일반적으로 전동차의 난방장치로는 전기 난방기가 주로 사용되고, 이러한 전기 난방기는 히팅코일과 난방용 관으로 구성되어 있다.In general, an electric heater is mainly used as a heating device of an electric vehicle, and the electric heater is composed of a heating coil and a heating tube.

상기 전기 난방기는 탑승자가 앉게 되는 의자의 아래부분에 설치되는 것이 보통인데, 경우에 따라서는 전기 난방기로부터 분출되는 고열의 내부공기에 의해 탑승자가 뜨거움을 느끼는 경우가 있다.The electric heater is generally installed in the lower part of the chair on which the occupant sits, and in some cases, the occupant may feel hot by the high-temperature internal air emitted from the electric heater.

즉, 종래의 전기 난방기는 220V 혹은 440V, 1,050W의 전력을 사용할 때에 온도가 280∼290℃까지 올라가기 때문에 고열로 인한 피부 손상이나 화재의 위험으로부터 자유로울 수가 없었다.That is, the conventional electric heater can not be free from the risk of skin damage or fire due to high heat because the temperature rises to 280 ~ 290 ℃ when using 220V or 440V, 1,050W power.

또한, 난방용 관은 오랜 기간동안 사용할 경우에 부식이 발생할 수 있고 내구성이 현저하게 저하되는 문제점이 있었다.In addition, the heating tube has a problem that corrosion may occur and durability is significantly reduced when used for a long time.

한편, 종래의 전기 난방기는 논란이 되고 있는 전자파 및 반사열을 방출하기 때문에 인체에 유해하고 난방효율이 떨어지게 되는 문제점이 있다.On the other hand, the conventional electric heater is harmful to the human body because it emits controversial electromagnetic waves and reflected heat, there is a problem that the heating efficiency is lowered.

이하, 본 발명에 따른 철도차량용 전기 난방기는 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, an electric heater for a railway vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 철도차량용 전기난방기의 정면도이고, 도 2는 본 발명에 따른 철도차량용 전기난방기의 저면도이며, 도 3은 도 1의 A-A선에 따른 단면도이다.1 is a front view of an electric heater for a railway vehicle according to the present invention, Figure 2 is a bottom view of the electric heater for a railway vehicle according to the invention, Figure 3 is a cross-sectional view taken along the line A-A of FIG.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 철도차량용 전기 난방기는 외형상으로 보아 히터부와 케이스부로 구분되며, 상기 히터부는 애자와 같은 별도의 절연부재위에 고정하여 전원이 들어가도 외부에 미치는 영향이 전혀 발생하지 않도록 조립된다.As shown in Figures 1 to 3, the electric vehicle for a railway vehicle according to the present invention is divided into a heater and a case part in terms of its appearance, and the heater part is fixed to a separate insulating member such as an insulator, even if power is supplied to the outside. It is assembled so that no impact occurs.

히터부는 크게 스테인리스 및 인코로일 강관으로 제작된 내측파이프(10)와 외측파이프(20)로 구성되며, 상기 내측파이프(10) 및 외측파이프(20)는 클램프(43)에 의해 절연부재(23)를 매개로 제 1지지판(40)에 고정되고, 상기 외측파이프(20)는 클램프(44)에 의해 절연부재(25)를 매개로 제 2지지판(45)에 고정된다.The heater part is mainly composed of an inner pipe 10 and an outer pipe 20 made of stainless steel and an incoloil steel pipe, and the inner pipe 10 and the outer pipe 20 are insulated by a clamp 43. It is fixed to the first support plate 40 via), the outer pipe 20 is fixed to the second support plate 45 via the insulating member 25 by the clamp (44).

또한, 상기 내측파이프(10) 및 외측파이프(20)는 그 내부 중앙에 히팅코일(50)이 삽입되어 있고, 파이프 내부의 남은 공간에는 분말형 절연재료인 충진제가 채워진다. 이때 충진제는 열전도성이 좋고 내열성이 높으며 전기 절연성이 특히 우수한 분말로서 히팅코일(50)과 화학적으로 반응하지 않고 히팅코일(50)에 무리한 영향이 없는 물질을 사용해야 하는 바, 바람직한 것으로 산화마그네슘(MgO)을 예로서 들 수 있다.In addition, the heating pipe 50 is inserted in the inner center of the inner pipe 10 and the outer pipe 20, and the remaining space inside the pipe is filled with a filler of powder type insulating material. At this time, the filler is a powder having good thermal conductivity, high heat resistance, and particularly excellent electrical insulation, and should be made of a material that does not chemically react with the heating coil 50 and does not unreasonably affect the heating coil 50. MgO is preferable. ) Is an example.

상기 히팅코일(50)은 코일 상태로 감을 때는 그 직경 피치가 균일하고 파이프(10)(20)의 한쪽으로 치우치지 않아야 하며, 파이프(10)(20)의 가열부 전장에 걸쳐 균일하게 분포된 형태로서 히팅코일(50)은 이음매가 없어야 한다.When the heating coil 50 is wound in a coil state, its diameter pitch is uniform and should not be biased to one side of the pipes 10 and 20, and the heating coil 50 is uniformly distributed over the entire heating section of the pipes 10 and 20. As a form, the heating coil 50 should be seamless.

