Accordingly, when the temperature of the semiconductor device 172 rises above the predetermined temperature, the control unit of the mobile terminal 100 transmits a signal regarding the operation of the fan 230 to the control unit 201 of the cradle 200.

Then, the control unit 201 of the cradle 200 operates the fan 230 to further enhance the heat radiation performance.

Conversely, when the temperature of the semiconductor element 172 drops below the set temperature while the fan 230 is operating, the control unit 170 of the mobile terminal 100 controls the control unit 201 of the cradle 200, To signal the shutdown of the fan (230).

Then, the control unit 201 of the cradle 200 stops the operation of the fan 230.

On the other hand, although not shown, a graphite sheet may be attached to the front surface of the battery cover 50. In this case, since the heat generated in the control board 170 is dissipated through the third conductor 183 and spreads widely through the graphite sheet, the heat radiation performance can be further improved.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.

The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
