|Title:||Heat spreading of liquid jet impingement cooling of cold plate heat sink with different fin shapes|
Fins (heat exchange)
Liquid jet impingement
Liquid mass flow rate
|Abstract:||This paper presents the heat spreading of the cold plate heat sink with different fin shapes (rectangular, circular, conical) using the jet impingement technique impinging on the heating surface. The parametric monitoring mainly focused on the liquid mass flow rate, inlet coolant temperature, and fin shapes are investigated. The results showed that the fin shapes of the heat sink influencing its total thermal resistance but small decrement in heat spreading resistance. By fixing other parameters and a jet-plate spacing to jet diameter ratios H/D = 0.8 is considered, it is shown that the circular fin has a higher thermal performance by lowering thermal resistance of the heatsink for 12%, and 25% compared with the rectangular and the conical fin, respectively. More importantly, the lower coolant temperature is reduced heat spreading, results in total thermal resistance are developed. The numerical was carried out, and the clear temperature distribution phenomena with different fin shapes are obtained, which contribute to the heat spreading, spreading resistance, and thermal resistance to the cold plate heat sink for cooling in electronic applications. © 2020 The Authors.|
