Technical Field

[0001] This application relates to the field of refrigeration technology, and in particular to a cooling system for a duct component and communication equipment. Background Technology

[0002] Communication equipment in a communication room consumes a lot of electrical energy and generates a lot of heat when it is working. Therefore, cooling the communication equipment in the room is extremely important and affects the performance stability and service life of the communication equipment.

[0003] In related technologies, to improve cooling efficiency, a precision cooling solution has been proposed, which involves installing air conditioning units alongside server racks and constructing a fully enclosed hot and cold aisle with related air duct components to achieve rack-level precision cooling. However, some data centers, due to space constraints, cannot achieve parallel installation of air conditioning units and server racks, creating obstacles to the implementation of rack-level precision cooling solutions. Summary of the Invention

[0004] Based on this, a cooling system for air duct components and communication equipment is provided to solve the problem that rack-level precision cooling solutions cannot be implemented due to space limitations in the computer room.

[0005] An embodiment of the first aspect of this application provides an air duct component, the air duct component including a component body, the component body having a first air duct and a second air duct disposed inside, and the component body having a first air duct opening, a second air duct opening, a third air duct opening and a fourth air duct opening; wherein, the first air duct opening is disposed at the top or bottom of the component body and communicates with the first air duct, the second air duct opening is disposed on one side of the component body and communicates with the first air duct, the third air duct opening is disposed at the top or bottom of the component body and communicates with the second air duct, and the fourth air duct opening is disposed on one side of the component body and communicates with the second air duct; the opening directions of the first air duct opening and the third air duct opening are arranged in a vertical direction, and the opening directions of the second air duct opening and the fourth air duct opening are arranged in a horizontal direction.

[0006] In this embodiment of the application, one of the first and second air ducts of the air duct component can be used as a hot air duct, and the other can be used as a cold air duct. Taking the first air duct as a hot air duct and the second air duct as a cold air duct as an example, an air duct component can be installed near the air conditioning unit and another near the communication equipment cabinet. The two air duct components can be connected by an air supply duct assembly. The cold air provided by the air conditioning unit enters the second air duct of the air duct component through the fourth air duct opening, and then enters the air supply duct assembly through the third air duct opening. The cold air then reaches the other air duct component installed near the cabinet through the air supply duct assembly, enters the second air duct through the third air duct opening of that air duct component, and finally enters the cold air channel of the cabinet through the fourth air duct opening. Hot air in the return air duct of the cabinet can enter the first air duct through the second air duct opening of the air duct component, and then enter the air supply duct assembly through the first air duct opening. The hot air reaches the air duct component near the air conditioning unit through the air supply duct assembly, and enters the first air duct through the first air duct opening of the air duct component. Finally, it enters the return air vent of the air conditioning unit through the second air duct opening.

[0043] Communication equipment in a communication room consumes a lot of electrical energy and generates a lot of heat when it is working. Therefore, cooling the communication equipment in the room is extremely important and affects the performance stability and service life of the communication equipment.

[0044] In related technologies, to improve cooling efficiency, a precision cooling solution has been proposed, which involves installing air conditioning units alongside server racks and constructing a fully enclosed hot and cold aisle with related air duct components to achieve rack-level precision cooling. However, some data centers, due to space constraints, cannot achieve parallel installation of air conditioning units and server racks, creating obstacles to the implementation of rack-level precision cooling solutions.

[0045] Based on the above problems, the embodiments of the first aspect of this application propose an air duct component, which aims to solve the problem that rack-level precision cooling solutions cannot be implemented due to space limitations in the computer room.

