeline 4 is connected to the liquid supply circulation device 3, and the other end is used to connect with an air cooling device or a liquid cooling device; one end of the liquid outlet pipeline 5 is connected to the cooling device 2, and the other end is used to connect with an air cooling device or a liquid cooling device; the control box 6 is fixed on the cooling device 2, and is provided with a control system; the control system is communicatively connected with the cooling device 2 and the liquid supply circulation device 3.

[0014] Through the present application, the cooling device 2 and the liquid supply circulation device 3 are both fixed on the fixing seat 1, connected to the air cooling device or the liquid cooling device through the liquid inlet pipeline 4, and connected to the air cooling device or the liquid cooling device through the liquid outlet pipeline 5, and a control box 6 is provided on the cooling device 2, and the control system of the control box 6 is communicated with the cooling device 2 and the liquid supply circulation device 3 to control the operation of the cooling device 2 and the liquid supply circulation device 3, thereby realizing the integration and modular design of the cooling device 2; when the data center faces an increase in the demand for cold sources, it is only necessary to simply increase the number of cold source devices and connect them to the newly added equipment to expand the cold source supply capacity, and this process will not cause any impact on the operating stability of the original cold source device, thereby ensuring the continuous and stable operation of the data center when the cold source demand changes; when the cold source demand of the data center is at a low level, the redundant cold source devices can be removed, thereby effectively saving energy consumption and space resources, and realizing efficient utilization of resources; therefore, the technical problem that the liquid cooling system is difficult to meet the needs of flexible deployment of the data center can be solved, the scalability and flexibility of the system can be improved, and the technical effect of supporting modular layout and flexible deployment according to actual needs can be achieved.

[0015] In a specific implementation, the control box 6 is fixed to a side of the cooling device 2 away from the liquid supply circulation device 3 and is responsible for power supply and control of the entire device.

[0016] In a specific implementation, the fixing base 1 is an integrated base formed by splicing C-shaped steel and the like.

[0017] In one embodiment, a condenser is further included, and the liquid inlet pipeline 4 is connected to the air cooling device through the condenser; the liquid outlet pipeline 5 is connected to the air cooling device through the condenser.

[0018] In an actual cooling system, the cold source device undertakes the important task of providing coolant at appropriate temperatures for different devices. It is necessary to supply high-temperature coolant above 30°C to liquid-cooled devices and low-temperature coolant in the range of 7 - 15°C to air-cooled devices. By setting up a condenser, the high-temperature coolant discharged from the liquid outlet pipeline 5 will first flow through the condenser, where it undergoes a cooling process to reduce its temperature to the low-temperature range of 7 - 15°C required by the air-cooled devices. Then, the cooled coolant enters the air-cooled devices. This can not only achieve the supply of high-temperature coolant to liquid-cooled devices but also the supply of low-temperature coolant to air-cooled devices, realizing a liquid-air homologous liquid supply mode. Through a set of equipment and a supporting control system, the control of the cold source supply for air-cooled devices and liquid-cooled devices can be achieved, simplifying the system design architecture, optimizing the control strategy, enhancing the reliability and energy efficiency of the system, and reducing equipment investment and maintenance costs.

[0019] In a specific implementation manner, one or more first liquid outlet branches can be set at the liquid outlet end of the liquid outlet pipeline 5 according to actual requirements, and one or more first liquid inlet branches can be set at the liquid inlet end of the liquid inlet pipeline 4. The first liquid inlet branches correspond to the first liquid outlet branches one by one, and the first liquid inlet branch and the corresponding first liquid outlet branch are connected to the air-cooled device, or the first liquid inlet branch and the corresponding first liquid outlet branch are connected to the liquid-cooled device. It is possible to achieve simultaneous liquid supply to multiple air-cooled devices, or simultaneous liquid supply to multiple liquid-cooled devices, or simultaneous liquid supply to multiple air-cooled devices and multiple liquid-cooled devices.

[0020] In a specific implementation manner, when the liquid inlet pipeline 4 and the liquid outlet pipeline 5 are connected to the liquid-cooled device, they can be directly connected to liquid-cooled devices such as liquid-cooled cabinets; or the liquid inlet pipeline 4 and the liquid outlet pipeline 5 are connected to the cold distribution unit (CDU) to provide a cold source for the primary side of the cold distribution unit, and the secondary side of the cold distribution unit is connected to the liquid-cooled cabinet.

[0021] In a specific implementation manner, the air-cooled device can be an in-row air conditioner.

[0022] In an embodiment, it further includes a temperature detection mechanism 7, which is arranged on the liquid outlet pipeline 5 and is communicatively connected to the control system.

[0023] Since the control system is communicatively connected to the temperature detection mechanism 7, the liquid outlet temperature of the liquid outlet pipeline 5 can be precisely regulated by controlling the cooling device 2 and the liquid supply circulation device 3 according to the liquid outlet temperature detected by the temperature detection mechanism 7 to ensure that it always remains stable within the target temperature range.

[0024] In a specific implementation manner, the temperature detection mechanism 7 is a temperature sensor.

[0025] In an embodiment, such as Figure 4As shown in the figure, the liquid supply circulation device 3 includes a box body 301, a circulation water pump 302, a connecting pipeline 303, and a temperature balance component 304; the box body 301 is fixed on the fixed seat 1; the circulation water pump 302 is arranged in the box body 301; both ends of the connecting pipeline 303 are respectively connected to the cooling device 2 and the circulation water pump 302; the temperature balance component 304 is arranged in the box body 301 to connect the connecting pipeline 303 and the liquid outlet pipeline 5 and is communicatively connected to the control system.

