When welding is easy.
상기 중간판(120)은 대략 사각형 판형상으로 형성되어 상기 상부판(110)과 일체로 형성된다.The intermediate plate 120 is formed in a substantially rectangular plate shape and is integrally formed with the upper plate 110.
상기 중간판(120)에도 대각선 방향으로 연결된 요철이 형성되는 바, 하측으로 함몰되어 연장된 형상의 연장함몰부(102)가 형성됨과 동시에 상기 연장함몰부(102)에 인접되어 상측으로 돌출된 형상의 연장돌출부(103)가 형성된다.The intermediate plate 120 is also formed with irregularities connected in a diagonal direction, which is recessed downward to form an extended recessed portion 102 having an extended shape and protruding upwardly adjacent to the extended recessed portion 102. An extended protrusion 103 of is formed.
상기와 같이 연장함몰부(102) 및 연장돌출부(103)가 연속되어 형성됨에 의해 중간판(120) 전체에는 경사지게 연속된 요철이 형성되는 것이다.As described above, since the extension recess 102 and the extension protrusion 103 are continuously formed, the intermediate plate 120 is formed to have a concave and convex continuous slope.
여기서 상기 중간판(120)에 형성된 연장함몰부(102)는 상기 상부판(110)에 연결된 연장함몰부(102)와 연결되어 상부판(110)의 연장함몰부(102)가 연장된 형상으로 형성되며, 마찬가지로 연장돌출부(103) 또한 상기 상부판(110)의 연장돌출부(103)와 연결되어 상부판(110)의 연장돌출부(103)가 연장된 형태로 형성된다.In this case, the extension recess 102 formed in the intermediate plate 120 is connected to the extension recess 102 connected to the upper plate 110 so that the extension recess 102 of the upper plate 110 is extended. Likewise, the extension protrusion 103 is also connected to the extension protrusion 103 of the upper plate 110 so that the extension protrusion 103 of the upper plate 110 is formed in an extended form.
또한 상기 중간판(120)의 양측단부 인접부에도 요철이 형성되지 않는 편평부가 형성되어 열교환판(100)을 적층하여 상호간에 용접하는 경우, 용접을 용이하게 한다. 여기서 상기 중간판(120)을 형성시키는 이유는 상기 상부판(110)의 유입공(101)과 후술하는 하부판(130) 사이에 형성되어 유체가 유동되는 상당길이(thermal length)를 증가시키고, 동시에 유체가 유동되는 전열면적을 증가시켜 열교환효율을 증가시키기 위함이다.In addition, a flat portion having unevenness is formed in the adjacent portions of both end portions of the intermediate plate 120 to facilitate the welding when the heat exchange plates 100 are stacked and welded to each other. Here, the reason for forming the intermediate plate 120 is formed between the inlet hole 101 of the upper plate 110 and the lower plate 130 to be described later to increase the considerable length of the fluid (thermal length), and at the same time This is to increase heat exchange efficiency by increasing heat transfer area through which fluid flows.
상기 하부판(130)은 상측은 직선상으로 형성되고 하측부분은 원호상으로 형성되어, 상기 상부판(110)과 대칭적인 형상을 가지는 대략 반원형의 판형상으로 구성되어 상기 중간판(120)과 일체로 형성된다.The lower plate 130 is formed in a straight line on the upper side, and the lower portion is formed in an arc shape, and is formed in a substantially semi-circular plate shape having a symmetrical shape with the upper plate 110 so as to be integrated with the intermediate plate 120. Is formed.
따라서 열교환판(100) 전체적으로는 반원형상의 판사이에 직사각형판이 삽입된 형태의 오브롱(oblong) 형상이 된다.Therefore, the heat exchange plate 100 as a whole has an oblong shape in which a rectangular plate is inserted between semi-circular plates.
상기 하부판(130)의 하단부 인접부에는 원형상으로 형성된 유로 형성용 유입공(101)이 형성된다.An inflow hole 101 for forming a flow path formed in a circular shape is formed at an adjacent portion of the lower end of the lower plate 130.
