Description

Computer case and fan fixing bracket thereon

The invention relates to a computer case and a fan fixing bracket thereover.

Heat dissipation is an important factor affecting the efficient operation of computer systems. PCI cards in conventional computer systems are a major heating component, such as a graphics card. Generally, a PCI graphics card may have a fan or other heat dissipating component. Since the heat dissipating components are limited by their own space, they cannot be made very large. Therefore, when the PCI graphics card runs efficiently, the heat dissipating components on the PCI graphics card are often not satisfied. The heat dissipation requirement, at this time, additional heat dissipation components are required to ensure the normal operation of the PCI card.

In practical applications, at least one PCI slot is generally idle in the computer system. If the space above the idle PCI slots can be used to set a fan to dissipate the PCI card, the heat dissipation problem of the PCI card will be obtained. solve.

In view of the above, it is necessary to provide a computer case that can be used to set a fan by utilizing the space above the unused PCI slot.

It is also necessary to provide a fan mounting bracket that places the fan over an unused PCI slot.

Referring to FIG. 1 , FIG. 2 , FIG. 6 and FIG. 7 , a preferred embodiment of the computer case of the present invention comprises a computer motherboard 4 , a PCI (Peripheral Component Interconnect) card 5 , a chassis shell 3 and a fan. Fix the bracket 2. The fan fixing bracket 2 can set a fan 1 on the idle PCI slot 42 of the computer motherboard 4.

A plurality of screw holes 12 are provided around the fan 1.

The fan fixing bracket 2 includes a fixing bracket 22, a bottom plate 24, a fixing plate 25 extending perpendicularly from one side of the bottom plate 24, and a fixing piece 26. The fixed baffle 22 has the same shape as a PCI baffle, and includes a substrate 222 and a flap 224 extending perpendicularly from one end of the substrate 222. The side edge of the flap 224 is provided with an opening 2242. A rectangular opening 241 is defined in the middle of the bottom plate 24, and two parallel first slots 243 are defined in the two opposite sides 242 of the opening 241, and a first side perpendicular to the two sides is disposed adjacent to the fixing plate 25. The second slot 244 of the slot 243. The fixing piece 26 extends perpendicularly from a central portion of the fixing plate 25 and is fixedly coupled to the substrate 222 of the fixing piece 22.

The chassis housing 3 includes a fixing member 32 for fixing a PCI card, and the fixing member 32 is provided with a plurality of screw holes 322.

Referring to FIG. 3 and FIG. 4 together, when the fan 1 is assembled to the fan fixing bracket 2, the first and second slots 243 and 244 are inserted through the screws 2432 and locked into the screw holes 12 of the fan 1. The fan 1 is fixed to the fan fixing bracket 2. When the fan 1 is adjacent The distance between the two screw holes 12 is smaller than the distance between the two first slots 243, and the fan 1 can be fixed to the fan fixing bracket 2 through three screws 2432, wherein the two screws 2432 pass through the second The slot 244 is opened, and another screw 2432 passes through the two first slots 243.

Referring to FIG. 5, when the distance between two adjacent screw holes 12 of the fan 1 is equal to the distance between the two first slots 243, the through screws 2432 can pass through the two first slots 243 and lock.
