A group of researchers at the University of California, Riverside Bourns College of Engineering have developed a technique to keep cool a semiconductor material used in everything from traffic lights to electric cars. Gallium Nitride (GaN), a semiconductor material found in bright lights since the 1990s, is used in wireless applications due to its high efficiency and high … [Read more...]
Fan and Filter Units Prevent Hot Spots
Rittal’s TopTherm fan-and-filter units are a synthesis of radial and axial fan technologies that deliver a combination of high pressure stability and large volume air flows. Unique to this fan technology, the air outlet direction is diagonal to the outside rather than in the fan's axial direction. This approach favors an even distribution of air in the enclosure or housing, and … [Read more...]
Hot Spots in Data Centers
Heat loads of data processing equipment continue to increase at a rapid rate. This increasing heat load has been documented by a Thermal Management Consortium of 17 companies [1] as shown in Figure 1. Also shown in this figure are measured heat fluxes (based on product footprint) of some recent product announcements. The most recent shows a rack dissipating 28,500 watts, … [Read more...]
