[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figure 1-4 An electric driver for a drone includes a housing 1. The top of the housing 1 is provided with an encapsulation groove 2, and a circuit board 6 is installed on the inner wall of the bottom of the encapsulation groove 2. The top of the outer walls at both ends of the housing 1 are provided with equally spaced connection grooves 3, and the circuit board 6 is provided with connection pins 7 at the center of the connection grooves 3. Heat dissipation components 5 are installed on the top outer walls on both sides of the housing 1. When a semiconductor cooling chip 10 is activated, the semiconductor cooling chip 10 absorbs and releases heat on one side to reduce the temperature of the driver chip 8. The heat conduction plate 13 and the heat sink 13 cooperate to transfer heat to the ventilation hole 14 to facilitate heat dissipation, ensure the efficiency of the driver chip 8, and prevent high temperature from affecting the driver chip 8.

[0025] Two mounting holes 4 are provided at both ends of the outer casing 1, and an encapsulation layer 15 is cast on the outer casing 1 at the encapsulation groove 2. Example

[0026] Reference Figure 2-4 The heat dissipation assembly 5 includes a mounting plate 16 slidably connected to the outer walls of both sides of the housing 1, an air inlet 17 equidistantly opened on the mounting plate 16 at the top of the housing 1, and a bracket 18 equidistantly installed on the inner outer wall of the mounting plate 16.

[0027] A driver chip 8 is soldered to the top outer wall of the circuit board 6, and an integrated temperature sensor 9 is attached to the top outer wall of the driver chip 8. The encapsulation layer 15 in the housing 1 fixes the driver chip 8 in the housing 1. The heat of the driver chip 8 is transferred through the semiconductor cooling chip 10, the heat conduction plate 12 and the heat sink 13 to increase the heat dissipation area.

[0028] A heat-conducting plate 12 is installed on the inner wall of the bottom of the outer casing 1 in the encapsulation groove 2, and thermal grease 11 is applied to the outer wall of the bottom of the heat-conducting plate 12. A semiconductor cooling chip 10 is provided on the outer wall of the bottom of the heat-conducting plate 12 and the thermal grease 11. When the semiconductor cooling chip 10 is activated, it works with the heat-conducting plate 12, the heat sink 13 and the thermal grease 11 to improve the heat dissipation efficiency of the driver chip 8, actively cool down and improve efficiency.

[0029] The bottom outer wall of the semiconductor cooling chip 10 is attached to the top outer wall of the driver chip 8, and the top outer wall of the heat-conducting plate 12 is welded with heat sinks 13 distributed at equal intervals. The top outer wall of the heat sinks 13 is provided with ventilation holes 14 distributed at equal intervals.

[0030] Fans 19 are installed in each bracket 18, and fixing holes are opened at both ends of the outer wall of the mounting plate 16. The mounting plate 16 is installed on the outer wall of the outer shell 1. After the fan 19 on the mounting plate 16 is started, it accelerates the airflow speed in the mounting plate 16. After the airflow passes through the ventilation holes 14 on the heat sink 13, the heat dissipation efficiency is improved.

[0031] The air inlet 17 and the ventilation hole 14 overlap each other, and the airflow direction of the fans 19 at both ends of the mounting plate 16 is the same. After the fans 19 are started, they drive the airflow to move in one direction. The airflow enters from the air inlet 17 and is discharged from the ventilation hole 14, which removes the heat from the heat sink 13, making it easy to dissipate heat and easy to use.

[0032] Working principle: During use, the entire unit is installed in the circuit through the mounting holes 4 on the outer casing 1. The driver chip 8 and other components are connected to the circuit through the connecting pins 7 on the circuit board 6. The driver chip 8 provides computing power to the drone's motors. The integrated temperature sensor 9 is located in the driver chip 8. When the temperature of the driver chip 8 reaches a certain level, the semiconductor cooling chip 10 is activated. The semiconductor cooling chip 10 absorbs and releases heat on one side, reducing the temperature of the driver chip 8. The heat conduction plate 13 and the heat sink 13 work together to transfer heat to the ventilation holes 14 for easy heat dissipation, ensuring the efficiency of the driver chip 8 and preventing high temperature from affecting the driver chip 8. The fan 19 on the bracket on the mounting plate 16 is activated. After the fan 19 is activated, it drives the airflow to move in one direction. The airflow enters through the air inlet 17 and exits through the ventilation holes 14, carrying away the heat from the heat sink 13 for easy heat dissipation and convenient use.
