By adjusting the current of the thermoelectric cooler, the temperature and infrared radiation of temperature-sensing panel could be controlled. A three-dimensional numerical model that couples thermoelectric effect, heat transfer, and fluid flow was set up to predict the transient thermal behavior of the module and was verified through the experiment. Effects of temperature and convective heat transfer coefficient of the ambient medium and current on the module performance were investigated. The results show that the module has good temperature change performance at a higher current of 0-1 A and a lower convection heat transfer coefficient. The low ambient temperature is more conducive to temperature dropping of the module, while the high ambient temperature is more helpful for module's temperature rising. In addition, the temperature and infrared radiation intensity uniformity of the panel were also studied. It is observed that the module presented the well temperature and infrared radiation uniformity over the temperature control progress. Finally, the experiment of changing the infrared radiation of the module was carried out under different backgrounds. The module can achieve a good integration with the background and control infrared radiation as well, which can be well applied to the field of the control of infrared radiation such as infrared camouflage.
