When the electronics of your drone overheat, it could spell the end of your flight. The folks at DJI thought “well, the propeller is moving a lot of air down, what if we captured just a bit of it and ported it over the hot stuff?”

There is an opening below one of the propellers that channels air into the important bits, and another opening to channel the air out. The whole process is captured by an onboard computer to keep track of the temperature.

Claim 1. “A heat dissipation structure comprising: a housing configured to accommodate a heating element of an aerial vehicle, the housing including: a first air vent configured to guide an airflow into the housing, the airflow including a propeller-generated airflow generated by a propeller of the aerial vehicle during rotation; a second air vent configured to guide the airflow out of the housing; wherein: the housing is located at an end of an arm of the aerial vehicle, away from the propeller in a longitudinal direction of the arm; and a projection of the housing on a plane on which an area of rotation of the propeller lies at least partially overlaps the area of rotation of the propeller.”
