Convert thermal conductivity to resistivity
WebWith S the Seebeck coefficient, T the temperature, κ the thermal conductivity and ρ the electrical resistivity. A good thermoelectric material requires the maximization of the power factor S 2 / ρ and the minimization of thermal conductivity κ. Moreover, the conversion efficiency increases with temperature. Webreplaced with the resistivity. As the resistivity has a value specific to the conductor material, the value of thermal conductivity is also specific to the material. Based on the equation for Rth, in order to reduce the thermal resistance for thermal conduction, it is necessary to increase the cross section of the object, decrease the length of the

R-value (thermal insulance factor) is a measure of thermal resistance. The higher the R-value, the greater the insulating effectiveness. Thermal insulance has the units [ (m 2 .K)/W] in SI units or [ (ft 2 ·°F·hr)/Btu] in imperial units. It is the thermal resistance of unit area of a material.
WebConductivity Converter. Conductivity is a parameter used to describe the ease of charge flow in a substance. In the formula, conductivity is represented by the Greek letter σ. The standard unit of conductivity σ is Siemens/m (S/m), which is the reciprocal of the resistivity ρ, i.e. σ = 1/ρ. ⇄. Convert. Recent conversions ...
