Zusammenfassung:	A nonlinear model of anisotropic rigid heat conductor is developed in the framework of weakly nonlocal Extended Irreversible Thermodynamics.The restrictions placed on the constitutive functions by the principles of dissipation and material frame indifference are investigated. Nonlinear anisotropic Guyer–Krumhansl and Maxwell–Cattaneo equations are derived. Comparison is made with some other models existing in the literature.
