Multi-parameter optimization of flow and heat transfer for a novel double-layered microchannel heat sink

Enhancement thermodynamic performance of microchannel heat sink by using a novel multi-nozzle structure

“…The overall thermal resistance of the heat sink can be calculated by Tuckerman and Pease [1], Hung et al [17], Leng et al [19] and Zhai et al [24],…”

“…Water was applied as the coolant. Their thermophysical properties are listed in Table 2 [1, 19]. The boundary conditions for the computational models were assumed as follows:…”

“…Eight years later, it was reintroduced by Wei et al [14] with the thermal resistance improved up to 0.09°C/ Wcm 2 . Recently, DL-MCHSs were continuously investigated by other groups of authors such as Hung et al [15][16][17], Leng et al [18][19][20], Lin et al [21], Rajabifar et al [22], Wu et al [23], and Zhai et al [24]. The channel inlets of the upper layer of a DL-MCHS were designed on the top of the channel outlets of the lower layer; therefore, the temperature in the lower-layer-outlet region would be reduced compared to that of the single layer leading to the temperature on the bottom wall being more uniform.…”

“…They revealed that the thermal resistance of the heat sink with sandwich structure and counter flows was much smaller than those of the single-layer and the double-layer with unidirectional or counter flow. A truncated structure of the upper layer channel of the DL-MCHS was proposed by Leng et al [19]. This truncation could improve the temperature uniformity on the bottom wall.…”

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

“…Leng et al performed an optimization study on double-layered micro channel heat sink [23,24]. Khan et al [25] performed multi-objective optimization on inverse trapezoidal microchannel heat sink.…”
