I wanted to make a more efficient cooling element for my electrically powered cooler so I went ahead and ordered the necessary parts from Amazon.com. Heatpipe heatsinks are really good at cooling CPUs (those 2 pictured can handle 160Watt TPD easily) so they are perfect for cooling 40mm Peltier chips. I used a 12volt 6amp rated Peltier for this project.
Another Peltier woodstove fan. Instructables. OKish. So I bought an EcoFan for a friend and decided that it was a cool concept and built one from scratch. The fan gets its power from a peltier element that is used in reverse, i.e. it is generating electricity from the heat given off from the stove top. More can be found on the wikipedia article on http://en.wikipedia.org/wiki/Thermoelectric_cooling
Peltier_modules are one of the modern technologies used for a wide variety of applications in many industries and in consumer’s products as well. Peltier effect which is used by this type of devices allows for precise temperature calibration, refrigerator-less and fan-less cooling, temperature sensors and hundreds of other applications.
