This utility model relates to the field of circuit board technology and discloses a circuit board with a built-in heat dissipation and airflow guiding structure. The circuit board includes a circuit board body with a copper heat-conducting strip embedded inside. A heat dissipation base is connected to the front end of the circuit board body, and a guide pipe is connected to the outside of the heat dissipation base. A heat dissipation fin holder is connected to the front end of the guide pipe, and a cooling fan is mounted on the top of the heat dissipation fin holder. A connector is mounted on the left side of the circuit board body, and a CPU module is mounted on the front end of the circuit board body. This utility model, by setting up a heat dissipation and airflow guiding structure, allows heat to be transferred through the heat dissipation base to the guide pipe and heat dissipation fin holder during use. Then, by activating the cooling fan, the heat on the heat dissipation fin holder is dissipated, thus achieving the heat dissipation and airflow guiding function.

The utility model provides an artificial intelligence unmanned aerial vehicle charging device comprising a charger housing, the front and rear sides of the upper part of the charger housing are provided with mounting grooves, the middle part of the charger housing is provided with a rectangular groove, and the left and right sides of the upper part of the charger housing are provided with fixing frames from front to back. The front ends and the rear ends of the two fixing frames are fixed to the charger shell through bolts, nuts and mounting grooves, a fixing bolt is mounted on one side of each fixing frame in a threaded mode, and a purging charging rotary disc assembly is mounted in the charger shell. Through the arrangement of the driven gear, the rotating shaft, the encoder, the driving gear, the motor, the rotating disc, the mounting plate, the air pump, the duckbilled pipe, the electric telescopic rod and the charging head, a charging port of the unmanned aerial vehicle can be blown before charging, and the charging head can be rotated to the lower portion to reduce the dust falling degree after charging is completed.
