본 발명은 순환유로가 구비된 판형 열교환기에 관한 것으로서, 보다 상세히는 판형 열교환기의 외각 모서리부에서 열매체의 흐름이 정체되는 사각지대 현상을 해소하여 열교환효율을 향상시키는 순환유로가 구비된 판형 열교환기에 관한 것이다. The present invention relates to a plate heat exchanger having a circulation flow path, and more particularly, to a plate heat exchanger having a circulation flow path to improve heat exchange efficiency by eliminating the blind spot phenomenon in which the heat flow is stagnated at the outer edge of the plate heat exchanger. It is about.

일반적으로, 판형 열교환기는 파형(波型)으로 가공한 열교환판을 일정한 간격으로 여러 장을 적층하여 조립된 열교환기의 일종으로, 상기의 열교환판은 일정한 패턴의 전열유로(Herringbone) 및 외측 모서리부에 가열/피가열 열매체가 유입 또는 유출되는 포트홀이 형성되어 있다.In general, a plate heat exchanger is a kind of heat exchanger assembled by stacking a plurality of heat exchanger plates processed into a wave at regular intervals, and the heat exchanger plate has a predetermined pattern of a herringbone and an outer edge portion. A port hole is formed in which the heated / heated heating medium flows in or out.

상기와 같은 판형 열교환기에 관한 종래의 기술로는 국내공개특허 제:2003-71249호의 '판형 열교환기' 이외에도 다수의 건으로 공지된 바에 있으며, 구체적인 설명은 생략하기로 한다.The conventional technology related to the plate heat exchanger as described above is known in a number of cases in addition to the 'plate heat exchanger' of the Korean Patent Publication No. 2003-71249, and a detailed description thereof will be omitted.

한편 상기의 종래기술에 따른 판형 열교환기의 열교환판을 도 1을 참조하여 보다 구체적으로 살펴보면 다음과 같다. 도 1은 종래의 기술에 따른 판형 열교환기의 열교환판을 예시한 사시도이다. 상기 도 1을 참조하면, 종래의 기술에 따른 판형 열교환기는 다단으로 적층되는 열교환판(1)의 양측 모서리부 중앙에 포트홀(3)을 가지는 포트구역(4)이 형성되어 있어서, 상기 포트구역(4)으로 유입된 가열/피가열 열매체가 전열유로(2)를 따라 흐르면서 열교환하도록 이루어진다.Meanwhile, the heat exchange plate of the plate heat exchanger according to the related art will be described in more detail with reference to FIG. 1. 1 is a perspective view illustrating a heat exchange plate of a plate heat exchanger according to the related art. Referring to FIG. 1, the plate heat exchanger according to the related art has a port region 4 having a port hole 3 in the center of both edges of the heat exchanger plate 1 stacked in multiple stages. The heated / heated heating medium introduced into 4) is made to exchange heat while flowing along the heat transfer path 2.

하지만, 상기의 열교환판의 외각 모서리 즉, 상기 포트구역(4)의 외측 가장자리부에서는 열매체의 흐름이 원활하지 못할 뿐만 아니라 열매체의 흐름이 국부적으로 정체되는 등, 판형 열교환기의 열교환 사각지대로 작용하였다. 이로 인해 판형 열교환기의 열교환효율이 저하되는 단점과, 상기 판형 열교환기의 모서리부위가 고온 또는 고압, 고압으로 공급되는 열매체의 영향으로 열 집중현상이 발생함은 물론 열교환판의 열적 변형을 유발하게 되며, 쉽게 손상 및 파손되는 등, 판형 열교환기의 수명이 단축되는 문제점이 있었다.However, at the outer edge of the heat exchange plate, that is, the outer edge of the port region 4, the heat medium flows not only smoothly, but also the heat medium flows locally, thereby acting as a heat exchange blind spot of the plate heat exchanger. It was. As a result, the heat exchange efficiency of the plate heat exchanger is deteriorated, and a heat concentration phenomenon occurs as well as thermal deformation of the heat exchanger plate due to the influence of the heat medium supplied at the high temperature, high pressure, or high pressure of the edge of the plate heat exchanger. There is a problem that the life of the plate heat exchanger is shortened, such as being easily damaged and broken.

또한 상기의 도면에서처럼, 상기 열교환판의 포트구역에 다른 열교환판과의 간격을 유지하기 위한 돌출부(5)를 형성하였지만, 상기의 돌출부(5)로 인해 열매체의 흐름이 더욱더 정체됨은 물론 상기와 같은 문제점들이 가중되는 원인으로 작용하였던 것이다.In addition, as shown in the above figure, although the protrusions 5 are formed in the port area of the heat exchange plate to maintain a gap with other heat exchange plates, the flow of the heat medium is further stagnant due to the protrusions 5 as well. The problem was the cause of the aggravation.

본 발명에서는 판형 열교환기의 외가 모서리부를 따라 순환유로를 형성함으로써, 포트홀로 유입 및 유출되는 가열/피가열 열매체가 전열유로는 물론 포트구역의 주변 특히, 모서리부를 따라 원활하게 순환되도록 하여 열교환효율을 향상시키는데 목적이 있다.In the present invention, by forming a circulating flow path along the outer edge of the plate heat exchanger, the heated / heated heat medium flowing into and out of the port hole is smoothly circulated along the periphery of the port area, as well as the corner of the heat transfer, thereby improving heat exchange efficiency. The purpose is to improve.