[0046] like Figures 1 to 4 As shown, the air duct component 100 in the first aspect embodiment of this application includes a component body. A first air duct 101 and a second air duct 102 are disposed inside the component body. A first air duct opening 103, a second air duct opening 104, a third air duct opening 105, and a fourth air duct opening 106 are disposed on the component body. The first air duct opening 103 is located at the top or bottom of the component body and communicates with the first air duct 101. The second air duct opening 104 is located on one side of the component body and communicates with the first air duct 101. The third air duct opening 105 is located at the top or bottom of the component body and communicates with the second air duct 102. The fourth air duct opening 106 is located on one side of the component body and communicates with the second air duct 102. The opening directions of the first air duct opening 103 and the third air duct opening 105 are vertical, while the opening directions of the second air duct opening 104 and the fourth air duct opening 106 are horizontal.

[0047] In this embodiment of the application, one of the first air duct 101 and the second air duct 102 of the air duct component 100 can be used as a hot air duct, and the other of the first air duct 101 and the second air duct 102 can be used as a cold air duct. Taking the first air duct 101 as a hot air duct and the second air duct 102 as a cold air duct as an example, one air duct component 100 can be installed near the air conditioning unit 200 and another near the cabinet 300 of the communication equipment. The two air duct components 100 can be connected by an air supply duct assembly 400. The cold air provided by the air conditioning unit 200 can enter the second air duct 102 of the air duct component 100 through the fourth air duct port 106, and enter the air supply duct assembly 400 through the third air duct port 105. The cold air then reaches another air duct component 100 located near the server rack 300 through the air supply duct assembly 400, and enters the second air duct 102 through the third air duct port 105 of that air duct component 100, and finally enters the cold air aisle of the server rack 300 through the fourth air duct port 106. The hot air in the return air aisle of the server rack 300 can enter the first air duct 101 through the second air duct port 104 of the air duct component 100, and enter the air supply duct assembly 400 through the first air duct port 103. The hot air then reaches the air duct component 100 located near the air conditioning unit 200 through the air supply duct assembly 400, and enters the first air duct 101 through the first air duct port 103 of the air duct component 100, and finally enters the return air vent of the air conditioning unit 200 through the second air duct port 104.

[0048] As can be seen from the above process, by using two air duct components 100 in conjunction with the corresponding air supply duct assembly 400, a closed hot and cold air channel can be constructed between the air conditioning unit 200 and the cabinet 300, so that cold air and hot air can circulate efficiently between the air conditioning unit 200 and the cabinet 300, enabling the implementation of a cabinet 300-level cooling solution for communication equipment.

[0049] Understandably, the first air duct opening 103 and the third air duct opening 105 can be located at either the top or bottom of the main body of the component. Since the first air duct opening 103 and the third air duct opening 105 need to connect to the air supply duct assembly 400, when the first air duct opening 103 and the third air duct opening 105 are located at the bottom of the main body of the component, the air supply duct assembly 400 needs to be routed from below the floor of the equipment room. In this case, the equipment room needs to use a raised floor to provide space for the air supply duct assembly 400 to be routed.

[0050] In some embodiments, the main body of the component includes a fixed frame 110, a first air guide 120, and a second air guide 130. The fixed frame 110 defines an installation space, the first air guide 120 is disposed in the installation space, and the first air guide 120 and the fixed frame 110 together define a first air duct 101. The second air guide 130 is disposed in the installation space, and the second air guide 130 and the fixed frame 110 together define a second air duct 102. Thus, by providing the first air guide 120 and the second air guide 130 in the installation space of the fixed frame 110, the first air duct 101 and the second air duct 102 are constructed inside the main body of the component.

[0051] In some embodiments, the second air guide 130 includes a first segment 131 and a second segment 132. The first segment 131 is provided with a vertically extending air cavity 1311, and the lower part of the first segment 131 is provided with an opening communicating with the air cavity 1311. The second segment 132 is disposed at the opening and defines a fourth air duct opening 106. In this embodiment, the second air guide 130 includes a first segment 131 and a second segment 132, wherein the upper end of the first segment 131 is directly connected to the third air duct opening 105, and the first segment 131 is used to move cold air vertically. The second segment 132 is connected to the first segment 131 and defines a fourth air duct opening 106 arranged horizontally. Through the cooperation of the first segment 131 and the second segment 132, the direction of movement of cold air in the second air duct 102 can be changed. For example, cold air from the air conditioning unit 200 can enter the air cavity 1311 of the first section 131 through the third air duct 105, and move downward along the air cavity 1311. Then, at the connection point between the first section 131 and the second section 132, it turns to move horizontally and is discharged through the fourth air duct 106 defined by the second section 132.

