Embodiment Construction

[0030] The heat in the engine room is mainly concentrated in the top area of ​​the engine room and the heating equipment area at the bottom of each platform in the engine room. The heat in the engine room is absorbed by the high-efficiency phase change material, and the heat is transferred to the open space outside the hull and the bottom wall of the engine room in contact with seawater through heat pipe transfer. The flow chart of the system is as follows: figure 1 shown.

[0031] In the marine phase change engine room energy absorption system, the paraffin-aluminum foam mixture with a phase transition temperature of 30-35°C was selected as the medium. Good reversibility and high efficiency of solid-solid conversion are beneficial to packaging. We design the phase change material into products, fill the phase change material in the metal shell, and the shell is equipped with different numbers of enhanced heat transfer ribs. The heating equipment area at the bottom of the shi...

Abstract

The invention relates to a boat machine cabin phase change energy absorption system. In a boat machine cabin upper space with concentrated heat, an energy absorption device using a phase change material is used for communicating with a boat outside open air space; a boat machine cabin bottom heating equipment region communicates with the machine cabin bottom wall surface, in contact with the sea water, of the energy absorption device using the phase change material. The energy absorption device is provided with a metal casing; the phase change material is filled in the metal casing; the energy absorption device is also provided with a heat pipe; one end in the metal casing is a heat pipe evaporation end; one end outside the metal casing is a heat pipe condensing end; the energy absorption device is also provided with a plurality of reinforced heat transfer rib sheets to be fixedly connected with the surface of the metal casing. The phase change material is a mixture of paraffin-foam aluminum with the phase change temperature being 30 to 35 DEG C.

Description

technical field [0001] The invention belongs to the technical field of marine equipment, in particular to a phase-change energy-absorbing system for a marine engine room. Background technique [0002] In existing ships, especially large ships, the engine room is the central area of ​​the ship's power and electricity, and it includes numerous machinery, electricity, and control equipment. Diesel engines, auxiliary boilers and other mechanical equipment not only need a lot of fresh air during normal operation, but also release a lot of heat to the surrounding environment; generators, motors and electrical control equipment also release a certain amount of energy to the surrounding environment during work; there are many heating in the engine room. Tanks, steam pipelines, etc. also release heat to the environment in the cabin, which will significantly increase the temperature in the cabin, affecting the comfort of the crew when they work, which is not conducive to the crew's wo...
