摘要

Metallic and graphitic open-cell foams are being used or proposed as extended surfaces (fins) in heat sinks for electronic cooling and compact heat exchangers for aircraft applications. Three parameters must be known to calculate the heat transfer performance of a foam-fin: the product h_mA_c~* as a function of flow-rate (the convective conductance per unit volume), the product k_sA_k~* (the effective conductive conductance as a fin), and R_(bond) (the effective thermal resistance between the foam and the surface to which it is attached). This paper describes a new test method, which, in conjunction with an older well established type of test, allows all three parameters to be measured using one specimen.
