The invention relates to the field of unmanned aerial vehicle wing anti-icing and de-icing, in particular to an unmanned aerial vehicle anti-icing and de-icing system and method capable of automatically adjusting the sunward direction by combining a phase change energy storage auxiliary oil tank and a photo-thermal coating. The system comprises a photo-thermal coating, a loop heat pipe system, an icing detection system, an auxiliary oil tank and an automatic sun tracking system. The photo-thermal coating covers the surface of the wing and is used for absorbing sunlight and converting the sunlight into heat energy; the loop heat pipe system is composed of an evaporation section, a compensation chamber and a condensation section which are connected through a pipeline. The automatic sun tracking system is used for detecting the direction angle and the elevation angle of the sun and is in cascade control with the flight system to change the flight angle, so that the flight angle is in the optimal illumination intensity, and the light and heat absorption amount is improved. The phase-change material in the auxiliary fuel tank can store heat on the surface of the wing through the loop heat pipe, and when the surface of the wing is frozen, the loop heat pipe system takes heat from the phase-change material and fuel oil to achieve ice prevention and removal. The power consumption is reduced while the deicing effect is ensured, and the endurance of the unmanned aerial vehicle is ensured.
