Abstract: A rectangular double walled cryogenic freezer (10,110) has a vacuum space (16,116) filled with alternating layers of flexible insulating material (20,120) and a reflective material (18,118). A support structure (22,122) is also positioned in the vacuum space (16,116). The support structure (22,122) is open-celled and provides structural support for the freezer walls to prevent wall deformation when a vacuum is drawn. The support structure (22,122) may be open-cell rigid foam (122) or a support grid (22) sandwiched between two layers of rigid insulation material (26a,26b).

Abstract translation: 矩形双壁低温冷冻机（10,110）具有填充有柔性绝缘材料（20,120）和反射材料（18,118）的交替层的真空空间（16,116）。 支撑结构（22,122）也位于真空空间（16,116）中。 支撑结构（22,122）是开放式的，并且为冷冻壁提供结构支撑以防止在抽真空时产生壁变形。 支撑结构（22,122）可以是开放式刚性泡沫（122）或夹在两层刚性绝缘材料（26a，26b）之间的支撑格栅（22）。
