비접촉 핀구조 전기히터{ELECTRIC HEATING UNIT}Non-Contact Pin Structure Electric Heater {ELECTRIC HEATING UNIT}

본 발명은 비접촉식 핀구조의 열매체 전기히터에 관한 것으로, 열매체가 흐르는 내부공간을 가진 관체, 관체의 내부공간에 열매체에 전기히터가 노출되지 않도록 가열체를 구성하여, 가열체 내부에 전기히터를 분해조립 가능하게 결합하고, 열매체의 흐름 유도와 가열을 위한 관체 또는 가열체 외주면에 방열판과 열매체 유도판의 구성을 특징으로 하는 비접촉 간접가열 핀구조 전기히터 가열장치에 관한 것이다The present invention relates to a heat medium electric heater of a non-contact fin structure, the tube body having an inner space through which the heat medium flows, the heating body is configured so that the electric heater is not exposed to the heat medium in the inner space of the pipe body, the electric heater is decomposed inside the heating body Non-contact indirect heating fin structure electric heater heating apparatus which is assembleably coupled, characterized in that the heat sink and the heat medium guide plate on the outer peripheral surface of the tube or heating body for flow induction and heating of the heat medium.

일반적으로 열매체를 가온시키는 전기히터는 도 2에 도시한 것(200)과 같이 열매체 입구(203a)와 출구(203b) 그리고 히터를 부착하기 위한 플랜지(203c)를 포함한 밀봉된 관체(203)와 파이프히터(201)가 고정부착된 밀폐용 플랜지(201a), 관체와 히터를 고정하기 위한 체결나사(204), 열매체 유출방지를 위한 패킹(205)으로 이루어져 있다.In general, an electric heater for warming the heat medium includes a sealed tube body 203 and a pipe including a heat medium inlet 203a and an outlet 203b and a flange 203c for attaching a heater, as shown in FIG. The heater 201 is composed of a sealing flange 201a fixedly attached, a fastening screw 204 for fixing the tube and the heater, and a packing 205 for preventing the leakage of the heat medium.

이러한 종래의 방식은 열매체가 관내에 오래 머물지 못하고 빨리 흐름으로써 열매체의 가온을 저해하였고 이를 보완하기 위하여 보다 큰 용량의 관체와 히터를 사용하게 되였으며 이에 따라 히터가 과열되어 히터의 수명이 현저히 감소 되였고, 열매체가 골고루 가열되지 않고 히터표면 부위만 과열되어 반영구적인 열매체의 수명을 현저히 감소시켰다.In this conventional method, the heating medium does not stay in the tube for a long time and flows quickly to inhibit the heating of the heating medium, and to compensate for this, a larger capacity tube and a heater are used. Accordingly, the heater is overheated and the life of the heater is significantly reduced. The heat medium was not heated evenly, but only the heater surface was overheated, which significantly reduced the life of the semi-permanent heat medium.

또한 히터가 열매체와 직접접촉하여 가열함으로 대용량의 가열장치를 얻기 위해서는 대형의 관체와 대량의 히터가 필요하고, 열매체에 의해 히터가 과열되고 부식되어 히터의 수명이 감소 되었다.In addition, in order to obtain a large-capacity heating device by heating the heater in direct contact with the heat medium, a large tube and a large amount of heater are required, and the heater life is overheated and corroded by the heat medium.

도 2의 히터(201)와 관체를 밀봉하기 위한 플랜지(201a)가 일체형으로 이루어져 있어 히터 고장시 교체 제작비용이 많이 들고, 히터를 교체하기 위해서는 가열장치의 운전을 정지하고, 열매체 또한 제거 후 교체가 가능함으로 고장시 장시간 운전을 정지함으로 가열장치를 이용한 생산 작업에 막대한 지장을 초래하였다.The heater 201 and the flange 201a for sealing the tubular body of FIG. 2 are integrally formed, so when the heater breaks down, the manufacturing cost is high, and in order to replace the heater, the operation of the heating device is stopped, and the heating medium is also removed and replaced. It is possible to stop the operation for a long time in case of failure, which caused enormous disruption to the production work using the heating device.

신개발 장치들은 소형 고효율화 추세로, 적은 공간에서 히터가 과열되지 않고, 열매체 또한 부분 과열 등 부작용없이 짧은 시간에 일정하게 가온하여 장치의 크기를 줄이고.Newly developed devices tend to be compact and highly efficient, so that the heater is not overheated in a small space, and the heat medium also warms up in a short time without side effects such as partial overheating, thereby reducing the size of the device.

