The invention discloses a liquid cooling structure of a large-current terminal and belongs to the technical field of electric vehicle charging. The large-current terminal comprises two DC charging terminals, an insulation heat conduction support, a heat conduction box, a water inlet pipe and a water outlet pipe, wherein the insulation heat conduction support is arranged between the two DC charging terminals; the heat conduction box is arranged on the insulation heat conduction support between the two DC charging terminals, and a liquid flow channel is arranged in the heat conduction box; the water inlet pipe is arranged on the heat conduction box, and the water inlet pipe is connected with one end of the liquid flow channel; and the water outlet pipe is arranged on the heat conduction box, and the water outlet pipe is connected with the other end of the liquid flow channel. The liquid cooling structure is designed for the charging terminal, and under the working condition of the same terminal in the prior art, the terminal charging current can be greatly improved to improve the charging power, so rapid charging of the charging system is realized. All the components are encapsulated into a whole through the high-heat-conductivity and high-insulation pouring sealant, so heat transfer and safety are greatly improved.
