Embodiment 1
[0040] Such as Figure 1a with Figure 1b Shown: a deep low temperature regenerator He-Re using helium as the heat recovery medium includes: a tube shell SC with a hot end flow hole 1 and a cold end flow hole 2, and a return tube placed in the tube shell SC The hot filler and the regenerative filler have a gas flow channel FC connecting the hot end flow hole 1 and the cold end flow hole 2, and the regenerative filler is a sealed heat exchange structure filled with helium. The shell SC is a stainless steel tube.
[0041] The sealed heat exchange structure includes: an upper end cover UC, a lower end cover DC, and several groups of heat exchange tubes T fixed between the upper end cover UC and the lower end cover DC for filling helium. The heat exchange tube T is a copper tube. Each set of heat exchange tubes T is arranged in a ring shape; multiple sets of ring heat exchange tubes T are arranged concentrically. Between two adjacent sets of heat exchange tubes T is a gas flow...
