Detailed Description

The invention is described in detail below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a cabinet 100 according to an embodiment of the present application includes an equipment cabinet 10 and an air-conditioning cabinet 20, and the equipment cabinet 10 and the air-conditioning cabinet 20 are combined to form the cabinet. A plurality of devices 11 are installed in the device cabinet 10; the air conditioner 30 is installed in the air conditioning cabinet 20 to supply cool air to the equipment 11 in the equipment cabinet 10, thereby achieving the purpose of heat dissipation.

The cabinet of this application can be applicable to the heat dissipation demand of outdoor cabinet in basic station. In other embodiments, the cabinet of the present application may also be used indoors.

Typically, the equipment cabinet 10 and the air conditioning cabinet 20 are each in the shape of a cube.

The equipment cabinet 10 includes an equipment cabinet body 13 substantially in the form of a frame. The front side of the equipment cabinet body 13 is provided with an equipment cabinet front door 14, and the internal structure of the equipment cabinet 10 can be exposed by opening the front door, so that the equipment 11 can be conveniently dismounted and maintained.

With particular reference to fig. 3, a plurality of devices 11 may be mounted in a vertical arrangement within the device cabinet 13. Usually, the device 11 with large heat generation amount is provided with an air duct, or a ventilation gap can be reserved between adjacent devices 11 to allow air to circulate and dissipate heat. The ventilation duct and the ventilation gap of the equipment area are collectively referred to as a heat dissipation area 16 in the present application.

Inside the apparatus cabinet 10, there is a space between the outer periphery of the apparatus 11 and the apparatus cabinet 13, specifically, a space is formed between the periphery of the apparatus 11 and the inner wall of the apparatus cabinet 13, the space forming the heat dissipation passage 12. The heat dissipation channel 12 communicates with the heat dissipation area 16 to allow air to circulate between the heat dissipation channel 12 and the heat dissipation area 16.

Referring to fig. 4, 5, the air conditioning cabinet 20 includes an air conditioning cabinet body 21 substantially in the form of a frame, and an air conditioner 30 mounted inside the air conditioning cabinet body 21.

The indoor return air inlet 312 and the indoor supply air outlet 311 of the air conditioner 30 are communicated with the heat dissipation path 12 (described in detail below) to circulate and supply cool air into the heat dissipation path 12, and the cool air in the heat dissipation path 12 can flow to the heat dissipation area 16 to contact the equipment 11, thereby taking away heat from the equipment 11.

In other embodiments, front and rear doors may be provided on the equipment cabinet 10 and/or the air conditioning cabinet 20.

According to some embodiments of the present application, the air conditioning cabinet 20 and the equipment cabinet 10 can be flexibly configured and combined according to the use condition and the refrigerating capacity.

Illustratively, the air-conditioning cabinets 20 may be flexibly combined on one or both sides of the equipment cabinets 10, targeting a single equipment cabinet 10. When the heating value of the equipment cabinet 10 is relatively large and the refrigerating capacity of one air-conditioning cabinet 20 cannot meet the heat dissipation requirement, one air-conditioning cabinet 20 may be respectively arranged on the left side and the right side of the equipment cabinet 10, and the two air-conditioning cabinets 20 simultaneously provide cold air to the middle equipment cabinet 10; when the heat productivity of the equipment cabinet 10 is not large and the cooling capacity of one air-conditioning cabinet 20 can meet the heat dissipation requirement, one air-conditioning cabinet 20 may be disposed on the left side or the right side of the equipment cabinet 10.

The structural style that the air conditioner cabinet 20 of this application can dispose in a flexible way, because equipment cabinet 10 and air conditioner cabinet 20 are mutually independent module, so do not have any influence to the structure of equipment cabinet 10, avoided among the correlation technique need add circulating fan in the inside of equipment cabinet 10 and prolong cold volume transmission and occupy the problem of equipment cabinet 10 inner space.

The flexible cabinet combination form of the air conditioner cabinet 20 and the equipment cabinet 10 in the application can meet the heat dissipation requirements of capacity expansion and heat productivity increase of later-stage equipment.

The communication equipment at the earlier stage of the cabinet is less, the heat productivity is small, and the heat dissipation requirement of the equipment can be met by a small number of air conditioners; with the increase of communication equipment and business volume in the later period, only the air conditioner cabinet 20 needs to be added on the cabinet, elimination and updating are not needed, and the investment cost in the later period is low.

Therefore, the air conditioning cabinet 20 of the present application can implement the modularized capacity expansion, and solve the problem in the related art that the capacity expansion cannot be performed with the increase of the number of devices and the heat productivity.

