Heat Transfer Performance of a Novel Multi-Baffle-Type Heat Sink [PDF]

open access: yesEntropy, 2018
A new type of multi-baffle-type heat sink is proposed in this paper. The heat-transfer coefficient and pressure drop penalty of the employed six heat sink models are numerically investigated under five different inlet velocities. It is shown that Model 6 (M6) has excellent heat transfer performance as its heat-transfer coefficient reaches a value of ...
