Heat transfer and pressure drop are analyzed across the two, novel plate-fin heat sinks (with perforations and slots). The experimental data validates the conjugate heat transfer CFD model for the air-cooled heat sink. The results from the CFD model show that novel plate-fin heat sinks tend to have a higher heat transfer coefficient than the plane fins without slots and perforations. Also, pressure drop of the novel plate-fin heat sinks is lower than the plane plate-fin heat sink, so less fan power is required for novel heat sinks. For a range of Re number 13,049 to 52195, on average novel plate-fin heat sink-1 (NPFHS-1) and novel plate-fin heat sink-2 (NPFHS-2) have 42.8 and 35.9 higher Nu number than that of the plane plate-fin heat sink (PPFHS). An additional advantage of the reduction in mass of heat sink is achieved because of slots and perforations. © 2020 Elsevier Ltd date: 2021 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85092536062&doi=10.1016%2fj.applthermaleng.2020.115949&partnerID=40&md5=7676c5c7bcc42b5cc42cd759bd8f6a9f id_number: 10.1016/j.applthermaleng.2020.115949 full_text_status: none publication: Applied Thermal Engineering volume: 182 refereed: TRUE issn: 13594311 citation: Tariq, A. and Altaf, K. and Ahmad, S.W. and Hussain, G. and Ratlamwala, T.A.H.
