this article relates to the technical field of computer chassis, in particular to a computer chassis side panel with an automatic cooling fan door.

with the development of chip technology, its running speed and frequency are getting higher and higher, and its processing capacity is getting larger and larger.the following problem is that its calorific value is also getting higher and higher.the current computer chassis are basically closed and its internal space is small, which is not conducive to the internal heat is discharged out of the chassis, which makes it difficult for computer accessories installed in the computer chassis to dissipate heat, especially CPU and video card, which generate the greatest heat.although the chassis has air exhaust holes, the design of the air exhaust holes should consider dust prevention, so the air exhaust holes should not be too large, so when the heating value of each computer accessory is large, the exhaust hole cannot discharge the heat in the chassis in time.if the heat cannot be discharged in time, each computer accessory in the chassis works at higher temperature, and its performance the more unstable the energy will be, the more it will affect the normal work and the longer its service life will be seriously shortened. Some chassis are equipped with heat dissipation fans on the front panel or the rear panel.the technical scheme is to install the heat dissipation fans at the positions with air exhaust holes on the rear panel of the chassis, and the wind direction is from the main board-side blowing to the other side, the heat dissipation effect is not ideal; If it is installed on the front panel of the chassis, the heat dissipation fan is separated from the outside by two layers of chassis iron plate and external panel, so that the air supply volume of the heat dissipation fan is small, and the heat dissipation fan is far away from computer accessories with large heat generation in the chassis

far away, its heat dissipation effect is not ideal.

the purpose of this paper is to provide a computer chassis side panel with an automatic heat dissipation fan door, which is equipped with a heat dissipation fan and can automatically open and close the automatic heat dissipation fan door, aiming at the defects of the prior Art..

in order to achieve the above objectives, this article is realized through the following technical scheme:it includes a chassis side plate, a heat dissipation fan and a heat dissipation fan base, wherein the heat dissipation fan is fixed on the heat dissipation fan base, the heat dissipation fan base is installed on the chassis side plate, and the heat dissipation fan base is also installed with automatic cooling fan door capable of opening and closing automatically.

the automatic heat dissipation fan door is divided into four independent fan blades, each fan blade is respectively fixed on its corresponding transmission rack, which is matched with the transmission gear in the gear box, and the intermediate gear is respectively connected with the transmission gear and the motor.

the radiator fan base is equipped with a ventilation iron net, which is located between the automatic radiator fan door and the radiator fan base.

the heat dissipation fan base is equipped with a travel switch, a status indicator and a manual switch.

in this paper, a cooling fan is installed on the side plate of the chassis, and an automatic cooling fan door is installed on the cooling fan.the automatic cooling fan door is fixed on a transmission rack, the transmission rack is driven by a motor through a gear, and the motor is controlled by a control circuit.when the computer is started and shut down, through the stroke switch and control circuit to control the rotation of the electricity and cooling fan power on and off, so as to realize the automatic cooling fan door automatically open and close and the cooling fan work when the computer is turned on and off. The structure of this article is simple, the airflow blown out by the heat dissipation fan is blowing towards the main board in a positive direction, so that the heat dissipation effect is good, and the automatic heat dissipation fan door is automatically closed when being shut down; a ventilation iron net is installed on the base of the heat dissipation fan, so that dust is more effectively prevented from adhering to the heat dissipation fan and entering the inside of the chassis.
