[0030] The following description, in conjunction with the accompanying drawings, describes a marine electrical cabinet according to an embodiment of the present invention.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The present invention aims to provide an embodiment of an electrical cabinet for ships.

[0032] In this embodiment, a marine electrical cabinet mainly includes a cabinet body 100, a heat pipe 110, and a condenser box 140.

[0033] Cabinet 100 is used to house components.

[0034] For heat pipe 110, heat pipe 110 is installed on the cabinet wall of cabinet 100. Heat pipe 110 has evaporation section 120 and condensation section 130. Evaporation section 120 contacts the heating element inside cabinet 100 to absorb heat and transfer the heat to condensation section 130. Condensation section 130 extends through the cabinet wall of cabinet 100 to the outside of cabinet 100.

[0035] It is understandable that the evaporation section 120 of the heat pipe 110 absorbs heat from the heat-generating components and quickly transfers the heat to the condensation section 130 outside the cabinet 100 for heat dissipation, which makes the heat dissipation efficiency of the electrical cabinet high. At the same time, the heat pipe 110 replaces the traditional fan to achieve holeless heat dissipation, preventing salt spray from entering the cabinet through the fan vent.

[0036] In some specific embodiments, the evaporation section 120 and the heating element are bonded and fixed together by nano-silver thermally conductive adhesive.

[0037] Understandably, nano-silver thermal conductive adhesive has high thermal conductivity and ductility, enabling seamless contact between heating components and the evaporation section 120, avoiding poor contact problems caused by the aging of traditional thermal conductive silicone grease, and is especially suitable for ship vibration environments.

[0038] In some specific embodiments, the top surface of the cabinet 100 is provided with a first hydrophobic layer 170, and the top surface of the cabinet 100 has an inverted "V" shape structure that is high in the middle and low on both sides.

[0039] Understandably, the inverted V-shaped top surface, combined with the hydrophobic layer, forms a highly efficient drainage structure, which can quickly drain surface water in the high salt spray environment of ships, avoid corrosion of the top surface of the cabinet, and eliminate the risk of water accumulation and leakage of traditional flat top covers.

[0040] Specifically, the first hydrophobic layer 170 can be formed by applying commercially available hydrophobic coatings such as silicone hydrophobic coatings, fluorocarbon resin hydrophobic coatings, and acrylic hydrophobic coatings.

[0041] In some specific embodiments, an activated carbon partition plate 180 is provided inside the cabinet 100. 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. 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.

[0042] Understandably, the activated carbon partition 180 can construct a dual physical and chemical moisture-proof system within the cabinet 100. It creates a humidity gradient through the chamber separation, making the humidity of the second chamber 200 lower than that of the first chamber 190. It also uses activated carbon to adsorb moisture that seeps through the gaps in the wires, effectively reducing the humidity in the component area.

[0043] 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. 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 inside the cabinet 100, and the second plate portion 260 is slidably disposed inside the cabinet 100. The second plate portion 260 slides to open or close the first cavity 190 and the second cavity 200.

[0044] Understandably, the sliding second plate 260, together with the inspection door 240, forms a modular maintenance structure. During maintenance, only the sliding second plate 260 needs to be slid to connect the first cavity 190 and the second cavity 200, which makes it convenient for maintenance personnel to repair the components in the first cavity 190 through the inspection port 230 via the second cavity 200, thereby improving maintenance efficiency and maintaining the airtightness in the non-maintenance state.

[0045] Furthermore, the access port 230 is provided with a sealing strip 270, which abuts against the access door 240 to seal, thereby improving the sealing performance between the access door 240 and the access port 230.

[0046] In some specific embodiments, the cabinet 100 is provided with a slide rail 280, and the second plate 260 slides on the slide rail 280, thereby making the sliding of the second plate 260 more stable and effortless.

[0047] In some specific embodiments, a first motor 290 is provided inside 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 260. The first motor 290 drives the first screw 300 to rotate so as to drive the second plate 260 to slide, thereby improving the efficiency of the movement operation of the second plate 260 and eliminating the need for manual movement of the second plate 260.

[0048] In some specific embodiments, the second chamber 200 is provided with an exhaust fan 310, which is located between the activated carbon partition plate 180 and the components. The exhaust fan 310 is used to draw the moisture in the second chamber 200 toward the activated carbon partition plate 180.

[0049] Understandably, by using the exhaust fan 310 to actively draw the moisture from the second chamber 200 to the activated carbon partition plate 180, an active dehumidification effect is achieved, which is beneficial to further improve the dehumidification effect.

[0050] 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 from the humidity sensor 320, compare it with the set humidity, and control the on / off switch of the exhaust fan 310.

[0051] Understandably, the humidity sensor 320 monitors the humidity inside the second chamber 200. The controller receives the detection information from the humidity sensor 320 and compares it 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 the moisture toward 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 allows for 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 in conjunction with the activated carbon partition plate 180 when the humidity in the second chamber 200 is high. This avoids the exhaust fan 310 being constantly running and consuming excessive energy.

[0052] For the condenser box 140, the condenser box 140 is located outside the cabinet 100. The interior of the condenser box 140 is filled with phase change material 150. The condensation section 130 penetrates the box wall of the condenser box 140 and inserts the phase change material 150 to dissipate heat. The outer side of the box wall of the condenser box 140 is provided with heat dissipation fins 160.

[0053] Specifically, the phase change material 150 can be water, paraffin, nitrates, etc.

[0054] It is understandable that by bringing the condensing section 130 into contact with the phase change material 150, the heat dissipation efficiency of the condensing section 130 can be improved. At the same time, by providing heat dissipation fins 160 on the outer side of the condensing box 140, the heat dissipation area of ​​the condensing box 140 can be increased.

[0055] This invention utilizes a heat pipe 110 and a condenser box 140. The heat pipe 110 replaces the traditional fan to achieve poreless heat dissipation, preventing salt mist from entering the cabinet through the fan vent. Simultaneously, it effectively avoids abnormal heat dissipation caused by salt mist damaging the fan in the marine environment. The condenser section 130, combined with the phase change material 150, achieves efficient heat dissipation, while the heat dissipation fins 160 enhance the heat dissipation area. Therefore, the electrical cabinet can maintain efficient heat dissipation in the high-humidity environment of a ship while achieving a fully enclosed cabinet structure 100, ensuring the cabinet's airtightness, reducing component failure rates, and extending the lifespan of the components inside the electrical cabinet.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
