Numerical Predictions of the Flow and Thermal Performance of Water-Cooled Single-Layer and Double-Layer Wavy Microchannel Heat Sinks

Parametric study on thermal performance of microchannel heat sinks with internal vertical Y-shaped bifurcations

“…Yet the double-layered microchannel heat sinks showed a substantial reduction in pressure drop and the temperature rise compared to the single-layered microchannel heat sinks. Xie et al [28] also numerically validated the performance of water-cooled single-layered and double-layered microchannels. Xie et al [29] performed a comparative study of the flow and thermal performance of double-layered wavy microchannel heat sinks and they also confirmed that the double-layered wavy microchannel heat sinks outperform conventional rectangular straight mircochannels.…”

Characteristics of entropy generation and heat transfer in double-layered micro heat sinks with complex structure

“…The above literature review showed that the authors all considered as DL-MCHSs having better thermal performance than [4][5][6][7][9][10][11][12]24,25] all pointed out the pressure drop of DL-MCHSs were lower that of SL-MCHSs, while the Work of Wu et al [8] gave the opposite conclusion.…”

“…Sharma et al [24] considered the performance of DL-MCHS with trapezoidal structure and compared it with DL-MCHS with simple structure, which showed superiorly in the aspects of thermal resistance and temperature variations. A DL-MCHS with wavy structure was proposed by Xie et al [25], which showed that wavy micro heat sink had better thermal performance over the traditional micro heat sinks.…”

Numerical analysis and parametric study of multilayered microchannel heat sinks

“…The subscripts s and l denote solid rib and liquid coolant, respectively. The heat sink has a dimension of L x 3 L z 3 L y = 10 3 10 3 0.9 mm 3 . The optimal geometric parameters for the one-layered MCHS have been obtained in our previous work.…”

“…1 However, there still exist many disadvantages including high pumping power requirement and poor uniformity of temperature distribution at the cooling surface. Recently, Xie and colleagues, [2][3][4][5][6] Hajmohammadi et al, [7][8][9][10][11][12] and Wang and colleagues [13][14][15][16][17][18] conducted many relevant works to improve the cooling 1 performance of the MCHS. For example, Xie and colleagues 2-6 studied the wavy MCHS and proposed some new MCHS structures with multistage bifurcations or with constructional vertical Y-shaped bifurcation plates.…”
