According to the unmanned aerial vehicle, a new heat dissipation system is designed, the heat dissipation system can be used for installing a holder, a power source, a circuit board, a chip or a lighting device of the unmanned aerial vehicle, and the heat dissipation system and a rotor wing are correspondingly arranged on the upper side and the lower side of a cantilever crane by setting the position relation between fins on the heat dissipation side of a base of the heat dissipation system and the cantilever crane and the rotor wing; the parts, provided with the fins, of the two longitudinal ends of the base of the heat dissipation system exceed the two sides of the arm frame correspondingly, so that when downward airflow generated by the rotor wings passes through the arm frame, the airflow is divided into two parts to pass through the arm frame, a vortex is formed under the arm frame, the flow speed of the fins located on the two sides of the arm frame can be larger, and the heat dissipation efficiency is improved. And the flow speed of the fins located under the arm frame is smaller, so that the heat can be quickly taken away from the heat dissipation system by utilizing the airflow generated by the rotor wings, the heat dissipation efficiency is improved, the to-be-cooled structure of the unmanned aerial vehicle is cooled more efficiently, and the use safety of the unmanned aerial vehicle is improved.
本发明涉及一种无人机,其设计了新的散热系统,散热系统能够用于安装无人机的云台、电源、电路板、芯片或照明装置等,通过设置散热系统的基座散热侧的翅片与臂架和旋翼的位置关系,使得散热系统和旋翼对应设置于臂架的上下两侧,散热系统的基座的纵向两端具有所述翅片的部分分别超出所述臂架的两侧,使得旋翼产生向下的气流经过臂架时,将分成两部分气流从臂架经过,进而在臂架正下方形成涡旋,能够使得位于臂架两侧的翅片处的流速更大,位于臂架正下方的翅片处的流速更小,这使得能够利用旋翼产生的气流更快的将热量带离散热系统,提高散热效率,进而更高效率的对无人机的待散热结构进行散热,提高无人机的使用安全性。
