Laminar thermal performance of microchannel heat sinks with constructal vertical Y-shaped bifurcation plates

, 2014
With increasing output power of integrated chips, the involved heat flux is accordingly increased. Traditional cooling methods failed to satisfy such a situation, and thus new cooling methods incorporating microchannel heat sinks with high capabilities ...

Heat transfer enhancement on the rectangle microchannel heat sink

Abstract Microchannel heat sink is widely used in the aera of heat dissipation of electric device. This paper establishes a numerical model of rectangle microchannel heat sink and an experimental platform for validation. To enhance the thermal performance, the models of interrupted and staggered-interrupted channels are simulated.
