The invention relates to the technical field of cooling, and provides a cooling system and a ship power device. The cooling system comprises a cooling mechanism, a resonance mechanism, a detection mechanism and an adjusting mechanism, the resonance mechanism is communicated with the cooling mechanism, the resonance mechanism is provided with a cavity, the cavity is filled with gas, the detection mechanism is used for detecting the frequency of flow noise generated when the cooling mechanism operates, and the adjusting mechanism is used for adjusting the flow noise. The adjusting mechanism is used for adjusting the volume of the gas in the cavity based on the frequency of the flow noise so that the resonant frequency of the cavity can be matched with the frequency of the flow noise. According to the cooling system, the air volume in the cavity of the resonance mechanism is adjusted according to the frequency of the flow noise, so that the resonance frequency of the cavity of the resonance mechanism 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,提供一种冷却系统及船舶动力装置。上述的冷却系统,包括:冷却机构、共振机构、检测机构和调节机构,共振机构与冷却机构连通,共振机构具有腔体,腔体内填充有气体,检测机构用于检测冷却机构运行时产生的流噪声的频率,调节机构用于基于流噪声的频率调节腔体内气体的体积,以使腔体的共振频率与流噪声的频率相匹配。上述的冷却系统,根据流噪声的频率对共振机构腔体内空气体积进行调节,以使共振机构腔体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。
