PELTIER JUNCTION THERMO-ELECTRO DEVICE
PELTIER HEAT PUMP
High tech comes to Am Sci & Surp!! It is here in the form of a
Peltier junction, a thermo-electric device that translates electric
power into heat, and perversely, into cool. Apply current @ 3-12 VDC to
the gizmo and it extracts thermal energy from one face, thereby cooling
it. The heat is dumped onto the other face, thereby heating it.
Please note: you must use a heat sink on the hot side or the junction
will fry itself, since it can quickly create a 65° C temperature
differential in a no load situation. Stack two, or build a cascade to
increase the thermal differential created. Or run it backwards. Apply
heat or cold to the relevant face and produce a current. Amazing for
science projects and experiments. Practical for coffee warmers, beer
coolers and mini-refrigerator or warming oven applications. Comes with
instructions. Large is 1-9/16" sq. x 3/16" thick.
