The regular perturbation method is used to solve the hyperbolic temperature evolution equation with weak nonlinear terms for a one-dimensional isolated rigid system. Some dynamic and thermodynamic aspects (e.g., the wave speed and the evolution of the entropy) are analyzed. The existence of thermal wave fronts and heat flux solitons for a non-isolated rigid system is shown analytically.
