The invention relates to the technical field of marine equipment, and provides an outboard cooling heat exchange system for ship power equipment, which comprises an in-cabin power equipment cooling pipeline, a heat exchanger and a jet device. The in-cabin power equipment cooling pipeline is used for cooling the power equipment in the cabin; the heat exchanger is arranged between the ship body andthe outer ship plate and comprises a heat exchange pipe and an outer shell, a cooling cavity is formed between the outer shell and the ship body, the heat exchange pipe is located in the cooling cavity, the cooling cavity and the heat exchange pipe are transversely arranged, the heat exchange pipe is communicated with a power equipment cooling pipeline in the cabin, and a water inlet and a water outlet which are communicated with the cooling cavity are formed in the outer shell. The jet device is connected with the in-cabin medium-pressure air system and used for adjusting the seawater replacement speed in the cooling cavity by jetting medium-pressure air. The outboard cooling heat exchange system for the ship power equipment can cool the power equipment in a cabin, forced convection heatexchange between the heat exchanger and seawater is achieved, the heat exchange efficiency is improved, and the heat exchange capacity can be adjusted.
Description
technical field [0001] The invention relates to the technical field of marine equipment, in particular to an outboard cooling heat exchange system for marine power equipment. Background technique [0002] At present, the outboard coolers of ships are generally arranged at the seabed door. The outboard seawater enters the cooler box through the bottom grille, and after heat exchange with the heat medium in the outboard cooler, it rises to the height of the cooler box due to the decrease in density. The grill escapes. The existing form of heat exchange between the outboard cooler and seawater is natural convection, the heat transfer efficiency is low, and there is only one grille between the seawater and the outboard cooler, and the outboard cooler is easily blocked by pollutants, making it heat exchange The capacity decreased, resulting in an overheating accident of the cooled equipment in the cabin.
