Description

Technical Field

[0001] This utility model relates to the field of network cabinet technology, and more particularly to the field of network cabinet heat dissipation technology, specifically referring to a heat dissipation device for a network cabinet in a ship's equipment room. Background Technology

[0002] A network cabinet is a dedicated cabinet used to house network equipment and servers. It is typically used in data centers, server rooms, or enterprise network infrastructure. Its main functions are to protect equipment, optimize space, manage heat dissipation, and provide good power management. With the continuous improvement of shipboard informatization, network cabinets in shipboard equipment rooms are gradually becoming a core component of shipboard electronic equipment and network communication systems. The normal operation of network cabinets and the electronic equipment within them is crucial for the safe and efficient operation of ships.

[0003] However, network cabinets face numerous challenges when ships operate in the marine environment, especially in terms of heat dissipation. Traditional network cabinets in shipboard equipment rooms typically rely on fans for cooling. Fan cooling depends on airflow, but in the confined environment of a cabinet, airflow is restricted, and the airflow generated by the fan cannot effectively cover all the devices inside. This results in heat not being dissipated in time in certain areas of the network cabinet, leading to localized overheating. Insufficient heat dissipation keeps the devices inside the cabinet in a high-temperature environment for extended periods, potentially causing performance degradation, frequent restarts, and even equipment malfunctions or failures, impacting the safety of ship navigation.

[0004] Therefore, there is a need for a rapid heat dissipation device suitable for network cabinets in ship equipment rooms that can quickly and effectively dissipate heat inside the network cabinet. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 6 The diagram illustrates a heat dissipation device for a network cabinet in a ship's equipment room. It includes a cabinet body 11, an opening on the front side of the cabinet body, a cabinet door 12 within the opening, a ceramic plate layer 14 arranged parallel to the inner wall of the cabinet body 11 in a cabinet cavity 13, forming a U-shaped cavity 15 between the ceramic plate layer 14 and the inner wall of the cabinet body 11, and at least one first air inlet 16 on the ceramic plate layer 14. An air supply assembly and an air extraction assembly are arranged on the top of the cabinet body 11, and a first air outlet is located on the top of the cabinet body 11 corresponding to the position of the air extraction assembly. Figure 1 and Figure 2 As shown, the air supply assembly includes a fan 21, a filter box 23, and an air distribution pipe 22. The air outlet of the fan 21 is connected to the U-shaped cavity 15 sequentially through the filter box 23 and the air distribution pipe 22; Figure 1 and Figure 6 As shown, the air extraction assembly is used to extract air from the cabinet cavity 13, including a fan 42 disposed above the first air outlet; as Figure 3 and Figure 5 As shown, a serpentine heat exchange tube 33 is arranged parallel to the ceramic plate layer 14 in the U-shaped cavity 15. The serpentine heat exchange tube 33 is arranged along the center line of the U-shaped cavity, which is equivalent to the serpentine heat exchange tube 33 being arranged in a U-shape between the inner wall of the cabinet 11 and the ceramic plate layer 14, located in the middle between the inner wall of the cabinet 11 and the ceramic plate layer 14. The two ends of the serpentine heat exchange tube 33 are connected to the water circulation component. The fan 21 is located at the top of the cabinet 11 and is used to drive external air into the cabinet 11, which is connected to the filter box 23 through a pipe. During use, the heat dissipation device, through the coordinated action of the air supply component, the air extraction component, the serpentine heat exchange tube 33 and the water circulation component, keeps the cabinet cavity 13 at a low temperature, ensuring stable operation of the equipment in a low-temperature environment, avoiding local overheating caused by insufficient heat dissipation, and preventing equipment failure or malfunction. The filter box 23 filters dust, moisture and other impurities in the air, preventing these impurities from adhering to the surface of the equipment and causing short circuits or damage, further extending the service life of the equipment.

[0022] Specifically, such as Figure 5As shown, the water circulation assembly includes a cooling water tank 31 and a water pump 32 located at the bottom of the cabinet 11. The cooling water tank 31 is fixed to the bottom of the cabinet 11. A cooling component for cooling the water is installed inside the cooling water tank 31. A cooling component for cooling the ceramic plate layer 14 is installed inside the cooling water tank 31. The water pump 32 is fixed to the bottom of the cooling water tank 31. The inlet of the water pump 32 is located inside the cooling water tank 31, close to the inner bottom wall of the cooling water tank 31. The outlet of the water pump 32 is connected to the inlet of the cooling water tank 31 through a serpentine heat exchange tube 33. Through holes are provided on the bottom plate of the cabinet 11 at the positions corresponding to the two ends of the serpentine heat exchange tube 33. The serpentine heat exchange tube 33 passes through the through holes and is connected to the water circulation assembly. Both ends of the serpentine heat exchange tube 33 penetrate the top of the cooling water tank 31. The inlet of the serpentine heat exchange tube 33 is connected to the outlet of the water pump 32. Water is transported to the serpentine heat exchange tube 33 by the water pump 32. After the water flows through the serpentine heat exchange tube 33, it flows into the cooling water tank 31 through the outlet of the serpentine heat exchange tube 33 and the inlet of the cooling water tank 31. A water circulation channel is constructed based on the cooling water tank 31, the serpentine heat exchange tube 33 and the water pump 32 to cool the air in the U-shaped cavity.

[0023] Specifically, the air distribution pipe 22 is a U-shaped pipe composed of three pipe sections. Each pipe section has several branch pipes 22 evenly arranged on it, and the air distribution pipe 22 and the U-shaped cavity 15 are connected through the branch pipes 24. By setting the air distribution pipe and the branch pipes, the air can be evenly distributed into the U-shaped cavity, which is conducive to the full heat exchange between the air and the serpentine heat exchange pipe.

