Experimental investigation of heat transfer and flow characteristics in finned copper foam heat sinks subjected to jet impingement cooling

The rapid development of electronic devices has made it necessary to develop novel and innovative thermal management solutions. This paper experimentally investigated the heat transfer and flow characteristics of three new finned copper foam heat sinks subjected to the impingement cooling by rectangular slot jet and axial fan. The effects of heat sink height (H, 15, 30, 45, 60 mm), the pore density of the inserted copper foam (PPI, pore per inch...
