The upper and lower parts to be described below refer to the upper and lower parts of the heat transfer plate 30.)

그리고, 상기 후방커버(20)의 상부 가열유체 배출구(22)와 하부 가열유체 유입구(25)는 도 2를 참고하여, 급탕 재열용 열교환기(전열판(30)의 상부측)의 가열유체가 급탕 예열용 열교환기(전열판(30)의 하부측)에 전달되도록 단면상 "Y"로 형성되는 가열유체용 배관(40)이 설치되어 상호 연결되고, 상기 가열유체용 배관(40)의 끝단부 즉, 두 개가 하나로 모이는 일측은 난방용 열교환기(1)의 가열유체 배출구(전방커버(10)의 가열유체 배출구(12))와 연결되어 배출된 급탕 재열용 열교환기(2)의 가열유체가 난방용 열교환기(1)에서 배출된 가열유체와 상호 혼합되며, 상기 혼합된 가열유체는 급탕 예열용 열교환기(3)의 가열유체 유입구(후방커버(20)의 하부측)로 전달된다.In addition, the upper heating fluid outlet 22 and the lower heating fluid inlet 25 of the rear cover 20, the heating fluid of the hot water reheat heat exchanger (upper side of the heat transfer plate 30) is hot water Heating fluid pipes (40) formed in the cross-section "Y" to be delivered to the preheating heat exchanger (lower side of the heat transfer plate 30) is installed and interconnected, that is, the end of the heating fluid pipe 40, that is, One side of the two gathered together is a heating fluid outlet of the hot water reheating heat exchanger (2) connected to the heating fluid outlet (heating fluid outlet 12 of the front cover 10) of the heating heat exchanger (1) is a heat exchanger for heating Intermixed with the heating fluid discharged from (1), the mixed heating fluid is delivered to the heating fluid inlet (lower side of the rear cover 20) of the hot water preheating heat exchanger (3).

또한, 상기 후방커버(20)의 상부 열교환유체 유입구(23)와 하부 열교환유체 배출구(28)는 도 2와 도 3을 참고하여, 급탕 예열용 열교환기(3)의 열교환유체가 급탕 재열용 열교환기(2)에 전달되도록 단면상 "Y"로 형성되는 열교환유체용 배관(50)이 설치되어 상호 연결되고, 상기 열교환유체용 배관(50)의 끝단부 즉, 두 개로 분기 됐던 양끝단부가 하나로 모이는 일측은 공급처에서 이송된 급탕환수와 연결되어 배출된 급탕 예열용 열교환기(3)의 열교환유체가 급탕환수와 혼합되어 급탕 재열용 열교환기(2)의 열교환유체 유입구(후방커버(20)의 상부측)로 전달된다.In addition, the upper heat exchange fluid inlet 23 and the lower heat exchange fluid outlet 28 of the rear cover 20 refer to FIGS. 2 and 3, and the heat exchange fluid of the hot water preheating heat exchanger 3 is a heat exchanger for hot water reheating. Heat exchange fluid pipes (50) formed in the cross-section "Y" to be delivered to the machine (2) is installed and interconnected, the ends of the heat exchange fluid pipe 50, that is, both ends that are divided into two gathers into one One side is a heat exchange fluid inlet of the hot water preheating heat exchanger (3) discharged in connection with the hot water supply from the supply source is mixed with the hot water supply water exchange inlet (top of the rear cover 20) of the heat exchanger (2) Side).

상기 전열판(30)은 도 1에 도시한 바와 같이, 전방커버(10)와 후방커버(20) 사이에 다수개가 적층되어 구비되고, 상기 전방커버(10)와 후방커버(20)의 유입/배출구와 연통되도록 다수개의 이송홀(31)이 형성되어 적층시 유로가 형성된다.As illustrated in FIG. 1, a plurality of heat transfer plates 30 are stacked between the front cover 10 and the rear cover 20, and the inlet / outlet of the front cover 10 and the rear cover 20 is provided. A plurality of transfer holes 31 are formed to communicate with each other, so that a flow path is formed when stacked.

