And merge with the air flow of the main intake passage 112, thereby increasing the amount of air entering. Please refer to Figure 2 for a schematic view of the first section along the A-A section. An auxiliary airflow Aa is introduced into the 5^542482 4 main intake passage 112 via the auxiliary intake passage ι3, and merges with one of the main airflows Am introduced through the main intake passage 112. However, when the auxiliary airflow Aa is introduced, since the position of the side screw hole 111 is lower than that of the auxiliary air inlet port 13, the auxiliary air flow Aa is first passed through the bolt 114 locked to the screw hole 1U, and then The auxiliary intake passage 113 is introduced into the main intake passage 112. Since the screw 114 is not a smooth curved surface, noise of wind cuts is generated. At the same time, the side auxiliary air flow Aa merges into the main air flow Am in a nearly vertical direction to form a turbulence or vortex, thereby reducing fan performance. Therefore, how to provide a fan and its fan frame can improve the performance of the fan and avoid the noise of the wind cutting sound is one of the important topics.
