Abstract

The present invention relates to a heating seat with high efficiency, and the heating seat includes a stack structure of a substrate layer, a first insulation layer, a carbon nanotube heating layer, and a second insulation layer.

First claim

1 . A heating seat with high efficiency for a vehicle, the heating seat comprising:
a substrate layer; a first insulation layer; a carbon nanotube heating layer; and a second insulation layer

2 . The heating seat of claim 1 , wherein the substrate layer comprises a metal plate formed of a material that comprises at least one selected from the group consisting of aluminum, copper, gold, silver, platinum, and a combination thereof.

3 . The heating seat of claim 1 not comprising an adhesive layer.

4 . The heating seat of claim 1 , wherein a thickness of the substrate layer ranges from about 15 μm to about 500 μm.

5 . The heating seat of claim 1 , wherein the first insulation layer and the second insulation layer comprise an inorganic insulating material.

6 . The heating seat of claim 5 , wherein the inorganic insulating material comprises at least one selected from the group consisting of LiF, BaF 2 , TiO 2 , ZnO, SiO 2 , SiC, SnO 2 , WO 3 , ZrO 2 , HfO 2 , Ta 2 O 5 , BaTiO 3 , BaZrO 3 , Al 2 O 3 , Y 2 O 3 , ZrSiO 4 , Si 3 N 4 , TiN, and a combination thereof.

7 . The heating seat of claim 1 , wherein a thickness of each of the first insulation layer and the second insulation layer ranges from about 5 μm to about 50 μm.

8 . The heating seat of claim 1 , wherein the carbon nanotube heating layer is patterned into a predetermined shape by coating a top of the substrate layer with a carbon nanotube paste by silk-screen printing.

9 . The heating seat of claim 8 , wherein the carbon nanotube is a metal-doped carbon nanotube.

10 . The heating seat of claim 8 , wherein the predetermined shape comprises a parallel pattern or a serial pattern.

11 . The heating seat of claim 10 , wherein the parallel pattern comprises
a first main pattern; a second main pattern; and at least one straight pattern that connects the first main pattern and the second main pattern.

12 . The heating seat of claim 11 , wherein a width of the straight pattern that connects the first main pattern and the second main pattern ranges from about 100 μm to about 2 mm.

13 . The heating seat of claim 10 , wherein the serial pattern comprises a first main pattern and a second main pattern, wherein at least one of the first main pattern and the second main pattern is formed in a main zigzag pattern; or further comprises a single zigzag pattern that connects the first main pattern and the second main pattern.

14 . The heating seat of claim 13 , wherein a width of the zigzag pattern that connects the first main pattern and the second main pattern ranges from about 100 μm to about 2 mm.

15 . The heating seat of claim 1 , wherein a thickness of the carbon nanotube heating layer ranges from about 5 μm to about 50 μm.

16 . The heating seat of claim 1 further comprising a power unit that is electrically connected to the carbon nanotube heating layer and induces heating of the carbon nanotube heating layer when a voltage is applied.

17 . The heating seat of claim 16 , wherein a heating temperature of the heating layer ranges from about 50° C. to about 130° C. when a voltage is applied to the power unit.