[0052] In some embodiments, the first air guide 120 is disposed above the second section 132. Since the second section 132 of the second air guide 130 is connected to one side of the lower part of the first section 131, further disposing the second air guide 130 above the second section 132 helps to reduce the gap between the first air guide 120 and the second air guide 130, thereby improving space utilization and helping to avoid the duct component 100 from becoming too large.

[0053] In some embodiments, the first air guide 120 is provided with a first arc-shaped air guide portion 121. The first section 131 is provided with a second arc-shaped air guide portion 1312, and the second section 132 is provided with a third arc-shaped air guide portion 1321. As can be seen from the fact that the opening directions of the first air duct opening 103 and the third air duct opening 105 are arranged vertically, and the opening directions of the second air duct opening 104 and the fourth air duct opening 106 are arranged horizontally, both the first air duct 101 and the second air duct 102 can change the direction of air movement within them. For example, the first air duct 101 can change the direction of movement of hot air entering it from horizontal to vertical, or vice versa. Similarly, the second air duct 102 can change the direction of movement of cold air entering it. Based on this, the first air guide 120 is provided with a first arc-shaped air guide portion 121, which reduces energy loss when the direction of movement of hot air changes in the first air duct 101. Similarly, the first section 131 is provided with a second arc-shaped air guide 1312, and the second section 132 is provided with a third arc-shaped air guide 1321. This arrangement can reduce the energy loss when the direction of movement of cold air changes in the second air duct 102.

[0054] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixed frame 110 includes a first frame body 111 and a second frame body 112. A slide rail 113 is provided on the first frame body 111, and a groove 1111 that mates with the slide rail 113 is provided on the second frame body 112. Each of the first frame body 111 and the second frame body 112 defines a placement space. A first air guide 120 and a second air guide 130 are provided within each placement space.

[0055] In this embodiment, the first frame 111 and the second frame 112 are each provided with a placement space. Each placement space is provided with a first air guide 120 and a second air guide 130, so that a first air duct 101 and a second air duct 102 are formed in the first frame 111, and a first air duct 101 and a second air duct 102 are also formed in the second frame 112. In this way, the air duct component 100 can be adapted to an air conditioning device 200 with two cold air inlets and two return air inlets in the related art. That is, one cold air inlet and one return air inlet of the air conditioning device 200 are respectively connected to the second air duct 102 and the first air duct 101 in the first frame 111, and the other cold air inlet and the other return air inlet of the air conditioning device 200 are respectively connected to the second air duct 102 and the first air duct 101 in the second frame 112. It is understood that when the air duct component 100 in this embodiment is connected to the cabinet 300, it can be connected to the two cold air ducts and two return air ducts in the cabinet 300. One of the cold air ducts and one of the return air ducts in the cabinet 300 are located on the front of the cabinet 300, and the other cold air duct and the other return air duct in the cabinet 300 are located on the back of the cabinet 300.

[0056] It is understood that, in accordance with the fact that both the first frame body 111 and the second frame body 112 are provided with a first air duct 101 and a second air duct 102, both the first frame body 111 and the second frame body 112 are also provided with a first air duct opening 103, a second air duct opening 104, a third air duct opening 105 and a fourth air duct opening 106.

[0057] In addition, the first frame 111 is provided with a slide rail 113, and the second frame 112 is provided with a slide groove 1111 that cooperates with the slide rail 113. That is, by sliding the second frame 112 on the slide rail 113, the distance between the second frame 112 and the first frame 111 can be adjusted more flexibly so that the air duct component 100 can be adapted to air conditioning units 200 of different specifications or cabinets 300 of different specifications.

