Technical Field

[0001] This utility model belongs to the field of cooling fan technology, and in particular relates to a cooling fan that can replace LED strips. Background Technology

[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 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 existing technology, various light strips are added to the fan to increase the diversity of cooling fans. However, the existing technology of mounting light strips on fans has the technical problem of fixing the connection between the light strip and the fan, which is irreplaceable. Utility Model Content

The LED strip device 30 has a positioning protrusion 31 on its side that engages with the limiting groove 111, and the positioning protrusion 31 can be completely accommodated in the limiting groove 111. The fan blade 20 is fixedly mounted on the drive end of the main mounting frame 10.

[0031] The replaceable LED strip cooling fan of this utility model is assembled from a main mounting frame 10, fan blades 20, and an LED strip device 30. At least one limiting groove 111 is provided on the side of the main mounting frame 10, and the inner sidewalls of the limiting groove 111 at both ends are arc-shaped. Two arc-shaped surfaces extend from the inner bottom of the limiting groove 111 towards both ends.

The two sides of the positioning protrusion 31 are also arc-shaped. Furthermore, the arc-shaped surface on the positioning protrusion 31 is adapted to the arc-shaped surface in the limiting groove 111. The fan blade 20 is fixedly installed on the drive end of the main mounting bracket 10. During assembly, the guiding effect between the arc-shaped surface on the limiting groove 111 and the arc-shaped surface on the positioning protrusion 31 is utilized to ensure that the positioning protrusion 31 can smoothly engage with the limiting groove 111 when the light strip device 30 is assembled. The light strip device 30 can be disassembled and replaced by the user according to their needs.
