Hydrogen Liquefier (PFHE)
Hydrogen energy series
Stainless steel plate-fin heat exchanger for liquefied hydrogen storage. The hydrogen liquefaction system of reverse Brayton cycle refrigeration consists of a helium refrigeration system and a hydrogen refrigeration system. The working medium helium in the helium refrigeration system is compressed first, and then pre-cooled by liquid nitrogen. , and then cooled by the heat exchanger step by step, and finally expanded to the low-temperature hydrogen system in the helium turboexpander. The compressed hydrogen is pre-cooled by liquid nitrogen and then cooled by cold helium in the heat exchanger to obtain liquid hydrogen
