The aircraft fuel oil absorbs a large amount of heat on the ground, and the fuel oil with higher temperature is conveyed to the interlayer between the inner skin and the outer skin of the aircraft wing by the circulating pump to carry out sufficient heat exchange in the flying process, so that the surface temperature of the wing is kept higher than the freezing point, and the wing is prevented from being frozen. And meanwhile, when the fuel temperature of the airplane is reduced to a certain value or the fuel quantity of a fuel tank is too low, the outer skin of the wing is directly heated, so that the deicing device is prevented from losing effectiveness after the fuel temperature is too low. The wing deicing device has high deicing efficiency, and the energy comes from the sensible heat absorbed by fuel oil which occupies higher proportion of the airplane, so that the energy consumption of the deicing device is effectively reduced.
