摘要： Disclosed herein is a high-efficiency kilohertz-range acoustic wave generator using a pulsed thermal radiation beam and nanoparticles. A vibration (pulse) generating means having a suspension structure is provided behind a light interrupter. The suspension structure is configured such that nanoparticles are suspended in a solution so that when the nanoparticles are thermally expanded by pulse beams directly applied to the nanoparticles and are thermally contracted, the solution vibrates (generates matter waves and pressure waves). Thereby, loss of pulse beams can be minimized, and energy having a relatively large wavelength can be easily obtained. Therefore, the efficiency and productivity in generating acoustic waves can be maximized.

摘要： Disclosed herein is a high-efficiency kilohertz-range acoustic wave generator using a pulsed thermal radiation beam and a nanostructure. A nanorod unit having a high thermal expansion coefficient is provided behind a light interrupter so that the efficiency of generating acoustic waves can be enhanced. A pulse beam generated from the light interrupter is directly radiated onto the nanorod unit having a nanorod bundle structure with a nanorod-opposite-end support. Thermal deformation of the nanorod unit attributable to thermal expansion and contraction is repeated. In this way, the amplitude of sound waves can be increased, and relatively high decibel sound can thus be generated.

摘要： Disclosed herein is a dishwasher using oscillatory flow generated from thermoacoustic effect. The dishwasher is configured such that thermoacoustic waves having high amplitude are generated from solar energy rather than electric energy, wherein the thermoacoustic waves make oscillating waves be directly transmitted to an air column and a water column formed in a closed end of a dishwashing pipeline. In this way, high-quality energy can be directly applied to washing water, whereby energy loss can be minimized, and the washing efficiency can be markedly increased.
