this article is about a computer cooling fan fixing frame, in particular to a computer cooling fan fixing frame which can fix the cooling fan at a specific angle to make the whole computer system have good ventilation and cooling effects.

in existing personal computers, the main heat source is the central processing unit on the motherboard.it is usually installed in the computer casing slightly close to the side of the power supply, and the heat generated by the central processing unit in the computer casing is discharged through the heat dissipation fan of the power supply 。 For some central processing units with better performance and faster speed, in order to achieve better heat dissipation effect, an independently operated heat dissipation fan is usually additionally arranged on the front panel of the computer casing to suck in cooling air outside the computer casing and cooperate with the the fan generates convection in the computer casing. However, most of these independently operated fans are installed at the lower or one-side of the front plate.the fans only suck cooling air and cannot blow the cooling air effectively and directly to the location where the CPU is located.the system the heat generated by the internal CPU must still be exhausted from the outside of the computer case through passive convection of the internal air. Therefore, compared with the computer system architecture without the heat dissipation fan, the computer system architecture with the heat dissipation fan does have limited effect.

  For example, in Taiwan patent applications nos.8121798 and 82209882, a fan is additionally installed on the front panel of the computer case and is matched with the fan of the power supply to dissipate heat, i.e.the fan of the front panel blows air, and the fan of the power supply blows air to increase the cooling effect inside the computer casing, but the fan of the front board is perpendicular to the front board to supply air to the motherboard, and it does not supply air to the CPU, the main heat source on the motherboard, so that the fan of the front board, the CPU and the power supply fan cannot be a good heat exchange channel is formed, resulting in a large amount of heat generated by the central processing unit still remaining inside the computer casing.

in view of this phenomenon, the prior art additionally provides a heat dissipation method inside the computer mainframe.for example, Taiwan patent application No.84214048 discloses an air exhaust device, which combines a fixing seat which can cover the side surface of the fan blade of the exhaust fan on the side surface of the exhaust fan, air it is sucked by fan blades through an air suction port on the fixed seat and then discharged from an air exhaust surface of the exhaust fan, and the CPU.a cover is installed above the CPU.one end of a duct is sleeved with the air suction port of the fixed seat and the other end is sleeved with the connection interface of the cover, so that the CPU the heat generated by the heater is completely discharged out of the host through the duct exhaust fan. However, this kind of structure is complicated and not suitable for smaller computer cases.

one of the purposes of this paper is to provide a computer cooling fan holder with good air guiding effect. The purpose of this paper is realized through the following scheme:the computer cooling fan fixing frame is installed in the computer casing provided with the central processing unit, and is used for fixing the cooling fan to the front plate of the computer casing , which comprises a first wall surface, a second wall surface, a third wall surface, a fourth wall surface and a fifth wall surface, wherein the second wall surface is parallel to the first wall surface, the third wall surface is orthogonal to the first wall surface and the second wall surface, and the fourth wall surface is connected with the first wall surface and the second wall surface and is opposite to the first the three walls are inclined at an angle, and the fifth wall, the first wall, the second wall, the third wall and the fourth wall form a space for installing the fan, and the fifth wall _ is provided with an opening for exposing the fan, and a plurality of fixed heat dissipation the elastic hook of the fan, the fifth wall surface forms a certain included angle with the front plate of the computer case, which can make the fan device form an angle with the front plate behind the computer fan fixing frame and supply air to the CPU on the mainboard.

through the above technical scheme, this paper can make the cooling fan device fixed on the front panel of the computer case behind the computer fan fixing frame and blowing air to the CPU, thus improving the cooling effect inside the computer system.
