An embodiment of the present invention provides a marine diesel power system, including: a diesel engine, a conformal heat exchanger, and a jet flow device, wherein the first inlet and the first outlet of the conformal heat exchanger are respectively connected to the diesel engine; the conformal heat exchanger The second inlet is used to flow in seawater, and the second outlet is used to discharge seawater; wherein, the heat exchange tube of the conformal heat exchanger is arranged perpendicular to the direction of seawater flow; the jet device is arranged on the conformal heat exchanger At the second outlet, the first inlet of the jet fluidic device is used to inhale the seawater discharged from the second outlet of the conformal heat exchanger, the second inlet of the jet fluidic device is connected to the diesel engine exhaust pipe of the diesel engine, and the outlet of the jet fluidic device is used to discharge Sea water and exhaust from diesel engine exhaust pipes. In the marine diesel power system provided by the embodiment of the present invention, by setting a jet device at the second outlet of the conformal heat exchanger, under the action of turbulent diffusion, the heat transfer form of the conformal heat exchanger is changed to forced convection heat transfer , improving the heat transfer efficiency.
Description
technical field [0001] The invention relates to the technical field of ship outboard cooling, in particular to a ship diesel power system. 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 exchanges heat with the heat medium in the outboard cooler. After the heat exchange, the seawater is heated, and its density decreases and rises to Escape from the grille above the cooler box. The existing form of heat exchange between the outboard cooler and seawater is natural convection, and 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 transfer The capacity decreased, resulting in an overheating accident of the cooled equipment in the cabin. Contents of the invention [0003] An embodiment of the present inven...
