EXAIR’s digital ETC (Electronic Temperature Control) Cabinet Cooler® System keeps electrical enclosures cool while minimizing compressed air use. Independent laboratory tests now certify that the ETC™ is CE compliant to assure safe operation in a wide range of cooling applications. The ETC accurately maintains a constant temperature in the electrical enclosure that is slightly … [Read more...]
Graphite Foam Promises Longer-Lasting LEDs
A new graphite foam cooling system developed at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee may soon allow LED lamps to go much longer between fixture replacements. The graphite foam works by passively wicking heat away from the lamp via its lightly packed, open skeletal structure – and given that a 10-degree decrease in operating temperature … [Read more...]

Ultra-Thin Waterproof Piezoelectric Speaker Murata Electronics North America recently launched an ultra-thin waterproof piezoelectric speaker. With a thickness of only 0.9mm, this 19.5mm x 14.1mm speaker enables greater design freedom for the rapidly growing and evolving mobile market. The speaker achieves IPX7 grade waterproof protection without the need of a waterproof … [Read more...]
what's happening
Melting-While-Cooling Silicon Could Improve Solar Cells Researchers at the Massachusetts Institute of Technology (MIT) have recently discovered that by dissolving certain metals into silicon, they can add that silicon compound to the relatively short list of exotic substances that exhibit retrograde melting. Their accomplishment could ultimately result in less expensive solar … [Read more...]
Calculation Corner: Using Vendor Data to Estimate Thermoelectric Module Cooling Performance in An Application Environment
The application of thermoelectric devices to cool electronic components has been of interest to thermal engineers for many years. Thermoelectric (TE) cooling modules offer the potential to either reduce component operating temperatures at a given heat load, or allow higher component heat dissipation at a given temperature level. Readers who are unfamiliar with TE cooling … [Read more...]
