Description

Technical Field

[0001] This utility model relates to the field of communication cabinet technology, and in particular to a communication cabinet with a circulating drying effect. Background Technology

[0002] Communication cabinets, as the core mounting carriers for electronic components such as communication equipment, power control modules, and network switches, are widely used in various scenarios including telecommunications base stations, data centers, industrial parks, and outdoor communication sites. In these scenarios, the electronic components inside the communication cabinets have extremely stringent requirements for the temperature and humidity of the operating environment, especially the humidity level. When the ambient humidity exceeds 60%, the metal contacts of the electronic components are prone to oxidation and corrosion, and condensation may form on the surface of the circuit boards, leading to decreased insulation performance, signal transmission interference, and even short-circuit faults. This seriously affects the stability and lifespan of the communication system, so a drying device is needed to dehumidify the internal environment of the communication cabinet.

[0003] Currently, the existing drying method for communication cabinets is active ventilation drying. This method uses ventilation fans or louvers on the cabinet to dehumidify by the convection of dry air from the outside and humid air inside the cabinet. However, this method is greatly affected by the external environment. When the humidity of the outside environment is high (such as during the rainy season in the south or in humid coastal areas), ventilation will actually bring more moisture into the cabinet, resulting in the opposite of the desired moisture-proof effect. At the same time, the ventilation structure can easily introduce dust, insects and other impurities, which may cause dust accumulation and short circuits in components or biological corrosion, further reducing the reliability of equipment operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a communication cabinet with a circulating drying effect, which solves the problem that existing communication cabinet drying devices are easily affected by external factors and can easily introduce impurities such as dust and insects, which may cause dust accumulation and short circuits or biological corrosion of components, further reducing the reliability of equipment operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A communication cabinet with a circulating drying effect includes;

[0007] The cabinet, which is existing technology, is used to install and protect communication equipment, and the air inside is in a circulating state.

[0008] A drying unit is used to hold a desiccant that can absorb moisture, and it works in conjunction with the desiccant to absorb moisture from the airflow passing over the surface.

[0009] The circulation mechanism drives the air inside the cabinet to circulate, and the air inside the cabinet passes through the drying mechanism during the circulation process.

[0010] Preferably, a partition is fixedly connected to the middle of the inner wall of the cabinet by screws. Two rows of ventilation holes are opened on the surface of the partition. A dustproof net is fixedly connected to the bottom of the partition by screws. The dustproof net covers the ventilation holes to prevent dust and insects from entering. The ventilation holes allow air from the bottom of the partition to enter the top of the partition and be absorbed by the second fan.

[0011] Preferably, a support plate is fixedly connected to the middle of the inner wall of the cabinet by screws. Several ventilation holes are opened on the surface of the support plate to facilitate the air above the support plate to enter the bottom of the support plate. The support plate is existing technology and is used to support the communication equipment inside the cabinet.

[0012] Preferably, a hollow cavity is formed between the partition plate and the support plate.

[0013] Preferably, the cabinet has several rainproof ventilation holes below the middle partition. These rainproof ventilation holes are existing technology and are used to allow outside air to enter the cabinet and form an external circulation with the fan. The side wall of the cabinet is fixedly connected to the fan with screws, and the fan is used to exhaust the air inside the cabinet to the outside.

[0014] Preferably, the circulation mechanism includes a first fan, an air duct, and a second fan. Both the first fan and the second fan are axial flow fans. The first fan is fixedly connected to the top of the cabinet with screws, the air duct is fixedly connected to the outer wall of the cabinet with screws, and the second fan is fixedly connected to the bottom of the middle partition with screws. The second fan is located on the inner side of the cabinet.

[0015] Preferably, the air outlet of fan one penetrates through the cabinet and faces the inside of the cabinet, the air inlet of fan one penetrates through the duct and faces the inside of the duct, the air outlet of fan two penetrates through the duct and faces the inside of the duct, the air inlet of fan two penetrates through the partition and faces the hollow cavity between the partition and the support plate, fan two draws air from inside the cabinet through the ventilation holes on the surface of the support plate and discharges it into the duct, and fan one draws air from inside the duct and discharges it into the cabinet, forming a circulating air duct.