[0026] Since the temperature of the coolant in the connecting pipeline 303 is relatively high, the control system is communicatively connected to the temperature balance component 304. According to the liquid outlet temperature detected by the temperature detection mechanism 7, the control system can control the on-off of the liquid outlet pipeline 5 and the connecting pipeline 303 by controlling the temperature balance component 304. By adjusting the flow path and flow rate of the coolant, the temperature of the coolant in the liquid outlet pipeline 5 can be changed, which helps to effectively adjust the liquid outlet temperature and finally achieve the purpose of maintaining the liquid outlet temperature stable at the liquid outlet target temperature.

[0027] In a specific embodiment, when the fan 202 in the cooling device 2 reaches the lower limit speed and the liquid outlet temperature detected by the temperature detection mechanism 7 is less than the difference between the liquid outlet target temperature and the first dead band threshold value, continuous monitoring and waiting for the first preset time are carried out. If the temperature state always meets the above conditions, the control system controls the temperature balance component 304 to connect the liquid outlet pipeline 5 and the connecting pipeline 303. Since the temperature of the coolant in the connecting pipeline 303 is relatively high, after the liquid outlet pipeline 5 and the connecting pipeline 303 are connected, the relatively high-temperature coolant in the connecting pipeline 303 enters the liquid outlet pipeline 5, increasing the temperature of the coolant in the liquid outlet pipeline 5 and helping to raise the temperature of the coolant in the liquid outlet pipeline 5 to the liquid outlet target temperature. When the liquid outlet temperature detected by the temperature detection mechanism 7 is higher than the sum of the liquid outlet target temperature and the first dead band threshold value, continuous monitoring and waiting for the first preset time are carried out. If the temperature state always meets the above conditions, the control system controls the temperature balance component 304 to disconnect the liquid outlet pipeline 5 and the connecting pipeline 303.

[0028] Specifically, by setting the first differential threshold value, it is possible to avoid the frequent start and stop of the temperature balancing component 304 due to small fluctuations in the temperature near the target liquid outlet temperature, ensuring the stability and reliability of the system operation and reducing the losses caused by frequent actions of the equipment. By introducing the delay mechanism of the first preset time, it is possible to effectively avoid the frequent activation of the temperature balancing component 304 due to short-term temperature fluctuations or accidental over-standard, thereby while ensuring that the system responds reasonably to changes in the ambient temperature, reducing unnecessary actions, prolonging the service life of the equipment and optimizing the overall operation efficiency. Specifically, there are no restrictions on the target liquid outlet temperature, the first preset time, and the first differential threshold value, and the target liquid outlet temperature, the first preset time, and the first differential threshold value can be adjusted according to the actual on-site situation; the target liquid outlet temperature can be 40°C or above; the first preset time can be 300 seconds.

[0029] In a specific embodiment, the box body 301 includes a first side plate 3011, a second side plate 3012, a third side plate 3013, and a fourth side plate 3014 that are sequentially connected end to end in the circumferential direction, and a top plate 3015 connected to the first side plate 3011, the second side plate 3012, the third side plate 3013, and the fourth side plate 3014, which can protect the components inside the box body 301. The first side plate 3011 and the second side plate 3012 are oppositely arranged, and the first side plate 3011 is arranged on the side of the fourth side plate 3014 away from the cooling device 2; a maintenance door 3016 is provided on the first side plate 3011 to facilitate the maintenance of the components inside the box body 301; a first mounting hole 30111 is provided on the first side plate 3011, and the liquid inlet pipeline 4 is connected to the circulating water pump 302 and the air-cooling device or the liquid-cooling device through the first mounting hole 30111; a second mounting hole is reserved on the second side plate 3012, and the connecting pipeline 303 is connected to the circulating water pump 302 and the cooling device 2 through the second mounting hole; a third mounting hole is also provided on the second side plate 3012, and a fourth mounting hole 30112 is also provided on the first side plate 3011. One end of the liquid outlet pipeline 5 is connected to the cooling device 2, and the other end is connected to the air-cooling device or the liquid-cooling device through the third mounting hole and the fourth mounting hole 30112 in sequence.

[0030] In one embodiment, as Figure 5 shown, the temperature balancing component 304 includes a first bypass pipe 3041 and a first bypass valve 3042; the first bypass pipe 3041 is arranged inside the box body 301, and both ends are respectively connected to the liquid outlet pipeline 5 and the connecting pipeline 303; the first bypass valve 3042 is arranged on the first bypass pipe 3041 and is communicatively connected to the control system.

[0031] In a specific embodiment, the control system controls the on-off of the first bypass pipe 3041 by controlling the first bypass valve 3042 according to the outlet temperature of the mixed liquid detected by the temperature detection mechanism 7. When it is necessary to connect the liquid outlet pipeline 5 and the connection pipeline 303, the control system performs the first proportional-integral-derivative calculation according to the outlet temperature of the mixed liquid detected by the temperature detection mechanism 7, and controls the valve opening of the first bypass valve 3042 according to the output value of the first proportional-integral-derivative calculation, so as to control the coolant flow rate from the connection pipeline 303 into the liquid outlet pipeline 5 until the outlet temperature detected by the temperature detection mechanism 7 stabilizes at the outlet target temperature. When it is necessary to disconnect the liquid outlet pipeline 5 and the connection pipeline 303, the control system controls the first bypass valve 3042 to close.

