Fabrication and characterization of microscale heat sinks

2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC), 2016
In the field of thermal management, engineers are well aware of the challenges posed by the increasing level of dissipation. Among the many possible solutions to counter the threat of overheating, one is dealing with the usage of microscale heat exchangers, where the forced air or liquid cooling solution is integrated into the electronic package itself.

Heat transfer performance investigation of the spherical dimple heat sink and inclined teardrop dimple heat sink

Numerical Heat Transfer, Part A: Applications, 2019
The convective heat transfer is significant in the cooling channel, but the heat transfer enhancement in a cooling passage will be more useful or increases if a dimple is employed on their surfaces...

Heat Transfer in Spiral Channel Heat Sinks

ASME 2011 9th International Conference on Nanochannels, Microchannels, and Minichannels, Volume 1, 2011
Heat transfer in a spiral heat sink is examined experimentally and analytically. The spiral channel was fabricated on a base plate of copper. The cross section of the channel is square with 1 mm sides. A copper cap plate was bolted tight to seal the channel.

Partially heated heat sinks in a zero-bypass

International Communications in Heat and Mass Transfer, 2012
Abstract The need to improve the thermal performance of heat sinks remains a design priority for thermal engineers. Most of the considerations so far have involved various shapes and sizes of the fin designs. This numerical study evaluates the influence of the heating position on the thermal performance of a plate-fin heat sink in a zero-bypass ...

Measurements of heat transfer in microchannel heat sinks

International Communications in Heat and Mass Transfer, 2000
Abstract The paper presents new experimental measurements for pressure drop and heat transfer coefficient in microchannel heat sinks. Tests were performed with devices fabricated using standard Silicon 100 wafers. Two different channel patterns were studied.

Heat sink design: heat sink design for a company.

Throughout the project, I utilized SolidWorks Software to design, assemble, and simulate a heat sink for a heat sink company with a computer science background that needs it to be used on a silicon computer chip. The primary objective was to design a heat sink that could lower the temperature of the silicon chip to less than 43.5ºC.
