Abstract
An understanding of the mechanisms of heat transferis becoming increasingly important in today’s world. Conduction and convection heat transfer phenomena are found throughout virtually all of the physical world and the industrial domain. These two phenomena are very complicated and subjects to all bodies. To simplify their modeling for better understand of heat transfer, an analogy between thermal and electrical circuits are established. Assuming steady-state, one-dimensional heat transfer via conduction and/or convection modes, expressions are derived for thermal resistances across planar, cylindrical and spherical interfaces. Series, parallel and combination of series-parallel thermal network models are discussed (emphasizing similarity to electrical circuit theory). The equivalent thermal resistances are calculated for all thermal networks.
