a second heat transfer portion to transfer heat from the electric device to the sealing unit, the second heat transfer portion being formed on one surface within the sealing unit; and
a heat transfer preventing portion configured to reduce the amount of heat transferred from the frame to the display module, the heat transfer preventing portion being located on the second surface, the heat transfer preventing portion overlapping the first heat transfer portion.
2. The terminal of claim 1 , wherein the heat transfer preventing portion comprises an air gap to space the frame apart from the display module.
3. The terminal of claim 1 , wherein the heat transfer preventing portion comprises an insulator interposed between the frame and the display module.
4. The terminal of claim 1 , further comprising a battery located within the terminal body,
wherein the terminal body includes a rear case and a battery cover to cover the battery and the rear case, and
wherein the printed circuit board is disposed between the rear case and the frame.
5. The terminal of claim 4 , further comprising a protrusion formed on a predetermined region of an inner surface of the battery cover such that an air gap is formed between the rear case and the battery cover, the predetermined region overlapping the heat transfer portion.
6. The terminal of claim 4 , further comprising an insulator formed on a predetermined region of an inner surface of the battery cover so as to prevent heat from being transferred to an outer surface of the battery cover, the predetermined region overlapping the first heat transfer portion.
7. The terminal of claim 1 ,
wherein heat conductivity of the second heat transfer portion is higher than that of the first heat transfer portion.
8. A mobile terminal comprising:
a terminal body;
a display module located in the terminal body;
a printed circuit board located within the terminal body;
at least one electric device mounted on the printed circuit board;
a sealing unit coupled to the printed circuit board to shield the electric device;
a frame having a first surface and a second surface;
a first heat transfer portion being provided on the first surface of the frame, the first heat transfer portion being coupled to the sealing unit to radiate heat generated from the electric device;
a second heat transfer portion to transfer heat from the electric device to the sealing unit, the second heat transfer portion being formed on one surface within the sealing unit; and
an insulator coupled to the second surface of the frame to reduce the amount of heat transferred to the display module.
9. The terminal of claim 8 , further comprising a battery located within the terminal body,
wherein the terminal body includes a rear case and a battery cover to cover the battery and the rear case, and
wherein the printed circuit board is disposed between the rear case and the frame.
10. The terminal of claim 9 , further comprising an insulator formed on a predetermined region of an inner surface of the battery cover to prevent heat from being transferred to an outer surface of the battery cover.
11. The terminal of claim 8 , wherein heat conductivity of the second heat transfer portion is higher than that of the first heat transfer portion.
12. A mobile terminal comprising:
a terminal body;
a display module located in the terminal body;
a printed circuit board located within the terminal body;
at least one electric device mounted on the printed circuit board;
a frame;
a sealing unit coupled to the frame to shield the electric device;
a first heat transfer portion coupled to the frame to radiate heat generated from the electric device; and
a second heat transfer portion to transfer heat from the electric device to the sealing unit, the second heat transfer portion being formed on one surface within the sealing unit,
wherein the frame and the display module are arranged to provide an air gap therebetween to reduce heat transferred to the display module.
13. The terminal of claim 12 , further comprising a battery located within the terminal body,
wherein the terminal body includes a rear case and a battery cover to cover the battery and the rear case, and
wherein the printed circuit board is disposed between the rear case and the frame.
14. The terminal of claim 12 , wherein heat conductivity of the second heat transfer portion is higher than that of the first heat transfer portion.
