In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

At present, the wireless base station mainly adopts air cooling technologies such as an industrial air conditioner and the like to refrigerate, but the PUE value is generally higher due to high energy consumption of air conditioning equipment. Along with the continuous deep layout of 5G communication, the number of 5G base stations is increased, the density of the base stations exceeds the current scale by 4 times, and the heat dissipation requirement is increased, so that the current air cooling mode has obviously failed to meet the heat dissipation requirement of high power density due to the low air heat exchange coefficient and the low cooling or heat dissipation speed.

The traditional air-cooled rack type BBU (baseband processing unit) equipment occupies a large space of a machine room, the effective utilization space proportion of the cabinet is low, for example, a 1200 x 660 x 510mm cabinet can only deploy 5-6 BBU equipment, and the operation is complex, difficult to expand and maintain and high in operation and maintenance cost.

In addition, the optical module of the existing BBU equipment works for a long time and generates larger heat, in the existing air-cooled rack type deployment, the surface temperature of the optical module can generally reach about 60-70 ℃, the optical module works for a long time and at a high temperature, dust in the air is easy to attach to the surface of the module, and the conditions of oxidization, static electricity and the like are caused, so that the optical module is easy to damage, and the service life is influenced.

In view of this, this embodiment provides a BBU cooling apparatus and cooling cabinet, can solve the unable heat dissipation demand that satisfies BBU equipment of current industry air conditioner etc. air-cooling technique, and the occupation space of BBU cooling apparatus and the problem that the optical module of BBU equipment is fragile, and the detailed description is described below respectively.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4 together, fig. 1 is a schematic structural diagram of an embodiment of a BBU cooling apparatus according to the present utility model, fig. 2 is a schematic structural diagram of an embodiment of a cabinet according to the present utility model, fig. 3 is a schematic semi-sectional structural diagram of fig. 2 and fig. 4 is a schematic structural diagram of an embodiment of a shunt according to the present utility model.

In one embodiment, the BBU cooling device is a device that utilizes a circulating coolant to dissipate heat from the BBU device.

The BBU cooling apparatus may include a housing 10. The machine body 10 is used as a basic carrier of the BBU cooling equipment and plays a role in bearing and protecting other parts of the BBU cooling equipment.

The BBU cooling apparatus also includes a cabinet 20. The cabinet 20 is installed in the machine body 10, and the cabinet 20 has a receiving space 21, an inlet 22 and an outlet 23. When the cooling liquid circulates and enters the accommodating space 21 through the inlet 22 and is discharged through the outlet 23, the cooling liquid can take away heat generated by the BBU equipment, and the cooling liquid exchanges heat with the BBU equipment, so that the higher heat dissipation requirement of the BBU equipment can be met. Meanwhile, the BBU equipment adopts liquid cooling heat dissipation, so that the installation gap between two adjacent BBU equipment can be reduced. Compared with the traditional air cooling heat dissipation mode, the BBU cooling device of the embodiment can be used for arranging more BBU devices in a certain space, improving the accommodation amount, or reducing the occupation volume of the BBU cooling device under the condition of arranging the same quantity of BBU devices. In addition, as the BBU equipment is fully immersed in the accommodating space 21, the optical module of the BBU equipment can completely isolate air, so that dust, oxidation, corrosion and static electricity are effectively avoided, the failure rate of the optical module is reduced, and the service life of the optical module is prolonged.

The BBU cooling apparatus may also include a splitter 30. The flow divider 30 is configured to be installed in the accommodating space 21, divide the accommodating space 21 into a flow dividing space 211 and an installation space 212, and the flow inlet 22 is communicated with the flow dividing space 211, and the flow outlet 23 is communicated with the installation space 212. Specifically, the splitter 30 is formed with a plurality of through holes 31, and the plurality of through holes 31 are arranged in a preset arrangement manner, so that the cooling liquid entering the splitting space 211 through the inlet 22 flows to the installation space 212 after being split by the plurality of through holes 31, so as to perform liquid cooling heat exchange on the BBU equipment in the installation space 212.

