The invention relates to the technical field of marine environment observation, in particular to a cooling and ventilating device for a semi-submersible navigation body. According to the technical scheme, in the advancing process of a navigation body, seawater is drained through a seawater drainage pipe and flows into a heat exchange pipe through a seawater inlet flange. Waste gas of the diesel engine enters the middle of the integrated heat exchanger through the gas inlet flange. In the flowing process, the waste gas makes contact with the heat exchange pipe and is cooled by seawater flowing in the pipe, and meanwhile the waste gas makes contact with the navigation body shell and is cooled by seawater flowing outside the navigation body shell. After flowing out of the heat exchange pipe, the seawater upwards flows into the seawater discharge pipe and is discharged into the seawater outside the navigation body shell. Seawater is introduced into the heat exchanger through the positive pressure area and the negative pressure area generated by seawater flowing, diesel engine waste gas is discharged out of the cabin after being cooled, waste gas condensate water is automatically treated, and the economical efficiency and maintainability of equipment are improved.
本发明涉及海洋环境观测技术领域,特别涉及一种半潜式航行体用冷却通气装置。一种水下无源舱段一体式冷却通气装置,其技术方案是:航行体前进的过程中,海水经海水引流管引流通过海水入口法兰流入热交换管。柴油机的废气通过进气法兰,进入一体式换热器中部;废气在流动的过程中,与热交换管接触,被管内流动的海水冷却,同时,废气与航行体外壳接触,被航行体外壳外流动的海水冷却。海水从热交换管流出后,向上流入海水排出管,排出到航行体外壳外的海水中。本发明利用海水流动产生的正压区和负压区来将海水引入换热器,柴油机废气冷却后排出舱外,废气冷凝水也得到自动处理,提高了装备的经济型,维护性。
