본 발명 방열용 히타의 구성은 다음과 같다.The configuration of the heat dissipation heater of the present invention is as follows.
사용 용도에 따라 본체내부의 공간을 유지하여 본체 모양을 제작하고 기존의 전열히타 외관에 전도율이 높은 금속으로 본체 내부의 용적이나 또는 전열 히타 외관에 결합이 용이하게 잠열휜을 압출하여 전멸 히타 외관에 결합하며 상기와 같이 제작된 전열히타를 본체 내부공간에 삽입하고 밀봉하여 본체 내부에 체적에 따라 소량의 열매체를 삽입하고 본체 내부공간을 중진공이상 유지하여 완벽하게 봉합한 후 연결관으로서 연결하거나 직접 외부관에 방열휜을 부착한다.Depending on the purpose of use, the space inside the main body is manufactured to make the main body shape, and it is made of metal with high conductivity to the existing electric heater's exterior.

Description
본 발명은 방열용 히타와 이를 이용한 각종 실용 방열기기의 제조방법에 관한 것으로 더 상세하게는 주택온돌, 농촌비닐하우스, 화훼단지온실, 공간난방용 열기기등 에너지를 사용하는 모든 분야에서 사용하고 있는 방열용 히타이다.The present invention relates to a heat dissipation heater and a method for manufacturing various practical heat dissipation devices using the same. More specifically, heat dissipation used in all fields using energy, such as a house ondol, a rural vinyl house, a flower garden greenhouse, and a space heater. It is a dragon hita.
본 발명의 방열용 히타는 전열히타를 히트파이프 본체 내부에 직접 삽입하여 제작하여 방열을 극대화하고 잠열휜을 부착함으로서 열원의 급상승하는 온도를 제어하여 전열히타의 수명을 연장함은 물론 모든 방열기기 제작이 간편하여지게한 것이다.The heat dissipation heater of the present invention is produced by inserting the electric heat heater directly into the heat pipe body to maximize heat dissipation and attaching a latent heat fan to control the temperature of rising of the heat source to extend the life of the electric heat heater as well as to manufacture all the heat dissipation devices. This will make it simpler.
주지하는 바와같이 히트파이프의 원리는 모든 에너지 사용 응용 기기를 자유롭게 제작하되 그 본체의 내부를 공간으로 형성하고 공간체적에 따른 소량의 열매체를 장입하고 진공하여 밀봉한 것이다.As is well known, the principle of heat pipe is to freely manufacture all energy-using applications, but to form the inside of the main body into a space, and to charge a small amount of heat medium according to the volume of space and seal it by vacuum.
이렇게 제작된 본체의 일단만 가열하면 본체내부에 장입되어 있는 매체는 순간적으로 기체로 변하게 되고 진공권내에 초속으로 확산되어 본체 전체가 동일한 온도를 유지하는 팽창과 응축이 동력없이 반복되는 것이다.When only one end of the main body is heated in this way, the medium charged into the main body instantly turns into gas and diffuses in a vacuum zone at high speed so that the expansion and condensation of the entire body maintaining the same temperature is repeated without power.
이렇게 제작된 본체 내부일단에 전기에너지 또는 온수에너지가 통과 할 수 있는 통로를 형성하고 에너지를 통과 시키면 본체는 히타가 되고 본체 외면에 방열휜을 부분 또는 전체에 부착하면 방열면적의 확대로 많은 열량을 방열하게 하는 기술이다.Form a passage through which electric energy or hot water energy can pass through the inside of the body, and if energy passes, the body becomes a heater, and if heat radiation is attached to a part or the whole on the outside of the body, a large amount of heat can be obtained by expanding the heat dissipation area. It is a technology that allows heat dissipation.
종래 특수열선 열원 그 자체 그대로 사용하는 방열기는 방열면적이 적어 열선고온을 피할 수 없고 이로 인하여 열선의 수명단축뿐아니라 공기중산소가 동시 연소되어 공기가 탁하고 열 대류가 불량하다.The heat radiator used as a conventional special heat source heat source itself is small heat dissipation area is inevitable to avoid the high temperature of the hot wire, thereby shortening the lifespan of the heat wire as well as the simultaneous combustion of air oxygen, air turbidity and poor heat convection.
또 온수 또는 스팀 순환식 방열기는 방열기 내부전체에 열원이 지속적으로 순환되어야 하는 구성임으로 방열기 표면 온도 분포가 일정치 못하고 관 중심으로 흐르는 에너지 동력에 의해 잠열 상태를 유지한채 통과하여 효율이 저하되는 단점이 있다.In addition, the hot water or steam circulation radiator has the disadvantage that the heat source must be continuously circulated throughout the radiator, so that the surface temperature distribution of the radiator is not constant and the efficiency decreases as it passes through the latent heat state by energy power flowing through the center of the tube. have.
우리나라에서도 상기와 같은 히트파이프의 원리를 난방기기에 적용은 하고 있으나 아직은 초보단계이고 많은 부분이 좀더 개발되어야 할 실정이다.In Korea, the principle of the above heat pipe is applied to the heating device, but it is still a beginner stage, and much of the situation needs to be further developed.
예를 들면 히트파이프는 제작을 하고 있으나 자유롭게 그 구조를 제품쪽으로 발전하기 못하는 실정이고 특히 제품의 에너지를 공급하는 방법이 본체 외부에서 가열하고 있기 때문에 제대로 히트파이프의 성능도 발휘하지 못하고 효율도 저하되는 결점이 있다.For example, heat pipes are manufactured, but the structure cannot be freely developed toward the product. Especially, since the method of supplying the energy of the product is heated outside of the main body, the performance of the heat pipe is not properly exhibited and the efficiency is lowered. There is a flaw.
특히 간접열원의 효율을 높이기 위하여 히타와 본체사이에 납 또는 세라믹등으로 충진하고 있으나 이는 제품 원가 상승 요인이 발생되고 제품의 수명단축과 하자보수등이 불가능한 관계로 실용화되지 못하는 실정이다.Especially, in order to increase the efficiency of the indirect heat source, the filler is filled with lead or ceramic between the heater and the main body, but this cannot be put to practical use due to the increase of product cost and shortening of product life and repair.
본 발명은 본체 구성을 사용처에 따라 자유롭게 제작할 수 있으면서 방열부에 열전달이 균등하게 초고속으로 전달하는 방법으로서 열원을 본체내부에 직접 삽입하고 잠열휜을 설치하여 에너지 손실은 0％로 유지하여 효율을 극대화하고 본체에 연결관을 연결하거나 또는 방열휜을 간단하게 부착하여 방열면적을 확대하는 기술에 역점을 두고 본 발명을 완성하였다.The present invention can be freely manufactured according to the use of the main body configuration, while the heat transfer to the heat dissipation part uniformly at high speed as a method of directly inserting the heat source inside the main body and install a latent heat 휜 energy loss at 0% to maximize efficiency The present invention was completed with an emphasis on a technique for expanding a heat dissipation area by connecting a connector to a main body or simply attaching a heat dissipation fan.
