Description
A self-configuring cold and heat source liquid cooling device
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 31, 2024, with application number 202410133157.5 and application name “A Self-Configuring Cold and Heat Source Liquid Cooling Device,” the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present application relates to the field of liquid cooling technology, and in particular to a self-configuring cold and hot source liquid cooling device. Background Art
[0004] Currently, two common server liquid cooling technologies are immersion cooling and cold plate cooling. Immersion cooling directly immerses the server in a specialized coolant to dissipate heat. However, due to its high overall cost and difficult maintenance, its application is limited. Cold plate cooling utilizes a cold plate in contact with the server's heat-generating components to dissipate heat. The cooling principle is that a water pump drives coolant to continuously flow through the cold plate's internal channels. The coolant then exchanges heat with the server's heat-generating components through the cold plate's walls, removing heat generated by the components.
[0005] In the related art, conventional cold plate liquid cooling systems primarily consist of an outdoor cooling source, a primary pump drive system, a primary piping system, a coolant pump drive heat exchange unit, a secondary piping system, and a water distributor. The system lacks an independent cooling source and must rely on an outdoor cooling source, such as an outdoor chiller or cooling tower, and a primary circulation system to complete heat exchange with the liquid-cooled servers. However, the construction process of a conventional cold plate liquid cooling system requires not only the purchase and installation of outdoor chillers, cooling towers, primary and secondary cooling liquid circulation pipelines, and electrical power, but also involves extensive engineering design, including infrastructure construction and foundation renovation. The system suffers from significant construction difficulties, long construction cycles, and significant resource investment. This makes it difficult to upgrade conventional air-cooled data centers to liquid-cooled data centers using the solutions described in the related art, making it impossible to conveniently and cost-effectively implement cold plate liquid cooling for servers. Furthermore, the heat dissipation state of the outdoor cooling source is closely related to the external environment and is often uncontrollable, potentially leading to problems such as insufficient or excessive cooling capacity provided by the outdoor cooling source.
[0006] Therefore, how to achieve a de-engineered design for cold plate liquid cooling environment construction, conveniently and cost-effectively perform cold plate liquid cooling on servers, and precisely control the cooling supply is a technical problem faced by those skilled in the art.

[0067] The self-configured cold and hot source liquid cooling device provided in this application mainly includes a fuselage, a cold source circulation system, a first heat exchanger, a liquid supply circulation system and a controller. Among them, the fuselage is the main component of the device, mainly used to install and accommodate the remaining components of the device, and the cold source circulation system, the first heat exchanger, the liquid supply circulation system, the controller and other components are all integrated on the fuselage to achieve integrated installation, so as to build a simple cold plate liquid cooling heat dissipation environment in the fuselage. The cold source circulation system is arranged on the fuselage, mainly used to drive the refrigerant to circulate along a preset path, and to refrigerate the refrigerant during the circulation of the refrigerant to cool the refrigerant and form a low-temperature medium, which is mainly used to provide a cold source for the cold plate liquid cooling heat dissipation environment formed. The liquid supply circulation system is arranged on the fuselage, mainly used to drive the coolant to circulate along a preset path, and to make the coolant flow through the cold plate during the circulation of the coolant. The cold plate is kept in close contact with the load (such as a heat-generating element such as a server component), so that the coolant can absorb the heat of the load through the cold plate and dissipate heat to the load. The first heat exchanger is also disposed on the machine body and is specifically connected between the cold source circulation system and the liquid supply circulation system. It is primarily used to achieve heat exchange between the cold source circulation system and the liquid supply circulation system. Specifically, when the refrigerant (low-temperature medium) after cooling flows through the first heat exchanger during circulation, the coolant (high-temperature medium) that has absorbed the load heat also flows through the first heat exchanger during circulation, thereby allowing the refrigerant and the coolant to exchange heat in the first heat exchanger. The coolant that has absorbed the load heat transfers the absorbed heat to the refrigerant, and after cooling again, it continues to circulate and absorb the load heat again, thus repeating the cycle. The controller maintains a signal connection with at least the cold source circulation system and is primarily used to control the operating state of the cold source circulation system based on the actual heat dissipation demand (i.e., cooling capacity demand) of the load, so that the cooling capacity of the refrigerant in the cold source circulation system tends to be equivalent to the heat absorbed by the coolant during each heat exchange with the coolant in the liquid supply circulation system, thereby ensuring that the cooling capacity provided by the cold source circulation system matches the actual heat dissipation demand of the load as much as possible.
[0068] The beneficial effects of the present application are as follows: the refrigerant is cooled by the cold source circulation system and driven to circulate, thereby realizing the supply of cold source; the cooling liquid is driven to circulate and flow through the cold plate by the liquid supply circulation system, thereby realizing cold plate liquid cooling heat dissipation for the load; the first heat exchanger is used to provide a heat exchange place, which enables the coolant in the liquid supply circulation system to exchange the heat of the load to the refrigerant in the cold source circulation system, thereby continuously realizing cold plate liquid cooling heat dissipation for the load; and the cold source circulation system, the first heat exchanger, and the liquid supply circulation system are integrated on the fuselage, and the three are built with the fuselage as the carrier to form a simple cold plate type Liquid cooling environment, thus realizing the de-engineering design of cold plate liquid cooling environment construction, without the need to install additional outdoor chillers, cooling towers, primary and secondary side cooling liquid circulation pipelines, electricity and other facilities in scenarios such as air-cooled data centers, and without the need for engineering design and transformation of the server's heat dissipation scenario. The configuration cost, configuration difficulty and configuration cycle are significantly reduced, which is conducive to promotion in scenarios such as air-cooled data centers; at the same time, the controller controls the working state of the cold source circulation system according to the heat dissipation requirements of the load, and can also ensure that the cooling capacity provided by the cold source circulation system matches the actual heat dissipation requirements of the load as much as possible, avoiding problems such as insufficient or excessive cooling capacity.
[0069] In summary, the self-configuring cold and heat source liquid cooling device provided in this application can realize the de-engineering design of cold plate liquid cooling environment construction, conveniently and low-costly perform cold plate liquid cooling on the server, and accurately control the cooling supply.

[0103] In a specific embodiment provided in the present application, the self-configuring cold and hot source liquid cooling device mainly includes a body 1, a cold source circulation system 2, a first heat exchanger 3, a liquid supply circulation system 4 and a controller.
[0104] Among them, the fuselage 1 is the main component of the device, which is mainly used to install and accommodate the remaining components of the device, and the cold source circulation system 2, the first heat exchanger 3, the liquid supply circulation system 4, the controller and other components are all integrated on the fuselage 1 to achieve integrated installation, so as to build a simple cold plate liquid cooling environment in the fuselage 1.
