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.
