In the counter-flow heat exchanger core, airflows are passed by each other along parallel aluminum plates in counter-flow direction. This allows to achieve the higher temperature efficiency than using crossflow heat exchanger core. Two neighbor aluminum foils form a Cross flow plate heat exchanger high quality recuperatorCross flow plate heat exchanger high quality recuperator. ALUMINIUM CROSSFLOW PLATE HEAT EXCHANGER. In a crossflow heat exchanger heat is transferred directly from the outlet air to the make up air through the separating walls of the heat exchanger. Both sensible and latent heat may be transferred. Latent heat when moisture in the outlet air condensates on the recuperator.
They can also be configured for counter-flow or cross-flow operation. In these exchangers the parallel plates are formed with either staggered or inline dimple patterns to reduce the potential for particulate fouling. The Dimple Plate Heat Exchanger can recover energy from an industrial exhaust with temperatures up to 1,200° F (650° C). HEAT EXCHANGERS - ThermopediaPlate and Frame Heat Exchangers consist of two rectangular end members which hold together a number of embossed rectangular plates with holes on the corner for the fluids to pass through. Each of the plates is separated by a gasket which seals the plates and arranges the flow of fluids between the plates, see Figure 9.
