Unlike conventional compressor
refrigeration systems, thermoelectric cooling modules (TEC or Peltier device)
are solid state cooling systems that incorporate semiconductor technologies
and electronic assembly techniques. Thermoelectric cooling modules are
solid-state, vibration free, noise free, and freon free heat pumps with MTBF
200K hours. They are modular devices, and are simple to install and operate
at direct current voltage. Since they consist primarily of thermoelectric
material sandwiched between ceramic plates and have no moving parts, they
are inherently reliable. The modules represent the best of high science and
technology. These incredible miniature heat pumps raise or lower temperature
in a small area almost instantly. Current applied to the device will produce
heat
on one side and
cold
on the other side,
up to 68ºC difference between the two sides. Modules can be mounted
in parallel to increase the heat transfer effect or can be stacked to achieve
high differential temperatures. They are widely used in industrial
areas, for example, military, aviation, space flight, electronics, medical
instruments, laboratory, portable cooler/warmer, and so on.

TYPICAL PERFORMANCE
Cooling an object from room temperature to freezing is a typical
thermoelectric application. As an example, assume that the object (electronic
device or picnic box) produces or takes in from the environment 20 watts
of heat. A thermoelectric cooling module will remove this 20 watts via its
cold surface and deposit it on its hot surfaces. This 20 watts plus the power
input to the TEC must be transferred to the atmosphere by means of a heat
sink. A fan is recommended to put on a heat sink. Selecting a proper heat
sink is very important when you design a thermoelectric cooling system. Usually,
temperature of a heat sink rises 10ºC above ambient temperature after
TEC applied a proper voltage when the cold side of TEC is without any heat
load. You MUST increase the size of heat sink and fan or reduce voltage
input to the TEC to achieve better performance if the temperature of the
heat sink is over 10ºC above ambient temperature when no heat load attached
to the cold side of TEC.
Ambient temperature (Ta)=25ºC
(77ºF)
Desired cold temperature of TEC (Tc)=0ºC (32ºF)
Heat to be removed (Q)=20 watts
Hot side temperature of TEC (Th)=50ºC (122ºF)
Delta T (DT) = Th - Tc = 50º - 0ºC = 50ºC
Therefore, you should select the TEC that can pump out at least 20 watts heat (Qmax = 20 watts) from our product list. For more information, please download our Thermoelectric Cooling Module (TEC) Application Note and Brief TEC Installational Procedure.

FAQ:
Q: Which side of TEC is hot side?
A: The two wires attached side of TEC is hot side if the
red/black wire is connected to positive voltage/ground respectively.
Q: Which wire is positive polarity and which wire is ground?
A: Usually, the red wire is positive and the black wire is
ground. The hot side and cold side of TEC can be swapped if the red/black
wire polarity is swapped.
Q: After TEC was applied voltage, it does not create one hot
side and one cold side.
A: You may not mount a proper heat sink with a fan on hot side
of TEC. The heat created by hot side of TEC did not be transferred
to ambient through heat sink, then it transfers back to cold side of TEC.
Q: What is operating voltage for a TEC?
A: The different TEC has a different operating voltage. For
TEC1-12706 and TEC1-12703, the efficient operating voltage is from +5VDC
to +12VDC. For TEC1-7103, the efficient operating voltage is from +3VDC
to 6.5VDC. Heat pump power is proportional to voltage power.
Q: How big heat sink is required by a TEC?
A: For TEC1-12706, a 80x80x25mm heat sink with a same size
of DC fan is required. For TEC1-12703, a 60x60x20mm with a same size of DC
fan is required. For TEC1-7103, a 50x50x15mm heat sink with a same size of
DC fan is required. Of course, a bigger heat sink on hot side of TEC has
a better performance of TEC.
