  1. 1. Greeting Message 1 Leader Heat Exchanger | www.lhe.co.kr 는2001년7월DHT로창립후,2006년회사명을LHE로변경하면서열교환기부문에서세계속의 선두기업으로도약하고있습니다. LHE는 축적된 기술을 바탕으로 기존 판형 열교환기의 사용상 제약(고온,고압에서 사용상의 어려움)을 극복하고보다효율이좋은열교환기를개발하기위해창립이래로계속산학연공동사업을진행하는등의 구체적인 노력을 기울여 왔습니다. 이러한 지속적이고 다양한 노력들이 결실을 맺어 50,000톤급 및 25,000톤급 유압프레스라는 세계 최정상급의 설비를 확보하게 되었습니다. 그러나 LHE는 이에 안주하지 않고더더욱기술개발을위해박차를가하고있습니다. 창립초기에는 고객의 신뢰와 우수한 기술력만으로 미약한 생산설비를 극복하면서 어려운 사업들 (크리스탈라이저 반응기, Heating & Cooling)을 수주 소화해냈던 조그마한 벤처기업에서 세계 최정상급 유압프레스를 자체 기술로 설계 제작할 정도의 규모가 되기까지는 참으로 많은 시행착오와 함께 끊임없는 노력을했습니다. LHE 임직원 일동은 고객이 믿어주시는 대로 지속적인 연구개발을 통하여 앞서가는 기술과 최고의 품질로 보답하겠습니다. 처음부터 LHE를 믿어주시고 지원해주시는 많은 분들께 거듭 감사의 말씀을 전하며, 지금까지와같이앞으로도아낌없는지원과격려부탁드립니다. Since foundation of LHE, we have made tangible effort, such as Business-University Joint Research to overcome restrictions in using the existing plate heat exchangers, such as use at high temperatures and pressures, and to developmoreefficientheatexchangersbasedontheaccumulatedtechnologies.Asaresultoftheseceaselessand various efforts, we could secure the 25,000ton and 50,000 ton hydraulic presses, a world top class production facility, by our own technology. Not satisfied with current achievements, however, we still push ourselves everyday todevelopmoreadvancedtechnologiestorepayforthecustomer’ssupports. On the way from a small venture business, which won an hard-to-get order (Crystallizer Reactor and Heating & CoolingDevice)withoutanappropriateproductionfacilitybutonlywithourpuretechnologyandcustomers'trust,to a company of the current scale, which can design and develop the world class hydraulic press by its own technology, we have made ceaseless efforts with so many trials-and-errors. With those efforts and experiences, we will challenge the world top position in the industry. We are confident of our top class technologies and will bendoureffortstoproveit. Based on customers’ trust, all of our employees and managerial staff will not forget our original spirit and provide the industry’sleadingtechnologyandthebestqualityinreturnforthecustomer’ssupport. We'dliketothankallofthepeople whohavetrustedandsupportedusfromthebeginning,andaskforyourcontinuoussupportandencouragement. GreetingMessage LHE

Plate pack은 Fixed cover와 Movable cover 사이에들어가게되며Tiebolts로조여준다. The plate heat exchanger is fixed by numbers of thin and corrugated heat transfer plate, hanged between the carrying bar on the above and the guide bar on the below. These heat transfer plate provide flow channels for two kinds of fluid, and the chevrons on the heat transfer plate make the turbulent flow and play a role to support the plate against the pressure difference between the two fluids. The plate pack is to be placed between the fixed cover and the movable cover, and fixedwithtiebolts. ■원리 | Principle 전열판에는 Gasket이 부착되어 있으며 Gasket은 유로의 형성과 액이 외부로 누출되지 않도록 밀봉해 주는 역할을 하며, 열교환기 전열판의 숫자와 크기는 유량과 유체의 물리적 특성, 압력 손실 및 온도조건에 따라 결정된다. Cover는두유체의압력차이로생길수있는판이휘는것을 방지하여준다. Plate의 조립은 Plate표면(Gasket이 부착된 곳)이 Fixed cover 쪽으로 향하여 1매마다 상하 역으로 걸어주어 ''A" Plate의 표면을 흐르는 유체는 항상 ''A" Plate만을 흐르고 ''B' Plate를흐르는유체는항상''B'Plate만을흐른다. Gasket is attached to the heat transfer plate which forms flow channel and acts seal up the fluid not to leak to the outside. The number of the heat transfer plate is determined according to the amount of fluid, physical properties of fluid, the pressure drop and thermal condition. The covers prevent the plates bended from the difference of pressure. In the assembly of plate, the surface with gasket is directed to the fixed cover and each plate is hanged in opposite direction alternately. And two fluids cannot be mixed and separated by a thin plate. One fluid always flows in "A" channel and the other fluid always flow in "B" channel.

