The invention provides a method for designing the size of a water diversion port of a ship self-flowing cooling system. The method comprises the following steps: reading a self-flowing cooling capacity coefficient, a water diversion device additional flow resistance coefficient and a water diversion port size coefficient; inputting weights of a self-flow cooling capacity coefficient and an additional flow resistance coefficient of a water diversion device, and performing weighted summation to obtain a relationship between a weighting coefficient and the water diversion port size coefficient; obtaining the water diversion port size coefficient corresponding to the maximum weighting coefficient, and obtaining the optimal water diversion port diameter according to the water diversion port size coefficient. According to the design method provided by the invention, the water diversion port size coefficient corresponding to the maximum weighting coefficient is determined by reading the relationship among the self-flow cooling capacity coefficient, the additional flow resistance coefficient of the water diversion device and the water diversion port size coefficient, so the optimal water diversion port diameter of the ship self-flowing cooling system is determined according to the known relational expression, a standard design method is provided for the size of a water diversion port of an existing ship self-flowing cooling system, and the design efficiency of the ship self-flowing cooling system is effectively improved.
