Description

Special rack of 5GBBU

Technical Field

The utility model belongs to the technical field of communication network equipment, especially, relate to a special rack of 5 GBBU.

Background

The common cabinet is only a simple communication device for placing BBUs, PTNs, switching power supplies and the like, and the main function is to enable the devices to be orderly placed and fixed in the cabinet. And then, a fixing device for the power plug and the wiring harness is provided. Some are also equipped with small-size fan for the heat dissipation, but receive structural constraint heat dissipation ability weak, the heat dissipation of equipment mainly leans on the air conditioner in the computer lab.

Various communication equipment has different heat dissipation channel directions due to different manufacturers. Because the internal space of a common cabinet is limited, hot air of one device often enters the air inlet of the heat dissipation channel of the other device, the heat dissipation direction is disordered, local high temperature inside the cabinet and the device is formed, and then higher cooling requirements are provided for a machine room air conditioner, and huge energy waste is caused. Therefore, in order to not influence heat dissipation, communication equipment such as a small number of BBUs can be only installed in the common cabinet, and utilization of the cabinet is seriously influenced.

For example, chinese patent publication No. CN102984899A discloses a cabinet and a communication device having the same. The cabinet comprises a framework component and a covering component which is assembled on the framework component and surrounds to form a hollow cavity; the skeleton assembly comprises a stand column; the covering assembly comprises a wallboard, a door body, a base and a top cover, one end of the upright post is connected to the base, and the top cover is connected to the other end of the upright post; the wallboard joint in the stand, the door body rotate connect in skeleton subassembly or rotate connect in cover the subassembly. This rack has the heat dissipation direction confusion, influences the radiating efficiency's problem.

Because of the high power density of 5G communication equipment, the energy consumption of the equipment such as BBU is 3-5 times that of 4G similar equipment, and if the existing common cabinet is used, the heat dissipation defect is more obvious.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned problem that prior art exists, the utility model provides a special rack of 5GBBU for communication equipment's heat dissipation direction in the rack is unanimous, can not make the confusion of hot air-out and the cold air inlet of heat dissipation, has greatly practiced thrift the energy consumption of computer lab air conditioner.

The technical scheme of the utility model as follows:

a special cabinet for a 5GBBU comprises a base, wherein outer stand columns are fixed on four corners of the base, a top cover is arranged above each outer stand column, inner stand columns are correspondingly arranged on the base at positions close to each outer stand column, mounting holes for mounting BBU equipment and inner sealing plates are formed in the inner stand columns, and the inner sealing plates are arranged between adjacent BBU equipment;

a left sealing plate, a right sealing plate, a front sealing plate and a rear sealing plate which are movably fixed are arranged between the outer stand columns, and the front sealing plate and the rear sealing plate are provided with ventilation openings; the vertical sealing plates are arranged between two of the outer stand columns positioned at the oblique opposite angles of the base and the inner stand columns close to the outer stand columns, and the inner stand columns are respectively provided with a lower sealing plate and an upper sealing plate at the positions close to the base and the top cover.

The utility model discloses a be provided with the upright shrouding between wherein two outer stands of base diagonal angle and the inner column that is close to gaseous flow direction has been controlled. When the air inlet of BBU equipment was when the left side, right front side, set up on the outer column of left rear side and its inner column that is close to and found the shrouding, the rack is at the during operation, and air conditioning gets into from the vent of preceding shrouding, shunts to the left side, and the effect of breathing in of rethread BBU equipment gets into BBU inside and takes away the heat from the left air inlet of BBU equipment, and the vent that the gas outlet exhaust heat from BBU equipment right side and rear side finally converged the back shrouding is discharged. The vertical sealing plate plays a role in guiding flow and prevents cold air and hot air from flowing randomly.

When the air inlet of BBU equipment was on the right side, at the left front side, set up on the outer column of right rear side and its inner column that is close to and found the shrouding, the rack is at the during operation, and air conditioning gets into from the vent of preceding shrouding, shunts to the right side, and the effect of breathing in of rethread BBU equipment gets into BBU inside and takes away the heat from the air inlet on BBU equipment right side, and the vent that the gas outlet discharged heat from BBU equipment left side and rear side finally converged the back shrouding is discharged.

Because the number of the BBU equipment installed in the cabinet is determined by actual requirements, when the number of the installed BBUs is small, more space is left in the middle, and in order to improve the heat dissipation of each BBU equipment more pertinently, preferably, an air duct box is arranged at the upper part or the lower part of each BBU equipment, one side of the air duct box close to the air inlet of the side surface of the BBU equipment is hollowed out and fixedly provided with a switching shell, and the switching shell is communicated with the air inlet of the side part of the BBU equipment; the side wall of wind channel box doubles as interior shrouding, wherein, is equipped with the air inlet screen cloth near the anterior lateral wall of BBU equipment.

When the BBU devices installed in the cabinet are few, each BBU device can achieve a good heat dissipation effect.

In order to make the heat dissipation air current concentrate more, avoid air conditioning to get into from the equidirectional not to cause the air current disorder and influence the heat dissipation, be close to and all be equipped with upright shrouding between two outer stands of BBU equipment front portion and the inner column that corresponds. The vertical sealing plate isolates air communication between the air inlet of the front sealing plate and the air outlet side of the BBU equipment.

In order to further increase the radiating effect, the top cap be equipped with the screen cloth respectively in the position that is close to preceding shrouding, left shrouding and right shrouding. Air conditioning can also get into the rack from the screen cloth that the top cap is close to preceding shrouding and left shrouding position, and ultimate steam can also be discharged from the screen cloth that the top cap is close to right shrouding position to heat transfer effect has been increased.

In order to increase the structural strength of the inner column, the outer column and the stand columns, a plurality of cross beams are arranged between the outer column and are arranged at the positions close to the bottom and the top of the cabinet.

Further, the plurality of cross beams are arranged between the outer stand columns for fixing the left sealing plate and the right sealing plate.

And the two ends of the inner upright post are respectively connected with the bottom plate and the top cover through bolts or welding.

The left sealing plate, the right sealing plate, the front sealing plate and the rear sealing plate are movably fixed with the outer stand column by adopting a single-door or split-door structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a shrouding and upright shrouding in setting up cut apart into cold, hot district with rack inside, realize admitting air and carminative cold and hot passageway separation, have improved the radiating efficiency, are particularly suitable for the heat dissipation of high-power 5G equipment.

2. The utility model discloses an air duct box that matches has been installed to every BBU equipment for air current between the different BBU equipment is conflict, and each BBU equipment all can reach better radiating effect.
