本发明涉及船舶冷却器技术领域,并提供一种自封堵共形冷却器及船体,该冷却器包括换热管,换热管内的轴向两端分别设有自动封堵结构;自动封堵结构包括撑座和堵块,撑座绕设于换热管内壁,撑座开设有流道,堵块设于流道内并通过弹性连接件与撑座连接,堵块在受力增大的状态下移动至与撑座接触以将流道的一端封堵。本发明内嵌式的自动封堵结构,在堵块与撑座之间形成换热介质的流道,当换热管发生冲击破口海水进入换热管内部时,换热管内部压力增大,堵块在压力增大作用下向撑座移动,堵块移动至与撑座贴合以将流道封堵,实现换热管的自动封堵,避免海水混入管侧工质,有效保证了换热系统的正常运行,保障了船舶和船员的安全。
The invention relates to the technical field of ship coolers, and provides a self-plugging conformal cooler and a ship hull, the cooler comprises a heat exchange tube, and automatic plugging structures are arranged at the two axial ends in the heat exchange tube respectively; the automatic plugging structure comprises a supporting seat and a plugging block, the supporting seat is wound on the inner wall of the heat exchange tube, a flow channel is formed in the supporting seat, the plugging block is arranged in the flow channel and connected with the supporting seat through an elastic connecting piece, and the plugging block moves to make contact with the supporting seat in the state that stress is increased so as to plug one end of the flow channel. According to the embedded automatic plugging structure, the flow channel of the heat exchange medium is formed between the plugging block and the supporting seat, when the heat exchange pipe is impacted to break and seawater enters the heat exchange pipe, the internal pressure of the heat exchange pipe is increased, the plugging block moves towards the supporting seat under the action of pressure increase, and the plugging block moves to be attached to the supporting seat so as to plug the flow channel; automatic plugging of the heat exchange pipe is achieved, seawater is prevented from being mixed into a working medium on the pipe side, normal operation of a heat exchange system is effectively guaranteed, and safety of ships and sailors is guaranteed.
