The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

As shown in fig. 1 and 2, fig. 1 is a schematic front view of an air conditioning system according to an embodiment of the present invention. Fig. 2 is a schematic top view of an air conditioning system according to an embodiment of the present invention. The air conditioning system according to the embodiment of the present invention includes a plurality of air conditioners 100, a plurality of communication devices 200, and a plurality of circulation members 300. A plurality of air conditioners 100 are arranged side by side, and each communication device 200 is provided between two adjacent air conditioners 100.

As shown in fig. 3 and 4, fig. 3 is a schematic view of an air conditioner 100 for a communication device according to a first embodiment of the present invention. Fig. 4 shows an exploded view of fig. 3. Note that, in order to show the internal structure, the outer wall of the cabinet in fig. 3 to 8 is subjected to a transparentization treatment.

The air conditioning device 100 for communication equipment of the present invention includes a cabinet 10, a plurality of outlet baffles 20, a plurality of return air baffles 30, a heat exchange unit 40, and a fan 50.

It is to be understood that the terms "comprises" and "comprising," as well as any variations thereof, in the embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or may alternatively include other steps or elements inherent to such process, method, article, or apparatus.

As an example, the cabinet 10 may be a generally rectangular parallelepiped structure and includes a top plate 155, a bottom plate 156, a first side plate 151, a second side plate 152, a third side plate 153, and a fourth side plate 154. The top plate 155 and the bottom plate 156 are oppositely disposed along the second direction D2. The first side plate 151 is connected to the top plate 155 and the bottom plate 156, the second side plate 152 is connected to the top plate 155 and the bottom plate 156, and the first side plate 151 and the second side plate 152 are oppositely disposed along the third direction D3. The third side plate 153 is connected to the top plate 155, the bottom plate 156, the first side plate 151, and the second side plate 152, the fourth side plate 154 is connected to the top plate 155, the bottom plate 156, the first side plate 151, and the second side plate 152, and the third side plate 153 and the fourth side plate 154 are oppositely disposed along the first direction D1. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other two by two.

Of course, in other embodiments, the cabinet 10 may have other shapes, which are not listed here.

The first side plate 151 and the second side plate 152 form the gas passage 101 therebetween. The first side plate 151 is provided with at least one first air outlet 102 and at least one first air return opening 103 corresponding to the first air outlet 102, the second side plate 152 is provided with at least one second air outlet 104 and at least one second air return opening 105 corresponding to the second air outlet 104, and the first air outlet 102, the first air return opening 103, the second air outlet 104 and the second air return opening 105 are all communicated with the air channel 101.

It is understood that the number of outlets (including the first outlet 102 and the second outlet 104) is the same as the number of return openings (including the first return opening 103 and the second return opening 105).

As an example, the first air outlet 102 is located at the bottom of the first side plate 151, and the first air return opening 103 is located at the top of the first side plate 151. The second air outlet 104 is located at the bottom of the second side plate 152, and the second air return 105 is located at the top of the second side plate 152. By arranging the air outlet at the bottom of the cabinet 10 and the air return inlet at the top of the cabinet 10, the air outlet and the air return inlet of the cabinet 10 can be adapted to the characteristics of lighter hot air and heavier cold air, so that the lighter hot air enters the cabinet 10 from the air return inlet at a higher position and the heavier cold air flows out of the cabinet 10 from the air outlet at a lower position.

As an example, the number of the first air outlet 102, the first air return opening 103, the second air outlet 104, and the second air return opening 105 is two. Along the first direction D1, the two first air outlets 102, the two second air outlets 104, the two first air returns 103, and the two second air returns 105 are all disposed at intervals, and a first placing area 141 is formed in an area between the two first air outlets 102 of the first side plate 151, and a second placing area 142 is formed in an area between the two second air outlets 104 of the second side plate 152.

The first placing area 141 of the first side plate 151 is used for placing the communication device 200, and the communication device 200 abuts against the first placing area 141. After the communication device 200 is placed in the first placement area 141, the cool air blown out from the two first air outlets 102 of the first side plate 151 can cool two opposite sides of the communication device 200, so as to solve the heat dissipation problem of the high-power communication device 200.

Similarly, the second placement region 142 of the second side panel 152 is used for placing another communication device 200, and the other communication device 200 abuts against the second placement region 142. After the communication device 200 is placed in the second placement area 142, the cool air blown out from the two second air outlets 104 of the second side plate 152 can cool two opposite sides of the communication device 200, so as to solve the heat dissipation problem of the high-power communication device 200.

Along the second direction D2, the first air outlet 102 corresponds to the first air return 103, and the second air outlet 104 corresponds to the second air return 105.

It is understood that the air outlets (including the first air outlet 102 and the second air outlet 104) may be rectangular, diamond-shaped, circular, etc. to meet the air supply requirements of different communication devices 200. The air return openings (including the first air return opening 103 and the second air return opening 105) can be rectangular, rhombic, circular, etc. to meet the air supply requirements of different communication devices 200.

