Abstract
The fan of the invention includes a frame and a vibration absorber. The frame has a fixing recess at a corner thereof. The vibration absorber has an elastic body fastened in the fixing recess and a pin with a circular trough. A portion of the elastic body protrudes from the frame. The pin is fixed at the portion of the elastic body for fastening the frame on a panel.
Description
- 1. Technical Field
- The invention relates to fans, particularly to fans for heat dissipation.
- 2. Related Art
- Heat dissipation devices are very important to modern electronic apparatuses. Usually, a fan is applied in a heat dissipation device to take heat away or make air flow. However, a fan vibrates when operating. The vibration of a fan will generate noise and make the screws which fasten the fan loosen.
- A conventional solution against vibration is to use a rubber washer between a fan and a mount panel. But the rubber washer is not very easy when assembling because the rubber washer must be aligned with a screw.
- Another conventional solution is shown in
FIG. 1 , in which arubber pin 30 and arubber washer 40 are used. Therubber pin 30 is formed with two expandedcones 34 to divide into threesections bottom 341 of thecone 34 forms a supporting surface to support two opposite sides of afan 60 by inserting thepin 30 into ahole 601 of thefan 60. Therubber washer 40 is located between thefan 60 and amount panel 50. Thus therubber pin 30 andrubber washer 40 can absorb the vibration of thefan 60. - However, in the above structure, the rubber pin is too thin to have enough strength. Thus the rubber pin tends to be broken when assembling.
- An object of the invention is to provide an anti-vibration fan, which has sufficiently structural strength and can be easily assembled or disassembled.
- To accomplish the above object, the fan of the invention includes a frame and a vibration absorber. The frame has a fixing recess at a corner thereof. The vibration absorber has an elastic body fastened in the fixing recess and a pin with a circular trough. A portion of the elastic body protrudes from the frame. The pin is fixed at the portion of the elastic body for fastening the frame on a panel.

FIGS. 2 and 3 . The invention includes afan 10 and four vibration absorbers 20. Thefan 10 is composed of aframe 11 and afan core 101. Four corners of theframe 11 are separately formed with fourfixing recesses 12. Each of thefixing recesses 12 is provided with twoprotrusion 121 at an opening thereof and twobars 122 on the inside thereof. In fact, onebar 122 is also available. - Each of the vibration absorbers 20 is composed of an
elastic body 25 made of plastic, rubber or silicone and twopins 21 which oppositely protrude from theelastic body 25. Each of thepins 21 is formed with acircular trough 22 which abuts against theelastic body 25. The surface of theelastic body 25 is formed with twoalcoves 23 corresponding to theprotrusions 121 and twoslots 24 corresponding to thebars 122. Theelastic body 25 is fastened in thefixing recess 12 by embedding theprotrusions 121 and thebars 122 into thealcoves 23 andslots 24, respectively. - Please refer to
FIG. 4 . Thefan 10 of the invention may be fixed on apanel 91 of an electronic device such acomputer 90. There areholes 92 in thepanel 91 for being penetrated by thepins 21. Thepanel 91 is nipped in thecircular trough 22 to fasten thefan 10 on thepanel 91. - Please refer to
FIGS. 5 and 6 . The ends of theelastic body 25 protrude from theframe 11. That is to say, the height of theelastic body 25, which is annotated as H1, is larger than the height of theframe 25, which is annotated as H2. The height difference will make a gap between thepanel 91 and theframe 25. In other words, theframe 25 is not in direct contact with thepanel 91. The vibration caused by thefan 10 will be absorbed by theelastic body 25 but not be transferred to thepanel 91. - The
frame 11 is provided with alamp 13, which may be an LED. Thelamp 13 may light up thefan core 101. -
FIG. 7 shows another type of thefan core 101. - Please refer to
FIGS. 8 , 9, 10 and 11, which show another embodiment of the invention. Theelastic body 25 is formed with aprotrudent seat 201. Thepin 21 is fixed on theprotrudent seat 201. The outer end of theprotrudent seat 201 protrudes from theframe 11 and thecircular trough 22 is located on thepin 21 and near theprotrudent seat 201. Thepanel 91 to be fastened by thefan 10 can be nipped in thecircular trough 22 and abut against theprotrudent trough 201.
