The invention relates to the technical field of heat dissipation of multi-rotor unmanned aerial vehicles, in particular to a heat dissipation device and a heat dissipation method for a multi-rotor unmanned aerial vehicle. A plurality of fan heads are installed on the periphery of the machine frame, fan blades on the fan heads rotate to generate lift force to drive the machine frame to move upwards, an air guide pipe is installed in the machine frame, and the machine frame gathers part of airflow generated by the fan heads and enables the gathered airflow to move in the direction of the air guide pipe. The air guide pipe guides part of air generated by the fan head. Generated air flow is guided to the middle through the rack, the guided air flow is redirected through the air guide pipe, the air flow enters the heat dissipation channel to carry away heat generated by a mainboard and a battery, meanwhile, the air flow out of the heat dissipation channel is directly blown away by the air flow generated by the fan head, the heat is prevented from being gathered near the rack, and the heat dissipation efficiency is improved. Meanwhile, part of airflow generated by the fan head is guided by the rack, so that new power consumption articles are prevented from being added.

    本发明涉及多旋翼无人机散热技术领域,具体地说,涉及一种多旋翼无人机散热装置及散热方法。其包括机架,机架的四周安装有若干个风扇头,风扇头上的扇叶旋转产生升力将机架带动向上移动,机架的内部安装有导气管,机架对风扇头产生的部分气流进行聚集,并使聚集的气流向着导气管的方向移动,导气管对风扇头产生的部分气体进行引导。本发明通过机架将产生的气流向中间引导,再通过导气管对引导的气流进行改向,使气流进入到散热通道中将主板、电池产生的热量携带走,同时从散热通道中出来的气流被风扇头产生的气流直接吹走,避免了热量在机架的附近聚集,同时机架将风扇头产生的部分气流进行引导,避免了加入新的耗电物品。
