The embodiment of the invention provides a method and a device for improving the performance of a self-flowing cooling system, and a control unit. The method comprises the steps of reading the relation between a cooling capacity coefficient and an additional resistance coefficient and the angle of an outlet grille of a water diversion device; inputting weights of the cooling capacity coefficient and the additional resistance coefficient, and summing to obtain a relation between the weighting capacity coefficient and the angles of the other outlet grids of the water diversion device; and when the weighting capability coefficient is maximum, obtaining the corresponding outlet grid angle of the water diversion device. According to the method for improving the performance of the self-flow cooling system, the outlet grid angle of the water diversion device corresponding to the maximum weighting capacity coefficient is used as the optimal outlet grid angle of the water diversion device of the self-flow cooling system under the current navigational speed working condition, so that the self-flow cooling system obtains the optimal comprehensive performance under the current navigational speed working condition; and moreover, by adjusting the angle of the outlet grid of the water diversion device under different navigational speed working conditions, the defect that the performance of anexisting self-flowing cooling system is difficult to adapt to the requirements of different navigational speed working conditions after design is completed is effectively overcome.
