Research on Varying Duty Operation of the Self-circulating Evaporative Inner Cooling System with Composite Structure for High Power Rectifier Equipment

The self-circulating evaporative inner cooling system for high power rectifier equipment has composite structure. In this paper, the arc-length continuation method was chosen. Then the analysis of the minimum parallel unit varying duty operation was achieved, the influence of the main parameters of varying duty has also got. This paper focus on the two parameters: the operating pressure and the inlet subcooling of coolant. This work may instruct the unit to achieve optimal performance, and may provide the theory basis for operation and design of the self-circulating evaporative inner cooling system with composite structure.
