Abstract

A plate type heat exchanger for liquid is provided to prevent liquid boiling due to the difference of heat capacities as two kinds of the liquid exchange heat with each other, thereby improving the lifespan and the safety of a system. A plate type heat exchanger for liquid includes path spaces for fluid to be heated and heating fluid. In order to prevent the boiling of the fluid to be heated while a system is stopped operating since the temperature of heating fluid is much higher than that of the fluid to be heated, the path spaces(A1-An) for the fluid to be heated are formed larger than those(B1-Bn) for the heating fluid so as to provide a heat capacity(the boiling point) of the fluid to be heated equally to or larger than that of the heating fluid.

Description

액체용 판형열교환기{Plate-type heat exchager for liquid}Plate-type heat exchanger for liquid

본 발명은 2종의 액체를 서로 열교환하는 경우 열용량의 차로 인하여 끓는 점이 낮은 액체의 보일링 발생을 방지할 수 있는 액체용 판형열교환기에 관한 것이다.The present invention relates to a plate heat exchanger for a liquid that can prevent the boiling of the low boiling liquid due to the difference in heat capacity when the two liquids heat exchange with each other.

열기기, 냉동기기 등 관련 장치의 대다수가 열원으로부터 간접적으로 서로 다른 매체에 공급하거나 반대로 열을 흡수하기 위해 열교환기를 사용하고 있다.The majority of related devices, such as hot air and freezers, use heat exchangers to indirectly feed different media from heat sources or vice versa.

이러한 열교환기는 일반적으로 서로 열교환이 이루어지는 매체의 종류에 따라, 액체/기체 열교환기와, 기체/기체 열교환기와, 액체/액체 열교환기로 나누어진다.Such a heat exchanger is generally divided into a liquid / gas heat exchanger, a gas / gas heat exchanger, and a liquid / liquid heat exchanger, depending on the type of medium in which heat exchange is performed.

이 중에서, 액체와 액체 간의 열교환은 일반적으로 열전도성이 좋은 재료로 이루어진 전열관이 2개의 유로로 구성하고, 상기 2개의 유로가 전열면을 사이에 두고 서로 맞닿은 상태로 하여 서로 다른 액체가 각기 유로를 지나면서 상대측에 열전달이 이루어지도록 한다. 이때, 열교환기의 부피를 작게 하면서 열접촉면적을 크 게 하기 위해서, 판형열교환기가 사용되고 있다.Among them, the heat exchange between the liquid and the liquid is generally composed of two flow paths of heat transfer tubes made of a material having good thermal conductivity, and the two flow paths are in contact with each other with the heat transfer surface interposed therebetween. Pass the heat to the other side. At this time, in order to increase the thermal contact area while reducing the volume of the heat exchanger, a plate heat exchanger is used.

대한민국공개공보 제1999-0079555호에서는 다수 개의 전열판(1)과 전열판(1)의 둘레를 밀폐시키기 위한 패킹(2)과 전열판(1) 사이에 형성되는 가열유체공간(3)과 피가열유체공간(4)을 각기 연결하는 연결관(5)을 구비하고, 다수의 열매공간(3)을 연결하는 최상단의 연결관(5)에는 열매가 입수되도록 하고, 다수의 피가열유체공간(4)을 연결하는 하단의 연결관(5)에는 피가열유체가 입수되는 판형 열교환기를 제시하였다.In Korean Laid-Open Patent Publication No. 1999-0079555, a heating fluid space (3) and a heated fluid space formed between a packing (2) and a heat transfer plate (1) for sealing a plurality of heat transfer plates (1) and the perimeter of the heat transfer plate (1). Each of the connection pipes (4) are provided with a connecting pipe (5), the uppermost connecting pipe (5) for connecting a plurality of fruit spaces (3) to obtain the fruit, and the plurality of heated fluid space (4) The connecting pipe 5 at the bottom of the connecting plate presented a plate heat exchanger in which the heated fluid is obtained.

