The invention discloses an energy consumption type ship self-flowing cooling system which comprises a seawater cooling subsystem and a power supply and power generation energy consumption subsystem. The power supply and power generation energy consumption subsystem comprises a power supply switch, a frequency converter, a motor generator and a controller; the ship power grid is electrically connected with the cooling water pump sequentially through the power supply switch, the frequency converter and the motor generator. The control end of the controller is electrically connected with the frequency converter and the motor generator so as to control the motor generator to operate in an electric state or a power generation state, and when the motor generator operates in the power generationstate, the energy consumption of the energy consumption circuit is adjusted. According to the energy consumption 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 motor generator generates power to generate resistance through the water turbine principle,and the self-flowing flow is adjusted to the required cooling water amount by controlling the energy consumption circuit and adjusting the rotating speed of the cooling water pump, so the automatic adjustment of the flow of the cooling system is effectively achieved.
