Micromachined Heat Sinks

SAE Technical Paper Series, 1999
<div class="section abstract"><div class="htmlview paragraph">A silicon micromachined heat sink is presented. The device uses liquid cooling in microchannels to remove high heat fluxes. Deep reactive ion etching and multiple wafer bonding is employed to fabricate high aspect ratio, enhanced heat transfer surfaces and a flow channel network ...

Characterization of Heat Sink Flow Bypass in Plate Fin Heat Sinks

Heat Transfer, Volume 5, 2002
Experimental testing has been performed on two plate fin heat sinks in order to examine flow bypass phenomenon. The present study examines pressure drop and thermal resistance as well as flow velocities within the heat sinks. Tests are performed for bypass channel/fin height ratios of 0.25, 0.5, 0.75 and 1 with approach velocities from 2 to 8 m/s.

A method to rank heat sinks in practice: the heat sink performance tester

Semiconductor Thermal Measurement and Management IEEE Twenty First Annual IEEE Symposium, 2005., 2005
One way of cooling electronic devices is through enlarging the surface that is in contact with a fluid (usually air) by attaching a heat sink. Since literally thousands of heat sinks are available many designers are confronted with the question: which one? Very often the designer's choice is based on cost and manufacturer's data.

Kinetic Heat Sink

International Symposium on Microelectronics, 2010
Conventional heat sinks for processors achieve improved heat transfer efficiency by impinging ambient air over stationary fins. Further improvement in the air film heat transfer coefficient through increased air speed becomes asymptotic and invariably results in undesirable acoustic noise.
