Hello everybody,
I am wondering how to use peltier module (EVL31-050) as a heater?
I have a Al block that I want to heat it up by putting the cod side of the peltier module on it. the other side is in floating in air(ambient). I am wondering which side is working as a reference for temperature. If I connect the peltier module to a power supply , by increasing the voltage, how the temperature varies in both sides? if I have temperature increase in one side and the floating side keeps the same temp as ambient temperature or both have increase and decrease in temperature?
Thanks for ur help
You cannot make it get hot or cold alone. When you apply voltage one side becomes hot while the other side gets cold, this is called peltier effect.
In your case if you want to make a heater make use of the hot side alone, the cold side should have a heatsink and fan to dessipate the cold.
Hope you are clear now