It should be noted that, in the embodiment of the present utility model, the shunt member 30 is installed in the accommodating space 21, and a plurality of through holes 31 are formed on the shunt member 30. The flow divider 30 also divides the cooling liquid entering through the inlet 22 to the installation space 212 by utilizing the through holes 31, prevents the cooling liquid from concentrating on one point, ensures the stability of the temperature field in the installation space 212, eliminates the situations that the local hot spot and the local temperature in the installation space 212 are high or low, avoids uneven heat dissipation between BBU devices in the installation space 212, and improves the heat dissipation effect of the cooling liquid on each BBU device.

The splitter 30 may be vertically installed in the accommodating space 21, and the splitter 30 extends along the length direction of the cabinet 20, and correspondingly, the BBU devices in the installation space 212 may be disposed side by side along the length direction of the cabinet 20.

The preset arrangement mode may be rectangular arrangement, linear arrangement, spiral arrangement or the like. In order to better improve the heat dissipation uniformity of the cooling liquid to each BBU device, in an embodiment, the preset arrangement manner may be: the through holes 31 are arranged in at least two rows of flow areas 32, and the through holes 31 in each flow area 32 are vertically spaced.

In this embodiment, at each flow area 32 can be used to install at least one BBU device. Taking one BBU device installed at each flow region 32 as an example, when one of the flow regions 32 is installed, the cooling liquid flowing out of the plurality of through holes 31 in the flow region 32 mainly flows through the BBU device for heat dissipation of the BBU device. In general, in BBU cooling equipment, the coolant liquid can be through every flow area 32 water conservancy diversion, and the water conservancy diversion is carried out the heat transfer to corresponding BBU equipment respectively to solve a plurality of BBU equipment uneven heat dissipation, influence the problem of radiating effect.

Whereas in everyday use not every BBU cooling device is fully loaded, there may be a partial flow area 32 in the BBU cooling device where no BBU device is installed. In view of this, in an embodiment, when no BBU device is installed at the flow area 32, the plurality of through holes 31 in the flow area 32 are filled with plugs for blocking the through holes 31 to prevent the coolant from flowing out of the flow area 32, without taking part in the waste caused by heat exchange.

In this embodiment, the plug may be a rubber plug, a screw, or the like. However, the rubber plug is easily pushed by the liquid pressure to be separated from the through hole 31, and the connection is unstable. The present utility model preferably employs screws, and correspondingly, the through holes 31 should be threaded holes, and plugs are screwed with the through holes 31.

In an embodiment, the split space 211 may be an enclosed space. Specifically, the flow dividing member 30 may be constructed in an inverted L shape, such that a closed space is formed around the flow dividing member 30 and the inner side wall of the case 11, so as to avoid the situation that a portion of the coolant is sprayed or gushed out from the top of the flow dividing space 211 due to the excessive pressure and flow of the coolant entering the flow dividing space 211 through the inlet 22.

In an embodiment, a baffle 40 may be further installed in the installation space 212, where the baffle 40 is disposed opposite to the splitter 30, and the baffle 40 divides the accommodating space 21 into an apparatus space 2121 and a liquid return space 2122. The top of the baffle 40 has a liquid return port 41 such that the equipment space 2121 communicates with the liquid return space 2122 through the liquid return port 41, and the liquid return space 2122 communicates with the outflow port 23. The equipment space 2121 communicates with the shunting space 211 through a plurality of through holes 31, and the equipment space 2121 is used for mounting BBU equipment.

