An extension of the life of the device and a fan motor control system for saving energy (and saving the life time of an electric device)

摘要

The present invention relates to an electronic device having a semiconductor device and a method of controlling the temperature of the device by maintaining the internal temperature of the device at a reference temperature so that the lifetime of the device is extended and electric energy can be saved, (10) for detecting a temperature in an electronic device, and a control unit (10) for setting a reference temperature in the electronic device and setting a reference temperature for comparing the reference temperature (Ts) A temperature setting and temperature comparing section 20 and a fan motor driving section 30 for driving the fan motor 40 in response to signals from the reference temperature setting and temperature comparing section 20.
