The invention relates to the technical field of ship manufacturing. The ship power system with the cooling and noise reduction functions comprises a containing tool and a ship power device. The containing tool comprises an external anti-collision frame and an internal cooling and noise reduction function frame. A non-totally-closed containing cavity is formed in the external anti-collision frame and used for containing the internal cooling and noise reduction function frame. The built-in cooling and noise reduction function frame is formed by a top plate, a bottom plate, two side plates and two heat dissipation fences in a surrounding mode. And air inlet structures are arranged on the top plate, the bottom plate and the side plates. The heat dissipation fence is formed by arranging a plurality of rectification noise reduction pieces. In the working state, peripheral cold air enters through the air inlet structure and directly blows the ship power device, then part of the cold air passes through the rectification and noise reduction piece to be directly discharged, the rest of the cold air is directly blown towards the rectification and noise reduction piece, after rectification, swirling flow mixing is carried out, then the cold air is blown towards the ship power device again, and meanwhile the ship power device is directly discharged. Part of the working noise passes through the rectification noise reduction piece to be directly spread outwards, and the rest of the working noise is folded back due to being blocked.
本发明涉及船舶制造技术领域。兼具降温和减噪功能的船舶动力系统包括容置工装和船舶动力装置。容置工装包括外置防撞击框和内置降温减噪功能框。在外置防撞击框的内部形成有非全封闭态容纳腔,以用来置入内置降温减噪功能框。内置降温减噪功能框由顶板、底板、两侧板和两散热栏柵围拢而成。在顶板、底板和侧板上均设有进气结构。散热栏柵由多个整流减噪件排列而成。工作状态下,外围冷空气经由进气结构进入,直吹船舶动力装置,而后,部分冷空气绕经整流减噪件以直接外排,而剩余部分向着整流减噪件进行直吹,经整流后,发生回旋混流后再次吹向船舶动力装置,与此同时,部分工作噪音绕经整流减噪件得以直接向外传播,而剩余部分因受到阻挡而折返。
