Computer power supply apparatus having fan control circuit for cooling standby power supply unit when computer is turned off and control method thereof

摘要

The present invention relates to a computer power supply device having a fan control circuit that cools a standby power supply unit in a state in which the computer is turned off, and generates a main power supply and a standby power supply. It consists of a power supply unit that supplies power to components, a cooling control circuit, and a sensor. The present invention is included in the computer main body by driving the fan with the standby power source of the power supply unit if the temperature or current of the components included in the computer main body rises above a certain value when the computer is stopped. By reducing the temperature or current of a component to a certain value or less, there is an advantage that a decrease in the durability of the component due to heat generation of the component can be reduced, and a shortening of the durable life of the component can be prevented.
