The heat transfer coefficient of convection depends on flow type, on surface temperature distribution, and in transient cases also on time. In so-called conjugated problems, the surface temperature of the wall and flow are coupled together. Thus, the simultaneous solution of convection and conduction in the wall is required. For external and internal flows very accurate analytical expressions have been derived for heat transfer in different kinds of boundary conditions which change according to flow direction. These expressions can be utilized for convection in conjugated problems. In the paper this type of approach is applied for a flat plate, a pile of plates, and a fin. Also the principle of applying analytical solutions and numerical modeling simultaneously for studying a fin array and heat transfer of a mobile phone is given.
