Possibilities are considered for using the thermal imaging method for analyzing the operation of insulationrnsystems of cryogenic equipment. Requirements are given for thermal images and features of their use inrndiagnosing cryogenic equipment.rnIt is shown that thermal imaging makes it possible to record the location of a local increase in heat influxrnfor articles with such high quality thermal protection as cryogenic vessels with layered vacuum insulationrnunder high vacuum conditions in the thermal insulation cavity.rnThermograms are presented for the faceplate of cryogenic vessels with participation of increased heatrninflux. The possibility is analyzed of calculating excess heat influx on the basis of thermograms.
