Thermoelectric Cooler Physics
Cooling Power
Qc = α*Tc*I - 0.5*I²*R - K*(Th - Tc)
Input Power
Pin = α*(Th - Tc)*I + I²*R
Coefficient of Performance
COP = Qc / Pin
Hot-Side Rejection
Qh = Qc + Pin
Operating current is set at 4.00 A, with Seebeck coefficient α = 0.045 V/K.
Maximum cooling power occurs at optimum current: I_opt = (α * Tc) / R ≈ 6.75 A.
Joule heating (0.5 * I² * R) creates a thermal barrier that reduces net cooling at higher currents.
