RAM Electronics's Description
Thermoelectric coolers (TEC or Peltier) create a temperature differential on
each side. One side gets hot and the other side gets cool. Therefore, they can
be used to either warm something up or cool something down, depending on which
side you use. The Thermal Tape listed below works very well to attach heat
sinks to the hot side.
This Peltier works very well as long as you remove the heat from the hot
side. After turning on the device, the hot side will heat quickly, the cold
side will cool quickly. If you do not remove the heat from the hot side (with a
heat sink or other device), the Peltier will quickly reach stasis and do
nothing. We recommend using an old computer CPU heatsink or other block of
metal to pull heat from the hot side. We were able to use a computer power
supply and CPU heatsink to make the cold side so uncomfortable we could not
hold our finger to it.
