Description

Fan module

Technical Field

The embodiments of the utility model relate to a fan module, and more particularly to a fan module with a strong structural strength.

Background Art

In recent years, laptops have become thinner and lighter, and the design space inside the laptop as a whole has been compressed, making pressure-resistant design more difficult. The fan module in the laptop has also been required to have enhanced pressure resistance. In conventional technology, the fan module generally includes a first metal plate, a second metal plate, and a plastic frame. The plastic frame is combined with the first metal plate by coating injection, and the second metal plate is combined with the plastic frame by snap-fitting. However, due to limitations such as size and processing conditions, reinforcing ribs cannot be set on the outside of the second metal plate of the conventional fan module. Therefore, when the fan module is subjected to external stress impact, the external stress cannot be smoothly transmitted to the outside of the fan module (for example, to the casing of the laptop), causing material damage to easily occur at the second metal plate.
