The comparison between both heat exchangers is done based on a well-defined Performance Evaluation Criterion (PEC), taking heat transfer and pressure drop in account. Furthermore, as the studied heat exchangers are so-called ‘low-capacity’ units, a non-uniform temperature field downstream the heat exchanger is induced. Therefore an area-mean temperature reading has been developed, with the aid of an infra red camera. Finally, the contribution of the contact resistance to the overall thermal resistance of these pressed-fit heat exchangers is investigated.9 pagesPDFenUniversity of PretoriaAirside resistanceAluminium foamLouvered finsPerformance Evaluation CriterionPECInfra red cameraContact resistanceThermal resistanceLow velocity applicationsPresentation
