Resonately Coupled Alpha-Stirling Cooler

Summary

 

Technology Description

 

Disclosed is a resonantly coupled alpha-Stirling cooler that has hot and cold variable-volume chambers, a regenerator, and a driver for maintaining reciprocating gas displacement between the chambers. Only the hot side of the cooler is driven; the cold side responds passively by resonant coupling. The phase difference between volume oscillations in the hot and cold variable-volume chambers are altered by adjusting the driving frequency.

 

 Applications

 

Can be made small enough to cool electronic components or provide mobile, temporary refrigeration effects.