[0105] The cold source circulation system 2 is arranged on the fuselage 1, and is mainly used to drive the refrigerant to circulate along a preset path, and to perform cooling operations on the refrigerant during the circulation of the refrigerant to cool the refrigerant and form a low-temperature medium. It is mainly used to provide a cold source for the cold plate liquid cooling heat dissipation environment formed.
[0106] The liquid supply circulation system 4 is arranged on the fuselage 1, and is mainly used to drive the coolant to circulate along a preset path, and during the circulation of the coolant, the coolant flows through the cold plate. The cold plate is kept in close contact with the load 7 (such as heating elements such as server components), so that the coolant can absorb the heat of the load 7 through the cold plate and dissipate heat for the load 7.
[0107] The first heat exchanger 3 is also provided on the fuselage 1, specifically connected between the cold source circulation system 2 and the liquid supply circulation system 4, and is mainly used to realize heat exchange between the cold source circulation system 2 and the liquid supply circulation system 4. Specifically, when the refrigerant (low-temperature medium) after cooling flows through the first heat exchanger 3 during the circulation process, the coolant (high-temperature medium) that has absorbed the heat of the load 7 also flows through the first heat exchanger 3 during the circulation process, so that the refrigerant and the coolant exchange heat in the first heat exchanger 3, so that the coolant that has absorbed the heat of the load 7 transfers the absorbed heat to the refrigerant, and after cooling again, continues to circulate and absorb the heat of the load 7 again, thus completing the cycle.
[0108] The controller at least maintains a signal connection with the cold source circulation system 2, and is mainly used to control the working state of the cold source circulation system 2 according to the actual heat dissipation demand (i.e., cooling capacity demand) of the load 7, such as controlling the temperature, flow rate, pressure and other parameters of the refrigerant in the cold source circulation system 2, so that the cooling capacity of the refrigerant in the cold source circulation system 2 tends to be equivalent to the heat absorbed by the coolant each time it exchanges heat with the coolant in the liquid supply circulation system 4, thereby ensuring as much as possible that the cooling capacity provided by the cold source circulation system 2 matches the actual heat dissipation demand of the load 7.
[0109] In this way, the refrigerant is cooled by the cold source circulation system 2 and driven to circulate, so that the cold source supply can be realized; the coolant is driven to circulate and flow through the cold plate by the liquid supply circulation system 4, so that the load 7 can be cooled by the cold plate liquid cooling heat dissipation; the first heat exchanger 3 is used to provide a heat exchange place, so that the coolant in the liquid supply circulation system 4 can exchange the heat of the load 7 with the refrigerant in the cold source circulation system 2, thereby continuously realizing the cold plate liquid cooling heat dissipation of the load 7; and the cold source circulation system 2, the first heat exchanger 3, and the liquid supply circulation system 4 are integrated on the fuselage 1, and the three are built with the fuselage 1 as a carrier to form a simple cold plate. liquid cooling environment, thereby realizing the de-engineering design of the cold plate liquid cooling environment construction. There is no need to install additional outdoor chillers, cooling towers, primary and secondary side cooling liquid circulation pipelines, electricity and other facilities in scenarios such as air-cooled data centers. There is no need to carry out engineering design and transformation of the server's heat dissipation scenario. The configuration cost, configuration difficulty and configuration cycle are significantly reduced, which is conducive to promotion in scenarios such as air-cooled data centers. At the same time, the controller controls the working state of the cold source circulation system 2 according to the heat dissipation requirements of the load 7, and can also ensure that the cooling capacity provided by the cold source circulation system 2 matches the actual heat dissipation requirements of the load 7 as much as possible, avoiding problems such as insufficient or excessive cooling capacity.
[0110] In summary, the self-configuring cold and heat source liquid cooling device provided in this embodiment can realize the de-engineering design of cold plate liquid cooling environment construction, conveniently and cost-effectively perform cold plate liquid cooling on the server, and accurately control the cooling supply.
[0111] In addition, the self-configuring cold and heat source liquid cooling device provided in this embodiment can better adapt to the liquid cooling upgrade and transformation of the current air-cooled data center, without the need for large-scale construction and transformation and shutdown of the existing computer room. It is very suitable for teaching, scientific research, universities, laboratories and other scenarios that require small-scale liquid cooling testing and heat dissipation. It also overcomes the current disadvantages of the cold plate liquid cooling environment that cannot be moved remotely and has a low reuse rate. The integrated design of the self-configuring cold and heat source liquid cooling device can be flexibly moved and reused remotely according to the specific usage scenario.

[0113] In a specific embodiment of the cold source circulation system 2, the cold source circulation system 2 mainly includes a compressor 21, a condenser 22, an expansion valve 23 and an evaporator (the evaporation heat exchange pipe 31 of the first heat exchanger 3). Its main working principle is the refrigeration principle of air conditioning, that is, the refrigeration function is realized by utilizing the physical phenomenon of heat absorption during the gasification process and heat release during the liquefaction process of the refrigerant to take away the heat generated by the load 7 and discharge it into the external environment.
[0114] The outlet of compressor 21 is connected to the inlet of condenser 22, which is in communication with the inlet of expansion valve 23, which is in communication with the inlet of evaporation heat exchange pipe 31 of first heat exchanger 3, and the outlet of evaporation heat exchange pipe 31 of first heat exchanger 3 is in communication with the inlet of compressor 21. Compressor 21 is primarily used to compress low-temperature, low-pressure refrigerant that has undergone heat exchange into high-temperature, high-pressure gas and provide power for the refrigeration cycle, thereby sequentially implementing a refrigeration cycle of compression, condensation, expansion, and evaporation. Compressor 21 can also automatically adjust its operating status according to a controller to achieve energy conservation and efficiency improvement.
[0115] The main function of the condenser 22 is to discharge the heat of the high-temperature and high-pressure refrigerant gas processed by the compressor 21 into the external environment through media such as air and cooling water, and to convert the refrigerant from a high-temperature and high-pressure gasified state into a medium-temperature and high-pressure liquefied state to complete the heat dissipation and cooling operation of the refrigerant.
[0116] The expansion valve 23 is primarily used to throttle medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor. The refrigerant then absorbs heat in the evaporation heat exchange pipe 31 of the first heat exchanger 3, achieving a cooling and heat exchange effect. Simultaneously, the expansion valve 23 controls the flow of refrigerant entering the first heat exchanger 3, ensuring that the refrigerant entering the compressor 21 is entirely gaseous. The expansion valve 23 also controls the valve flow rate based on changes in superheat at the end of the first heat exchanger 3, preventing underutilization of the evaporation area and cylinder knocking.
