[0041] The present application proposes an electronic communication cabinet, please refer to Figure 1 , 2, 3, 5, the electronic communication cabinet includes cabinet 1, a plurality of equipment placing plates 2, a first air guide box 3 and a first fan 4. A plurality of groups of first air inlets 11 and first air outlets 12 are arranged on the opposite two side walls of the cabinet 1, and a first air duct is formed between a first air inlet 11 and a first air outlet 12 arranged correspondingly. A plurality of equipment placing plates 2 are arranged in the cabinet 1 at intervals, and the equipment placing plates 2 are used for placing various hardware, and the first air duct is adjacent to the bottom of the equipment placing plate 2. The first air guide box 3 is arranged at the side of the cabinet 1, and the first air guide box 3 is provided with a first air guide cavity 32, and a plurality of first air guide openings 31 are arranged on the first air guide box 3, and the first air guide openings 31 are communicated with the first air inlets 11. The first fan 4 is connected with the first air guide box 3. Wherein, the first fan 4 blows flowing air into the first air guide box 3, and the air enters the first air duct through the first air inlet 11 after passing through the first air guide cavity 32, so as to take away the heat at the bottom of the equipment placing plate 2.

[0042] Specifically, the cabinet 1 can be made of metal material, such as aluminum alloy or stainless steel, to provide sufficient structural strength and heat dissipation performance. The equipment placing plates 2 can be arranged horizontally in the cabinet 1, and the specific number can be adjusted according to actual needs. The first air guide box 3 can be welded or bolted on the side of the cabinet 1, and the shape of the first air guide cavity 32 can be rectangular, trapezoidal or other suitable air guide shapes. The number and size of the first air guide openings 31 can be designed according to the heat dissipation demand, such as uniform distribution or gradual distribution arrangement. The first fan 4 can select an axial fan or a centrifugal fan, and its power and air volume should match the heat dissipation demand.

[0043] The first air duct can have various implementation forms. For example, the first air inlet 11 and the first air outlet 12 can be directly formed by opening a through hole in the side wall of the cabinet 1, or the air duct can be constructed by an additional air guide plate or air guide pipe. The relative position relationship between the equipment placing plate 2 and the first air duct can be adjusted, such as arranging the first air duct directly below or obliquely below the equipment placing plate 2. The installation position of the first air guide box 3 can be optimized according to the structure of the cabinet 1, such as being installed on one side or both sides of the cabinet 1. The communication mode of the first air guide opening 31 can be realized by directly connecting or connecting through a hose.

[0044] Thus, the technical scheme sets the first air duct and the air guide system, which can accurately guide the cooling air to the key heat dissipation area at the bottom of the equipment placing plate 2. Compared with the prior art of setting a dispersion fan at the bottom of the cabinet, the present scheme improves the heat dissipation efficiency by constructing a directional air duct to make the air flow concentrate on the main heat generating part at the connection position between the equipment and the rack. Meanwhile, the structure design of the air guide box can effectively control the air flow direction and speed, avoiding the energy waste caused by air dispersion. The scheme is particularly suitable for communication equipment that needs to be operated stably for a long time, and can effectively solve the problem of local overheating at the bottom of the equipment.

[0045] Further, referring to Figure 6 The present application also proposes that the lower part of the equipment placing plate 2 in the electronic communication cabinet is provided with a sealing plate 21, which is arranged in a spaced manner with the equipment placing plate 2 to form a first air duct.

[0046] Specifically, the sealing plate 21 can be made of metal plate or engineering plastic material, and is fixed on the support frame at both sides inside the cabinet 1 by bolts or buckles. The spacing distance between the sealing plate 21 and the equipment placing plate 2 is preferably 5-10 cm, which can be adjusted according to the actual heat dissipation requirement. Rubber sealing strips can be arranged at the edges of the sealing plate 21 to ensure the sealing with the side wall of the cabinet 1. As a preferred embodiment, the sealing plate 21 can be designed as a detachable structure for easy maintenance and cleaning.

