Cooling with Solid Cryogens—A Review
The current Interest in the use of cryogens in the solid phase is focused upon their application as heat sinks for cooling electronic components, particularly infrared detectors, in aircraft and spacecraft [1–5]. The solid-cryogen cooler stores a solid mass of cryogen in a vented dewar system. The item to be cooled is usually mounted on a metal pedestal which is thermally communicated to the solid. The ullage space about the stored solid is evacuated to maintain the cryogen in Its solid state. Heat entering from the refrigerated object and the surroundings causes the cryogen to sublime and the resulting vapor is vented.
