In order to evaluate the receiver thermal properties in possible leakage situations, a theoretical analysis on different heat transfer mechanisms of residual gas in various pressures was carried out. In the meantime, a new high temperature vacuum receiver recently developed and produced by Southeast University and Sanle Electronic Group was studied by adopting special exhaust system and vacuum gauge. Thermal properties of the receiver under different annulus pressures were tested. Results showed that theoretical analysis is identical with experimental conditions, and the residual gas will increase the heat loss of receiver in both heat transfer and material characteristic ways.