[0117] In addition, this embodiment also includes a first temperature sensor 24, a second temperature sensor 25, a first pressure sensor 26, and a second pressure sensor 27. The first temperature sensor 24 is primarily used to detect the inlet temperature of the evaporative heat exchange pipe 31 and feed the detected value back to the controller. The second temperature sensor 25 is primarily used to detect the outlet temperature of the evaporative heat exchange pipe 31 and feed the detected value back to the controller. The first pressure sensor 26 is primarily used to detect the inlet pressure of the evaporative heat exchange pipe 31 and feed the detected value back to the controller. The second pressure sensor 27 is primarily used to detect the outlet pressure of the evaporative heat exchange pipe 31 and feed the detected value back to the controller. The controller can determine the heat exchange capacity of the first heat exchanger 3 based on the detection data from the first temperature sensor 24, the second temperature sensor 25, the first pressure sensor 26, and the second pressure sensor 27, and further determine the current heat dissipation requirement of the load 7. Ultimately, the operating state of the compressor 21 is controlled based on the current heat dissipation requirement of the load 7, ensuring that the heat transferred from the load 7 to the coolant is equal to the heat released by the coolant to the refrigerant, thereby preventing the coolant from being overcooled or overheated and maintaining a constant temperature circulation mode as much as possible. For example, when it is determined that the heat exchange amount is large, the power of the compressor 21 is increased accordingly, and vice versa.
[0118] This embodiment also includes a filter-dehumidifier 28. Specifically, this filter-dehumidifier 28 is connected between the outlet of the condenser 22 and the inlet of the expansion valve 23 and is primarily used to filter water and impurities from the refrigerant. Specifically, the interior of the filter-dehumidifier 28 utilizes a molecular sieve structure, which purifies the system and prevents pipeline blockages caused by excessive refrigerant moisture and impurities, effectively reducing the likelihood of system failures and pipeline damage.
[0119] This embodiment also includes a third temperature sensor 29, a third pressure sensor 210, and a fourth temperature sensor 211. Specifically, the third temperature sensor 29 is used to detect the refrigerant temperature at the outlet of the compressor 21, and the third pressure sensor 210 is used to detect the refrigerant pressure at the outlet of the compressor 21. The first pressure sensor 26, the second pressure sensor 27, and the third pressure sensor 210 are all composed of on-off valves and pressure sensors. This combination allows for calibration and replacement of the pressure sensors without shutting down the system. The fourth temperature sensor 211 is used to detect the refrigerant temperature at the outlet of the condenser 22. Similarly, the detection values of the third temperature sensor 29, the third pressure sensor 210, and the fourth temperature sensor 211 are all fed back to the controller, allowing the controller to determine whether the operating status of the cold source circulation system 2 is normal based on specific usage requirements and to adjust the operating status of the entire cold source circulation system 2 based on the specific heat dissipation requirements of the load 7.
[0120] As shown in FIG. 7 , FIG. 7 is a schematic diagram of the specific structure of the first heat exchanger 3 .
[0121] In a specific embodiment of the first heat exchanger 3, two channels are defined within the first heat exchanger 3: an evaporation heat exchange pipe 31 and a condensation heat exchange pipe 32. The evaporation heat exchange pipe 31 primarily serves to carry the refrigerant in the cooling source circulation system 2, achieving heat absorption and evaporation. The condensation heat exchange pipe 32 primarily serves to carry the coolant in the liquid supply circulation system 4 or the intermediate heat transfer medium in the isolation circulation system 5, achieving heat release and condensation. Generally, the first heat exchanger 3 employs a brazed, integrated design.
[0122] As shown in FIG9 , FIG9 is a schematic diagram of the specific structure of the liquid supply circulation system 4 .
[0123] In a specific embodiment of the liquid supply circulation system 4, the liquid supply circulation system 4 mainly includes a temperature control module 41, a cold plate liquid supply module 42, and a cold plate liquid return module 43. Among them, the inlet of the temperature control module 41 is connected to the outlet of the condensing heat exchange pipe 32 of the first heat exchanger 3, and is mainly used to adjust the temperature of the coolant (mainly heating) to achieve constant temperature liquid supply to the load 7; and the temperature control module 41 is connected to the controller signal to control the working state of the temperature control module 41 according to the heat dissipation demand of the load 7. The inlet of the cold plate liquid supply module 42 is connected to the outlet of the temperature control module 41, and the outlet of the cold plate liquid supply module 42 is connected to the inlet of the load 7, and is mainly used to draw out the constant temperature coolant in the temperature control module 41 to supply liquid and dissipate heat to the load 7. The inlet of the cold plate liquid return module 43 is connected to the outlet of the load 7, and the outlet of the cold plate liquid return module 43 is connected to the inlet of the condensation heat exchange pipe 32 of the first heat exchanger 3, which is used to drive the coolant to circulate, so as to transfer the heat of the load 7 to the condensation heat exchange pipe 32 of the first heat exchanger 3 through the coolant, and then transfer it to the refrigerant in the cold source circulation system 2, and finally flow back to the warming module 41, and the cycle repeats.
[0124] As shown in FIG10 , FIG10 is a schematic diagram of the specific structure of the temperature adjustment module 41 .
[0125] In a specific embodiment of the temperature control module 41 , the temperature control module 41 mainly includes a temperature control water tank 411 , a heater 412 and a water tank temperature sensor 413 .
[0126] Among them, the temperature-controlled water tank 411 specifically adopts a stainless steel integrated welding molding process, which can effectively protect the water quality of the coolant and is mainly used to temporarily store a certain amount of coolant. The heater 412 is set in the temperature-controlled water tank 411, and is mainly used to heat and increase the temperature of the coolant in the temperature-controlled water tank 411. When the coolant temperature is lower than the temperature required by the server, the coolant is automatically heated and increased in temperature to avoid the coolant temperature being too low, causing condensation in the server liquid cooling pipe, and the coolant temperature not meeting the requirements. Of course, if you want to adjust the temperature of the coolant in the temperature-controlled water tank 411, you only need to turn off the heater 412. As the coolant after releasing heat continues to enter the temperature-controlled water tank 411, the temperature of the coolant will drop rapidly. The water tank temperature sensor 413 is arranged in the temperature-controlled water tank 411, and is mainly used to detect the temperature of the coolant in the temperature-controlled water tank 411. The water tank temperature sensor 413 and the heater 412 are both connected to the controller signal, so that the controller controls the working state of the heater 412 according to the detection value of the water tank temperature sensor 413 and the heat dissipation demand of the load 7, ensuring that the temperature of the coolant in the temperature-controlled water tank 411 is maintained within a constant range that matches the cooling demand of the load 7.
[0127] In order to control the temporary storage amount of the coolant in the temperature-regulating water storage tank 411 , a liquid level meter 414 , a liquid replenishing mechanism 415 and a liquid draining mechanism 416 are additionally provided in this embodiment.
[0128] The liquid level gauge 414 is located within the temperature-controlled water tank 411 and is primarily used to monitor the level of the coolant temporarily stored therein in real time, maintaining a signal connection with the controller. This level gauge 414 displays the coolant capacity within the temperature-controlled water tank 411 in real time via a display on the body 1. When the coolant level is excessively high or insufficient, it issues an alarm signal and provides feedback to the controller, enabling the controller to automatically control the operating states of the refill mechanism 415 and the drain mechanism 416, ensuring timely refill and drain operations. Furthermore, a liquid level visualization window can be configured within the temperature-controlled water tank 411 to facilitate liquid level monitoring.
