[0023] An electrical cabinet for a ship according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0024] With reference to Figure 1 , Figure 2 and Figure 3 , the present application aims to provide an embodiment of an electrical cabinet for a ship.

[0025] In the present embodiment, an electrical cabinet for a ship mainly comprises a cabinet body 100, a heat pipe 110 and a condenser 140.

[0026] For the cabinet body 100, the cabinet body 100 is used to accommodate components.

[0027] For the heat pipe 110, the heat pipe 110 is arranged on the cabinet wall of the cabinet body 100, the heat pipe 110 has an evaporation section 120 and a condensation section 130, the evaporation section 120 is in contact with the heat-generating components in the cabinet body 100 to absorb heat and transfer the heat to the condensation section 130, and the condensation section 130 extends through the cabinet wall of the cabinet body 100 to the outside of the cabinet body 100.

[0028] It can be understood that the evaporation section 120 of the heat pipe 110 is used to absorb heat from the heat-generating components, and the heat is quickly transferred to the condensation section 130 outside the cabinet body 100 for heat dissipation, so that the heat dissipation efficiency of the electrical cabinet is high, and at the same time, the heat pipe 110 is used to replace the traditional fan to realize non-porous heat dissipation, avoiding the entry of salt mist into the cabinet through the fan port.

[0029] In some specific embodiments, the evaporation section 120 and the heat-generating components are fixedly attached by nano-silver heat-conducting glue.

[0030] It is understandable that nano-silver thermal conductive adhesive has high thermal conductivity and ductility, which can achieve gapless contact between the heating components and the evaporation section 120, avoiding the poor contact problem caused by aging of traditional thermal conductive silicone grease, and is particularly suitable for the vibration environment of ships.

[0031] In some specific embodiments, a first hydrophobic layer 170 is provided on the top surface of the cabinet 100 , and the top surface of the cabinet 100 is in an inverted “V”-shaped structure with a high middle and low sides.

[0032] It can be understood that the inverted V-shaped top surface cooperates with the hydrophobic layer to form an efficient drainage structure, which can quickly drain surface water in the high salt spray environment of the ship, avoid corrosion of the cabinet 100 top surface, and eliminate the risk of water accumulation and leakage in the traditional flat top cover.

[0033] Specifically, the first hydrophobic layer 170 can be formed by coating with commercially available hydrophobic coatings such as silicone hydrophobic coatings, fluorocarbon resin hydrophobic coatings, and acrylic hydrophobic coatings.

[0034] In some specific embodiments, an activated carbon partition plate 180 is provided in the cabinet 100, and the activated carbon partition plate 180 divides the inner cavity of the cabinet 100 into a first cavity 190 and a second cavity 200. The first cavity 190 is used to accommodate components. The activated carbon partition plate 180 has a first through hole 210, and the cavity wall of the second cavity 200 has a second through hole 220. The wires of the components extend to the outside of the cabinet 100 through the first through hole 210 and the second through hole 220.

[0035] It can be understood that the activated carbon partition plate 180 can construct a physical and chemical dual moisture-proof system in the cabinet 100, forming a humidity gradient through chamber separation, so that the humidity of the second chamber 200 is lower than that of the first chamber 190, and using activated carbon to absorb moisture that penetrates through the gaps in the wires, which can effectively reduce the humidity in the component area.

[0036] In some specific embodiments, the cavity wall of the first cavity 190 is provided with an inspection port 230 and an inspection door 240 for opening and closing the inspection port 230, and the activated carbon partition plate 180 includes a first plate portion 250 and a second plate portion 260, the first plate portion 250 is fixed in the cabinet body 100, and the second plate portion 260 is slidably provided in the cabinet body 100, and the second plate portion 260 slides to open or close the first cavity 190 and the second cavity 200.

[0037] It can be understood that the sliding second plate portion 260 cooperates with the inspection door 240 to form a modular maintenance structure. During maintenance, it is only necessary to slide the second plate portion 260 to connect the first cavity 190 and the second cavity 200, so that maintenance personnel can repair the components in the first cavity 190 through the second cavity 200 at the inspection port 230, thereby improving maintenance efficiency and maintaining the sealing in the non-maintenance state.

