  • 1. Leader Heat Exchanger | www.lhe.co.krGreeting Message LHE는 2001년 7월 DHT로 창립 후, 2006년 회사명을 LHE로 변경하면서 열교환기 부문에서 세계속의 선두기업으로 도약하고 있습니다. LHE는 축적된 기술을 바탕으로 기존 판형 열교환기의 사용상 제약(고온,고압에서 사용상의 어려움)을 극복하고 보다 효율이 좋은 열교환기를 개발하기 위해 창립이래로 계속 산학연 공동 사업을 진행하는 등의 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 않고 더더욱 기술개발을 위해 박차를 가하고 있습니다. 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 노력을 했습니다. LHE 임직원 일동은 고객이 믿어주시는 대로 지속적인 연구개발을 통하여 앞서가는 기술과 최고의 품질로 보답하겠습니다. 처음부터 LHE를 믿어주시고 지원해주시는 많은 분들께 거듭 감사의 말씀을 전하며, 지금까지와 같이 앞으로도 아낌없는 지원과 격려 부탁 드립니다. 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 develop more efficient heat exchangers based on the accumulated technologies. As a result of these ceaseless and 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 to develop more advanced technologies to repay for the customer’s supports. On the way from a small venture business, which won an hard-to-get order (Crystallizer Reactor and Heating & Cooling Device) without an appropriate production facility but only with our pure technology and customers 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 bend our efforts to prove it. Based on customers’ trust, all of our employees and managerial staff will not forget our original spirit and provide the industry’s leading technology and the best quality in return for the customer’s support. Wed like to thank all of the people who have trusted and supported us from the beginning, and ask for your continuous support and encouragement. Greeting Message 1

  • 6. COMPACT HEAT EXCHANGERPlate and Frame Heat Exchanger특징Characteristics _최고의 열교환 효율 | High efficiency 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 열교환계수를 얻을 수 있다. (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. _넓은 접촉면적 | Wide contact area Dead Zone 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 Others Gasket의 내구 수명에 가장 큰 영향을 미치며 내압을 증가시키는 가장 큰 요인이 된다. 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 Ours the durability and corrosion resistance are greatly improved by minimizing deformation and stress Contact Area Comparison concentration. Besides, the section of the gasket is designed and manufactured to have a pressure-resistant structure that enables the minimum contact area with the fluid, and thus to withstand a high pressure. Improved Wave _LHE-Clip Gasket LHE의 판형열교환기에 사용되는 GASKET은 Clip Type 또는 Snap Type의 장치에 의해 최적의 상태로 빠르고 단단하게 열판에 고정시킬 수 있으며, Glue type과 Glue free type을 생산하여 용도에 맞게 사용할 수 있다. 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 type so that it can be selected according to the usage. _진동 방지 설계 | Anti Vibration Design 연속적인 진동에도 Tie bolt/nut가 풀리지 않도록 설계를 하여 기계 수명의 증가 및 운전 중에 진동에 의한 누수를 미연에 방지하도록 하였다. Designed to prevent loosening the tightening bolts and nuts during continuing operation which secure to prolong the equipments operation lifetime and prevent leakages.6 Plate and Frame Heat Exchanger

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 mechanical strength by welded structure without using interpolate rubber gaskets. LeaderBloc® consists of plate pack(Heat Transfer Core), a group of welded square plates with 45° angle corrugation and body frame-to and bottom heads, four side panels and four columns protecting the plate pack. 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 maintenance in the field and especially can get the perfect inside accessibility by unbolting side panels. Even in difference between hot and cold side flow rates, Optimal heat exchange shall be facilitated by using baffle which guide the fluid to change directions inside plate pack.32 LHEBloc®

High OHTC can be obtained by turbulence created from plate’s corrugated pattern, and can handle temperature approaches down to 3°C. _적은 오염 | Low Fouling 전열판의 주름진 형상은 유체의 유속과 유동방향을 계속적으로 변화시켜, 순식간에 난류를 형성시킨다. 그리고 이 난류 유동은 열교환기 내부와 전열판의 표면에 이물질 부착과 스케일 형성을 막아주어 Fouling 현상을 최소화시킨다. 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 performance of heat exchanger is usually maintained in good condition. LHEBloc® 33

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 cooling load of the gear and bearing oil, and reducing the maintenance and repair items required..
