Description

computer fan bracket

The utility model relates to a computer fan fixing frame, in particular to a computer fan fixing frame which can fix the fan at a specific angle so that the computer system as a whole has good ventilation and heat dissipation effects.

In existing personal computers, the main heat source is the central processing unit on the main board, which is usually installed on the side of the computer casing slightly close to the power supply, and the central processing unit in the computer casing is cooled by the fan of the power supply. The heat generated is dissipated. For some CPUs with better performance and faster speed, in order to achieve better heat dissipation, an independently operated fan is usually provided on the front panel of the computer case to cool the cooling air outside the computer case. Inhale, and cooperate with the fan of the power supply to generate convection in the computer case. However, most of these independently operated fans are installed on the bottom or one side of the front panel. The fan only sucks the cooling air, but cannot immediately blow the cooling air effectively and directly to the position where the central processing unit is located. The central processing unit in the system The heat generated must still be exhausted outside the computer case by passive convection of the internal air. Therefore, compared with the computer system architecture without additional fans, the improved efficiency of the computer system architecture with fans is indeed limited.

For example, Taiwan Patent Application No. 81217798 and No. 82209882, they all install a fan on the front panel of the computer housing and cooperate with the fan of the power supply to dissipate heat, that is, the fan on the front panel carries out air supply, and the power supply The fan draws air to improve the heat dissipation effect inside the computer case, but the fan on the front panel supplies air to the mainboard perpendicular to the front panel, but does not supply air directly to the CPU, the main heat source on the mainboard, so that the front panel A good heat exchange channel cannot be formed between the fan of the board, the central processing unit and the fan of the power supply, so that a large amount of heat generated by the central processing unit remains in the inside of the computer casing.

Aiming at this phenomenon, the prior art additionally provides a cooling method inside the mainframe computer. For example, Taiwan Patent Application No. 84214048 discloses an exhaust device, which is combined with a fan that can be covered and held on the exhaust fan on the side of the exhaust fan. The fixed seat on the side of the leaf, the air is inhaled by the fan blade through a suction port on the fixed seat, and then discharged from the exhaust fan, and a cover is installed above the central processing unit, and one end of a duct is connected to the air suction port of the fixed seat. The other end is socketed with the connection interface of the cover, so that the heat generated by the central processing unit can be completely exhausted from the outside of the host through the duct exhaust fan. But this structure is cumbersome and complicated, and it is not suitable for smaller computer casings.

For patents related to the prior art, please refer to Taiwan Patent Application Nos. 85206856 and 85111330, etc.

The other side of the front plate 12 relative to the magnetic frame 18 is provided with a plurality of ventilation holes 21 , and the outside of the ventilation holes 21 is provided with a plurality of fastening openings 23 . The motherboard 30 is installed on the side of the bottom plate 16 of the computer case 10 close to the air hole 21 . The power supply 40 is installed on the rear panel 14 of the computer housing 10, and the central processing unit 32 is arranged in the motherboard 30 and adjacent to the power supply 40, and a fan (not shown) is also arranged in the power supply 40. Moreover, a side of the rear panel 14 close to the power supply 40 is also provided with a plurality of ventilation holes 25 .

Please refer to FIG. 3 to FIG. 5 , the four corners of the fan 50 are respectively provided with through holes 52 . The computer fan holder 60 is surrounded by five walls, including the first wall 62, the second wall 64, the third wall 66, the fourth wall 68 and the fifth wall 72, wherein the first wall 62 and the second wall The walls 64 are parallel to each other, the third wall 66 is perpendicular to the first wall 62 and the second wall 64, the fourth wall 68 is inclined at a specific angle relative to the third wall 66 and forms a connection with the first wall 62 and the second wall 64, The first wall surface 62, the second wall surface 64, the third wall surface 66 and the fourth wall surface 68 then encircle a passage, because the third wall surface 66 and the fourth wall surface 68 are not parallel to each other, the fourth wall surface 68 of the passage is inclined. The fifth wall 72 is perpendicular to the fourth wall 68 and encloses the first wall 62 , the second wall 64 , the third wall 66 and the fourth wall 68 to form a space 74 for installing the fan 50 . A circular opening 76 is formed on the fifth wall 72 , and two symmetrical elastic hooks 78 extend from both sides of the opening 76 to the space 74 of the computer fan fixing frame 60 . The elastic hooks 78 are respectively connected to the third wall 66 and the fourth wall 68 by reinforcing ribs 81 , and the fifth wall 72 is provided with a plurality of fixing protrusions 83 corresponding to the through holes 52 of the fan 50 . Relative to the fifth wall 72, the first wall 62 is provided with an elastic hook portion 85, while the second wall 64 is provided with a fastening portion 86, and the third wall 66 forms a protruding fastening piece 87, and the first The other end edges of the wall 62 and the second wall 64 both extend outwards with wind guiding vanes 89 for guiding wind.

Please also refer to Fig. 6 and Fig. 7, the fan 50 is installed in the space 74 of the computer fan fixing frame 60, and is buckled on both side edges of the fan 50 through the elastic hooks 78 in the space 74, and the computer fan fixing frame 60 The protrusion 83 of the fan 50 is then snapped into the through hole 52 of the fan 50 so that the fan 50 is fixed on the computer fan fixing frame 60 . The computer fan fixing frame 60 can be hung into the fastening port 23 of the computer housing front plate 12 earlier through the fastening portion 86 and used as a rotating shaft, and then the computer fan fixing frame 60 can be rotated a little to make the fastening piece 87 also enter the corresponding The fastening port 23 is finally fastened to the corresponding fastening port 23 through the elastic hook portion 85 , so that the computer fan holder 60 with the fan 50 is fixed on the computer case 10 .
