Description

Technical Field

[0001] This utility model relates to the technical field of server heat dissipation equipment, and in particular to a cooling fan. Background Technology

[0002] As server performance continues to improve, its heat generation also increases, making heat dissipation a more prominent issue. As an important component of the server cooling system, the performance of the fan directly affects the stable operation of the server.

[0003] Traditional server cooling fans typically focus solely on heat dissipation performance, neglecting dust prevention. Dust accumulation on fan blades and heat sinks reduces cooling efficiency and can even lead to fan malfunctions, affecting the normal operation of the server.

[0004] In existing technologies, dust filters are installed on cooling fans to reduce dust ingress to some extent. However, after prolonged use, dust often accumulates on the filters, and when the dust accumulates to a certain level, it affects the fan's airflow and consequently the server's cooling performance. Furthermore, cooling fans are often connected to the server with screws, making it inconvenient to remove them for cleaning. Utility Model Content
