AI Technical Summary

Technical Problem

Drones suffer from insufficient heat dissipation when operating at high power, leading to a decline in component performance. Furthermore, traditional heat dissipation methods struggle to balance efficient heat dissipation with waterproofing requirements, and short circuits are particularly likely to occur during flight in rainy weather.

Method used

The heat dissipation frame and air duct cover are made of metal to form a closed heat dissipation cavity. Combined with sealing gaskets and dustproof nets, the air is circulated by a cooling fan to form an efficient heat dissipation path. The sealing gaskets also form a waterproof barrier to ensure that the interior is isolated from the outside.

Benefits of technology

It achieves efficient heat dissipation, prevents moisture infiltration, improves the heat dissipation efficiency and reliability of components, reduces system weight and size, and maintains stable operation of the drone in complex environments.

Abstract

The utility model discloses a cooling system of an unmanned aerial vehicle. The cooling system comprises a cooling frame, an air duct cover plate, a cooling fan and a dustproof net. The heat dissipation frame is made of a metal material and comprises a heat dissipation air duct main body (first heat dissipation fins are arranged on the inner wall and coincide with the air duct cover plate in position) and a peripheral mounting platform; and the top is sealed by a first sealing gasket and the bottom is sealed by a second sealing gasket to form a closed cavity. An air inlet is formed in the front end of the heat dissipation air duct main body; the air duct cover plate is fixed at the top of the frame through a sealing gasket, the upper surface is provided with a heat-conducting contact surface, and the lower surface is provided with second radiating fins to form a radiating path with the first radiating fins. A dustproof net is arranged at an air outlet in the rear end of the heat dissipation frame, and a heat dissipation fan is fixed to an air inlet and drives cold air to be exhausted from the air outlet after heat exchange through the two heat dissipation fins.
