A fan holder for mounting a fan, includes two opposite sidewalls defining a receiving area therebetween, each of the sidewalls defining a through hole therein; two or more polygonal auxiliary members arranged in the through hole of each of the sidewalls and located about an axis; and wherein the polygonal auxiliary members are rotationally offset from each other.
1. A fan holder for mounting a fan, comprising:
two opposite sidewalls defining a receiving area therebetween, each of the sidewalls defining a through hole therein;
three or more polygonal auxiliary members arranged in the through hole of each of the sidewalls and located about an axis;
and wherein the polygonal auxiliary members are rotationally offset from each other.
2. The fan holder as described in claim 1 , wherein the auxiliary members are triangular and the corners are connected to a circumference of the corresponding through hole.
3. The fan holder as described in claim 1 , wherein the auxiliary members are pentagonal and the five corners of the auxiliary member are connected to a circumference of the corresponding through hole.
4. The fan holder as described in claim 1 , wherein the through holes are circular and are centered about the axis.
5. The fan holder as described in claim 1 , wherein the polygonal auxiliary members comprise of flanges that are not parallel to any flanges of other auxiliary members.
6. The fan holder as described in claim 1 , further comprising two hollow sections that define an inner space; an opening located on the bottom of each of the hollow sections; the openings provide communication between the inner spare of the hollow section and the receiving area.
7. The fan holder as described in claim 6 , further comprising a through hole defined on an external surface of the hollow sections; wherein the through hole extends from the external surface to the inner space.
8. The fan holder as described in claim 7 , wherein the hollow sections are not fully enclosed.
