Abstract

A heat generator using a Carbon Nano Tube (CNT) composite material includes: an outer electrode part; an inner electrode part which faces the outer electrode part and is spaced apart from the outer electrode part at a predetermined distance; a connection part which connects the outer electrode part with the inner electrode part; and a bracket part which is disposed in the outer electrode part and the inner electrode part including the connection part to shield the outer electrode part, the inner electrode part and the connection part from each other. A surface of the connection part does not face directly the outer electrode part and the inner electrode part. The outer electrode part and the inner electrode part include electrodes having polarities different from each other.

First claim

What is claimed is:

1. A heat generator using a Carbon Nano Tube (CNT) composite material comprising:
an outer electrode part;
an inner electrode part which faces the outer electrode part and is arranged to be spaced apart from the outer electrode part at a predetermined distance;
a connection part connecting the outer electrode part with the inner electrode part; and
a bracket part disposed in the outer electrode part and the inner electrode part including the connection part and shielding the outer electrode part, the inner electrode part and the connection part so that a surface of the connection part do not face directly the outer electrode part and the inner electrode part,
wherein the outer electrode part and the inner electrode part include electrodes having polarities different from each other, and include a heat-generating area, which is heat-generated by a current flowing through a CNT composite material disposed between the outer electrode part and the inner electrode part.

2. The heat generator of claim 1 ,
wherein the outer electrode part comprises:
a front electrode part, which extends in a longitudinal direction of a vehicle; and
a front end electrode part, which is bent at and extends from an end of the front electrode part in an inner direction of the vehicle,

wherein the bracket part has a front bracket part which surrounds to shield an outer circumferential surface of the front electrode part, and
wherein the inner electrode part comprises a front counter electrode part which is parallel to the front end electrode part and spaced apart from the front end electrode part at a predetermined distance.

3. The heat generator of claim 1 ,
wherein the outer electrode part comprises:
a rear electrode part, which extends in a longitudinal direction of a vehicle; and
a rear end electrode part, which is bent at and extends from an end of the rear electrode part in an inner direction of the vehicle,

wherein the bracket part has a rear bracket part which surrounds to shield an outer circumferential surface of the rear electrode part, and
wherein the inner electrode part comprises a rear counter electrode part which is parallel to the rear end electrode part and spaced apart from the rear end electrode part at a predetermined distance.

4. The heat generator of claim 1 ,
wherein the outer electrode part has a central electrode part which extends in a longitudinal direction of a vehicle,
wherein the bracket part comprises:
a front connection bracket part which extends vertically from one end of the central electrode part in an inner direction of the vehicle;
a rear connection bracket part which extends vertically from another end of the central electrode part toward an inner direction of the vehicle; and
a central bracket part which connects the front connection bracket part with the rear connection bracket part, and

wherein the inner electrode part comprises a central counter electrode part which faces the central electrode part in the central bracket part.

5. The heat generator of claim 1 ,
wherein the heat generator includes at least two of a pair of counter electrodes comprising the outer electrode part and the inner electrode part,
wherein the heat-generating area comprises at least two heat-generating areas arranged between the pair of the counter electrodes, and
wherein current directions of any one of the plurality of heat-generating areas and another one adjacent thereto are not parallel with each other.

6. The heat generator of claim 4 ,
wherein the central counter electrode part is arranged have a slope with respect to the central electrode part.

7. The heat generator of claim 4 ,
wherein the outer electrode part has a “U” shape as a whole, and comprises a front end electrode part, a central electrode part, and a rear end electrode part.

8. The heat generator of claim 7 ,
wherein the front end electrode part and the rear end electrode part have different lengths.

9. The heat generator of claim 8 ,
wherein the front connection bracket part, the central bracket part, and the rear connection bracket part have parts of side surfaces cut.

10. The heat generator of claim 9 ,
wherein the front connection bracket part has the part of the side surface facing the front end electrode part cut,
wherein the central bracket part has the part of the side surface facing the central electrode part cut, and
wherein the rear connection bracket part has the part of the side surface facing the rear end electrode part cut.
