Abstract
Background. The problem of increasing the adequacy of the results of thermophysical design and construction, in conditions of the need to ensure a given reliability, does not lose its relevance. The conducted research is aimed at increasing the adequacy of the results of the thermophysical design of electronic equipment by increasing the completeness of the thermophysical parameters of heat-dissipating elements by improving the methods of thermophysical design of electronic means. To do this, it is necessary to solve the problem of developing a thermophysical design algorithm taking into account the actual thermal resistance of the heat sink element. Materials and methods. Based on the methodological basis of the thermophysical design of radioelectronic devices, an algorithm for thermophysical design based on measuring the value of thermal resistance is proposed. The latter is a universal characteristic of electronic equipment heat sinks, which combines such parameters of cooling systems as the effective area and thermal conductivity of the material. Results. The algorithm proposed in the work, when applied at the stages of thermophysical design, makes it possible to take into account the actual value of the thermal resistance of heat sinks and thereby increase the completeness of data on the thermophysical parameters of heat sink elements of electronic equipment and electronic means.
