本研究的目的是通过实验研究双补偿室环路热管（DCCLHP）防冰系统的启动和运行特性。环路由不锈钢制成，带有镍芯，工作流体为乙醇。实验的热负荷为 10 W 至 180 W。迎角 (AOA) 为 -10° 至 5°。研究发现：（1）为了获得良好的防冰效果，DCCLHP防冰系统应在飞机遇到过冷水滴云前约10分钟开启； (2)迎角不为0°时，启动过程中出现温度振荡； (3)正迎角可以提高表面温度，从而增强防冰效果。
The objective of this research is to experimentally investigate the start-up and operating characteristics of the Double Compensation Chamber Loop Heat Pipe (DCCLHP) anti-icing system. The loop was made of stainless steel with nickel wick, and the working fluid was ethanol. Experiments were carried out with the heat loads from 10 W to 180 W. The angle of attack (AOA) is from −10° to 5°. It was found that: (1) in order to obtain a good anti-icing result, the DCCLHP anti-icing system should be turned on approximately ten minutes before the aircraft encountered cloud with super-cooled droplets; (2) temperature oscillations happened in the start-up process when the AOA is not 0°; (3) the positive AOA can increase the surface temperature, as a result of which the anti-icing effect could also be enhanced.