상기 히팅코일(50)의 단부는 터미널볼트(70)에 삽입되고 상기 터미널볼트(70)는 파이프의 개방단부에 설치된 특수너트(75)에 결합된다. 상기 특수너트(75)는 리드 와이어(30)에 의해 외부전원단자(80)에 연결되어 전기를 통전시킨다.An end of the heating coil 50 is inserted into the terminal bolt 70 and the terminal bolt 70 is coupled to a special nut 75 installed at the open end of the pipe. The special nut 75 is connected to the external power terminal 80 by the lead wire 30 to conduct electricity.

또한, 상기 내측파이프(10) 및 외측파이프(20)의 외주면 전체에 세라믹층(90)이 도포된다.In addition, the ceramic layer 90 is applied to the entire outer circumferential surface of the inner pipe 10 and the outer pipe 20.

이와 같이, 난방기의 파이프에 세라믹층을 도포하게 되면 히터부의 표면온도가 세라믹을 도포하지 않았을 때보다 약 40∼50℃ 정도 내려가서 240∼250℃를 유지하게 되며, 원적외선 히터 기능으로 체내에서 느끼는 체감 온도가 따뜻하게 느껴진다.In this way, when the ceramic layer is applied to the pipe of the heater, the surface temperature of the heater portion is lowered by about 40 to 50 ° C. and maintained at 240 to 250 ° C. than when the ceramic is not applied, and the body feels in the body by the far-infrared heater function. The temperature feels warm.

여기서 원적외선은 적외선 중 파장이 긴 것을 말하는데, 눈에 보이지 않고물질에 잘 흡수되며 유기화합물 분자에 대한 공진(共振) 및 공명(共鳴) 작용이 강한 것이 특징으로 알려져 있다. 또 빛은 일반적으로 파장이 짧으면 반사가 잘 되고, 파장이 길면 물체에 도달했을 때 잘 흡수되는 성질이 있으므로 침투력이 강해서 사람의 몸도 이 원적외선을 쐬면 따뜻해진다. 예를 들어 30℃의 물속에서는 따뜻한 기운을 거의 느끼지 못하지만, 같은 온도의 햇볕을 쐬고 앉아 있으면 따스함을 느낄 수 있는데 그 이유는 햇볕 속에 포함되어 있는 원적외선이 피부 깊숙이 침투하여 열을 만들기 때문이다.Here, far infrared rays are long wavelengths of infrared rays, which are invisible and well absorbed by materials, and are known to have strong resonance and resonance effects on organic compound molecules. In addition, light generally reflects well when the wavelength is short and absorbs well when it reaches an object because the wavelength is long, so the penetration is strong and the human body also gets warm when it emits this far infrared. For example, you can hardly feel the warm energy in the water at 30 ℃, but sitting in the sun at the same temperature can feel warm because the infrared rays contained in the sun penetrates deep into the skin to create heat.

이러한 원적외선의 열작용은 각종 질병의 원인이 되는 세균을 없애는 데 도움이 되고, 모세혈관을 확장시켜 혈액순환과 세포조직 생성에 도움을 준다. 또 세포를 구성하는 수분과 단백질 분자에 닿으면 세포를 1분에 2,000번씩 미세하게 흔들어줌으로써 세포조직을 활성화하여 노화방지, 신진대사 촉진, 만성피로 등 각종 성인병 예방에 효과가 있다.This far-infrared heat action helps to eliminate bacteria that cause various diseases, and expands capillaries to help blood circulation and cell tissue generation. In addition, by touching the water and protein molecules that make up the cells, the cells are shaken finely 2,000 times per minute to activate cell tissue, which is effective in preventing various adult diseases such as aging, promoting metabolism, and chronic fatigue.

그밖에 원적외선의 작용으로서 알려진 것으로는 발한작용 촉진, 통증완화, 중금속 제거, 숙면, 탈취, 방균, 곰팡이 번식방지, 제습, 공기정화 등의 효과가 있다.In addition, known as the action of far infrared rays have the effect of promoting sweating, pain relief, heavy metal removal, sleep, deodorization, antibacterial, mold growth prevention, dehumidification, air purification.

종래의 히터는 상기와 같은 효과를 발휘하는 원적외선 히터 기능을 하지 못해 체내에서 따뜻한 온도를 느끼지 못하고 피부에서만 느낄 수 있었으나 절연체의 표면에 세라믹층을 도포한 본 발명에 따른 히터는 피부에서 온도 반응이 일어나지 않고 피부 깊숙히 스며 들기 때문에 발열체 표면온도가 낮더라도 체내에서 느끼는 따뜻함은 배로 증가하는 것이다.Conventional heaters do not function as a far-infrared heater exhibiting the above effects, but did not feel the warm temperature in the body, but only on the skin, but the heater according to the present invention coated a ceramic layer on the surface of the insulator does not cause a temperature reaction in the skin Because it penetrates deep into the skin, even if the heating element surface temperature is low, the warmth felt in the body doubles.

본 발명에서 사용하는 원적외선을 방사하는 세라믹의 성분 등은 특별히 한정하지 않으며 시중에서 용이하게 구득가능한 것이다. 본 발명의 전기 난방기 파이프에 코팅되는 바람직한 세라믹성분 및 배합비는 다음과 같다. 성분비는 중량기준이다.The component of the ceramic that emits far-infrared rays used in the present invention is not particularly limited and can be easily obtained on the market.

상기 성분 중 실리콘은 경화되어 상기 세라믹 성분을 파이프 표면에 고착 시키는 일종의 바인더(BINDER)역할을 하는 것이며, 알콜은 점도조절제이다.Of the components, silicone is a kind of binder (BINDER) that is hardened to fix the ceramic component to the pipe surface, alcohol is a viscosity modifier.
