Filed:

Dec 11, 2002

Appl. No.:

10/317405

Inventors:

Kuan Chen - Salt Lake City UT, US
Ampere Tseng - Tempe AZ, US

International Classification:

B01F015/00
B01F013/00

US Classification:

366/165100, 366/173100, 366/341000

Abstract:

A method and apparatus for efficiently and rapidly mixing liquids in a swirling flow micro system is disclosed. The micro mixer disclosed is a passive mixer of planar structure for simpler configuration and fabrication. The streams injected tangentially into the mixing chamber produce circular multi-lamination for effective mixing of the injected streams. The injection velocity and position can be altered by adjusting the contour and exit area of the nozzles. The planar mixer can be fabricated by the normal photolithography process in conjunction with anodic bonding. More economically the layered structures of the mixer can also be fabricated in thin plastic sheets using stamping, embossing or other thermal deformation techniques. The different layers are thermally bonded for mass production.

International Classification:

H02K 7/18
F02G 1/043

Abstract:

The present invention is characterized in that the linear reciprocating motion of a displacer piston and a rod is converted into the rotating motion of a wheel body in accordance with a thermal change, which is generated by supplying waste heat from equipment to a portion of a displacer cylinder of a Stirling engine, in that magnets mounted to the wheel body, which is linked to the cylinder rod, are rotated in a circumferential direction to form a magnetic field and to consequently generate electric power in conjunction with power line coils provided around the magnets, in that the centrifugal force generated by the rotation of the wheel body enables the cylinder rod to more powerfully perform a linear motion, and in that a bottom plate, which is coupled to the lower portion of the cylinder body, is provided with heat conduction fins to increase the heat transfer area.

International Classification:

A47L 15/42

Abstract:

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.

International Classification:

B06B 1/00

Abstract:

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.

International Classification:

B06B 1/00

Abstract:

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.
