Thermally efficient internal support structures in cryogenic applications: A comprehensive review

Abstract

Internal support structures in cryogenic systems play a vital role in maintaining mechanical stability while limiting conductive heat transfer into the cold regions of the system. Balancing these two requirements presents a significant design challenge, especially in systems operating at very low temperatures where minimizing heat ingress is critical for performance and energy efficiency. A fundamental aspect of meeting this challenge lies in material selection. Materials such as stainless steel and fibre-reinforced composites are widely used due to their high strength, stable mechanical behaviour at cryogenic temperatures, and relatively low thermal conductivity. These properties offer a hi..