The plate heat exchanger can obtain five(5) times heat transfer efficiency compared with shell and tube heat exchanger. ­_넓은접촉면적 | Widecontactarea 열교환기 조립 시 금속접점이 약간의 면접촉이 되도록하여 점접촉으로 되어있는 타사제품에 비해 강도가 우수하며 이에따른 변형 및 응력집중을 최소화함으로서 내구성(내식성)및 수명을 크게 향상시켰다. Gasket의 단면은 유체와의 접촉 면적이 가장 적게 나오면서 탄성을 유지할 수 있는 구조로 설계 되었다. 이는 Plate 와 Gasket의내구수명에가장큰영향을미치며내압을증가시키는가장큰요인이된다. The strength of the plate is excellent, compared with other companies' products with the point contact type, as the metal contact point has the surface contact feature when the plates are assembled. And the durability and corrosion resistance are greatly improved by minimizing deformation and stress concentration. Besides, the section of the gasket is designed and manufactured to have a pressure-resistant structure thatenablestheminimumcontactareawiththefluid,andthustowithstandahighpressure. ­_LHE-ClipGasket LHE의 판형열교환기에 사용되는 GASKET은 Clip Type 또는 Snap Type의 장치에 의해 최적의 상태로 빠르고 단단하게열판에고정시킬수있으며,Gluetype과Gluefreetype을생산하여용도에맞게사용할수있다. The gasket can be fixed tightly and quickly on the heat plate in the optimum condition with the dual fixing device (snap on type), and is designed and manufactured to have the glue type and glue free typesothatitcanbeselectedaccordingtotheusage. ­_진동방지설계 | AntiVibrationDesign 연속적인 진동에도 Tie bolt/nut가 풀리지 않도록 설계를 하여 기계 수명의 증가 및 운전 중에 진동에 의한 누수를미연에방지하도록하였다.

  14. 14. COMPACT HEAT EXCHANGER Eco-HEAT14 순간온수 가열시스템은 증기를 이용하여 급탕 저탕조 없이 열교환기를 통해 급탕수를 생산하며, 센서, 콘트롤러와 콘트롤 밸브로 증기의 유량을 자동 조절하여 급탕수의 공급온도를 정밀하게 제어하는 시스템 입니다. Instantaneous water heating system using steam produces hot water through the heat exchanger without a hot water storage tank. Eco-Heat is a system that accurately controls temperature of hot water by adjusting steam flow rate with sensor, controller and control valve. INLINE PUMP 배관의 온도를 연속적으로 측정하기 위하여 순환펌프를 사용합니다. 순환 펌프는 4단계로 회전수 조절이 가능한 모터를 사용하고 무소음이며 세라믹 재질의 레이디얼 베어링을 장착하고 있습니다.단,기존급탕시스템에온수순환펌프가있는경우에는 PackagedUnit의순환펌프는생략할수있습니다.

However, if there is already a hot water circulation pump installed, circulationpumpinthePackagedUnitcanbeomitted. STEAM TRAP 세계적인 스팀 메이커인 Armstrong 트랩의 적용으로 증기의 손실이 전혀 없어 에너지 절약을 실현하며, 진공제거기의 내장으로 스팀트랩에 남아있는 진공을 완전히 제거하여 수격현상을 방지합니다. 또한, 장비와 응축수 탱크와의 거리로 인해 배압이 발생되거나, 응축수 배출이 용이하지 않을 경우 Non-electric Armstrong Condensate Recovery System(응축수 회수펌프)장치를추가할수있습니다. Because we are using steam traps made by the world's leadingproducerArmstrong,thereisnolossofthesteam andthelevelofenergypreservationishigh. Attaching vacuum remover eliminates remaining vacuum in the steam trap, then prevents water hammer phenomenon. In case of occurring back pressure from long distance between equipment and condensate water tank, or being difficult to discharge the condensate water, the nonelectric Armstrong Condensate Recovery System can beincluded(Option).

