Abstract

The invention discloses an unmanned aerial vehicle motor cooling method, which comprises the steps that cooling fins are arranged on the surface of the wall of an unmanned aerial vehicle, and a heat pipe is arranged on the surfaces of the cooling fins and an unmanned aerial vehicle motor shell; the heat of the unmanned aerial vehicle is conducted to the fins on the surfaces of the arms of the unmanned aerial vehicle through the heat pipe connected with the motor shell; and propellers rotate to generate downward air flow, and the air flow passes through the arms of the unmanned aerial vehicle and takes away the heat of the motors through the cooling fins on the surface of the arms of the unmanned aerial vehicle, so that a liquid cooling system is not needed, the overall weight of the unmanned aerial vehicle is reduced, and the flight time of the unmanned aerial vehicle is prolonged. According to the invention, heat is conducted to the arms through the heat pipe, so that electric energyof the unmanned aerial vehicle does not need to be consumed, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for cooling an unmanned aerial vehicle motor. Background technique [0002] The existing CN2017 / 081105 patent has disclosed a method for cooling the UAV motor through liquid cooling. When the motor temperature is higher than the set temperature, the motor liquid cooling system is turned on to cool the motor; the working principle is that the UAV motor Air cooling is generally used for cooling, and the existing patent CN2017 / 081105 uses liquid cooling to take away the heat generated by the motor and reduce the temperature of the motor; [0003] However, the existing patent CN2017 / 081105 adds a liquid cooling system to dissipate heat from the motor. The liquid cooling system greatly increases the weight and energy consumption of the UAV, thereby reducing the flight time of the UAV. To this end, we propose a method for cooling UAV motors.
