Unmanned aerial vehicle and heat dissipation structure

Abstract

A UAV includes a camera assembly, a heat generating device, and a heat dissipation structure including a housing, a heat dissipation device, and heat dissipation fan for providing an air flow into the housing. The housing receives the heat generating device and includes a first air inlet and a first air outlet. The heat dissipation device includes heat dissipation fins disposed in parallel. The first air inlet and the camera assembly are located at a same side of the housing. The camera assembly is disposed at a front portion of the housing. A heat dissipation air channel formed between two adjacent heat dissipation fins includes a second air inlet and a second air outlet that is connected with the first air outlet. The heat dissipation fan includes a third air inlet connected with the first air inlet and a third air outlet connected with the second air inlet.
