The invention relates to an unmanned aerial vehicle thermal management system and an unmanned aerial vehicle, the unmanned aerial vehicle thermal management system comprises a main vehicle body, connecting arms, propellers and cooling fins, and each propeller is supported and connected to the main vehicle body through the corresponding connecting arm. Part or all of the connecting arms are provided with main condensation cavities, the main machine body is provided with evaporation cavities, working media are arranged in the evaporation cavities, the evaporation cavities are communicated with the main condensation cavities to form a heat pipe structure, the evaporation cavities and the power elements are integrally arranged in a sealed mode, and the heating ends of the power elements can be partially or completely immersed in the working media of the evaporation cavities. And the liquid working medium in the evaporation cavity can absorb heat to be changed into a gaseous working medium and enters the main condensation cavity. The cooling fins are arranged on the peripheral side of the main condensation cavity and connected to the connecting arms, so that heat released after the gaseous working medium is liquefied in the main condensation cavity can be transmitted to the cooling fins through the connecting arms. According to the unmanned aerial vehicle thermal management system and the unmanned aerial vehicle, the problems that an existing thermal management system is not high enough in heat dissipation efficiency and too large in occupied space are solved.
本申请涉及一种无人机热管理系统及无人机,无人机热管理系统包括主机体、连接臂、螺旋桨和散热翅片,每一螺旋桨通过对应的连接臂支撑连接于主机体。部分或者全部连接臂设有主冷凝腔,主机体设有蒸发腔,蒸发腔内设有工质,且蒸发腔连通主冷凝腔形成热管结构,蒸发腔与功率元件一体密封设置,功率元件的发热端能够部分或全部浸没在蒸发腔的工质中,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主冷凝腔。散热翅片设于主冷凝腔的外周侧并连接于连接臂,以使气态工质在主冷凝腔内液化之后释放的热量能够通过连接臂传递至散热翅片。本申请提供的无人机热管理系统及无人机,解决了现有的热管理系统散热效率不够高以及占用体积过大的问题。