[0047] Thus, by setting the sealing plate 21 and the equipment placing plate 2 to form a closed air duct, the air flow can be prevented from flowing to other areas, and the air flow can be effectively guided to pass through the bottom area of the equipment placing plate 2, thereby significantly improving the heat conduction efficiency of the equipment installation part. Compared with the open bottom heat dissipation structure in the prior art, the design makes the cooling air flow more concentrated on the bottom contact surface of the equipment with the most serious heat, solving the technical problem of air dispersion in the traditional heat dissipation method. At the same time, the sealing structure avoids air leakage, ensuring the maximum heat dissipation efficiency.

[0048] Further, the present application also proposes that the equipment placing plate 2 in the electronic communication cabinet is made of heat conductive material, and a plurality of heat dissipation through holes are arranged on the surface of the equipment placing plate 2.

[0049] Specifically, the heat-conducting material can be aluminum alloy, copper alloy or other metal materials with good heat-conducting performance to ensure that the equipment placement plate 2 can effectively conduct the heat generated by the hardware equipment. The heat dissipation through holes can be circular, square or other shapes and are uniformly distributed on the surface of the equipment placement plate 2 to increase the heat dissipation area and promote air circulation. As a preferred embodiment, the diameter or side length of the heat dissipation through hole can be adjusted according to the actual heat dissipation requirement, for example, a circular through hole with a diameter of 5mm-10mm or a square through hole with a side length of 5mm-8mm. In addition, the arrangement of the heat dissipation through holes can be arrayed or staggered to optimize the heat dissipation effect.

[0050] Therefore, the technical scheme can more efficiently conduct the heat generated by the hardware equipment to the surrounding air through the heat-conducting equipment placement plate 2 combined with the design of the heat dissipation through holes, and the heat can be taken away by air flow. Compared with the traditional cabinet which only relies on the bottom fan for heat dissipation, the scheme can directly dissipate heat in the contact area between the equipment and the placement plate, reduce heat accumulation and improve heat dissipation efficiency. At the same time, the design of the heat dissipation through holes further enhances air circulation, so that the heat can be dissipated faster, thereby reducing the working temperature of the hardware equipment and improving the stability of the equipment operation.

[0051] Further, please refer to Figure 1 、 2 , 4, 5, the application also provides that a plurality of corresponding second air inlets 13 and second air outlets 14 are arranged on the opposite side walls of the cabinet 1, a second air duct is formed between the corresponding second air inlet 13 and the second air outlet 14, and the second air duct is located between the hardware equipment and the sealing plate 21. The electronic communication cabinet further comprises a second air guide box 5 and a second fan 6. The second air guide box 5 is arranged on the side of the cabinet 1, the second air guide box 5 is arranged opposite to the first air guide box 3, the second air guide box 5 is provided with a second air guide cavity 52, a plurality of second air guide openings 51 are arranged on the second air guide box 5, and the second air guide openings 51 are communicated with the second air inlets 13. The second fan 6 is connected with the second air guide box 5. The second fan 6 blows flowing air into the second air guide box 5, the air passes through the second air guide cavity 52 and enters the second air duct through the second air inlet 13 to take away the heat emitted above the hardware equipment.

[0052] The technical scheme realizes targeted heat dissipation of the area above the hardware equipment by adding the second air duct and the second air guide system. The second air duct is located close to the hardware equipment above, which can directly take away the rising hot air flow generated during the operation of the equipment. Through the cooperative work of the double air ducts, the heat dissipation efficiency is significantly improved, and the problem of uneven heat dissipation in the dense equipment area of the communication cabinet is solved. The design is particularly suitable for communication equipment such as switches and servers with large heat generation, which can effectively reduce the working temperature of the equipment and improve the operation stability.

[0053] Further, please refer toFigure 2 、 3 、4、5, the first air guide box 3 is provided with a first through port 33 penetrating through two sides, the first through port 33 is communicated with the second air outlet 14, the second air guide box 5 is provided with a second through port 53 penetrating through two sides, the second through port 53 is communicated with the first air outlet 12; wherein the hot air passing through the first air outlet 12 is discharged through the second through port 53, and the hot air passing through the second air outlet 14 is discharged through the first through port 33.

