Description

Technical Field

[0002] With the rapid development of electronic technology, the operating speed of heat-generating electronic components such as central processing units is getting faster and faster, and the heat generated during their operation is also increasing accordingly. In order to dissipate this heat and ensure the normal operation of electronic components, the industry uses fans to cool electronic components. Traditional fans generally include a stator, a rotor, and a fan frame that houses the stator and rotor. The rotor usually includes a hub and several fan blades that are evenly arranged around the hub and radiate outward. In the prior art, two cooling fans are fixedly connected by connectors or screws. When a fan malfunctions or is damaged, the relevant components are disassembled for repair or replacement to restore the fan to normal function. For example, the fan and fan assembly disclosed in CN101307769A includes: an impeller and a motor, the motor driving the impeller to rotate; a circuit board electrically connected to the motor; a fan frame housing the impeller and the motor; and a connector disposed on one side of the fan frame. The circuit board is located between the connector and the fan frame. Since the circuit board is disposed outside the fan frame, the circuit board area can be increased, and the number or size requirements of the electronic components disposed on the circuit board are less restricted, resulting in greater flexibility in structural design.