[0032] In a specific embodiment, the actuator controlling the first bypass valve 3042 is always powered on to ensure timely response.

[0033] In a specific embodiment, the first bypass valve 3042 includes power-off self-holding and communication-loss self-holding functions. When the control system suddenly loses power, the first bypass valve 3042 can automatically maintain its current working state by virtue of its power-off self-holding function, avoiding abnormal actions caused by power interruption; when a fault occurs in the communication link between the first bypass valve 3042 and the control system and the communication signal is lost, the communication-loss self-holding function of the first bypass valve 3042 will be immediately activated to ensure that the first bypass valve 3042 continues to operate stably according to the instructions and preset parameters before the communication interruption, thus effectively ensuring the reliability and safety of the entire system.

[0034] In a specific embodiment, during the period when the control system controls the first bypass valve 3042 to be in the open state, the fan 202 always maintains the lower limit speed; during this period, if the outlet temperature detected by the temperature detection mechanism 7 still fails to reach the outlet target temperature, the fan 202 is turned off.

[0035] In a specific embodiment, as Figure 6 shown, the liquid outlet pipeline 5 includes a first pipeline and a second pipeline. The first pipeline is connected to the cooling device 2, and the second pipeline is connected to the air-cooling device or the liquid-cooling device; the first bypass valve 3042 is an electric three-way valve, and the first pipeline, the second pipeline and the first bypass pipe 3041 are connected through the first bypass valve 3042.

[0036] In one embodiment, as Figure 6As shown in the figure, the liquid supply circulation device 3 includes a box body 301, a circulation water pump 302, a pressure balance component 305, and a first pressure detection mechanism 306: The box body 301 is fixed on the fixed seat 1; The circulation water pump 302 is arranged in the box body 301 and is connected to the liquid inlet pipeline 4; The pressure balance component 305 is arranged in the box body 301 and connects the liquid inlet pipeline 4 and the liquid outlet pipeline 5: The first pressure detection mechanism 306 is arranged in the box body 301 and is installed on the liquid outlet pipeline 5; The control system is communicatively connected to both the pressure balance component 305 and the first pressure detection mechanism 306.

[0037] In a specific embodiment, the control system controls the on-off of the liquid inlet pipeline 4 and the liquid outlet pipeline 5 by controlling the pressure balance component 305 according to the pressure data detected by the first pressure detection mechanism 306.

[0038] In a specific embodiment, the type of the first pressure detection mechanism 306 is not limited, and the first pressure detection mechanism 306 can be a pressure gauge, a pressure sensor, etc.

[0039] Since the control system is communicatively connected to both the pressure balance component 305 and the first pressure detection mechanism 306, it can control the on-off of the liquid inlet pipeline 4 and the liquid outlet pipeline 5 by controlling the pressure balance component 305 according to the pressure data detected by the first pressure detection mechanism 306. By adjusting the flow path and flow rate of the coolant, the pressure of the liquid outlet pipeline 5 can be changed, which helps to effectively regulate the pressure of the liquid outlet pipeline 5 and maintain the pressure of the liquid outlet pipeline 5 stably at the liquid outlet target pressure, ensuring that the pressure in the entire system is in a balanced state.

[0040] In a specific embodiment, when the circulation water pump 302 reaches the minimum rotation speed and the pressure data detected by the first pressure detection mechanism 306 is higher than the liquid outlet target pressure, continuously monitor and wait for the second preset time. If the pressure state always meets the above conditions, the control system controls the pressure balance component 305 to connect the liquid outlet pipeline 5 and the liquid inlet pipeline 4, and drains the liquid in the liquid outlet pipeline 5 into the liquid inlet pipeline 4 to reduce the pressure of the liquid outlet pipeline 5, which helps to reduce the pressure of the liquid outlet pipeline 5 to the liquid outlet target pressure. When the pressure data detected by the first pressure detection mechanism 306 is less than the liquid outlet target pressure, continuously monitor and wait for the second preset time. If the pressure state always meets the above conditions, the control system controls the pressure balance component 305 to disconnect the liquid outlet pipeline 5 and the liquid inlet pipeline 4. By introducing the delay mechanism of the second preset time, it can effectively avoid the frequent opening of the pressure balance component 305 caused by short-term pressure fluctuations or accidental over-standard, thereby ensuring that the system responds reasonably to pressure changes while reducing unnecessary actions, extending the service life of the equipment and optimizing the overall operation efficiency. Specifically, the liquid outlet target pressure is not limited, and the liquid outlet target pressure can be adjusted according to the actual on-site situation.

[0041] In one embodiment, as Figure 6 shown, the pressure balance assembly 305 includes a second bypass pipe 3051 and a second bypass valve 3052; the second bypass pipe 3051 is disposed within the cabinet 301 and is connected at both ends to the liquid outlet pipeline 5 and the liquid inlet pipeline 4 respectively; the second bypass valve 3052 is disposed on the second bypass pipe 3051; the control system is communicatively connected to the second bypass valve 3052.

