Description

Technical Field

[0001] This utility model relates to the field of liquid cooling system technology, specifically to a refrigeration and cold storage liquid cooling composite environmental control device. Background Technology

[0002] With the rapid development of electronic technology and internet computing power, and the improvement of the scale and performance of electronic products, the feature size of electronic devices has shrunk dramatically from the micrometer level to the nanometer level, and the integration density is increasing at a rate of 40% to 50% per year. At the same time, instantaneous power consumption is very important in the design and management of electronic devices. When operating under high load, instantaneous power consumption will also increase accordingly, which will lead to a significant increase in the heat generated by electronic devices during operation. If heat dissipation is not effective, it will cause the device to overheat, affecting performance or even damaging the hardware.

[0003] Designers often predict a device's power consumption capability by analyzing instantaneous power consumption and design corresponding high-temperature resistant, high-performance electronic products to meet power demands at specific moments. This not only increases production costs but also compromises the safety and reliability of electronic product operation. Traditional heat dissipation equipment struggles to meet peak heat dissipation demands, making it crucial to address the instantaneous high heat dissipation of electronic products under thermal loads.

[0004] Therefore, there is a need for a combined cooling, cold storage, and liquid cooling environmental control device that stores cold under low heat load and standby load conditions, and releases cold under instantaneous peak conditions, which can effectively solve the problem of instantaneous high heat consumption of electronic products under heat load.

[0016] Furthermore, it also includes four operating modes: ultra-high load operating mode, high heat load operating mode, low heat load operating mode, and standby heat load operating mode.

[0017] Furthermore, in the ultra-high load operating mode, the first solenoid valve is in the open state, the second solenoid valve is in the closed state, and the refrigerant liquid only flows through the first refrigerant branch; the electric three-way regulating valve distributes the working fluid of the coolant to the first and second coolant branches.

[0018] Furthermore, under high heat load operating mode, solenoid valve one is in the open state, solenoid valve two is in the closed state, and refrigerant liquid only flows through refrigerant branch one; the electric three-way regulating valve distributes all the coolant working fluid to coolant branch two.

[0019] Furthermore, in the low heat load operating mode, both solenoid valve one and solenoid valve two are in the open state, and refrigerant liquid is simultaneously distributed to refrigerant branch one and refrigerant branch two; the electric three-way regulating valve distributes all the coolant working fluid to coolant branch two.

The first valve port of the electric three-way regulating valve 17 is connected to the water pump 16 through a pipeline. The second and third valve ports of the electric three-way regulating valve 17 are respectively connected to the coolant branch 1 and the coolant branch 2 through pipelines.

[0039] The coolant branch includes a turbine flow meter 22, a ball valve 21, a cold storage and release device 14 and a ball valve 20 connected in series. The turbine flow meter 22 is connected to the second valve port of the electric three-way regulating valve 17, and the ball valve 20 is connected to the three-way connection 19.

[0040] The second coolant branch includes a turbine flow meter 18 and a plate heat exchanger 9. The turbine flow meter 18 is connected to the three-valve port of the electric three-way regulating valve 17, and the plate heat exchanger 9 is connected to the three-way connection 19.

[0041] The compression refrigeration system S1 and the liquid supply system S2 are connected through the plate heat exchanger 9 and the cold storage and release device 14.

[0042] The refrigeration and cold storage combined environmental control equipment has four operating modes: ultra-high load operating mode, high heat load operating mode, low heat load operating mode, and standby heat load operating mode. The operating process of the refrigeration and cold storage load control system corresponding to different modes is shown in Examples 1-4, as detailed below:

[0043] Example 1

[0044] This embodiment provides the operating process of a refrigeration, cold storage, and liquid cooling composite environmental control equipment under ultra-high load operating mode, as shown in the attached instruction manual. Figure 1 , 2 As shown, the details are as follows:

[0045] Working process of the compression refrigeration system: When the compressor 1 in the compression refrigeration system is turned on, the high temperature and high pressure refrigerant gas is discharged into the oil separator 2. The refrigerant gas that separates the compressor lubricating oil enters the condenser 3, where the high temperature and high pressure refrigerant gas is condensed into refrigerant liquid, and then enters the liquid receiver 4. After the liquid refrigerant flows through the dryer filter 5, it enters the refrigerant branch line 1.

[0046] The compression refrigeration system is divided into two paths after passing through the dryer filter 5, which are defined as refrigerant branch one and refrigerant branch two, respectively.

[0047] The refrigerant branch includes a turbine flow meter 6, a solenoid valve 7, a thermostatic expansion valve 8, and a plate heat exchanger 9;

[0048] The second refrigerant branch includes a turbine flow meter 11, a solenoid valve 12, a thermostatic expansion valve 13, and a cold storage and release device 14.

