In order to solve the above problem, the electronic governor 20 on the unmanned aerial vehicle 200 is cooled without affecting the aerodynamic performance of the unmanned aerial vehicle 200, as shown in fig. 1 to 5, an unmanned aerial vehicle horn 100 and an unmanned aerial vehicle 200 having the unmanned aerial vehicle horn 100 are provided in the present disclosure. Wherein, unmanned aerial vehicle horn 100 includes horn main part 10 and electronic governor 20. The horn body 10 is provided with a containing cavity formed in the horn body 10, and at least part of the side wall of the containing cavity is formed into a heat dissipation shell 12. The heat dissipation housing 12 extends along the length of the drone arm 100.
