The invention relates to the technical field of lithium battery heat dissipation, in particular to a lithium battery liquid cooling system which comprises a heat convection partition plate, and a first heat dissipation module and a second heat dissipation module are arranged on the two sides of the heat convection partition plate respectively. The first heat dissipation module is provided with a first liquid inlet and outlet connector, the second heat dissipation module is connected with a second liquid inlet and outlet connector, and the first liquid inlet and outlet connector and the second liquid inlet and outlet connector are located at the same end of the heat convection partition plate. The heat convection partition plate is provided with a reversing groove which is communicated with the first heat dissipation module and the second heat dissipation module. Cooling liquid flows into the first heat dissipation module along the first liquid inlet and outlet connecting port, enters the second heat dissipation module through the reversing groove and flows out along the second liquid inlet and outlet connecting port. And the cooling liquid flows in opposite phases in the first heat dissipation module and the second heat dissipation module. The system is simple in structure, good in cooling effect, free of damage to the battery and convenient to install.
