Description

Technical Field

[0001] The present invention relates to the field of air conditioning and refrigeration technology, and more specifically, to an air conditioning device and air conditioning system for communication equipment. Background Technology

[0002] Communication equipment in a communication equipment room consumes a large amount of electricity, and the heat generated by this equipment needs to be dissipated through the room's air conditioning. Currently, air conditioning accounts for nearly half of the total electricity consumption in communication equipment rooms, making energy-efficient air conditioning crucial for the construction of green equipment rooms.

[0003] With the increasingly widespread commercial use of high-power communication equipment, numerous problems have arisen in its application in data centers. On one hand, the increased power consumption stems from inadequate thermal design of communication equipment. For example, Optical Transport Network (OTN) equipment, a primary transmission device in the internet communication era, consumes nearly 20kW at its maximum capacity in 100-400Gbit / s OTN cabinets. Furthermore, these cabinets employ a back-to-back double-sided architecture, requiring cold air intake on both sides and hot air exhaust from both top and bottom. Ordinary air conditioning solutions have encountered significant limitations in handling high-power OTN equipment. On the other hand, older data centers release heat from communication equipment into the room, which is then transferred outdoors by the data center air conditioning system. Outdated cooling architectures fail to isolate hot and cold airflows and do not consider the impact of airflow organization on energy efficiency, resulting in significant energy losses for the air conditioning units and low overall energy efficiency. Summary of the Invention

[0004] This invention provides an air conditioning device and system for communication equipment, which can reasonably and efficiently solve the heat dissipation problem of communication equipment based on its structural characteristics.

[0005] An air conditioning device for communication equipment according to an embodiment of the present invention includes a cabinet, an air outlet baffle, a return air baffle, a heat exchange unit, and a fan.

[0074] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0075] like Figure 1 and Figure 2 As shown, Figure 1 The diagram shown is a front view of an air conditioning system according to an embodiment of the present invention. Figure 2 The diagram shown is a top view of an air conditioning system according to an embodiment of the present invention. The air conditioning system of this embodiment includes multiple air conditioning units 100, multiple communication devices 200, and multiple circulation components 300. The multiple air conditioning units 100 are arranged side-by-side, and each communication device 200 is disposed between two adjacent air conditioning units 100. Each circulation component 300 is disposed between two adjacent air conditioning units 100. The air conditioning units 100, through the circulation components 300, achieve cold air delivery and hot air recovery to cool the communication devices 200.

[0076] By arranging multiple circulation components 300, the air conditioning system can form a cabinet-level cooling unit. Multiple air conditioning units 100 arranged side-by-side can increase cooling capacity, simultaneously cooling multiple communication devices 200.

[0077] The circulation component 300 is sealed to the air conditioning unit 100 to prevent hot and cold air from spreading outside the air conditioning unit 100 and the circulation component 300, thus avoiding any impact on the computer room environment of the communication equipment 200.

[0078] It should be noted that, in order to simplify the view, Figure 1 and Figure 2 Only two air conditioning units 100, one communication device 200, and one circulation component 300 are shown.

[0079] Of course, in other embodiments, the air conditioning system may also include only an air conditioning unit 100, a communication device 200 and a circulation component 300, with the communication device 200 and the circulation component 300 disposed on one side of the air conditioning unit 100.

[0080] In another embodiment, the air conditioning system may also include only one air conditioning unit 100, two communication devices 200 and two circulation components 300, with the two communication devices 200 respectively disposed on both sides of the air conditioning unit 100 and the two circulation components 300 respectively disposed on both sides of the air conditioning unit 100.

[0081] like Figure 3 and Figure 4 As shown, Figure 3 The diagram shown is a schematic diagram of an air conditioning device 100 for a communication device according to a first embodiment of the present invention. Figure 4 What is shown is Figure 3 An exploded view diagram. It should be noted that, in order to show the internal structure, Figures 3 to 8 The outer wall of the cabinet is made transparent.

[0082] The air conditioning device 100 for communication equipment of the present invention includes a cabinet 10, multiple air outlet baffles 20, multiple return air baffles 30, a heat exchange unit 40, and a fan 50.

