| Abstract: |
| Thermoelectric coolers (TEC) can enhance the cooling performance of the radiator but are greatly affected by parameters such as heat dissipation intensity, working current, and working heat-load. In this study, the finite element analysis model of TEC enhanced air-cooling module is established, and the system theory and experimental research on the temperature distribution and operating characteristics of the module are carried out. The study proposes a method to determine the effective operating current, heat load, and cooling coefficient range of TEC enhanced air-cooling module. Simulation and experimental results indicate that there is a limit heat-load Qc,max for a specific TEC enhanced air-cooling module, only when the working heat load Qc