[0129] The refill mechanism 415 is connected to the temperature-controlled water tank 411 and specifically includes an automatic refill component 4151 and a manual refill component 4152. The manual refill component 4152 mainly includes a manual refill on-off valve, a refill filter 4210, and a water tank refill pump. One end of the manual refill component 4152 is connected to the upper end of the temperature-controlled water tank 411, and the other end is connected to an external, non-pressurized server coolant container. When the temperature-controlled water tank 411 requires manual refill, the staff manually opens the manual refill on-off valve and starts the water tank refill pump to perform the refill operation. At the same time, the refill filter 4210 can filter and clean the replenished coolant to prevent impurities in the coolant from entering the temperature-controlled water tank 411. One end of the automatic refill component 4151 is connected to the upper end of the temperature-controlled water tank 411, and the other end is connected to an external, pressurized coolant delivery pipeline, on which a switch solenoid valve is installed. When the temperature-controlled water storage tank 411 outputs the refilling demand, the switch solenoid valve automatically opens, and the coolant is automatically transported to the inside of the temperature-controlled water storage tank 411 using the external pressurized coolant delivery pipeline. When the refilling is completed, the switch solenoid valve automatically closes.
[0130] One end of the drainage mechanism 416 is connected to the lower end of the temperature-regulating water tank 411, and is mainly used to realize the drainage operation of the temperature-regulating water tank 411. An electric on-off valve is provided on it. When the temperature-regulating water tank 411 needs to be drained, the electric on-off valve automatically opens under the control of the controller to automatically perform the coolant discharge operation.
[0131] To prevent overflow due to excessive coolant in the thermostatic water tank 411, a relief valve 417 is provided in this embodiment. Specifically, the inlet of relief valve 417 is connected to a preset position at the upper end of the thermostatic water tank 411, located at the highest safe water level of the thermostatic water tank 411. The outlet of relief valve 417 is directly connected to the outside world, primarily for ensuring safe overflow. When the coolant in the thermostatic water tank 411 reaches the highest safe water level, the excess coolant is automatically discharged to the outside world through relief valve 417, preventing system failures caused by excessive water.
[0132] To ensure stable pressure within the temperature-controlled water tank 411, a pressure regulator 418 is added in this embodiment. Specifically, the pressure regulator 418 is connected to the top of the temperature-controlled water tank 411 via a static pressure line and is primarily used to stabilize the pressure within the temperature-controlled water tank 411. Specifically, when the pressure within the temperature-controlled water tank 411 changes, the pressure regulator 418 automatically utilizes the external atmospheric pressure to stabilize the pressure accordingly. Furthermore, a dustproof end cap is provided on the top of the pressure regulator 418 to prevent foreign particles from entering the temperature-controlled water tank 411 and contaminating the coolant.
[0133] As shown in FIG11 , FIG11 is a schematic diagram of the specific structure of the cold plate liquid supply module 42 .
[0134] In a specific embodiment of the cold plate liquid supply module 42, the cold plate liquid supply module 42 mainly includes a distal liquid inlet pipe 421 and a proximal liquid inlet pipe 422. The inlet of the distal liquid inlet pipe 421 is connected to the outlet of the condensing heat exchange pipe 32 of the first heat exchanger 3, and the outlet of the distal liquid inlet pipe 421 is connected to the temperature-controlled water tank 411 (the upper end). Specifically, the distal liquid inlet pipe 421 is mainly used to transport the coolant that has exchanged heat in the first heat exchanger 3 (or the second heat exchanger 6) to the temperature-controlled water tank 411 to control the temperature of the coolant. The inlet of the proximal liquid inlet pipe 422 is connected to the temperature-controlled water tank 411 (the lower end), and the outlet of the proximal liquid inlet pipe 422 is connected to the inlet of the load 7. Specifically, the proximal liquid inlet pipe 422 is mainly used to transport the coolant in the temperature-controlled water tank 411, which tends to be constant temperature, to the load 7 to perform cold plate liquid cooling on the load 7.
[0135] Considering that when the heat generation of the load 7 is low, the cooling capacity of the coolant is likely to be excessive, it is usually necessary to activate the heater 412 in the temperature-controlled water storage tank 411 to heat the coolant. To reduce the load on the heater 412 and reduce energy consumption, a remote bypass inlet pipe 423 and a remote bypass regulating valve 424 are added in this embodiment. The inlet of the remote bypass inlet pipe 423 is connected to the remote inlet pipe 421, and the outlet of the remote bypass inlet pipe 423 is connected to the cold plate return module 43. The remote bypass regulating valve 424 is provided on the remote bypass inlet pipe 423, and its valve opening is adjustable to control the flow rate of coolant entering the remote bypass inlet pipe 423 from the remote inlet pipe 421. At the same time, the remote bypass regulating valve 424 is connected to the controller signal. Under normal conditions, the valve of the remote bypass regulating valve 424 remains closed, and all coolant enters the temperature-controlled water tank 411 through the remote liquid inlet pipe 421; when the detection value of the water tank temperature sensor 413 is lower than the preset threshold value, it indicates that there is too much cold water in the current temperature-controlled water tank 411. At this time, the valve of the remote bypass regulating valve 424 is opened, so that part of the coolant directly enters the cold plate return module 43 through the remote bypass liquid inlet pipe 423, and no longer enters the temperature-controlled water tank 411, so that the temperature of the coolant in the temperature-controlled water tank 411 can quickly return to the preset temperature under the heating action of the heater 412.
[0136] Considering that the coolant entering the temperature-regulating water tank 411 through the distal liquid inlet pipe 421 primarily flows downward from the top of the temperature-regulating water tank 411, which may result in uneven temperatures of the coolant in each layer within the temperature-regulating water tank 411, a water divider 425 is provided in this embodiment to address this issue. Specifically, the water divider 425 is disposed within the temperature-regulating water tank 411, with its inlet communicating with the outlet of the distal liquid inlet pipe 421. The water divider 425 is provided with multiple outlets, each distributed along the height of the temperature-regulating water tank 411. With this arrangement, after entering the water divider 425, the coolant simultaneously flows out from each outlet of the water divider 425, each located at a different height within the temperature-regulating water tank 411. Consequently, the coolant is evenly divided into multiple streams, which simultaneously flow out to different heights within the temperature-regulating water tank 411, thereby ensuring that the temperature of the coolant in each layer within the temperature-regulating water tank 411 is uniform.
