The invention relates to a self-centering unmanned ship suitable for adverse sea conditions and a self-centering work manner of the self-centering unmanned ship, and belongs to the field of unmanned ship equipment and techniques. The unmanned ship comprises a main hull, a self-centering deck, equipment, a pipeline mast, a propeller, a radar, an air intake and exhaust system and a host machine system. According to the self-centering unmanned ship disclosed by the invention, the water-tight deck is designed, so that the hull of the unmanned ship has a self-centering function, the possibility of ship overturning of the unmanned ship is avoided, and additionally allocating self-centering equipment is not needed; besides, through the inner structure of the unmanned ship and the self-centering working manner, when a heeling angle of the hull exceeds a certain angle, a host machine and the air intake and exhaust system can be automatically turned off, so that the purpose that the whole ship is in a water-tight condition is realized; and when the heeling angle of the hull is returned to a small angle, the air intake and exhaust system and the host machine are automatically turned on, the mechanism is easy to operate, and the purpose of protecting a propelling system can be realized. During high-speed sailing in deep high sea, the unmanned ship can effectively and continuously work, and the unmanned ship is a reliable, economical and high-efficiency unmanned ship.

The invention relates to a dual-cycle cooling system for an engine. The dual-cycle cooling system comprises a high-temperature circulation cooling system, a low-temperature circulation cooling system and a delay circulation cooling system. The high-temperature circulation cooling system comprises a first expansion water tank, a high-temperature radiator, an engine cooling water jacket, a first water pump, an electronic thermostat, an engine oil cooling device, an electronic supercharger, a turbocharger and a heater. The low-temperature circulation cooling system comprises a second expansion water tank, a low-temperature radiator, a second water pump, an intercooler and a BSG. According to the dual-cycle cooling system, the three sets of circulation cooling systems are arranged, the high-temperature radiator and the low-temperature radiator are arranged, the requirements of different parts to be cooled for the cooling temperatures are met effectively, and the size of the cooling system is not increased by means of the technical scheme.
