Multi-Physics Coupling Analysis For Thermoelectric Module

There are three thermoelectric mechanisms: the Seebeck, Peltier and Thomson effects. The Seebeck effect describes the conversion of temperature differences directly into electricity; an applied temperature gradient causes charged carriers in the material to diffuse from the hot side to the cold side generating a current flow. The Peltier effect describes the production of heat at an electrified junction of two different materials, the forced flow of charged carriers creates a temperature difference, and the Thomson effect describes the heating or cooling of a current carrying conductor in the presence of a temperature gradient. To analyze these phenomena accurately the thermoelectric field equations have to be solved, here the Seebeck‐ Peltier effect is implemented using the weak form. Otherwise, this study also investigates the temporal evolutions of the temperature profile while the TE modulus coupled to a CPU. Results give a useful phenomena explanation for the cooling application in electronic devices and figure out the interface effect of TE modulus
