Applictions of Thermoacoustics
Application 1: Thermoacoustic Cryocooler
Our cryocooler use independently developed air-floatation linear oscillation engines which, by opposed positioning, reduce vibration to nearly undetectable level. This feature makes our cryocoolers especially suitable for vibration-level demanding environments.
We also successfully get rid of moving parts in cold-finger: this not only reduces vibration, but also improves the cold-finger’s impact resistance by avoiding internal dysfunction caused by lateral acceleration.
Furthermore, we developed dedicated SPWM controllers for each model of our cryocoolers. They allow users to control refrigeration accurately even in extremely demanding applications. All these features-low vibration, cold-finger impact resistance, great life performance and accurate controlling-make our cryocoolers ideal solutions in cryogenic platforms.
Application 2: Thermoacoustic Engine
Our thermoacoustic engines convert thermal energy into mechanical energy through the “forward (positive)” of thermoacoustic effect. Thermoacoustic engine is a platform technology that can be used in a wide range of applications involving thermal-mechanical engine conversion. Thermoacoustic engine, as an external combustion engine, is more environmental friendly than traditional internal combustion engine by consuming solar energy, biomass and industrial residual heat instead of polluting fossil energy sources.
Our thermoacoustic engine achieves thermal cycling primarily through gas rather than mechanical processes. As a result, its internal structure, similar to that of our cryocoolers, is largely free of moving parts, making it more reliable and cost-efficient than traditional engines.
Application 3: Thermoacoustic Heat Pump
Our thermoacoustic heat pump works through the “backward (negative) process” of thermoacoustic effect. Using linear oscillation engine, our heat pump first converts electric energy into pressure wave (acoustic energy), and then creates difference-in-temperature on Thermoacoustic units (i.e. regions where thermoacoustic effect takes place). Heat pump is achieved through simultaneous processes at both the cold-end and the hot-end of a thermoacoustic unit: at the cold-end, heat exchange is carried out by interacting with ambient temperature by a cooling radiator; at the hot-end, where heat pump effect occurs, temperature increases under acoustic influences.
Thermoacoustic Heat Pump is more efficient than traditional electric heating. In terms of civil and industrial high-temperature acquiring, our thermoacoustic Heat Pump is expected to be 2~3 times as efficient as mainstream electric-heating devices.
Thermoacoustic Heat Pump is especially powerful in high difference-in-temperature environments: it outperforms similar products in applications that operate in high difference-in-temperature, e.g. water-heating and electric automobile heat-pumping.
