Description

Technical Field

[0001] The utility model relates to a liquid cooling liquid supply system, in particular to a multi-way adjustable liquid supply system for a liquid cooling device. Background Art

[0002] With the improvement of the technological content of aircraft technology, the application of a large number of advanced automatic electronic control systems all require various electronic devices to work in combination. Before the actual use of various electronic devices, various tests are also required. During the test, a large amount of heat will be generated by the electronic components themselves. If these heats cannot be taken away in time, it will cause the local area temperature of the electronic device components to be too high, thus affecting the normal operation of the electronic device. Especially for products related to the military industry, in order to ensure that the component products meet the requirements of design and reliability, etc., prior tests and tests are even more essential.

[0003] Among various electronic devices, for example, the radar, which is an important new part on the aircraft, belongs to high-power electronic devices, and the heat flux density of its heating elements will be very large. Therefore, the cooling by traditional forced air cooling can no longer meet the heat dissipation requirements of electronic devices; although the method of introducing liquid fluid cooling can solve the limitations of the existing electronic device thermal environment, the existing liquid cooling liquid supply guarantee equipment for providing liquid cooling effect also has many deficiencies such as large equipment size, inability to access the laboratory site, limited guarantee, and single interface, etc. Therefore, it will also cause many inconveniences during experimental tests. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a multi-way adjustable liquid supply system for a liquid cooling device, which has the characteristics of miniaturization, more flexible and convenient, and at the same time can also provide multi-way independent circulating liquid supply cooling and heat dissipation effects for electronic device cooling, with strong versatility and better reliability.

[0005] The utility model provides the following technical solutions:

[0006] A multi-way adjustable liquid supply system for a liquid cooling device includes a trailer frame with casters. A sheet metal frame is surrounded on the trailer frame. The sheet metal frame is divided into a liquid cooling space and a liquid supply space by a partition. A refrigeration cycle liquid cooling temperature control system is arranged in the liquid cooling space, and a multi-way independent liquid supply system communicated with a liquid storage tank is arranged in the liquid supply space. Each liquid supply system can independently transport anti-freeze coolant to the aircraft electronic equipment compartment, and receive the anti-freeze coolant that has absorbed heat and communicate it to the liquid storage tank to realize the circulation of the anti-freeze coolant and the uniform heat of the anti-freeze coolant, and the refrigeration cycle liquid cooling temperature control system is used to realize the cooling cycle of the anti-freeze coolant in the liquid storage tank;

[0007] Thus, before the test is required, the unit can be moved to the working position, and the aircraft equipment compartment and the liquid supply system can be connected through pipelines. When multiple groups of aircraft equipment compartments need to be tested, one-to-one corresponding connections can be made with the liquid supply system. After the connection, the liquid supply of each route can be independently carried out to meet the circulating cooling of different flow rate requirements of the electronic component equipment to be tested at different workstations. At the same time, since the equipment is installed on a trailer with casters, therefore, as the liquid supply system of the liquid cooling supply guarantee equipment, it can be conveniently moved and quickly adjusted in position, with better reliability and versatility. At the same time, the miniaturized setting is more flexible and convenient.

[0008] Preferably, the refrigeration cycle liquid cooling temperature control system includes a condenser, a fan, a compressor, an expansion valve and a plate heat exchanger. The plate heat exchanger has a coolant inlet and a coolant outlet for communicating with the liquid storage tank. The circulation pump is used to pump out the antifreeze coolant from the liquid storage tank to enter the coolant inlet, and pump out the antifreeze coolant that has been cooled by heat exchange with the refrigerant in the plate heat exchanger from the coolant outlet to circulate into the liquid storage tank. An air inlet net plate is arranged on the side of the sheet metal frame, and a fan is also arranged on its top. The condenser is arranged on one side of the air inlet net plate, and is used to exchange heat with the air entering from the air inlet net plate after receiving the high-temperature and high-pressure gaseous refrigerant output by the compressor to form a medium-temperature and high-pressure liquid refrigerant. The fan is used to suck out the air after heat exchange with the condenser outside the sheet metal frame. The expansion valve is used to receive the medium-temperature and high-pressure liquid refrigerant output by the condenser to form a low-temperature and low-pressure liquid refrigerant and enter the plate heat exchanger. The plate heat exchanger is used to exchange heat between the low-temperature and low-pressure liquid refrigerant and the antifreeze coolant, and is connected to the compressor to input the formed low-temperature and low-pressure gaseous refrigerant into the compressor.

