Description

Technical Field

[0001] This application relates to the field of underwater electronic equipment technology, and in particular to a high-pressure-resistant, strongly sealed electronic compartment with liquid cooling supply capability. Background Technology

[0002] With increasing exploration and utilization of the ocean, deep-sea equipment has flourished in recent years. Deep-sea electronic cabins, which serve as carriers for deep-sea equipment, are able to operate independently and stably in the deep-sea environment, and their use is increasing. However, they also face more and more problems and shortcomings.

[0003] 1) The electronic compartment is limited by the size and space of the submarine platform on which it is mounted, and its own capacity is relatively small. It is necessary to consider how to make efficient use of the space inside the electronic compartment and meet the needs of electronic equipment maintainability.

[0004] 2) As the functions of deep-sea equipment become more and more powerful, the heat generated by the equipment itself is increasing. It is necessary to consider how to significantly improve the immersion heat dissipation capability of the electronic cabin in the deep-sea environment.

[0005] 3) Some deep-sea equipment requires liquid cooling for heat dissipation. However, the commonly used liquid cooling sources are not suitable for the deep-sea environment and are too large and heavy. They are not suitable for direct installation in submersible platforms or electronic compartments that have strict requirements on size and weight. It is necessary to consider how to deeply integrate the liquid cooling source with the electronic compartment so that the electronic compartment has a certain liquid cooling supply capacity.

[0006] 4) As the diving depth increases, the pressure resistance requirements of the electronic compartment become higher and higher. At the same time, the deformation of the submersible will increase with the diving depth, which further increases the difficulty of sealing the electronic compartment. Utility Model Content

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0033] This application provides a high-pressure-resistant, tightly sealed electronic compartment with liquid-cooled supply capability, such as... Figure 1 , Figure 2 As shown, it includes:

[0034] The cabin 1 includes a cabin frame 101, has a housing space, and is closed by an electronic cabin cover 2. A liquid cooling supply unit is installed in the housing space.

[0035] The liquid-cooled supply unit 3 includes a water pump 301, an internal pipeline 302, a heat exchange plate 303, and a sensor 304. The water pump 301 is connected to the internal pipeline 302, the internal pipeline 302 is connected to the heat exchange plate 303, and the sensor 304 is installed on the internal pipeline 302 for monitoring and collecting relevant parameter information. The liquid-cooled supply unit 3 supplies liquid-cooled liquid through the supply pipeline 5 and the return pipeline 6 provided on the cabin 1.

[0036] Electronic compartment cover 2, cover sealing port 201, cover sealing boss 202, cover curved cover body 206, the cover curved cover body 206 is installed on the end of the compartment 1 and connected to the cover sealing boss 202 to seal the cover sealing port 201.

[0037] The hull mounting interface 107 is used to install the electronic compartment to the target equipment.

[0038] In a specific example, the hull mounting interface 107 on the electronic compartment hull 1 is installed onto the submersible platform. Liquid cooling supply capability is formed through the liquid cooling supply unit 3 integrated inside the hull 1, and liquid is supplied to the equipment requiring liquid cooling through the liquid supply pipe 5 and return pipe 6 on the outside of the electronic compartment hull 1. The liquid supply capability is determined to meet the requirements by the temperature and flow rate sensors 304 inside the liquid cooling supply unit 3.

[0039] The connector assembly 4 on the outside of the hull 1 communicates with and manages the power supply to the submersible platform. The pressurization and pressure monitoring inside the electronic compartment are carried out through the pressurization valve 9 on the upper part of the electronic compartment hull 1. Before each electronic compartment is installed and launched, the pressure inside the compartment is increased by the pressurization valve, and the pressure holding condition of the electronic compartment is observed to determine its pressure resistance and sealing performance.

[0040] The sealed electronic compartment of this application embodiment can meet the requirements of efficient space utilization integration and maintainability, has good immersion heat dissipation capability, can withstand ultra-high pressure in the deep sea and has good sealing.

[0041] In some embodiments, the cabin 1 is further provided with an internal horizontal reinforcing plate 102 and an internal vertical reinforcing plate 103 to structurally strengthen the accommodating space based on the internal horizontal reinforcing plate 102 and internal vertical reinforcing plate 103. Other functional modules can be installed on the reinforcing plates, which helps to improve the space utilization of the electronic cabin and, more importantly, can enhance the cabin frame 101 of the cabin 1 by providing internal support and improving the rigidity of the cabin 1. The cabin frame 101 is designed with dense external annular reinforcing ribs 105 and external transverse reinforcing ribs 106, which can further greatly improve the rigidity and immersion heat dissipation area of ​​the electronic cabin 1.

[0042] In some embodiments, the cabin 1 is made of 7-series aluminum alloy. 7-series aluminum alloy has good overall thermal conductivity and compressive strength, is lightweight, and is easy to process and form as a whole, without internal defects caused by welds or casting that affect strength. Furthermore, the edges of the cabin frame 101 can be chamfered with a certain radius to reduce the pressure on each surface of the cabin.

