The invention discloses a water-cooled high-voltage shore power supply power unit and an assembling and cooling method thereof. The water-cooled high-voltage shore power supply power unit comprises a water cooling heat dissipation assembly, a power element and a laminated busbar, the water-cooled heat dissipation assembly comprises a water-cooled plate and a heat conduction plate, a plurality of bridge installation grooves are formed in the upper portion of one side of the heat conduction plate, and a busbar installation groove is formed in the lower portion of one side of the heat conduction plate. Through the water-cooled heat dissipation assembly, the heat dissipation effect of a high-voltage shore power supply power unit is improved, heat accumulation is reduced, the service life of a power element is prolonged, the maintenance cost of a heat dissipation air channel of a radiator is reduced, and the use stability of a high-voltage shore power supply is improved by replacing a traditional air-cooled heat d
