The ship engine compartment cooling system comprises an engine compartment and an internal combustion engine shell, a water diversion device is arranged at one end of the engine compartment, a self-lifting fixed-point cooling device is arranged at the bottom of the engine compartment, a fresh water cooling device is arranged at the top of the engine compartment, and negative suction air flow cooling devices are symmetrically arranged on the side walls of the engine compartment. The water diversion device comprises a water storage tank, a water diversion pipe, a pressure pipe and a pressure control component arranged on the upper surface of the ship body. The self-lifting fixed-point cooling device comprises a labyrinth water box, a plurality of heat guiding components arranged on the outer wall of the internal combustion engine shell and a self-lifting water diversion component arranged at the bottom of the inner wall of the power cabin. The negative suction airflow cooling device comprises a transmission pipeline, a flow control component arranged on the outer wall of the transmission pipeline, a heat conduction component with one end penetrating through the outer wall of the transmission pipeline and the other end extending into the power cabin, and a negative suction airflow component arranged at the end of the heat conduction component. According to the cooling system, the engine compartment can be cooled quickly and conveniently, and anti-leakage protection can be conducted on the engine compartment conveniently.
Description
technical field [0001] The invention mainly relates to the technical field of cooling systems, in particular to a cooling system for a ship's power cabin that uses seawater to cool down. Background technique [0002] The internal combustion engine in the ship's power cabin generates a lot of heat when it is working. However, the power cabin is small and poorly ventilated. The heat generated by the internal combustion engine is often not discharged in time. Overheating of the ship's power cabin will affect the ship's power system. [0003] According to the cooling system of a ship engine room provided by the patent document with the application number CN201920203626.0, it can be known that the system includes a seawater desalination machine, an expansion tank, a diesel engine and a first cooler connected in sequence through pipelines, and the connection between the expansion tank and the diesel engine A first high-pressure pump is arranged between them, the first cooler is co...
