Cooling air path system of unmanned aerial vehicle

Abstract

The invention provides a cooling air path system of an unmanned aerial vehicle. The cooling air path system comprises an airflow source, air guiding holes, an air path and air outlets, wherein the airflow source is generated by rotation of paddles on all vehicle arms, the air guiding holes are formed in the portions, corresponding to paddle tail rotating areas, of the top faces of all the vehicle arms, the air path is a gap channel between the inner wall of a vehicle body and internal modules of the vehicle body, and the air outlets are formed in the position, corresponding to a heating source area, of the bottom of the vehicle body. The airflow source guides airflow into the inner sides of the vehicle arms through the air guiding holes, and the airflow enters the air path, flows through the heating source area and then is exhausted from the air outlets. The cooling air path system of the unmanned aerial vehicle is good in whole vehicle cooling performance and low in noise.

Description

technical field [0001] The invention relates to unmanned aerial vehicle technology, in particular to an unmanned aerial vehicle heat dissipation air duct system. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. When the drone is working, it will generate a lot of heat. If the heat is not dissipated in time, the heat accumulation will affect the normal operation of the drone when it is overheated. Long-term overheating will cause damage to the drone or attenuation of its service life. Therefore, a part for heat dissipation is usually provided on the drone.

AI Technical Summary

Problems solved by technology

[0003] Some heat dissipation components are installed in the existing drones to achieve heat dissipation, but only for some parts to play a partial heat dissipation function, for example, the airflow is introduced into the battery compartment and then exported, only for the battery compartment to dissipate heat. However, there are other components in the drone that also generate a lot of heat, such as motors, chips, etc. The airflow is bound in the battery compartment and cannot dissipate heat from the fuselage as a whole. Therefore, the current cooling components have a limited cooling effect.

[0004] In addition, due to its position, structure and other reasons, the set air guide does not collect enough wind and the heat dissipation effect is not good. Therefore, it is necessary to install a fan in the UAV, relying on the fan to achieve sufficient flow of airflow so that the heat dissipation can achieve the ideal effect. However, the space inside the drone's fuselage is limited, and the setting of the fan leads to a larger fuselage and heavier weight, and the operation of the fan will also generate greater noise.