[0083] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0084] As an example, the cabinet 10 can be generally a cuboid 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 arranged opposite each other along a second direction D2. The first side plate 151 is connected to the top plate 155 and the bottom plate 156, and 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 arranged opposite each other along a 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, and 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 arranged opposite each other along a first direction D1. The first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0085] Of course, in other embodiments, the cabinet 10 can also be in other shapes, which will not be listed here.

[0086] A gas passage 101 is formed between the first side plate 151 and the second side plate 152. The first side plate 151 has at least one first air outlet 102 and at least one first return air outlet 103 corresponding to the first air outlet 102. The second side plate 152 has at least one second air outlet 104 and at least one second return air outlet 105 corresponding to the second air outlet 104. The first air outlet 102, the first return air outlet 103, the second air outlet 104 and the second return air outlet 105 are all connected to the gas passage 101.

[0087] It is understandable that the number of air outlets (including the first air outlet 102 and the second air outlet 104) is the same as the number of return air outlets (including the first return air outlet 103 and the second return air outlet 105).

[0088] As an example, the first air outlet 102 is located at the bottom of the first side panel 151, and the first return air outlet 103 is located at the top of the first side panel 151. The second air outlet 104 is located at the bottom of the second side panel 152, and the second return air outlet 105 is located at the top of the second side panel 152. By placing the air outlet at the bottom of the cabinet 10 and the return air outlet at the top of the cabinet 10, the air outlet and return air outlet of the cabinet 10 can be adapted to the characteristics of hot air being lighter and cold air being heavier, so that the lighter hot air enters the cabinet 10 from the higher return air outlet, while the heavier cold air flows out of the cabinet 10 from the lower air outlet.

[0089] As an example, there are two of each of the following: first air outlet 102, first return air outlet 103, second air outlet 104, and second return air outlet 105. Along the first direction D1, the two first air outlets 102, two second air outlets 104, two first return air outlets 103, and two second return air outlets 105 are spaced apart, and the area between the two first air outlets 102 of the first side plate 151 forms a first placement area 141, and the area between the two second air outlets 104 of the second side plate 152 forms a second placement area 142.

[0090] The first placement area 141 of the first side panel 151 is used to place the communication device 200, and the communication device 200 rests against the first placement area 141. When the communication device 200 is placed in the first placement area 141, the cold air blown out by the two first air outlets 102 of the first side panel 151 can cool down the two opposite sides of the communication device 200, so as to solve the heat dissipation problem of the high-power communication device 200.

[0091] Similarly, the second placement area 142 of the second side panel 152 is used to place another communication device 200, which rests against the second placement area 142. When the communication device 200 is placed in the second placement area 142, the cold air blown out by the two second air outlets 104 of the second side panel 152 can cool the two opposite sides of the communication device 200, thereby solving the heat dissipation problem of the high-power communication device 200.

[0092] Along the second direction D2, the first air outlet 102 corresponds to the first return air outlet 103, and the second air outlet 104 corresponds to the second return air outlet 105.

[0093] It is understandable that the air outlets (including the first air outlet 102 and the second air outlet 104) can be rectangular, rhomboid, circular, or other shapes to meet the air supply requirements of different communication devices 200. The return air outlets (including the first return air outlet 103 and the second return air outlet 105) can be rectangular, rhomboid, circular, or other shapes to meet the air supply requirements of different communication devices 200.

[0094] Furthermore, the shape of the air outlet and the return air outlet can be the same or different. The shapes of the first air outlet 102 and the second air outlet 104 can be the same or different. The shapes of the first return air outlet 103 and the second return air outlet 105 can be the same or different.

[0095] Of course, in other embodiments, the corresponding first air outlet 102 and first air return outlet 103 may also be arranged along the diagonal of the first side plate 151.

[0096] It is understandable that the number of first air outlets 102 on the first side panel 151 can be one, three, or more. The number of second air outlets 104 on the second side panel 152 can also be one, three, or more.

