Heat exchanger e.g. foil heat exchanger, for transferring heat between fluids, has thin, flexible plastic containing foils utilized as heat transferring surfaces between flow channels of fluids, where surfaces are designed from foils layers

摘要

The exchanger has a thin, flexible plastic containing foils (3) utilized as heat transferring surfaces between flow channels of fluids (1). Fibers for increasing mechanical stability and/or minerals and/or ceramic are provided in the utilized foils against different plastics, metal and/or carbon black. The heat transferring surfaces are designed from multiple foils layers. Auxiliary fixtures are designed as grid nets (4) and provided in the flow channels for equalizing of fluid flows and increasing the flow turbulence of the fluids. The flow channels have a spiral structure between the foils.
