Abstract
A rectangular double walled cryogenic freezer has a vacuum space filled with alternating layers of flexible insulating material and a reflective material. A support structure is also positioned in the vacuum space. The support structure is open-celled and provides structural support for the freezer walls to prevent wall deformation when a vacuum is drawn. The support structure may be open-cell rigid foam or a support grid sandwiched between two layers of rigid insulation material.
