Abstract
The invention relates to a method and apparatus for determining the internal temperature and the coefficient of internal thermal conductivity of a structure. In both cases, the surface temperature and ambient temperature of an object are measured from both sides of two structures whose thermal conductivities are known. On the basis of the measured temperature values, the internal temperature or the coefficient of internal thermal conductivity of the object is determined from the function of the heat flux. Thereafter the unknown thermal conductivity or the unknown internal temperature of the object is eliminated from the solutions, and the internal temperature or the coefficient of internal thermal conductivity of the object is determined on the basis of the combined solution.
