The three-dimensional heat transfer model of a cylinder is established based on the semiconductor refrigeration,in which the influences of the heat source and the external environment on the heat transfer model and the temperature field are considered.By using the variables separation and Laplace transform method,the closed analytical solution of three-dimensional temperature field is derived.The corresponding simulation results are obtained by using the numerical calculation and simulation.The characteristics of temperature field are analyzed.It provides a theoretical basis for the further analysis of three-dimensional temperature field of cylinder and its application.
