As an increasing number of hybrid-powered vehicles move from concept to completion, technology is battling to keep pace with some of the less-publicized technical challenges found among the complex electronics aboard these land- and air-based vehicles, computers and other devices. For instance, how do you effectively cool the electronics in a high-power electric motor that propels a passenger car from 0-60mph in under 10 seconds and uses regenerative braking to stop? Researchers in the U.S. believe the secret may lie in understanding precisely how fluid boils in tiny ‘microchannels’, which has led them to develop formulas and models that will help engineers design unique systems to cool high-power electronics found in today’s and tomorrow’s devices.

The availability of increasingly powerful computer graphics cards is placing ever-greater demands on keeping things cool “under the hood”. Certain to have gaming enthusiasts sitting up and taking notice is BFG Technologies' announcement of the release of two NVIDIA GeForce GTX 200 series graphics cards featuring their built-in liquid cooling solutions. Designed to be installed “out of the box and maintenance-free”, the GTX 285 H20+ and GTX 295 H20C offer high performance water-cooled video cards without the fuss. Read More
Liquid-cooled PCs are a mainstay for PC enthusiasts looking to eek every last bit of performance from their beloved machines and now it seems this approach has reached the world of the LED light bulb. A company called Eternaleds has introduced the HydraLux-4 LED Bulb, the world’s first LED light bulb to use "liquid-cooling technology" to give a true 360-degree light like a regular incandescent light bulb.

Keeping electronic components cool is a constant problem for electronics manufacturers – computer manufacturers in particular. While desktop PCs have a few options open to them, such as water-cooling, laptops are more limited in how they can be cooled. As laptops and other electronic devices continue to shrink while the heat they generate increases, the search is on for alternatives to the bulky, noisy fan-based systems widely used. A cooling system developed by Tessera has discovered a way to create a cooling airflow through ionizing air particles. Read More
