Then, both parts of the terminal 230 are pressed toward the carbon heat generating body 210 in the longitudinal direction. In this case, using a press or the like can pressurize with a constant force. In addition, in order to pressurize the carbon heat generating body 210 and the terminal forming member 235 in the radial direction, the terminal portion 230 and the carbon heat generating body 210 are radially connected using the molds 41a and 41b that are split in the radial direction.

In order to couple the coupling part 250, the carbon heating element 200 may be pressurized in the radial direction as well as in the longitudinal direction to the axial direction, thereby improving the coupling force of the coupling part 250. Of course, this bonding process takes place while the carbon compound is maintained in formability before drying.

In the process of bonding, a bonding agent or the like may be applied to the surface to be bonded so as to prevent a defect due to the bonding force of the coupling part 250 and thermal expansion. Thus, the carbon heating element 200 as shown in FIG. 2 (e) is formed.

Second Embodiment

A method of manufacturing a coil-shaped carbon heating element and a heating lamp having a carbon heating element according to the second embodiment of the present invention will be described in detail with reference to FIGS. 5 to 10 as follows.

5 is a perspective view of a heating lamp according to an embodiment of the present invention, Figure 6 is a schematic view for explaining an embodiment of the process of manufacturing the coil-shaped carbon heating element of Figure 5, Figure 7 (a) to Figure 7 (c) is a schematic diagram showing various embodiments of the cross-sectional shape of the coil-shaped carbon heating element, Figure 8 is a schematic diagram showing an example of the carbon heating element with different pitches of the coil, Figures 9 (a) to 9 (c) 10 is a temperature curve when the pitches of the coils are the same and the pitches of the coils are different, and FIG. 10 is a block diagram illustrating a manufacturing process of an embodiment of the present invention.

The heat generating lamp 100 according to the present invention, as shown in Figure 5, is composed of a carbon heating element 200 and the glass tube (300).

The carbon heating element 200 includes a carbon heating body 210 and a terminal unit 230 that can supply power to the carbon heating body 210.

The carbon heating body 210 is preferably composed of a carbon compound made of a binder for coupling the carbon component and the carbon component such that resistance is generated by electric current when heat is supplied from the outside to generate heat. Since the components of the carbon compound and the like are not important parts of the present invention, detailed description thereof will be omitted. The carbon exothermic body 210 is molded into a shape having a constant cross section by pressing the mixed carbon compound using an extrusion means 290 such as an extruder.

As illustrated in FIGS. 7A to 7C, the carbon heating body 210 may have various cross-sectional shapes as necessary. The cross section of the carbon heating body 210 may include, for example, a circle, a trapezoid, a rectangle, an ellipse, and the like. This cross-sectional shape is selected in consideration of the use of the extrusion means 200, the amount of heat generated, the pitch source of the coil shape, the size of the cross section, the degree of flexibility of the carbon compound, the density of the carbon compound and the like. That is, the carbon heating body 210 is formed in a shape bent in a coil shape, the deformation of the inner and outer sides of the coil shape is different in the process of forming or firing the carbon heating element 200 in the coil shape.

The terminal unit 230 is provided at both ends of the carbon heating body 210 to supply power to the carbon heating body 210. The terminal unit 230 includes a conductor (not shown) that supplies power from the outside, and the conductor supplies power to the carbon heating body 210 from the outside. The conductor includes, in one embodiment, tungsten, molybdenum as an electrically conductive material.

In addition, the heat generating lamp 100 according to the present invention is configured to accommodate the carbon heating element 200 in the glass tube 300.

That is, as shown in FIG. 5, the carbon heating element 200 is accommodated in the glass tube 300 to electrically connect the external lead wires 243 and the terminal portion 230 by the thin terminals 245 at both ends of the glass tube 300. Connect Then, both ends of the glass tube 300 are sealed to form a sealing portion 310 to block the inside and the outside of the glass tube 300 to make the inside of the glass tube 300 vacuum to complete the heating lamp 100.

Hereinafter, a manufacturing process of the coil-shaped carbon heating element and the heating lamp 100 according to the present invention having such a configuration will be described in detail with reference to FIGS. 6 and 10.

First, a carbon compound is blended at a predetermined ratio to form a carbon compound (S410). Such carbon compounds have the advantage that they can be advantageous in molding to produce a variety of shapes.

