Which side of Peltier is cold?
Cooler Modules Place the module on a flat surface so that the wires are pointing towards you with the positive (red) wire on the left hand side and the negative (black) wire on the right hand side. In this orientation the cold side will be facing down and the hot side will be facing up towards you.
How do you connect the Peltier in series?
If your peltiers are rated at 12 volts, and you’re using a 12 volt supply, you should be connecting them in parallel, not series. Connecting them in series divides the voltage across them, so each peltier is seeing only 1/nth of the supply voltage.

How hot can a Peltier module get?
200 °C
There are temperature limits, when operating Peltier elements. They are available with a maximum operation temperature of 200 °C, where this limit is defined by the reflow temperature of solder and sealing. Another limit is the maximum temperature between the hot and the cold side of a Peltier element.
Can you stack Peltier modules?
Directly stacking Peltier modules is problematic in practice. The heat-sinking required is substantial. You can think of a Peltier serial array (stacked) within a system as a machine that must must be ‘started’. If the heat sinking is too substantial, it takes forever to start the heating/cooling.
How much area can a Peltier cool?
Using a 12 V power supply,the 12706 device at 35°C (hot side) draws 5 amps (12 volts by 5 amps = 60 watts) (heat flux); this device can transfer about 20 joules per second (going by the data sheets and the cold side would be at -10°C). At that rate, it’ll take about 4200 seconds to cool that volume by 1°C.
How do you increase Peltier efficiency?
The three most common ways for improving the Peltier element efficiency in case of cooling are:
- Reducing dT – optimize heatsink and fan.
- Minimize power losses – isolate the cooled area.
- Optimize COP – Select Peltier element of adequate power.
