Until recently, work on compact metallic heat exchangers has sparked interest amongst heat exchanger manufacturers due to its enhanced thermal performance and energy saving benefits in comparison to conventional heat exchangers. Nevertheless, the limitations of these metallic heat exchangers which involve corrosion, weight and cost issues have created the need to develop alternative units. Much of the initial interest in the development of polymer compact heat exchangers was stimulated by their ability to handle both liquids and gases (single and two phase duties); their resistance to fouling and corrosion and their possible use in humidification and dehumidification duties. But, most importantly, the use of polymers offers substantial weight, volume, space and cost savings which give them a competitive edge over exchangers manufactured from more exotic alloys. This research focuses on the development and performance investigation of a polymer heat exchanger using thin films (PFCHE). The design incorporates the use of thin 100/-lm PEEK films, to combat the low thermal conductivity of the polymer and adopts laminar flows to avoid high pressure drops. Performance testing using industrial conditions was carried out for square and spiral PFCHE configurations, leading to the development of design correlations for various fluid systems (0.7