[0009] Preferably, two sets of refrigeration cycle liquid cooling temperature control systems are arranged in the liquid cooling space to improve the liquid cooling efficiency. The two sets of refrigeration cycle liquid cooling temperature control systems are respectively the refrigeration cycle liquid cooling temperature control system one and the refrigeration cycle liquid cooling temperature control system two. The plate heat exchanger has a refrigerant inlet one and a refrigerant outlet one. The refrigerant inlet one and the refrigerant outlet one are connected to the refrigeration cycle liquid cooling temperature control system one to realize the circulation of the refrigerant in the refrigeration cycle liquid cooling temperature control system one. The plate heat exchanger also has a refrigerant inlet two and a refrigerant outlet two. The refrigerant inlet two and the refrigerant outlet two are connected to the refrigeration cycle liquid cooling temperature control system two to realize the circulation of the refrigerant in the refrigeration cycle liquid cooling temperature control system two.

[0010] Thus, because the plate heat exchanger is used to realize the combined heat exchange of two sets of refrigeration cycle liquid cooling temperature control systems, the equipment can be simplified to meet the requirements of miniaturized design. Since the plate heat exchanger is a combination of plate structures, a set of plate heat exchangers can form multiple independent heat exchange channels. This is the prior art and will not be elaborated here.

[0011] Preferably, the refrigeration cycle liquid cooling temperature control system further includes a gas-liquid separator, which is arranged on the pipeline between the plate heat exchanger and the compressor to separate the refrigerant into gas and liquid, ensuring that the refrigerant entering the compressor is always in a gaseous state and avoiding damage to the compressor.

[0012] Preferably, a liquid level sensor and a temperature sensor are installed on the liquid storage tank. The liquid level sensor is used to control the liquid supply of the liquid replenishing tank connected to the liquid storage tank, and the temperature sensor is used to detect the liquid temperature in the liquid storage tank to control the antifreeze coolant to enter the refrigeration cycle liquid cooling temperature control system for cooling.

[0013] Preferably, the multi-channel liquid supply system is arranged side by side horizontally in the sheet metal frame. Each multi-channel liquid supply system includes a set of liquid supply pumps, as well as an inlet flange and an outlet flange installed on the sheet metal frame. The inlet flange and the outlet flange are connected to the liquid storage tank through a liquid supply pipeline, and the antifreeze coolant in each multi-channel liquid supply system is circulated under the drive of the liquid supply pump.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1) Through the multi-channel adjustable and precise liquid supply control design in the present utility model, that is, a set of liquid supply pumps are designed for each multi-channel liquid supply system, specifically a booster water pump can be used, and a multi-channel liquid supply and return interface design is adopted. Through the frequency conversion control of the liquid supply pump, the circulating cooling of different flow rate requirements of the electronic component devices to be tested at different workstations can be realized.

[0016] 2) Before the test is required, the trailer frame is moved to the working position, and the aircraft equipment cabin and the liquid supply system are connected through pipelines. When multiple tests of the aircraft equipment cabin are required, they can be connected one-to-one with the liquid supply system. After connection, the liquid supply of each route can be independently carried out, meeting the circulating cooling of different flow rate requirements of the electronic component devices to be tested at different workstations. At the same time, since the equipment is installed on the trailer frame with casters, therefore, as the liquid supply system of the liquid cooling liquid supply guarantee equipment, it can be conveniently moved and quickly adjusted in position, with better reliability and versatility, and the miniaturized setting is also more flexible and convenient.

[0023] As Figures 1-3 shown, a multi-way adjustable liquid supply system 9 for a liquid cooling device, in this embodiment, includes a trailer frame 2 with casters 1. A sheet metal frame 3 is surrounded on the trailer frame 2. The sheet metal frame 3 is divided into a liquid cooling space 5 and a liquid supply space 6 by a partition 4. A refrigeration cycle liquid cooling temperature control system 8 is arranged in the liquid cooling space 5, and a multi-way independent liquid supply system 9 communicated with a liquid storage tank 7 is arranged in the liquid supply space 6. Each liquid supply system 9 can independently transport anti-freeze coolant to the aircraft electronic equipment compartment, and receive the anti-freeze coolant that has absorbed heat and communicate it to the liquid storage tank 7 to realize the circulation of the anti-freeze coolant and evenly distribute the heat of the anti-freeze coolant. The refrigeration cycle liquid cooling temperature control system 8 is used to realize the cooling cycle of the anti-freeze coolant in the liquid storage tank 7;

[0024] Thus, before the test is needed, the trailer frame 2 can be moved to the working position, and the aircraft equipment compartment and the liquid supply system 9 are connected through pipelines. When multiple groups of tests on the aircraft equipment compartment are needed, one-to-one corresponding connections can be made with the liquid supply system 9. After connection, the liquid supply of each path can be independently carried out, meeting the circulating cooling requirements of different flow rates of the electronic component equipment to be tested at different workstations. At the same time, since the equipment is installed on the trailer frame 2 with casters 1, therefore, as the liquid supply system 9 of the liquid cooling supply guarantee equipment, it can be conveniently moved and quickly positioned, with better reliability and versatility. At the same time, the miniaturized setting is also more flexible and convenient.

