[0026] Specifically, the working process or working principle of this modular environmental control liquid cooling device is as follows: the device is mainly used for ground liquid cooling of aircraft, providing a ground liquid cooling source, system cleaning, and coolant filling for the onboard environmental control liquid cooling system. The usage process is as follows: Mode 1, refrigeration system working: The vapor compression refrigeration system is composed of four basic components: a refrigeration compressor, a condenser, an evaporator and a throttle valve. These components are connected in sequence by pipes to form a closed system. The refrigerant circulates continuously in the system, changes its state, and exchanges heat with the outside world. After the liquid refrigerant absorbs the heat of the cooled object in the evaporator, it vaporizes into low-temperature, low-pressure steam. It is sucked into the compressor and compressed into high-pressure, high-temperature steam and then discharged into the condenser. In the condenser, it releases heat to the cooling medium and condenses into a high-pressure liquid. It is throttled by the throttle valve to a low-pressure, low-temperature refrigerant and enters the evaporator again to absorb heat and vaporize, thereby achieving the purpose of circulating refrigeration. In this way, the refrigerant completes a refrigeration cycle through the four basic processes of evaporation, compression, condensation, and throttling in the system.

[0027] Mode 2: Cooling / cleaning aircraft liquid cooling pipes When there is no onboard pump as a power source, the onboard environmental control liquid cooling system is connected to the onboard environmental control liquid cooling system for pressurized circulation.

The onboard coolant returns to the environmental control liquid cooling device through the return liquid hose, passes through the four-way ball valve 5, enters the liquid tank 6, is pressurized by the primary pump 4 and the secondary pump 3, and then passes through the one-way valve 2, the flow meter 1, the refrigeration unit 24, the liquid supply temperature sensor 21, the liquid supply pressure sensor 22, the primary filter 20, the secondary filter 19, the liquid supply hose 16 and the ground liquid supply connector 14, and enters the onboard liquid cooling system. In this way, the heat released by the aircraft radar electronic components is absorbed by the circulating coolant, and after multiple cycles of heat exchange, the onboard liquid cooling system is ensured to be within the appropriate operating temperature range.

The onboard coolant can return to the environmental control liquid cooling device through the liquid return hose, pass through the four-way ball valve 5, and be pressurized by the primary pump 4 and the secondary pump 3, and then pass through the one-way valve 2, the flow meter 1, the refrigeration unit 24, the primary filter 20, the secondary filter 19, the liquid supply temperature sensor 21, the liquid supply pressure sensor 22, the liquid supply hose 16 and the ground liquid supply connector 14, and enter the onboard liquid cooling system. In this way, the heat released by the electronic components of the aircraft radar is absorbed by the circulating coolant. After multiple cycles of heat exchange, it is ensured that the onboard liquid cooling system is within the appropriate operating temperature range.

[0029] Mode 3: Add coolant to the machine: Large liquid filling function: After the liquid in the liquid tank 6 is sucked and pressurized by the primary pump 4, the cooling liquid enters the on-board liquid cooling system through the one-way valve 2, the flow meter 1, the primary filter 20, the secondary filter 19, the liquid filling hose 17 and the liquid filling connector 15.

[0030] The power supply frequency of the vacuum pump 7 motor can be controlled through the human-machine interface to change the rotation speed of the vacuum pump 7, so as to realize continuous adjustment of the flow and pressure of the liquid filling.

[0031] Small liquid volume filling function: The environmental control liquid cooling device is provided with a portable filling device, the effective volume of which is designed to be 3.5L. The portable filling device adopts a mechanical pressurization mode, the entire device is made of stainless steel, a liquid level window with an accuracy of 50mL is arranged on the front surface of the device, the device is provided with a pressurization handle to provide a pressurization gas source, and a matched liquid filling rubber tube is used to fill the aircraft with small liquid volume.

[0032] Mode four, device self-circulation: When the environmental control liquid cooling device is self-circulatingly cleaned, the ground liquid supply connector 14 and the ground liquid return connector 13 are connected to the self-circulation assembly, the environmental control liquid cooling device is started, the primary pump 4 and the secondary pump 3 pressurize the cooling liquid after sucking the cooling liquid in the liquid tank 6, and then the cooling liquid returns to the liquid tank 6 through the one-way valve 2, the flow meter 1, the plate heat exchanger, the primary filter 20, the secondary filter 19, the liquid supply temperature sensor 21, the liquid supply pressure sensor 22, the liquid supply hose 16, the ground liquid supply connector 14, the ground liquid return connector 13, the liquid return rubber tube and the four-way valve 5, so that the cooling liquid is circulated, the self-circulation connector is connected between the ground liquid supply connector 14 and the ground liquid return connector 13, the cooling liquid can be circulated and cleaned, the cleanliness of the cooling liquid is maintained, and impurities in the cooling liquid are prevented from entering the aircraft equipment during use of the cooling liquid.
