Our Focus Issues

01
Innovative R&D
Brazed Plate Heat Exchangers

Featuring wave patterns stamped on 304 or 316 stainless steel materials, Kaori's brazed plate heat exchangers are made through multi-point brazing of stainless steel with copper or nickel in a vacuum furnace, thereby allowing them to operate under extreme pressure in a very small chassis while making them especially suitable for refrigeration and air conditioning systems. Meanwhile, the wave patterns stack on top of each other to form conduits that create a turbulent flow of the coolant even at low flow speeds. This enables the heat exchangers to achieve high thermal conduction efficiency in a small heat transfer area. In systems that require high efficiency, the use of brazed plate heat exchangers may further increase the coefficient of performance (COP) and reduce the overall space needed to install the modules, which in turns lessens the need for fluorinated greenhouse gases (F-GHG) and is a more efficient and environmentfriendly design.

Industry Applications
  • Air conditioning
  • Semiconductors and electronics
  • Refrigeration
  • Energy and utilities
  • Machinery
  • Transportation
  • Medical equipment
  • Data centers
Technological Highlights in Environmental Sustainability
  • B series heat exchangers reduce coolant requirements and increase the COP of heat pumps and chillers.
  • Double-wall plate heat exchangers have been developed for use as heat pumps in European and American homes. Using a patented plate design, a special drainage is created within the heat exchanger so that any internal leakage of fluid on one side can be drained directly without mixing with fluid on the other side, which may damage important components or pose harm to the user. The product also offers multiple advantages such as low coolant requirement, high COP, and suitability for next-generation environment-friendly coolants and natural coolants.
  • Kaori's 3-in-1 plate heat exchanger for high capacity refrigerant air dryer has completed technological and pressure resistance certification, and has the potential to save energy and reduce coolant requirements in high capacity units.
Gasket Plate Heat Exchangers

Offers better heat conduction in a smaller size compared to spiral type or shell and tube type heat exchangers. With proper design, gasket plate heat exchangers can be more efficient at transferring heat and easier to clean, maintain, disassemble, and install while retaining the potential for capacity expansion.

Industry Applications
  • Petrochemical plants
  • Oil refineries
  • Steel
  • Power generation
  • Freight
  • Semiconductors
  • Metal processing
  • Food
  • Refrigeration
Technological Highlights in Environmental Sustainability
  • Energy efficiency and conservation:
    The special pattern design enables a high level of turbulent flow even at low flow speeds, therefore delivering a number of advantages including efficient heat transfer, reusability, and a longer lifespan of at least 10 years.
  • Heat recycling:
    Data centers, for example, may use a combination of immersion liquid cooling and gasket plate heat exchangers to recycle heat and increase overall energy efficiency by more than 40%.
Critical SOFC Components
High-efficiency Fuel Cell Recuperators

Heat-resistant nickel-base superalloys are assembled using Kaori's proprietary brazing technology in conjunction with advanced TIG welding to allow heat transfer under high temperatures. The material achieves a thermal cycle efficiency of 60%. This demonstration of exceptional brazing and TIG welding techniques has gained recognition from green manufacturers worldwide and made Kaori a long-term strategic partner.

Industry Applications

A solid oxide fuel cell (SOFC) is a form of distributed energy system which involves generating and supplying power directly to local users based on their requirements. Kaori's solutions offer a high degree of versatility that make them suitable for medium- and small-size energy conversion systems of various purposes. Ships, for example, may install fuel cell power systems to replace diesel power.

Technological Highlights in Environmental Sustainability
  • Advantages such as high performance, stability, low emissions, zero pollution, waterless, and long lifespan have been validated through commercial operation by reputable customers for more than 10 years.
  • Thermal reactors for high capacity SOFCs increase power generation efficiency to 65% from the previous generation.
  • Thermal reactors have been developed for hydrogen generation and energy storage.
  • Application in vessels helps the shipping industry achieve energy and carbon reduction goals.
Reformed Methanol/Hydrogen PSA System

The hydrogen generator takes in a methanol solution and applies a process called pressure swing absorption (PSA) to purify and generate high-purity hydrogen (99.999%). It is widely used in industrial processes that make use of the gases generated, such as hydrogen reduction furnaces, heat treatment furnaces, semiconductors, and optoelectronics.

  • 30-4.5 m3/hour
  • Generates hydrogen at low pressure (<5 kg/cm2)  with rigorous safety protection
  • Uses methanol (<59%) as the raw material; the hydrogen produced can be used immediately and does not require a hydrogen storage tank
  • Replaces pressurized hydrogen canisters; equipment investments can be recovered in as little as six months
Industry Applications
  • Supports hydrogen-based production procedures or by-product hydrogen: for example, hydrogen reduction furnaces, heat treatment furnaces, semiconductors, optoelectronics, powder metallurgy, metal wires, and steel industries.
  • Organic solvent waste fluids of the electronics industry (semiconductors, circuitry, LCD panel, etc.) can be preprocessed and cracked at high temperature to separate hydrogen for power or heat.
Technological Highlights in Environmental Sustainability
  • Ammonia cracking and hydro power
    Clean energy research involving the use of ammonia as hydrogen fuel carrier has gained popularity around the world in recent years due to the ease of storage, ease of transportation, and better economic viability of ammonia compared to hydrogen.
Immersion Liquid Cooling System

Kaori's Thermal Energy Business has come up with an immersion liquid cooling system to cool the increasing number of cloud data center servers worldwide. When used in data center servers, immersion liquid cooling system is able to quickly disseminate heat buildup from high performance computing, and when used in conjunction with Kaori's plate heat exchanger, power usage effectiveness (PUE) can be kept below 1.1.

Industry Applications
  • Cloud services/5G communication
  • Edge computing
  • Data centers
  • Semiconductor EDA
  • Artificial intelligence
  • Blockchain
  • Cryptocurrency
    (mining)
  • Electric vehicle battery cooling
Technological Highlights in Environmental Sustainability

Power usage effectiveness (PUE) is an internationally accepted measurement for the power efficiency of data centers. PUE is calculated by dividing the “total data center power draw” by the “total IT equipment power draw”. A low PUE indicates that the data center requires less power for cooling, which suggests lower power consumption and greater environmental friendliness.

  • China's first data center with 5A green rating uses single-phase immersion cooling technology with insulated coolant to achieve high-efficiency cooling without the need for fans, air conditioners, or chillers. The solution reduces power used in cooling by 70% and lowers the PUE to 1.09.
