Optimum thermal design of interrupted microchannel heat sink with rectangular ribs in the transverse microchambers

Numerical study of laminar flow and heat transfer in microchannel heat sink with offset ribs on sidewalls

“…They found that the heat sink could significantly reduce the pressure drop and enhance heat transfer, due to the shortened effective flow length. Chai et al [7] studied the pressure drop and heat transfer characteristics of interrupted microchannel heat sinks with rectangular ribs in transverse chambers. Based on performance evaluation criteria, they obtained the optimal dimensions and locations of the rectangular ribs.…”

Optimum design of triangular shaped micro mixer in micro channel heat sink

“…The results implied that the shield shaped groove microchannel possessed high heat exchange performance with the increment of Nusselt number at about 1.3 times of the plain surface structure. Chai et al [14] studied the pressure drop and heat transfer characteristics of the interrupted microchannel heat sink with rectangular ribs in the transverse micro chambers and analyzed the effects of dimension and position parameters of rectangular rib on these characteristics.…”

Parametric study on thermal and hydraulic characteristics of laminar flow in microchannel heat sink with fan-shaped ribs on sidewalls – Part 2: Pressure drop

“…They found that the redeveloping flow was repeated for all of the independent zones and the repeated thermal developing flow greatly enhanced the overall heat transfer. Subsequently, Chai et al [4] introduced the staggered rectangular ribs into the transverse microchambers and studied the heat transfer characteristics in such heat sinks. The geometry parameters (e.g.…”