In some embodiments of the present application, the air conditioning cabinet 20 and the equipment cabinet 10 have the same width and height dimensions, and the two can be flexibly and transversely spliced, and have the advantages of wide application range and high degree of generalization. In other embodiments, the air conditioning cabinet 20 and the equipment cabinet 10 may have the same dimensions in the length, width, and height directions, so that the air conditioning cabinet 20 and the equipment cabinet 10 may be interchanged, i.e., the equipment cabinet may be installed inside the air conditioning cabinet, or the air conditioning cabinet may be installed inside the equipment cabinet, thereby improving the versatility and the overall uniformity of the various parts of the cabinet.

In some embodiments of the present application, referring specifically to fig. 4, a single independent air conditioner 30 may be disposed in the air conditioning cabinet 20, and the power of the independent air conditioner is relatively large, and the cooling capacity per unit time is also relatively large, so that the heat dissipation requirement of the equipment cabinet 10 can be satisfied in a short time.

In other embodiments of the present application, and with particular reference to FIG. 5, a plurality of air conditioners 30 may be disposed within the air conditioning cabinet 20. The air conditioner 30 is installed in the air conditioning cabinet 20 as individual modules, and the volume and power of the modular air conditioner are smaller than those of the independent air conditioner.

The modular installation of the air conditioner 30 allows for the targeted dissipation of localized hot spots within the equipment cabinet 10.

Specifically, a plurality of layers of racks are arranged in the air-conditioning cabinet 20, and the air conditioner 30 can be flexibly placed on any rack, so that the air conditioner 30 can be correspondingly installed in the air-conditioning cabinet 20 for fixed-point refrigeration and heat dissipation according to the position of a local hot spot in the equipment cabinet 10, and the waste of cooling capacity of a single independent air conditioner is avoided.

For example, when the heat generation amount in the middle of the equipment cabinet 10 is large, the air conditioner 30 may be disposed at a position in the air conditioner cabinet 20 that generates heat in a transverse direction, and the air conditioner 30 cools and dissipates heat directly to a hot spot in the middle of the equipment cabinet 10. Because the air conditioner is close to the heating point, the distance of cold transmission is short, the utilization rate of cold is high, and the cooling and radiating effects are improved.

The number of the air conditioners 30 can be flexibly increased or reduced in the air conditioner cabinet 20 in a plurality of modularized air conditioners 30 forms, the heat dissipation requirements of different numbers and heating devices are met, and the capacity expansion of the cooling capacity in the air conditioner cabinet 20 is realized.

In the early stage of base station construction, the number of the devices 11 in the device cabinet 10 is small, the heat productivity is small, a small number of air conditioners 30 can meet the heat dissipation requirement of the devices, and the investment cost is low; as the amount of post-stage equipment and traffic increases, only the required number of air conditioners 30 need to be added to the air conditioning cabinet 20.

In some embodiments of the present application, referring to fig. 6, 7, the heat dissipation channel 12 includes a cold channel 121 and a hot channel 122. A cold channel 121 is formed between the rear end of the equipment 11 and the rear wall of the equipment cabinet 13; a hot aisle 122 is formed between the front end of the equipment 11 and the front wall of the equipment cabinet 13.

An indoor return air inlet 312 of the air conditioner 30 is communicated with the hot channel 122, and an indoor air supply outlet 311 of the air conditioner 30 is communicated with the cold channel 121; the hot air in the equipment cabinet 10 is collected into the indoor air return opening 312, and is heat-exchanged into cold air in the air conditioner 30, and the cold air is blown to the cold channel 121 through the indoor air supply opening 311, and the cold air further passes through the heat dissipation area 16 of the equipment 11 to become hot air, and flows into the hot channel 122, so that the refrigeration and heat dissipation cycle of the equipment cabinet 10 by the air conditioner cabinet 20 is realized.

Because the frequency of opening the qianmen is relatively more, this application can avoid opening the loss of cold volume when the qianmen with cold passageway 121 setting at equipment cabinet 10's rear portion, has improved cold volume utilization ratio, has the even reasonable, the good advantage of radiating effect of air current organization in the cabinet.

According to some embodiments of the present application, the indoor return air opening 312 of the air conditioner 30 is located at a front portion of a side thereof, in opposite communication with the hot aisle 122; the indoor blowing port 311 of the air conditioner 30 is located at the rear of the side thereof, opposite to the cold aisle 121. Thus, the indoor air supply outlet 311 is closer to the cold channel 121, and the indoor air return outlet 312 is closer to the hot channel 122, so that the transmission distance can be shortened as much as possible, and the air flow circulation efficiency can be improved.

