Claims

[Scope of utility model registration request]

A regenerator type refrigerator that uses high-pressure helium gas as a cooling medium is characterized by a structure in which the mesh of wire mesh regenerator material stacked inside the regenerator becomes finer as the temperature decreases. Cold storage refrigerator.