[0042] In a specific embodiment, the control system controls the on-off of the second bypass pipe 3051 by controlling the second bypass valve 3052 according to the pressure data detected by the first pressure detection mechanism 306. When it is necessary to connect the liquid outlet pipeline 5 and the liquid inlet pipeline 4, the control system performs a second proportional-integral-derivative calculation based on the pressure data detected by the pressure detection mechanism, and controls the valve opening of the second bypass valve 3052 according to the output value of the second proportional-integral-derivative calculation, so as to control the flow rate of the liquid flowing from the liquid outlet pipeline 5 into the liquid inlet pipeline 4 until the pressure data detected by the pressure detection mechanism stabilizes at the liquid outlet target pressure. When it is necessary to disconnect the liquid outlet pipeline 5 and the liquid inlet pipeline 4, the control system controls the second bypass valve 3052 to close.

[0043] In a specific embodiment, the actuator for controlling the second bypass valve 3052 is always in a powered state to ensure timely response.

[0044] In a specific embodiment, during the period when the control system controls the first bypass valve 3042 to be in an open state, the circulating water pump 302 always maintains the minimum rotational speed.

[0045] In a specific embodiment, two first manual valves 3053 are further provided on the second bypass pipe 3051, and the second bypass valve 3052 is disposed between the two first manual valves 3053.

[0046] In one embodiment, the liquid supply circulation device 3 further includes a filter 307, and the filter 307 is connected to the liquid outlet pipeline 5.

[0047] When the coolant is transported to the air-cooling device and the liquid-cooling device via the liquid outlet pipeline 5, it will first flow through the filter 307. During this process, various impurities mixed in the coolant, such as particulate matter, rust slag, etc., will be effectively intercepted and filtered, thereby preventing these impurities from entering the air-cooling device and the liquid-cooling device together with the coolant, and preventing equipment failures, performance degradation, etc. caused by impurity accumulation or wear, and ensuring that the air-cooling device and the liquid-cooling device always operate efficiently in a clean and good coolant environment.

[0048] In a specific embodiment, the filter 307 is a Y-type filter 307.

[0049] In one embodiment, the liquid supply circulation device 3 further includes a second pressure detection mechanism 308, and the second pressure detection mechanism 308 is connected to the liquid outlet pipeline 5; the filter 307 is arranged between the first pressure detection mechanism 306 and the second pressure detection mechanism 308; the control system is communicatively connected to the second pressure detection mechanism 308.

[0050] In a specific embodiment, the control system can judge the state of the filter 307 according to the pressure difference between the first pressure detection mechanism 306 and the second pressure detection mechanism 308. When the pressure difference between the first pressure detection mechanism 306 and the second pressure detection mechanism 308 is higher than the pressure alarm value, the control system outputs a dirty blockage alarm for the filter 307. Specifically, there is no limit to the pressure alarm value, and the pressure alarm value can be adjusted according to the actual situation on site; the pressure alarm value can be 1 bar.

[0051] In a specific embodiment, the type of the second pressure detection mechanism 308 is not limited, and the second pressure detection mechanism 308 can be a pressure gauge, a pressure sensor, etc.

[0059] In one embodiment, the liquid supply circulation device 3 further includes a constant pressure deaeration mechanism 311. The constant pressure deaeration mechanism 311 is disposed in the box body 301, installed on the liquid inlet pipeline 4, and located on the side of the third pressure detection mechanism 309 away from the circulating water pump 302.

[0060] By providing the constant pressure deaeration mechanism 311 on the liquid inlet pipeline 4, the gas dissolved or entrained in the coolant entering the system can be removed, and the functions of constant pressure and pressure relief can also be achieved, maintaining the stability and safety of the pressure in the pipeline.

[0061] In a specific embodiment, the constant pressure deaeration mechanism 311 includes a deaeration tank 3111, a constant pressure tank 3112, and a safety valve 3113. The deaeration tank is connected to the liquid inlet pipeline 4; the constant pressure tank 3112 and the safety valve 3113 are connected to the top of the deaeration tank 3111.

[0063] In a specific embodiment, the coolant from the air-cooling device and the liquid-cooling device enters the liquid inlet pipeline 4, passes through the butterfly valve, enters the degassing tank 3111 for degassing and buffering, then enters the circulation water pump 302. After being boosted by the circulation water pump 302, it enters the heat exchanger 201 through the connecting pipeline 303 for heat exchange. After the heat exchange is completed, it enters the liquid outlet pipeline 5, flows through structures such as the first bypass valve 3042, the filter 307, and the flowmeter, and then enters the air-cooling device and the liquid-cooling device again.

[0064] In a specific embodiment, the system constant pressure of the constant pressure degassing mechanism 311 is 1 bar.

[0065] In a specific embodiment, a flowmeter is provided on the liquid outlet pipeline 5 to measure whether the liquid flow rate in the system meets the requirements.

[0066] In one embodiment, as Figure 7 and Figure 8 shown, the liquid supply and circulation device 3 further includes a liquid storage mechanism 312. The liquid storage mechanism 312 is arranged in the box body 301 and includes a liquid storage tank 3121, a first liquid replenishing pipe 3122, and a liquid replenishing pump 3123. The liquid storage tank 3121 is fixed on the fixing seat 1 and is located below the constant pressure degassing mechanism 311. Both ends of the first liquid replenishing pipe 3122 are respectively connected to the liquid storage tank 3121 and the constant pressure degassing mechanism 311. The liquid replenishing pump 3123 is arranged on the first liquid replenishing pipe 3122 and is communicatively connected to the control system.