In addition, the shape of the air outlet and the shape of the air return opening can be the same or different. The first outlet 102 and the second outlet 104 may be the same or different in shape. The shapes of the first air return opening 103 and the second air return opening 105 may be the same or different.

Of course, in other embodiments, the corresponding first air outlet 102 and the first air return opening 103 may also be arranged along a diagonal of the first side plate 151.

It can be understood that the number of the first air outlets 102 of the first side plate 151 may also be one, three or more than three. The number of the second air outlets 104 of the second side plate 152 may also be one, three or more.

The air outlet baffles 20 correspond to the first air outlet 102 and the second air outlet 104 in number, and are used for opening and closing the first air outlet 102 and the second air outlet 104. The plurality of return air baffles 30 correspond to the number of the first return air openings 103 and the second return air openings 105, and open and close the first return air openings 103 and the second return air openings 105.

That is, the number of the wind outlet baffles 20 is equal to the sum of the numbers of the first wind outlet 102 and the second wind outlet 104. Likewise, the number of return air baffles 30 is equal to the sum of the number of first return air openings 103 and second return air openings 105.

As an example, when the number of the first outlet ports 102, the number of the second outlet ports 104, the number of the first return air ports 103, and the number of the second return air ports 105 are two, the number of the outlet baffles 20 is four, and the number of the return air baffles 30 is four.

Of course, in other embodiments, the number of the wind outlet baffles 20 may also be less than the sum of the numbers of the first wind outlet 102 and the second wind outlet 104, for example, when the sum of the numbers of the first wind outlet 102 and the second wind outlet 104 is four, the number of the wind outlet baffles 20 may be one, two, or three. The number of return air baffles 30 may also be less than the sum of the number of first return air openings 103 and second return air openings 105, for example when the sum of the number of first return air openings 103 and second return air openings 105 is four, the number of return air baffles 30 may be one, two, or three.

The air conditioner 100 of the embodiment of the invention can adapt to the single-sided and/or double-sided cooling of the communication equipment 200 by selectively opening and closing different air outlets through the air outlet baffle 20 and selectively opening and closing different air return inlets through the air return baffle 30, and can adapt to the situation of double-sided and single-sided mixed cooling of the communication equipment 200, and the pPUE (Partial Power Usage efficiency, local electric energy utilization efficiency) can reach 1.15-1.2, and the energy-saving effect is obvious.

Specifically, when the communication device 200 is disposed only in the first placement area 141 of the first side plate 151 in the air conditioning apparatus 100 according to the embodiment of the present invention, and both sides of the communication device 200 need to be cooled, only the two first air outlets 102 and the two first air returns 103 need to be opened, and the air outlets and the air returns of the second side plate 152 need to be closed. When the single side of the communication device 200 needs to be cooled, only one first air outlet 102 and one first air return opening 103 of the first side plate 151 need to be opened, and the other air outlets and air return openings need to be closed.

When the first placement area 141 and the second placement area 142 of the air conditioner 100 according to the embodiment of the present invention are provided with the communication devices 200, the two first outlets 102, the two second outlets 104, the two first return-air inlets 103, and the two second return-air inlets 105 of the air conditioner 100 may be opened to cool both sides of each communication device 200. Of course, it is also possible to open only one first air outlet 102 and one first air return opening 103 corresponding to the first side plate 151, and open one second air outlet 104 and one second air outlet 104 corresponding to the second side plate 152, and close the remaining air outlets and air return openings, so as to cool the single side of each communication device 200.

It is understood that the manner of opening and closing the first outlet 102 and the second outlet 104 by the outlet baffle 20 can adopt various embodiments. For example, the air outlet baffle 20 may be fastened to the air outlet. When the air outlet needs to be closed, the air outlet baffle 20 is buckled with the air outlet. When the air outlet needs to be opened, the air outlet baffle 20 is moved away from the air outlet. The air outlet baffle 20 may be fastened to the air outlet by bolts, but not limited thereto.

Alternatively, the air outlet baffle 20 may be slidably connected with respect to the first side plate 151 and the second side plate 152. When the air outlet needs to be closed, the air outlet baffle 20 slides relative to the first side plate 151 and the second side plate 152, so that the air outlet baffle 20 covers the air outlet. When the air outlet needs to be opened, the air outlet baffle 20 slides away from the air outlet, so that the air outlet is exposed.

The manner of opening and closing the first return air opening 103 and the second return air opening 105 by the return air baffle 30 can refer to the manner of the outlet air baffle 20, and is not described herein again.

As shown in fig. 5 and 6, fig. 5 is a front view of an air conditioner 100 for a communication device according to a first embodiment of the present invention. Fig. 6 is a side view of the air conditioner 100 for communication equipment according to the first embodiment of the present invention. The heat exchange unit 40 is disposed in the cabinet 10 and is used for converting hot air into cold air. The fan 50 is disposed in the cabinet 10 and configured to drive the cool air to flow out from the first air outlet 102 and/or the second air outlet 104.

