Computer heat dissipation fan capable of being automatically controlled

Back to list Release date: Mar 23, 2020

this paper relates to the technical field of computer peripheral equipment, in particular to an automatic computer cooling fan , which is controlled by the change of external temperature.

background:

computer chassis are generally equipped with CPU, hard disk, optical drive, recorder and other equipment, each equipment will emit a lot of heat when working, so that the internal temperature of the chassis is much higher than room temperature, affecting the work of the computer; In summer, too high room temperature will also affect the computer department equipment work. The existing chassis cooling fan can discharge the heat inside the computer in time, but it also has some disadvantages.for example, the cooling fan starts to work as soon as the computer is turned on, which increases the power consumption of the computer.at the same time, the cooling fan does not stop working, and also in the constant noise, users do not know whether the interior of the chassis needs to be cooled down.


content of utility model:

the purpose of this paper is to provide a computer cooling fan which can be automatically controlled in view of the shortcomings of the prior Art.when the outside temperature is greater than the set value, the cooling fan starts automatically and can display the temperature value.

in order to achieve the above purpose, this paper adopts the following technical scheme:it includes a heat dissipation fan, the heat dissipation fan is connected to a main control chip through a fan control circuit, the main control chip is connected to a program controller, the main control chip is also connected to a temperature probe and a plurality of key switches, and the temperature probe the head is placed inside the cabinet.through the adjustment of the program controller and the preset value, when the temperature of the temperature probe is equal to or greater than the set value, the main control chip controls the heat dissipation fan to start to realize automatic control.

the main control chip is connected with an LCD display screen, which is used to display temperature, fan, hard disk, time and other information.

the main control chip is connected with a buzzer.when the temperature is too high, the buzzer will give an alarm. The main control chip is connected with an LED indicating circuit, and when the temperature is too high, the LED indicating circuit gives an alarm.

the main control chip is connected with a hard disk indicating circuit.

in this paper, firstly, the program controller should be preset in value, and the temperature probe should be placed at the corresponding position in the chassis.when the temperature of the temperature probe exceeds the set value, the main control chip controls the heat dissipation fan to start and realize automatic control.temperature, fan, time, hard disc work information can be displayed on the LCD display screen, very intuitive. This article has the characteristics of simple operation and better use effect.
