Self-flowing cooling system and ship

Abstract

An embodiment of the invention provides a self-flow cooling system and a ship. The self-flowing cooling system comprises a cooler and a phase change water tank, two ends of the cooler and two ends ofthe phase change water tank respectively communicate with a self-flowing water inlet and a self-flowing water outlet, and the cooler communicates with a user heat source to form a first cooling loop;the phase change water tank communicates with the user heat source to form a second cooling loop; a first valve is arranged on a pipeline for communicating the phase change water tank with the user heat source; and a second valve is arranged on a communicating pipeline between the phase change water tank and the self-flowing water inlet. According to the ship self-flowing cooling system and the ship, supply and demand balance of cooling water is achieved by arranging a cooling water tank, it is guaranteed that the outlet temperature of the user heat source fluctuates within the target value range, and thermal shock generated when the heat exhaust amount of the user heat source is suddenly increased is avoided. The stability of the self-flowing cooling system is improved, and normal operation of a ship power system is facilitated.

Description

technical field [0001] The invention relates to the technical field of ship cooling systems, in particular to an artesian cooling system and ships. Background technique [0002] The ship cooling system is an important link to ensure the safe and reliable operation of the ship's power plant. Most of the heat generated by the ship's power system such as diesel engine or steam power system and auxiliary equipment needs to be transferred to the cooling water through the ship's cooling system and discharged out of the ship. [0003] With the development of large-scale advanced ships, the amount of cooling water required by ships continues to increase. Ship cooling water pumps are one of the main energy-consuming components of ship power systems. The high energy consumption and noise are not conducive to the development of green ships. In order to reduce the power consumption and noise of the cooling water pump, some modern green ships and high-speed ships use a self-flowing cooli...