[0137] For the proximal liquid inlet pipe 422, similar to the aforementioned distal liquid inlet pipe 421, when the heat generation of the load 7 is low, the cooling capacity of the coolant is likely to be excessive. If all the coolant passing through the proximal liquid inlet pipe 422 enters the load 7, it may cause the load 7 to be overcooled, affecting the normal operation of the load 7. To address this issue, a proximal bypass liquid inlet pipe 426 and a proximal bypass regulating valve 427 are additionally provided in this embodiment.
[0138] The inlet of the proximal bypass inlet pipe 426 is connected to the proximal inlet pipe 422, and the outlet of the proximal bypass inlet pipe 426 is connected to the cold plate return module 43. A proximal bypass regulating valve 427 is provided on the proximal bypass inlet pipe 426. Its valve opening is adjustable to control the flow of coolant entering the proximal bypass inlet pipe 426 from the proximal inlet pipe 422. The proximal bypass regulating valve 427 is also connected to a controller signal. Under normal conditions, the proximal bypass regulating valve 427 remains closed, and all coolant enters the load 7 through the proximal inlet pipe 422. When the cooling liquid demand of load 7 is lower than the minimum return liquid flow rate of the cold plate return liquid module 43, it means that the current heating value of load 7 is very low. At this time, the valve of the proximal bypass regulating valve 427 is opened, allowing part of the cooling liquid to directly enter the cold plate return liquid module 43 through the proximal bypass liquid inlet pipe 426, and no longer enter the load 7, thereby avoiding overcooling of load 7.
[0139] To disinfect the coolant, a disinfection component 428 is added in this embodiment. Specifically, the disinfection component 428 is provided on the proximal liquid inlet pipe 422 and can be a UV sterilizer. It mainly uses ultraviolet sterilization technology to actively disinfect the coolant (such as bacteria, viruses, etc.), preventing coolant water contamination caused by excessive microorganisms in the coolant, and preventing corrosion damage to components.
[0140] To enable intuitive monitoring of the coolant circulation status, this embodiment adds a monitoring component 429. Specifically, the monitoring component 429 is provided on the proximal liquid inlet pipe 422 and can be made of transparent glass. It is mainly used for personnel to monitor and check the coolant circulation status, such as the degree of water turbidity, impurities and bubbles in the water.
[0141] To filter and sample the coolant's water quality, this embodiment includes a filter 4210, a first on-off valve 4211, and a water sampling valve 4212. At least two filters 4210 are provided, and two are used as an example in this embodiment. These two filters 4210 are connected in parallel on the proximal inlet pipe 422. Specifically, they can utilize a stainless steel flushable filter element design, which can remove particulate matter from the coolant and ensure that the coolant's water quality meets the requirements for coolant use. Furthermore, the parallel connection of the two filters 4210 on the proximal inlet pipe 422 creates a "one active, one standby" dual filtration pipeline configuration, ensuring that even if a problem with one filtration pipeline occurs or the filter element requires cleaning or replacement, the system's normal operation is not affected. First on-off valves 4211 are located at the inlet and outlet of each filter 4210 to control the on / off status of each filter 4210. Water sampling valves 4212 are connected to the inlet of each filter 4210 to sample and discharge the coolant. With this arrangement, when the filter element of one filter 4210 requires maintenance, the two first on-off valves 4211 corresponding to that filter 4210 need only be closed, and the filter element maintenance work performed on that filter 4210 can be performed. The other filter 4210 will remain unaffected and will continue to filter the coolant normally, thereby enabling the filter element cleaning and replacement of filter 4210 and pipeline maintenance without shutting down the system. Furthermore, staff can conveniently sample the coolant using the water sampling valve 4212, allowing coolant sampling and inspection without shutting down the system.
[0142] Furthermore, in order to automatically detect the working status of each filter 4210, a monitoring pressure sensor 4213 is added in this embodiment. Specifically, two monitoring pressure sensors 4213 are provided, both of which are arranged on the proximal liquid inlet pipe 422 and located at the inlet and outlet of each filter 4210. The two monitoring pressure sensors 4213 together constitute the filter element status monitoring unit of the filter 4210. The filter element status of the filter 4210 is mainly determined and monitored by comparing the pressure difference between the inlet and outlet of the filter 4210. When the difference in the detection value of the monitoring pressure sensors 4213 at both ends exceeds a preset threshold, the controller issues a filter element maintenance alarm, allowing staff to conduct timely inspections and filter element replacement operations.
[0143] In addition, in order to accurately detect the overall operating status of the cold plate liquid supply module 42, a fourth pressure sensor 4214, a fifth temperature sensor 4215, a first flow meter 4216, a fifth pressure sensor 4217 and a sixth temperature sensor 4218 are further provided in this embodiment.
[0144] Among them, the fourth pressure sensor 4214, the fifth temperature sensor 4215 and the first flow meter 4216 together constitute the coolant status monitoring unit in the remote liquid inlet pipe 421, which can read and output the pressure, temperature and flow data of the low-temperature coolant that has completed heat exchange and cooling, and upload them to the controller synchronously, so that the controller can adjust the relevant operating parameters of the equipment in time according to the feedback relevant data information and the working conditions.
[0145] The fifth pressure sensor 4217 and the sixth temperature sensor 4218 are used to monitor the coolant pressure and coolant temperature at the inlet of load 7, respectively, to ensure that the coolant parameters entering load 7 meet the actual cooling requirements of load 7. Furthermore, the fifth pressure sensor 4217 and the seventh pressure sensor 4310 form a key component in the system's differential pressure operating mode.
[0146] As shown in FIG12 , FIG12 is a schematic diagram of the specific structure of the cold plate liquid return module 43 .
[0147] In a specific embodiment of the cold plate liquid return module 43 , the cold plate liquid return module 43 mainly includes a proximal liquid return pipe 431 , a distal liquid return pipe 432 , a proximal circulation pump 433 , and a distal circulation pump 434 .
[0148] Among them, the inlet of the proximal liquid return pipe 431 is connected to the outlet of the load 7, and the outlet of the proximal liquid return pipe 431 is connected to the temperature-controlled water tank 411. It is mainly used to draw out the coolant that has absorbed the heat of the load 7 and reintroduce this part of the coolant into the temperature-controlled water tank 411, so that the temperature-controlled water tank 411 can use the heat of this part of the coolant to heat the coolant with too low a temperature, thereby saving energy consumption of the heater 412.
[0149] The inlet of the remote liquid return pipe 432 is connected to the temperature-controlled water storage tank 411, and the outlet of the remote liquid return pipe 432 is connected to the inlet of the condensation heat exchange pipe 32 of the first heat exchanger 3 (or the heat release pipe 62 of the second heat exchanger 6). It is mainly used to introduce the coolant that has absorbed the heat of the load 7 and passed through the temperature-controlled water storage tank 411 into the first heat exchanger 3 (or the second heat exchanger 6), and transfer all the remaining heat to the refrigerant in the cold source circulation system 2, so as to achieve re-cooling of the coolant and then flow back to the remote liquid inlet pipe 421.
