ALEX is the trade name of a brazed aluminum heat exchanger developed independently by Kobe Steel in 1963 for use as the regenerator in air separation plants. Kobe Steel is one of the leading manufacturers of brazed aluminum heat exchangers and is the top user of ALEX. We also own the air separation plants technology within our group.
Plate-fin heat exchanger High-efficiency Aluminum Plate-fin Heat Exchanger:Hangyang has continuously developed advanced high-efficiency fins and studied the brazing process technology. In October 2016, Hangyang successfully developed a high-pressure heat exchanger of 12.8MPa, which broke the foreign enterprises 10.0MPa The technology monopoly of the above high-pressure heat exchanger
Brazed Aluminum Plate-Fin Heat Exchangers Reduce Costs Mar 01, 2000 · The heat transfer fin design enhances the stream flow characteristics and increases the amount of heat transferred. A brazed aluminum plate-fin heat exchanger is considered versatile because it can handle the flows and duties of many different types of fluids such as gas-to-gas, gas-to-liquid, two-phase or any combination thereof, with each stream optimized and balanced thermally and
to the cryogenic separation of air in the 1950s, there are now many thousands of aluminium plate fin heat exchangers (PFHE) in operation throughout the world. Also referred to as brazed aluminium heat exchangers (BAHXs), their use has been extended so much so that BAHXs are mission critical across a wide variety of cryogenic fractionation
Coil Wound Heat Exchanger - kyairsepProduct Description. Compared with the traditional shell-and-tube heat exchanger, the Coil wound heat exchanger is more superior for its high pressure bearing capacity, wide applicable temperature, strong corrosion resistance and multi-stream heat exchange. At present, the maximum size of the products can be up to 3,500×25,000mm and the maximum design pressure is up to 20Mpa, supporting the heat exchange
Jun 08, 2018 · Heat exchanger Heat transfer Modeling Optimization ABSTRACT The cryogenic industry has experienced remarkable expansion in recent years. Cryogenic technologies are commonly used for industrial processes, such as air separation and natural gas liquefaction. Another recently proposed and tested cryogenic application is Liquid Air Energy Storage
DESIGN OF COMPACT PLATE FIN HEAT EXCHANGERPlate fin heat exchangers can be made in a variety of materials. Aluminium is preferred in cryogenic and aerospace applications because of its low density, high thermal conductivity and high strength at low temperature. The maximum design pressure for brazed aluminium plate fin
Fives brazed aluminium plate-fin heat exchangers (BAHX) are a critical component in the helium liquefaction, purification, separation, refrigeration, and recovery processes. Along with our high-quality Cryomec ® VSMP and Cryomec ® DELTA N pumps, they are an effective and reliable choice for plants specializing in the production of both helium and HyCO (hydrogen and carbon monoxide).
SAFE USE OF BRAZED ALUMINUM HEAT EXCHANGERS gaseous product from the separation column, warm the GOX to ambient temperature and then raise its pressure with a GOX compressor. Brazed aluminum heat exchangers (BAHXs) are normally used as oxygen product vaporizers. Their use creates substantial contact between high pressure oxygen (both as LOX and GOX) and aluminum mate-rial.
Aluminum plate-fin heat exchanger is a kind of high efficiency, compact and cryogenic heat exchanging equipment, with characteristics of complicated design theory, high fin molding precision and brazed to be a whole piece at one time, especially applicable to the cases of multi-stream or state changes during heat transfer. Most brazed aluminum plate-fin heat exchangers have been installed
