Thermo-Hydraulic Performance of Heat Sinks With Microchannel Embedded With Pin-fins

Anas Alkhazaleh, Mohamed Younes El-Saghir Selim, Fadi Alnaimat, Bobby Mathew
Proc. ASME. HT2021, ASME 2021 Heat Transfer Summer Conference, V001T06A002, June 16–18, 2021
Publisher: American Society of Mechanical Engineers
Paper No: HT2021-62804
https://doi.org/10.1115/HT2021-62804
... Abstract In this work, an investigation of the heat sink performance employing sinusoidal microchannels embedded with pin fins was conducted. The effect of the sine wave frequency, the pin fins’ diameter, and the hydraulic diameter of the microchannel are studied. The results are quantified...

... and the stator. Impingement of cooling jet is an effective way of cooling the disc and countering the ingress of the hot gases. Present study focusses on investigating the effect of introducing pin-fins over the rotating disc on the heat transfer. The jet Reynolds number has been varied from 5000 to 18000...

Computational Fluid Dynamics Based Investigation of the Performance of Hybrid Heat Sinks

Anas Alkhazaleh, Mohamed Younes El-Saghir Selim, Fadi Alnaimat, Bobby Mathew
Proc. ASME. HT2021, ASME 2021 Heat Transfer Summer Conference, V001T05A003, June 16–18, 2021
Publisher: American Society of Mechanical Engineers
Paper No: HT2021-63099
https://doi.org/10.1115/HT2021-63099
... Abstract This article discusses the mathematical modeling of a straight microchannel heat sink, embedded with pin-fins, for purposes of liquid cooling of microelectronic chips. The influence of three different geometrical parameters, pin fins’ diameter, pitch, and hydraulic diameter...
