Abstract

A near-infrared condensing heating unit includes a frame having an open side at a side and a seat inside, and a reflecting plate disposed in the seat of the frame having an opening corresponding to the open side, and an extended semi-elliptic cross-section along an elliptic line. The near-infrared condensing heating unit further includes a lamp disposed inside the reflecting plate, with both ends mounted on the frame through sockets.

First claim

What is claimed is:

1. A near-infrared condensing heating unit comprising:
a frame having an open side at a side and a seat inside;
a reflecting plate, disposed in the seat of the frame, having an opening corresponding to the open side, and having an extended semi-elliptic cross-section along an elliptic line;
a lamp, disposed inside the reflecting plate, with both ends mounted on the frame through sockets; and
wherein heat dissipation holes are formed at the sides of the frame, through the sides except the open side, to expose an outer side of the reflecting plate.

2. The near-infrared condensing heating unit of claim 1 , wherein fitting grooves are formed at the frame, along both ends of the open side to fit both ends of the reflecting plate.

3. The near-infrared condensing heating unit of claim 1 , wherein
connecting holes are formed at corners of front and rear sides of the frame, and
the frame is, in a unit module, to be connected by connecting joints through the connecting holes.

4. The near-infrared condensing heating unit of claim 1 , wherein the reflecting plate has:
a semi-elliptic section disposed in the seat of the frame; and
an extended section extending along the elliptic line from both ends of the semi-elliptic section.

5. The near-infrared condensing heating unit of claim 1 , wherein the reflecting plate forms the elliptic line and maximizes a light-condensing ratio in a shape further extending from a semi-ellipse.

6. The near-infrared condensing heating unit of claim 1 , wherein a surface treatment is performed on the reflecting plate to increase reflectivity.

7. The near-infrared condensing heating unit of claim 6 , wherein the surface treatment is anodizing.

8. The near-infrared condensing heating unit of claim 1 , wherein the reflecting plate is formed along the elliptic line to form a light condensing area at the outside of the opening of the reflecting plate and to condense the light by reflecting light diffused from the lamp.

9. The near-infrared condensing heating unit of claim 1 , wherein the lamp is a near-infrared lamp.

10. A near-infrared condensing heater comprising:
a near-infrared condensing heating unit including a frame having an open side at a side, a seat inside, and connecting holes at the corners of front and rear sides, a reflecting plate disposed in the seat of the frame, having an opening corresponding to the open side, and having an extended semi-elliptic cross-section along an elliptic line, and a lamp disposed inside the reflecting plate, with both ends mounted on the frame through sockets; and
connecting joints connecting at least two near-infrared condensing heating units through the connecting holes.

11. The near-infrared condensing heater of claim 10 , wherein the connecting joint includes:
a first rod having one end fitted in a connection hole formed at one frame;
a second rod having one end fitted in the connection hole formed at another frame; and
a universal joint connecting the other ends of the first rod and the second rod.

12. The near-infrared condensing heater of claim 11 , wherein the first rod and the second rod are thread-fastened to the connecting holes, respectively.

13. The near-infrared condensing heater of claim 10 , wherein a plurality of near-infrared condensing heating units are arranged in a straight line or a curved line along a portion to be heated on a material, in accordance with a length, a degree of fitting in the connecting holes, and a joint function of the connecting joints.