[0058] Furthermore, such as Figure 2 As shown, both the first frame body 111 and the second frame body 112 may further include a support structure 115 and a panel 116 fixed on the support structure. The support structure 115 is mainly used to provide structural strength and rigidity, and the panel 116 is mainly used to form a closed structure so as to form a first air duct 101 and a second air duct 102 within the fixed frame 110.

[0059] In some embodiments, there are multiple slide rails 113, with slide rails 113 provided at both the top and bottom of the first frame body 111. Slide grooves 1111 are provided at both the top and bottom of the second frame body 112. This arrangement helps improve the movement stability of the second frame body 112 relative to the first frame body 111, preventing the second frame body 112 from tipping over during movement.

[0060] In some embodiments, the air duct component 100 may further include a heat insulation layer (not shown in the figure), which is disposed between the first air guide 120 and the fixed frame 110, and between the second air guide 130 and the fixed frame 110. This arrangement helps to reduce the loss of cold energy, thereby improving cooling efficiency.

[0061] In some embodiments, the second air duct 104 and the fourth air duct 106 are located on the same side of the main body of the component, which helps to avoid setting up too many pipes and avoids the pipes being set up in a tortuous and complicated manner.

[0062] In some embodiments, an axial flow fan is provided on at least one of the first air duct opening 103, the second air duct opening 104, the third air duct opening 105, and the fourth air duct opening 106. When the distance between the air conditioning unit 200 and the cabinet 300 is far, an axial flow fan can be installed on one or more of the first air duct opening 103, the second air duct opening 104, the third air duct opening 105, and the fourth air duct opening 106 to meet the needs of long-distance delivery of cold air and / or return air.

[0063] An embodiment of the second aspect of this application provides a cooling system for communication equipment, such as... Figure 4 As shown, the cooling system for communication equipment includes an air conditioning unit 200, a first air duct component 100a, a second air duct component 100b, and an air supply duct assembly 400. The first air duct component 100a is connected to the air conditioning unit 200, and the second air duct component 100b is used to connect to the cabinet 300. The first air duct component 100a and the second air duct component 100b are connected through the air supply duct assembly 400. The first air duct component 100a and the second air duct component 100b are both air duct components 100 in any of the above embodiments.

[0064] The cooling system for communication equipment in this embodiment of the application includes an air conditioning unit 200 connected to a first air duct component 100a, and a second air duct component 100b connected to the cabinet 300 of the communication equipment. The first air duct component 100a and the second air duct component 100b are connected by an air supply duct assembly 400. Through the first air duct component 100a, the second air duct component 100b, and the air supply duct assembly 400, a closed hot and cold air channel can be constructed between the air conditioning unit 200 and the cabinet 300, allowing for efficient circulation of cold and hot air between them. This enables the implementation of a cabinet-level cooling solution for the communication equipment.

[0065] Furthermore, the air conditioning unit 200 has a cold air outlet and a return air outlet. The cabinet 300 has a cold air duct and a return air duct. The air supply duct assembly 400 includes a first air supply duct 410 and a second air supply duct 420. The fourth air duct opening 106 of the first air duct component 100a is connected to the cold air outlet, the third air duct opening 105 of the first air duct component 100a is connected to one end of the first air supply duct 410, the other end of the first air supply duct 410 is connected to the third air duct opening 105 of the second air duct component 100b, and the fourth air duct opening 106 of the second air duct component 100b is used to connect to the cold air duct of the cabinet 300. The second air duct opening 104 of the second air duct component 100b is used to connect to the return air duct of the cabinet 300. The first air duct opening 103 of the second air duct component 100b is connected to one end of the second air supply pipe 420. The other end of the second air supply pipe 420 is connected to the first air duct opening 103 of the first air duct component 100a. The second air duct opening 104 of the first air duct component 100a is connected to the return air vent.