히터가 열매체에 직접접촉하지 않고 가열하여 히터표면의 과열 및 부식을 방지하며, 열매체의 변질을 방지하여 히터와 열매체의 수명을 증가시고 고장빈도를 줄이며 히터와 가열체를 분리하여 유지보수 비용을 절감하고. Heater is heated without direct contact with the heating medium to prevent overheating and corrosion of the heater surface, prevents deterioration of the heating medium, increases the life of the heater and heating medium, reduces the frequency of failure, and reduces maintenance costs by separating the heater and heating body and.

히터 고장시 에도 기계의 운전을 정지하지 않고 교체수리하여 생산성을 극대화하는데 목적이 있다.In the event of a heater failure, it aims to maximize productivity by replacing and repairing the machine without stopping operation.

The contact area of the heating medium was maximized to the maximum, so that even in a small and short sized tube 103, constant heating was possible in a short time.

도 1에 도시한 나선형핀(101a)이 부착된 가열체(101)가 열매체를 가열하고 히터(102)는 가열체(101)를 가열하여 열매체와 히터(102)가 직접접촉하지 않아 히터(102)의 부식을 방지하고, 물의 2배, 오일의 15배 열전달 밀도가 높은 강재로 이루어진 가열체(101)를 가열하여 히터(102)의 과열을 방지였으며, 높은 용량의 히터(102)를 설치할 수 있으며 히터(102)와 열매체(120)가 직접접촉하지 않아 히터(102)와 열매체(120)의 수명을 현저히 증가시켰다.The heating body 101 with the spiral fin 101a shown in FIG. 1 heats the heating medium, and the heater 102 heats the heating body 101 so that the heating medium and the heater 102 do not directly contact the heater 102. ) To prevent corrosion and to prevent overheating of the heater 102 by heating a heater 101 made of steel with a high heat transfer density of twice the water and 15 times the oil. The heater 102 can be installed with a high capacity. In addition, since the heater 102 and the heat medium 120 do not directly contact each other, the lifespan of the heater 102 and the heat medium 120 is significantly increased.

또한 나선핀형 가열체(101)를 관체(103)에 부착고정하기 위한 플랜지(101b)와 일체형으로 제작하여 관체(103)와 고정하고, 히터(102)는 고정나사(106)에 의해 나선핀형 가열체(101)에 분해조립이 가능하게 조립되어 히터(102) 고장시 기계의 운전을 정지하지 않고 히터(102)만 분해교체하게 하였다. In addition, the spiral fin type heating body 101 is manufactured integrally with the flange 101b for attaching and fixing the spiral fin type heating body 101 to the tubular body 103, and is fixed to the tubular body 103, and the heater 102 is heated by the screw 106 for the spiral fin type heating. Disassembly and assembly were possible in the sieve 101 so that only the heater 102 was disassembled and replaced without stopping the operation of the machine when the heater 102 failed.

본 발명에 따르면, 히터와 열매체에 아무 이상 없이 적은 공간과 짧은 시간 내에 균일하고 일정한 가온을 하며, 가열장치의 크기를 줄이고,According to the present invention, the heater and the heating medium is uniform and constant heating in a small space and a short time without any abnormality, and reduce the size of the heating device,

히터와 열매체가 비접촉식으로 고용량 고효율의 히터를 사용할 수 있으며, 히터와 열매체의 수명을 3배 이상 현저히 증가시키며,Non-contact heater and heating medium can use high capacity and high efficiency heater, and significantly increase the life of heater and heating medium by more than 3 times,

히터 고장시 히터와 밀봉장치가 분리형 구조로 되어있어 히터만 교체하여 유지보수 비용을 절감하고, 운전을 정지하지 않고 히터교체 수리가 가능하여 생산성 향상 및 원가절감을 할 수 있다.In case of heater failure, the heater and sealing device are separated so that maintenance cost can be reduced by replacing only the heater, and heater replacement and repair can be performed without stopping the operation, thereby improving productivity and reducing costs.

본 발명은 고효율 고양질의 가열장치로써 히터와 열매체의 수명을 증가시키며 고장빈도를 줄이고, 고장수리시에도 기계의 운전을 계속할 수 있게 하여 장치의 크기를 줄이고 유지보수비용을 절감하며, 생산성을 최대화하기 위하여,