여기서, 상기 전열판(30)은 일반적인 판형 열교환기의 전열판보다 수직으로 길게 형성되어 수직 2열로 4개씩 총 8개의 이송홀(31)이 형성되고, 상기 이송홀(31)을 상부 4개와 하부 4개로 나누어 상부와 하부로 구획한다. 그래서, 상기 전열판(30)의 상부는 도 3에 도시된 난방용 열교환기(1)와 급탕 재열용 열교환기(2)를 위한 전열판의 역할을 하며, 하부는 급탕 예열용 열교환기(3)를 위한 전열판의 역할을 한다.Here, the heat transfer plate 30 is formed vertically longer than the heat transfer plate of the general plate heat exchanger is formed with a total of eight transfer holes 31 of four in two vertical rows, the transfer hole 31 to the upper four and the lower four Divided into upper and lower sections. Thus, the upper part of the heat transfer plate 30 serves as a heat transfer plate for the heat exchanger 1 for heating and the hot water reheating heat exchanger 2 shown in FIG. 3, and the lower part for the hot water preheating heat exchanger 3. It serves as a heating plate.

이때, 상기 열교환기 전열판(30)으로 이루어진 열교환기는 지역난방용 설비 유니트에 설치되는 난방용 열교환기(1)와 급탕 재열용 열교환기(2) 및 급탕 예열용 열교환기(3)가 하나로 이루어져 일체형으로 형성되는 것이며, 이렇게 전체적인 지역난방용 설비 유니트가 콤팩트해진다.At this time, the heat exchanger consisting of the heat exchanger heat transfer plate 30 is formed integrally consisting of a heating heat exchanger (1), a hot water reheating heat exchanger (2) and a hot water preheating heat exchanger (3) installed in the district heating equipment unit. In this way, the overall district heating equipment unit becomes compact.

그런데, 상기에서 전열판(30)의 상부는 난방용 열교환기(1)와 급탕 재열용 열교환기(2)를 나누어 구성하기 위해 중앙부에 이송홀(31)이 없는 전열판(30)을 설치하며, 양측의 전방커버(10)와 후방커버(20)를 통해 이송되어 온 가열유체와 열교환유체는 상기 이송홀(31)이 없는 전열판(30)에 가로 막혀 다시 양측의 전방커버(10)와 후방커버(20)로 되돌아가 배출될 수 있다.However, in the above, the upper part of the heat transfer plate 30 is provided with a heat transfer plate 30 having no transfer hole 31 in the center in order to divide and configure the heat exchanger 1 for heating and the reheat heat exchanger for hot water supply. The heating fluid and the heat exchange fluid transferred through the front cover 10 and the rear cover 20 are blocked by the heat transfer plate 30 without the transfer hole 31, and then the front cover 10 and the rear cover 20 on both sides. Can be discharged.

이렇듯, 상기 전열판(30)의 상부는 두 종류의 난방용 열교환기(1)와 급탕 재열용 열교환기(2)로 이루어지는데, 상기 전열판(30)의 하부는 한 종류의 급탕 예열용 열교환기(3)로 이루어지기 때문에 상대적으로 상부의 전열판(30) 면적이 하부의 전열면적보다 약 2배 정도 크다. 즉, 상기 전열판(30)의 하부 전열면적은 상부 전열면적의 약 1/2 크기로 형성된다.Thus, the upper portion of the heat transfer plate 30 is composed of two types of heat exchanger for heating 1 and the hot water reheating heat exchanger (2), the lower portion of the heat transfer plate 30 is one type of hot water preheating heat exchanger (3). Since the heat transfer plate 30 is relatively larger than the heat transfer area of the lower portion of about 2 times. That is, the lower heat transfer area of the heat transfer plate 30 is formed to about 1/2 the size of the upper heat transfer area.

그리고, 상기 전열판(30)의 일단면에는 고무 가스켓(32)을 각각 부착하여 상기 전열판(30)이 판형 열교환기의 원리에 부합도록 하며, 상, 하부로 구분할 수 있도록 한다. 이렇게, 상기 가스켓(32)에 의해 판형 열교환기에서 가열유체와 열교환유체의 열교환방식이 성립되고, 그로 인해 별도의 방법은 설명하지 않는다.
In addition, rubber gaskets 32 are attached to one end surface of the heat transfer plate 30 so that the heat transfer plate 30 conforms to the principle of the plate heat exchanger, and can be divided into upper and lower portions. Thus, the heat exchange method between the heating fluid and the heat exchange fluid in the plate heat exchanger is established by the gasket 32, and thus a separate method will not be described.
