Phonic has now brought to market solid state heat transfer using the Peltier effect which is explained in the article below. This will be a critical to cooling semis and mems in a localized manner rather than wasting energy cooling a much larger space. This will allow devices to shrink much more than if the whole device needed to be cooled. This should allow for entirely new applications for semis where space and energy are critical issues. Just like the semi world this technology will probably advance through many generations and over time revolutionize temperature control and will probably be built on larger scales using similar tools as used to build display screens and solar panels on everything from very, very small scale to entire buildings as the application advances through generations, just like all other technologies. Heat transfer is a world wide mega market that is ripe for technological change. Like all technology items, expect the cost to go down dramatically and the performance to go up just as fast. As with the manufacture of solar panels and display screens with AMAT mastering large scale fabrication, this might be a whole new frontier for them in large panels that could be used on buildings and revolutionize the industry with solid state cooling doing away with the complex mechanicals, control systems and additional distribution vents in large buildings that add to the bulk and cost. This could revolutionize heating and cooling by acting as a solid state heat pump.
Thermoelectric was assigned to the dustbin of engineering, too costly and unreliable to swap for traditional cooling systems. Phononic founder Tony Atti says he has a product that shows thermo’s time has come, and deals with Unilever and Pepsi Bottling to prove it.
