UNMANNED AERIAL VEHICLE ELECTRONIC SPEED CONTROLLER HEAT DISSIPATION DEVICE

WIPO Patent Application WO/2017/132805

A1

The present invention relates to a unmanned aerial vehicle electronic speed controller (ESC) heat dissipation device. The device comprises an arm (1), an ESC (2) being provided internally at one end of the arm (1), a rotor being provided at the other end; the present invention further comprises an ESC heat dissipation plate (3), the top surface of the ESC heat dissipation plate (3) being screw fastened to the arm (1), and the bottom surface being adhesively fixed to the ESC (2) by means of thermal adhesive (4); the contact surface between the arm (1) and the ESC heat dissipation plate (3) is provided with at least two heat dissipation holes (5); a groove which is in communication with the heat dissipation holes (5) is provided on the ESC heat dissipation plate (3). In the unmanned aerial vehicle ESC heat dissipation device of the present invention, the ESC (2) is sealedly disposed inside the arm (1) to prevent erosion by pesticide fog; at the same time, heat generated by the ESC (2) is dissipated by the ESC heat dissipation plate (3), and the heat dissipation holes (5) can conduct high-speed airflow generated by the rotor to the ESC heat dissipation plate (3) to be dissipated out both ends of the arm (1), creating effective heat dissipation; the overall structure is simple and low-cost.