[0067] In a specific embodiment, the control system controls the start and stop of the liquid replenishing pump 3123 according to the pressure data detected by the third pressure detection mechanism 309. When the pressure data detected by the third pressure detection mechanism 309 is lower than the first pressure value, it continuously monitors and waits for the third preset time. If the pressure state always meets the above conditions, the control system controls the liquid replenishing pump 3123 to start, and replenishes the constant pressure degassing mechanism 311 through the first liquid replenishing pipe 3122. When the pressure data detected by the third pressure detection mechanism 309 reaches the second pressure value, the control system controls the liquid replenishing pump 3123 to close and stops replenishing the constant pressure degassing mechanism 311. By introducing the delay mechanism of the third preset time, it can effectively avoid the frequent start of the liquid replenishing pump 3123 caused by short-term pressure fluctuations or accidental over-standard, thereby while ensuring that the system responds reasonably to pressure changes, reducing unnecessary actions, extending the service life of the equipment, and optimizing the overall operation efficiency. Specifically, the first pressure value is lower than the second pressure value; there are no restrictions on the first pressure value, the second pressure value, and the third preset time, and the first pressure value, the second pressure value, and the third preset time can be adjusted according to the actual on-site situation; the first pressure value can be 0.8 bar; the second pressure value can be 1.5 bar; the third preset time can be 300 seconds.

[0068] In one embodiment, the liquid supply circulation device 3 further includes a liquid storage mechanism 312. The liquid storage mechanism 312 is arranged in the box body 301 and includes a liquid storage tank 3121, a liquid discharge pipe and a first liquid discharge valve. The liquid storage tank 3121 is fixed on the fixed seat 1 and is located below the constant pressure degassing mechanism 311. The two ends of the liquid discharge pipe are respectively connected to the liquid storage tank 3121 and the constant pressure degassing mechanism 311. The first liquid discharge valve is arranged on the liquid discharge pipe and is communicatively connected to the control system.

[0069] In a specific embodiment, the control system controls the on-off of the liquid discharge pipe by controlling the first liquid discharge valve according to the pressure data of the first pressure detection mechanism 306. When the pressure data detected by the third pressure detection mechanism 309 is higher than the sum of the second pressure value and the second dead band threshold, the control system controls the first liquid discharge valve to open, and discharges the coolant in the constant pressure degassing mechanism 311 to the liquid storage tank 3121 through the liquid discharge pipe. When the pressure data detected by the third pressure detection mechanism 309 is less than or equal to the second pressure value, the control system controls the first liquid discharge valve to close. Specifically, by setting the second dead band threshold, it is possible to avoid the first liquid discharge valve from opening frequently due to small fluctuations in pressure near the second pressure value, ensuring the stability and reliability of the system operation, and reducing the losses caused by frequent actions of the equipment. There is no limit to the second dead band threshold, and the second dead band threshold can be adjusted according to the actual situation on site; the second dead band threshold can be 0.3 bar.

[0070] In a specific embodiment, both the first liquid replenishing pipe 3122 and the liquid discharge pipe are connected to the degassing tank 3111.

[0071] In a specific embodiment, the first liquid discharge valve is an electromagnetic valve.

[0072] In one embodiment, a liquid level detection mechanism is provided in the liquid storage tank 3121, and the liquid level detection mechanism is communicatively connected to the control system.

[0073] In a specific embodiment, the liquid level detection mechanism includes a first liquid level sensor and a second liquid level sensor. The first liquid level sensor is arranged below the second liquid level sensor. When the liquid level in the liquid storage tank 3121 is lower than the first liquid level sensor, the control system prompts that the liquid volume in the liquid storage tank 3121 is too low and external replenishment to the liquid storage tank 3121 is required. When the liquid level in the liquid storage tank 3121 is higher than the second liquid level sensor, the control system prompts that the liquid volume in the liquid storage tank 3121 meets the standard and stops continuing to replenish the liquid storage tank 3121.

[0074] In a specific embodiment, when the liquid level in the liquid storage tank 3121 is lower than the first liquid level sensor, the control system prompts that the liquid volume in the liquid storage tank 3121 is too low, and the control system controls the liquid replenishing pump 3123 to close and stops the automatic liquid replenishment to the constant pressure degassing mechanism 311.

[0075] In a specific embodiment, a manual liquid addition button is provided on the manual operation interface of the control box 6; the external liquid addition to the liquid storage tank 3121 is controlled by the manual liquid addition button, and at this time, the control system controls both the liquid addition pump 3123 and the first drain valve to be in an open state; when the pressure data detected by the third pressure detection mechanism 309 reaches the second pressure value and the liquid level in the liquid storage tank 3121 is higher than the second liquid level sensor, the control system automatically controls the liquid addition pump 3123 and the solenoid valve to close and automatically exits the manual liquid addition mode.

[0076] In a specific embodiment, a third liquid addition pipe and a discharge pipe are provided on the liquid storage tank 3121; a fifth mounting hole 30113 and a sixth mounting hole 30114 are further provided on the first side plate 3011; one end of the third liquid addition pipe is connected to the liquid storage tank 3121, and the other end passes through the fifth mounting hole 30113 and is connected to an external pipeline; one end of the discharge pipe is connected to the liquid storage tank 3121, and the other end passes through the sixth mounting hole 30114 and is connected to an external pipeline.

[0077] In one embodiment, the liquid supply and circulation device 3 further includes a heating mechanism, which is arranged in the box body 301, installed on the liquid outlet pipeline 5, and is communicatively connected to the control system.

