Abstract:
A centrifugal fan comprises a casing and a fan impeller. The casing comprises a first cover, a second cover, a side wall structure and a isolating structure. The side wall structure is connected between the first cover and the second cover to form an accommodating space. The side wall structure includes a first air inlet and an air outlet. The isolating structure is disposed between the first cover and the second cover to distinguish the accommodating space into a first subspace and a second subspace. The isolating structure includes a through hole. As a result, airflow is guided from a side to the first air inlet easily. Then, the air inlet volume and air outlet volume of the centrifugal fan are improved.

Claim (Index 4):
The centrifugal fan according to  claim 3 , wherein the guiding channel includes a first guiding side wall and a second guiding side wall, an end of the first guiding side wall and an end of the second guiding side wall are adjacent to two sides of the first air inlet, respectively, the end of the first guiding side wall and the end of the second guiding side wall are extended towards a direction away from the fan impeller.
