Description

판형 열교환기{Plate Heat Exchanger}Plate Heat Exchanger

본 발명은 판형 열교환기에 관한 것으로서, 더욱 상세하게는 흡수식 냉온수기 또는 냉동기에 사용되는 판형 열교환기에 관한 것이다.The present invention relates to a plate heat exchanger, and more particularly to a plate heat exchanger used in the absorption chiller or freezer.

흡수식냉동기에서의 열교환기는 저온의 묽은 용액과 고온의 진한용액을 열교환하여 재생기로 가는 묽은 용액을 가열하여 재생기에서 용액의 가열에 필요한 가열량을 줄여주고, 흡수기로 들어가는 고온의 진한 용액의 온도를 낮게 하여 흡수기에서의 냉각열량을 줄여줌으로써 연료소비율을 절감하고 열효율을 향상시켜준다. 한편, 이중효용 흡수식냉동기의 경우 재생기가 고온재생기와 저온재생기로 구분되어 있으므로 열교환기도 두 개를 구비한다. 고온재생기로 가는 묽은 용액과 고온재생기에서 나오는 진한 용액이 열교환 되는 것을 고온용액 열교환기, 저온재생기로 가는 묽은 용액과 저온재생기에서 나오는 진한용액이 열교환 되는 것을 저온용액 열교환기라 한다. 고온용액 열교환기의 경우 작동유체의 온도가 150 이상으로 작동온도가 상당히 높다.The heat exchanger in the absorption chiller heats the diluted solution and the hot concentrated solution to heat the diluted solution to the regenerator, reducing the amount of heating required for heating the solution in the regenerator and lowering the temperature of the hot concentrated solution entering the absorber. By reducing the heat of cooling in the absorber, it reduces fuel consumption rate and improves thermal efficiency. Meanwhile, in the dual-effect absorption chiller, since the regenerator is divided into a high temperature regenerator and a low temperature regenerator, two heat exchangers are also provided. The heat exchanger between the dilute solution going to the high temperature regenerator and the thick solution from the high temperature regenerator is called the low temperature solution heat exchanger. In the case of high temperature solution heat exchangers, the operating fluid temperature is higher than 150 and the operating temperature is quite high.

종래에는 흡수식 냉동기용 열교환기로서 주로 쉘&튜브(shell and tube)방식을 사용하였다. 그러나 쉘&튜브 방식의 열교환기는 흡수식 냉동기의 특성 상 열교환 효율이 떨어지므로, 최근에는 판형 열교환기를 채용하는 경우가 늘고 있다. Conventionally, a shell and tube method is mainly used as a heat exchanger for an absorption chiller. However, since the heat exchange efficiency of the shell & tube type heat exchanger is inferior to the characteristics of the absorption chiller, a plate-type heat exchanger has been recently adopted.

이러한 판형 열교환기의 일례로서, 한국 특허등록 제0911158호 공보에 개시된 판형 열교환기를 들 수 있다. 상기 공보에 개시된 판형 열교환기는 표면에 연속적인 요철의 엠보싱 패턴이 형성된 복수의 전열판 각각의 외측 둘레가 절곡된 후, 전열판들이 적층되고 절곡된 외측 둘레의 서로 접촉되는 부분들이 서로 용접되어 접함으로써 제조된다. 고온의 작동유체와 저온의 작동유체는 전열판들 사이에 형성되는 공간을 통하여 유동하면서 열교환 된다.An example of such a plate heat exchanger is a plate heat exchanger disclosed in Korean Patent No. 0911158. The plate heat exchanger disclosed in the above publication is manufactured by bending the outer periphery of each of the plurality of heat transfer plates on which a continuous embossed pattern of the irregularities is formed on the surface, and then laminating the heat transfer plates and welding the parts in contact with each other on the bent outer periphery. . The high temperature working fluid and the low temperature working fluid are exchanged while flowing through the space formed between the heat transfer plates.

한편, 전열판들을 모두 적층한 후에 열교환기의 높이를 원하는 높이로 맞추기 위하여 전열판들의 표면을 상하 방향으로 가압하게 되는데, 이 때 상하 전열판의 표면에 형성된 요철이 서로 맞닿으면서 변형되어, 전열판들 사이의 작동유체 유로가 균일하지 못하게 되어 열교환 성능이 저하될 우려가 있다.On the other hand, after laminating all the heat transfer plate in order to adjust the height of the heat exchanger to the desired height to press the surface of the heat transfer plate in the vertical direction, at this time, irregularities formed on the surface of the top and bottom heat transfer plate is deformed while contacting each other, between the heat transfer plate The working fluid flow path becomes uneven and there is a fear that the heat exchange performance is lowered.

