A team of researchers from Pennsylvania State University have recently developed a blend of ferroelectric polymers that could cool chips and small scale systems on demand. According to NewElectronics these are called electrocaloric materials, and typically an external field is required for them to operate correctly, but the “latest polymer blend can hold absorbed heat even … [Read more...]
Formula Developed for Heat Transfer Between Near-Field Bodies
Alejandro Rodriguez, a researcher at Princeton, and colleagues at the Massachusetts Institute of Technology have come up with a formula that describes the maximum heat transfer between near-field objects in a recent study. Phys.org claimed that “with this new formula, engineers will know how much more performance can be squeezed out of their structural and material … [Read more...]
New Power Electronics Will Allow Army Vehicles’ Electronics to Operate at High Temperatures
The US Army has awarded GE Aviation with a contract to develop silicon carbide-based power electronics that will allow high-voltage, next-generation ground vehicles to operate at higher temperatures. "The US Army's implementation of [this technology for] more electric ground vehicles, facilitates significant improvements in size, weight and power for high temperature … [Read more...]
Overheating Causes 911 System Failure
Due to a problem with the computer cooling system, 911 service was down for about four hours recently in Buffalo, New York’s Erie County. According to Time Warner Cable News, the room at the Public Safety Campus that houses the 911 Dispatch overheated last Wednesday, and the county isn’t sure why the backup systems failed, but they are “working with partner companies to find … [Read more...]
Smart Clothing That Automatically Cools Itself
VTT Technical Research Centre of Finland Ltd has recently developed a technology that can be utilized in smart fabrics and clothing to cool or warm the wearer according to his or her needs as part of their Smart Clothing project. This new technology essentially determines the wearer’s body temperature, and automatically adjusts accordingly so “the thermal sensation of the … [Read more...]
