ABSTRACT:
A cryogenic cooler system which allows continuous and uninterrupted cooling ithin the system with minimized moving parts. A compressor assembly is included with more than one compressor so that at any one time, one of the compressors is active so as to provide a working gas pressure modulated by piston action. An expander assembly includes an expander associated with each compressor where working gas pressure expansion from the active compressor is expanded within. A conduit line couples each compressor to each expander for working gas connection between each compressor and respective expander. Heat pipe is coupled at one end to each expander for the transfer a coolant fluid to a cooling plate which includes a temperature sensor. Thermal switches within each of the heat pipes control coolant fluid flow to allow the activation of another heat pipe and associated compressor when failure of the currently operating compressor occurs.
