The invention discloses a heat dissipation structure for an engine of an unmanned aerial vehicle, which comprises a mounting base, a driving mechanism is arranged in the mounting base, an air inlet mechanism is arranged at the top end of the mounting base, a cooling mechanism is arranged in the driving mechanism, and an exhaust mechanism is arranged at the bottom of the mounting base. The heat dissipation structure has the beneficial effects that when the heat dissipation structure is used, cooling liquid in the liquid storage cavity exchanges heat with the double-head driving motor to cool the double-head driving motor. Meanwhile, the double-head driving motor can synchronously drive the air inlet mechanism and the air draft mechanism to operate, the air inlet mechanism draws external cold air into the driving cavity, and the external cold air is blown downwards by the air conveying blades; by arranging the air inlet funnel, cold air enters the ventilation pipe through the air inlet funnel, and exchanges heat with cooling liquid which is gradually heated in the liquid storage cavity through the cold air in the ventilation pipe until the cold air is pumped out by the air suction mechanism, so that the cooling liquid can keep cooling the engine for a long time.

    本发明公开了一种无人机的发动机用散热结构,包括一个安装座,所述安装座的内部设置有一个驱动机构,所述安装座的顶端设置有一个进气机构,所述驱动机构的内部设置有一个冷却机构,所述安装座的底部设置有一个排风机构,本发明所达到的有益效果是:在使用时,储液腔内部的冷却液会与双头驱动电机进行换热来对其进行冷却,同时双头驱动电机会同步带动进风机构与抽风机构进行运作,进风机构将外部的冷风抽入驱动腔内部,并被输风叶片向下吹动,使得冷风通过进风漏斗进入通风管中,并通过通风管中的冷风与储液腔中逐渐升温的冷却液进行换热,直至被抽风机构抽出,使得冷却液可以保持长时间对发动机进行冷却作业。
