摘要： Examples of a pressure wave generator configured to generate high energy pressure waves in a medium are disclosed. The pressure wave generator can include a movable piston with a guide through which a piston control rod can move or slide. The pressure wave generator can include a transducer coupled to a medium. During an impact of the piston on the transducer, the control rod can slide in the guide, which can reduce stress on the rod. The pressure wave generator can include a damper to decelerate the control rod, independently of the piston. Impact of the piston on the transducer transfers a portion of the piston's kinetic energy into the medium thereby generating pressure waves in the medium. A piston driving system may be used to provide precise and controlled launching or movement of the piston. Examples of methods of operating the pressure wave generator are disclosed.

摘要： Heat exchangers can be utilised in thermo-acoustic engines to facilitate through acoustic oscillations electrical power generation via linear alternators and/or cooling effects. Provision of a heat exchanger arrangement 31 which can be associated with a traditional open flame stove utilised in third world countries would be advantageous. However, such heat exchanger arrangements must be lightweight and robust to withstand operational use. By creating a heat exchanger arrangement formed from plates having apertures which develop a folded conduit to act as a resonance tube of appropriate length it is possible to more easily accommodate thermo-acoustic electrical power generation and cooling effects in a traditional stove configuration.

摘要： A thermoacoustic cooling system for cooling an object such as a microelectronic chip. Heat produced by the object is transferred to a thermoacoustic engine. The thermoacoustic engine may include a resonator defining a chamber. A stack may be positioned in the chamber with one side of the stack adjacent to the heat source, and the opposite side of the stack adjacent to air in the chamber having a relatively cooler temperature. One or more orifices may be formed in the resonator such that the acoustic power generated by the thermoacoustic engine creates a synthetic jet to circulate air and move the air away from the object being cooled. Thus, the heat produced by the object is used to power the thermoacoustic engine to thereby remove heat from the object. The thermoacoustic engine may use no moving parts and may require no external power source other than the object being cooled.