그러나, 대한민국공개공보 제1999-0079555호는 피가열 유체가 단계적으로 가열될 수 있도록 하여 가열유체와 피가열 유체간의 온도차가 적어지도록 할 수 있으나, 가열유체공간과 피가열유체공간이 동일하기 때문에 2개의 매체가 열용량이 크게 상이한 경우, 피가열유체가 끓는점이 낮고 열용량이 작은 경우에는 쉽게 기화되는 문제가 여전히 남아 있다.However, Korean Laid-Open Patent Publication No. 1999-0079555 allows the heated fluid to be heated in stages so that the temperature difference between the heated fluid and the heated fluid can be reduced, but since the heated fluid space and the heated fluid space are the same, 2 When the two mediums differ greatly in heat capacity, the problem of evaporating easily remains when the heating fluid is low in boiling point and low in heat capacity.

이러한 경우에 장치가 정지되어 유동이 없을 때, 두유체가 서로 충분한 시간을 가지고 열교환이 이루어져 평형상태를 이룬 결과 피가열유체의 비등점보다 높은 온도를 유지한다면 판형열교환기 내부에서는 액체가 기화되고 이에 따른 급격한 부피팽창으로 인하여, 열교환기에 무리한 압력이 지속적으로 가해지게 되고, 이러한 무리한 압력 증가는 열교환기를 폭발시키거나 변형을 일으키고, 기체가 관로 상에 존재함으로서 액체펌프가 기능을 상실하는 등 많은 문제점을 일으킨다. In this case, when the device is stopped and there is no flow, the two fluids have sufficient time to exchange heat with each other to achieve an equilibrium state, and as a result, if the temperature is maintained above the boiling point of the fluid to be heated, the liquid vaporizes inside the plate heat exchanger, and accordingly the rapid Due to the volume expansion, excessive pressure is continuously applied to the heat exchanger, and this excessive pressure increase causes many problems such as explosion or deformation of the heat exchanger, liquid pump loss of function due to the presence of gas in the pipeline, and the like.

본 발명의 목적은 2종의 액체를 서로 열교환하는 경우 열용량 차로 인한 보일링 발생을 방지할 수 있는 액체용 판형열교환기를 제공함에 있다.An object of the present invention is to provide a plate heat exchanger for liquid that can prevent the occurrence of boiling due to the difference in heat capacity when the two liquids are heat exchanged with each other.

본 발명은 복수의 층간공간을 가지도록 복수의 플레이트가 적층되어 2개의 유로공간이 형성되어서 가열유체와 피가열유체가 열교환되는 통상의 액체용 판형열교환기에 있어서, 가열유체의 온도가 피가열 유체의 비등온도 보다 훨씬 높은 경우 장치가 정지하였을 때, 피가열유체의 유로공간은 피가열유체가 흐르는 유로공간 내의 피가열유체에 대한 비등에 상당하는 열용량을 가열유체가 흐르는 유로공간 내의 가열유체에 대한 열용량보다 같거나 크도록 형성한 것을 특징으로 한다.The present invention relates to a plate-type heat exchanger for a liquid, in which a plurality of plates are stacked to have a plurality of interlayer spaces, and two flow path spaces are formed so that the heating fluid and the heated fluid are heat-exchanged. When the apparatus is stopped when the temperature is much higher than the boiling temperature, the flow volume of the heated fluid is equivalent to the boiling capacity of the heated fluid in the flow passage space in which the heated fluid flows, and the heat capacity of the heated fluid in the flow passage space in which the heating fluid flows. It is characterized by being formed to be the same or larger.

바람직하게, 상기 유로공간은 판형열교환기를 구성하는 판의 크기는 동일하지만 판간의 간격이 서로 상이한 것을 특징으로 한다.Preferably, the flow path space is the same size of the plate constituting the plate heat exchanger, characterized in that the spacing between the plates are different from each other.

바람직하게, 상기 피가열유체가 흐르는 유로공간은 장치가 정지되어 유동이 일어나지 않을 때, 두유체가 서로 충분한 시간을 가지고 열교환이 이루어져 평형상태를 이룬 뒤에도 피가열유체의 비등점보다 낮은 온도를 유지하도록 상기 가열유체 유로공간과 피가열유체가 흐르는 유로공간의 크기를 서로 다르게 형성시킨 것을 특징으로 한다.Preferably, the flow path space in which the heated fluid flows is heated to maintain a temperature lower than the boiling point of the heated fluid after equilibrium due to heat exchange between the two fluids when the device is stopped and no flow occurs. The fluid flow path space and the flow path space through which the heated fluid flows are differently formed.

