March Issue of Qpedia Thermal eMagazine - Electronics Cooling Publication from ATS

Norwood, MA, April 14, 2010 --(PR.com)-- Advanced Thermal Solutions, Inc. (ATS), has just posted its Qpedia eMagazine, the premier publication in electronics thermal management, on its site, www.qats.com. In this issue, the following articles appear:

Critical Heat Flux of Boiling in Microchannels
A liquid-cooled microchannel heat sink has been shown to be a very effective way to remove high heat load. The single-phase liquid cooled microchannel has been used in many performance-critical applications such as laser diodes, RF power amplifiers and CPU cooling systems.

Long Term Thermal Grease Reliability
Among the different TIM options, thermal greases typically offer the best thermal performance and reduced manufacturing cycle times though, depending on the application method, assembly can be messy. Thermal greases have the ability to flow and conform to interfaces, do not require post-dispense processing such as curing, and have higher effective thermal conductivity compared to other classes of materials.

Using Silicon Microchannel Heat Sinks for Thermal Management
If high pressures with relatively low flow are allowable in a design, the microchannel heat sink is a very attractive option that can perform better than most coldplate designs. Reliability concerns about fittings or connections are heightened because of the increase in fluid pressure at the outlet of the pump and inlet of the cold plate.

Tubing Material Selection for Liquid Cooling
Tubing can play a large role in the long term reliability of the solution. It is important to fully understand tubing characteristics, how they relate to evaporation, and how the loss of liquid affects the operation of the system (including pump cavitation and air blockage in a cold plate).