[0078] In a specific embodiment, the control system controls the start and stop of the heating mechanism according to the liquid outlet temperature detected by the temperature detection mechanism 7. When the control system controls the first bypass valve 3042 to be fully opened and the liquid outlet temperature detected by the temperature detection mechanism 7 is less than the difference between the liquid outlet target temperature and the first dead band threshold, the control system controls the heating mechanism to start and heat the liquid in the liquid outlet pipeline 5. When the control system controls the first bypass valve 3042 to be in a closed state and the liquid outlet temperature detected by the temperature detection mechanism 7 is greater than the sum of the liquid outlet target temperature and the first dead band threshold, continuously monitor and wait for the first preset time. If the temperature state always meets the above conditions, the control system controls the heating mechanism to close.

[0079] In one embodiment, the cooling device 2 includes a heat exchanger 201 and a fan 202; the heat exchanger 201 is fixed on the fixed seat 1 and is connected to the liquid supply and circulation device 3 and the liquid outlet pipeline 5; the fan 202 is fixed on the top of the heat exchanger 201 and is communicatively connected to the control system.

[0080] In a specific embodiment, the control system controls the rotational speed of the blower 202 according to the liquid outlet temperature detected by the temperature detection mechanism 7. When the liquid outlet temperature detected by the temperature detection mechanism 7 is greater than or equal to the first temperature value and less than or equal to the second temperature value, the control system performs a fifth proportional-integral-derivative calculation based on the liquid outlet temperature detected by the temperature detection mechanism 7, and controls the rotational speed of the blower 202 according to the output value of the fifth proportional-integral-derivative calculation until the liquid outlet temperature detected by the temperature detection mechanism 7 stabilizes at the liquid outlet target temperature. When the liquid outlet temperature detected by the temperature detection mechanism 7 is greater than the second temperature value, the control system controls the blower 202 to reach the upper limit rotational speed; when the liquid outlet temperature detected by the temperature detection mechanism 7 is less than or equal to the third temperature value, the fifth proportional-integral-derivative calculation is resumed, and the rotational speed of the blower 202 is controlled according to the output value of the fifth proportional-integral-derivative calculation. When the liquid outlet temperature detected by the temperature detection mechanism 7 is less than the first temperature value, the control system controls the blower 202 to reach the lower limit rotational speed, continuously monitors and waits for the fourth preset time. If the temperature state always meets the above conditions and the control system controls the first bypass valve 3042 to be fully opened, the control system controls the blower 202 to be fully closed; when the liquid outlet temperature detected by the temperature detection mechanism 7 is greater than or equal to the fourth temperature value, the fifth proportional-integral-derivative calculation is resumed, and the rotational speed of the blower 202 is controlled according to the output value of the fifth proportional-integral-derivative calculation.

[0081] Specifically, by introducing the delay mechanism of the fourth preset time, it can effectively avoid the frequent shutdown of the blower 202 controlled by the control system due to short-term temperature fluctuations or accidental over-standard, thereby while ensuring that the system makes a reasonable response to environmental temperature changes, reducing unnecessary actions, prolonging the service life of the equipment and optimizing the overall operation efficiency.

[0082] Specifically, the first temperature value is less than the fourth temperature value, the fourth temperature value is less than the third temperature value, the third temperature value is less than the second temperature value, the third temperature value is the difference between the second temperature value and the third deadband threshold value, and the fourth temperature value is the sum of the first temperature value and the third deadband threshold value. Through the setting of the third deadband threshold value, it can avoid the frequent control of the blower 202 due to small fluctuations in the temperature near the first temperature value or the second temperature value, ensuring the stability and reliability of the system operation, and reducing the losses caused by the frequent actions of the equipment.

[0083] Specifically, the target temperature of the liquid outlet is between the fourth temperature value and the third temperature value. There are no restrictions on the third hysteresis threshold value, the first temperature value, the second temperature value, the third temperature value, and the fourth temperature value. The third hysteresis threshold value, the first temperature value, the second temperature value, the third temperature value, and the fourth temperature value can be adjusted according to the actual on-site situation; the third hysteresis threshold value can be 2°C; the first temperature value can be 25°C, the second temperature value can be 45°C, the third temperature value can be 43°C, the fourth temperature value can be 27°C, and the target temperature of the liquid outlet can be 40°C.

[0084] Specifically, the upper limit speed of the fan 202 is higher than the lower limit speed; there are no restrictions on the upper limit speed and the lower limit speed of the fan 202, and the upper limit speed and the lower limit speed of the fan 202 can be adjusted according to the actual on-site situation; the upper limit speed of the fan 202 can be 90% of the rated speed, and the lower limit speed of the fan 202 can be 10% of the rated speed.

[0085] In one embodiment, the cooling device 2 includes a heat exchanger 201, a wet curtain 203, and a spraying system 204; the heat exchanger 201 is fixed on the fixed seat 1 and is connected to the liquid supply circulation device 3 and the liquid outlet pipeline 5; the wet curtain 203 is arranged outside the heat exchanger 201; the spraying system 204 is in communication connection with the control system.

