Electric vehicles are poised for a rapid growth phase with the combined effect of longer range, lower battery cost and faster charging rate. In particular, sales of plug-in electric vehicles (PEV) have tripled since 2013 and continue to grow at over 40% a year. It is expected that at these growth rates, 8 out of 10 new cars sold globally in 2030 will be a PEV. In some countries … [Read more...]
Does a 10°C Increase in Temperature Really Reduce the Life of Electronics by Half?
This may seem like a silly question to ask in a magazine entitled “Electronics Cooling”, but why do we really care what temperature of electronics really is, anyway? The simple answer to that question is that it is universally recognized that electronics reliability when devices are too hot for too long of a time. The difficult answers to the question are in defining exactly … [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...]
