Description

5G base station air conditioner

The technical field is as follows:

the utility model relates to a 5G basic station technical field, in particular to 5G basic station air conditioner.

The background art comprises the following steps:

the 5G basic station rack is because of waterproof, dustproof, protection against insects requirement, the rack is almost totally closed, but equipment is more in the rack, there are power equipment, communications facilities, backup battery etc., these equipment can produce a large amount of heats, lead to the rack temperature to rise, in order to guarantee that equipment normally works, generally all need install the air conditioner on the rack, every rack all is according to one set of air conditioning system, these air conditioning systems generally all are civilian fixed frequency air conditioner, the refrigerating capacity is not enough, and to pair rack, trigeminy rack, dispose many sets of air conditioning system, consume the energy, and the overall quality is overweight.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

The utility model has the following contents:

in order to achieve the above purpose of the prior art, the utility model provides a 5G base station air conditioner, which comprises a compressor and a condenser communicated with the compressor; the air conditioner also comprises at least 2 groups of cold air units communicated with the compressor; the cold air unit comprises an evaporator, an expansion valve arranged on the evaporator and a fan arranged on the back of the evaporator; the medium of the compressor enters the evaporator after passing through the expansion valve; the evaporator is communicated with the condenser.

Further, the evaporator also comprises a pair of temperature sensors, an electromagnetic expansion valve and a controller which are arranged on the upper side and the lower side of the front surface of the evaporator; the electromagnetic expansion valve is arranged at the communication position of the compressor and the cold air unit and used for adjusting the flow of the medium of the compressor entering the cold air unit; the controller is connected with the temperature sensor; the controller is connected with the electromagnetic expansion valve.

Further, the cold air units are 4 groups at most.

Compared with the prior art, the utility model discloses a 5G basic station air conditioner sets up two at least cold wind units of group, uses a compressor, cools down to the multimachine cabinet, has the energy can be saved, reduces the advantage of total weight. Furthermore, an electromagnetic expansion valve is arranged and used for adjusting the medium flow of the cold air unit, so that the multi-machine cabinet is cooled uniformly, and the multi-machine cabinet cooling system has the advantage of further saving energy.

Description of the drawings:

fig. 1 is a front schematic view of a 5G base station air conditioner of the present invention;

fig. 2 is a schematic left-side perspective view of a 5G base station air conditioner according to the present invention;

fig. 3 is a schematic right-side perspective view of a 5G base station air conditioner according to the present invention;

the reference signs are: 1-compressor, 2-evaporator, 3-condenser, 4-fan, 5-electromagnetic expansion valve, 6-expansion valve, 7-controller, 8-temperature controller.

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention is provided, but it should be understood that the scope of the present invention is not limited by the embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 1 to 3, the present invention relates to a 5G base station air conditioner; the refrigeration system comprises a compressor 1 and a condenser 3, wherein the condenser 3 is communicated with the compressor 1, a liquefied medium of the condenser 3 flows back to the compressor, a corresponding number of cold air units are arranged according to the number of cabinets, for example, a duplex cabinet is provided, two groups of cold air units and a triplex cabinet are provided, three groups of cold air units are arranged, according to practical experience, at most four groups can be arranged, because too many groups are arranged, the power of the compressor 1 is limited, the refrigeration effect of each group of cold air units is poor, and each group of cold air units comprises an evaporator 2, an expansion valve 6 arranged on the evaporator 2 and a fan 4 arranged on the back of the evaporator 2; the high-pressure medium of the compressor 1 is decompressed and atomized after passing through the expansion valve 6, enters the evaporator 2, communicates the evaporator 2 with the condenser 3, and flows through the evaporator 2, enters the condenser 3, and is liquefied in the condenser 3.

In order to ensure the temperature consistency of each cold air unit and dynamically distribute media flowing into the cold air unit, each cold air unit is provided with a pair of temperature sensors 8 which are positioned at the upper side and the lower side of the front surface of the evaporator 2, an electromagnetic expansion valve 5 and a controller 7 are also arranged, the electromagnetic expansion valve 5 is arranged at the communication part of the compressor 1 and the cold air unit, the flow rate of the media entering the cold air unit of the compressor 1 is adjusted, the controller 7 is connected with the temperature sensors 8 to obtain temperature data collected by the temperature sensors 8, the controller 7 is connected with the electromagnetic expansion valve 5, and the controller 7 converts the temperature data into temperature data required by the electromagnetic expansion valves and sends the temperature data to the electromagnetic expansion valves 5.

The specific working principle is as follows: the temperature sensor of each cold wind unit gathers the temperature (correspond the rack temperature promptly), the controller acquires each temperature sensor's temperature and converts into the required temperature data of electromagnetic expansion valve and gives electromagnetic expansion valve, the medium flow that the compressor got into the evaporimeter of each cold wind unit is adjusted to the electromagnetic expansion valve, compressor high pressure cooling medium gets into the expansion valve, can atomize after the decompression, atomizing medium gets into the evaporimeter, the air can be cooled off around the evaporimeter, the fan at the evaporimeter back blows away the cold air in every side, cool down the rack, the medium gets into the condenser from the evaporimeter, liquefied in the condenser, the liquefied medium gets into the compressor again, so circulation.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
