Abstract: An unmanned aerial vehicle (UAV) includes a heat dissipation device, an inertial measurement unit (IMU), and a control module. The heat dissipation device includes an air guiding cover and a heat conduction plate. The air guiding cover includes an air duct configured to guide an airflow, and the heat conduction plate directly constitutes a portion of a sidewall of the air duct. The IMU module is received within the air duct. The control module is located outside the air duct and disposed at a side of the heat conduction plate that faces away from the IMU module. Heat generated by the IMU module is taken away directly by the airflow within the air duct.
