Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically a novel cooling fan. Background Technology

[0002] CPUs, power supplies, and other components are typically housed inside a computer case. These components generate heat during operation. If this heat is not dissipated from the case in a timely manner, the internal temperature will rise, affecting the efficiency of the components and potentially causing them to burn out. Therefore, cooling fans are usually installed on the front panel, rear panel, top cover, and bottom panel of the computer case, with a reasonable airflow arrangement to expel heat from the case and maintain a relatively suitable internal temperature.

[0003] Existing cooling fans are basically composed of a fan frame and fan blades. The cooling fan installed in the case rotates at a certain speed to ensure that the heat inside the case is dissipated. Common fans, after being powered on, generate airflow by rotating the blades to reduce the temperature of the case. The operation of the fans is achieved by connecting data cables, allowing multiple fans to work at the same time. The way to control and connect the fans involves splicing multiple data cables, which makes it impossible to achieve a clean and aesthetically pleasing overall design. In addition, the noise of existing cooling fans affects their lifespan and user experience. Utility Model Content