또한, 종래의 판형 열교환기는 양측 단부로 갈수로 전열판들 사이의 간격이 좁아짐으로써 양측 단부에서 작동유체의 흐림이 원활하게 이루지지 못하고 정체되는 현상이 발생하여 열교환 성능이 저하되는 문제점이 있다.In addition, the conventional plate heat exchanger has a problem in that the gap between the heat transfer plates is narrowed toward both ends so that the blurring of the working fluid does not occur smoothly at both ends and the congestion occurs, thereby degrading heat exchange performance.

본 발명은 상기와 같은 종래 판형 열교환기의 문제점을 감안하여 이루어진 것으로서, 전열판들 사이의 작동 유체의 유로를 균일하게 확보함으로써 열교환 성능을 향상시킬 수 있는 판형 열교환기를 제공하는 것을 목적으로 한다.The present invention has been made in view of the problems of the conventional plate heat exchanger as described above, and an object thereof is to provide a plate heat exchanger capable of improving heat exchange performance by ensuring a uniform flow path of working fluid between heat transfer plates.

상기와 같은 본 발명의 목적은, 표면에 복수의 엠보싱 패턴이 형성되며, 서로 적층된 상태에서 접합되는 복수의 전열판을 구비하는 판형 열교환기로서, 상기 전열판들 사이의 공간에 작동유체의 유동경로가 형성되고, 상기 전열판의 폭방향으로 상기 유동경로의 좌우 양측에 스페이서가 설치된 것을 특징으로 하는 판형 열교환기를 제공함으로써 달성될 수 있다.An object of the present invention as described above is a plate heat exchanger having a plurality of embossed patterns are formed on the surface, and having a plurality of heat transfer plates joined in a stacked state, the flow path of the working fluid in the space between the heat transfer plates It is formed, it can be achieved by providing a plate heat exchanger characterized in that the spacer is provided on both left and right sides of the flow path in the width direction of the heat transfer plate.

상기 스페이서는 상기 전열판에 상기 작동유체가 유동하는 방향을 따라 연장되며, 상기 엠보싱 패턴의 높이보다 높게 형성될 수 있다.The spacer may extend along the direction in which the working fluid flows on the heat transfer plate, and may be formed higher than the height of the embossing pattern.

본 발명의 일 실시예에 따르면, 상기 전열판은 하나의 판재의 중간부를 접어서 그 내측에 상기 유동경로가 형성되도록 한 것일 수 있다.According to an embodiment of the present invention, the heat transfer plate may be to fold the middle portion of one plate member so that the flow path is formed inside.

이 경우, 상기 스페이서는 상기 판재에 소정 간격을 두고 형성한 복수의 돌출부들이 상기 판재가 접혀질 때 상측에 위치하는 돌출부들과 하측에 위치하는 돌출부들이 서로 맞닿아 형성된다.In this case, the spacer is formed by a plurality of protrusions formed at predetermined intervals on the plate material to contact the protrusions located on the upper side and the protrusions located on the lower side when the plate is folded.

