Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and in particular relates to a heat dissipation fan which is easy to clean. Background Art

[0002] Cooling fans are an important cooling component for electronic equipment. Their main function is to dissipate heat by forcing air to prevent electronic components from overheating. Cooling fans are widely used in computers, medical equipment, heaters, refrigeration equipment and other fields. There are two basic types of cooling fans: axial fans and centrifugal fans. The blades of axial fans push the air in the same direction as the axis, while centrifugal fans push the air in a direction perpendicular to the axis.

[0003] During the use of the cooling fan, a large amount of dust is easily absorbed inside. The dust is easy to block the inside of the cooling fan, reducing the rotation speed of the fan blades inside the cooling fan, thereby reducing the air flow speed inside the cooling fan, so the cooling fan needs to be cleaned regularly.

[0004] In the prior art, when cleaning the interior of the cooling fan, the fan blades inside the cooling fan need to be removed to facilitate comprehensive cleaning of the cooling fan. However, the fan blades on the cooling fan are usually fixed to the output shaft of the cooling fan with bolts. When cleaning the cooling fan, the mounting bolts need to be removed multiple times, which is inconvenient for cleaning the cooling fan and increases the time required for cleaning the cooling fan.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
