Fan

Abstract

A fan is used to be fixed on an enclosure to dissipate heat from the enclosure. The fan includes a body, a magnetic fixing element mounted on the body, a power connector connected to the body; and a universal serial bus (USB) connector connected to the power connector. The body is fixed on the enclosure under magnetic force of the fixing element. The power connector and the USB connector are selectively connected to a motherboard to receive a voltage to power the body of the fan, to dissipate heat from the enclosure after the motherboard is powered on.

1 . A fan to be fixed to an enclosure to dissipate heat from the enclosure, the fan comprising:
 a body;   a magnetic fixing element mounted to the body;   a power connector connected to the body; and   a universal serial bus (USB) connector connected to the power connector;   wherein the body is fixed to the enclosure under magnetic force of the fixing element, the power connector and the USB connector are selectively connected to a motherboard in the enclosure to receive a voltage to power the body of the fan.   
     
     
         2 . The fan of  claim 1 , wherein the fixing element comprises a first magnetic fixing element and a second magnetic fixing element, at least one through hole is defined in the body, the first and second fixing elements are fixed to the body and at opposite ends of the at least one through hole under the magnetic force between the first and second fixing elements. 
     
     
         3 . The fan of  claim 2 , wherein the at least one through hole comprises three through holes, the first fixing element comprises a first sheet and two first pins extending up from the first sheet, the second fixing element comprises a second sheet and a second pin extending up from the second sheet, the first pins and the second pin respectively extend through the through holes to attract the second sheet and the first sheet together. 
     
     
         4 . The fan of  claim 3 , wherein the first and second sheets are both substantially L-shaped, the first pins extend from two ends of the first sheet, the second pin extends from a center of the second sheet. 
     
     
         5 . The fan of  claim 4 , wherein the body comprises a front wall and a back wall, the through holes are defined in a corner of one of the front wall and the back wall.