그리고 상기 하부판(130)에는 대각선 방향으로 연장된 요철이 형성된다. 즉, 하측으로 함몰되어 연장된 형상의 연장함몰부(102)가 형성됨과 동시에 상기 연장함몰부(102)에 인접되어 상측으로 돌출된 형상의 연장돌출부(103)가 형성되어, 연장함몰부(102) 및 연장돌출부(103)가 연속되어 형성됨에 의해 하부판(130) 전체에는 경사지게 연속된 요철이 형성되는 것이다.In addition, the lower plate 130 is formed with irregularities extending in a diagonal direction. That is, an extended depression portion 102 having a shape extended to be recessed downward is formed, and an extension protrusion 103 having a shape protruding upwardly adjacent to the extension depression portion 102 is formed to extend. ) And the extension protrusions 103 are formed continuously so that the concave-convex contiguous convexity is formed on the entire lower plate 130.
상기 하부판(130)에 형성된 연장함몰부(102)는 상기 중간판(120)에 연결된 연장함몰부(102)와 연결되어 중간판(120)의 연장함몰부(102)가 연장된 형상으로 형성되며, 연장돌출부(103) 또한 상기 중간판(120)의 연장돌출부(103)와 연결되어 중간판(120)의 연장돌출부(103)가 연장된 형태로 형성된다.The extended depression portion 102 formed on the lower plate 130 is connected to the extension depression portion 102 connected to the intermediate plate 120 and is formed to have an extended depression portion 102 of the intermediate plate 120. The extension protrusion 103 is also connected to the extension protrusion 103 of the intermediate plate 120 to extend the extension protrusion 103 of the intermediate plate 120.
또한 상기 하부판(130)의 원호면 인접부 및 유입공(101) 인접부에는 요철이 형성되지 않는 편평부가 형성되어 열교환판(100)을 적층하여 용접을 하는 경우 용접을 용이하게 한다.In addition, a flat portion without concavities and convexities is formed in the arc surface adjacent portion and the inlet hole 101 adjacent portion of the lower plate 130 to facilitate welding when the heat exchange plate 100 is laminated and welded.
상기의 구성에 의한 작동효과는 후술하는 바와 같다.The operation effect by the above configuration is as described later.
본 발명에 따른 열교환판(100)은 상부판(110), 중간판(120), 하부판(130)이 일체로 형성되며 대각선 방향으로 연결 형성된 연장함몰부(102) 및 연장돌출부(103)가 형성된 형태의 연속된 요철이 형성된다.In the heat exchange plate 100 according to the present invention, the upper plate 110, the intermediate plate 120, and the lower plate 130 are integrally formed, and the extension recess 102 and the extension protrusion 103 formed in a diagonal direction are formed. Continuous irregularities of the form are formed.
상기 연장함몰부(102) 및 연장돌출부(103)는 편의상 붙인 명칭이며, 판은 앞뒤가 동일한 형상으로 구성되어 판을 뒤집는 경우에는 연장돌출부(103)가 연장함몰부(102)가 되고, 연장함몰부(102)가 연장돌출부(103)가 되는 형태이다.The extension depression portion 102 and the extension protrusion 103 is a name given for convenience, and the plate is formed in the same shape of the front and rear, and when the plate is turned over, the extension protrusion 103 becomes the extension depression portion 102, the extension depression The part 102 becomes the extension protrusion part 103. As shown in FIG.
본 발명에 따른 열교환판(100)이 적층됨에 의해 열교환기가 형성되며 열교환판 사이 사이가 유체유동로가 되며, 열교환판과 열교환판이 적층되는 경우에 각각의 열교환판에 형성된 연장돌출부(102) 및 연장함몰부(103)가 상호간에 접촉됨에 의해 유체유동로에 가해지는 압력을 분산전달시킴에 의해 열교환판 자체가 왜곡되는 것이 방지된다.The heat exchanger is formed by stacking the heat exchanger plate 100 according to the present invention, and between the heat exchanger plates becomes a fluid flow path, and when the heat exchanger plate and the heat exchanger plate are stacked, the extension protrusions 102 and the extension formed on each heat exchanger plate The heat dissipation plate itself is prevented from being distorted by distributing the pressure applied to the fluid flow path by the depressions 103 being in contact with each other.
