The present invention relates to a heating element, and more particularly, to a structure of a heating element capable of generating heat by converting predetermined energy into thermal energy and a method of manufacturing the same.

In general, the heating element is composed of a filament that is a heat generating portion, a quartz tube into which the filament is inserted, and a connecting portion connecting the filament with an external power source, and the like, and convert the electrical energy into thermal energy to generate heat.

In detail, a filament made of carbon is sealed in the central portion of the quartz tube, and the filament is connected to an external power source by the connection part. The inside of the quartz tube is filled with an inert gas such as vacuum or halogen gas, and its oxidation phenomenon is suppressed when the carbon filament is heated to a high temperature, thereby increasing the life of the heating element.

On the other hand, the carbon filament is in the shape of a spiral, plate, straight. In addition, the carbon filament is connected to the electrode simply by using a clip, and a method of employing a spring to maintain the phosphorus tension. In this manner, the carbon filament is disposed inside the quartz tube without being in contact with the quartz tube. Since the quartz tube melts or breaks at approximately 800 ° C. or higher, when the carbon filament being heated and the quartz tube come into contact with the quartz tube, the quartz tube is damaged and the life of the heating element is significantly shortened. Therefore, the contact between the carbon filament and the quartz tube is prevented by using a clip or a spring as described above.

However, the conventional heating element has a structure in which the carbon filament is tensioned by an external force thereof to prevent contact with the quartz tube. In the above structure, when the carbon filament is heated to a high temperature, the carbon filament is expanded according to its thermal expansion coefficient. Then, the carbon filament is stretched and brought into physical contact with the quartz tube, resulting in a shortened lifetime of the heating element due to damage of the quartz tube.

In addition, the carbon filament used in the conventional heating element is made of a spiral, plate, etc. as a whole, it is not easy to manufacture it. Therefore, there is a disadvantage that the manufacturing process of the heating element is complicated, and the manufacturing cost thereof is increased.

An object of the present invention is to provide a structure of a heating element and a method of manufacturing the same, in which the structure thereof is improved so that contact between the heat generating member and the tube surrounding the heat generating member can be reliably prevented.

Another object of the present invention is to provide a structure of a heating element which is easy to manufacture a heating element disposed on the heating element, and a method of manufacturing the same.

The structure of the heating element according to the present invention is a tube (tube); A heat generating member disposed in the tube; And an elastic support disposed on at least a portion of the heat generating member so that the heat generating member has elasticity on its own.

In addition, the structure of the heating element according to another aspect of the present invention includes a heat-generating member having an elastic support portion capable of generating heat and an elastic support portion providing elasticity to the elastic support portion,

The elastic support part and the elastic support part are alternately arranged so that the heat generating member has elasticity by itself.

In addition, in the structure of the heating element according to another aspect of the present invention, in the structure of the heating element including a heating member capable of generating heat by converting predetermined energy into thermal energy,

At least a portion of the heat generating member, characterized in that the elastic support for providing elasticity to the heat generating member is disposed.

In addition, the structure of the heating element according to another aspect of the present invention is a carbon heating member formed on a portion of at least one elastic support for the carbon heating member has its own elastic force; A quartz tube wrapped around the outside of the carbon heating member; And a connection part connecting the carbon heat generating member to a predetermined power source.

In addition, the method of manufacturing a heating element according to the present invention includes the steps of providing an elastic support and a heat generating member having an elastic support portion; Tensioning the heat generating member such that the heat generating member has elasticity; And fixing the heat generating member such that the heat generating member maintains elasticity.

According to the structure of the heating element and the manufacturing method thereof according to the present invention, an elastic support portion having elasticity is disposed on the heat generating member and is tensioned by a predetermined tensile force. Then, the elastic support is installed in the heating element in a tensioned state. Then, a restoring force is generated in the elastic support, and the restoring force acts on the entire heat generating member, thereby preventing the heat generating member from sagging during the heat generation of the heat generating body. Therefore, the heat generating member is stretched by the thermal expansion due to the heat generation, and is in contact with the tube, thereby preventing the heat generating member and / or the tube from being damaged or broken. Therefore, the life of the heating element provided with the heat generating member can be increased.

In addition, according to the structure of the heating element and the manufacturing method thereof, it is easy to apply to the capacity and / or the size of the heating element is installed, by adjusting the arrangement position, the number of arrangement, etc. of the elastic support formed on the heat generating member. Can be done.

In addition, according to the structure of the heating element and the manufacturing method thereof, it is easy to apply to the heat generating member and its manufacture, it is possible to facilitate the manufacture of the heating element is installed.