[0025] The refrigeration cycle liquid cooling temperature control system 8 includes a condenser 81, a fan 82, a compressor 83, an expansion valve 84, and a plate heat exchanger 85. The plate heat exchanger 85 has a coolant inlet and a coolant outlet for communicating with the liquid storage tank 7. A circulation pump 86 is used to pump out the antifreeze coolant from the liquid storage tank 7 to enter the coolant inlet, and pump out the antifreeze coolant that has been heat-exchanged and cooled with the refrigerant in the plate heat exchanger 85 from the coolant outlet to circulate into the liquid storage tank 7. An air inlet net plate 10 is arranged on the side of the sheet metal frame 3, and a fan 82 is also arranged on its top. The condenser 81 is arranged on one side of the air inlet net plate 10, and is used to exchange heat with the air entering from the air inlet net plate 10 after receiving the high-temperature and high-pressure gaseous refrigerant output by the compressor 83 to form a medium-temperature and high-pressure liquid refrigerant. The fan 82 is used to suck out the air after heat-exchanging with the condenser 81 outside the sheet metal frame 3. The expansion valve 84 is used to receive the medium-temperature and high-pressure liquid refrigerant output by the condenser 81 to form a low-temperature and low-pressure liquid refrigerant and enter the plate heat exchanger 85. The plate heat exchanger 85 is used to exchange heat between the low-temperature and low-pressure liquid refrigerant and the antifreeze coolant, and is connected to the compressor 83 to input the formed low-temperature and low-pressure gaseous refrigerant into the compressor 83.

[0026] Two sets of refrigeration cycle liquid cooling temperature control systems 8 are arranged in the liquid cooling space 5 to improve the liquid cooling efficiency. The two sets of refrigeration cycle liquid cooling temperature control systems 8 are respectively the refrigeration cycle liquid cooling temperature control system 8 one and the refrigeration cycle liquid cooling temperature control system 8 two. The plate heat exchanger 85 has a refrigerant inlet one and a refrigerant outlet one. The refrigerant inlet one and the refrigerant outlet one are connected to the refrigeration cycle liquid cooling temperature control system 8 one to realize the circulation of the refrigerant in the refrigeration cycle liquid cooling temperature control system 8 one. The plate heat exchanger 85 also has a refrigerant inlet two and a refrigerant outlet two. The refrigerant inlet two and the refrigerant outlet two are connected to the refrigeration cycle liquid cooling temperature control system 8 two to realize the circulation of the refrigerant in the refrigeration cycle liquid cooling temperature control system 8 two.

[0027] So far, because the plate heat exchanger 85 is adopted to realize the combined heat exchange of the two sets of refrigeration cycle liquid cooling temperature control systems 8, the equipment can be simplified to meet the requirements of miniaturization design. Since the plate heat exchanger 85 is a combination of plate structures, one set of plate heat exchangers 85 can form multiple independent heat exchange channels. This is the prior art and will not be elaborated here.

[0028] The refrigeration cycle liquid cooling temperature control system 8 further includes a gas-liquid separator 87. The gas-liquid separator 87 is arranged on the pipeline between the plate heat exchanger 85 and the compressor 83 to separate the gas and liquid of the refrigerant, ensuring that the refrigerant entering the compressor 83 is always gaseous and avoiding damage to the compressor 83.

[0029] A liquid level sensor 71 and a temperature sensor 72 are installed on the liquid storage tank 7. The liquid level sensor 71 is used to control the liquid supply of the liquid replenishing tank 11 connected to the liquid storage tank 7, and the temperature sensor 72 is used to detect the liquid temperature in the liquid storage tank 7 to control the antifreeze coolant to enter the refrigeration cycle liquid cooling temperature control system 8 for cooling down.

[0030] The three-way liquid supply system 9 is arranged side by side in the transverse direction within the sheet metal frame 3. Each three-way liquid supply system 9 includes a set of liquid supply pumps 94, and an inlet flange 91 and an outlet flange 92 installed on the sheet metal frame 3. The inlet flange 91 and the outlet flange 92 are connected to the liquid storage tank 7 through a liquid supply pipeline 93, and the antifreeze coolant in each three-way liquid supply system 9 is circulated under the drive of the liquid supply pump 94.

[0031] The working principle of the present utility model is as follows: Before the test needs to be carried out, the unit can be moved to the working position, and the aircraft equipment compartment and the liquid supply system 9 are connected through pipelines. When multiple tests on the aircraft equipment compartment are required, one-to-one corresponding connections can be made with the liquid supply system 9. After the connection, the liquid supply of each route can be carried out independently, meeting the circulating cooling requirements of different flow rates for the electronic component devices to be tested at different workstations. At the same time, since the equipment is installed on the trailer frame 2 with casters 1, therefore, as the liquid cooling liquid supply guarantee equipment, the liquid supply system 9 can be conveniently moved and quickly adjusted in position, with better reliability and versatility. At the same time, the miniaturized setting is more flexible and convenient.
