Description

Technical Field

[0002] As an important component of electronic equipment heat dissipation, cooling fans have a wide range of applications, including but not limited to computers, communication equipment, industrial control equipment, automotive electronics and other fields. With the rapid development of electronic technology, the integration of electronic equipment is getting higher and higher, and the power density is also increasing, making heat dissipation one of the key factors affecting the performance and stability of electronic equipment. Therefore, efficient and reliable cooling fans play a vital role in ensuring the normal operation of electronic equipment.

[0003] At present, the cooling fans on the market are mainly divided into two categories: DC brushless fans and AC fans. DC brushless fans use the Hall element on the circuit board to sense the magnetic field of the magnetic rubber magnet on the fan rotor, control the on and off of the winding coil on the silicon steel sheet, and generate attraction and repulsion to drive the fan to rotate. AC fans generate attraction and repulsion by switching the direction of coil power supply to drive the fan to operate. Existing cooling fans usually include a drive motor, fan blades, a casing and other parts. The drive motor drives the fan blades to rotate to generate airflow, thereby achieving the purpose of heat dissipation.

[0004] However, although the existing cooling fans have achieved certain results in cooling effect, in actual applications, the existing cooling fans still have some defects. The existing AC cooling fans are usually provided with a voltage-stabilized power supply for electrically connecting to the drive motor, so as to provide a stable voltage for the cooling fan. However, the existing voltage-stabilized power supply is generally directly placed outside the cooling fan, and there is a lack of connection structure between the voltage-stabilized power supply and the outer frame of the cooling fan.
