This paper mainly describes a design of the constant temperature control system for phase and magnitude stabilization system in heavy iron accelerator. Firstly, the composition and operating principle of the constant temperature control sub-system are introduced. And then, the design of circuit and relative components selection are introduced, including thermal electronic cooler selection, temperature sensor selection and core control chip selection, and fan detection and control circuit design and relative components selection, current and voltage detection Circuit design and relative components selection as well as power amplifier circuit design. Finally, the testing results of the constant temperature control sub-system is presented and analyzed.