  21. 21. Leader Heat Exchanger | www.lhe.co.kr Oblong (Plate Shell) Heat Exchanger 21 특징 Characteristics ­_높은 열전달 효율 HighHeatTransferEfficiency 전열판의 주름은 낮은 Reynolds No.에서 난류를 형성하므로총괄전열계수가다관식열교환기보다4~5배인 3,000~6,000kcal/m2 h℃정도임. Corrugation of the heat transfer plates generate turbulent at a low flow velocity, and overall heat transfer coefficient is 3000 kcal/m2 h℃ ~ 6000 kcal/ m2 h℃ (4~5 times higher than that of the Shell Tube heatexchanger). ­_고내압성 | HighPressureResistance 전열판과 전열판 사이 및 Shell 구조가 Full Welded 타입이므로최고사용압력이80bar까지가능. The fully-welded structure of the heat transfer plates and the shell allows the maximum usable pressure upto80bar. ­_고내열성 | HighThermalResistance 가스켓을사용하지않는FullWelded타입이므로사용온도가 600℃까지사용가능. As it is the fully-welded type not using a gasket, the available temperature is 600℃ (up to 900℃ in maximum). ­_높은경제성 | HighEconomicalEfficiency 다관식 열교환기에 비하여 가격이 저렴하며 크기가 1/4이하로 작아지므로 설치 공간 및 무게가 감소되며, Full Welded구조이므로 주기적으로 가스켓을 교체하지 않아 유지보수비를최소화할수있다. The price is lower than that of the multi-pipe heat exchanger. Its small size (1/4 of the multi-pipe heat exchanger) reduces the required space for installation and the weight, and the fully-welded type without requiring periodical replacement of a gasket minimizes the maintenancecost. _적은오염 | LOWFOULING 전열판의 주름진 형상은 유체의 유속과 유동방향을 계속적으로 변화시켜, 순식간에 난류를 형성시킨다. 그리고 이 난류 유동은 열교환기 내부와 전열판의 표면에 이물질 부착과 스케일 형성을 막아주어 파울링 현상을 최소화시킨다. 이러한 낮은 파울링으로 인하여 셀 앤 플레이트열교환기의성능은효율적으로유지된다. Thanks to corrugation of heat transfer plate, turbulence is promptlycreatedbyacontinuouslychangingflowdirection andvelocityofthefluid.Andthisturbulencepreventsscales andadhesivematerialsfromstickingontotheheattransfer plates, which result in least fouling. Because of these low fouling tendencies,the performance of heat exchanger is usuallymaintainedingoodcondition. Type1-원형전열판(Disktypeheattransferplate) 원형 형상의 Shell과 전열판은 구조적으로 높은 내압성(진공압에서 80bar)과 내열성(600℃)의 장점을 지닌다. 또한 소형의 사이즈로 설계되므로많은산업분야에서사용하고있다. Disk type heat plate shell structure enables the operation under higher pressure(up to 80bar), and temperature(up to 600'c). Owing to its compact size it has many applications in various industries. Type2-장방형전열판(Oblongtypeheattransferplate) 장방형 전열판은 원형에 비해 긴 전열길이를 가지므로 다양한 온도조건에적용이가능하다. Compared to disk type, oblong type heat plate can be applied to a variety of temperature conditions due to its longer thermal length. D D B E E C B A C F K I J G H D D B E E C B A C F K I J G H