[0038] Furthermore, the inspection port 230 is provided with a sealing strip 270 , which abuts against the inspection door 240 to form a seal, thereby facilitating improved sealing between the inspection door 240 and the inspection port 230 .

[0039] In some specific embodiments, the cabinet 100 is provided with a slide rail 280 , and the second plate portion 260 slides on the slide rail 280 , thereby making the sliding of the second plate portion 260 more stable and labor-saving.

[0040] In some specific embodiments, a first motor 290 is provided in the cabinet 100, and a first screw 300 is provided at the output end of the first motor 290. The first screw 300 is threadedly connected to the second plate portion 260. The first motor 290 drives the first screw 300 to rotate to drive the second plate portion 260 to slide, thereby helping to improve the moving operation efficiency of the second plate portion 260 and eliminating manual movement of the second plate portion 260.

[0041] In some specific embodiments, the second chamber 200 is provided with an exhaust fan 310 , which is located between the activated carbon separator 180 and the components. The exhaust fan 310 is used to extract moisture from the second chamber 200 toward the activated carbon separator 180 .

[0042] It can be understood that the use of the exhaust fan 310 to actively draw moisture from the second chamber 200 toward the activated carbon partition plate 180 achieves an active dehumidification effect, which is conducive to further improving the dehumidification effect.

[0043] Furthermore, a humidity sensor 320 and a controller are also provided in the second cavity 200. The humidity sensor 320 is electrically connected to the controller, and the controller is electrically connected to the exhaust fan 310. The humidity sensor 320 is used to detect the humidity in the second cavity 200, and the controller is used to receive the detection information of the humidity sensor 320, compare it with the set humidity, and control the switch of the exhaust fan 310.

[0044] It can be understood that the humidity in the second chamber 200 is monitored by the humidity sensor 320, and the controller receives the detection information of the humidity sensor 320 and compares the detection information with the set humidity. When the humidity detected by the humidity sensor 320 is greater than the set humidity, the controller controls the exhaust fan 310 to turn on and blow moisture to the activated carbon partition plate 180. When the humidity detected by the humidity sensor 320 is less than the set humidity, the controller controls the exhaust fan 310 to turn off. This facilitates natural dehumidification using the activated carbon partition plate 180 when the humidity in the second chamber 200 is low, and active dehumidification using the exhaust fan 310 combined with the activated carbon partition plate 180 when the humidity in the second chamber 200 is high, thereby avoiding excessive energy consumption by the exhaust fan 310 being constantly on.

[0045] The condensation box 140 is arranged outside the cabinet 100 , and the interior of the condensation box 140 is filled with a phase change material 150 . The condensation section 130 penetrates the wall of the condensation box 140 and is inserted into the phase change material 150 to dissipate heat. A heat dissipation fin 160 is provided on the outer side of the wall of the condensation box 140 .

[0046] Specifically, the phase change material 150 may be water, paraffin, nitrate, or the like.

[0047] It is understandable that by making the condensing section 130 contact with the phase change material 150, the heat dissipation efficiency of the condensing section 130 can be improved. At the same time, providing heat dissipation fins 160 on the outer side of the box wall of the condensing box 140 can increase the heat dissipation area of ​​the condensing box 140.

[0048] The present invention provides a heat pipe 110 and a condensation box 140, and replaces the traditional fan with the heat pipe 110 to achieve hole-free heat dissipation, thereby preventing salt mist from entering the cabinet through the fan port. At the same time, it effectively avoids heat dissipation abnormalities caused by salt mist in the ship environment damaging the fan; the condensation section 130 is combined with the phase change material 150 to achieve efficient heat dissipation, and the heat dissipation area is enhanced with the heat dissipation fins 160. As a result, the electrical cabinet can not only ensure heat dissipation efficiency in the high humidity environment of the ship, but also achieve a fully enclosed structure of the cabinet body 100, ensure the sealing of the cabinet body 100, reduce the failure rate of components, and help to ensure the life of the components inside the electrical cabinet.