본 발명의 액체용 판형열교환기는 2종의 액체를 서로 열교환하는 경우 열용량의 차로 인한 보일링 발생을 방지할 수 있다.Plate heat exchanger for the liquid of the present invention can prevent the occurrence of boiling due to the difference in heat capacity when the two liquids heat exchange with each other.

또한, 비열의 차가 큰 액체간의 열교환에도 쉽게 적용시켜 장치의 수명이나 안전성, 펌프의 장해 등 고장의 원인을 제거할 수 있다.In addition, it can be easily applied to heat exchange between liquids having a large difference in specific heat, thereby eliminating the causes of failures such as the life and safety of the device and the failure of the pump.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 2는 본 발명에 따른 액체용 판형열교환기의 개략도이다.2 is a schematic view of a plate heat exchanger for liquids according to the present invention.

도시된 바와 같이, 본 발명의 액체용 판형열교환기는 복수개의 플레이트인 A1, B1, A2, B2 ..., AN, BN 등이 순차적으로 적층된 2N개의 공간을 갖도록 형성된다. 플레이트 'A'의 내부 공간에는 가열유체가 흐르며, 플레이트 'B'의 내부 공간에는 피가열유체가 흐른다고 하자. 이때, 판형열교환기는 복수개의 플레이트가 A1, B1, A2, B2 ..., AN인 2N-1개의 공간을 가지도록 형성될 수도 있다.As shown, the liquid plate heat exchanger of the present invention is formed to have 2N spaces in which a plurality of plates A1, B1, A2, B2 ..., AN, BN, etc. are sequentially stacked. Suppose that a heating fluid flows into the inner space of the plate 'A' and a heated fluid flows into the inner space of the plate 'B'. At this time, the plate heat exchanger may be formed such that the plurality of plates have 2N-1 spaces A1, B1, A2, B2 ..., AN.

복수의 플레이트에는 적층되는 방향과 수직한 방향으로 1쌍의 유입구(11,21)와 유출구(12,22)가 설치된다. A1, A2 ..., AN의 플레이트에는 가열유체가 유입되는 제1유입구(11)와 가열유체가 배출되는 제1유출구(12)가 각각 형성되고, B1, B2 ..., BN의 플레이트에는 1쌍의 피가열유체가 유입되는 제2유입구(21)와 피가열유체가 배출되는 제2유출구(22)가 각각 형성된다.The plurality of plates are provided with a pair of inlets 11 and 21 and outlets 12 and 22 in a direction perpendicular to the stacking direction. In the plate of A1, A2 ..., AN, the first inlet 11 through which the heating fluid is introduced and the first outlet 12 through which the heating fluid is discharged are formed, respectively, and the plates of B1, B2 ..., BN A second inlet 21 through which a pair of heated fluid flows in and a second outlet 22 through which the heated fluid flows out are formed.

실시예에서는 제1,2유입구(11,21)와 제1,2유출구(12,22)가 모두 상방으로 개방되도록 형성되어 있으나, 이들 유입구 및 유출구의 개방 방향에 대해서 제한은 없다. 다만, 액체의 경우에는 액체의 유출구(12,22)가 상측에 설치되는 것이 액체용 열교환기의 내부를 충진할 수 있어서 바람직하다.In the embodiment, all of the first and second inlets 11 and 21 and the first and second outlets 12 and 22 are upwardly open, but there is no limitation on the opening directions of these inlets and outlets. In the case of a liquid, however, it is preferable that the outlets 12 and 22 of the liquid are provided at the upper side to fill the inside of the liquid heat exchanger.

따라서, 피가열유체가 흐르는 짝수의 유로공간에 위치하는 부분에 제1폐쇄부(13)가 형성되어 가열유체가 유입되는 것을 방지하고, 또한, 가열유체가 흐르는 홀수의 유로공간에 위치하는 부분에 제2폐쇄부(23)가 형성되어 피가열유체가 유입되는 것을 방지한다.Therefore, the first closed portion 13 is formed in the portion of the even flow path space in which the heated fluid flows, thereby preventing the heating fluid from flowing into the portion of the odd flow path space in which the heating fluid flows. The second closing part 23 is formed to prevent the heated fluid from flowing in.

