Abstract
A cold storage unit such as a cryogenic dewar includes a tank with an opening, a storage space communicating with the opening, and a pool for liquid nitrogen positioned adjacent the storage space. The storage space receives a plurality of storage racks, each including a rack body with a rear wall and first and second sidewalls extending from the rear wall. The storage rack also includes a plurality of shelves, each shelf defined by a first lip punched from the first sidewall and a second lip punched from the second sidewall, the first and second lips being bent towards one another and spaced from one another. The shelves minimize the material and weight used in manufacturing the storage rack. Additionally, the storage rack is assembled with minimal spot welding required.
