[0001] This utility model belongs to the field of underwater exploration technology, and in particular to a lightweight, high-pressure-resistant, water-cooled electronic cabin. Background Technology

[0002] The underwater electronics compartment serves as the control center for various underwater devices. It primarily consists of a cylindrical body and upper and lower sealed covers. Inside, it houses the underwater control electrical unit, including underwater equipment units, control units, sensing units, power distribution units, optical modules, and heat sinks. The electronics compartment operates in a fully enclosed, atmospheric-pressure environment. The internal modules connect to external equipment such as sonar, power supply compartments, and control compartments via watertight connectors on the upper and lower covers, acting as a crucial link and bridge for detecting relevant underwater parameters.

[0003] Currently, underwater equipment is typically integrated into an electronics compartment. The size and weight of the electronics compartment vary depending on the pressure resistance and the size and quantity of the integrated equipment, especially in the deep-sea field where the compartment is generally heavy, requiring high buoyancy from the installation platform. Furthermore, the equipment within the electronics compartment often needs heat dissipation, necessitating a reasonable arrangement based on the heat generated by the equipment. Existing electronics compartments generally use solid flat end caps of a certain thickness to meet different water pressure requirements, and the compartment walls are also relatively thick, resulting in a heavy electronics compartment.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figure 1 , Figure 2 As shown, this lightweight, high-pressure-resistant, water-cooled electronic compartment includes an electronic compartment body 1, a sealed end cap 2, a communication power supply cable 3, and an internal electronic compartment module 4. The sealed end cap 2 is fixed above the electronic compartment body 1, the communication power supply cable 3 is fixed on the upper surface of the sealed end cap 2, and the internal electronic compartment module 4 is located inside the electronic compartment body 1 and is connected and fixed to the lower surface of the sealed end cap 2.

[0028] like Figures 3-6As shown, the electronic compartment cylinder 1 is a bottomed cylinder with a circular arc bottom surface 14 to increase its pressure resistance. The circular arc bottom surface 14 is surrounded by honeycomb grooves 15 of a certain size and density, which reduces the weight of the cylinder and the load on the platform while meeting pressure resistance requirements. The electronic compartment cylinder 1 can also be a bottomless cylinder. Reinforcing ribs 11 of a certain cross-section are provided on the outer circumference of the electronic compartment cylinder 1 according to the pressure resistance requirements. The number and spacing of the reinforcing ribs 11 are determined based on the actual situation.

[0029] The upper surface of the sealing end cap 2 is provided with a connecting through hole 24, a cover lifting thread hole 25, a power supply connector mounting hole 22, an airtightness test hole 23, and a communication connector mounting hole 21. The power supply connector mounting hole 22 and the communication connector mounting hole 21 are connected to the communication power supply cable 3. The cover lifting thread hole 25 is evenly distributed along the circumferential direction of the edge of the sealing end cap 2 and is used to install the cover lifting screws that separate the sealing end cap 2 from the electronic cabin cylinder 1, so as to facilitate disassembly. The airtightness test hole 23 is used to test the sealing performance after the electronic cabin is integrated to ensure reliable sealing.

[0030] The inner edge of the sealing end cap 2 is provided with one or two sealing grooves 28, and a sealing ring 48 is embedded in the sealing groove 28. The lower surface of the sealing end cap 2 is provided with an end cap honeycomb groove 27 and an end cap threaded hole 26. The end cap threaded hole 26 is connected to the heat-conducting block of the electronic compartment through a long screw 47. The top edge of the electronic compartment cylinder 1 is provided with a raised flange 12, and the raised flange 12 is provided with an electronic compartment threaded hole 13 for connecting and supporting the sealing end cap 2. The number, position and size of the electronic compartment threaded holes 13 match the connecting through hole 24 of the sealing end cap 2. The electronic compartment cylinder 1 and the sealing end cap 2 are connected and fixed through the electronic compartment threaded holes 13 and the connecting through hole 24, and are sealed by the sealing ring 48.

[0031] The internal module 4 of the electronic compartment includes an electronic compartment heat-conducting block, an electronic compartment internal component box 46, an electronic compartment internal mounting circular plate 43, and a power module 45. The electronic compartment internal component box 46 is connected and fixed to the electronic compartment heat-conducting block. The upper part of the electronic compartment heat-conducting block is connected and fixed to the sealing end cover 2 through a long screw 47. The lower part of the electronic compartment heat-conducting block is connected and fixed to the electronic compartment internal mounting circular plate 43 through a short connecting screw 44. The power module 45 is fixed on the electronic compartment internal mounting circular plate 43.

[0032] The electronic compartment heat-conducting blocks include a right heat-conducting block 41 and a left heat-conducting block 42. The right heat-conducting block 41 and the left heat-conducting block 42 have the same structure and are symmetrically distributed. The internal component box 46 of the electronic compartment is fixed between the right heat-conducting block 41 and the left heat-conducting block 42. The outer arc surfaces of the right heat-conducting block 41 and the left heat-conducting block 42 are in close contact with the inside of the electronic compartment cylinder 1 to ensure good heat dissipation contact.

[0033] like Figure 7As shown, the top of the left heat-conducting block 42 is provided with a connecting hole 422 for connecting the long screw 47, the bottom of the left heat-conducting block 42 is provided with a threaded hole 423 for connecting the short connecting screw 44, and the inner side of the left heat-conducting block 42 is provided with a mounting groove 421 for placing the circuit board and its horizontally fixed heat-conducting plate. The right heat-conducting block 41 has the same structure as the left heat-conducting block 42.

[0034] like Figure 8 As shown, the internal mounting circular plate 43 of the electronics compartment is equipped with a power supply mounting boss 431, a circular plate fixing hole 432, and a small component mounting hole 433. A power supply module 45 is fixedly connected to the power supply mounting boss 431. The circular plate fixing hole 432 is connected to the heat-conducting block of the electronics compartment through a short connecting screw 44. Other small components are connected to the small component mounting hole 433. The internal mounting circular plate 43 of the electronics compartment is provided with a contact surface that conforms to the arc surface of the inner surface of the electronics compartment cylinder 1, which effectively reduces the working heat of the power supply. Furthermore, the closed structure formed with the right heat-conducting block 41 and the left heat-conducting block 42 can strengthen the connection strength between the two heat-conducting plates.

[0035] like Figure 9 As shown, the internal component box 46 of the electronic compartment is fixed to the mounting groove 421 of the heat-conducting block of the electronic compartment by the locking strips 462 on both sides. The internal component box 46 of the electronic compartment is provided with a module base 461 for heat conduction. The heat of the components or circuit board is conducted through the module base 461 to the right heat-conducting block 41 and the left heat-conducting block 42, and then conducted to the electronic compartment cylinder 1 and discharged outside the cylinder.

[0036] This invention combines honeycomb grooves on the inner side of the end cap with reinforcing ribs on the outer circumferential surface of the cabin. While ensuring pressure resistance, it effectively reduces the weight of the electronic cabin and alleviates the load on the platform. Internally, it employs a structure with two heat-conducting plates mounted on the sealed end cap, providing excellent heat dissipation. The structure is simple and convenient to install, easy to maintain, and features a modular design with strong functional replaceability. The number of reinforcing ribs on the electronic cabin wall and the size and density of the honeycomb holes in the end cap can be adjusted according to the water pressure to achieve a lighter electronic cabin under the same conditions.

[0037] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
