Electronic equipment having integrated circuit device and temperature sensor

An electronic device comprising:

• a circuit board section for effecting a preset signal process including at least one integrated circuit device including a package, an integrated circuit chip disposed in said package, a PTC (Positive Temperature Coefficient) thermistor disposed between said package and said integrated circuit chip and outputting a temperature change signal in the form of a resistance change, an abnormal temperature detecting chip for outputting an abnormal temperature signal when an output of said PTC thermistor has exceeded a preset value, and an electrical deriving member disposed in said package and effecting signal transfer with respect to said integrated circuit chip, PTC thermistor and abnormal temperature detecting chip;
• temperature controlling means for controlling the temperature of said circuit board section;
• and
• determining means for determining at least one abnormal temperature state in said circuit board section and an abnormal temperature state of said integrated circuit device according to an output of said abnormal temperature detecting chip and controlling at least one of said temperature controlling means and said circuit board section;
• wherein said temperature controlling means includes a refrigerant cooling system including a refrigerant inlet duct, a refrigerant flowing path, and a forced exhaust fan mechanism controlled by said control means based on an output of said PTC thermistor, and an alarm Unit controlled by said control means based on an output of said thermistor;
• and
• said determining means includes storing means for storing at least one of schedule data indicating a signal processing schedule effected in said circuit board section and specification data indicating the software specification and hardware specification of said circuit board section, and means for identifying at least one abnormal temperature state in said circuit board section and an abnormal temperature state of said integrated circuit device based on an output of said PTC thermistor and at least one of the schedule data and specification data.
