AbstractSunpower proposes to design the regenerator-displacer component of a novel duplex free-piston Stirling micro-refrigerator for cold electronics in aerospace applications. The micro-refrigerator, to be located inside microelectronics packages, exploits the material properties, mechanical designs, tiny dimensions, and batch fabrication processes of silicon micromachining technology. If feasible, the micro-refrigerator will enable electronic devices bonded directly to its silicon cold plate, or fabricated within it, to operate at temperatures from 250K down to 60K or less, depending upon the application-specific design. Thermodynamic simulations predict a nominal 1 W of heat lifting capacity from 225K by micro-refrigerators