[0097] Multiple air outlet baffles 20 correspond to the number of first air outlets 102 and second air outlets 104, and are used to open and close the first air outlets 102 and second air outlets 104. Multiple return air baffles 30 correspond to the number of first return air inlets 103 and second return air inlets 105, and are used to open and close the first return air inlets 103 and second return air inlets 105.

[0098] In other words, the number of air outlet baffles 20 is equal to the sum of the number of the first air outlet 102 and the second air outlet 104. Similarly, the number of return air baffles 30 is equal to the sum of the number of the first return air outlet 103 and the second return air outlet 105.

[0099] As an example, when there are two first air outlets 102, two second air outlets 104, two first return air outlets 103, and two second return air outlets 105, there are four air outlet baffles 20 and four return air baffles 30.

[0100] Of course, in other embodiments, the number of air outlet baffles 20 may be less than the sum of the number of the first air outlets 102 and the second air outlets 104. For example, when the sum of the number of the first air outlets 102 and the second air outlets 104 is four, the number of air 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 the first return air inlets 103 and the second return air inlets 105. For example, when the sum of the number of the first return air inlets 103 and the second return air inlets 105 is four, the number of return air baffles 30 may be one, two, or three.

[0101] By selectively opening and closing different air outlets with the air outlet baffle 20 and selectively opening and closing different return air outlets with the return air baffle 30, the air conditioning device 100 of this embodiment can be adapted to the single-sided and / or double-sided cooling of the communication equipment 200, and can also be adapted to the situation of mixed single-sided and double-sided cooling of the communication equipment 200. The pPUE (Partial Power Usage Effectiveness) can reach 1.15 to 1.2, and the energy-saving effect is obvious.

[0102] Specifically, when the communication device 200 is installed only in the first placement area 141 of the first side panel 151 in the air conditioning device 100 of this embodiment, and both sides of the communication device 200 need to be cooled, only two first air outlets 102 and two first return air outlets 103 need to be opened, while the air outlets and return air outlets of the second side panel 152 are closed. When only one side of the communication device 200 needs to be cooled, only one corresponding first air outlet 102 and one first return air outlet 103 of the first side panel 151 need to be opened, while the remaining air outlets and return air outlets are closed.

[0103] When communication devices 200 are provided in both the first placement area 141 and the second placement area 142 of the air conditioning device 100 in this embodiment of the invention, the two first air outlets 102, the two second air outlets 104, the two first return air outlets 103, and the two second return air outlets 105 of the air conditioning device 100 can be opened to cool both sides of each communication device 200. Alternatively, only one corresponding first air outlet 102 and one corresponding first return air outlet 103 in the first side plate 151, and one corresponding second air outlet 104 and one corresponding second return air outlet 104 in the second side plate 152 can be opened, while the remaining air outlets and return air outlets are closed to cool only one side of each communication device 200.

[0104] It is understandable that the air outlet baffle 20 can be used in various ways to open and close the first air outlet 102 and the second air outlet 104. For example, the air outlet baffle 20 can be fastened to the air outlet. When it is necessary to close the air outlet, the air outlet baffle 20 is fastened to the air outlet. When it is necessary to open the air outlet, the air outlet baffle 20 is removed from the air outlet. The air outlet baffle 20 can be fastened to the air outlet by bolts, but is not limited to this method.

[0105] Alternatively, the air outlet baffle 20 can be slidably connected relative to the first side plate 151 and the second side plate 152. When it is necessary to close the air outlet, the air outlet baffle 20 slides relative to the first side plate 151 and the second side plate 152 to cover the air outlet. When it is necessary to open the air outlet, the air outlet baffle 20 slides open from the air outlet to expose the air outlet.

[0106] The way the return air damper 30 opens and closes the first return air inlet 103 and the second return air inlet 105 can be the same as that of the outlet damper 20, and will not be described again here.

[0107] like Figure 5 and Figure 6 As shown, Figure 5 The image shown is a front view of an air conditioning unit 100 for a communication device according to a first embodiment of the present invention. Figure 6 The diagram shows a side view of an air conditioning unit 100 for a communication device according to a first embodiment of the present invention. A heat exchange unit 40 is disposed inside the cabinet 10 and is used to convert hot air into cold air. A fan 50 is disposed inside the cabinet 10 and is used to drive cold air out through a first air outlet 102 and / or a second air outlet 104.

