Thermoelectrics in cryogenic cooling

2020 IEEE 22nd Electronics Packaging Technology Conference (EPTC), 2020
A use case for thermoelectric coolers (TEC) in cryogenic cooling application is presented where the heat load is small and the required temperature difference between the hot and cold sides ( $\Delta \mathrm{T}$ ) is very high. The application shown here is the cooling of image sensors used in telescopes.

Machining Ti–6Al–4V alloy with cryogenic compressed air cooling

International Journal of Machine Tools and Manufacture, 2010
A new cooling approach with cryogenic compressed air has been developed in order to cool the cutting tool edge during turning of Ti–6Al–4V alloy. The cutting forces, chip morphology and chip temperature were measured and compared with those measured ...

System-Level Impingement Cooling with Cryogens

Journal of Thermophysics and Heat Transfer, 2020
System-level impingement cooling with cryogens has potential thermal applications in size-constrained, weight-constrained, and power-constrained or low-atmosphere environments by utilizing a phase change for enhanced heat transfer at cryogenic temperatures. In this work, an experiment capable of measuring the heat and mass flow of liquid nitrogen jets

Cryogenic cooling of monochromators

Review of Scientific Instruments, 1992
In this paper, we report on the design and x-ray diffraction properties of cryocooled silicon single crystals exposed to the following wiggler beams: power density: 150 W/mm2, total power: 75 W and power density: 0.5 W/mm2, total power: 100 W. First, thermomechanical and engineering aspects of low-temperature crystal cooling are discussed, leading to ...
