The present invention relates to a heat exchange system for a vessel engine. According to the present invention, the heat exchange system for a vessel engine reuses sucked air of a high temperature/a high pressure, discharged into the air when a combustion pressure of a combustion chamber becomes abnormally high as air density sucked to an engine becomes high due to a low atmosphere temperature when a vessel sails in polar regions. The heat exchange system for a vessel engine includes: a blow-off valve installed in an outlet of a compressor of a turbocharger and opened when the pressure of the sucked air to the engine is equal to or higher than a predetermined value; a vortex tube dividing the sucked air passing through the blow-off valve into low-temperature air in which the temperature is relatively lower than that of the sucked air and high-temperature air in which the temperature is relatively higher than that of the low-temperature air, by vortex (spiral rotation); an intake chamber storing the low-temperature air separated from the vortex tube; and a discharge chamber storing the high-temperature air separated from the vortex tube. Therefore, the heat exchange system for a vessel engine can improve energy reducing efficiency of the vessel by transferring the sucked air of the high temperature and the high pressure, discharged into the air by the blow-off valve, to the inlet of the turbocharger, a front end of an SCR catalyst, and heating of the vessel.

    본 발명의 선박 엔진용 열교환 시스템은, 선박의 극지방 운항시에 낮은 대기온도로 인하여 엔진으로 흡입되는 공기 밀도가 높아져 연소실의 연소압력이 비정상적으로 높아질 때에 대기중으로 배출되는 고온/고압의 흡입공기를 재사용하는 선박 엔진용 열교환 시스템에 있어서, 터보차저의 압축기 출구에 설치되어 엔진으로의 흡입공기가 압력이 설정치 이상일 때에 개방되는 블로우 오프 밸브; 상기 블로우 오프 밸브를 통과한 흡입공기를 와류(나선형 회전운동)에 의해 흡입공기보다 상대적으로 저온인 저온공기와 상기 저온공기보다 상대적으로 고온인 고온공기로 분리하는 볼텍스 튜브; 상기 볼텍스 튜브에서 분리된 저온공기가 저장되는 흡기챔버; 및 상기 볼텍스 튜브에서 분리된 고온공기가 저장되는 배기챔버;를 포함하는 것을 특징으로 한다. 이에 따라, 블로우 오프 밸브에 의해 대기중으로 배출되는 고온 고압의 흡입공기를 선박의 난방, SCR 촉매 전단, 터보차저의 입구로 전달하여 선박의 에너지 절감효율을 높일 수 있는 효과가 있다.