[0049] After the liquid refrigerant enters the refrigerant branch, it flows through the turbine flow meter 6, the solenoid valve 7, and the thermostatic expansion valve 8. The thermostatic expansion valve adjusts its opening according to the evaporation pressure. After being throttled by the thermostatic expansion valve 8, the liquid refrigerant enters the plate heat exchanger 9. After evaporating in the plate heat exchanger 9, it enters the gas-liquid separator 10 and then returns to the compressor 1, thus repeating the cycle.

[0050] It is worth mentioning that during this cyclical workflow, solenoid valve 7 is in the open state and solenoid valve 12 is in the closed state.

[0051] The working process of the liquid supply system is as follows: After the compression refrigeration system is started, the liquid supply system works. The water pump 16 is turned on to pump out the coolant working fluid in the water tank 24. The coolant is then distributed into two paths through the electric three-way regulating valve 17, which are defined as coolant branch one and coolant branch two, respectively.

[0052] The first coolant branch includes a turbine flow meter 22, a ball valve 21, and a cold storage and release device 14 connected by a pipeline; the second coolant branch includes a turbine flow meter 18 and a plate heat exchanger 9 connected by a pipeline.

[0053] For coolant branch 1: the coolant working fluid flows through the turbine flow meter 4 22 and ball valve 21 in coolant branch 1 and enters the cold storage and heat release device 14 for cold release and heat exchange, and then continues to flow out to the three-way connection 19.

[0054] For coolant branch line 2: the coolant working fluid enters the plate heat exchanger 9 through the turbine flow meter 3 18 in coolant branch line 2 for heat exchange, and then continues to flow out to the three-way connection 19.

[0055] The liquid coolant flowing through coolant branch one and coolant branch two converges at the tee connection 19 and enters the load 23. After absorbing the load heat at the load 23, it flows out into the water tank 24, thus completing one working cycle.

[0056] It must be said that in the ultra-high load working mode, the cooling capacity of load 23 is provided by the compression refrigeration system and the cold storage and release device 14.

[0057] Example 2

[0058] This embodiment provides the operating process of a combined refrigeration, cold storage, and liquid cooling environmental control device under high heat load operating mode, as shown in the attached instruction manual. Figure 1 , 3 As shown, the details are as follows:

[0059] The working process of the compression refrigeration system is the same as that of the ultra-high load working mode, and can be referred to Example 1, which will not be elaborated further here.

[0060] Liquid supply system workflow: After the compression refrigeration system is started, the liquid supply system operates. Water pump 16 is turned on, pumping out the coolant working fluid in water tank 24. Through the electric three-way regulating valve 17, the coolant working fluid is distributed and regulated, so that all the coolant working fluid enters the second coolant branch and is not distributed to the first coolant branch. After passing through the turbine flow meter 3 18, the coolant working fluid enters the plate heat exchanger 9 for heat exchange, and then continues to flow out to the three-way connection 19. Through the three-way connection 19, it enters the load 23, absorbs the load heat at the load 23, and then flows out into the water tank 24, thus completing one working cycle.

[0061] It must be said that under high heat load operating mode, the cooling capacity of load 23 is provided solely by the compression refrigeration system.

[0062] Example 3

[0063] This embodiment provides the operating process of a refrigeration, cold storage, and liquid cooling combined environmental control device under low heat load operating mode, as shown in the attached instruction manual. Figure 1 , 4 As shown, the details are as follows:

[0064] Working process of the compression refrigeration system: When the compressor 1 in the compression refrigeration system is turned on, the high temperature and high pressure refrigerant gas is discharged into the oil separator 2. The refrigerant gas that separates the compressor lubricating oil enters the condenser 3, where it is condensed into high temperature and high pressure refrigerant liquid, and then enters the liquid receiver 4. The liquid refrigerant flows through the dryer filter 5 and flows through refrigerant branch one and refrigerant branch two respectively.

[0065] Among them, refrigerant branch one includes turbine flow meter one 6, solenoid valve one 7, thermostatic expansion valve one 8 and plate heat exchanger 9; refrigerant branch two includes turbine flow meter two 11, solenoid valve two 12, thermostatic expansion valve two 13 and cold storage and release device 14.

[0066] For refrigerant branch 1: Liquid refrigerant passes through turbine flow meter 6, solenoid valve 7, and thermal expansion valve 8. Thermal expansion valve 8 adjusts its opening according to the evaporation pressure. After being throttled by thermal expansion valve 8, liquid refrigerant enters plate heat exchanger 9. After evaporation and heat exchange in plate heat exchanger 9, it continues to flow out to gas-liquid separator 10.

[0067] For refrigerant branch 2: Liquid refrigerant enters the cold storage and release device 14 through turbine flow meter 21, solenoid valve 22, and thermal expansion valve 23 for cold storage and release. After passing through the cold storage and release device 14, it passes through one-way valve 15 and continues to flow out to gas-liquid separator 10.

