With the continuous innovation of the development technology of infrared imaging detection equipment, strict requirements were put forward for the effective radiation area, stability, uniformity, heating rate and cooling rate of the black body. In order to further improve the key technical parameters of the infrared radiation source, a surface type infrared radiation source based on the Peltier effect was developed.In this paper, the key design processes of the temperature control system which regulated the infrared radiation source were introduced in detail.It included the key design of high-precision temperature acquisition and constant voltage drive of semiconductor devices. Secondly, in the laboratory environment, infrared radiation source with the effective radiation area of 300 mm*300 mm was tested particularly. The results showed that the uniformity of the infrared radiation source could reach （0.05+0.02|Δt|）℃, the heating rate was 8 ℃ / min, the cooling rate was 2 ℃ / min,the stabilization time was five minutes when Temperature rose five degrees,which achieves the expected goal.
