Peltier junction thermoelectric cooler tec heat pump 28
This offer is for a lot of 28 new devices as pictured
Peltier Junction, Thermoelectric Cooler, TEC, Heat Pump all these names refer to the same devices. The property of these is that when a DC voltage is applied one side gets cold while the opposite side gets hot. They are so efficient that they will self destruct if measures aren't taken to draw the heat off the hot side (heatsink) therefore the experimenter is encouraged to thoroughly research these devices before courting disaster. Properly utilized these like other semiconductors will enjoy a very long and dependable life. The possible applications for these go far beyond the simple heating or cooling of coffee and beer; sensitive optic systems perform better when kept very cool, controlled temperature of chemical reactions, heating or cooling of small engines, climate control of special garmets, the possibilities are myriad. Another property of these is that when one side is heated; they will generate electrical energy; waste heat can be recycled in this application..Here's the data: Size is 40mm (1.58") x 44mm (1.73") x 3.3mm (.13"), deltaT=79deg, Imax=8.1A, Vmax=16.1V, Thot=50deg C, Qmax=80.6W Made in USA by Tellurex under their P/N CZ1-1.4-127-1.14. a wealth of data is available on the internet. These are some of the largest of their kind and are calles 'Super Peltier Junctions' several can be laid out in an array to cover a large area or they can be stacked and the temperature differential becomes additive with the theoretical cold side ultimately reaching absolute zero as more (progressively smaller) devices are stacked on. This offer is for a lot of 28 new devices as pictured. These are factory new with wires attached ready for service.