[0024] Specifically, such as Figure 2 As shown, the filter box 23 includes a square box body 231 with an open top and a box cover 232 that fits the top of the box body 231. Inside the box body 231, between the air inlet and the air outlet of the filter box 23, several filter layers 233 are arranged parallel to each other, and the distance between adjacent filter layers 233 is the same. The box body 231 is fixedly installed on the top of the cabinet 11. A connecting pipe is installed through the outer end of the box body 231 away from the fan 21, and the filtered air is delivered to the air distribution pipe 22 through the connecting pipe.

[0025] Specifically, the box body 231 and the lid 232 are connected by magnets. A square-ring-shaped first magnet 234 is disposed on the top of the box body 231, and a square-ring-shaped second magnet 235 is fixedly disposed on the bottom of the lid 232. The magnetic poles of the sides of the first magnet 234 and the second magnet 235 that are in contact with each other are opposite in direction; that is, the magnetic poles on the top surface of the first magnet 234 and the magnetic poles on the bottom surface of the second magnet 235 are opposite in direction. An annular groove is formed on the top of the box body 231, and the first magnet 234 is disposed in the annular groove and fixedly connected to the inner wall of the annular groove. The size and shape of the second magnet 235 are adapted to the annular groove to ensure a tight seal between the lid 232 and the box body 231.

[0026] Specifically, such as Figure 6 As shown, the air extraction assembly also includes a protective cover 41, which is located on the top of the cabinet 11. A fan 42 is located inside the protective cover 41, and the top of the protective cover 41 has several ventilation holes. Driven by the fan 42, the air inside the cabinet 11 is extracted to the outside of the cabinet 11, achieving rapid cooling and preventing insufficient heat dissipation that could lead to localized overheating of the equipment, thus preventing equipment malfunction or failure.

[0027] Specifically, such as Figure 4 As shown, square first air inlets 16 are provided at the bottom of the two opposite sides of the ceramic plate layer 14. The first air inlets 16 are located at the bottom of the cabinet cavity 13, and the fan 42 is located at the top of the cabinet body 11, so that clean, low-temperature air enters the cabinet cavity 13 from the bottom of the cabinet cavity 13, fully exchanges heat with the network cabinet, and the heat-exchanged air is then discharged from the top of the cabinet body 11 through the fan 42 and the first air outlet.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, on the two opposite inner sidewalls of the ceramic plate layer 14 in the cabinet cavity 13, a plurality of first fins 17 are arranged in sequence close to the ceramic plate layer 14. The multiple first fins 17 are arranged parallel to each other and perpendicular to the bottom plate of the cabinet body 11. The distance between adjacent first fins 17 is the same. The bottom plate of the cabinet body 11 is provided with a first through hole 18 corresponding to the position of each first fin 17. The bottom of the first fin 17 passes through the first through hole 18 and is inserted into the interior of the cooling water tank 31. The first fins 17 are fixedly connected to the ceramic plate layer 14. One end of each of the multiple first fins 17 passes through the top of the cooling water tank 31 and is immersed in the water in the cooling water tank 31. The first fins 17 cool the ceramic plate layer 14, so that the inner surface of the ceramic plate layer 14 is always at a low temperature.

[0029] Specifically, such as Figure 5 As shown, the cooling assembly includes a thermoelectric cooler 34. The thermoelectric cooler 34 is installed through mounting holes provided on the bottom plate or side wall of the cooling water tank 31, cooling the water inside the tank. The cold end of the thermoelectric cooler 34 is located inside the cooling water tank 31, and the hot end is located outside. A second fin 35 is provided at the cold end of the thermoelectric cooler 34, and a third fin 36 is provided at the hot end. The thermoelectric cooler 34 is fixedly mounted on the inner wall of the mounting holes, and the second fins 35 are equidistantly fixed at the cold end of the thermoelectric cooler 34. When the thermoelectric cooler 34 is energized, the temperature of its cold end drops rapidly, working in conjunction with the multiple second fins 35 to cool the water inside the cooling water tank 31.

[0030] Specifically, support feet are provided at the bottom of the cooling water tank 31 or at the corners of the bottom of the cabinet 11.

[0031] The specific working state of the heat dissipation device for a network cabinet in a ship's equipment room provided by this utility model is as follows: When using the cooling device, the entire network cabinet or the equipment inside the network cabinet is installed in the cabinet cavity 13. After injecting a large amount of clean water into the cooling water tank 31, the thermoelectric cooler 34 and the water pump 32 are turned on. The temperature value of the cold end of the thermoelectric cooler 34 is set, and the temperature of the cold end of the thermoelectric cooler 34 drops rapidly. In conjunction with multiple second fins 35, the water is cooled to the set value. The water pump 32 drives the cold water to flow through the serpentine water pipe, which quickly reduces the surface temperature of the serpentine water pipe and cools the air inside the U-shaped cavity 15. At the same time, multiple first fins 17, which are in direct contact with the water in the cooling water tank 31, cool the ceramic plate layer 14, keeping the inner surface temperature of the ceramic plate layer 14 at a low temperature, thus reducing the ambient temperature inside the cabinet cavity 13. Simultaneously with activating the water circulation component, the blower 21 and fan 42 are started. The blower 21 draws outside air into the filter box 23, where multiple filter layers 233 filter out dust, moisture, and other impurities. The dry, clean air is then evenly distributed into the U-shaped cavity 15 via the air distribution pipe 22 and branch pipe 24. The low-temperature, dry air in the U-shaped cavity 15 enters the cabinet 13 from the bottom through the two first air inlets 16 and is blown onto the surface of the equipment to cool it down. The fan 42 extracts air from the cabinet 13 to prevent insufficient heat dissipation and localized overheating, thus preventing equipment malfunction or failure.

[0032] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
