The invention discloses an energy storage type ship self-flowing cooling system which comprises a seawater cooling subsystem and a power supply and power generation energy storage subsystem. The energy storage subsystem comprises a power supply switch, an energy storage circuit, a frequency converter and a controller; the cooling water pump has an electric state and a power generation state; the energy storage circuit is electrically connected with the output end of the frequency converter; the ship power grid is electrically connected with the cooling water pump sequentially through the powersupply switch and the frequency converter. The control end of the controller is electrically connected with the frequency converter and the cooling water pump so as to control the cooling water pumpto operate in an electric state or a power generation state, and the charging power of the energy storage circuit is adjusted in the power generation state. According to the energy storage type ship self-flowing cooling system, in the pump flow state, the rotating speed and flow of the water pump are directly adjusted through the frequency converter; in the self-flowing state, the water turbine principle is used for power generation and energy storage, and the rotating speed of the cooling water pump is controlled by controlling the charging power, so the self-flowing flow is adjusted to the required cooling water amount, and automatic adjustment of the flow of the cooling system is effectively achieved.
