Description

Fan with cooling device

Technical Field

The invention relates to a fan, in particular to a fan which is easy to arrange wires, does not expose LED wires and does not influence the light emitting and heat dissipating effects.

Background

In order to avoid the problem that the electronic device is not degraded in performance or even damaged due to the accumulation of waste heat, a heat dissipation fan is usually used to guide airflow for heat dissipation. In addition, the conventional heat dissipation fan not only has heat dissipation effect, but also is widely applied with Light Emitting Diodes (LEDs) and combined with the heat dissipation fan, so that the heat dissipation fan can generate colorful visual effect while operating, thereby improving the added value of the product and increasing the purchase desire of consumers.

The conventional fan including LED wires is to assemble the LED wires to the edge of the fan frame, and then the LED wires are routed to the PCB (printed circuit board) end along the ribs of the fan, and the redundant wires are squeezed back to the PCB or the inside of the fan base, so as to ensure that the wires on the ribs do not run out and interfere with the fan blades. However, this approach, in addition to being difficult to wire dress, also risks the wire that is squeezed back to the PCB breaking.

In addition, other methods are also available, in which the LED wires are LED out from the PCB, and are routed to the edge of the fan frame along the ribs of the fan, and then the LED wires are assembled on the edge of the fan frame, and the excess LED wires are irregularly twisted and flattened so as not to run out of the edge of the fan frame and interfere with the fan blades. However, it is difficult to standardize the wire arrangement operation of the LED wires, and the LED wires are obviously exposed to the rim of the fan frame.

Therefore, if a fan which is easy to arrange wires, does not expose LED wires and does not affect the light emitting and heat dissipating effects can be provided, a great breakthrough will be brought to the technology in this field.
