Laird Technologies, Inc. recently announced the release of its enhanced Tlam™ SS LLD for use as a thermally conductive printed circuit board (PCB) substrate. The Tlam SS LLD is a versatile, thermally enhanced PCB substrate system specifically designed for heat dissipation in bright and ultra-bright LED module applications. The thermally conductive PCB substrate provides 8-10 … [Read more...]
Researchers Cool Down Supercomputers with Warm Water
A team of IBM researchers in Switzerland is experimenting with a micro network of copper tubes that run through smaller, clustered computer servers and whisk away heat with the help of warm water. Liquid cooling, even with warm water, is 4,000 times more effective than air cooling at removing heat, they say. Researchers from IBM and the Swiss Federal Institute of Technology in … [Read more...]
Toward Liquid-Cooled Computers
Experts say a new technique called superwicking could provide a better way to cool computer hardware and could help remove one of the biggest barriers to a new generation of high-powered microprocessors. And in the meantime, it could prove a boon to tiny fluid-based sensors. Optical physicists Chunlei Guo and Anatoliy Vorobyev of the University of Rochester in New York state … [Read more...]
Air-Cooled, Pin Fin Coldwall Design For Operation At Altitude
Introduction Numerous thermal management techniques exist depending on the system, application, and power level. For airborne electronic systems, the most direct approach to thermal management would be to use ambient air or chilled air, provided by the aircraft, routed to and blown across the electronics. However, in some applications potential contaminants in the cooling air, … [Read more...]
Using a simple air recirculation model to explore computer rack cooling
Figure 1. Schematic diagram of simple computer rack air recirculation model. Figure 2. Schematic diagram of computer rack air recirculation model with heat exchanger in rear of computer rack. In an article in the November 2006 issue of ElectronicsCooling it was noted that “advances in computer clusters have resulted in the introduction of higher density server … [Read more...]
