The analytical solutions have an important role in applications of the heat transfer. In this work are presented theoretical and experimental aspects about the heat transport by radiation with applications in cryogenic systems. The objective of this paper is to show the importance of the thermal shields for reducing the influence of the radiation and also is to show the effect of the vacuum pressure on the thermal loading in cryogenic applications. The numerical and experimental investigations are presented for four different thermal shields. These thermal shields were tested on the Sumitomo SRDK Series cryocooler system.
