Abstract：This paper compares the advantages and disadvantages of closed water cooling systems and open water cooling systems in terms of heat transfer efficiency, footprint, water consumption, and cost. The heat transfer capacity, site environmental conditions, inlet temperature of the phase modulator heat exchanger, and other requirements are taken into account for installing a phase modulator at a certain converter station, as well as the economic investment and operational factors. It is ultimately determined that the external water cooling system for the phase modulator at the converter station adopts an open water cooling scheme. The design scheme of external cooling system for the phase modulator is given in this paper, hoping to provide reference for the selection and design of the external cooling system for phase modulator in subsequent projects.
