The utility model discloses a chimney effect-based high-efficiency heat dissipation structure of an electronic speed regulator of an unmanned aerial vehicle, which belongs to the technical field of heat dissipation of electronic speed regulators of unmanned aerial vehicles and comprises an electronic speed regulator and a heat dissipation assembly which are mounted in a wing shell, and the heat dissipation assembly is fixedly connected with the electronic speed regulator. An air inlet hole and an air outlet hole are formed in the top and the bottom of the wing shell correspondingly, and the heat dissipation assembly is located below the propeller at the end of the wing shell; a plurality of chimney channels with the wide upper portions and the narrow lower portions are formed in the heat dissipation assembly, and airflow downwards flows into the chimney channels from the air inlet holes and flows out from the air outlet holes under rotation of the propellers. The unmanned aerial vehicle is better in heat diss
