ABSTRACT:
The Mechanical Freezer of this invention closely approaches an ideal freezer cycle composed of constant temperature compression, expansion, and constant volume heating (load transfer) by using power piston106that power input shaft50moves up and down and displacers104and105that are moved by cam108. When power piston106moving up and additional displacer105moving down come together, fluid is forced through additional heat sink41where it is cooled as it is compressed. When additional displacer105and primary displacer104come together, fluid is forced through primary heat sink40where it is cooled as it is compressed. After compression, the cooled fluid is expanded by power piston106along with displacers104and105moving down. When displacers104and105then move up, fluid is forced through load30and load30is cooled.
