The invention provides an anti-gravity heat pipe air-cooled fuel cell stack for an unmanned aerial vehicle and the unmanned aerial vehicle wherein the anti-gravity heat pipe air-cooled fuel cell stack comprises: a fuel cell stack mounted at the top of a fuselage shell of the unmanned aerial vehicle; the anti-gravity heat pipe comprises an evaporator, a steam pipeline, a condenser and a liquid pipeline which are sequentially connected to form a loop, the evaporator is installed between the fuel cells, and the condenser is located below the evaporator and extends out of the machine body shell; the first fan is mounted in the machine body shell and supplies air to the anti-gravity heat pipe; and the second fan is used for supplying air to the fuel battery pack and providing air required by electrochemical reaction. In the operation process of the unmanned aerial vehicle, heat generated by the fuel cell can be transmitted to the condenser through the evaporator and the steam pipeline, the condenser conducts heat exchange through forced convection generated by air supply of the first draught fan in the vehicle body shell and natural convection of external air when the unmanned aerial vehicle operates, and the heat can be effectively dissipated into the air; and heat dissipation of the fuel cell stack is realized.
本发明提供一种用于无人机的反重力热管风冷式燃料电池堆及无人机,其中反重力热管风冷式燃料电池堆包括:燃料电池组,安装在无人机的机身壳体顶部;反重力热管,包括依次连接构成环路的蒸发器、蒸汽管路、冷凝器、以及液体管路,蒸发器安装在燃料电池之间,冷凝器位于蒸发器的下方且延伸至机身壳体外;第一风机,安装在机身壳体内,面对反重力热管送风;第二风机,面对燃料电池组送风,提供电化学反应所需的空气。在无人机运行过程中,燃料电池产生的热量会经蒸发器和蒸汽管路传递至冷凝器,冷凝器利用第一风机在机身壳体内送风产生的强制对流及无人机运行时外界空气的自然对流来进行换热,可有效将热量散发到空气中,实现燃料电池堆的散热。
