In this paper, we analysed heat transmission of a flat wall, by two dimensional heat conduction theory, in the case where heat exchange occurs by heat transfer only on one side of its surface. In the theoretical analyses of heat conduction, it is usually assumed that surface heat transfer coefficient is constant. However, in actual cases, it is not constant but a function of position or temperature. In this paper, we obtained general solutions by assuming that it is a function of position, and then, showed an example of calculation by this method in the case where heat transfers to flowing air by laminar surface heat transfer. In this way, it is made clear that surface temperature distribution is remarkably different from the distribution given by an analysis of one dimensional heat conduction, if a wall in thick its thermal conductrvity is better. But there is no remarkable difference between the results obtained by both methods with regard to heat quantity exchanged on the surface.