이러한 제1,2폐쇄부(13,23)의 반복적인 배치를 통해 가열유체는 제1유입구(11)를 통해 홀수의 유로공간에만 유입되고, 제1유출구(12)를 통해 동일 홀수의 유로공간에서 배출된다. 또한, 피가열유체는 제2유입구(21)를 통해 짝수의 유로공간에 유입되고, 제2유출구(22)를 통해 동일 짝수의 유로공간으로부터 배출된다.Through the repeated arrangement of the first and second closure parts 13 and 23, the heating fluid flows into only the odd flow path space through the first inlet 11 and the same odd flow path space through the first outlet 12. Ejected from In addition, the heated fluid is introduced into the even flow path space through the second inlet 21 and discharged from the same even flow path space through the second outlet 22.

한편, 열교환되는 가열유체와 피가열유체의 비열과 끓는 점이 상이한 경우에는 홀수 및 짝수의 유로공간의 크기를 다르게 설정한다. 즉, 유로공간을 구성하는 판의 크기는 동일하므로 판간의 간격(l1,l2)을 조절하여 홀수의 유로공간(A1, A2 ..., AN) 및 짝수의 유로공간(B1, B2 ..., BN)이 서로 차이가 있도록 설계할 수 있다.On the other hand, when the specific heat and the boiling point of the heating fluid to be heated and the fluid to be heated are different, the sizes of the odd and even flow path spaces are set differently. That is, since the size of the plate constituting the flow path space is the same, the distance between the plates (l1, l2) is adjusted to the odd flow path space (A1, A2 ..., AN) and even flow path space (B1, B2 ... , BN) can be designed to be different from each other.

따라서, 홀수의 유로공간에서 흐르는 가열유체의 열용량과 피가열유체의 비등점에 해당하는 열용량을 동일하게 하거나 또는 피가열유체의 비등점에 해당하는 열용량을 가열유체의 열용량보다 크게 함으로써 피가열유체의 끓는 현상을 방지할 수 있다. 예를 들면, 가열유체가 오일인 경우 오일의 열용량은 Qo=Mo·Cpo·ΔT이고, 피가열유체가 물인 경우 물의 비등점에 해당하는 열용량은 Qw=Mw·Cpw·(TB-Ti)이므로 Qo≤Qw이면 물의 끓음 현상을 방지할 수 있다.Therefore, the boiling phenomenon of the heated fluid by making the heat capacity of the heated fluid flowing in the odd flow path space and the boiling point of the heated fluid the same or making the heat capacity corresponding to the boiling point of the heated fluid larger than the heat capacity of the heated fluid. Can be prevented. For example, when the heating fluid is oil, the heat capacity of the oil is Qo = Mo · Cpo · ΔT, and when the heating fluid is water, the heat capacity corresponding to the boiling point of water is Qw = Mw · Cpw · (T B -T i ). If Qo ≦ Qw, water boiling can be prevented.

결국, 가열유체와 피가열유체 중 가열유체의 온도와 끓는점이 높고 피가열유체보다 열용량이 상대적으로 큰 경우에는 갑작스럽게 장치가 정지하여 열교환기의 유동이 멈추는 경우에도 피가열유체가 흐르는 유로공간의 부피를 가열유체가 흐르는 유로공간보다 크게 하면 시간이 경과하여 안정상태에 이르러서도 피가열유체의 온도가 끓는점 이상으로 유지되었던 종래의 문제점을 예방할 수 있다.As a result, if the temperature and boiling point of the heating fluid and the heating fluid are higher than the heating fluid and the heating capacity is relatively higher than the heating fluid, the device suddenly stops and the flow of the heated fluid flows even if the flow of the heat exchanger stops. When the volume is larger than the flow path space through which the heating fluid flows, the conventional problem of maintaining the temperature of the heated fluid above the boiling point even when reaching a stable state over time can be prevented.
