A Review on Highly Compact Perforated Plate Heat Exchanger for Cryogenic Applications
Keywords:Cryogenic, Highly compact, Highly effective, Hydrogen, Matrix heat exchanger, Perforated plate, Porosity
This paper describes a variety of fundamental research of cryogenic perforated plate heat exchanger which works at
temperature 123K (-150℃) or below it, also it is most critical component used for separation, purification, liquefaction, refrigeration
systems, working w ith different cryogenic gases like helium, hydrogen, neon, nitrogen, oxygen, air etc. Its primary function is “to converse
cold” i.e. allow the removal of energy from the compressed incoming gas by transferring energy to the low -pressure cold stream. So, it is
alw ays desirable to prevent “heat inleaks” to the system, as it is more difficult to remove energy from the low -temperature regions. Also
apart from having a high effectiveness, cryogenic heat exchangers also need to be very compact, i.e. they must accommodate a large
amount of surface area in a small volume. This helps in controlling heat exchange with the surroundings by reducing exposed surface area.
Perforated plate matrix heat exchanger (MHE) covers advantages of high effectiveness and high degree of compactness together in one
unit used for cryogenic applications. This paper deals with the brief review of research articles in chronological development of perforated
plate matrix heat exchanger.
