The invention relates to an unmanned aerial vehicle heat management system, an unmanned aerial vehicle and a cooling fin arrangement method, the unmanned aerial vehicle heat management system comprises a main machine body, connecting arms, propellers and cooling fins, part or all of the connecting arms are provided with condensation cavities, the main machine body is provided with evaporation cavities, working media are arranged in the evaporation cavities, the evaporation cavities communicate with the condensation cavities, and the cooling fins are arranged in the condensation cavities; the evaporation cavity is attached to the heating end of the power element, so that the liquid working medium in the evaporation cavity can absorb heat to be changed into a gaseous working medium and enter the condensation cavity. The cooling fins are arranged on the peripheral side of the condensation cavity and connected to the connecting arms. The outer side of each connecting arm is provided with a plurality of cooling fins, the cooling fins are arranged at intervals in the extending direction of the connecting arms, and the cooling area of the cooling fins tends to be increased in the direction from a rotating shaft of the propeller to the main machine body. According to the unmanned aerial vehicle heat management system, the unmanned aerial vehicle and the arrangement method of the heat dissipation fins, the problems that the heat dissipation efficiency of a heat management system is not high enough and the occupied space is too large are solved.

    本申请涉及一种无人机热管理系统、无人机及散热翅片的排布方法,无人机热管理系统包括主机体、连接臂、螺旋桨和散热翅片,部分或者全部连接臂设有冷凝腔,主机体设有蒸发腔,蒸发腔内设有工质,且蒸发腔连通冷凝腔,蒸发腔贴设于功率元件的发热端,以使蒸发腔内的液态工质能够吸热相变为气态工质并进入冷凝腔。散热翅片设于冷凝腔的外周侧并连接于连接臂。每一连接臂的外侧设有多个散热翅片,且多个散热翅片沿着连接臂的延伸方向间隔设置,沿着从螺旋桨转轴至主机体的方向,散热翅片的散热面积呈增大的趋势。本申请提供的无人机热管理系统、无人机及散热翅片的排布方法,解决了热管理系统散热效率不够高以及占用体积过大的问题。
