Fluidic devices, including constant-rotation double diodes and constant-rotation double vortex tubes, are disclosed with which to construct pulse tube refrigerators having diode loops, constant-rotation double diodes, constant-rotation double vortex tubes, and asymmetrical diode stacks. Present orifice pulse tube refrigerators use an orifice connected at the warm end of the pulse tube to a reservoir. The orifice and reservoir serve to control flows at the warm end of the pulse tube so that they are not in phase with flows at the cold end. Present heat ex...
[ What is claimed is:] [1.] A pulse tube refrigerator apparatus including:a pulse tube having a warm end and a cold end;a reservoir connected in fluid communication with said warm end of said pulse tube;at least one vortex chamber having an interior wall, said vortex chamber connected between said warm end of said pulse tube and said reservoir; andmeans for injecting fluid tangentially into said vortex chamber, causing said fluid entering said vortex chamber to circulate around said interior wall of said vortex chamber.