[0066] This configuration creates a closed hot and cold air passage between the air conditioning unit 200 and the cabinet 300, allowing cold and hot air (return air) to circulate efficiently between the air conditioning unit 200 and the cabinet 300.

[0067] It should be noted that the number of the first air supply duct 410 and the second air supply duct 420 between the air conditioning unit 200 and the cabinet 300 can be adjusted according to usage requirements. For example, as Figure 5 As shown, the cabinet 300 can open only the cold air passage and return air passage located on the front. In this case, it is only necessary to connect one first air passage 101 and one second air passage 102 of the first air passage component 100a with one first air passage 101 and one second air passage 102 of the second air passage component 100b. That is, only one first air supply pipe 410 and one second air supply pipe 420 need to be installed.

[0068] For example, such as Figure 6As shown, the cabinet 300 can open the cold air duct and return air duct on the front, as well as the cold air duct on the back. At this time, the two second air ducts 102 and one first air duct 101 of the first air duct component 100a need to be connected to the two second air ducts 102 and one first air duct 101 of the second air duct component 100b, that is, two first air supply pipes 410 and one second air supply pipe 420 need to be installed.

[0069] For example, Figure 4 The two first air supply pipes 410 in the air supply pipe assembly 400 can be combined into a first air supply pipe 410 with an increased cross-section. That is, the air supply pipe assembly 400 can include two second air supply pipes 420 and a first air supply pipe 410 with an increased cross-section. One end of the first air supply pipe 410 can be connected to two third air duct openings 105 of the first air duct component 100a at the same time, and the other end of the first air supply pipe 410 can be connected to two third air duct openings 105 of the second air duct component 100b at the same time.

[0070] Furthermore, the first air supply duct 410 and the second air supply duct 420 can be round pipes, square pipes, or pipes with other cross-sectional shapes. This application does not impose any restrictions on this.

[0071] In one embodiment, the fixed frame 110 includes a first frame body 111 and a second frame body 112. A slide rail 113 is provided on the first frame body 111, and a groove 1111 that mates with the slide rail 113 is provided on the second frame body 112. Each of the first frame body 111 and the second frame body 112 defines a placement space. A first air guide 120 and a second air guide 130 are provided within each placement space.

[0072] The air conditioning unit 200 has two cold air inlets and two return air inlets. One of the cold air inlets and one of the return air inlets of the air conditioning unit 200 are connected to the second air duct 102 and the first air duct 101 in the first frame body 111 of the first air duct component 100a, and the other cold air inlet and the other return air inlet of the air conditioning unit 200 are connected to the second air duct 102 and the first air duct 101 in the second frame body 112 of the first air duct component 100a.

[0073] The cabinet 300 has two cold air ducts and two return air ducts. One of the cold air ducts and one of the return air ducts of the cabinet 300 are connected to the second air duct 102 and the first air duct 101 in the first frame 111 of the second air duct component 100b. The other cold air duct and the other return air duct of the cabinet 300 are connected to the second air duct 102 and the first air duct 101 in the second frame 112 of the second air duct component 100b.

[0074] The cooling system for the communication equipment in this embodiment has multiple closed hot and cold air channels, thus achieving higher cooling efficiency.

[0075] Furthermore, one of the cold air ducts and one of the return air ducts of the rack 300 are located on the front of the rack 300, while the other cold air duct and the other return air duct are located on the back of the rack 300. This arrangement allows for the simultaneous supply of cooling energy from different sides of the rack 300, as well as the recovery of heat from different sides of the rack 300, thereby facilitating higher cooling efficiency.

[0076] In some embodiments, such as Figure 7 As shown, there are two air conditioning units 200, each connected to a first air duct component 100a. The cabinet 300 is connected to two second air duct components 100b, located at both ends of the cabinet 300. This arrangement further improves the cooling efficiency for the communication equipment.

[0077] It is understandable that the number of air conditioning units 200 is not limited to two; there can be more, depending on the specific usage requirements.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
