How Peltier Cold-Side Heat works
Estimate thermoelectric cooler heat absorbed at the cold side as αITc−½I²R−K(Th−Tc). Supply module-level Seebeck coefficient, electrical resistance, and thermal conductance; positive output means cooling. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Cold Side Heat W
- The resulting cold side heat w returned as a number.
Limitations and assumptions
- Peltier heat-pumping estimates depend on hot- and cold-side temperatures, current, Seebeck coefficient, electrical resistance, thermal conductance, contact resistance, and heat-sink performance. Maximum heat pumping and maximum temperature difference do not occur at the same operating point.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

- Required Heatsink Thermal Resistance
Calculate maximum allowable heatsink-to-ambient thermal resistance from junction-temperature limit, ambient temperature, dissipation, junction-to-case, and case-to-sink resistances. A negative result means the assumed stack cannot meet the limit.
- PCB Via Current from Thermal Model
Estimate via current from an allowed temperature rise and user-supplied effective thermal resistance using I=sqrt(ΔT/(R_electrical·R_thermal)). Barrel electrical resistance uses copper resistivity, length, and plated annulus area. This simplified lumped model requires board-specific thermal resistance.
- Power Dissipation from Temperature Rise
Infer steady-state power dissipation as (Tj−Ta)/θJA from a measured junction and ambient temperature. Use the effective thermal resistance for the same assembly and cooling conditions.
