The invention relates to the technical field of cooling, and provides a cooling system, a ship power device and a control method of the cooling system. The cooling system comprises a cooling mechanism, a resonance tube and an adjusting mechanism, the resonance tube is communicated with the cooling mechanism, and flow noise generated during operation of the cooling mechanism can be transmitted along the resonance tube; a part of the adjusting mechanism is arranged in the resonance tube, and the adjusting mechanism can linearly move along the resonance tube to adjust the resonance frequency of the resonance tube, so that the resonance frequency of the resonance tube is matched with the frequency of the flow noise. According to the cooling system, the resonance tube and the adjusting mechanism are arranged, and the height of the adjusting mechanism in the resonance tube is adjusted according to the frequency of the flow noise, so that the resonance frequency of the resonance tube is matched with the frequency of the flow noise, and the flow noise energy generated during operation of the cooling mechanism is converted into mechanical vibration energy; and then the mechanical vibration can be eliminated through conventional vibration reduction measures, and the noise intensity of the flow noise under different operation working conditions is effectively reduced.

    本发明涉及冷却技术领域,提供一种冷却系统、船舶动力装置及冷却系统的控制方法。上述的冷却系统,包括:冷却机构、共振管和调节机构,共振管与冷却机构连通,冷却机构运行时产生的流噪声能够沿共振管传播;调节机构的部分设置于共振管内,调节机构能够沿共振管直线运动,以调节共振管的共振频率,以使共振管的共振频率与流噪声的频率相匹配。上述的冷却系统,通过设置共振管和调节机构,根据流噪声的频率对共振管内调节机构的高度进行调节,以使共振管的共振频率与流噪声的频率相匹配,从而将冷却机构运行时产生的流噪声能量转变为机械振动能量,之后通过常规的减振措施即可将机械振动消除,有效降低了不同运行工况下流噪声的噪声强度。
