The fundamental problem in creating efficient thermoelectric materials is that they need to be good at conducting electricity, but not at conducting thermal energy, say Massachusetts Institute of Technology (MIT) researchers. That way, one side can get hot while the other gets cold, instead of the material quickly equalizing the temperature. But in most materials, electrical … [Read more...]
Heat Sink Reliability Risks from Thermal Greases
ATS Thermal Labs has published a white paper, “Long term Thermal Grease Reliability.” It considers how long term heat sink reliability is affected by the use of thermal greases as thermal interface materials. The implications are very important as they will affect the MTBF of electronic equipment. Read the paper from ATS Thermal Labs. … [Read more...]
Flir Buys Marine Electronics Company
Flir Systems Inc. recently entered into a $180 million deal to acquire marine electronics company Raymarine Holdings Ltd. Raymarine is considered a world leader in marine electronics, providing electronic equipment for recreational boating and light-commercial marine markets. Based in Portsmouth, England, it reported $170 million in revenue last year. Flir, a Portland-based … [Read more...]
Compact Water-Circulation System Prevents Stacks of Electronic Chips
A research team from the A*STAR Institute of Microelectronics and Nanyang University in Singapore has designed and built a water circulation system to cool stacks of integrated electrical circuits. “The heat must be removed from microchips to maintain a temperature within acceptable limits: less than 100 °C,” explains team-member Navas Khan from the Institute of … [Read more...]
Report: LED Lights to Capture 50 Percent of Market by 2020
A new report finds that the market for light-emitting diodes (LEDs) is set to grow substantially in the next 10 years, surpassing even compact fluorescent lightbulbs as an energy-efficient lighting option. By 2020, LEDs will cover 46 percent of the $4.4 billion U.S. market for lamps in the commercial, industrial and outdoor stationary sectors, driven by the overall push toward … [Read more...]
