by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Electronics cooling engineers and designers are used to one constant in their professional lives: change. Most of it (as far as problem solving is concerned) is change for the worse… and is challenging! The heat flux keeps increasing, the geometries keep shrinking, the available solution … [Read more...]
Ultra-Thin Thermoelectric Cooler Provides Precise Temperature Control for Optical Electronics
Phononic recently announced its pico-TEC series, a high-performance solid-state thermoelectric module (TEM) designed to provide precise temperature control in order to meet the unique thermal management requirements of optoelectronics and fiber optic modules. The pico-TECs are manufactured using advanced automated semiconductor fabrication technology and ultra-thin form factor … [Read more...]
Thermoelectric Modules That Achieve Higher Heat Flux Densities For Cooling Industrial Lasers
Laird has recently developed a high heat flux density thermoelectric module (TEM) designed to achieve a higher heat pumping capacity than standard TEMs, called UltraTEC. “The UltraTEC Series TEM has a heat pumping capacity up to 340 watts, which is ideal for larger cooling applications with limited surface area such as industrial lasers,” claimed Laird. It also has a “precise … [Read more...]
New Material Cools Solar Cells Yet Absorbs Sunlight
Recently, researchers from Stanford University have achieved a combination of cooling and maintaining sunlight absorption with a wafer made of silica to better cool solar cells, according to BusinessWire.com. BusinessWire.com explained, “The researchers etched tapered holes, about 6 micrometers across and 10 micrometers deep, in the wafer. The holes are designed to smooth the … [Read more...]
Electrocaloric Polymers That Create On-Demand Cooling
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...]
