## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a computer and a fixing bracket of the computer for fixing a fan.
2. Description of Related Art
In a computer system, peripheral component interconnect (PCI) cards, such as video cards, will generate a large of heat during operation, which may affect the operational stabilization of the computer system. Although fans or other heat dissipating components are utilized to dissipate heat for the PCI cards, it is difficult to meet heat dissipating requirements because the fans or the heating dissipating components are often too small to efficiently dissipate heat.

The fixing element 22 includes a cover plate 222 and a tab 224 perpendicularly extending from a top of the cover plate 222. An incision 2242 is defined in the tab 224. The base board 24 defines a rectangular opening 241 in a center, two parallel long first slots 243 at top and bottom sides of the opening 241, and a second slot 244 perpendicular to the first slots 243 and at an end of the opening 241. A flange 25 perpendicularly extends from an end of the base board 24, adjacent to the second slot 244. The connection plate 26 is perpendicularly connected between a side of the cover plate 222 of the fixing element 22 and the flange 25 of the base board 24.
Referring to FIGS. 3 to 4, in assembling the fan 10 with the fixing bracket 20, if a distance between two adjacent screw holes 12 of the fan 10 is equal to a distance between the two first slots 243 of the base board 24, four screws 2432 are respectively extended through the first slots 243 and engaged in the screw holes 12 (see FIG. 6), or two screws 2432 are respectively extended through the first slots 243, and another two screws 2432 are extended through the second slot 244, and then engaged in the screw holes 12 of the fan 10 (see FIG. 5). If the distance between two adjacent screw holes 12 of the fan 10 is less than the distance between the two first slots 243 of the base board 24, only three screws 2432 are needed to mount the fan 10 to the fixing bracket 20, one of which is extended through one of the first slots 243 and the other two are extended through the second slot 244, and then are engaged in the screw holes 12 of the fan 10. A first side of the fan 10 faces the opening 241 of the fixing bracket 20.
Referring to FIGS. 6 and 7, in assembling the combined assembly of the fixing bracket 20 and the fan 10 to the chassis 30, the assembly is supported on the motherboard 40 and faces the PCI card 50 with a second side of the fan 10 opposite to the first side, a screw 2244 is extended through the incision 2244 of the fixing element 22 and engaged in one of the plurality of fixing holes 322 of the chassis 30. Therefore, the fixing bracket 20 is mounted to the fixing portion 32 of the chassis 30, with the cover plate 222 of the fixing element 22 covering a corresponding slot 33 of the rear wall 31 of the chassis 30, and the fan 10 is just above some idle PCI sockets 42 and facing the PCI card 50 which is inserted in one of the plurality of sockets 42 nearby the fixing bracket 20. If all the screws 2432 are in the first slots 243, the position of the fan 10 on the base board 24 is able to be regulated along the first slots 243, according to location of the PCI card 50, to improve cooling efficiency for the PCI card 50.
In other embodiments, two holding elements may be movably mounted to the first slots 243. A hole may be defined in each holding element to fix the fan 10. It is able to adjust a distance between the two holding elements according to the distance of two adjacent screw holes 12 of the fan 10.
