Such a plate heat exchanger can achieve a miniaturization of the power generation apparatus by increasing the heat exchange area and the heat exchange time, and furthermore, there is an advantage of increasing the heat exchange efficiency.
상기 증발기를 판형 열교환기로 사용함으로써, 통상적인 증발기 대비 20 내지 50%로 부피를 줄일 수 있고, 부피가 작게 하면서도 3 열효율을 3 내지 5배 높일 수 있다.By using the evaporator as a plate heat exchanger, it is possible to reduce the volume by 20 to 50% compared to the conventional evaporator, and to increase the thermal efficiency 3 to 5 times while reducing the volume.
한편, 판형 열교환기는 열효율을 높으나 쉘-튜브(shell&tub) 타입의 열교환기 중 캐틀형 타일의 쉘-튜브 열교환기 같이 열교환기 윗부분에 증발된 유체를 저장하는 역할을 하지 못해 외부의 맥동치는 열에 영향을 받게 되는데, 이러한 작동유체의 불안정한 유동을 유동화안정파이프(600)에 의해 해결할 수 있다.On the other hand, the plate heat exchanger has high thermal efficiency but does not play a role of storing the evaporated fluid in the upper part of the heat exchanger like the shell-tube heat exchanger of the cattle tile among the shell & tub type heat exchangers. The unstable flow of the working fluid can be solved by the fluidization stabilized pipe 600.
상기 유동안정화파이프(600)는 소형화하면서 그 체적을 충분히 확보할 수 있도록 길이가 길게 형성되는 것이 바람직하다. 그러므로 상기 유동안정화파이프(600)는 그 길이가 상기 열교환판의 적층된 두께보다 상대적으로 더 길게 형성되도록 하는 것이 바람직하다.The oil purification pipe 600 is preferably formed to have a long length so as to sufficiently secure the volume while miniaturizing. Therefore, the oil purification pipe 600 is preferably such that its length is formed relatively longer than the laminated thickness of the heat exchange plate.
도 4는 도 3에서 유동화안정화파이프의 상세도이다.4 is a detailed view of a fluidization stabilized pipe in FIG. 3.
더 자세하게, 상기 유동안정화파이프(600)의 직경(D)은 상기 주배관의 직경(d)의 2 내지 5배로 하는데, 그 이유는 유동안정화파이프(600)의 직경은 최소 주배관의 직경대비 2배 이상이 되어야 맥동현상이 방지되어 유동안정화를 유지할 수 있으며, 유동안정화파이프(600)의 직경(D)은 주배관의 직경(d) 대비 최대 5배 이하로 하여 발전장치에서 유동안정화파이프 설치를 컴팩트화할 수 있다. In more detail, the diameter (D) of the oil purification pipe (600) is 2 to 5 times the diameter (d) of the main pipe, because the diameter of the oil purification pipe (600) is more than twice the diameter of the minimum main pipe. The pulsation phenomenon can be prevented to maintain purification during the oil, and the diameter (D) of the oil purification pipe 600 can be made up to 5 times or less than the diameter (d) of the main pipe to compact the installation of the oil purification pipe in the power generator. have.
또한, 상기 유동안정화파이프의 길이(L)는 상기 열교환판의 적층된 두께(t)의 2배 내지 5배인 것으로 실시하였다. 그 이유는 유동안정화파이프(600)의 길이(L)는 열교환판의 적층된 두께(t)의 2배 이상되어야 유동안정화를 유지할 수 있으며, 유동안정화파이프(600)의 길이(L)가 열교환판의 적층된 두께(t)의 5배 이하로 하여 발전장치의 유동안정화파이프 설치를 위한 부피를 컴팩트화할 수 있다.In addition, the length L of the oil purification pipe was 2 to 5 times the laminated thickness t of the heat exchanger plate. The reason is that the length L of the oil purification pipe 600 must be at least two times the stacked thickness t of the heat exchange plate to maintain the oil purification, and the length L of the oil purification pipe 600 is the heat exchange plate. It is possible to reduce the volume for installing the purification pipes for the oil generation period of the power generation apparatus by making it 5 times or less of the stacked thickness t of.
상기 유동안정화파이프(600)는 상세하게 그 구성을 다음과 같이 나눌 수 있다. 상기 응축기(300) 단부에 연결되는 플랜지(620)와, 상기 플랜지(620) 단부에 결합되며 상기 주배관의 직경보다 큰 직경을 가진 파이프(640)와, 상기 파이프(640)의 단부에 연장되어 직경이 점차 축소되어 상기 주배관과 연결되는 연결관(660)으로 구성되는 것을 특징으로 한다.The oil purification pipe 600 may be divided in detail as follows. A flange 620 connected to an end of the condenser 300, a pipe 640 coupled to an end of the flange 620 and having a diameter larger than the diameter of the main pipe, and extended to an end of the pipe 640. It is gradually reduced is characterized in that consisting of a connecting pipe 660 connected to the main pipe.
여기서, 상기 유동안정화파이프(600)는 상기 플랜지(620)와 상기 파이프(640) 및 연결관(660)이 일체로 된 모듈형상으로 제작할 수 있다.Here, the oil purification pipe 600 may be manufactured in a modular form in which the flange 620, the pipe 640, and the connection pipe 660 are integrated.
즉, 상기 유동안정화파이프(600)는, 일측은 상기 응축기(300)와 플랜지 연결되고 타측은 주배관(500)과 용접결합되게 한다. 그리고, 유동안정화파이프와 응축기 사이에 결합을 위해서 상기 응축기의 단부에는 상기 유동안정화파이프의 플랜지 사이에 금속 가스켓이 설치되게 하여 밀착하고 볼트로 체결하여 리크(leak)를 최소화한다.That is, the oil purification pipe 600, one side is flanged to the condenser 300 and the other side is to be welded to the main pipe 500. Further, in order to couple between the oil purification pipe and the condenser, a metal gasket is installed between the flanges of the oil purification pipe at the end of the oil condenser so that the metal gasket is in close contact and fastened with bolts to minimize leakage.
