Cryogenic cooler with enhanced compression

Abstract

Cryogenic cooler with enhanced compression. The cryogenic cooler generates cold by performing a thermodynamic cycle with a cryogenic working fluid. The cryogenic cooler comprises a fluidic circuit (30) having one or more first chambers (32) and a second chamber (34), each first chamber (32) being fluidically connected to the second chamber (34). Each first chamber (32) includes an elastically deformable wall (38). The cryogenic cooler (10) includes one or more actuation devices (50) arranged to deform the elastically deformable wall (38) of the first chamber(s) (32) to vary the volume of the first chamber(s) (32).
