Abstract
The pulse forming network (PFN) is an important component of the electromagnetic launch system, and its continuous discharge performance at same frequency is of great significance for the development of electromagnetic launch system. Pulse inductor is one of the key components of PFN, which has a decisive influence on the amplitude, pulse width and wave front time of discharge current. In order to study the thermal management scheme that could meet the temperature control requirements of pulse inductors under continuous discharge condition, an electromagnetic-thermal-fluid coupling model is established, and the temperature change of pulse inductor under the condition of liquid cooling and natural cooling is analyzed. It is concluded that the natural cooling scheme cannot meet the temperature control requirements, while the liquid cooling scheme can meet it. But the disadvantage of the liquid cooling scheme is that the maximum temperature difference inside the inductor will be increased.
