The role of 220V Cooling Fan framework

One kind of "220V Cooling Fan" framework, the fan frame contains a hollow shell seat, and a seat disposed in the housing board. The seat shell comprises a ring wall, a wall of the ring surrounded by a defined receiving space and a plurality of projecting to the ring wall projecting ribs. The ring wall having a face into the wind, an outlet side, and a connection to the connection surfaces of the plane into the wind, and the wind surface between, "220V Cooling Fan" into the wind surface and the wind surface is to a direction away from each other extends obliquely, the projecting ribs protruding to the ring on the wall, so that the ring wall forming a stepped incline aspect, two adjacent projecting ribs are formed corresponding recess. Impact noise produced at the time by the ring wall of the recess formed by the protruding ribs, "dota2雷竞技下载 " can effectively reduce the air flow, but also can reduce the airflow spoiler phenomenon, thereby increasing the amount of wind.