[0150] The proximal circulation pump 433 is provided on the proximal liquid return pipe 431 and is primarily used to drive the coolant from the outlet of the load 7 to the temperature-controlled water storage tank 411. The distal circulation pump 434 is provided on the distal liquid return pipe 432 and is primarily used to drive the coolant from the temperature-controlled water storage tank 411 to the inlet of the condensing heat exchange pipe 32 of the first heat exchanger 3 (or the heat release pipe 62 of the second heat exchanger 6).
[0151] Considering that the proximal circulation pump 433 may be difficult to accurately connect with the proximal return liquid pipe 431 due to factors such as installation errors, a vibration damping pipe 435 is added in this embodiment to address this issue. Specifically, the vibration damping pipe 435 is disposed at both ends of the inlet and outlet of the proximal circulation pump 433. The vibration damping pipe 435 is elastic and can produce elastic deformation. It is mainly used to eliminate installation errors when the proximal circulation pump 433 and the proximal return liquid pipe 431 are connected, thereby improving the installation tolerance and facilitating installation. At the same time, when the vibration generated by the proximal circulation pump 433 during operation is transmitted to the vibration damping pipe 435 at both ends, the vibration energy can be absorbed by the elastic deformation of the vibration damping pipe 435, thereby reducing the impact vibration on the entire proximal return liquid pipe 431 and improving the operating stability of the proximal circulation pump 433.
[0152] The same is true for the remote circulation pump 434. Vibration-damping pipes 435 can also be provided at both ends of the inlet and outlet of the remote circulation pump 434. The working principle and beneficial effects thereof are described in the previous paragraph and will not be repeated here.
[0153] Furthermore, this embodiment also provides second on-off valves 436 at both ends of the inlet and outlet of the proximal circulation pump 433. Specifically, the second on-off valves 436 are primarily used to control the on-off state of the inlet and outlet of the proximal circulation pump 433. When the proximal circulation pump 433 requires repair and maintenance, the proximal circulation pump 433 can be disconnected from the proximal liquid return pipe 431. With this arrangement, only the coolant in the proximal circulation pump 433 region on the proximal liquid return pipe 431 needs to be drained, and subsequent repair and maintenance operations on the proximal liquid return pipe 431 can be performed, thereby avoiding the waste of manpower and material resources caused by large-scale drainage and preventing increased repair difficulty and cost.
[0154] The same is true for the remote circulation pump 434. A second on-off valve 436 can also be set at both ends of the inlet and outlet of the remote circulation pump 434. Its working principle and beneficial effects are described in the previous paragraph and will not be repeated here.
[0155] Furthermore, considering that in the aforementioned embodiment, the water distributor 425 is provided in the temperature-controlled water tank 411 to achieve uniform coolant discharge and temperature uniformity, similarly, in this embodiment, a water collector 437 is also provided in the temperature-controlled water tank 411. Specifically, the water collector 437 is provided in the temperature-controlled water tank 411, typically away from the water distributor 425, such as on either side of the temperature-controlled water tank 411. The outlet of the water collector 437 is connected to the inlet of the distal liquid return pipe 432, and the water collector 437 is provided with multiple inlets, each of which is distributed along the length direction of the water collector 437, that is, along the height direction of the temperature-controlled water tank 411. It is mainly used to ensure that the coolant at each layer in the temperature-controlled water tank 411 can be pumped out to the distal liquid return pipe 432 by the distal circulation pump 434, thereby avoiding pumping out only the coolant in a local area in the temperature-controlled water tank 411. On the one hand, it speeds up the flow efficiency of the coolant in the temperature-controlled water tank 411, and on the other hand, it cooperates with the water distributor 425 to further enhance the temperature uniformity of each layer of coolant in the temperature-controlled water tank 411.
[0156] To prevent the distal return pipe 432 from bursting due to overpressure, a safety valve 438 is provided in this embodiment. Specifically, the safety valve 438 is located at the outlet of the distal return pipe 432. It automatically relieves pressure when the distal return pipe 432 becomes clogged, causing overpressure, thereby preventing bursting and damage to the pump drive. Of course, the safety valve 438 can also be located at the outlet of the proximal return pipe 431. Its operating principles and beneficial effects are similar and will not be further described here.
[0157] In addition, in order to accurately detect the overall operating status of the cold plate liquid return module 43, a sixth pressure sensor 439, a seventh pressure sensor 4310, a seventh temperature sensor 4311, a second flow meter 4312, and an eighth pressure sensor 4313 are further provided in this embodiment.
[0158] Among them, the sixth pressure sensor 439 is mainly used for reading and outputting the pressure at the outlet of the remote liquid return pipe 432. The controller uses this pressure value to determine whether the remote circulation pump 434 can work normally, and at the same time compares and analyzes it with the value measured by the fourth pressure sensor 4214 to realize the judgment of the working status of the first heat exchanger 3 (or the second heat exchanger 6).
[0159] The seventh pressure sensor 4310 is mainly used to read and output the outlet pressure of the load 7, and feed back the detection value to the controller. The controller compares this pressure value with the detection value of the fifth pressure sensor 4217 to determine whether the current system status can meet the actual use requirements of the load 7, and to facilitate the controller to realize the system pressure difference control mode operation.
[0160] The seventh temperature sensor 4311 is mainly used to detect the temperature of the coolant that has absorbed the heat of the load 7, and feed back the detection value to the controller. The controller compares this temperature value with the detection value of the sixth temperature sensor 4218 to determine whether the current system status can meet the actual working needs.
[0161] The second flow meter 4312 is mainly used to detect the coolant flow in the proximal liquid return pipe 431 and feed back the detection value to the controller so that the controller can grasp the coolant flow information in real time and make relevant adjustments according to actual needs.
[0162] The eighth pressure sensor 4313 is mainly used to detect the pressure at the outlet of the proximal liquid return pipe 431, and to feed back the detection value to the controller so that the controller can determine whether the proximal circulation pump 433 can work normally based on the pressure value, and then adjust the operating status of the proximal circulation pump 433 according to the specific working conditions.
[0163] As shown in Figures 3 and 5, Figure 3 is a schematic diagram of the system architecture in the second specific implementation manner provided by this application, and Figure 5 is a schematic diagram of specific system modules of the system architecture shown in Figure 3.
[0164] In the second specific embodiment provided in the present application, considering that the cold source circulation system 2 and the liquid supply circulation system 4 are relatively close when they are integrated on the fuselage 1, the cold source and the heat source may affect each other, resulting in adverse consequences. At the same time, during the operation of the server, the heat generation of the load 7 may change frequently in a short period of time, thereby causing the cooling capacity required by the liquid supply circulation system 4 to also change frequently synchronously, which may eventually lead to the frequent start-stop phenomenon of the cold source circulation system 2 (similar to the frequent start-stop of the air conditioner), thereby causing abnormally high energy consumption. In view of this, in this embodiment, the self-configured cold and hot source liquid cooling device includes, in addition to the fuselage 1, the cold source circulation system 2, the first heat exchanger 3, the liquid supply circulation system 4, and the controller, an isolation circulation system 5 and a second heat exchanger 6. Similarly, the isolation circulation system 5 and the second heat exchanger 6 are also integrated on the fuselage 1.
