1] is the Peltier coefficient, [alpha] is the Seebeck coefficient
B] are the absolute Seebeck coefficient
of each conductor, and [[alpha].
Typical thermocouples (TCs) are made from two different conductors, one with a large positive Seebeck coefficient
and the other with a large negative coefficient-- for example, iron at +18.
The fabricated thermopiles typically have a resistance of 20 K[OMEGA] and showed a Seebeck coefficient
8 [micro]V/K) suggesting a weak Seebeck coefficient
that typically shows a metallic behavior.
Thermal properties: Seebeck coefficient
and electric resistance.
We have employed finite element analysis to develop computational Seebeck coefficient
where S is the Seebeck coefficient
for the material, T is the absolute temperature, p is the electrical resistivity of the material and k is the thermal conductivity of the material.
a]--the Seebeck coefficient
defined as the 'thermoelectric power' of material (see Table 1); [T.
There are several important coefficients of the element that must be evaluated before creating the cooling module: the module's effective Seebeck coefficient
2]/[rho][kappa], where [alpha] is the Seebeck coefficient
, [rho] is the electrical resistivity, and [kappa] is the thermal conductivity, which includes the contributions from both carriers and phonons, i.
Note that the Seebeck coefficient
is sometimes called the thermal EMF coefficient or thermoelectric power.
