Description

technical field [0001] The invention relates to a circulating water cooling system and a water cooling method for heat dissipation of a high-voltage shore power supply. Background technique [0002] High-voltage shore power supply equipment is widely used in various docks. Due to the complex environment of high-voltage shore power supply, in order to facilitate use and reduce infrastructure, container-type high-voltage shore power supply has more advantages. The existing high-voltage shore power supply is a fan inside the container. For heat dissipation, the air humidity of the seaside, riverside, and wharfs is high, and the air in some places contains salt spray. The air with high humidity and salt spray is sucked into the high-voltage shore power supply by the fan, which may cause corrosion of the internal components of the high-voltage shore power supply equipment. The service life of the high-voltage shore power supply is reduced, and the maintenance cost is increased. ...

[0002] High-voltage shore power supply equipment is widely used in various docks. Due to the complex environment of high-voltage shore power supply, in order to facilitate use and reduce infrastructure, container-type high-voltage shore power supply has more advantages. The existing high-voltage shore power supply is a fan inside the container. For heat dissipation, the air humidity of the seaside, riverside, and wharfs is high, and the air in some places contains salt spray. The air with high humidity and salt spray is sucked into the high-voltage shore power supply by the fan, which may cause corrosion of the internal components of the high-voltage shore power supply equipment. Reduced service life of high-voltage shore power supply and increased maintenance costs

[0003] Coal wharves with a lot of dust may cause serious dust accumulation inside the high-voltage shore power supply equipment, resulting in blockage of the cooling air duct of the high-voltage shore power supply, over-temperature faults, and short-circuit faults. Dust containing metal powder may directly cause internal damage to the high-voltage shore power supply. Components are damaged by short-circuit, and metal dust reduces the insulation of high-voltage shore power supply, which may cause damage to shore power supply failure. Therefore, the existing air-cooled heat dissipation method is changed to solve the above problems
