A Review on Highly Compact Perforated Plate Heat Exchanger for Cryogenic Applications

Abstract

Abstract-This paper describes a variety of fundamental research of cryogenic perforated plate heat exchanger which works at temperature 123K (-150℃) or below it, al so it i s most critical component used for separation, puri fication, liquefaction, refrigeration systems, working w ith di fferent cryogeni c 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 i s al w ays desirable to prevent "heat inleaks" to the system, as it i s more di fficult to remove energy from the low -temperature regions. Al so apart from having a high effectiveness, cryogeni c 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 arti cles in chronological development of perforated plate matrix heat exchanger.
