Researchers at the Tyndall National Institute at University College Cork in Ireland have found a new way of cooling semiconductors in computers, mobiles and games consoles to improve their performance and reduce energy consumption. Most computers have thermal interface materials (TIM) to join the chip with the heat sink, with solder or a thin, film-like sheet. Solder is … [Read more...]
Enhanced Cascade Series Thermoelectric Assemblies
Laird Technologies, Inc. released its enhanced Cascade Series Thermoelectric Assemblies (TEAs), custom-designed cooling assemblies that use multistage Thermoelectric Modules (TEMs) to achieve a high temperature differential from ambient. This product series can produce up to a 40% higher cooling capacity at cold temperatures, surpassing standard product offerings with similar … [Read more...]
Cooling High-Power Electronic Components in Small Packages
Thermacore’s Therma-Base vapor chamber is used as the base of a heat sink to alleviate spreading resistance found in solid heat sink construction, which enables lower device temperature and greater component reliability. The chamber features effective thermal conductivity over 5,000 W/mK; application improvement of over 30% in high-flux, poor spreading applications; and over … [Read more...]
Electronic Temperature Control Cabinet Cooler System Now CE Compliant
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...]