본 발명의 일 실시예에 따른 판형 열교환기는, 스페이서가 전열판의 좌우 양측 단부에 설치되고, 작동유체의 유동이 스페이서들 사이에서만 이루어짐으로써, 작동유체 유동경로가 전열판의 폭방향을 따라 균일하게 유지될 수 있다. 따라서, 종래의 판형 열교환기에 비하여 작동유체들의 유동 시 저항이 작으며, 그에 따라 낮은 압력강하 특성을 가지게 되어 결과적으로 열교환 성능을 향상시킬 수 있다.Plate heat exchanger according to an embodiment of the present invention, the spacer is installed at the left and right both ends of the heat transfer plate, the flow of the working fluid is made only between the spacers, the working fluid flow path is to be maintained uniform along the width direction of the heat transfer plate Can be. Therefore, compared with the conventional plate heat exchanger, the resistance in the flow of the working fluid is small, and thus has a low pressure drop characteristic can improve the heat exchange performance as a result.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세하게 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 판형 열교환기의 단면도이다.1 is a cross-sectional view of a plate heat exchanger according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 판형 열교환기는 복수의 전열판(1)들이 소정 간격으로 적층됨으로써 형성된다. 전열판(1)의 표면에는 연속적인 요철의 엠보싱 패턴(2)이 형성된다. 전열판(1) 내부에는 고온 및 저온의 작동유체들이 유동할 수 있는 경로가 형성된다. 고온 및 저온의 작동유체들은 전열판(1) 내부의 유동경로들을 따라 반대방향으로 유동하면서 서로 열교환 된다. 상하로 적층된 전열판(1)들은 외측 둘레에서 용접됨으로써 서로 고정된다.As shown in FIG. 1, the plate heat exchanger is formed by stacking a plurality of heat transfer plates 1 at predetermined intervals. On the surface of the heat transfer plate 1, a continuous uneven embossing pattern 2 is formed. Inside the heat transfer plate 1, a path through which high and low temperature working fluids flow is formed. The high and low temperature working fluids exchange heat with each other while flowing in opposite directions along the flow paths inside the heat transfer plate 1. The heat transfer plates 1 stacked up and down are fixed to each other by welding at an outer circumference.

전열판(1)들 사이에는 간격 유지를 위한 스페이서(10)가 설치된다. 스페이서(10)의 존재로 인하여 전열판(1)들 사이에서의 작동유체들의 유동경로가 일정하게 유지될 수 있다. Spacers 10 are provided between the heat transfer plates 1 to maintain a gap. Due to the presence of the spacer 10, the flow path of the working fluids between the heat transfer plates 1 can be kept constant.

도 2에 도시된 바와 같이, 스페이서(10)는 전열판(1)의 좌우 양측 단부로부터 폭방향(도 2에서의 수평방향) 내측으로 소정 간격만큼 이격된 위치에 각각 위치하며, 화살표로 표시한 작동유체가 유동하는 방향인 전열판(1)의 길이방향(즉, 도 2에서의 수직방향)을 따라 연장된다. 엠보싱 패턴(2)은 한 쌍의 스페이서(10)들 사이의 전열판(1) 표면에 형성된다. 또한, 작동유체는 한 쌍의 스페이서(10)들 사이의 공간, 즉 엠보싱 패턴(2)이 형성되어 있는 공간에서만 유동하게 된다.As shown in FIG. 2, the spacers 10 are located at positions spaced apart by a predetermined interval from the left and right ends of the heat transfer plate 1 inward in the width direction (horizontal direction in FIG. 2), and are indicated by arrows. It extends along the longitudinal direction (ie, the vertical direction in FIG. 2) of the heat exchanger plate 1 in the direction in which the fluid flows. The embossing pattern 2 is formed on the surface of the heat transfer plate 1 between the pair of spacers 10. In addition, the working fluid flows only in the space between the pair of spacers 10, that is, in the space in which the embossing pattern 2 is formed.

이와 같이, 스페이서(10)가 전열판(1)의 좌우 양측 단부에 설치되고, 작동유체의 유동은 스페이서(10)들 사이에서만 이루어짐으로써, 작동유체 유동경로가 전열판(1)의 전체 폭방향을 따라 균일하게 유지될 수 있다. 따라서, 종래의 판형 열교환기에 비하여 작동유체들의 유동 시 저항이 작으며, 그에 따라 낮은 압력강하 특성을 가지게 된다. 또한, 전열판(1)의 좌우 양측 단부에서 작동 유체의 유동이 정체되는 소위 데드존(dead zone)의 발생이 방지된다.As such, the spacer 10 is installed at both left and right ends of the heat transfer plate 1, and the working fluid flows only between the spacers 10, so that the working fluid flow path is along the entire width direction of the heat transfer plate 1. It can be kept uniform. Therefore, compared with the conventional plate heat exchanger, the resistance in the flow of the working fluid is small, thereby having a low pressure drop characteristics. In addition, the occurrence of so-called dead zones in which the flow of the working fluid is stagnant at both left and right ends of the heat transfer plate 1 is prevented.