[0165] The primary function of the isolation circulation system 5 is to act as a bridge for heat transfer. It utilizes its intermediate heat transfer medium to transfer the heat absorbed by the coolant to the refrigerant in the cold source circulation system 2, thereby cooling the coolant and providing coolant at a specified temperature to the load 7. Furthermore, the isolation circulation system 5 acts as a buffer, physically isolating the cold source circulation system 2 from the liquid supply circulation system 4. This prevents the cold source and heat source from interfering with each other, while also preventing frequent starts and stops of the cold source circulation system 2 due to frequent changes in the cooling capacity required by the liquid supply circulation system 4.
[0166] Specifically, the isolation circulation system 5 is arranged between the cold source circulation system 2 and the liquid supply circulation system 4, and is used to drive the intermediate heat transfer medium to circulate along a preset path, and transfer the heat of the coolant in the liquid supply circulation system 4 to the refrigerant in the cold source circulation system 2 through the first heat exchanger 3.
[0167] As shown in FIG8 , FIG8 is a schematic diagram of the specific structure of the second heat exchanger 6 .
[0168] The second heat exchanger 6 is connected between the isolation circulation system 5 and the liquid supply circulation system 4, and is used to exchange heat between the intermediate heat transfer medium and the coolant after absorbing heat. Specifically, the structure of the second heat exchanger 6 is similar to that of the first heat exchanger 3, and it includes a heat absorption pipe 61 and a heat release pipe 62. The heat absorption pipe 61 is used to circulate the intermediate heat transfer medium in the isolation circulation system 5, and the heat release pipe 62 is used to circulate the coolant in the liquid supply circulation system 4, thereby absorbing heat from the intermediate heat transfer medium and releasing heat from the coolant.
[0169] With such an arrangement, after the coolant absorbs the heat of the load 7, it can first exchange heat with the low-temperature intermediate heat-conducting medium in the second heat exchanger 6, transfer the heat to the intermediate heat-conducting medium, and then the intermediate heat-conducting medium continues to circulate and transfer the heat to the refrigerant again, realizing a two-step heat transfer process of the load 7. Compared with the aforementioned first specific embodiment, the heat transfer distance and process are slightly longer, but the physical isolation of the cold source and the heat source is realized, and a buffer is realized between the cold source circulation system 2 and the liquid supply circulation system 4.
[0170] As shown in FIG13 , FIG13 is a schematic diagram of the specific structure of the isolation circulation system 5 .
[0171] In a specific embodiment of the isolation circulation system 5 , the isolation circulation system 5 mainly includes an isolation liquid supply module 51 and an isolation liquid return module 52 .
[0172] The isolated liquid supply module 51 as a whole is used to transport the intermediate heat transfer medium after releasing heat in the first heat exchanger 3 to the second heat exchanger 6. Specifically, the inlet of the isolated liquid supply module 51 is connected to the outlet of the condensing heat exchange pipe 32 of the first heat exchanger 3, and the outlet of the isolated liquid supply module 51 is connected to the inlet of the heat absorption pipe 61 of the second heat exchanger 6.
[0173] The isolated liquid return module 52 serves as the power center of the isolated circulation system 5, primarily providing power for the circulation of the intermediate heat transfer medium. It also performs multiple functions, including power output, voltage and flow stabilization, and system status monitoring. Specifically, the inlet of the isolated liquid return module 52 communicates with the outlet of the heat absorption pipe 61 of the second heat exchanger 6, while the outlet of the isolated liquid return module 52 communicates with the inlet of the condensing heat exchange pipe 32 of the first heat exchanger 3.
[0174] As shown in FIG14 , FIG14 is a schematic diagram of the specific structure of the isolation liquid supply module 51 .
[0175] In a specific embodiment of the isolated liquid supply module 51, the isolated liquid supply module 51 primarily includes a main liquid supply pipe 511 and a branch liquid supply pipe 512. The inlet of the main liquid supply pipe 511 communicates with the outlet of the condensing heat exchange pipe 32 of the first heat exchanger 3, and the outlet of the main liquid supply pipe 511 communicates with the inlet of the heat absorption pipe 61 of the second heat exchanger 6. The inlet of the branch liquid supply pipe 512 communicates with the main liquid supply pipe 511, and the outlet of the branch liquid supply pipe 512 communicates with the isolated liquid return module 52. At the same time, a branch regulating valve 513 is provided on the branch liquid supply pipe 512. The branch regulating valve 513 is in a closed state under normal conditions. However, when the cooling capacity supplied by the main liquid supply pipe 511 to the heat absorption pipe 61 of the second heat exchanger 6 is greater than the heat released by the heat release pipe 62 of the second heat exchanger 6, it means that the cooling capacity of the intermediate heat transfer medium is too large. At this time, the branch regulating valve 513 is automatically opened under the control of the controller, so that part of the intermediate heat transfer medium directly enters the isolation return liquid module 52 through the branch liquid supply pipe 512, and no longer passes through the second heat exchanger 6, thereby reducing the amount of intermediate heat transfer medium entering the heat absorption pipe 61 of the second heat exchanger 6, thereby avoiding overcooling of the coolant in the liquid supply circulation system 4, and ensuring that the heat absorption of the isolation circulation system 5 is consistent with the heat generation of the load 7.
[0176] In addition, in order to accurately detect the overall operating status of the isolated liquid supply module 51, an eighth temperature sensor 514 and a ninth temperature sensor 515 are further provided in this embodiment.
[0177] Among them, the eighth temperature sensor 514 is mainly used to detect the temperature of the intermediate heat transfer medium after heat exchange in the first heat exchanger 3, and feed back the detection value to the controller so that the controller can adjust the operating state of the isolation circulation system 5 according to specific usage requirements.
[0178] The ninth temperature sensor 515 is mainly used to detect the temperature of the intermediate heat transfer medium that is about to enter the second heat exchanger 6, and to feed back the detection value to the controller so that the controller can adjust the operating state of the isolation circulation system 5 according to the detection value and the specific operating conditions of the system to ensure that the intermediate heat transfer medium entering the second heat exchanger 6 meets the system requirements.
[0179] Furthermore, this embodiment also includes an automatic exhaust valve 516. Specifically, the automatic exhaust valve 516 is provided at the outlet of the main liquid supply pipe 511 and is primarily used to automatically discharge gas mixed in the main liquid supply pipe 511, thereby preventing cavitation damage to the pipe caused by gas in the pipe.
[0180] As for the remaining auxiliary components of the isolation liquid supply module 51 , please refer to the aforementioned cold plate liquid supply module 42 and will not be described in detail here.
