Abstract:
A plate heat exchanger for accommodating two circulating heat exchange mediums, comprising:a plurality of heat transfer plates mounted in parallel relationship to each other defining alternating fluid channels comprising first and second fluid channels, the first fluid channel for containing a first heat exchange medium, the second fluid channel for containing a second heat exchange medium; and an electrode plate located in each first fluid channel and positioned generally parallel to and spaced from the heat transfer plates, the electrode plate including outer electrode surfaces on each side thereof to produce an electric field, wherein the outer electrode surfaces of each electrode plate include surface irregularities having sharp points, and wherein the electric field is intensified at the sharp points of the surface irregularities to pull the first heat exchange medium toward the surface irregularities to increase the heat transfer rate between the first heat exchange medium and the second heat exchange medium.
