A full 3-dimensional (3D) conjugate heat transfer model has been developed to simulate the heat transfer performance of siliconbased, parallel microchannel heat sinks. A semi-normalized 3-dimensional heat transfer model has been developed, validated and used to optimize the geometric structure of these types of microheat sinks. Under a constant pumping power of 0.05 W for a water-cooled microhe...

In this study, the air-side pressure drop and heat transfer performance of plate-fin and microchannel coils were tested under clean and fouled conditions. The heat exchangers were tested with two different types of dust, ASHRAE dust and Arizona Road Test Dust. The ASHRAE dust was found to have a very significant impact on the pressure drop of the microchannel heat exchanger, increasing the air-...

In this study, the air-side pressure drop and heat transfer performance of plate-fin and microchannel coils were tested under clean and fouled conditions. The heat exchangers were tested with two different types of dust, ASHRAE Standard Dust and Arizona Road Test Dust. The ASHRAE dust was found to have a very significant impact on the pressure drop of the microchannel heat exchanger, increasing...

• Microchannel heat sinks are modelled by conjugate transfer and laminar flow CFD. Four performance enhancement tape inserts tested individually combined. Tape axial twist improves the Nusselt number gains to hydraulic loss trade-off. With best heated base is 16 ℃ cooler at 100 W/cm 2 flux input. Sealing in barrel prevents tip leakage raises conduction. The continuous power increase miniaturiza...