[0016] Preferably, a protective shell is fixedly connected to the top of the cabinet with screws. The protective shell surrounds the fan and the air inlet of the fan passes through the protective shell. The protective shell is used to protect the fan and prevent it from being damaged by the outside world.

[0017] Preferably, the air duct has a threaded hole on the side away from the cabinet, and the drying mechanism is threaded into the inside of the threaded hole.

[0018] Preferably, the drying mechanism includes a threaded connector that is threadedly connected to a threaded hole. A cylindrical structure is fixedly connected to one side of the threaded connector. Several through holes are opened on the surface of the cylindrical structure. A desiccant, which is silica gel desiccant, is placed inside the cylindrical structure. A rubber ring is fixedly connected to the surface of the threaded connector and contacts the outer wall of the air duct. An end cap is threadedly connected to the end of the cylindrical structure away from the threaded connector. The end cap is used to block the desiccant and prevent the desiccant from falling out of the cylindrical structure.

[0019] This application utilizes a second fan to draw air from inside the cabinet and discharge it into the duct, while a first fan draws air from inside the duct and discharges it into the cabinet, creating an internal air circulation within the cabinet. When the second fan starts, it draws in some outside air through ventilation holes on the surface of the partition plate, along with rainproof ventilation holes. This outside air first passes through a dust filter and is then blown into the duct by the second fan. During this process, moisture is absorbed by the desiccant inside the cylindrical structure. The air is then blown back into the cabinet through the duct and the first fan, forming a partial external circulation. The fan continuously blows the airflow from inside the cabinet to the outside, increasing the airflow velocity within the cabinet. The cabinet, in conjunction with the circulation and drying mechanisms, forms a dual-circulation ventilation and drying structure with internal circulation as the primary method and external circulation as a secondary method. This structure is less affected by external factors and provides better ventilation and drying. It solves the problem that existing communication cabinet drying devices are easily affected by external factors and can easily introduce dust, insects, and other impurities, potentially causing dust accumulation, short circuits, or biological corrosion of components, further reducing the reliability of the equipment.

[0029] The current drying method for communication cabinets is active ventilation drying, which uses ventilation fans or louvers on the cabinet to dehumidify by the convection of dry air from the outside and humid air inside the cabinet. However, this method is greatly affected by the external environment. When the humidity of the outside environment is high (such as during the rainy season in the south or in humid coastal areas), ventilation will bring more moisture into the cabinet, resulting in the opposite of the moisture-proof effect. At the same time, the ventilation structure can easily introduce dust, insects and other impurities, which may cause dust accumulation and short circuits in components or biological corrosion, further reducing the reliability of equipment operation.

The side wall of the cabinet 100 is fixedly connected to the fan 104 by screws. The fan 104 is used to exhaust the air inside the cabinet 100 to the outside.

[0039] like Figure 2 and Figure 4As shown, the circulation mechanism 200 includes a first fan 201, an air duct 202, and a second fan 203. Both the first fan 201 and the second fan 203 are axial flow fans. The first fan 201 is fixedly connected to the top of the cabinet 100 by screws. The air duct 202 is fixedly connected to the outer wall of the cabinet 100 by screws. The second fan 203 is fixedly connected to the bottom of the middle partition 101 by screws. The second fan 203 is located on the inner side of the cabinet 100.

[0040] like Figure 2 and Figure 4 As shown, the air outlet of fan 1 201 passes through the cabinet 100 and faces the inside of the cabinet 100.

The protective shell 105 surrounds the fan 201, and the air inlet of the fan 201 passes through the protective shell 105.

[0044] This application utilizes fan 203 to draw air from inside cabinet 100 and discharge it into duct 202, while fan 201 draws air from inside duct 202 and discharges it into cabinet 100, thus creating internal air circulation within cabinet 100. Furthermore, when fan 203 starts, it draws in some outside air through ventilation holes on the surface of partition 101 in conjunction with rainproof ventilation holes 103. This outside air first passes through a dust filter and is then blown into duct 202 by fan 203. During this process, it is... The desiccant inside the cylindrical structure 303 absorbs moisture and is then blown into the inside of the cabinet 100 through the air duct 202 and the fan 201, forming a local external circulation.
