Cooling with Solid Cryogens—A Review

1966
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.

Cooling of Cryogenic Liquids by Gas Injection

1963
Subcooling of cryogenic liquids by injection of a noncondensing gas was investigated as a means of preventing excess heating of the liquid oxygen In the suction lines of the Saturn booster during prelaunch. Because of ambient heating, the liquid oxygen at the pump inlet approaches the saturation state, precluding successful bootstrapping of the H-1 ...

CRYOGENIC-SOLID COOLING TECHNIQUES

1963
Abstract : The design and development of an experimental model of a cryogenic-solid cooling system was undertaken. The current investigation of cryogenic coolant solidification techniques, as well as pressure and temperature control methods, is described. Conclusions and recommendations are made, based upon the progress of the work to date. (Author)

Cryogenically Cooled Optical Dynamic RAM

1998
Optical Dynamic RAM (ODRAM) is the first entry in an entirely new class of memory devices, offering price and performance levels that are unachievable with any other technology. ODRAM will have the capacity of magnetic hard drives but will allow up to a three order of magnitude improvement in access time.

COOLING STAGES OF CRYOGENIC SYSTEMS

2011
The formalized definition for cooling stage of low temperature system is done. Based on existing information about the known cryogenic unit cycles the possible types of cooling stages are single out. From analyses of these stages their classification by various characteristics is suggested.

METHOD OF OPERATING A CRYOGENIC COOLING DEVICE, AND A CRYOGENIC COOLING DEVICE SUITABLE FOR OPERATION BY THIS METHOD

1994
This invention concerns a method of operating a cryogenic cooling device (1) with a cylinder (4, 5) in which a piston (6, 7) reciprocates and with a gas drive (8, 9) which produces the motion of the piston. In order to reduce the vibrations which occur during operation, the invention proposes that the gas drive (8, 9) is controlled in such a way that ...