[0043] In some embodiments, such as Figure 3 As shown, an end face sealing ring 7 and a radial sealing ring 8 are provided between the cabin body 1 and the electronic cabin cover 2 for sealing. In some embodiments, the portion of the electronic cabin cover 2 that contacts the cover sealing port 201 is coated with a composite material coating 203.

[0044] Specifically, electronic compartment covers 2 are installed at both ends of the compartment 1. The electronic compartment 1 and the electronic compartment covers 2 are sealed together by a dense array of cover mounting bolts 205. Cover sealing bosses 202 are inserted into the compartment mounting interface 107, and radial sealing between the electronic compartment 1 and the electronic compartment covers 2 is achieved through radial sealing rings 8 installed on radial sealing grooves 204. Cover sealing ports 201 are attached to the compartment sealing ports 104, and end-face sealing between the electronic compartment 1 and the electronic compartment covers 2 is achieved through end-face sealing rings 7 installed on end-face sealing grooves 108. The cover sealing ports 201 are coated with a composite material coating 203, which improves the microscopic contact rate and hydrophobicity between the end faces, greatly enhancing the end-face sealing capability.

[0045] In some embodiments, the liquid cooling supply unit 3 further includes an expansion tank 306, a leakage detector 307, and an in-chamber temperature sensor 308, wherein the expansion tank 306;

[0046] Specifically, the heat exchange plate 303 of the liquid-cooled supply unit 3 is installed at the bottom of the inner cavity of the compartment 1, ensuring good fastening and contact with the bottom of the compartment. It is responsible for efficiently transferring the heat of the coolant flowing through it to the cold plate structure via convection, and finally conducting the heat to the seawater. The internal flow channels of the heat exchange plate 303 are mainly in parallel, and it is designed as a bottom flow resistance type cold plate. The heat exchange plate 303 can also increase the rigidity of the bottom of the compartment. The water pump 301 and the expansion tank 306 are arranged near the heat exchange plate 303 to reduce the length of the internal pipeline 302. Temperature and flow sensors 304 are installed on the internal pipeline 302. Internally, they are used to connect the water pump 301, expansion tank 306 and heat exchange plate 303 inside the liquid-cooled supply unit 3. Externally, they are used to connect the liquid-cooled supply unit 3 to the supply pipeline 5 and the return pipeline 6. The unit frame 309 is used to fix the internal pipeline 302 and is located above the heat exchange plate 303.

[0047] In some embodiments, the unit frame 309 is equipped with a display and control module 305 and an interior temperature sensor 308.

[0048] The cabin temperature sensor 308 is connected to the display and control module 305, and the cabin temperature sensor 308 is used to monitor the cabin temperature.

[0049] The display and control module 305 is also connected to the leakage detector 307, the pressure booster valve 9, and the temperature and flow sensors 304 of the liquid cooling supply unit 3.

[0050] like Figure 2 As shown, a display and control module 305 and an internal temperature sensor 308 are installed on the top of the unit frame 309. The internal temperature sensor 308 is responsible for monitoring the temperature of the cabin, and the display and control module 305 is responsible for processing and uploading the data from the temperature sensor 308, the leakage detector 307, the pressure boosting valve 9, and the liquid cooling supply unit 3, as well as the temperature and flow rate data from the other sensors 304.

[0051] The leak detector 307 is installed on the right side of the heat exchange cold plate 303 and fixed at the bottom of the inner cavity of the compartment 1. It is responsible for monitoring the leakage of the liquid cooling supply unit and the leakage of the electronic compartment.

[0052] In some embodiments, the outer surface of the cabin frame 101 is provided with external annular reinforcing ribs 105 and external transverse reinforcing ribs 106 to improve the rigidity and immersion heat dissipation area of ​​the cabin 1. Specifically, the external annular reinforcing ribs 105 and external transverse reinforcing ribs 106 can further greatly improve the rigidity and immersion heat dissipation area of ​​the cabin 1. The cabin 1 is made of high-strength, high-thermal-conductivity 7-series aluminum alloy, which has good overall thermal conductivity and compressive strength, is lightweight, and is easy to process and form as a whole, without welds or internal defects caused by casting that affect strength. The edges of the cabin frame 101 are chamfered with a certain curvature to reduce the pressure on each surface of the cabin.

[0053] The high-pressure-resistant and highly sealed electronic compartment of this application can meet the requirements of efficient space utilization integration and maintainability, has good immersion heat dissipation capability, has the ability to provide liquid cooling supply for other equipment, can withstand ultra-high pressure in the deep sea and has super strong sealing capability, and can effectively test its pressure resistance and sealing performance before the electronic compartment is launched.