[0181] As shown in FIG. 15 , FIG. 15 is a schematic diagram of the specific structure of the isolation liquid return module 52 .
[0182] In a specific embodiment of the isolated liquid return module 52, the isolated liquid return module 52 primarily includes a main liquid return pipe 521, an isolated circulation pump 522, and a surge tank 523. The inlet of the main liquid return pipe 521 is connected to the outlet of the heat absorption pipe 61 of the second heat exchanger 6, and the outlet of the main liquid return pipe 521 is connected to the inlet of the condensing heat exchange pipe 32 of the first heat exchanger 3. The isolated circulation pump 522 is disposed on the main liquid return pipe 521 and is primarily used to drive the intermediate heat transfer medium to circulate through the main liquid supply pipe 511 and the main liquid return pipe 521. The surge tank 523 is connected in series with the main liquid return pipe 521 and is primarily used to control the pressure and / or flow of the intermediate heat transfer medium in the isolated circulation system 5 according to preset target parameters. With this arrangement, driven by the isolated circulation pump 522, the intermediate heat transfer medium can circulate through the main liquid return pipe 521, the surge tank 523, and the main liquid supply pipe 511.
[0183] In a specific embodiment of the isolation circulation pump 522, at least two isolation circulation pumps 522 are provided. This embodiment uses two isolation circulation pumps 522 as an example for illustration, and the two isolation circulation pumps 522 are connected in parallel to the main return liquid pipe 521. Furthermore, a third on-off valve 524 is provided at both ends of the inlet and outlet of each isolation circulation pump 522. The third on-off valve 524 is primarily used to control the on-off state of each isolation circulation pump 522 at both ends of the inlet and outlet. When the isolation circulation pump 522 requires maintenance, the isolation circulation pump 522 can be disconnected from its branch circuit. Thus, each third on-off valve 524 and each isolation circulation pump 522 together constitute the pump drive assembly of the isolation circulation system 5. The pump drive assembly utilizes a "one in use, one in standby" dual pump drive patrol design. This design ensures that the normal operation of the system is not affected if a problem in one circuit requires maintenance. Furthermore, it prevents motor overheating, thermal degradation, decreased efficiency, and shortened service life caused by prolonged operation of a single circuit, effectively improving the service life and operating efficiency of the pump drive assembly. At the same time, the two third on-off valves 524 cooperate to realize the on-off control of the branches where each isolation circulation pump 522 is located, thereby realizing the maintenance of related parts such as the pump drive components without stopping the machine, thereby avoiding the waste of manpower and material resources caused by large-scale drainage, and preventing the increase in maintenance difficulty and cost.
[0184] In addition, in order to accurately detect the overall operating status of the isolation liquid return module 52, a ninth pressure sensor 525, a tenth temperature sensor 526, a third flow meter 527, a tenth pressure sensor 529 and an eleventh temperature sensor 5210 are further provided in this embodiment.
[0185] Among them, the ninth pressure sensor 525 is mainly used to detect the outlet pressure of the heat absorption pipe 61 of the second heat exchanger 6, and feed back the detection value to the controller, so that the controller compares this pressure value with the inlet pressure of the heat absorption pipe 61 of the second heat exchanger 6, so as to determine whether the current system operation status meets the actual use requirements and facilitates the implementation of the system pressure difference control mode.
[0186] The tenth temperature sensor 526 is mainly used to detect the temperature of the intermediate heat-conducting medium that absorbs the heat of the coolant, and feeds back the detection value to the controller, so that the controller compares this temperature value with the detection value of the ninth temperature sensor 515, so as to determine whether the current working state of the isolation circulation system 5 can meet the actual working needs.
[0187] The third flow meter 527 is mainly used to detect the flow of the intermediate heat transfer medium circulating in the isolation circulation system 5, and feed back the detection value to the controller so that the controller can grasp the flow of the intermediate heat transfer medium in real time and make relevant adjustments according to actual needs.
[0188] The tenth pressure sensor 529 is mainly used to detect the pressure at the outlet of the main return liquid pipe 521, and feed back the detection value to the controller, so that the controller can use the pressure value to determine whether the liquid pump drive component can work normally, and at the same time compare it with the outlet pressure of the condensing heat exchange pipe 32 of the first heat exchanger 3 to analyze and complete the determination of the working status of the first heat exchanger 3.
[0189] The eleventh temperature sensor 5210 is mainly used to detect the temperature of the intermediate heat-conducting medium that is about to enter the first heat exchanger 3, and to feed back the detection value to the controller, so that the controller can determine the heat release and cooling effect of the intermediate heat-conducting medium based on the detection value and the detection value of the eighth temperature sensor 514, and then determine the working status of the first heat exchanger 3.
[0190] To facilitate the pressure and flow stabilization of the pressure-stabilizing tank 523, this embodiment adds a pressure and flow stabilization component 528 to the pressure-stabilizing tank 523. Specifically, the pressure and flow stabilization component 528 primarily includes a bladder expansion tank and an automatic exhaust valve 516. This component is primarily used to regulate parameters such as the pressure and / or flow rate of the intermediate heat-conducting medium within the pressure-stabilizing tank 523 during the circulation of the intermediate heat-conducting medium by utilizing the bladder expansion tank, the automatic exhaust valve 516, and a large flow diameter to reduce the flow rate, thereby achieving a constant pressure and constant flow operating mode for the intermediate heat-conducting medium.
[0191] As for the remaining auxiliary components of the isolation liquid return module 52 , please refer to the aforementioned cold plate liquid return module 43 , which will not be described in detail here.
[0192] As shown in FIG16 , FIG16 is a schematic diagram of the specific structure of the fluid replenishing tank 53 .
[0193] In addition, considering the loss of the intermediate heat-conducting medium, a liquid replenishing tank 53 is also added in this embodiment. Specifically, a preset amount of intermediate heat-conducting medium is stored in the liquid replenishing tank 53, and the outlet of the liquid replenishing tank 53 is connected to the pressure-surge tank 523. It is mainly used to replenish the intermediate heat-conducting medium in the pressure-surge tank 523 when the amount is reduced, so as to ensure that the flow rate of the intermediate heat-conducting medium in the circulating flow is maintained within the target range. At the same time, in order to facilitate the automatic replenishment of the pressure-surge tank 523 by the intermediate heat-conducting medium in the pressure-surge tank 523, this embodiment also provides an automatic liquid replenishing pump 531 at the bottom of the liquid replenishing tank 53. The automatic liquid replenishing pump 531 is connected to the controller signal. When the water level in the pressure-surge tank 523 is lower than the preset threshold, the controller automatically controls the automatic liquid replenishing pump 531 to operate to achieve automatic liquid replenishment. As for the remaining accessories of the liquid replenishing tank 53, reference can be made to the accessories on the aforementioned temperature-controlled water storage tank 411, which will not be repeated here.
