Convection heat transfer coefficient is one of the important parameters to solve the heat conduction problem with surface convection heat transfer. In this paper, a new method for determining the convective heat transfer coefficient is proposed. This method is based on the heat transfer in the unsteady thermal solution method of mathematical analysis - lumped parameter analysis based on the design, the specific environment convection heat transfer coefficient determination. This paper comprehensively analyzed the influence of various factors on the accuracy of convection heat transfer coefficient and carried out quantitative analysis. This method is simple and reliable, under normal conditions, the error does not exceed 1.6%.
