Abstract

A radiation structure of a mobile communication terminal having a projector which rapidly dissipates heat generated from the projector and other elements built into the terminal. The mobile communication terminal includes a projector implementing an image-projection function, and a projector cover, which is composed of a heat conductive material such that at least one inner surface thereof is brought into close contact with the projector so as to dissipate heat generated from the projector to the outside of the terminal.

Claims

1. A mobile communication terminal comprising:

a projector implementing an image-projection function; and

a projector cover comprising a heat conductive material, said projector cover being formed such that at least one inner surface thereof is brought into close contact with the projector so as to dissipate heat generated from the projector to the outside of the terminal;

wherein the image-projection function of the projector is executed when at least one exterior surface of the projector cover is moved to be exposed to a surrounding environment.

2. The mobile communication terminal according to claim 1, wherein the projector cover is coated with a heat conductive film on at least one inner surface.

3. The mobile communication terminal according to claim 2, wherein the heat conductive film comprises a graphite sheet.

4. The mobile communication terminal according to claim 2, further comprising a heat conductive member disposed between the inner surface of the projector cover and light source of the projector, said heat conductive member transferring heat generated from the light source to the projector cover.

5. The mobile communication terminal according to claim 1, wherein the inner surface of the projector cover includes a heat conductive polymer in contact with at least one surface of the projector, said heat conductive polymer transferring heat generated from the projector to the projector cover.

6. The mobile communication terminal according to claim 5, wherein the heat conductive polymer comprises at least carbon nanotubes.

7. The mobile communication terminal according to claim 1, wherein the projector cover is provided, on an outer surface thereof, with a plurality of radiating fins which receive and dissipate heat generated from the projector.

8. The mobile communication terminal according to claim 7, wherein the projector cover serves to dissipates heat generated by a heating part of an electrical component of the mobile communication terminal to an environment outside of the mobile communication terminal.

9. The mobile communication terminal according to claim 1, wherein the mobile communication terminal is a mobile phone with a pair of housings slidably coupled relative to each other in the state of facing each other.

10. The mobile communication terminal according to claim 1, wherein the projector cover has a heat conductivity greater than or equal to 70 W/mK.

11. The mobile communication terminal according to claim 1, wherein the projector cover is formed of a material selected from the group consisting of:

Fe, Mg, Al, Cu, and an amalgam.

12. The mobile communication terminal according to claim 1, wherein the mobile communication terminal is a mobile phone with a data input/output unit, a transmitting/receiving unit, and the projector mounted in a single body housing, wherein said projector protrudes from the housing and wherein heat from the projector dissipates to the outside of the housing throughout the exterior surface of a projector cover.

13. The mobile communication terminal of claim 12, wherein at least four sides of the exterior surface of said projector cover are exposed to an ambient environment.

14. The mobile communication terminal according to claim 1, wherein the mobile communication terminal is a mobile phone including a cover coupled to a terminal housing, said cover operable to open and expose the projector cover to an environment outside of the mobile phone housing.

15. The mobile communication terminal according to claim 1, wherein the image-projection function of the projector is executed when the at least one exterior surface of the projector cover is slidably moved to be exposed to the surrounding environment.

16. A system of dissipating heat generated within a mobile communication terminal having at least one optical part and at least one electrical part, comprising:

at least one of;

a heat conductive film, a heat conductive polymer, and a heat conductive member drawing heat away from at least one of the electrical and the optical part; and

a projector cover formed of a heat conductive material drawing heat away from the at least one of a heat conductive film, a heat conductive polymer, and a heat conductive member and exposing said heat to an ambient environment to dissipate said heats

wherein the image-projection function of the projector is executed when at least one exterior surface of the projector cover is moved to be exposed to a surrounding environment.

17. The system of claim 16, wherein the image-projection function of the projector is executed when the at least one exterior surface of the projector cover is slidably moved to be exposed to the surrounding environment.
