The invention relates to the technical field of ship equipment, in particular to a cooling structure. The cooling structure comprises an exhaust pipeline and a cooling shell. The cooling shell coversthe outer wall of the exhaust pipeline, a cooling medium is introduced into a cavity defined by the inner wall of the cooling shell and the outer wall of the exhaust pipeline, a through hole is formedin the pipe wall of the exhaust pipeline, and the two ends of the through hole are communicated with an inner cavity of the exhaust pipeline and the cavity respectively. The cooling structure fully achieves the purpose of water-gas mixing and cooling, and has the advantages of saving energy and reducing consumption. The invention further provides a hull exhaust structure. The hull exhaust structure further comprises a main engine exhaust pipe and a ship board outer plate, and the two ends of the exhaust pipeline are connected with an exhaust port of the main engine exhaust pipe and an exhaustport of the ship board outer plate respectively. According to the hull exhaust structure, the heat dissipation effect in the ship exhaust process is improved, heat energy transmitted to a hull by theexhaust pipeline is reduced, and the problems of paint removal, aging and the like caused by hull heating are avoided.

    本发明涉及船舶设备技术领域,尤其涉及一种冷却结构,包括排气管道和冷却壳体;所述冷却壳体罩设于排气管道的外壁,所述冷却壳体的内壁与所述排气管道的外壁围成的腔室中通有冷却介质,所述排气管道的管壁设有通孔,所述通孔的两端分别与排气管道的内腔和所述腔室连通。所述冷却结构充分达到水气混合降温的目的,且具有节能降耗的优点。本发明还提供一种船体排气结构,还包括主机排气管和船舷外板,所述排气管道的两端分别与主机排气管的排气口和船舷外板的排气口连接。所述船体排气结构提高了船舶排气过程的散热效果,降低排气管道传递给船体的热能,避免船体受热而导致脱漆、老化等问题。
