Description

Technical Field

[0001] The utility model belongs to the relevant technical field of base stations, and in particular relates to an outdoor 5G base station natural cooling cabinet. Background Art

[0002] Most base stations in the northwest region use integrated outdoor cabinets with cabinet-type air conditioners for heat dissipation. However, after more than a year of use, it has been found that the damage rate of air conditioners in various base stations has reached more than 80%. As a result, the temperature of the equipment in the cabinet is easily increased. Operation and maintenance personnel can only open the cabinet door for natural heat dissipation, and when it rains, the operation and maintenance personnel need to close the cabinet door, which easily leads to an increased risk of equipment damage and a very large manpower investment. In addition, the use of base station air conditioners undoubtedly increases equipment costs. Therefore, it is urgent to renovate the integrated outdoor cabinets of each base station.

[0029] Preferably, in order to improve the heat insulation effect, a heat insulation layer 15 is provided inside the cabinet 1 , and the heat insulation effect is improved by adding the heat insulation layer 15 .

[0030] Preferably, in order to facilitate the installation of electronic equipment, a placement rack 13 for placing maintenance equipment and a mounting frame 14 for fixing electronic equipment inside the base station are provided in the cabinet 1. A mounting beam 16 is symmetrically provided on both sides of the cabinet 1, and the placement rack 13 is erected between the two mounting beams 16. By adding the placement rack 13, when the equipment inside the cabinet 1 needs to be repaired later, the maintenance equipment can be placed on the placement rack 13, which is convenient for users to use. In addition, the placement rack 13 can also be used to place electronic equipment inside the cabinet 1 (such as display screens, etc.).

[0031] Preferably, the mounting frame 14 includes four fixed beams 1401 distributed front, back, left and right, and a II-shaped bottom beam 1402. The II-shaped bottom beam 1402 is placed horizontally, and a mounting beam 2 17 is symmetrically arranged on both sides of the cabinet 1. A II-shaped bottom beam 1402 is fixed between the two mounting beams 2 17. The bottoms of the four fixed beams 1401 are fixed to the upper surface of the II-shaped bottom beam 1402, and the tops of the four fixed beams 1401 are connected to the top of the cabinet 1. One or more positioning through holes 18 are arranged at intervals on the fixed beams 1401, and mounting blocks 19 are arranged on the two front fixed beams 1401. One or more mounting through holes 20 are arranged on the mounting blocks 19. In this embodiment, the fixed beams 1401 are covered with positioning through holes 18 to facilitate the later installation of electronic equipment. Moreover, by setting the mounting blocks 19 and setting the mounting through holes 20 on the mounting blocks 19, it is further convenient to hang wiring or fix electronic equipment.

[0032] Preferably, in order to improve the insect-proof effect, the insect-proof mesh cover 9 is a frame-type structure, and a breathable mesh 21 is provided at the bottom of the insect-proof mesh cover 9. In this embodiment, the breathable mesh 21 is provided at the bottom to prevent insects and dust from entering.

[0033] As a preference, in order to improve the air guide effect and allow the wind to enter the cabinet evenly from top to bottom to dissipate the heat of the equipment inside the cabinet, there are two air guide plates 7, which are distributed up and down to form a horizontally placed trumpet-shaped structure.

[0034] Preferably, in order to improve the insect-proof effect, the dust shield 4 is a downwardly inclined structure, and all dust shields 4 are arranged in parallel to form a dust-proof mesh cover. In this embodiment, the dust shield 4 is inclined to prevent dust and insects from flying in from the air inlet.

[0035] Preferably, in order to improve the waterproof effect, a waterproof plate 22 is provided at the bottom of the cabinet 1, and a waterproof gap exists between the waterproof plate 22 and the installation bottom surface. In this embodiment, the waterproof effect is further improved by providing the waterproof plate 22 and having a gap with the bottom.

[0036] The working principle of this structure is as follows: when it is necessary to dissipate heat inside the cabinet 1, the external air is sucked in from the air inlet of the air inlet frame 3 (composed of dust shields 4 arranged at intervals), and then filtered through the air filter 6 before being blown into the cabinet 1 by the heat dissipation fan 5. Since an air guide plate 7 is added to the back of the heat dissipation fan 5, the inhaled air can be evenly dissipated to the equipment in the cabinet 1, thereby improving the heat dissipation effect and the uniformity of heat dissipation. After the heat is dissipated inside the cabinet 1, it is discharged through the exhaust fan 10. Therefore, this structure can dissipate heat inside the cabinet 1 with a relatively simple structure, and it has lower cost, less manpower investment, and less equipment damage. It should be noted that the air filter 6 is a common product that can be purchased, and its specific structure is not described in detail. Example 2

[0037] See also Figure 10 As shown, the present embodiment discloses an outdoor 5G base station natural cooling cabinet. Preferably, in order to realize automatic control of heat dissipation, a controller 12 and a temperature detection sensor 11 are provided in the cabinet 1. The temperature detection sensor 11, the exhaust fan 10, the air filter 6 and the heat dissipation fan 5 are all electrically connected to the controller 12. By setting the temperature detection sensor 11, the internal temperature of the cabinet 1 is detected in real time. Once the temperature is greater than the preset temperature, the controller 12 controls the exhaust fan 10, the air filter 6 and the heat dissipation fan 5 to work, and the external air is sucked in from the air inlet, filtered through the air filter 6, and blown into the cabinet 1 by the heat dissipation fan 5. After the interior of the cabinet 1 is cooled, it is discharged through the exhaust fan 10, thereby realizing the automatic heat dissipation function. It should be noted that the specific models of the controller 12 and the temperature detection sensor 11 belong to the conventional technology in this field, so they are not described in detail.

[0038] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
