Abstract

The invention relates to the technical field of marine equipment, and provides a power equipment shell side cooling heat exchange system which comprises an in-cabin power equipment cooling pipeline, aheat exchanger and a jet device. The heat exchanger is arranged between the ship body and the outer ship plate and comprises an upper end socket, a lower end socket, a heat exchange pipe and an outershell, a heat exchange cavity is formed between the outer shell and the ship body, the heat exchange pipe is located in the heat exchange cavity, the heat exchange cavity and the heat exchange pipe are vertically arranged, and the heat exchange pipe communicates with the upper end socket and the lower end socket. A water inlet and a water outlet which are respectively communicated with the heat exchange cavity are formed in the outer shell; a seawater inlet and a seawater outlet are formed in the outer ship plate; the jet device is located at the water outlet and connected with the cabin medium-pressure air system and jets medium-pressure air towards the seawater outlet. The power equipment shell side cooling heat exchange system can cool the power equipment in the cabin, forced convection heat exchange 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 a shell-side cooling heat exchange system for 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. Contents of the invention [0003] An embodiment of the present invention prov...
