Piezoelectric Polymer Heat Exchanger.
Abstract
Disclosed is apparatus for providing for increased heat transfer efficiency of a heat exchanger by separating sheet fabricated from conductive channels by means of a flexible sheet fabricated from a piezoelectric polymer. An electrode pattern of predetermined configuration is applied to one or both sides of the pipiezoelectric sheet and an electrical signal applied thereto in order to set the sheet into a flexual resonance condition whereupon a standing wave pattern is established to not only break up the boundary layer of fluid which adheres to each side of the sheet, but also minimizing the thickness of the laminar sub-layer.
