Description
Technical Field
The invention particularly relates to a delay control system of a cooling fan.
Background
Due to the advancement of technology and the advancement of integrated circuit and various electronic device manufacturing processes, the operation and processing speed per unit time is increased, and the amount of heat generated is increased. In order to meet the requirement of the integrated Circuit (CPU) and the internal devices (such as optical disk drive and magnetic disk drive) driven by the CPU, the power supply must provide higher power output, and even more, the processing speed of each device of the computer is increased, and the generated heat is relatively increased, so that more fans must be installed to dissipate heat (according to the power source of the fan is still the power supply), so that the power supply must maintain the high power output mode to work in order to provide the power demand of the load, and the heat generated by the electronic components (such as rectifier, transformer, etc.) for step-down rectification is greatly increased, when the computer is running, the rectifiers, transformers, etc. of the electronic components and power supply can be blown by the preset fans to achieve the heat dissipation effect, however, when the computer is turned off by the user, the fan is stopped by stopping power supply and stopping wind power blowing, because the general working temperature of the integrated circuit, the electronic components, the rectifier, the transformer and the like is quite high, when the fan is stopped suddenly, the residual heat is accumulated gradually because of not being blown by wind power, the temperature of the fan rises suddenly and exceeds the normal working temperature for a long time, so-called temperature return phenomenon is generated, and the integrated circuit or the electronic components are damaged or the service life of the system is influenced in the period.