  24. 24. COMPACT HEAT EXCHANGER Spiral Heat Exchanger24 SpiralHeatExchanger 구조 및 원리 Structure and Principle TYPEⅠ(Liquid/Liquid) 가장 일반적인 형태이며 액체/액체, 가스/가스 및 가스/액체의 열교환에 사용된다. 고온 유체는 본체의 가운데에 있는 입구로 들어와서 중심에서 바깥쪽으로 흐르게 되며 저온 유체는 본체의 옆에 있는 입구로 유입되어 바깥에서 안쪽으로 흐르게 된다. 이러한 대향류(CounterFlow)로인해높은열교환이이루어지게되어작은온도차에서도이용할수 있다.용도에따라수직,수평어떠한형태의설치도가능하다. As the most common type, it is used for liquid-to-liquid, gas-to-gas and gas-to-liquid heat exchange. The high-temperature fluid comes in through the inlet, located in center of the main body, to flow from outside to the inside. Due to this counter flow, high-efficiency heat exchange is available and can be used for a tiny difference in temperature. Any type of installation (vertical or horizontal) is possible according to theusage. TYPEⅡ(VaporizerorCondenser) 이 형태는 특히 진공 상태나 낮은 운전 압력 조건에서의 리보일러 및 모든 유체의 증발기,응축기 및 가스의 냉각 및 가열용으로 적합하다. 기체의 유속은 큰 부피에도 적절한 수준으로 유지되며 압력손실은 최소화가 된다. 대부분 수직으로 설치하지만 용도에 따라 수평설치가가능하다. This type is suitible for reboilers,evaporators for all kind of fluid, and for cooling and heating of gas and the condenser for processing large-volume gases(at a lowpressure or vacumn) and mixture of gas and/or liquid. The flow rate of air is maintained at a proper level even for a large volume, and the pressure loss is minimized. In most cases, this type of heat exchanger is installed vertically, but horizontalinstallationisalsoavailableaccordingtotheusage. TYPEⅢ(Liquid/Vapor) 주로 액-증기계에 사용되며 가열기,냉각기,응축기 등 사용범위가 넓다. 나선과 축방향유동이 복합적으로 이루어지며 응축액과 비응축 기체나 가스가 각각 다른 출구로 배출된다. This type is mostly used for the liquid-vapor exchangers such as heaters, coolers and condensers, and has wide range of use, which generates combined flow in the spiral and axis directions. The condensed liquid and the non-condensed gas are discharged separatelytodifferentoutlets. TYPEⅣ(TopCondenser) 상부응축기(TopCondenser)는증기가유입되는입구연결부의크기를스파이럴열교환기가 연결되는기기의출구크기에맞추어제작할수있으므로별도의배관작업없이각종탑(Top ofColumn)이나반응기(ReactororKettle)상단에설치할수있다.. Top condenser can be installed on the top of column or the reactor of kettle without piping work as the connection size of the inlet for incoming vapor can be adjusted accordingtooutletsizeofthespiralheatexchanger.

As the spiral fluid passage is likely to create turbulent and the optimum flow rate is obtained by how adjusting the width of the heat transfer plates and the gap of fluid passage, the spiral heat exchanger has highheattransferringperformance ­_적은오염 | LowFouling 단일 유로는 균일하게 유체를 배분하여 오염 물질의 부착이 적고, 부착된다 하더라도 유속에 의하여 박리시키는 S e l f-C l e a n i n g이 일어나 슬러지(Sludge)를 포함한 유체에 탁월한 능력을 발휘한다. The single fluid passage of one pass structure distributes the fluid evenly to have less polluting materials adhered. Even when they are adhered, its self cleaning function peels off them by the speed of the fluid. It can be alsoappliedtosludge.­ 특징 Characteristics 스파이럴(spiral) 열교환기는 2장의 긴 전열판을 스파이럴 모양(소용돌이 형상)으로 말아 한 쌍의 나선형 유로를 형성하고 있다. 다관식 열교환기는 여러 개의 열전달관에 의하여 다수의 유로를 형성하고 있지만 스파이럴열교환기는단일의유로이므로열교환능력을저하시키는오염물질은대부분부착되지않고,유체를 완전향류로흐르게할수있기때문에열교환을효율적으로이용할수있다. The spiral heat exchanger is constructed of two long metal strips rolled around an open split center forming two concentric spiral passages, one for each fluid. While the shell tube heat exchanger depends on the several heat transfer pipes and has a number of fluid passages, the spiral heat exchanger has a single passage. As it can prevent prevent fouling which lowers heat exchange efficiency,andmakethefluidsformthecounterflowwhichenablesthehighlyefficientheatexchange. ­_온도차의유효활용 EffectiveUsageofTemperatureDifference 완전 향류로 인하여, 극히 작은 온도차까지 열교환할 수 있으므로,에너지절약에최적의효과를발휘한다.

