Abstract

The invention provides a ship cooling system, The system comprises a cooling device, ship equipment and a heat storage heat exchanger; the cooling device comprises a cooler and a heat exchange loop, the heat exchange loop has a heat exchange inlet and a heat exchange outlet, the heat exchange inlet and the heat exchange outlet are communicated with the cooler; the ship equipment is arranged on the heat exchange loop and located between the heat exchange inlet and the heat exchange outlet; and the heat storage heat exchanger is arranged on the heat exchange loop and is close to the heat exchange outlet. The heat storage heat exchanger absorbs redundant heat when the system is in a high heat load state and discharges the heat when the system is in a low heat load state, so that the temperature fluctuation of cooling water is effectively inhibited, the adverse effect of the high-power fluctuation heat load of a single cooling loop on a central cooling system and other cooling loops can be eliminated, and the cooling efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of ship power systems, in particular to a ship cooling system. Background technique

[0002] The central cooling system is the mainstream development direction of the cooling system of modern marine power plants. Each heating device takes away the heat generated by itself through the first-level fresh water cooling loop, gathers it into the central cooler, and uses the second-level seawater centralized cooling to discharge the heat to the ship. in the outer sea. The central cooling system involves a large number of heating devices, the heat load power varies greatly, and the cooling temperature requirements are different. Therefore, it is necessary to rationally distribute and control the cooling water flow and inlet temperature of each fresh water cooling circuit in a targeted manner.

[0003] In addition, the marine environment where the marine power plant is located is complex and changeable, and its ope...
