A fan module comprises a fan and a positioning frame cooperated with the fan. The fan comprising a fixing frame and a main body received in the fixing frame. The fixing frame forms a plurality of fixing columns, the positioning frame forms a plurality of fixing holes correspondingly to the fixing columns. The fixing columns are through the correspondingly fixing holes to fix the fan in the positioning frame.
1. A fan module comprising:
a fan and two positioning frame cooperating with the fan;
the fan comprising a fixing frame and a main body received in the fixing frame;
the fixing frame forming a plurality of fixing columns, the positioning frames defining a plurality of fixing holes correspondingly to the fixing columns;
the fixing columns penetrating through the correspondingly fixing holes to fix the fan on the positioning frames;
wherein the fixing frame comprises a top surface, two sidewalls extending from two ends of the too surface and a retaining wall extending from the too surface and connecting the sidewalls, and the top surface, the two sidewalls and the retaining wall collectively defining a cavity;
wherein the fixing frame further comprises a plurality of tabs extending perpendicularly therefrom, and the fixing columns extending from a side of the tabs.
2. The fan module of claim 1 , the further comprising a buckle, wherein one end of the buckle connects to one of the sidewalls, and another end of the buckle forms an extending portion for fixing the main body in the cavity.
3. The fan module of claim 2 , wherein two sides of the buckle are spaced from the sidewall of the fixing frame to define a gap.
4. The fan module of claim 1 , wherein a center of the top surface forms a sheet, an end of the sheet connects the top surface and another end is a free end beyond the top surface.
5. The fan module of claim 1 , wherein the main body comprises a frame, the frame has a front surface and a rear surface opposite to the front surface, the frame define another cavity, the another cavity extends through the front surface and the rear surface.
6. The fan module of claim 2 , wherein the retaining wall is located on a side of the cavity, and a positioning column is formed on the retaining wall and extends toward the cavity, wherein a through hole is configured on a corner position of the main body, and the positioning column is inserted into the through hole.
7. The fan module of claim 6 , wherein the position column passes through the through hole to receive the main body in the cavity, and the extending portion of the buckle attaches to a front surface of the frame.
8. The fan module of claim 1 , wherein the two positioning frames each has a plate shape and are arranged parallel to each other, and each of the positioning frames comprises an edgefold extending in a direction that is away from the other positioning frame, wherein the fixing holes are located on the edgefolds.
9. The fan module of claim 8 , wherein each edgefold comprises a first extending portion perpendicularly to the positioning frame and a second extending portion perpendicularly to the first extending portion, the second extending portion is parallel to and spaced from the positioning frame.
10. The fan module of claim 9 , wherein the first extending portion, the second extending portion and the positioning frame collectively define a U-shaped groove.
