Power supply system for drones

Abstract

This invention provides a power supply system for a drone, comprising a power module, an antenna power supply control module, and a heat dissipation module. The power module provides power to a low-Earth orbit (LEO) satellite antenna mounted on the drone. The antenna power supply control module is located between the power module and the LEO satellite antenna and is electrically connected to both, used to regulate the power output of the power module. The heat dissipation module is mounted on the power module and includes first and second heat dissipation structures. The first heat dissipation structure is located on the power module and passively conducts heat generated on the power module. The second heat dissipation structure is located on the power module and adjacent to the first heat dissipation structure, and actively conducts power generated on the power module.