본 발명은, 다단으로 적층된 열교환판의 양측에 전열유로의 포트구역을 형성하여서 된 순환유로가 구비된 판형 열교환기에 있어서, 상기 열교환판은 상기 포트구역의 외측 모서리부를 따라 순환유로가 형성된 구성임을 특징으로 하는 순환유로가 구비된 판형 열교환기를 제안한다.The present invention is a plate heat exchanger having a circulating flow path formed by forming a port section of the heat transfer flow path on both sides of the heat exchanger plate stacked in multiple stages, wherein the heat exchange plate is configured to have a circulation flow path formed along the outer edge of the port area. We propose a plate heat exchanger equipped with a circulating flow path.

본 발명의 순환유로가 구비된 판형 열교환기는 열교환판의 외측 모서리부를 따라 순환유로를 형성함으로써, 판형 열교환기의 모서리부에 발생하는 열교환의 사각지대 현상을 해소하여 판형 열교환기의 열교환효율을 극대화시켜 성능을 향상시키는 효과가 있다.The plate heat exchanger provided with the circulation passage of the present invention forms a circulation passage along the outer edge of the heat exchange plate, thereby eliminating the blind spot phenomenon of heat exchange occurring at the edge of the plate heat exchanger to maximize the heat exchange efficiency of the plate heat exchanger. This has the effect of improving performance.

그리고 본 발명은 판형 열교환기의 외각 모서리부에서 가열/피가열 열매체가 정체됨으로 인한 열 집중현상을 해소하여 열교환판의 변형 및 손상을 방지함은 물 론 열교환기의 수명을 현저히 연장할 수 있으며, 탁월한 안전성을 제공하는 효과가 있다.In addition, the present invention solves the heat concentration phenomenon due to stagnation of the heated / heated heating medium at the outer edges of the plate heat exchanger, thereby preventing deformation and damage of the heat exchanger plate, as well as significantly extending the life of the heat exchanger. It has the effect of providing excellent safety.

First, in the plate heat exchanger 100 of the present invention, the heat exchange plates 10 having the heat transfer paths 12 are stacked in multiple stages, and the cover 30 is coupled to the upper and lower portions of the heat exchange plate 10. The heat exchange plate 10 has heat transfer paths 12 repeatedly formed at regular intervals, and a port area 14 having port holes 16 is formed at both corners thereof, and thus the heat transfer paths 10 are formed in the port area 14. 12) is connected.

즉, 상기 열교환판(10)은 일측의 포트홀(16)로 유입된 외부의 가열/피가열 열매체가 각 층의 포트구역(14)을 거쳐 전열유로(12)를 따라 흐르면서 상호 열교환된 후, 타측의 포트구역(14) 및 포트홀(16)을 통해 외부로 유출된다. 여기서, 상기의 열교환판(10)은 외각 모서리부가 둥글게 형성되며, 상기 모서리부 중앙부에 포트구역(14) 및 포트홀(16)이 마련된다. 아울러 상기 전열유로(12)는 열교환효율을 향상시키기 위해 일정한 각도로 형성되어 있다.That is, the heat exchange plate 10 is heat exchanged to the outside of the heating / heated material flowed into the port hole 16 on one side through the heat transfer path 12 through the port region 14 of each layer, and then the other side, It flows out through the port region 14 and the port hole 16 of the. Here, the heat exchange plate 10 is formed with a rounded outer corner portion, the port region 14 and the port hole 16 is provided in the center of the corner portion.

특히, 본 발명의 판형 열교환기(100)는 상기 포트구역(14)의 외측 모서리부를 따라 순환유로(20)가 형성된다. 상기 순환유로(20)는 포트구역(14)의 일측에서부터 외측 모서리부 둘레를 따라 형성되고 인접한 전열유로(12')와 선택적으로 연결되어 있어서, 상기 포트구역(14)의 열매체가 전열유로(12)는 물론 모서리부의 사각지대로도 흐르게 된다. In particular, the plate heat exchanger 100 of the present invention is formed with a circulation passage 20 along the outer edge of the port region (14). The circulation passage 20 is formed along one of the outer edges from one side of the port region 14 and is selectively connected to an adjacent heat transfer passage 12 ′ so that the heat medium of the port region 14 is transferred to the heat transfer passage 12. ), Of course, flows to the corner of the corner.

즉, 상기 포트구역(14)의 가열/피가열 열매체가 전열유로(12)로 흐름과 동시에 순환유로(20)를 따라 모서리부를 선회하면서 원활하게 열교환이 이루어지도록 한 것이다. 이는 상기 열교환판(10)의 모서리부에서 열매체의 흐름이 정체되는 사각지대 현상을 방지함은 물론 열교환 효율을 한층더 향상시킬 수가 있다. That is, the heated / heated heating medium of the port region 14 flows to the heat transfer path 12 and at the same time rotates an edge portion along the circulation flow path 20 so that heat exchange is performed smoothly. This can prevent the blind spot phenomenon in which the flow of the heat medium is stagnant at the corners of the heat exchange plate 10 as well as further improve the heat exchange efficiency.

아울러, 상기 순환유로(20)는 열교환판(10)의 구조에 따라 위로 볼록하거나 아래로 오목하게 형성된다. 이는 상기 판형 열교환기의 적용 분야 및 구조 등에 따라 상기 열교환판(10)의 전열유로(12) 및 포트구역(14)이 위/아래로 돌출 또는 요입되어 있으며, 상기 순환유로(20)도 역시 볼록하게 돌출 또는 오목하게 요입되도록 형성하여 상기의 전열유로(12')와 연결된다.In addition, the circulation passage 20 is formed to be convex upward or concave downward depending on the structure of the heat exchange plate 10.
