Thinking about a Pelt setup. - Page 2

post #11 of 13
Just some clarification: The Qmax is the temperature differential between the hot and cold sides of the peltier- a QMax of 65 means that there is a maximum of 65C difference between the hot/cold sides. The Wattage rating is the maximum amount of energy in watts that the TEC can transfer across itself. Keep in mind that energy != temperature.

NO Qmax is the maximum heat transferred from one side to the other not the maximum temperature difference between the 2 sides that’s "dTmax"

A TEC with a heat load = to Qmax and the voltage at Umax the temp difference between the sides should be 0 or the hot and the cold side will be the same temp

Umax the Maximum input volts
Imax. The maximum amps drawn at max volts (Umax) with no load
Qmax. The maximum heat transferred at max volts (Umax)
dTmax. The maximum temperature difference between the hot side and the cold side when no load is applied to the cold side.

Ah, sorry about that- I did get QMax and dTmax mixed up. QMax is measured in Watts, while dTMax is measured it degrees Celsius.