Next, the carbon compound is extruded to press the carbon compound 51 stored in the storage tank 53 through an extrusion means 290 such as an extruder to form a constant cross section (S420). Here, the extrusion means 290 has a nozzle 293 through which the carbon compound 51 is discharged, as shown in the partial enlarged view of FIG. 6, which nozzle 293 corresponds to the diameter of the mandrel 270. It is desirable to have curvature (see “Rx” in FIG. 6). The reason for this is that the portion of the carbon compound contacting the mandrel 270 in the process of forming along the mandrel 270 (inner diameter side of the coil shape, see “Ri” in FIG. 6) generally tends to be compressed and the mandrel 270 This is because a part far away from the coil (outer diameter side of the coil shape, see “Ro” in FIG. 6) tends to be generally stretched. In the same carbon compound, the compressed portion and the stretched portion may be present so that the density of the carbon compound may be different. Thus, in order to minimize the difference in density, the carbon compound 51 is extruded into a shape that is the same as or similar to the outer diameter of the mandrel 270 at the nozzle 293 discharged from the extrusion means 290. The carbon compound 51 discharged from the nozzle 293 may be molded while being guided along the outer circumference of the mandrel 270 while being discharged with a predetermined radius to maintain uniformity of quality and improve product reliability and at the same time, Can be extended.

The extruded carbon compound is guided along the outer circumferential surface of the mandrel 270 moving while rotating to form a coil shape (S430). That is, the outer diameter of the mandrel 270 becomes the inner diameter of the coil-shaped carbon heating element 200. In this process, the rotational speed or the moving speed of the mandrel 270 is controlled based on the pitch of the carbon heating element 200, the amount of heat generated, and the like based on the discharge speed of the carbon compound formed and discharged from the extrusion means 290. Is controlled.

The coil pitch of the carbon heating element 200 may be changed by controlling the rotation speed or the moving speed of the mandrel 270. That is, for example, as shown in FIG. 8, the pitch (see “P2” in FIG. 8) of both end regions of the carbon heating element 200 may be shorter than the pitch in the central region (see “P1” in FIG. 8). have.

When the pitch of the coil-shaped carbon heating element 200 is the same over the entire length and the temperature curve showing the temperature over the entire length when the pitch is different as shown in FIG. ) That is, FIG. 10 (a) is a temperature curve when the coil pitches of the carbon heating elements 200 are the same, and FIG. 10 (b) is a temperature curve when the coil pitches of the carbon heating elements 200 are small at both ends. The temperature curve of FIG. 10 (a) is formed at a high temperature (see “Ty”) in the central region, and the temperature curve of FIG. 10 (b) is closer to both ends than the temperature (not shown) in the central region. It can be seen that the temperature of (see "T2") is higher and the temperature distribution as a whole is more uniform than in Fig. 10 (a). As such, by changing the rotational speed or the moving speed of the mandrel 270, a carbon heating element 200 that can be applied to various applications can be manufactured very simply and conveniently.

Next, when the carbon heating element 200 formed along the outer circumferential direction of the mandrel 270 is dried to some extent, the mandrel 270 is removed from the carbon compound (S440). Here, the mandrel 270 may include a structure in which the outer diameter decreases when the shaft portion is rotated as necessary.

Here, before the carbon heating element 200 is fired, the terminal portion 230 is formed (a portion to be modified later) at the end of the carbon heating element 200 (S445). Thus, the coupling between the carbon heating element 200 and the terminal 230 may be very solid and stable.

Next, the carbon heating element 200 proceeds to the firing process (S470). The carbon heating element 200 is fired by applying heat to the molded carbon heating element 200 (S450). In this case, the carbon heating element 200 may be supported by using a jig (not shown) which may minimize deformation of the carbon heating element 200.

The calcined carbon heating element 200 is accommodated in the glass tube 300, and forms a sealing portion 310 in which both ends of the glass tube 300 are sealed, and when the inside of the glass tube 300 is vacuumed, the heating lamp 100 is It is made (S460).

Therefore, according to the present invention, the shape of the carbon heating element can be very simply and easily molded into a coil shape or the like. In addition, the pitch of the coil can be variously formed, thereby increasing the range in which the carbon heating element is applied.

The above-described embodiment is one embodiment and the present invention can of course be made in various embodiments.

The above-described embodiment is one embodiment and the present invention can of course be made in various embodiments.
