Patent ID: 8804338

Claim:
Electronic equipment comprising: a portable terminal comprises: an exothermic body; a first heat conducting path for conducting exothermic heat from the exothermic body; and a first heat discharging means for discharging the exothermic heat conducted through the first heat conducting path, wherein a function and performance of the portable terminal is restricted at a prescribed first temperature or above, and the function and performance of the portable terminal is not restricted below the prescribed first temperature; an external device couplable to the portable terminal, the external device comprises: a second heat conducting path to be thermally connected to the first heat conducting path; and a second heat discharging means for discharging the exothermic heat conducted through the second heat conducting path, a control means for controlling the heat discharging path of the exothermic body, wherein when the portable terminal is coupled to the external device, the control means maintains a thermal connection between the first heat conducting path and the first heat discharging means under a first condition, the first condition is when the portable terminal is below a prescribed second temperature and shuts down or reduces the thermal connection between the first heat conducting path and the first heat discharging means under a second condition, the second condition when the portable terminal is equal to or greater than the second temperature, the second temperature being equal to or less than the first temperature.