In some embodiments of the present application, the air conditioner 30 may be a two-body air conditioner in which an outdoor unit and an indoor unit are separately connected, and the indoor unit is installed in the air conditioning cabinet 20 to cool and dissipate heat of the equipment cabinet 10.

In other embodiments of the present application, the air conditioner 30 is an all-in-one machine. When the indoor unit of the two-body air conditioner is disassembled and assembled in the air-conditioning cabinet 20, the indoor unit and the outdoor unit are connected through a system pipeline, the indoor unit is limited by the outdoor unit when moving, the disassembly and the assembly are not convenient enough, the integral air conditioner is adopted, the disassembly and the assembly are convenient, the position change is more flexible, and the operations of field installation, pipe connection, evacuation, fluorine injection and the like are avoided.

Referring to fig. 8 and 9, the air conditioner 30 may include a case 31, an indoor unit 32, and an outdoor unit 33.

The casing 31 has a substantially rectangular parallelepiped box shape, and forms the entire appearance of the air conditioner 30. An indoor air supply outlet 311 is formed at the rear of the casing 31, an indoor air return inlet 312 is formed at the front of the casing 31, an evaporation air duct 323 is formed between the indoor air supply outlet 311 and the indoor air return inlet 312, and the indoor unit 32 is installed in the evaporation air duct 323.

The indoor air supply outlet 311 is disposed at the left side and/or the right side of the rear portion of the housing 31, so that heat dissipation to the horizontal device 11 can be concentrated, and cold air is prevented from being too dispersed when the indoor air supply outlet 311 has multiple directions.

The indoor return air opening 312 may be provided at the left and/or right side of the front of the case 31; alternatively, the indoor return air opening 312 may be provided at the left and/or right side of the rear portion of the casing 31, and the top surface, so that the air conditioner 30 can perform side and top return air to increase the return air area when there is no shelter on the top surface of the air conditioner 30 (for example, the air conditioner 30 located at the top of the air conditioner cabinet 20, or the air conditioner 30 located at the middle or lower portion does not have another air conditioner 30 on its upper rack).

The indoor unit 32 may include an indoor fan 321, an evaporator 322, system piping, and the like. The indoor fan 321 is used for promoting the air flow to circulate between the equipment cabinet 10 and the evaporation air duct 323 of the air conditioner 30; the evaporator 322 is used to cool the airflow and reduce the temperature inside the equipment cabinet 10; the system piping is used to realize the connection between the indoor unit 32 and the outdoor unit 33.

When the air conditioner 30 is in operation, under the forced flow action of the indoor fan 321, the hot air in the equipment cabinet 10 enters the evaporation air duct 323 of the air conditioner 30 through the indoor air return opening 312, and after the heat exchange between the evaporation air duct 323 and the evaporator 322 is performed to generate cold air, the cold air is sent back to the equipment cabinet 10 from the indoor air supply opening 311.

The evaporator 322 is vertically arranged in the evaporation air duct 323, and slightly inclines relative to the air flow direction to increase the area of the evaporator 322, increase the heat exchange amount and improve the heat exchange efficiency.

The outdoor unit 33 may be front-inlet and rear-outlet air, or front-outlet and rear-inlet air. For example, when the air conditioner 30 is operated with front air intake and rear air outtake, under the forced flow action of the outdoor fan 332, the air at the front side enters the condensing air duct 334 to exchange heat with the condenser 333, and then flows out from the rear side.

In some embodiments of the present application, the indoor unit 32 and the outdoor unit 33 are spaced apart from each other within the housing 31. Specifically, a transverse middle partition 315 is provided at the middle portion of the casing 31 to divide the inner space of the casing 31 into upper and lower spaces, the indoor unit 32 is provided in the upper space, and the outdoor unit 33 is provided in the lower space. Since the outdoor unit 33 is heavy, the stability of the entire air conditioner 30 can be secured by disposing the outdoor unit 33 at the lower portion.

The air flow organization of the indoor unit 32 and the outdoor unit 33 is completely isolated, the problem of return air short circuit is avoided, and the utilization rate of the air conditioning cold quantity is high.

The air conditioner adopts a 48V direct current variable frequency design, and can dynamically adjust output cold quantity according to the heat productivity of equipment in the cabinet.

The storage battery pack is arranged on the cabinet, so that the storage battery can be used for supplying power to the air conditioner to operate when the mains supply is powered off, and low-risk downtime of equipment in the cabinet is guaranteed.
