Description

[0001] The invention relates to the technical field of liquid cooling systems, and in particular to a refrigeration and cold storage liquid cooling composite environmental control device. Background Art

[0002] With the rapid development of electronic technology and Internet computing power, the scale and performance of electronic products have been improved, and the characteristic size of electronic devices has been drastically reduced from micron level to nano level, and the integration level has increased by 40% to 50% per year. At the same time, instantaneous power consumption is very important in the design and management of electronic equipment. When in a high-load operation state, the instantaneous power consumption will also increase accordingly, which leads to a significant increase in the heat generated by electronic equipment during operation. If the heat cannot be effectively dissipated, it will cause the equipment to overheat, affect performance, and even damage the hardware.

[0003] Designers often use instantaneous power consumption to predict the device's ability to handle power consumption, and design corresponding high-temperature resistant and high-performance electronic products to meet the power requirements at a specific moment, which not only increases production costs, but also affects the safety and reliability of electronic product operation. Traditional heat dissipation equipment is difficult to meet the needs of high peak heat dissipation, so it is particularly important to solve the instantaneous high heat consumption of electronic product heat loads.

[0004] Therefore, it is necessary to provide a refrigeration cold storage liquid cooling composite environmental control equipment, which can store cold when the heat load is low and the standby load is low, and release cold when the instantaneous peak is reached, so as to effectively solve the problem of instantaneous high heat consumption of the heat load of electronic products.

[0043] Example 1

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

[0045] Working process of compression refrigeration system: The compressor 1 in the compression refrigeration system is turned on, and the high-temperature and high-pressure refrigerant gas is discharged into the oil separator 2. The refrigerant gas separated from the compressor lubricating oil enters the condenser 3, and the high-temperature and high-pressure refrigerant gas is condensed into refrigerant liquid, and then enters the liquid storage tank 4. The liquid refrigerant flows through the drying filter 5 and enters the refrigerant branch 1;

[0046] The compression refrigeration system is divided into two paths after passing through the drying filter 5, which are defined as refrigerant branch 1 and refrigerant branch 2 respectively;

[0047] The refrigerant branch 1 includes a turbine flow meter 6, a solenoid valve 7, a thermal expansion valve 8 and a plate heat exchanger 9;

[0048] The refrigerant branch 2 includes a turbine flowmeter 11 , a solenoid valve 12 , a thermal expansion valve 13 and a cold storage and release device 14 .

[0049] After the liquid refrigerant enters the refrigerant branch 1, it flows through the turbine flowmeter 6, the solenoid valve 7, and the thermal expansion valve 8. The thermal expansion valve adjusts the opening according to the evaporation pressure. The liquid refrigerant enters the plate heat exchanger 9 after throttling by the thermal expansion valve 8, evaporates in the plate heat exchanger 9, and then enters the gas-liquid separator 10, and then returns to the compressor 1, and this reciprocating cycle is repeated.

[0050] It is worth mentioning that, during this cycle, the solenoid valve 1 7 is in the open state and the solenoid valve 2 12 is in the closed state.

[0051] Working process of the liquid supply system: After the compression refrigeration system is started, the liquid supply system works, the water pump 16 is turned on, and the coolant in the water tank 24 is pumped out, and distributed into two paths through the electric three-way regulating valve 17, which are defined as coolant branch 1 and coolant branch 2 respectively;

[0052] Among them, the coolant branch one includes a turbine flowmeter four 22, a ball valve two 21 and a cold storage and cooling device 14 connected through a pipeline; the coolant branch two includes a turbine flowmeter three 18 and a plate heat exchanger 9 flowing through a pipeline.

[0053] For the coolant branch 1: the coolant flows through the turbine flowmeter 4 22 and the ball valve 2 21 in the coolant branch 1 and enters the cold storage and cooling device 14 for cooling and heat exchange, and then continues to flow out to the three-way connection 19;

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

[0055] The liquid cooling medium flowing through the coolant branch 1 and the coolant branch 2 merges at the three-way connection 19, enters the load 23, absorbs the load heat at the load 23, and then flows out into the water tank 24, thereby completing a working cycle.

[0056] It must be said that in the ultra-high load working mode, the cooling capacity of the 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 working process of the refrigeration cold storage liquid cooling composite environmental control equipment under the high heat load working mode, as shown in the attached 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 in Example 1, which will not be described in detail here.

[0060] Working process of the liquid supply system: After the compression refrigeration system is started, the liquid supply system works, the water pump 16 is turned on, and the coolant in the water tank 24 is pumped out. After being distributed and regulated by the electric three-way regulating valve 17, all the coolant enters the coolant branch two and is not distributed to the coolant branch one. After passing through the turbine flowmeter three 18, the coolant enters the plate heat exchanger 9 for heat exchange, and then continues to flow out to the three-way connection 19, and enters the load 23 through the three-way connection 19. After absorbing the load heat at the load 23, it flows out into the water tank 24, thereby completing a working cycle.

