Description

선형히터{Line Type Heater}Linear Heater {Line Type Heater}

본 고안은 선형히터에 관한 것으로서, 보다 상세하게는 도전성의 섬유다발에 발열선을 밀착 배치하여 피복재로 피복하고 이 피복재를 통해 통전시 병렬로 연결되는 섬유다발과 발열선에서 발생하는 열이 발산되도록 하는 선형히터에 관한 것이다.The present invention relates to a linear heater, and more specifically, the heating wire is closely disposed on the conductive fiber bundle and coated with a coating material, and the linear heat dissipating heat generated from the fiber bundle and the heating wire connected in parallel through the coating material. It is about a heater.

통상적으로, 이러한 선형히터는 전기밥솥, 전기장판, 동파방지선 등의 열원으로 사용하기 위한 것으로, 도 1 및 도 2에서와 같이 섬유다발과 발열선이 일직선으로 배치되고 이들의 외부면으로 피복재가 피복된 형상을 하고 있다. 그러나 이러한 종래기술의 선형히터는 섬유다발상으로 피복재가 피복되는 공정 중 이 섬유다발이 찌그러진 상태로 피복되면서 피복재의 두께가 불균일하게 되기 때문에 연속되는 통전시 피복이 얇은 부분에서 누전이 발생할 우려가 있어 피복재를 소정두께이상으로 두껍게 할 필요가 있었고, 발열선이 섬유다발과 일직선으로 배치되었기 때문에 길이방향으로 열팽창과 수축 등의 반복응력이 발생하여 발열선이 파단될 우려가 있으며, 제품의 용도에 따라 달라지는 저항값의 열량을 얻기위해 발열선의 재질과 굵기를 조절해야 하는 등 전반적으로 원가상승의 문제가 있었다.Typically, such a linear heater is for use as a heat source such as an electric rice cooker, electric plate, freeze protection wire, etc., as shown in Fig. 1 and 2, the fiber bundle and the heating wire is arranged in a straight line and the covering is coated on their outer surface. It has become a shape. However, the linear heater of the prior art has a fear that a short circuit may occur in a thin portion during continuous energization because the thickness of the coating material becomes uneven while the fiber bundle is covered in a crushed state during the coating process of the coating material in the form of a fiber bundle. It is necessary to thicken the coating material more than the predetermined thickness, and since the heating wire is arranged in a straight line with the fiber bundle, there is a risk that the heating wire breaks due to repeated stress such as thermal expansion and contraction in the longitudinal direction, and the resistance varies depending on the use of the product. There was a problem of cost increase in general, such as adjusting the material and thickness of the heating wire to obtain the heat value of the value.

이에, 본 고안의 목적은 이러한 문제점을 해결하고자 안출된 것으로서, 피복재가 균일한 두께로 피복되도록하며, 길이방향으로 열팽창과 수축의 반복에 따른 항복응력이 작아져 발생되는 발열선의 파단현상을 막을 수 있고, 열전달 효율이 좋으며, 저항값을 조절하기 위하여 발열선을 용도에 맞게 제작할 필요가 없어 생산원가가 절감되도록하는 등의 선형히터를 제공함에 있다.Therefore, the object of the present invention was devised to solve such a problem, to cover the coating material with a uniform thickness, and to prevent the breakage of the heating wire caused by the decrease in yield stress caused by repeated thermal expansion and contraction in the longitudinal direction. In addition, the heat transfer efficiency is good, and there is no need to manufacture a heating wire for the purpose of controlling the resistance value to provide a linear heater such as to reduce the production cost.

상기 목적을 달성하기 위한 본 고안에 따른 선형히터는 도전성의 섬유다발과 발열선이 선형적으로 밀착배치되고, 이 섬유다발과 발열선이 피복재에 의해 피복된 선형히터에 있어서, 발열선은 섬유다발의 외주면을 따라 소정의 피치간격으로 권선됨을 특징으로 한다.The linear heater according to the present invention for achieving the above object is arranged in a linear close contact with the conductive fiber bundle and the heating wire, the fiber heater and the heating wire in the linear heater coated by the coating material, the heating wire is the outer peripheral surface of the fiber bundle It is characterized in that the winding at a predetermined pitch interval.

이하, 본 고안의 구체적인 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a specific embodiment of the present invention will be described in detail.

