Description

Technical Field

[0001] This utility model relates to the field of network cabinet ventilation structure technology, specifically a network cabinet ventilation structure with heat dissipation duct. Background Technology

[0002] A network cabinet is a device that provides a suitable environment and security protection for the normal operation of electronic equipment. Depending on the type, they are often divided into server cabinets, wall-mounted cabinets, network cabinets, standard cabinets, and intelligent protective outdoor cabinets. During the operation of the equipment, the network cabinet will generate a certain amount of heat, so ventilation devices need to be installed to dissipate the heat.

[0003] A search revealed an existing patent (publication number: CN25855698U) disclosing a network cabinet with a ventilation structure, belonging to the field of network cabinet technology. The patent includes a chassis with a ventilation structure on its upper part to assist in ventilation; a movable structure on its upper part to assist in fixing internal electronic components; and a heat dissipation structure on its upper part to assist in heat dissipation. The heat dissipation structure includes a water tank installed on the bottom wall of the chassis, and a water pump is connected to the outer wall of a metal pipe. By setting up the heat dissipation structure, a heat pipe is connected to a metal pipe via a water pipe connector. Electronic components are then placed on the heat pipe. When the water pump is started, coolant is transferred to the heat pipe. When the water pump is turned off, the heat generated by the electronic components during operation is directly absorbed by the coolant and then cooled by the heat dissipation fins. This timely heat dissipation and cooling of the electronic components prevents overheating and reduces the lifespan and damage of the electronic components.

[0004] Although it can dissipate heat, it has its shortcomings. When it dissipates heat through a fan, external air enters the cabinet, but the external air sometimes has a high moisture content, which will affect the lifespan of the internal components of the cabinet. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a network cabinet ventilation structure with heat dissipation ducts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a network cabinet ventilation structure with heat dissipation duct, comprising a circular shell, an isolation plate fixed inside the circular shell, silica gel desiccant located above and below the isolation plate inside the circular shell, a through-hole opening on the left side of the circular shell, a cabinet body rotatably connected to the left side of the circular shell, an air duct fixed inside the cabinet body, two through openings on the rear side of the cabinet body, and fixed frames fixed at the top and bottom of the air duct.

[0007] The top of the fixed frame has multiple vertically penetrating air holes. A partition plate is fixed inside the air duct. A turbine fan is located below the partition plate inside the air duct. Connecting blocks are fixed in front of and behind the turbine fan. The connecting blocks are fixedly connected to the air duct. An intercepting net is fixed inside the air outlet. The top of the fixed frame has an opening.

[0008] Preferably, the right side of the circular shell has two fixed air guide covers.

[0009] Preferably, the bottom of the cabinet is fixed with support legs.

[0010] Preferably, the interception net is made of stainless steel.

[0011] Preferably, a motor is fixed inside the air duct, and the output shaft of the motor passes through the cabinet and is fixedly connected to the cylindrical shell.

[0012] Preferably, a timer and a PLC are fixed inside the air duct, located in front of and behind the motor, respectively. Beneficial effects

[0013] This invention provides a network cabinet ventilation structure with heat dissipation ducts. Compared with the prior art, it has the following advantages:

[0014] This network cabinet ventilation structure with heat dissipation ducts consists of a circular shell, ducts, partitions, and a fixed frame. When the turbine fan is activated, external cool air enters the circular shell through the lower vent, is dried by the silica gel desiccant below, and then enters the interior of the lower duct. It then enters the lower fixed frame and finally the interior of the cabinet, cooling the interior. The hot air then enters the upper fixed frame, enters the upper duct, and is exhausted from the upper vent. The hot air dries the silica gel desiccant on the upper part of the circular shell.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a network cabinet ventilation structure with a heat dissipation duct, including a circular shell 4, an isolation plate 18 fixed inside the circular shell 4, silica gel desiccant 16 located above and below the isolation plate 18 inside the circular shell 4, a through-hole 17 on the left side of the circular shell 4, a cabinet body 2 rotatably connected to the left side of the circular shell 4, an air duct 7 fixed inside the cabinet body 2, two through openings 19 on the rear side of the cabinet body 2, a fixing frame 6 fixed at the top and bottom of the air duct 7, multiple through-holes 15 on the top of the fixing frame 6, a partition plate 12 fixed inside the air duct 7, a turbine fan 8 located below the partition plate 12 inside the air duct 7, connecting blocks 9 fixed at the front and rear of the turbine fan 8, the connecting blocks 9 being fixedly connected to the air duct 7, an intercepting net 3 fixed inside the air duct 17, and an opening 14 on the top of the fixing frame 6, which allows dry gas to enter the cabinet body 2 and extends the service life of the silica gel desiccant 16.

[0023] Furthermore, two air guide covers 5 are fixed on the right side of the circular shell 4 to prevent hot and cold air from mixing. Support legs 1 are fixed at the bottom of the cabinet 2 to prevent moisture from entering the interior of the cabinet 2. The interception net 3 is made of stainless steel, which is durable and not easily damaged. A motor 10 is fixed inside the air duct 7. The output shaft of the motor 10 passes through the cabinet 2 and is fixedly connected to the circular shell 4, so that the circular shell 4 can rotate. A timer 11 and a PLC 13 are fixed in front of and behind the motor 10 in the air duct 7, respectively, so as to control the start and stop of the motor 10.

[0024] During operation, the turbine fan 8 is started, and external cold air enters the circular shell 4 through the lower vent 17. After being dried by the silica gel desiccant 16, the air enters the interior of the lower air duct 7, then enters the lower fixed frame 6, and then enters the interior of the cabinet 2, cooling the interior of the cabinet 2. Then, the hot air enters the upper fixed frame 6, enters the upper air duct 7, and then exits from the upper vent 17. The hot air dries the silica gel desiccant 16 on the upper part of the circular shell 4. After a period of use, the timer 11 sends a signal to the PLC 13, and the PLC 13 starts the motor 10. The motor 10 rotates the circular shell 4, causing the upper and lower silica gel desiccant 16 to be interchanged. This can extend the service life of the silica gel desiccant 16, eliminating the need for frequent replacement of the silica gel desiccant 16. It allows dry air to enter the cabinet 2, preventing humid air from affecting the lifespan of the internal components of the cabinet 2. If used outdoors, a rain cover can be added.