[0086] By arranging the wet curtain 203 on the side of the heat exchanger 201, the air first passes through the wet curtain 203 and then passes through the heat exchanger 201 to exchange heat with the coolant in the heat exchanger 201, thereby cooling the coolant in the heat exchanger 201; the control system controls the spraying system 204 to spray liquid on the wet curtain 203 according to the outdoor ambient temperature data and the liquid outlet temperature of the temperature detection mechanism 7. When the outdoor ambient temperature is relatively high and the liquid outlet temperature is also relatively high, it is necessary to further enhance the refrigeration effect of the cooling device 2. At this time, the control system controls the spraying system 204 to spray liquid on the wet curtain 203, so that the wet curtain 203 is wetted and has sufficient moisture, which can fully absorb the heat in the air for evaporation and heat dissipation, reduce the ambient temperature around the heat exchanger 201, improve the heat dissipation efficiency of the heat exchanger 201, and improve the refrigeration effect; when the outdoor ambient temperature is relatively low, at this time the ambient temperature around the heat exchanger 201 is also relatively low, there is no need to cool the air around the heat exchanger 201 again, preventing the temperature of the liquid flowing out of the heat exchanger 201 from being too low and avoiding reheating the liquid in the liquid outlet pipeline 5 to reach the preset value. Therefore, the control system controls the spraying system 204 to stop spraying liquid on the wet curtain 203, achieving the effect of energy conservation and consumption reduction.

[0087] In a specific implementation manner, by arranging the wet curtain 203 and the spraying system 204, the air temperature around the heat exchanger 201 can be reduced by 3°C to 10°C.

[0088] In a specific embodiment, when the outdoor ambient temperature is greater than the first target temperature and the water outlet temperature detected by the temperature detection mechanism 7 is greater than the liquid outlet target temperature, continuous monitoring is carried out and the fifth preset time is waited. If the temperature state always meets the above conditions, the control system controls the spraying system 204 to spray liquid onto the wet curtain 203. When the outdoor ambient temperature is less than the difference between the first target temperature and the fourth deadband threshold, continuous monitoring is carried out and the fifth preset time is waited. If the temperature state always meets the above conditions, the control system controls the spraying system 204 to stop spraying liquid onto the wet curtain 203. By introducing the delay mechanism of the fifth preset time, it can effectively avoid the frequent start and stop of the spraying system 204 caused by short-term temperature fluctuations or accidental over-standard, thereby while ensuring that the system makes a reasonable response to environmental temperature changes, reducing unnecessary actions, prolonging the service life of the equipment and optimizing the overall operation efficiency. By setting the fourth deadband threshold, it can avoid the frequent start and stop of the spraying system 204 caused by small fluctuations of the temperature near the first target temperature, ensuring the stability and reliability of the system operation, and reducing the loss of the equipment caused by frequent actions. Specifically, there is no limit to the first target temperature, and the first target temperature can be adjusted according to the actual situation on site; the first target temperature can be 33°C.

[0089] Specifically, the heat exchanger 201 is an air-cooled finned heat exchanger 201, and the fan 202 is a variable-frequency fan 202.

[0090] Specifically, the heat exchanger 201 adopts a V-shaped design, which can increase the heat exchange area.

[0091] In a specific embodiment, two groups of second liquid inlet branches 2011 are provided at the liquid inlet end of the heat exchanger 201, and both groups of second liquid inlet branches 2011 are connected to the liquid outlet end of the connecting pipeline 303; two groups of second liquid outlet branches 2012 are provided at the liquid outlet end of the heat exchanger 201, and both groups of second liquid outlet branches 2012 are connected to the liquid inlet end of the liquid outlet pipeline 5.

[0092] In an embodiment, a switch button is provided on the control box 6, and the switch button controls the on-off of the communication connection between the control system and the spraying system 204.

[0093] By setting a switch button to control the on / off of the communication connection between the control system and the spraying system 204. When it is in a season with a relatively high outdoor ambient temperature, since the outdoor ambient temperature is relatively high, it is necessary to cool the area around the heat exchanger 201 through the spraying system 204. The control system and the spraying system 204 can be connected by pressing the switch button to realize the communication connection between the control system and the spraying pump 2043, and the control system can control the spraying system 204 to spray the cooling liquid onto the wet curtain 203 according to the outdoor ambient temperature data and the liquid outlet temperature of the temperature detection mechanism 7. When it is in a season with a relatively low outdoor temperature, since the outdoor ambient temperature is relatively low, there is no need to cool the air around the heat exchanger 201 at this time. Therefore, the control system and the spraying system 204 can be disconnected by pressing the switch button to save power consumption.

[0094] In one embodiment, the spraying system 204 includes a spraying pipeline 2041, a spraying liquid tank 2042, and a spraying pump 2043. The spraying pipeline 2041 is arranged above the wet curtain 203, and nozzles are provided on the spraying pipeline 2041. The top of the spraying liquid tank 2042 is provided with an opening, and it is arranged below the wet curtain 203 and fixed on the fixing seat 1. The spraying pump 2043 is arranged between the spraying liquid tank 2042 and the heat exchanger 201 and fixed on the fixing seat 1. It is connected to both the spraying liquid tank 2042 and the spraying pipeline 2041. The spraying pump 2043 is in communication connection with the control system.

[0095] In a specific implementation manner, the control system controls the start and stop of the spraying pump 2043 according to the outdoor ambient temperature data and the liquid outlet temperature of the temperature detection mechanism 7.

[0096] Since the top of the spraying liquid tank 2042 is provided with an opening and it is arranged below the wet curtain 203, when there is too much liquid on the wet curtain 203 and it drips, the dripping liquid can fall into the spraying liquid tank 2042 below. This not only effectively collects the spraying liquid, creating conditions for subsequent recycling, but also avoids excessive liquid on the wet curtain 203 from dripping randomly into the external environment, thereby preventing adverse effects such as pollution and corrosion on other equipment.