도 3에서, 본 고안에 따른 선형히터는 발열선(1)으로 권선된 섬유다발(2)을피복재(3)로 피복한 것으로, 도전성의 섬유다발(2)은 소정의 피치간격으로 권선된 발열선(1)과 병렬로 전원에 연결되어 발열된다. 상기 발열선(1)의 권선은 섬유다발(2)의 단면을 원형으로 형성하기 위한 것이며, 권선의 형성시 피치 간격을 어느 정도로 정하는 가에 따라서 섬유다발(2)을 권선하는 발열선(1)의 길이를 조정할 수 있게된다. 한편, 어떤 물체의 저항은 전류가 흐르는 길이에 비례하고 단면적에 반비례한다. 또한, 열의 방출은 저항값에 비례한다. 결과적으로, 본 고안에 따른 선형히터가 용도에 맞는 적정한 열원으로 사용되기 위해서는 발열선(1)의 피치간격을 조절하여 전체 발열선(1)의 길이를 조정하는 것으로 가능하다.In FIG. 3, the linear heater according to the present invention covers the fiber bundle 2 wound with the heating wire 1 with the covering material 3, and the conductive fiber bundle 2 has the heating wire wound with a predetermined pitch interval ( 1) is connected to the power supply in parallel and generates heat. The winding of the heating wire (1) is to form a cross-section of the fiber bundle (2) in a circular shape, the length of the heating wire (1) for winding the fiber bundle (2) depending on how much pitch interval in the formation of the winding Will be able to adjust. On the other hand, the resistance of an object is proportional to the length of current flow and inversely proportional to the cross-sectional area. Also, the release of heat is proportional to the resistance value. As a result, in order for the linear heater according to the present invention to be used as a suitable heat source suitable for the purpose, it is possible to adjust the length of the entire heating line 1 by adjusting the pitch interval of the heating line 1.

도 4에서는, 섬유다발(2)이 발열선(1)에의해 권선되었기 때문에 피복후 피복재(3)는 일정한 두께의 원환으로 섬유다발(2)을 둘러싸게 되며, 발열선(1)은 피복재(3)의 내측에 밀착배치된다.In FIG. 4, since the fiber bundle 2 is wound by the heating wire 1, the coating material 3 after coating surrounds the fiber bundle 2 in a ring having a constant thickness, and the heating wire 1 is the coating material 3. It is placed in close contact with the inside.

본 고안에 따른 선형히터의 통전시에는 섬유다발과 병렬로 전원에 연결되는 발열선(1)이 열팽창하게 되나, 종래의 일직선으로 배치되었을때에 비해 나선형으로 배치된 발열선(1)은 피복재(3)에의해서 단위길이당 구속된 길이가 길고, 나선방향으로 팽창하므로 직선방향으로의 팽창은 섬유다발(2)과 직선으로 배치된 발열선(1)에 비하여 상당히 줄어든다.When the linear heater according to the present invention is energized, the heating wire 1 connected to the power source in parallel with the fiber bundle is thermally expanded, but the heating wire 1 arranged in a spiral shape is a covering material 3 when compared with the conventional straight line. Since the constrained length per unit length is long and expands in the helical direction, the expansion in the linear direction is considerably reduced in comparison with the fiber bundle 2 and the heating line 1 arranged in a straight line.

이상에서와 같이 본 고안의 선형히터는 섬유다발의 외주면 상으로 발열선이 권선되는 구조로 되어있어 균일한 두께로 피복될 수 있고, 길이방향으로 열팽창과 수축의 반복에 따른 항복응력이 작아져 발생되는 발열선의 파단현상을 막을 수 있으며,열전달 효율이 좋고, 저항값을 조절하기 위하여 발열선을 용도에 맞게 제작할 필요가 없어 전반적으로 생산원가가 절감되는 등의 효과를 얻는다.As described above, the linear heater of the present invention has a structure in which a heating wire is wound on the outer circumferential surface of the fiber bundle, so that the linear heater can be coated with a uniform thickness, and the yield stress caused by repeated thermal expansion and contraction in the longitudinal direction is generated. It is possible to prevent the breakage of the heating wire, the heat transfer efficiency is good, and it is not necessary to manufacture the heating wire for the purpose to control the resistance value, and the overall production cost is reduced.

이상에서 본 고안은 기재된 구체예에 대해서만 상세히 설명되었지만, 본 고안의 기술사상 범위 내에서 다양한 변형 및 수정이 가능함은 당업자에게 있어서 명백한 것이며, 이러한 변형 및 수정이 첨부됨은 실용신안등록청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications are included in the utility model registration claims. It is natural.
