$\mathrm{T}_{\kappa}$: Desired Temperature $(\mathrm{K})$

$\mathrm{T}_{\mathrm{a}}$: Ambient Air Temperature (K)

$\mathrm{k}$: Thermal Conductivity $(\mathrm{W} / \mathrm{m} \mathrm{K})$

h: Heat Transfer Coefficient $\left(\mathrm{W} /\left(\mathrm{m}^{2} \mathrm{~K}\right)\right)$

Output(s)

P: Electrical Power (Watt)
