Description

열 교환관Heat exchanger tube

제1도는 본 고안의 종단면도.1 is a longitudinal sectional view of the present invention.

제2도는 제1도 A-A선 단면도.2 is a cross-sectional view taken along the line A-A of FIG.

제3도는 본 고안의 사용상태 예시단면도.Figure 3 is a cross-sectional view illustrating a state of use of the present invention.

본 고안은 내주면에 나선돌조가 돌설된 내외관 사이에 직선 돌조가 돌설된 중간관을 개재시켜서된 열교환관에 관한 것으로, 나선돌조에 의해 진열 면적을 넓힘과 함께 관 내부를 흐르는 축열매체와 피가열매체를 와류 유도하여 매체의 내외부층이 골고루 열교환이 이루어지게 하고, 내부관에 균열이 생겼을 때 확인이 용이하게 함과 동시에 축열매체와 피가열매체가 혼합되는 사고를 미연에 방지할 수 있게 한 것을 특징으로 하는 것이다.The present invention relates to a heat exchanger tube interposed between an inner and an outer tube of a spiral protrusion on an inner circumferential surface and interposed with an intermediate tube of a straight protrusion. The heat storage medium and a heated medium flowing through the inside of the tube along with an increase in the display area by the spiral protrusion. By vortexing, the inner and outer layers of the media are evenly heat exchanged, making it easy to check when a crack occurs in the inner tube, and at the same time preventing accidents in which the heat storage medium and the heated medium are mixed. It is to be done.

종래의 열교환관은 유체의 유통로가 축방향의 직선상으로 되어 있기 때문에 단위길이당 전열 면적이 좁을 뿐 아니라 축열 및 피가열매체가 직선상으로 흐름으로 해서 매체의 상하부에 온도차이가 나타나고 관내부에 스케일이 생성될 가능성이 크며 내외부관의 균열에 의하여 축열매체와 피가열매체가 혼합되어도 외부에서는 식별이 않되는 결점이 있었다.In the conventional heat exchanger tube, the flow path of the fluid is linear in the axial direction, and the heat transfer area per unit length is not only narrow, but the heat storage and the medium to be heated flow in the linear form so that temperature difference appears in the upper and lower parts of the medium. The scale is likely to be formed and there is a defect that cannot be identified from the outside even if the heat storage medium and the heated medium are mixed by the internal and external pipe cracks.

본 고안은 종래 다중관에서 나타나는 결점을 개선하고 열교환효율이 향상되도록 하기 위하여 안출한 것으로서 이를 도면에 의하여 설명하면 다음과 같다.The present invention has been made to improve the defects appearing in the conventional multi-pipe and to improve the heat exchange efficiency as described by the drawings as follows.

외부관(1)과 내부관(2) 사이에 축방향의 돌조(6)를 갖는 중간관(3)을 개재시켜서된 3중관에 있어서 외부관(1)과 내부관(2)의 내주벽에 나선돌조(4)(5)를 돌설하여서 외부관(1)과 중간관(3) 사이 및 내부관(2) 내부에 각각 나선통로(7)(8)를 형성하고 내부관(2)과 중간관(3) 사이에 협소한 축방향의 직선통로(9)가 형성되게 한 것으로 도면 중 10은 축열매체의 배출구를 표시한다.In the inner tube of the outer tube (1) and the inner tube (2) in a triple tube provided with an intermediate tube (3) having an axial protrusion (6) between the outer tube (1) and the inner tube (2). Spiral protrusions 4 and 5 are formed to form spiral passages 7 and 8 between the outer tube 1 and the intermediate tube 3 and inside the inner tube 2, respectively. A narrow axial straight passage 9 is formed between the pipes 3 and 10 in the figure indicates an outlet of the heat storage medium.

이와같은 본 고안은 외부관(1) 내에는 글리콜과 같은 축열매체를 유통시키고 내부관(2)내에는 물과 같은 피가열매체를 각각 유통시키며 중간관(3) 내부는 중공부로 두고 사용하는 것으로, 이와같은 본 고안에 의하면 내외부관(1)(2) 내주벽에 무수한 나선돌조(4)(5)가 돌설되어 있어서 종래 것에 비해 단위길이당 전열면적이 넓을 뿐 아니라 나선돌조(4)(5)에 의하여 매체유통로에 나선통로(7)(8)가 구성되어 있기 때문에 내외부 열교환 매체들이 와류 유도됨에 따라 매체의 내외부층이 골고루 뒤섞이면서 열교환이 이루어져 열교환이 현저히 향상되게 하고, 또한 부식이나 기타 원인에 의해 매체 사이의 중간벽이 균열 또는 파손되어 매체들이 내부에서 누설될 경우 중간관(3)이 개재되어 있으므로 내외매체들끼리 직접 혼합되지 못하고 직선통로(9)를 통해 외부로 누출됨에 따라 열교환매체들의 혼합사고를 미연에 방지함과 동시에 관내부의 파손상태도 즉시 확인 보수할 수 있는 효과를 나타내게 된다.The present invention is to distribute the heat storage medium such as glycol in the outer tube (1), the heated medium such as water in the inner tube (2), respectively, and to use the inside of the intermediate tube (3) as a hollow part According to the present invention, the inner and outer tubes (1) and (2) have numerous spiral protrusions (4) and (5) on the inner circumferential wall, so that the heat transfer area per unit length is wider than the conventional one, and the spiral protrusions (4) Since spiral passages (7) (8) are formed in the media channel, the internal and external heat exchange media are vortex-induced, so that the internal and external layers of the media are mixed with each other, resulting in heat exchange, which significantly improves heat exchange. If the medial wall between the media is cracked or broken due to the cause and the media leak inside, the intermediate tube 3 is interposed so that internal and external media cannot be directly mixed with each other. As a result of the leak, the mixing of the heat exchange media is prevented in advance, and at the same time, the damage state inside the pipe can be immediately confirmed and repaired.
