THERMALLY CONDUCTIVE INCLUSIONS AFFECTING THE ANALYSIS OF REDUCED THERMAL WALL RESISTANCE

Abstract

The paper presents the main concepts of the analysis of reduced thermal resistance taking into account flat, linear and point-like conductive inclusions. The paper gives a comparative analysis of the calculation results of educed thermal resistance and the construction of two- and three-dimensional temperature fields. The analysis of calculating results on the reduced thermal resistance shows that the construction of two-dimensional fields gives rather an underestimated picture of the temperature distribution and the reduced thermal resistance. Three-dimensional fields describe the actual size of thermally conductive inclusions and provide the most complete picture of the temperature field distribution and reduced thermal resistance. Thermally conductive inclusions should be taken into account in the analysis of reduced resistance which is acquired by the construction of three-dimensional temperature fields.
