Introduction With thermal solutions becoming more challenging, there is a push for novel cooling ideas or materials to further mitigate thermal issues facing today's electronics. In these design situations, the proven method of analytical calculations, modeling, and laboratory testing is sometimes bypassed in the search for a quick "cure-all" solution. Evolutionary progress is … [Read more...]
Advances In High-Performance Cooling For Electronics
Introduction The need for new cooling techniques is driven by the continuing increases in power dissipation of electronic parts and systems. In many instances standard techniques cannot achieve the required cooling performance due to physical limitations in heat transfer capabilities. These limitations are principally related to the limited thermal conductivity of air for … [Read more...]
Cooling Solutions In The Past Decade
Introduction In 1995, a typical thermal design engineer was aware that removing heat was not going to get any easier in the next few years. A look back at the past ten years reveals that thermal management remained a challenging field. Fortunately, developments and improvements in thermal management hardware have assisted the electronics packaging community by enabling higher … [Read more...]
GCS Theory Applied to Thermal Interface Materials
There are 819 kinds of Thermal Interface Material (TIM) - those greases, putties, pads and phase change compounds that go between hot electronic components and their heat sinks - and just as many ways to misuse them. This article covers all of them by stating: If a TIM disappoints, it is all your fault for making one or more of these silly mistakes. Never Learning How to Make a … [Read more...]
Liquid Cooling is Back
Introduction IBM announced its return to water cooling on April 19, 2005 with the introduction of a water cooled heat exchanger mounted to the back cover of a 19 inch rack. This is the first of the major datacom equipment manufacturers to employ water cooling for a rack of CMOS processors, using a cooling distribution unit supplying the water and rejecting the heat load to … [Read more...]
