Abstract:
A gaseous wave refrigeration apparatus comprises(a) a gaseous wave refrigeration apparatus having an adjustable nozzle, an adjustable oscillating chamber connected to said adjustable nozzle, a plurality of resonant tubes having open ends connected at apertures to said adjustable oscillating chamber penetrating thermal isolated connectors, and a flow stabilizer crossing over lower side of said adjustable oscillating chamber at the apertures of said resonant tubes, and wave impedors connected to the other ends opposite to said apertures of said plurality of resonant tubes, and a chiller embedding said resonant tubes at the other ends opposite to said apertures,(b) a resonant refrigeration means for varying flow state, using a pulsating flow of a laterally periodic jet oscillation from said adjustable nozzle in said adjustable oscillating chamber driven alternatively by each of said resonant tubes under varying flow conditions, wherein said jet oscillation under varying flow state, maintained by an adjustable pressure positive feedback loop comprising said stabilizer and said resonant tubes, couples with said adjustable oscillating chamber to create the intrinsic resonant frequency of a gaseous column in said resonant tubes under the varying flow state and governs a resonant cooling effect accompanied with said intrinsic resonant frequency of gaseous column in said resonant tubes under the adjustment of said adjustable nozzle and said adjustable oscillating chamber.