본 발명에 따른 열교환판은 상기 상부판(110) 및 하부판(130)에 형성된 유입공(101)을 통하여 유체가 유출입되는 경우, 즉, 하부판(130)의 유입공(101)을 통하여 유체가 유입되고 상부판(110)의 유입공(101)을 통하여 유체가 유출되는 경우에 상기 상부판(110)의 유입공(101)과 하부판(130)의 유입공(101) 사이의 거리가 통상 상당길이(thermal length)가 되며, 중간판(120)이 형성됨에 의해 상당길이가 길어지게 됨과 동시에 유체가 유동하는 면적인 전열면적 또한 커지게 되어 열교환 효율이 증가하게 된다.In the heat exchange plate according to the present invention, when the fluid flows in and out through the inlet hole 101 formed in the upper plate 110 and the lower plate 130, that is, the fluid flows through the inlet hole 101 of the lower plate 130. And the fluid flows out through the inlet hole 101 of the upper plate 110, the distance between the inlet hole 101 of the upper plate 110 and the inlet hole 101 of the lower plate 130 is usually a considerable length. (thermal length), the intermediate plate 120 is formed by the considerable length is long and at the same time the area of the fluid flow area is also large heat transfer efficiency is increased.
통상 교환되는 열량은 아래의 식으로 주어진다.The amount of heat normally exchanged is given by the following equation.
로 주어진다.Is given by
여기서 U는 총괄전열계수이며, A는 전열면적이고, ΔT는 온도차이다.Where U is the overall heat transfer coefficient, A is the heat transfer area, and ΔT is the temperature difference.
따라서 상기식에서 보는 바와 같이 본 발명에 따른 열교환판인 경우 중간판(120)의 형성에 의해 상당길이(thermal length)가 길어짐과 동시에 전열면적 A가 커지게 되어 열교환 효율이 증가된다.Therefore, in the heat exchanger plate according to the present invention, as shown in the above formula, a considerable length (thermal length) increases due to the formation of the intermediate plate 120 and the heat transfer area A increases, thereby increasing heat exchange efficiency.
그리고 동일한 전열면적을 가지는 원판형태의 열교환판과 비교하여 본 발명에 따른 오브롱 타입 열교환판인 경우 상당길이(thermal length)는 길고, 상당폭(thermal width)은 짧게 된다.In the case of the Olong type heat exchanger plate according to the present invention, the thermal length is long and the thermal width is shorter than that of the original heat exchanger plate having the same heat transfer area.
그런데 대향류의 흐름에서는 열교환효율을 지배적으로 좌우하는 것은 상당폭보다는 상당길이인 바, 동일한 전열면적을 가지는 경우에, 본 발명에 따른 오브롱 타입 열교환판의 열교환효율이 원판형태의 열교환판에 비하여 상대적으로 우수함을 알 수 있었으며 약 30%정도 우수함을 알 수 있었다.However, in the flow of the counter flow, the predominant influence on the heat exchange efficiency is a considerable length rather than a considerable width. In the case of having the same heat transfer area, the heat exchange efficiency of the oblong type heat exchanger plate according to the present invention is higher than that of the original heat exchanger plate. It was found to be relatively excellent and about 30% superior.
상기의 구성에 의한 본 발명은, 상부판과 하부판 사이에 중간판을 형성시킴에 의해 상당길이(thermal length) 및 전열면적이 길어지게 되어 열교환 효율이 증가된다는 효과가 있다.According to the present invention by the above configuration, by forming an intermediate plate between the upper plate and the lower plate has a significant length (thermal length) and heat transfer area is long, there is an effect that the heat exchange efficiency is increased.
그리고, 열교환판을 적층하여 열교환기를 형성시키는 경우 중간판의 직선부분의 존재에 의해 노즐 등의 커낵션을 부착하기가 용이하다는 효과가 또한 있다.In addition, when the heat exchanger is laminated to form a heat exchanger, there is also an effect that it is easy to attach a connection such as a nozzle due to the presence of a straight portion of the intermediate plate.
