ACOUSTOPHORESIS DEVICE WITH DUAL ACOUSTOPHORETIC CHAMBER

摘要

An acoustophoresis device includes an acoustic chamber (155, 157) with a piezoelectric element (160) located within its volume. The piezoelectric element vibrates and generates acoustic standing waves from both sides, so that particles can be separated from fluid passing through the acoustic chamber. This permits the element to be cooled more efficiently, reducing transient heat loads in the fluid traveling through the device.
