[0002] Cooling fans play a vital role in laptops because they help keep the hardware running at a suitable temperature, thereby ensuring device performance and extending service life. As the performance of laptop hardware continues to improve, the cooling system faces increasing challenges. In order to improve the cooling efficiency, the technology of cooling fans is also constantly improving, including fan design, material manufacturing process and other aspects. However, cooling fans are prone to shaking when rotating at high speeds, which is a technical problem. Fan shaking may cause the fixing stability between it and the cooling fins to decrease, increasing friction and wear between the two. This wear not only affects the cooling efficiency, but may also shorten the life of the fan and cooling fins, and even cause noise and dust problems. Utility Model Content

[0008] Preferably, a first clamping side panel is provided at both the front and rear ends of the protective bracket, and the first clamping side panel and the protective bracket are integrally formed, and the protective bracket is fixedly connected to the fan bracket and the cooling fan by clamping them on the thermal fins through the first clamping side panel and the second clamping side panel.

[0009] Preferably, the first clamping side plate clamps the outer shell of the heat conducting fin and is fixed thereto.
