Description
본 발명은 고감응 적외선 방사히터에 관한 것으로서, 특히 발열체의 열용량을 최소화하고 금속발열선에서 발생한 열이 적외선 방사면 방향으로 빠르게 전달되도록 구성함으로써 열에 대한 우수한 제어 감도를 갖는 고감응 적외선 방사히터에 관한 것이다. The present invention relates to a high-sensitivity infrared radiation heater, and more particularly, to a high-sensitivity infrared radiation heater having an excellent control sensitivity to heat by minimizing the heat capacity of the heating element and configured to quickly transfer heat generated from the metal heating wire toward the infrared radiation plane. .
일반적으로, 적외선은 유기물질(고분자, 섬유, 제지, 펄프, 식품자재, 필름, 약재, 접착재, 슬러지) 및 수분에 의해 잘 흡수되며, 분자 진동준위에 영향을 주어 가열되는 현상이 나타난다. 생체도 유기물질인 천연고분자로 구성되어 있으므로 적외선을 잘 흡수하여 가온되므로 혈액순환을 좋게 하여 신진대사(효소기능증진, 독소 및 노폐물 배설)가 촉진되는 효과가 나타나 찜질방, 황토방 등이 인기를 끌고 있다. 동식물 성장촉진이나 발효숙성분야에도 활용되고 있으며, 건축자재(벽지), 고기구이판, 온열치료기 등에 다양하게 활용되고 있다. In general, infrared rays are absorbed well by organic materials (polymers, fibers, paper, pulp, food materials, films, medicines, adhesives, sludges) and moisture, and affect the molecular vibration level, resulting in heating. Since the living body is composed of natural polymers, which are organic substances, it absorbs infrared rays and warms them, thereby improving blood circulation and promoting metabolism (enzyme function, toxins and waste products excretion). . It is also used for the promotion of flora and fauna and fermentation ripening, and is used in various materials such as building materials (wallpaper), roasted meat boards, and heat treatment devices.
이와 같은 적외선의 가열 효율을 높이기 위해서는 가급적 장파장의 적외선 방사가 요구되는데 방사체 표면의 온도제어를 통하여 파장조절이 가능하며, 급속가열용 또는 대용량 산업용의 가열수단으로 사용하기 위해서는 높은 power(에너지 밀도)가 요구되므로 고온 고출력 방사체가 필요하다. 적외선 방사체로는 세라믹 분말 및 카본 종류들을 세라믹 바인더와 함께 혼합 처방한 재료를 코팅하여 사용하고 있으며 고출력의 적외선 방사체용으로 사용하기 위해서는 고온 안정성, 열전도성, 코팅막의 접착성, 적외선 방사효율 등의 특성이 우수하여야 한다. In order to improve the heating efficiency of infrared rays, infrared radiation of long wavelength is required as much as possible. The wavelength can be controlled by controlling the temperature of the radiator surface, and high power (energy density) is required to be used as a heating means for rapid heating or large-scale industrial use. High temperature, high power emitters are required as required. Infrared emitters are coated with a ceramic powder and carbon mixed with a ceramic binder, and are used for coating. For high power infrared emitters, high temperature stability, thermal conductivity, adhesion of coating film, and infrared radiation efficiency are used. This should be excellent.
현재 적외선 가열설비로는 할로겐 램프, 적외선 방사재료가 코팅된 시즈히터, 세라믹 소결관 히터 등이 상업화 되어 있으나 대량방사 시에 이들 히터의 표면온도가 700℃ 이상으로 대부분 근적외선이 방사되고 있어 유기물질에의 흡수효율이 우수한 4.5-20㎛ 파장대역의 원적외선을 고출력으로 방사시키기 어렵고 방사파의 방향제어가 불가능하여 가열특성이 좋지 않다. 현재는 저항발열선을 금속관 안에 넣고 MgO로 절연처리한 시즈히터가 주로 사용되고 있지만 부피가 커서 열용량이 크고 열전도율이 낮아 열의 감응도가 나쁠 뿐만 아니라 방사적외선의 방향제어가 불가능하여 가열체 내부공간의 온도제어가 정밀하게 요구되는 분야에는 적용이 어려운 문제점을 가지고 있다.Currently, infrared heating facilities are commercially available such as halogen lamps, sheath heaters coated with infrared radiation materials, and ceramic sintered tube heaters. It is difficult to radiate far infrared rays of 4.5-20㎛ wavelength band with high absorption efficiency with high output, and it is impossible to control the direction of radiation waves, so its heating characteristic is not good. Currently, sheath heaters with a resistance heating wire in a metal tube and insulated with MgO are mainly used.Because of their bulky size, their heat capacity is high and their thermal conductivity is low. It is difficult to apply to the field that is required precisely.
본 발명은 이상과 같은 사항을 감안하여 창출된 것으로서, 발열체의 열용량을 최소화하고 열이 빠르게 금속판에 전달되도록 함으로써 고출력 및 정밀 제어가 가능하고, 원적외선 파장의 비율이 70%가 넘는 장파장 적외선을 대량으로 방사시킬 수가 있어 피가열물의 표면과 내부의 온도 편차가 적으면서 급속 및 균일 가열이 가능한 고감응 적외선 방사히터를 제공함에 그 목적이 있다. The present invention has been made in view of the above matters, and minimizes the heat capacity of the heating element and allows the heat to be quickly transferred to the metal plate, thereby enabling high power and precise control, and allowing a large amount of long wavelength infrared rays with a ratio of far infrared rays exceeding 70%. It is an object of the present invention to provide a high-sensitivity infrared radiant heater capable of being radiated and capable of rapid and uniform heating with a small temperature deviation between the surface and the inside of the object to be heated.

The heating element 110 radiates infrared rays by generating heat by receiving power from the outside. As the heating element 110 as shown, the heating wire 110a which is located in the center and actually generates heat, the insulating material 110b which radially surrounds the heating line 110a, and the heating wire 110a and the insulating material therein.

또한, 상기 타측 금속판 부재(후면 금속판 부재)(120r)의 재질로는 열전도성이 나쁘면서 고온에서의 기계적 강도 특성이 우수한 재질의 금속이 사용된다. 그리고, 바람직하게는 이 후면 금속판 부재(120r)의 전방 표면에는 상기 발열체(110)로부터 발생된 열이 피가열물의 반대 방향으로 전달되는 것을 최대한 억제하기 위하여 열차폐용 내열재료(140)(예를 들면, 운모판)이 더 설치된다. 도 1에서 참조번호 130은 적외선 방사재료 코팅층, 150은 전,후면 금속판 부재(120f)(120r)의 결속부위를 각각 나타낸다. In addition, as the material of the other side metal plate member (rear metal plate member) 120r, a metal of a material having poor thermal conductivity and excellent mechanical strength at high temperature is used. Preferably, the heat-resistant heat-resistant material 140 (for example, on the front surface of the rear metal plate member 120r) in order to suppress as much as possible the heat generated from the heating element 110 in the opposite direction of the object to be heated. , Mica plates) are installed.

As described above, the high-sensitivity infrared radiation heater according to the present invention is configured so that the heat generated from the metal heating wire can be quickly transmitted to the metal plate coated with the radiation material to be radiated in the infrared, so the heat control sensitivity and heating efficiency are excellent. . In addition, it is possible to significantly reduce the heat capacity of the entire heating equipment is more effective for small heating equipment, it will be excellent effect when applied to the heating field that requires rapid / uniform heating and precise heat control.
