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

■구조 | Structure
판형 열교환기는 상부의 Carrying bar와 하부의 Guide
bar사이에 장착된 얇고 주름진 여러 장의 전열판으로 구성
되어 있다. 이 전열판은 두 종류의 유체가 통과하는 유로를
형성해주며,전열판에형성된주름은유체의흐름을난류로
만들어 주고 두 유체간의 압력차에 대해 판을 지지해 주는
역할을 한다. 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.

특징
Characteristics _최고의열교환효율 | Highefficiency
전열판(Plate)은 최대의 열전달 효과를 얻기 위해 주름(Corrugated, 파형)모양의 패턴을 형성하였으며, 유체의
흐름을 난류(Turbulence)로 만들기 위해 유로를 경사지게 배열하고, 또한 이들의 흐름방향을 대향류
(Countercurrent Flow)로 하였으며 열교환기내에 체류하는 유체의 체적을 작게하고, 정체되는 곳(Dead
Space)이 없으므로 최고의 열교환 효율을 발휘한다. 다관식(Shell & Tube)열교환기에 비해 5배 이상의
열교환계수를얻을수있다.(K값:3,000~6,500kcal/㎡h℃,Water/water)
The heat transfer plate forms corrugation to maximize the heat transfer efficiency and chevrons to
create turbulence flow also designed to make countercurrent flow which enables to diminish the
quantity of fluid remaining in the heat exchanger and eliminate the dead-zone. 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

The gasket can be fixed tightly and quickly on the heat plate in the optimum condition with the dual

Eventhebiggestmodelalsocanbeassembledordisassembledby1or2persons.
As it is designed to have a dual fixing method of the insert-typed plate and insert-typed gasket, there is no
sliding on the plates. It prevents sliding and an assembling failure even when a non-skilled novice

_온도의근접성 | TemperatureApproach
열판의 파형패턴(Corrugated Pattern)에 의해 난류가 크게 촉진되므로 열전달 계수가 매우 높으며 Temperature

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.

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

Top condenser can be installed on the top of column or the reactor of kettle without

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

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

_높은열전달효율 | HighHeatTransferEfficiency
Plate Coil은 Service Side와 Process Side에 높은 열전달계수를 얻을 수 있다. High Serviced Side(Inside Plate
Coil)은 큰 난류유동과 Dead Point가 발생하지 않고, 내측 체적에 비해 큰 표면적으로 인해 큰 경막 전열계수를
얻을 수 있다. High Process Side(Outside Plate Coil)은 부드러운 곡률에 의한 Fouling에 대한 저항으로 인해
경막전열계수를얻을수있어PipeCoil에비하여전열효율이월등하다.(약2배)
The high serviced side inside the plate coil does not creates big turbulent flow and dead points, and a
high film coefficient of heat transfer can be obtained due to the large surface area, compared to the
internalvolume.

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

_높은열전달효율 | HighHetatTransferEfficiency
전열판의주름은낮은ReynoldsNo.에서난류를형성하고pass선택에의하여최적의유속이얻어지므로높은
총괄전열계수을얻을수있다.
다관식열교환기보다4~5배인3,000~5,000kcal/㎠hr℃정도임.
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

_높은경제성 | HighEconomicalEfficiency
다관식 열교환기에 비하여 가격이 저렴하며 크기가 1/4이하로 작아지므로 설치 공간 및 무게가 감소되며, Full Welded
구조이므로주기적으로가스켓을교체하지않아유지보수비를최소화할수있다.
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.

기존의 주름형상에 미세한 주름을 삽입함으로써 단위 부피당 전열면적을 극대화하여
적은 설치면적이 요구되며 미세 주름의 구조로 인해 오염(fouling) 현상을 억제하고
난류형성을 용이하도록 하여 열전달 효율을 극대화한 제품이다.
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.

통상 블로워에는 베어링과 기어 등을 보호하기 위해 오일을 사용하며, 이를 연속적으로 냉각하기 위한 냉각수가 필요합니다.
이로서 냉각탑이 별도의 대형장비로 외부에 설치되는데 여름철에는 냉각탑내의 병원균, 겨울철에는 관로 동결로 인한 파열 등의
문제가자주발생합니다.
Green Turbo는 기어 및 베어링용 오일의 냉각열량을 최소화 시켜, 냉각수를 사용하지 않고 공기로 냉각하는 시스템을 채택하여,
USER의유지보수 ITEM을줄였습니다.
The blower generally uses oil to protect the bearings and gears, and it requires cooling water to cool the unit
continuously. This requires a cooling tower, large and separate equipment installed on the outside. This is prone to
causing problems, such as germ problems inside the tower in the summer and the freezing and bursting of pipes in the
winter. Green Turbo has applied an air-cooling system to replace this hassling system, minimizing the process of the
coolingloadofthegearandbearingoil,andreducingthemaintenanceandrepairitemsrequired..
