Embodiment 1

[0028] like figure 1 , figure 2 and image 3As shown, a BBU vertical installation cabinet with good heat dissipation effect includes an outer cabinet 1, a fixing frame 2 and several sub cabinets 3, the fixing frame 2 is arranged in the outer cabinet 1, and several sub cabinets 3 are arranged up and down in order and are fixed with the fixing frame 2 , the sub-cabinet 3 and the fixing frame 2 divide the internal space of the outer cabinet 1 into an air inlet cavity 1.1 and an air outlet cavity 1.2; the lower part of the sub-cabinet 3 is provided with an air inlet 3.1, and the air inlet 3.1 faces the air inlet cavity 1.1. The upper part of 3 is provided with an air outlet 3.2, and the air outlet 3.2 faces the air outlet cavity 1.2. Below the air inlet 3.1 is an air intake guide plate 3.3 arranged obliquely. The air outlet guide plate 3.4 is provided above the air outlet 3.2. The height of the air outlet guide plate 3.4 on the side close to the air inlet cavity 1.1 is lower t...

Embodiment 2

[0031] like Figure 4 As shown, on the basis of Embodiment 1, the side of the bottom sealing plate 5 close to the air inlet cavity 1.1 is hinged with the sub-cabinet 3, the hinge axis axis of the bottom sealing plate 5 is parallel to the arrangement direction of several mounting brackets 4, and the bottom The sealing plate 5 is provided with a spring for making the bottom sealing plate 5 close to the sub-cabinet 3, a lifting block 6 is arranged on the sub-cabinet 3, the lifting block 6 is slidably connected with the sub-cabinet 3, and the lower end of the lifting block 6 is connected to the bottom sealing plate 5. touch. The upper end of the lifting block 6 facing the air inlet cavity 1.1 is provided with a guiding slope 6.1.

[0032] In the above technical solution, the spring may be a telescopic spring or a torsion spring. If the BBU unit is not installed on the mounting bracket 4, the bottom sealing plate 5 presses the bottom of the mounting bracket 4 under the action of ...

Embodiment 3

[0034] like Figure 5 As shown, on the basis of Embodiment 1, one side of the bottom sealing plate 5 is hinged with the sub-cabinet 3, the hinge axis axis of the bottom sealing plate 5 is perpendicular to the arrangement direction of several mounting brackets 4, and the bottom sealing plate 5 is provided with There is a spring for making the bottom sealing plate 5 close to the sub-cabinet 3 . The sub-cabinet 3 is provided with a lifting block 6 , and the lower end of the lifting block 6 is in contact with the bottom sealing plate 5 . The upper end of the lifting block 6 facing the air inlet cavity 1.1 is provided with a guiding slope 6.1.

[0035] In the above technical solution, the spring may be a telescopic spring or a torsion spring. If the BBU unit is not installed on the mounting bracket 4, the bottom sealing plate 5 presses the bottom of the mounting bracket 4 under the action of the spring to make the bottom of the mounting bracket 4 airtight, so as to prevent cold ai...

Abstract

The invention discloses a BBU vertical installation cabinet with good heat dissipation effect, which includes an outer cabinet, a fixing frame and several sub-cabinets. The fixing frame is arranged in the outer cabinet, and the several sub-cabinets are arranged up and down and fixed with the fixing frame. The sub-cabinet and the fixing frame The inner space of the outer cabinet is divided into an air inlet cavity and an air outlet cavity; an air inlet is arranged below the sub-cabinet, and the air inlet faces the air inlet cavity, and the upper part of the sub-cabinet is provided with an air outlet, and the air outlet faces the air outlet cavity. The invention provides a BBU vertical installation cabinet with good heat dissipation effect, so that the equipment in the sub cabinets at various positions in the vertical installation cabinet can fully dissipate heat.

Description

technical field [0001] The invention relates to the technical field of BBU vertical installation cabinets, in particular to a BBU vertical installation cabinet with good heat dissipation effect. Background technique [0002] The LTE era of wireless communication has fully opened. With the gradual approach of 5G, the bandwidth of a single base station will increase significantly, the deployment density of base stations will increase, and the existing network construction methods of base stations have shown some problems. For example, the site selection of base stations is difficult, the cost of the equipment room is high, the utilization rate of base station resources is low, and the maintenance workload is large. With the separation of the (building base band unit, BBU) baseband processing unit and the (Radio Remote Unit, RRU) remote radio unit and the gradual maturity of the RRU remote technology, the future 5G will also adopt the BBU centralized deployment solution. The ...
