An improved design of double-layered microchannel heat sink with truncated top channels

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

“…(20), the total pressure drop is the sum of the pressure drop between the first and second layer. Similar observation is reported by previous researches [12,31]. By combing Eqs.…”

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

“…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.…”

A comparison of micro-structured flat-plate and cross-cut heat sinks for thermoelectric generation application

“…Leng et al [3], improved design of double-layered microchannel heat sink with a proposed truncated top channel. They investigated effect of total pumping power on the performance of the proposed design, where they showed that the maximum temperature difference on the bottom wall is reduced by 37.5% compared to the original design of double-layered microchannel heat sinks for the same pumping power.…”