The heat exchange unit 40 may be regarded as an indoor unit of an air conditioner, and the heat exchange unit 40 is configured to convert hot air into cold air by being coupled with an outdoor unit of an air conditioner (not shown).

As an example, the heat exchanging unit 40 includes a compressor 410 and an evaporator 420, the compressor 410 is disposed in the cabinet 10, and the evaporator 420 is communicated with the compressor 410 and disposed between the first air return 103 and the second air return 105 for converting hot air into cold air.

The outdoor unit of the air conditioner may include a condenser, and the compressor 410, the evaporator 420, the condenser and the throttling assembly form a refrigeration cycle line such that the evaporator 420 converts hot air into cold air.

The evaporator 420 includes a first evaporation plate 421 and a second evaporation plate 422, and the first evaporation plate 421 and the second evaporation plate 422 each extend along the spacing direction of the first side plate 151 and the second side plate 152.

The first evaporation plate 421 and the second evaporation plate 422 are in an inverted V shape. The angle of the V may be toward the top panel 155 of the cabinet 10 and the opening of the V may be toward the bottom panel 156 of the cabinet 10.

The first evaporating plate 421 and the second evaporating plate 422 are inverted V-shaped, and the first evaporating plate 421 and the second evaporating plate 422 both extend along the interval direction of the first side plate 151 and the second side plate 152, so that the evaporator 420 is arranged along the arrangement direction of the communication equipment 200 to form two-sided back-heating air and two-sided back-cooling air, and the effect of maximizing the heat exchange area is achieved.

It can be understood that heat exchange unit 40 can be compressor type, fluorine pump type, compressor + fluorine pump mixed type, and the compressor type can cooperate the air-cooled radiator commonly used, and the refrigerated water of the usable central air conditioning of fluorine pump type to send low temperature fluorine liquid to refrigerate after the heat transfer of board-like heat transfer water fluorine, and compressor + fluorine pump mixed type can make full use of nature cold source.

Note that, as shown in fig. 6, the first air return opening 103 is located above an orthographic projection of the evaporator 420 to the first side plate 151. Similarly, the second air return opening 105 is located above the orthographic projection of the evaporator 420 to the second side plate 152. In this way, the hot air returned from the first and second air returns 103 and 105 can pass through the evaporator 420 within the cabinet 10, thereby achieving heat exchange.

Of course, in other embodiments, the orthographic projection of the evaporator 420 onto the first side plate 151 may divide the first air return 103 into two portions, wherein a majority of the first air return 103 is located above the evaporator 420 and a minority of the first air return 103 is located below the evaporator 420. The second air return opening 105 and the evaporator 420 are similar to the first air return opening 103 in position, and are not described in detail herein.

Referring back to fig. 4, the air channel 101 includes a hot air channel and a cold air channel, the first air return opening 103 and the second air return opening 105 are communicated with the hot air channel, and the first air outlet 102 and the second air outlet 104 are communicated with the cold air channel.

The air conditioner 100 further includes a partition 60 that is detachably connected to the cabinet 10 to block or communicate the hot air path and the cold air path.

When a plurality of air conditioners 100 are arranged side by side, if one of the air conditioners 100 fails, a partition 60 may be inserted into the cabinet 10 to block the hot air passage and the cold air passage, thereby preventing the occurrence of wind cross inside the failed air conditioner 100.

It should be noted that, if each air conditioner 100 is operating normally, the airflow direction is: under the action of the fan 50, the cold air flows out from the air outlet, and after passing through the communication device 200, the temperature rises to become hot air, and the hot air enters the cabinet 10 from the air return opening. When the air conditioner 100 fails (for example, the fan 50 does not operate), the cold air loses the power flowing to the communication device 200, and on the contrary, under the reaction of the wind pressure generated when the communication device 200 operates, the hot air generated by the communication device 200 enters the cabinet 10 from the wind outlet, so that the wind cross occurs.

The air conditioning system of the embodiment of the present invention further includes a control unit, which can realize group control of the plurality of air conditioning devices 100, so as to ensure that the rotation speed, the wind pressure and the working state of the compressor of the fan 50 of each air conditioning device 100 are substantially the same. Also, when the air conditioner device 100 malfunctions, a fault condition may be protected and alarmed in real time. In addition, the control unit can also realize the remote monitoring reporting function.

As shown in fig. 7 and 8, fig. 7 is a schematic view of the air conditioner 100 for communication equipment according to the second embodiment of the present invention before the first and second cabinets 120 and 130 are unfolded. Fig. 8 is a schematic diagram showing the first sliding cabinet 120 and the second sliding cabinet 130 of the air conditioner 100 for communication equipment according to the second embodiment of the present invention after being unfolded.