[0068] The liquid refrigerant flowing through refrigerant branch one and refrigerant branch two merges and enters the gas-liquid separator 10, and then enters the compressor 1, thus forming a cycle.

[0069] It is worth mentioning that during this cyclical workflow, both solenoid valve 7 and solenoid valve 12 are in the open state.

[0070] The liquid supply system's workflow is consistent with the liquid supply process under the high heat load working mode in Example 2, and can be referred to Example 2. It will not be elaborated further here.

[0071] It must be said that in the low heat load operating mode, the compression refrigeration system not only stores cold for the cold storage and release device 14, but also performs heat exchange for the load 23. The cooling capacity of the load 23 is provided by the compression refrigeration system.

[0072] Example 4

[0073] This embodiment provides the operating process of a refrigeration, cold storage, and liquid cooling composite environmental control device under standby heat load operating mode, as shown in the attached instruction manual. Figure 1 , 5 As shown, the details are as follows:

[0074] The working process of the compression refrigeration system is as follows: When the compressor 1 is turned on, the high-temperature and high-pressure refrigerant gas is discharged into the oil separator 2. The refrigerant gas that has separated from the compressor lubricating oil enters the condenser 3, where the high-temperature and high-pressure refrigerant gas is condensed into refrigerant liquid, and then enters the liquid receiver 4. The liquid refrigerant flows through the dryer filter 5 and continues to flow through the second refrigerant branch, bypassing the first refrigerant branch. After passing through the turbine flow meter 11, the solenoid valve 12, and the thermostatic expansion valve 13, the liquid refrigerant enters the cold storage and release device 14 for cold storage. After passing through the cold storage and release device 14, it enters the gas-liquid separator 10 and then enters the compressor 1, thus forming a cycle.

[0075] It is worth mentioning that during this cyclical workflow, solenoid valve 7 is in the closed state and solenoid valve 12 is in the open state.

[0076] Liquid supply system workflow: After the compression refrigeration system is started, the liquid supply system works. The water pump 16 is turned on, pumping out the coolant working fluid in the water tank 24. The coolant working fluid is distributed to the first coolant branch through the electric three-way regulating valve 17. The coolant working fluid enters the cold storage and heat release device 14 through the turbine flow meter 22 and ball valve 21 in the first coolant branch for heat release and heat exchange. It continues to flow out to the three-way connection 19, and then enters the load 23. After absorbing the load heat at the load 23, it flows out again into the water tank 24, thus completing one working cycle.

[0077] It must be said that in the standby heat load mode, the cooling capacity of load 23 is provided only by the cold storage and release device 14.

[0078] The structures involved in Examples 1-4 are all existing technologies, and their supporting hydraulic systems and pipelines can also be provided by the manufacturer. Those skilled in the art can fully implement them, so there is no need to elaborate.

[0079] Please refer to the appendix of the instruction manual for details in conjunction with the content of Examples 1-4. Figure 1 The following is a detailed description of the relevant control functions in this application:

[0080] 1. The compression refrigeration system has energy regulation and low-temperature refrigeration functions. The electronic control unit controls the system by collecting signals from the compression refrigeration system and the liquid supply system.

[0081] 2. Energy regulation function of the compression refrigeration system: The regulation of the compression refrigeration system is to respond to the regulation of the liquid supply system. It is achieved by collecting the liquid supply temperature at the inlet of load 23. Based on the temperature difference between the set liquid supply temperature t0 and the liquid supply temperature T, the opening of solenoid valve 7 in refrigerant branch 1 and solenoid valve 12 in refrigerant branch 2 are adjusted.

[0082] When the cooling capacity requirements of load 23 and cold storage are met, the opening of the electronic injection valve in the bypass refrigerant branch is controlled by collecting sensor signals located at the plate heat exchanger outlet to bypass excess cooling capacity to the plate heat exchanger inlet, thereby achieving cooling capacity regulation of the compression refrigeration system. If the suction temperature of compressor 1 is too high, to protect compressor 1, a portion of the refrigerant liquid from receiver 4 enters the gas-liquid separator 10 through the solenoid valve and capillary tube of the branch, ensuring the suction temperature and pressure of compressor 1.

[0083] 3. Low-Temperature Start-up: The condensing pressure is regulated using two valves: the NRD (differential pressure valve) and the KVR (condensing pressure regulating valve), along with the electric heaters covering compressor 1 and receiver 4. Under low-temperature conditions, the electric heaters covering compressor 1 and receiver 4 are activated to preheat the components. After preheating to a certain temperature, compressor 1 starts. Initially, the discharge pressure of compressor 1 is low, and the NRD (differential pressure valve) opens, releasing a large amount of refrigerant gas into receiver 4. When the pressure inside receiver 4 reaches a certain value, the NRD (differential pressure valve) closes, and the KVRs in the system open one by one. Compressor 1 establishes an operating pressure differential, the system operates normally, and the electric heaters are turned off.