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

[0062] Example 3

[0063] This embodiment provides the working process of the refrigeration cold storage liquid cooling composite environmental control equipment in the low heat load working mode, as shown in the attached manual. Figure 1 , 4 As shown, the details are as follows:

[0064] Working process of compression refrigeration system: The compressor 1 in the compression refrigeration system is turned on, and the high-temperature and high-pressure refrigerant gas is discharged into the oil separator 2. The refrigerant gas separated from the compressor lubricating oil enters the condenser 3, condenses the high-temperature and high-pressure refrigerant into liquid refrigerant, and then enters the liquid storage tank 4. The liquid refrigerant flows through the drying filter 5 and flows through the refrigerant branch 1 and the refrigerant branch 2 respectively;

[0065] Among them, the refrigerant branch 1 includes a turbine flowmeter 1 6, a solenoid valve 1 7, a thermal expansion valve 1 8 and a plate heat exchanger 9; the refrigerant branch 2 includes a turbine flowmeter 2 11, a solenoid valve 2 12, a thermal expansion valve 2 13 and a cold storage and cooling device 14;

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

[0067] For the refrigerant branch 2: the liquid refrigerant passes through the turbine flowmeter 2 11, the solenoid valve 2 12, the thermal expansion valve 2 13, and enters the cold storage and cooling device 14 for cold storage. After passing through the cold storage and cooling device 14, it passes through the one-way valve 15 and continues to flow out to the gas-liquid separator 10;

[0068] The liquid refrigerant flowing through the refrigerant branch 1 and the refrigerant branch 2 merges and enters the gas-liquid separator 10, and then enters the compressor 1, thereby forming a cycle.

[0069] It is worth mentioning that during this cycle, both the solenoid valve 1 7 and the solenoid valve 2 12 are in the open state.

[0070] The working process of the liquid supply system is consistent with the liquid supply process under the high heat load working mode in Example 2, and can be referred to in Example 2, and will not be described in detail here.

[0071] It must be said that in the low heat load working 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, and the cold capacity of the load 23 is provided by the compression refrigeration system.

[0072] Example 4

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

[0074] Working process of compression refrigeration system: compressor 1 is turned on, high-temperature and high-pressure refrigerant gas is discharged into oil separator 2, refrigerant gas separated from compressor lubricating oil enters condenser 3, high-temperature and high-pressure refrigerant gas is condensed into refrigerant liquid, and then enters liquid storage tank 4, liquid refrigerant flows through drying filter 5, continues to flow through refrigerant branch 2, does not pass through refrigerant branch 1, liquid refrigerant passes through turbine flowmeter 2 11, solenoid valve 2 12, thermal expansion valve 2 13, enters cold storage and cooling device 14 for cold storage, enters gas-liquid separator 10 after passing through cold storage and cooling device 14, and then enters compressor 1, thus forming a cycle.

[0075] It is worth mentioning that, during this cycle, the solenoid valve 1 7 is in a closed state, and the solenoid valve 2 12 is in an open state.

[0076] Working process of the liquid supply system: After the compression refrigeration system is started, the liquid supply system works, the water pump 16 is turned on, and the coolant in the water tank 24 is pumped out, and all of it is distributed to the coolant branch one through the electric three-way regulating valve 17. The coolant enters the cold storage and cooling device 14 through the turbine flowmeter four 22 and the ball valve two 21 in the coolant branch one for cooling and heat exchange, and then continues to flow out to the three-way connection 19, and then enters the load 23, absorbs the load heat at the load 23, and then flows out into the water tank 24, thereby completing a working cycle.

[0077] It must be said that in the standby heat load working mode, the cooling capacity of the load 23 is only provided by the cold storage and cooling 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 manufacturers. Those skilled in the art can fully implement them without further elaboration.

[0079] In conjunction with the contents of Examples 1-4, please refer to the attached Figure 1 , a specific description of the relevant control functions in this application is given:

[0080] 1. Compression refrigeration system, which has energy regulation function and low-temperature refrigeration function. The electronic control unit realizes control by collecting signals from the compression refrigeration system and the liquid supply system.

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

[0082] When the cooling demand of load 23 and cold storage can be met, the sensor signal at the plate exchange outlet is collected to control the opening of the electronic injection valve in the bypass refrigerant branch to bypass the excess cooling capacity to the plate exchange inlet, thereby realizing the cooling energy regulation of the compression refrigeration system. The suction temperature of compressor 1 is too high. In order to protect compressor 1, part of the refrigerant liquid from the liquid storage tank 4 enters the gas-liquid separator 10 through the solenoid valve and capillary of the branch to ensure the suction temperature and pressure of compressor 1.

[0083] 3. Low-temperature start: Use the two valves NRD (pressure differential valve) + KVR (condensing pressure regulating valve) and the electric heater wrapped on the compressor 1 and the liquid reservoir 4 to adjust the condensing pressure. Under low-temperature conditions, the electric heater wrapped on the compressor 1 and the liquid reservoir 4 is turned on to preheat the components. After preheating to a certain temperature, the compressor 1 is turned on. The initial exhaust pressure of the compressor 1 is low, the NRD (pressure differential valve) is opened, and a large amount of refrigerant gas is discharged into the liquid reservoir 4. When the pressure in the liquid reservoir 4 reaches a certain value, the NRD (pressure differential valve) is closed, and the KVR (condensing pressure regulating valves) in the system are opened one by one. The compressor 1 establishes an operating pressure difference, the system operates normally, and the electric heating is turned off.
