Preliminary Output Power Performances Analyses and Optimization of a Thermoelectric Module

The output electrical characteristics of a simple thermoelectric module consisting of two thermoelements are discussed theoretically. And the output power, area-specific power and weight-specific power are formulated as the function of the length and cross-section area of the thermoelements, load electrical resistance and the coolant heat-transfer coefficient. A preliminary analysis and geometric optimization are then undertaken to reveal the dependences of the power characteristics of the thermoelectric module.
