The thermal analysis uses comprehensive models for accurate temperature prediction:
The heat transfer equation is:
$$\frac{\partial T}{\partial t} = \alpha \nabla^2 T + \frac{Q}{\rho c_p}$$
Where α is thermal diffusivity, Q is heat generation rate, ρ is density, and cp is specific heat.
The thermal resistance is given by:
$$R_{th} = \frac{T_j - T_a}{P} = R_{jc} + R_{cs} + R_{sa}$$
Where Tj is junction temperature, Ta is ambient temperature, P is power, and Rjc, Rcs, Rsa are junction-case, case-sink, and sink-ambient resistances.
The convective heat transfer coefficient is:
$$h = \frac{Nu \cdot k}{L}$$
Where Nu is the Nusselt number, k is thermal conductivity, and L is characteristic length.
