Estimating the term…
Disclosed are a cold storage material and a cold storage type cryogenic refrigerator using same. The cold storage material is tin alloy particles, the content of tin in the tin alloy particle is not less than 40% and not more than 99%, and the cold storage material at least includes one component of bismuth, antimony, silver and gold. The cold storage type cryogenic refrigerator includes a cold storage device, and the cold storage material filled in the cold storage device is tin alloy particles, is lead-free, lowly toxic, easy in spherization and extremely accessible and has a relatively good thermal performance, has properties comparable to those of lead, and has a relatively good heat exchange performance when being used in a cold storage type refrigerator.
A cold storage type cryogenic refrigerator using a cold storage material, wherein the cold storage material is tin alloy particles, and the content of tin in the tin alloy particle is not less than 40% and not more than 99%, the cold storage type cryogenic refrigerator comprising a cold storage device, wherein the cold storage material filled in the cold storage device is tin alloy particles, wherein the cold storage device comprises a first-stage pushing piston (11) and/or a second-stage pushing piston (12), and a first-stage cold storage material (11c) filled in the first-stage pushing piston (11) and/or a second-stage cold storage material (12c) filled in the second-stage pushing piston (12) uses tin alloy particles, and