한편, 본 실시예에서 전열판(1)은 하나의 판재가 반으로 접혀져, 그 사이에 작동유체의 유동경로를 이루는 공간이 형성되는 방식으로 제조되며, 스페이서(10)는 전열판(1)의 표면에 길이방향으로 소정 폭을 가지는 돌출부를 가공함으로써 형성된다.Meanwhile, in the present embodiment, the heat transfer plate 1 is manufactured in such a way that one plate is folded in half, and a space forming a flow path of the working fluid is formed therebetween, and the spacer 10 is formed on the surface of the heat transfer plate 1. It is formed by processing a protrusion having a predetermined width in the longitudinal direction.

본 실시예에 따른 판형 열교환기의 제조방법을 도 3 및 도 4를 참조하여 구체적으로 설명한다.A method of manufacturing a plate heat exchanger according to the present embodiment will be described in detail with reference to FIGS. 3 and 4.

먼저, 도 3에 도시된 바와 같이, 전열판(1)을 형성하기 위하여 하나의 평평한 판재에 다수의 엠보싱 패턴(2)과, 소정 폭을 가지며 길이방향을 따라 연장된 4개의 돌출부(11, 12)를 프레스 가공한다. 이때, 돌출부(11, 12)는 엠보싱 패턴(2)보다 높은 높이를 가지도록 형성된다.First, as shown in FIG. 3, in order to form the heat transfer plate 1, a plurality of embossing patterns 2 are formed on one flat plate, and four protrusions 11 and 12 having a predetermined width and extending in the longitudinal direction. Press process. In this case, the protrusions 11 and 12 are formed to have a height higher than that of the embossing pattern 2.

다음으로, 이 판재의 중간부를 접어서 도 4와 같은 형태로 완성한다. 도 4에 도시된 바와 같이, 전열판(1)이 접혀질 때 상측에 위치하는 돌출부(11)들과, 하측에 위치하는 돌출부(12)들이 서로 접촉함으로써, 스페이서(10)를 형성한다.Next, the middle part of this sheet is folded and finished in the form as shown in FIG. As shown in FIG. 4, when the heat transfer plate 1 is folded, the protrusions 11 positioned on the upper side and the protrusions 12 positioned on the lower side contact each other, thereby forming a spacer 10.

이와 같이 접혀진 전열판(1)을 복수 개 적층한 다음, 전열판(1)들의 테두리를 용접함으로써 도 1과 같은 판형 열교환기 형태를 완성한다. 그리고, 판형 열교환기의 높이를 원하는 높이로 맞추기 위하여 전열판(1)들을 상하 방향으로 가압한다.The plurality of folded heat transfer plates 1 are stacked, and then the edges of the heat transfer plates 1 are welded to complete the plate heat exchanger as shown in FIG. 1. Then, in order to adjust the height of the plate heat exchanger to the desired height, the heat transfer plates 1 are pressed in the vertical direction.

이때, 전열판(1) 내부에 엠보싱 패턴(2)의 높이보다 높은 스페이서(10)가 존재하므로, 상하 가압에 의해서 전열판(1) 표면에 형성된 엠보싱 패턴(2)들이 서로 맞닿아 뭉개질 염려가 없다.At this time, since the spacer 10 higher than the height of the embossing pattern 2 exists inside the heat transfer plate 1, there is no fear that the embossing patterns 2 formed on the surface of the heat transfer plate 1 are pressed against each other by crushing. .

이상에서는 본 발명의 특정의 바람직한 실시예에 대하여 도시하고 또한 설명하였다. 그러나, 본 발명은 상술한 실시예에 한정되지 아니하며, 특허청구의 범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능할 것이다.The foregoing is a description of certain preferred embodiments of the present invention. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. will be.

특히, 본 실시예에서는 스페이서가 전열판을 프레스 가공하여 성형되는 것을 예로 들었으나, 스페이서를 별도의 부품으로 가공하여 전열판 내측에 설치하는 것도 가능할 것이다. 또한, 하나의 판재를 접어서 사용하는 것을 예로 들었으나, 전열판을 접지 않고 적층하여 열교환기를 형성하는 것도 가능할 것이다.In particular, in the present embodiment, the spacer is formed by pressing the heat transfer plate as an example, but it may be possible to install the inside of the heat transfer plate by processing the spacer as a separate component. In addition, although the use of one plate folded by way of example, it will be possible to form a heat exchanger by laminating the heat transfer plate without grounding.
