| Abstract: |
| Thermo-electric cooler (TEC) has been more and more widely used in aerospace, electronic industry and etc, for its merits which mechanical refrigeration lacks, such as small volume, high working speed and no noise. In this paper, the stationary temperature field analytical solution of TEC based on the heat transfer characteristics of TEC is derived. The differential equation of transient nonlinear temperature field analysis for TEC structure is also established. By deriving the finite element equation of TEC structure’s thermal analysis with Galerkin method and solving the finite element equation of the nonlinear thermal analysis, both the steady temperature field and the transient temperature field are obtained. The numerical results show that the presented finite element model for TEC structure’s nonlinear thermal analysis has a high precision and efficiency in analyzing the nonlinear temperature field of TEC. |