[0097] In a specific implementation manner, such as Figure 4As shown, wet curtains 203 are provided on both sides of the heat exchanger 201, and a set of spray liquid tanks 2042 are correspondingly arranged below each wet curtain 203; the spray pipeline 2041 includes two groups of first spray pipes 20411, second spray pipes 20412 and two groups of third spray pipes 20413; one ends of the two groups of first spray pipes 20411 are respectively connected to the two groups of spray liquid tanks 2042 in one-to-one correspondence; the other ends of the two groups of first spray pipes 20411 are both connected to the second spray pipe 20412, and the spray pump 2043 is connected to the second spray pipe 20412; the two groups of third spray pipes 20413 correspond to the two groups of wet curtains 203 respectively, and the third spray pipe 20413 is arranged above the corresponding wet curtain 203, and the nozzles are arranged on the third spray pipe 20413.

[0098] In one embodiment, a liquid replenishment port 2044 is provided on the spray liquid tank 2042, and the liquid replenishment port 2044 is used for connecting to an external pipeline; the spray system 204 includes a second liquid replenishment pipe and a liquid level regulating valve 2045; the second liquid replenishment pipe is arranged inside the spray liquid tank 2042, and the inlet is connected to the liquid replenishment port 2044; as Figure 3 shown, the liquid level regulating valve 2045 is arranged inside the spray liquid tank 2042 and is connected to the outlet of the second liquid replenishment pipe; and is in communication connection with the control system.

[0099] In a specific implementation manner, the control system controls the on-off of the second liquid replenishment pipe and the spray liquid tank 2042 by controlling the liquid level regulating valve 2045 according to the liquid level height data of the liquid level regulating valve 2045.

[0100] By providing the liquid replenishment port 2044, the external pipeline can be used to replenish the liquid into the spray liquid tank 2042 to ensure that the liquid in the spray system 204 is sufficient, and by providing the liquid level regulating valve 2045, the detection of the liquid level height in the spray liquid tank 2042 and the control of the on-off of the second liquid replenishment pipe and the spray liquid tank 2042 can be realized; when the liquid level detected by the liquid level regulating valve 2045 is at a low level, the control system controls the liquid level regulating valve 2045 to open, so that the second liquid replenishment pipe is communicated with the spray liquid tank 2042, and the external pipeline transports the liquid into the spray liquid tank 2042 through the second liquid replenishment pipe to supplement the liquid content in the spray liquid tank 2042 to ensure the normal use of the spray system 204; when the liquid level height detected by the liquid level regulating valve 2045 reaches a high level, the control system controls the liquid level regulating valve 2045 to close, disconnecting the second liquid replenishment pipe from the spray liquid tank 2042 to prevent the external pipeline from continuing to transport the liquid into the spray liquid tank 2042 and avoid the excessive overflow of the liquid in the spray liquid tank 2042; realizing the automatic control of the liquid replenishment of the spray water tank.

[0101] In a specific implementation manner, the liquid level regulating valve 2045 is a float valve.

[0102] In one embodiment, a drain port 2046 is provided on the spray liquid tank 2042. The drain port 2046 is arranged below the spray liquid tank 2042, and a second drain valve is provided at the drain port 2046.

[0103] By arranging the drain port 2046 below the spray liquid tank 2042 and providing a second drain valve at the drain port 2046, when it is necessary to drain the liquid in the spray liquid tank 2042, only need to open the second drain valve, and the liquid can flow out smoothly through the drain port 2046; when the draining operation is completed or draining is not required, close the second drain valve. At this time, the drain port 2046 is in a closed state, which can effectively ensure the sealing performance of the spray liquid tank 2042, thereby preventing the liquid in the spray liquid tank 2042 from accidentally flowing out through the drain port 2046, and ensuring the safety and stability of the liquid storage in the spray liquid tank 2042.

[0104] In one embodiment, a spray drain alarm is provided in the control box 6, and the spray drain alarm is communicatively connected to the control system.

[0105] In a specific implementation manner, the control system controls the drain alarm to give an alarm according to the outdoor ambient temperature data. When the temperature of the outdoor environment is less than the second target temperature, the control system outputs an alarm for low outdoor ambient temperature, controls the drain alarm to give an alarm, and prompts the staff to manually open the second drain valve to drain the liquid in the spray liquid tank 2042, so as to prevent the liquid in the spray liquid tank 2042 from freezing due to too low outdoor temperature.

[0106] In another implementation manner, it is also possible that the control system is communicatively connected to the second drain valve. When the temperature of the outdoor environment is less than the second target temperature and after a sixth preset time has elapsed, and the liquid level height detected by the liquid level regulating valve 2045 is higher than the drain port 2046, it means that the staff has not timely opened the second drain valve to drain the liquid in the spray liquid tank 2042. At this time, the control system automatically controls the second drain valve to open to drain the liquid in the spray liquid tank 2042. Specifically, there is no limit to the sixth preset time, and the sixth preset time can be adjusted according to the actual situation on site; the sixth preset time can be six hours, twelve hours or twenty-four hours, etc. Specifically, there is no limit to the second target temperature, and the second target temperature can be adjusted according to the actual situation on site; the second target temperature can be 5°C.