In this way, the cooling liquid entering the cabinet 20 can be seen in the arrow direction shown in fig. 3, and first flows into the equipment space 2121 uniformly through the splitter 30 to exchange heat with the BBU equipment. Then, the temperature of the cooling liquid after heat exchange rises, and by utilizing the principle that the cooling liquid sinks and the hot liquid floats upwards, the cooling liquid with higher temperature can float upwards and flow into the liquid return space 2122 from the liquid return port 41, and finally is discharged through the outlet port 23. It can be seen that, in this embodiment, the liquid return port 41 is disposed at the top of the baffle 40, so that the cooling liquid with higher temperature and the cooling liquid with lower temperature after heat exchange can be separated, so that the cooling liquid with higher temperature is discharged, the cooling liquid with lower temperature remains for continuous heat exchange, and the cooling liquid entering the cabinet 20 is fully utilized, so that the heat exchange effect is further improved.

In one embodiment, the body 10 includes a case 11 and a case cover 12. The top of the case 11 has a first opening 111, and a cover 12 is provided on the top of the case 11 to be openable and closable, the cover 12 being used to open and close the first opening 111. The cabinet 20 is mounted in the housing 11, and the cabinet 20 has a second opening 24, so that when the cover 12 opens the first opening 111, the BBU apparatus can be mounted into the cabinet 20 through the first opening 111 and the second opening 24 in sequence. When the first opening 111 is closed by the case cover 12, the cooling liquid in the case body 20 can be isolated from contacting with the external air, so as to reduce evaporation of the cooling liquid in the case body 20, and meanwhile, foreign matters outside can be prevented from entering the cooling liquid in the case body 20, so that the cleanliness of the cooling liquid is ensured.

In practical application, the cover 12 may be hinged to the case 11, and the cover 12 is turned to open and close the first opening 111. Of course, the machine body 10 may have an open structure, and the case cover 12 may be correspondingly hinged on the cabinet body 20, so that the case cover 12 may also cover the second opening 24, which is not limited in particular by the present utility model.

Referring to fig. 5 and 6, fig. 5 is a schematic view of a part of a structure of an embodiment of the BBU cooling apparatus according to the present utility model, and fig. 6 is a schematic view of an embodiment of a cooling system according to the present utility model.

In one embodiment, the BBU cooling apparatus further comprises a cooling system 50, the cooling system 50 being configured to communicate with the inlet 22 and the outlet 23 of the cabinet 20 to provide a circulating cooling fluid into the cabinet 20. In practical application, the cooling system 50 is installed in the box 11, and the cooling system 50 is located below the cabinet 20, that is, the cooling system 50 and the cabinet 20 adopt an upper-lower layered structure design, so that the internal space of the machine body 10 can be fully utilized, and the volume of the equipment can be reduced.

With respect to the specific structure of the cooling system 50. The cooling system 50 may include a feed line 51 and a return line 52. One end of the liquid inlet pipe 51 is communicated with the flow inlet 22, the other end of the liquid inlet pipe 51 is communicated with a liquid outlet of the external heat exchange device 60, and the cooling liquid subjected to heat exchange by the external heat exchange device 60 sequentially enters the cabinet body 20 through the liquid inlet pipe 51 and the flow inlet 22. One end of the liquid return pipe 52 is communicated with the outflow port 23, the other end of the liquid return pipe 52 is communicated with a liquid inlet of the external heat exchange device 60, and the cooling liquid discharged through the outflow port 23 enters the external heat exchange device 60 through the liquid return pipe 52 for heat exchange. It should be noted that the external heat exchange device 60 may be an air cooler, a liquid-liquid heat exchanger, a cooling tower, or the like, and the specific structure thereof may refer to the prior art.

It should be noted that the liquid return pipe 52 is connected in series with a first driving branch 521 and a second driving branch 522 which are connected in parallel with each other, wherein the first driving branch 521 and the second driving branch 522 are respectively connected in series with a circulating pump 523. In this way, the cabinet 20 and the external heat exchange device 60 may be connected in series through the liquid inlet pipe 51 and the liquid return pipe 52 to form a refrigeration circuit, and the circulation pump 523 provides a liquid driving force for the refrigeration circuit, so as to provide a low-temperature cooling liquid for the internal circulation of the cabinet 20. In addition, in this embodiment, two circulating pumps 523 connected in parallel are provided, and when a problem occurs in one circulating pump 523, the other circulating pump 523 can be switched to operate, so as to realize non-intermittent refrigeration.

