I |
Operating Current to the TEC module (in Amps) |
Imax |
Operating Current that make the maximum temperature difference ∆Tmax (in Amps) |
Qc |
Amount of heat that can be absorbed at the cold side face of the TEC (in Watts) |
Qmax |
Maximum amount of heat that can be absorbed at the cold side. This occurrs at I = Imax and when Delta T = 0. (in Watts) |
Th |
Temperature of the hot side face when the TEC module operatiing (in °C) |
Tc |
Temperature of the cold side face when the TEC module operating (in °C) |
∆T |
Difference in temperature between the hot side (Th) and the cold side (Tc). Delta T = Th-Tc (in °C) |
∆Tmax |
Maximum difference in temperature a TEC module can achieve between the hot side (Th) and the cold side (Tc). This occurrs (Maximum cooling capacity) at I = Imax and Qc = 0. (in °C) |
Umax |
Voltage supply at I = Imax (in Volts) |
η |
TEC module cooling efficiency ( %) |
α |
Seebeck coefficient of thermoelectric material (V/°C) |
σ |
Electrical coefficient of thermoelectric material (1/cm·ohm) |
κ |
Thermo conductivity of thermoelectric material (W/CM·°C) |
N |
Number of thermoelectric element |
Iεmax |
Current attached when the hot side and old side temperature of TEC module is a specified value and it required getting the Maximum efficiency (in Amps) |
