traditional computers mainly rely on the exhaust fan in the main power supply to dissipate heat.after the power supply is turned on, the exhaust fan starts to work.through the through holes provided in the main chassis, external air is sucked into the chassis, and then enters the main power supply through the mainboard, hard disk, CPU, CD-rom, etc.and is exhausted by fan is discharged out of the chassis, although it has a heat dissipation effect, dust mites in the air are easily sucked into the chassis and reside on various circuit boards.the accumulation over the years not only affects the heat dissipation of the circuit itself, but also easily causes leakage between circuit electrodes due to humidity in the air electricity, when running at high speed makes the computer crash easily. In particular, the faster the CPU is now running, the higher the degree of heat dissipation is required, and the original way of heat dissipation by the exhaust fan on the main power supply cannot meet the requirements.

this article introduces a computer cooling fan combination mechanism which can accelerate the heat dissipation in the chassis, and the secondary purpose is to filter and sterilize the passing air.

in order to achieve the above purpose, this computer cooling fan assembly mechanism is mainly composed of a computer fan and a photocatalyst net installed on the air inlet of the computer fan.

an air filter screen is arranged between the photocatalyst screen and the air inlet of the computer fan.

it also includes a fan rack for placing the computer heat dissipation fan, which is fixed on the computer main machine shell, and the computer fan can be conveniently placed in the fan rack.

text computer cooling fan is mainly composed of a box-shaped fan body, fan blades and fan blade fixing brackets; The fan blade fixing bracket is fixedly connected to the fan body, and the fan blades are movably arranged on the fan blade fixing bracket; The hollow cavity of the box-shaped fan body forms an air channel, and the a photocatalyst net is arranged on the air inlet.

any position of the air channel is provided with one or more ultraviolet light emitting diodes which can fully irradiate the photocatalyst net.

a convex column is arranged on the box-shaped fan body at the other end corresponding to the air inlet of the air channel, and the convex column forms the fan blade fixing bracket; The fan blade is in the shape of a worm wheel, the central hole of the fan blade is sleeved on the convex column and can rotate around the convex column, and the fan blade can rotate in the wind

this article can also install the conventional computer fan in a box-shaped fan body with air inlet and outlet, form an air channel between the conventional computer fan and the air inlet of the fan body, and set an air filter screen on the air inlet.

any position of the air channel is provided with one or more ultraviolet light emitting diodes which can fully irradiate the photocatalyst net.

a fixing frame for installing an ultraviolet light emitting diode is convexly arranged in the box-shaped fan body.

this computer fan can also be composed of a box cover, an air filter screen, a connecting frame, an ultraviolet light emitting diode, an arch bracket, a plurality of conventional computer fans and a shell. The air filter net and the photocatalyst net are sleeved in the box cover and then sleeved in the connecting frame together; Uv the led is installed on the bow-shaped bracket. The bow-shaped bracket is installed on a plurality of conventional computer fans; A plurality of conventional computer fans are sleeved in the shell; The connecting frame is fixedly connected to the shell through screws, so that an air filter screen arranged in the connecting frame and ultraviolet rays emit light the diodes are arranged opposite to each other and the ultraviolet light emitting diodes can fully irradiate the photocatalyst net.

the plurality of conventional computer fans are composed of three parallel conventional computer fans.

the computer cooling fan combination mechanism has the following advantages:

1) speed up the circulation of air in the chassis to accelerate heat dissipation;

2) the circulation direction of air in the chassis is changed, air is fed from the air inlet of the utility model and is discharged through the through hole on the chassis, dust mites in the air are filtered through the filter screen during the air feeding process, so that dust is difficult to deposit on the circuit board of the chassis;

3) harmful gases in the air:formaldehyde, toluene, methanol, etc.can be decomposed by irradiation with photocatalyst net and ultraviolet diode. Destroy the cell membrane of the bacteria and degrade the organic matter in the cells step by step, causing the bacterial cells to die; Coagulation of viral proteins to inactivate gas, improve the quality of life. Since the utility model can be detached and used alone in the environment such as cars or bedrooms, there is no need to purchase an additional air freshener, thus reducing the occupied area and beautifying the environment.
