The present invention relates to a life boat, comprising: a hull having a cover portion to cover an upper portion and having an engine room in which an engine for driving a propeller is installed; an external air inlet formed on one side of the cover portion; an engine room intake passage connecting the inside of the hull to the engine room; an engine cooling ventilation passage connected from the engine room to the outside of the hull; and an air suction fan installed in the engine room to rotate by receiving a driving force from a driving shaft of an engine, allowing the air outside the hull to be introduced into the hull through the external air inlet, wherein the air introduced into the hull cools the engine while being introduced into the engine room through the engine room intake passage and then generates an absorption force for discharge to the outside of the hull through the engine cooling ventilation passage.
본 발명은, 상부를 덮도록 덮개부가 형성되고, 프로펠러를 구동하는 엔진이 설치되는 엔진룸이 마련된 선체, 덮개부의 일측에 형성된 외기흡입구, 선체 내부와 엔진룸을 연결하는 엔진룸흡기통로, 엔진룸으로부터 선체 외부로 연결되는 엔진냉각배기통로, 엔진의 구동축으로부터 구동력을 전달받아 회전하도록 엔진룸에 설치하며, 외기흡입구를 통해 선체 외부의 공기가 선체 내부로 유입되게 하고, 선체 내부로 유입된 공기는 엔진룸흡기통로를 통해 엔진룸으로 유입되면서 엔진을 냉각시킨 후, 엔진냉각배기통로를 통해 선체 외부로 배출되게 흡입력을 발생시키는 공기흡입팬을 포함하는 구명정을 제공한다.
