| Abstract: |
| Firstly, the working principle of the liquid cooling system of airborne electronic equipment at home and abroad is analyzed, that is, under the action of the liquid pump, the cooling liquid enters the cold plate of electronic equipment, takes away the heat of electronic equipment, and then goes through the heat exchanger for cooling treatment. The heat is transferred to the air or fuel, and the cooled cooling liquid flows to the liquid pump for the next cooling cycle. Secondly, it is also analyzed that some airborne electronic equipment is cooled by forced ventilation because its installation position is not suitable for the liquid cooling system, but the heat is finally transferred to the liquid cooling system through the air. Finally, the future of aircraft liquid cooling technology is prospected. The future development trend of liquid cooling system must be the ability of regional fault isolation, and the flow rate of coolant changes dynamically with the heat load, and its compensation loss is also small. |