[0108] The heat exchange unit 40 can be regarded as an indoor unit of an air conditioner. The heat exchange unit 40 works in conjunction with the outdoor unit of the air conditioner (not shown in the figure) to convert hot air into cold air.

[0109] As an example, the heat exchange unit 40 includes a compressor 410 and an evaporator 420. The compressor 410 is located inside the cabinet 10, and the evaporator 420 is connected to the compressor 410 and located between the first return air inlet 103 and the second return air inlet 105, for converting hot air into cold air.

[0110] An outdoor unit of an air conditioner may include a condenser, a compressor 410, an evaporator 420, and a throttling component forming a refrigeration cycle pipeline so that the evaporator 420 converts hot air into cold air.

[0111] The evaporator 420 includes a first evaporation plate 421 and a second evaporation plate 422, both of which extend along the interval direction between the first side plate 151 and the second side plate 152.

[0112] The first evaporator plate 421 and the second evaporator plate 422 are inverted V-shaped. The sharp corner of the V-shape can face the top plate 155 of the cabinet 10, and the opening of the V-shape can face the bottom plate 156 of the cabinet 10.

[0113] By arranging the first evaporator plate 421 and the second evaporator plate 422 in an inverted V shape, and with both the first evaporator plate 421 and the second evaporator plate 422 extending along the interval direction of the first side plate 151 and the second side plate 152, the evaporator 420 is arranged along the arrangement direction of the communication equipment 200, so as to form two sides of hot air return and two sides of cold air return, thereby maximizing the heat exchange area.

[0114] It is understandable that the heat exchange unit 40 can be a compressor type, a refrigerant pump type, or a compressor + refrigerant pump hybrid type. The compressor type can be used with commonly used air-cooled radiators, the refrigerant pump type can utilize the chilled water of the central air conditioning system, and send low-temperature refrigerant liquid for cooling after heat exchange with the refrigerant through a plate heat exchanger, and the compressor + refrigerant pump hybrid type can make full use of natural cold sources.

[0115] It should be noted that, as Figure 6 As shown, the first return air vent 103 is located above the orthographic projection of the evaporator 420 onto the first side panel 151. Similarly, the second return air vent 105 is located above the orthographic projection of the evaporator 420 onto the second side panel 152. In this way, the hot air returning from the first return air vent 103 and the second return air vent 105 can pass through the evaporator 420 within the cabinet 10, thereby achieving heat exchange.

[0116] Of course, in other embodiments, the orthographic projection of the evaporator 420 onto the first side plate 151 can divide the first return air vent 103 into two parts, with most of the first return air vent 103 located above the evaporator 420 and a small portion located below the evaporator 420. The positional relationship between the second return air vent 105 and the evaporator 420 is similar to that of the first return air vent 103, and will not be described again here.

[0117] Please return to the reference. Figure 4 The gas passage 101 includes a hot air passage and a cold air passage. The first return air inlet 103 and the second return air inlet 105 are connected to the hot air passage, and the first air outlet 102 and the second air outlet 104 are connected to the cold air passage.

[0118] The air conditioning unit 100 also includes a partition 60, which is pluggably connected to the cabinet 10 and is used to block or open the hot air passage and the cold air passage.

[0119] When multiple air conditioning units 100 are arranged side by side, if one of the air conditioning units 100 malfunctions, a partition 60 can be inserted into the cabinet 10 to block the hot air passage and the cold air passage, thus preventing air leakage inside the malfunctioning air conditioning unit 100.

[0120] It should be noted that if each air conditioning unit 100 operates normally, the airflow direction is as follows: under the action of the fan 50, cold air flows out from the air outlet, and after passing through the communication equipment 200, its temperature rises and it becomes hot air. The hot air then enters the cabinet 10 from the return air inlet. When the air conditioning unit 100 malfunctions (for example, the fan 50 does not work), the cold air loses its power to flow to the communication equipment 200. Instead, due to the reaction force of the air pressure generated when the communication equipment 200 is working, the hot air generated by the communication equipment 200 will enter the cabinet 10 from the air outlet, resulting in cross-ventilation.

