European Thermodynamics are pleased to announce the launch of the new JUNIOR and CyCLO pulse width modulator (PWM) thermoelectric controller electronic PCBs. Developed to work with the Adaptive® thermoelectric assemblies and thermoelectric cooler (TEC) modules, JUNIOR and CyCLO are thermoelectric controllers that enable a precise method of temperature control for sensitive … [Read more...]
Estimating Internal Air Cooling Temperature Reduction in a Closed Box Utilizing Thermoelectrically Enhanced Heat Rejection
An earlier article in this column considered the problem of cooling electronic components in a closed box [1]. In outdoor applications for example, it may be necessary to totally seal the box to prevent exposure to airborne particulates, water droplets or other sub- stances in the air that could be injurious to the electronic components. In such an application, heat picked up … [Read more...]
What a Thermoelectric Cooler is REALLY Good For…
Fairy tales… perpetual motion machines… Not all fairy tales are perpetual motion machines, but all perpetual motion machines are certainly fairy tales. Before I get into the specifics of thermoelectric coolers, however, it seems appropriate to set the stage for this particular category of fairy tales. There are two classical types of perpetual motion “machines,” called (not … [Read more...]
How Vapor-Compression Cooling Works
Vapor-compression cooling can be found in virtually any home, such as in air conditioners that remove heat from our homes and in refrigerators that store our food. The history of vapor-compression goes back to 1805 where Oliver Evans, an American inventor, described a closed vapor-compression refrigeration cycle for producing ice. The first working vapor-compression … [Read more...]
HEX 2.0 CPU Cooler Now Available
Phononic has recently announced that the HEX 2.0, its high performance small form factor CPU cooler for gaming and high performance PCs, is now available. The HEX 2.0 is a compact, but powerful CPU cooler designed to fit in small chassis, including mini-ITX cases, while delivering cooling capacity that outperforms similarly-sized 92mm coolers and many larger air or water CPU … [Read more...]
