Thermal management system and thermal management method, and unmanned aerial vehicle applying thermal management system

The present invention discloses an unmanned aerial vehicle comprising a body. The body is provided with an accommodating cavity, an air intake and an air outlet, and the air intake and the air outlet are communicated with the accommodating cavity. The air intake is used for suction of air flow generated by a propeller of the unmanned aerial vehicle, and the air flow can flow out from the air outlet via the accommodating cavity. The present invention also provides a thermal management system and a thermal management method, and an unmanned aerial vehicle applying the thermal management system. Thermal dissipation efficiency of the unmanned aerial vehicle is relatively high.