  32. 32. LHEBloc®32 LHEBloc® COMPACT HEAT EXCHANGERON DEVELOPING LHEBloc®의 가장 큰 특징은 Plate 사이에 Gasket이 없이 Plate 상호간의 간격을 유지하며 자동 용접 하는 것으로 기계적 강도가 커서 gasketed plate heat exchanger 보다 높은 온도 및 압력의 Service을 가능하게 한다. LHEBloc®은 45°각도의 Corrugation이 있는 정사각형의 Plate를 한 장씩 용접한 열전달 부분(Heat Transfer Core)과 이 것을 보호하기 위한 Frame부분(Top/Bottom head와 4방향의 Side panel, 그리고 4개의 Column)으로 구성된다. 용접된 Plate로 구성된 Heat Transfer Core에는 Process Fluid와 Service Fluid가 용접된 각 Plate 사이로 흐르게 되고 열전달 효율을 높이기 위해 대부분 Counter Current 방식이 적용되지만 LHEBloc®은 구조상 Cross-flow 흐르며 PHE와 비슷한 수준의 높은 열전달 효율을 기대할수 있으므로 한 개의 UNIT로 Temperature Cross를 이룰 수 있으므로 최대한의 열회수를 기대 할수 있다 LHEBloc®의 구조는 매우 단순하므로, FIELD에서 쉽게 보수 및 청소 작업을 할 수 있고 내부의 Heat Transfer Core는 SIDE PANEL만 해체하면 모든 부분의 접근이 가능하다. Hot side, cold side의 유량이 다를 경우에도 Baffle를 이용하여 최적의 열교환을 하게 할 수 있다. The remarkable feature of LeaderBloc is to enable operation under higher pressure and temperature due to greater mechanicalstrengthbyweldedstructurewithoutusinginterpolaterubbergaskets. LeaderBloc® consists of plate pack(Heat Transfer Core), a group of welded square plates with 45° angle corrugation andbodyframe-toandbottomheads,foursidepanelsandfourcolumnsprotectingtheplatepack. The process and service media flow in alternately welded channels between corrugated plates. They flow in cross- flow arrangement in each pass however overall flow arrangement is counter-current in whole unit which let us expect as high heat transfer efficiency as from plate heat exchangers. Its simple structure enables easy cleaning and maintenanceinthefieldandespeciallycangettheperfectinsideaccessibilitybyunboltingsidepanels. Even in difference between hot and cold side flow rates, Optimal heat exchange shall be facilitated by using baffle whichguidethefluidtochangedirectionsinsideplatepack. 구조 및 원리 Structure and Principle

Heat transfer plate’s corrugated patterns create turbulence even at low Reynolds number and by optional multi-pass arrangement with optimal flow velocity high OHTC(Overall Heat Transfer Coefficient) can be obtained which is around 3,000 ~ 5,000kcal/㎠hr°C 4~5 times of conventional Shell Tube heat exchanger. _고내압성 | HighPressureResistance 전열판과전열판사이및FRAME구조가FullWelded타입이므로최고사용압력이35bar까지가능.

Compare to conventional shell tube heat exchanger has much lower capital cost and requires smaller installation space, and also can minimize the maintenance and service cost by eliminating periodical gasket replacementduetoitsweldedstructure. _온도의근접성 | CloseTemperatureApproach 열판의 파형패턴(Corrugated Pattern)에 의해 난류가 크게 촉진되므로 열전달계수가 매우 높으며 Temperature Approach를3℃까지도근접시킬수있습니다. High OHTC can be obtained by turbulence created from plate’s corrugated pattern, and can handle temperature approachesdownto3°C. _적은오염 | LowFouling 전열판의 주름진 형상은 유체의 유속과 유동방향을 계속적으로 변화시켜, 순식간에 난류를 형성시킨다. 그리고 이 난류 유동은열교환기내부와전열판의표면에이물질부착과스케일형성을막아주어Fouling현상을최소화시킨다. Thanks to corrugation of heat transfer plate, turbulence is promptly created by a continuously changing flow direction and velocity of the fluid. And this turbulence prevents scales and adhesive materials from sticking on to the heat transfer plates, which result in least fouling. Because of these low fouling tendencies, the performanceofheatexchangerisusuallymaintainedingoodcondition. 특징 Characteristics

Double Wave Heat Exchanger maximized the heat transfer area by adding small- scale corrugation to the existing large-scale hence smaller floor space required, and the structure of small-scale corrugation enables less fouling and greater turbulent flow for the maximum heat transfer efficiency. 이중굴곡 주름 구조의 특징은 유체의 공기접촉을 막음으로 인하여 유체내부의 오염도를 없애고 외부 비산을 막아 내외부 오염이 없는 구조로 설계가 되어있다. 고효율 전열판을 이용하여 낮은 유속에서도 난류형성을 용이하게 하여 열전달 효율을 극대화 시켰으며 유지보수가 용이하다. Double Wave Corrugation structures are specially designed to not allow internal and external contamination by preventing the internal fluid directly contacting from outer air and splashing to the outside. It also maximizes heat transfer efficiency through its super-efficient heat plate which allows to form turbulent flow easily under the low flow velocity, and maintenance is easy. • Double Wave Plate
