Passive outboard cooling system suitable for underwater platform

Abstract

The invention discloses a passive outboard cooling system suitable for an underwater platform, and relates to the field of underwater platform cooling systems. The passive outboard cooling system suitable for the underwater platform comprises a passive heat exchanger and a fresh water circulating pipeline. The passive heat exchanger is arranged outside the board and vertically arranged in the region which is located between a pressure-resistant shell and a light shell. The fresh water circulating pipeline is arranged in a cabin. The passive heat exchanger comprises heat exchange tubes, a firstwater collecting chamber and a second water collecting chamber. The first water collecting chamber and the second water collecting chamber are connected with a water inlet and a water outlet formed in the light shell through connecting pipes correspondingly, and filtering screens are installed in the water inlet and the water outlet. A shell of the passive heat exchanger is connected with a firstcabin penetrating part and a second cabin penetrating part. The fresh water circulating pipeline is formed by a water tank, a fresh water pump, cooling users, valves and pipelines through connection.One end of the fresh water circulating pipeline is connected with the first cabin penetrating part, the other end of the fresh water circulating pipeline is connected with the second cabin penetrating part, and the fresh water circulating pipeline and the passive heat exchanger are combined to form a closed loop. The occupation of the space in the pressure-resistant cabin is reduced, the risk ofleakage of seawater pipelines is avoided, and the system energy consumption and the noise are reduced.

Description

technical field [0001] The invention relates to the field of underwater platform cooling systems, in particular to a passive outboard cooling system suitable for underwater platforms. Background technique [0002] The underwater platform is a complex large system composed of various components, equipment systems or subsystems. It can carry a variety of detection equipment, and can conduct marine scientific research, marine resource exploration and exploitation, and marine observation networks in the deep sea for a long period of time and all-weather. Construction and operation and maintenance tasks. [0003] In order to ensure that the many heating devices on the underwater platform are in good working condition, it is necessary to cool various devices such as power systems, air-conditioning cabinets, and comprehensive purification devices for harmful gases. A common cooling method is to open a sea port on the pressure hull, seawater is introduced into the cabin by a sea wa...

Problems solved by technology

[0004] However, in this cooling method, seawater pumps, intermediate heat exchangers, and seawater pipelines are arranged in the cabin, which takes up a lot of space in the cabin and affects the layout of other equipment, and there is a risk of damage and leakage of seawater pipelines, which will affect personnel and equipment. safety; in addition, the operation noise of the seawater pump and the flow noise of seawater will make the noise of the cooling system higher. energy consumption
