Fan support structure and metal plate for fabricating the same

Abstract

A fan support structure is integrally formed by bending a metal plate. The fan support structure includes a first plate area and a second plate area extended from a first edge of the first plate area and perpendicular to the first plate area. At least one through hole is disposed at the first plate area. The first edge of the first plate area and a second edge of the first plate area opposite to the first edge of the first plate are extended to form at least one slot structure. Directions in which the first edge and the second edge of the first plate extend and are formed are opposite to a direction in which the second plate area extends and is formed. Openings of the slot structure are opposite to each other. The slot structure is used to hold a filter screen.
