Abstract

A heat transfer medium and a heat transfer method using the same are provided. The heat transfer medium comprises a film coated with a plurality of nano particles, which absorb light incident to the film to thereby transfer heat to a target object. When nano particles are applied onto a target object, the particles are removed by etching, and when a transparent film coated thereon with the nano particles is positioned, as a mask, on a target object requiring heat transfer, and then is exposed to infrared rays, heat is transferred to a specified portion of a target object under the coated nano particles, thereby obtaining a heat transfer effect without leaving unnecessary heat generating materials.

Claims

1. A heat transfer method to a target object, the method comprising the steps of:

applying a film with a plurality of nano particles;

exposing the film coated with nano particles with light; and

transferring heat to the target object through absorption of light incident to the film by the nano particles.

2. The heat transfer method according to claim 1, wherein in the applying step, the nano particles are applied directly to the target object.

3. The heat transfer method according to claim 2, further comprising the step of removing the nano particles from the target object by etching.

4. The heat transfer method according to claim 1, wherein in the applying step, the nano particles are applied to an interlayer on the target object.

5. The heat transfer method according to claim 1, wherein in the applying step, the nano particles are applied to an infrared (IR) transparent film.

6. The heat transfer method according to claim 1, wherein in the applying step, the nano particle is Au, Cu, Ag, Ti, Al, Pd, Pt, Rh, Ir, Fe, W, Ni, or combination thereof.

7. The heat transfer method according to claim 1, wherein in the applying step, the arrangement of the nano particles is changed so as to transfer heat to a specified portion corresponding to the arrangement.

8. The heat transfer method according to claim 1, wherein in the applying step, the heat transfer is controlled in such a manner that the size of the nano particles applied is regulated such that absorbance has a maximum value at a specified wavelength.

9. The heat transfer method according to claim 1, wherein in the exposure step, the incident light is in the range of visible radiation or infrared rays.

10. The heat transfer method according to claim 1, wherein a heat transfer medium used in the heat transfer method is used in an annealing process of the film applied to a plastic or glass substrate.

11. The heat transfer method according to claim 10, wherein the film applied to the plastic or glass substrate comprises a single one or combination of organic material, metal, carbon, inorganic material.

12. The heat transfer method according to claim 10, wherein the plastic substrate is a plastic substrate coated with titanium oxide (TiO₂) paste for use in photovoltaic cells.