Further, in the first driving branch 521, a hose 524 and an on-off valve 525 are connected in series at both front and rear ends of each circulation pump 523, and the hose 524 is located between the on-off valve 525 and the circulation pump 523. In the second driving branch 522, a hose 524 and an on-off valve 525 are connected in series at both front and rear ends of each circulation pump 523, and the hose 524 is located between the on-off valve 525 and the circulation pump 523. When the circulation pump 523 in the first driving branch 521 is operated, the switching valve 525 in the second driving branch 522 may be closed to prevent the coolant from entering the second driving branch 522.

When the circulation pump 523 in the first driving branch 521 is damaged, the switching valve 525 in the second driving branch 522 may be opened, and the circulation pump 523 in the second driving branch 522 may be opened, while the switching valve 525 in the first driving branch 521 is closed, to achieve switching. Thus, maintenance without shutdown can be realized, and the heat dissipation effect on BBU equipment in the machine body 10 is further ensured. Meanwhile, hoses 524 are respectively arranged at two ends of the circulating pump 523, and vibration generated during the operation of the circulating pump 523 is buffered by the hoses 524, so that the influence of the circulating pump 523 on the cooling system 50 is avoided.

Further, a check module 526 is further connected in series to the liquid return pipe 52, and the check module 526 is located between the first driving branch 521 and the second driving branch 522 and the external heat exchange device 60. When the circulation pump 523 suddenly stops, the check module 526 is configured to prevent the coolant in the liquid return pipeline 52 from flowing back to the circulation pump 523, thereby improving the service life of the circulation pump 523.

The fire-fighting gas cylinder 71 is connected with one end of the fire detection tube 72 through the container valve 73, the other end of the fire detection tube 72 is arranged around the first opening 111, and the other end of the fire detection tube 72 is used for monitoring whether open fire or overhigh temperature is generated in the machine body 10. If an open flame or an excessive temperature is generated in the machine body 10, the fire detecting tube 72 surrounding the first opening 111 will be fused, and the pressure in the fire detecting tube 72 will be lost. When the container valve 73 detects that the fire detecting pipe 72 loses pressure, the container valve 73 is opened, and the fire extinguishing gas in the fire extinguishing gas cylinder 71 is sprayed into the fire detecting pipe 72 through the container valve 73, so that the fire extinguishing gas is conveyed into the machine body 10 for extinguishing fire.

Further, the fire protection system also includes a status feedback line 74 and an alarm 75. An alarm 75 is connected to the reservoir valve 73 via a status feedback line 74. In practical application, the container valve 73 is internally provided with an electrical switch contact, and when the container valve 73 is opened, the electrical switch contact is closed, and the state feedback line 74 feeds back a signal to drive the alarm 75 to alarm.

Through the above mode, the fire-fighting gas cylinder 71 and the box 11 can be detachably connected by adopting the pipeline loose joint 76, so that the fire-fighting gas cylinder 71 and the machine body 10 can be separately carried in the carrying process, and then assembled after being carried to the destination address, thereby facilitating carrying operation and solving the problem that the fire-fighting gas cylinder 71 and the machine body 10 are inconvenient to carry together in the carrying process.

In one application scenario, the cooling cabinet may be independent of the BBU cooling apparatus. The cooling cabinet can be used alone as an integrated system. The cooling cabinet can also be assembled with the BBU cooling device in a detachable manner, and specifically, the cooling cabinet can be integrally assembled in the BBU cooling device or integrally disassembled from the BBU cooling device.

The cooling cabinet comprises at least a cabinet body 20 and a splitter 30. The cabinet 20 has a receiving space 21, an inlet 22 and an outlet 23.
