Introduction The electronic industry requires increased forced-air cooling limits to cool high-end server CPUs adequately. Improving air-cooled heat sink thermal performance is one of the critical areas for increasing the overall air-cooling limit. One of the challenging aspects for improving heat sink performance is the effective utilization of relatively large air-cooled fin … [Read more...]
Estimating Temperatures in an Air-cooled Closed Box Electronics Enclosure
Introduction In the majority of air-cooling applications, openings or vents are provided in the enclosure or box in which the electronic components are housed. The required cooling air is drawn in from outside the box by fans or blowers. In some applications, however, there may be airborne particulates or other substances in the air that would be injurious to the electrical … [Read more...]
ASHRAE Committee Formed to Establish Thermal Guidelines for Datacom Facilities
Introduction The environment of every data center is complex and unique. Air currents within the data center have hot and cold air streams colliding, cold air exhausting upward from perforated tiles, hot air streams exhausting from tops and the rear of servers and storage racks. Not only are these air circulation patterns extremely complex, they can also be transient in nature … [Read more...]
Use Of Heat Pipe Cooling Systems In The Electronics Industry
Introduction Thermal management of electronic components must solve problems connected with the limitations on the maximum chip temperature and with the requirements on the level of temperature uniformity. To cool electronic components, one can use air and liquid coolers as well as coolers constructed on the principle of the phase change heat transfer in closed space; i.e., … [Read more...]
Seven Years Of Technical Data: An Overview
The first 1997 issue of ElectronicsCooling started with a Technical Data column, the first of a still continuing series of columns devoted to data that are of interest to thermal designers. In the author's opinion, it is high time to come up with an overview of all items that have been covered over the past seven years. As is obvious from the table, the majority of columns … [Read more...]
