| 中文摘要: |
| 首先分析了国内外机载电子设备液冷系统的工作原理，即冷却液在液体泵的作用下，进入电子设备冷板，带走电子设备的热量，再通过热交换器进行降温处理，热量传递到空气或燃油中，降温后的冷却液流向液体泵，进行下一次的冷却循环。其次分析了某些机载电子设备因安装位置不适用液冷系统，则采用强迫通风为其进行冷却，但热量最终经过空气还是传递至液冷系统中。最后对未来飞机的液体冷却技术进行了展望，液冷系统未来的发展趋势一定是有区域故障隔离能力，且冷却液的流量是随着热载荷而动态变化的，其代偿损失也较小。 |
| 英文摘要: |
| 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. |