[0054] Specifically, the first through port 33 and the second through port 53 can adopt a through hole structure in a circular, square or other shape, and the size of the through port can be adjusted according to the actual air volume demand. As a preferred embodiment, the first through port 33 and the second through port 53 can be provided with a flow guide structure, such as a flow guide plate or a flow guide groove, to optimize the airflow direction. Further, a sealing strip can be provided at the edge of the through port to reduce air leakage. In addition, the position of the through port can be flexibly arranged according to the internal structure of the cabinet, for example, arranged at the upper, middle or lower part of the air guide box.

[0055] Therefore, the technical scheme realizes the cross discharge of hot air flow by setting the through port structure communicated with each other. The specific working principle is that: after the hot air flow in the first air duct is discharged from the first air outlet 12, it is guided out through the second through port 53 of the second air guide box 5; at the same time, after the hot air flow in the second air duct is discharged from the second air outlet 14, it is guided out through the first through port 33 of the first air guide box 3. This cross air discharge mode can make the airflow have a clear flow direction, effectively avoid the formation of vortex in the cabinet, and improve the heat dissipation efficiency. At the same time, it is ensured that the air guide boxes are arranged on both sides without affecting the air outlet position. Compared with the prior art, the scheme can more effectively organize the airflow path, make the hot air quickly discharge from the cabinet, and thus improve the overall heat dissipation effect in the cabinet.

[0056] Further, referring to Figure 3 、 4 , the present application also proposes that the cross-sectional area of the first air guide cavity 32 gradually decreases from top to bottom; the cross-sectional area of the second air guide cavity 52 gradually decreases from top to bottom.

[0057] Specifically, the cross-sectional area change of the first air guide cavity 32 and the second air guide cavity 52 can be realized by the following way: the side wall of the air guide box adopts an inclined design, so that the internal space of the cavity gradually shrinks from top to bottom. As a preferred embodiment, the two side walls of the air guide box can be symmetrical inclined surfaces, forming a trapezoidal cross-section air guide cavity. Further, the cross-sectional area change of the air guide cavity can also be realized in a stepped decreasing manner, that is, connected by multiple cavity segments with different diameters. In addition, the cross-sectional area change of the air guide cavity can also be realized by a curved surface transition, so that the airflow flows more smoothly.

[0058] Since the fan is connected to the top of the air guide box, and the distances from the multiple air inlets to the top air inlet of the air guide box are inconsistent, the air flow rate of the air inlet close to the top of the air guide box is fast, and the air flow rate of the air inlet far from the top of the air guide box is slow, resulting in uneven air volume distribution. Therefore, the air guide cavity is designed to have a gradually decreasing cross-sectional area, which can reduce the air flow rate near the top air inlet and increase the air flow rate far from the top air inlet, and after mutual complementation, the air flow rates of the air inlets at each position are as consistent as possible.

[0059] Further, referring to Figure 3 、 4 , the present application also proposes that the sizes of the multiple first air guide inlets 31 gradually increase from top to bottom, and the sizes of the multiple second air guide inlets 51 gradually increase from top to bottom.

[0060] Specifically, the first air guide inlets 31 and the second air guide inlets 51 are designed in a gradual change manner, the air guide inlets at the upper part have a smaller opening size, and the air guide inlets at the lower part have a larger opening size. As a preferred embodiment, the air guide inlets can have a rectangular or circular opening, and the opening area increases in a linear or nonlinear manner. Further, the air guide inlets can have an adjustable louver structure, and the opening size is controlled by a mechanical device.

[0061] Therefore, the technical scheme realizes precise control of air volume distribution by optimizing the size distribution of the air guide inlets. Since the fan is connected to the top of the air guide box, and the distances from the multiple air inlets to the top air inlet of the air guide box are inconsistent, the air flow rate of the air inlet close to the top of the air guide box is fast, and the air flow rate of the air inlet far from the top of the air guide box is slow, resulting in uneven air volume distribution. The gradual change design of the air guide inlets makes more air flow be directed to the lower part, effectively solving the problem of uneven air volume distribution caused by traditional uniform size air guide inlets. Compared with the prior art, the scheme can provide more reasonable air volume distribution under the same fan power, significantly improving the heat dissipation efficiency. Specifically, the upper part is avoided from being excessively cooled, the lower high-temperature area is sufficiently cooled, and the overall temperature distribution is more balanced.

