The invention discloses an unmanned aerial vehicle engine wind power heat dissipation system which comprises an engine, a generator and a fan, and the engine is provided with a plurality of cylinder bodies protruding in the radial direction. The engine, the generator and the fan are sequentially arranged along the central axis of the engine from bottom to top, and the generator and the fan are both in driving connection with the engine. The air conditioner further comprises an upper wind scooper and a lower cover plate, the upper wind scooper comprises a first cover body used for jointly covering the fan and the generator and a plurality of second cover bodies used for correspondingly covering the cylinder bodies, the lower cover plate is arranged at the bottom of the generator, and a heat dissipation cavity for containing the fan and the generator is defined by the lower cover plate and the first cover body. A connecting section for communicating the first cover body with the second cover body is arranged between the first cover body and the second cover body; and the connecting section is provided with a slope flow guide surface which is radially outward and downwards inclined. By optimizing the space arrangement of the engine, the generator and the fan and combining the upper wind scooper and the lower cover plate, efficient drainage heat dissipation is achieved, meanwhile, the heat dissipation cooling problem of the engine and the generator is solved, and heat dissipation is enhanced.
