Embodiment Construction

[0018] as attached figure 2 As shown, according to the actual calorific value of the ship system, the outboard seawater temperature is 32°C and the ship speed is 5m / s. The required heat exchange area of ​​the hull; water and nanofluids and other low-boiling point fluids are selected as the working medium 10, and the amount of the required working medium 10 is calculated according to the heat transfer. The evaporative heat exchanger 1; the surface of the high-efficiency evaporative heat exchanger 1 in contact with the working medium 10 is processed into a hydrophilic surface with a capillary microstructure, and the inner surface of the hull 9 used for heat exchange is processed into a superhydrophobic surface with a microstructure . Make full use of the ship's double bottom and side chords, select materials with poor thermal conductivity as the heat insulation cover plate 13, place the working fluid 10 and the high-efficiency evaporative heat exchanger 1 at the bottom of the ...

Abstract

The invention relates to a self-cooling method and system which are used for a ship and other water navigation articles. According to the method, the sea water pump is omitted, based on the efficient phase-change heat transfer basic principle, efficient phase change heat transfer of fine film evaporation, strengthened heat transfer of pulse flow, condensation strengthened heat transfer on an efficient self-cleaning surface and other strengthened heat transfer methods are used sufficiently and combined to build an efficient heat exchanging channel between a ship shell and a waste heat source, waste heat generated by the system is rapidly transferred to part of the ship shell through the efficient heat exchanging channel, along with navigation of the ship in water, the waste heat is automatically dissipated to the navigation environment through the shell. The self-cooling method has the remarkable advantages that energy consumption is low, noise is small, equipment does not make direct contact with sea water and is convenient to maintain and manage daily, and bottom fouling of the ship can be restrained to a certain degree.

Description

technical field [0001] The invention relates to a ship self-cooling method, that is, to cancel the marine sea water pump, make full use of the huge cold source of the ship shell, and transfer the waste heat generated by the equipment on the ship to the ship shell through the high-efficiency heat transfer channel. The ship sails in the water, and the waste heat will eventually be lost to the sailing environment through the hull. It is mainly used on all kinds of ships, warships, submarines and other underwater navigation objects. Background technique [0002] About 30% of the heat released during the combustion process of a diesel engine will be dissipated to the outside world through cylinders, cylinder heads, pistons and other components. In addition to the large amount of waste heat generated by the main diesel engine on board, other auxiliary equipment also produces a lot of waste heat during the working process. In order to dissipate this heat and ensure that various eq...