[0121] The air conditioning system in this embodiment of the invention also includes a control unit, which can realize group control of multiple air conditioning units 100 to ensure that the fan speed 50, air pressure, and compressor operating status of each air conditioning unit 100 are basically the same. Furthermore, when an air conditioning unit 100 malfunctions, it can provide real-time protection and alarm notification of the fault status. In addition, the control unit can also realize remote monitoring and reporting functions.

[0122] like Figure 7 and Figure 8 As shown, Figure 7 The diagram shown is a schematic diagram of the first sliding cabinet 120 and the second sliding cabinet 130 of the air conditioning device 100 for communication equipment according to the second embodiment of the present invention before they are unfolded. Figure 8 The diagram shown is a schematic representation of the first sliding cabinet 120 and the second sliding cabinet 130 of the air conditioning unit 100 for communication equipment according to the second embodiment of the present invention, after being unfolded. The similarities between the second embodiment and the first embodiment will not be repeated here, but the difference lies in that the size of the air conditioning unit 100 is adjustable to accommodate communication equipment 200 of different thicknesses.

[0123] Specifically, the cabinet 10 may include a main body 110, a first sliding cabinet 120 and a second sliding cabinet 130. The first sliding cabinet 120 and the second sliding cabinet 130 are slidably connected to two opposite sides of the main body 110. The first sliding cabinet 120, the second sliding cabinet 130 and the main body 110 together form a gas channel 101.

[0124] A portion of the first air outlet 102, a portion of the first return air outlet 103, a portion of the second air outlet 104, and a portion of the second return air outlet 105 are located on the first sliding cabinet 120, while another portion of the first air outlet 102, another portion of the first return air outlet 103, another portion of the second air outlet 104, and another portion of the second return air outlet 105 are located on the second sliding cabinet 130.

[0125] As an example, the number of first air outlets 102, second air outlets 104, first return air outlets 103, and second return air outlets 105 are all two. The first sliding cabinet 120 has one first air outlet 102, one first return air outlet 103, one second air outlet 104, and one second return air outlet 105. The second sliding cabinet 130 has one first air outlet 102, one first return air outlet 103, one second air outlet 104, and one second return air outlet 105.

[0126] Combination Figure 7 and Figure 8As can be seen, by sliding the first sliding cabinet 120 and the second sliding cabinet 130 relative to the main body 110, the distance between the two first air outlets 102, the distance between the two first return air outlets 103, the distance between the two second air outlets 104, and the distance between the two second return air outlets 105 can be adjusted. In other words, the dimensions of the first direction D1 of the first placement area 141 and the second placement area 142 are adjustable to allow the air conditioning unit 100 to adapt to communication equipment 200 of different thicknesses.

[0127] As an example, the dimensions of the air conditioning unit 100 can be: width × thickness × height = 750mm × (1000mm-1400mm) × 2200mm, that is, the thickness of the air conditioning unit 100 can be flexibly adjusted between 1000mm and 1400mm.

[0128] Please continue reading. Figure 7 and Figure 8 The main body 110 includes a first fixed cabinet panel 111 and a second fixed cabinet panel 112 arranged opposite to each other. The first sliding cabinet 120 includes a first cabinet panel 121 and a second cabinet panel 122 arranged opposite to each other. The second sliding cabinet 130 includes a third cabinet panel 131 and a fourth cabinet panel 132 arranged opposite to each other. Parts of the first fixed cabinet panels 111, 121, and 131 constitute a first side panel 151, and parts of the second fixed cabinet panels 112, 122, and 132 constitute a second side panel 152. That is, the areas of the first side panel 151 and the second side panel 152 in this embodiment are variable.

[0129] Part of the first air outlet 102 and part of the first return air outlet 103 are located on the first cabinet panel 121, another part of the first air outlet 102 and another part of the first return air outlet 103 are located on the third cabinet panel 131, part of the second air outlet 104 and part of the second return air outlet 105 are located on the second cabinet panel 122, and another part of the second air outlet 104 and another part of the second return air outlet 105 are located on the fourth cabinet panel 132.