[0062] The first air inlet 11 and the second air inlet 13 are each provided with a dust screen.

[0063] Further, referring to Figure 2 、 5 , 6, the present application also proposes that the electronic communication cabinet includes multiple opening and closing assemblies 7, which are used to open the first air inlet 11 when the hardware devices are placed on the equipment placing plate 2 to ensure heat dissipation, and to block the first air inlet 11 when the hardware devices are not placed on the equipment placing plate 2 to increase the air volume of the other first air inlets 11.

[0064] The opening and closing assembly 7 includes a shielding piece 71, a push plate 72 and a magnetic attraction piece 73. The shielding piece 71 shields the first air inlet 11. The push plate 72 is connected with the shielding piece 71, and the push plate 72 is protrudingly arranged on the upper part of the equipment placing plate 2 and is slidingly arranged front and back. The magnetic attraction piece 73 is located on one side of the push plate 72 and is magnetically connected with the push plate 72. When the hardware equipment is placed on the equipment placing plate 2, the push plate 72 is pushed to move inward, the push plate 72 is disconnected with the magnetic attraction piece 73, the push plate 72 drives the shielding piece 71 to move, the opening of the shielding piece 71 is misaligned with the opening of the first air inlet 11, so as to open the first air inlet 11, and when the hardware equipment is taken out, the magnetic attraction piece 73 magnetically attracts the push plate 72 back to the original position, and the shielding piece 71 is reset to complete shielding.

[0065] Specifically, the shielding piece 71 can be made of a metal plate or a plastic plate, which is matched with the first air inlet 11 in shape to ensure complete shielding. The push plate 72 can be made of light metal or high-strength plastic, and the height of the protruding part thereof can be adjusted according to the thickness of the hardware equipment. The magnetic attraction piece 73 can be made of a permanent magnet or an electromagnet, and the magnetic force can be adjusted as needed to ensure that the push plate 72 can be stably attracted or released. As a preferred embodiment, the push plate 72 and the shielding piece 71 can be connected through a connecting rod or a sliding rail to realize synchronous movement.

[0066] Therefore, the technical scheme realizes the automatic opening and closing of the first air inlet 11 through the setting of the opening and closing assembly 7. When the hardware equipment is placed on the equipment placing plate 2, the push plate 72 is pushed to drive the shielding piece 71 to move, so as to open the first air inlet 11 and ensure the smoothness of the heat dissipation air duct. When the hardware equipment is taken out, the magnetic attraction piece 73 attracts the push plate 72 back to the original position, the shielding piece 71 is reset, and the first air inlet 11 is closed, thereby avoiding the waste of cold air and improving the air intake of other first air inlets 11 to concentrate the wind power to efficiently heat the equipment in need of heat dissipation. The scheme solves the problem of dispersed wind power of the heat dissipation fan in the prior art and cannot accurately dissipate heat, improves the heat dissipation efficiency and reduces the energy consumption. The scheme can accurately distribute the air volume according to the actual equipment distribution, and solves the problem of invalid heat dissipation caused by no equipment in some areas.

[0067] The technical scheme realizes the intelligent control of the first air inlet 11 through the setting of the opening and closing assembly 7. When the hardware equipment is placed on the equipment placing plate 2, the opening and closing assembly 7 automatically opens the corresponding first air inlet 11 to ensure the heat dissipation effect; when the hardware equipment is not placed on the equipment placing plate 2, the opening and closing assembly 7 automatically closes the corresponding first air inlet 11 to concentrate the air volume to other positions in need of heat dissipation. This design effectively solves the problem of dispersed wind power and low heat dissipation efficiency in the prior art, improves the accuracy and energy efficiency ratio of the heat dissipation system. Compared with the prior art, the scheme does not need to additionally set sensors or control circuits, has a simple and reliable structure and low maintenance cost.

[0068] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made under the technical concept of the present application, and based on the content of the present application specification and drawings, is included in the patent protection scope of the present application.
