Description

Technical Field

[0001] The invention relates to the field of heat dissipation of electronic devices, and in particular to a cabinet door and a cabinet component. Background Art

[0002] With the rapid development of electronic technology, the line rate of equipment has increased significantly, and the power consumption of single-machine equipment has also increased by leaps and bounds. The power consumption of a single rack with full configuration has increased exponentially. With the increase in equipment integration and cross-capacity, the power consumption of the entire computer room system has also increased significantly, and the heat dissipation problem of the cabinet equipment inside the computer room needs to be solved urgently.

[0003] However, the inventor of the present invention found that the cold pooling of the aisles of the cabinet equipment in the prior art cannot solve the problem of mixing of cold and hot airflows when dissipating heat. A cabinet has multiple air inlets and multiple air outlets mixed together, resulting in the hot airflow discharged from the inside of the cabinet being sucked into the inside of the cabinet again, seriously affecting the heat dissipation efficiency of the cabinet equipment. In order to solve this technical problem, either the equipment cabinet structure is thoroughly optimized and transformed, but the feasibility of transforming the equipment cabinet structure is relatively difficult; or an auxiliary air guide cabinet is added outside the equipment cabinet, but the addition of the air guide cabinet will occupy the space of the computer room, reducing the space utilization rate of the computer room, and the addition of the air guide cabinet is not suitable for the transformation of the old computer room. Therefore, how to improve the heat dissipation efficiency of the cabinet has become an urgent problem to be solved. Summary of the invention

[0029] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0030] The first embodiment of the present invention relates to a cabinet door, the specific structure of which is as follows Figure 1 , Figure 2 As shown, it includes: a main body 10 used to be set on the cabinet to close the internal space of the cabinet, the main body 10 surrounds a cavity 11 for communicating with the internal space of the cabinet; an isolation plate 20 is set in the cavity 11, the isolation plate 20 divides the cavity 11 into an air inlet cavity 110 and an air outlet cavity 120 isolated from each other; the air inlet cavity 110 is used to provide an air inlet channel for the cooling airflow entering the internal space of the cabinet from the outside of the cabinet, that is, the cooling airflow outside the cabinet is transmitted to the internal space of the cabinet via the air inlet cavity 110, the cooling airflow cools and exchanges heat for the electronic devices in the internal space of the cabinet, and discharges the hot airflow; the air outlet cavity 120 is used to provide an air outlet channel for the hot airflow discharged from the internal space of the cabinet to the outside of the cabinet, that is, the hot airflow generated in the internal space of the cabinet is transmitted to the outside of the cabinet via the air outlet cavity 120.

[0031] Compared with the prior art, the main body 10 of the cabinet door provided in the first embodiment of the present invention is surrounded by a cavity 11, and the cavity 11 is connected to the internal space of the cabinet. The hot air flow generated in the cabinet is discharged and enters the cavity 11. In this embodiment, an isolation plate 20 is arranged in the cavity 11, and the cavity 11 is divided into an air inlet cavity 110 and an air outlet cavity 120 that are isolated from each other by the isolation plate 20. The cooling air flow outside the cabinet is transmitted to the internal space of the cabinet through the air inlet cavity 110. Since there is an air inlet air flow in the air inlet cavity 110, the cabinet When the hot air in the cabinet is discharged and enters the cavity 11, it can only enter the air outlet cavity 120 and be discharged to the outside of the cabinet through the air outlet cavity 120. Since an isolation plate 20 is provided between the air inlet cavity 110 and the air outlet cavity 120, the hot air in the cabinet will not enter the internal space of the cabinet again with the air inlet air flow after entering the air outlet cavity 120, thereby effectively reducing the temperature of the cooling air flow sucked into the cabinet, and avoiding the air flow turbulence that may be generated when the hot air flow and the cold air flow collide and mix with each other, thereby effectively improving the heat dissipation efficiency of the cabinet. In addition, the cabinet door provided in this embodiment can be installed on the cabinet to effectively improve the heat dissipation effect of the cabinet, is easy to install, occupies a small area, and does not require any modification of the cabinet itself and the computer room, thereby effectively improving the scope of application of the cabinet door.

[0032] Specifically, in the present embodiment, the isolation plate 20 is fixed on the main body 10, and the position of the isolation plate 20 on the main body 10 is adjustable. Since the positions of electronic devices in different cabinets are different, the position of the isolation plate 20 on the main body 10 is adjustable. When the position of the isolation plate 20 is adjusted, the positions of the air inlet cavity 110 and the air outlet cavity 120 also change accordingly, and the air outlet cavity 120 can always be arranged in correspondence with the electronic device, that is, the air outlet cavity 120 is arranged at the position where the hot air of the electronic device is discharged, so as to adapt to the different positions of electronic devices in different cabinets, and further improve the scope of application of the cabinet door. It can be understood that, if Figure 1 , Figure 2 The two isolation plates 20 shown in the vertical direction of the cabinet door are arranged to separate the cavity 11 into two air outlet cavities 120 and one air inlet cavity 110 arranged vertically. This is only a specific example of the present embodiment and does not constitute a limitation. In other embodiments of the present invention, the isolation plates 20 can also be arranged in the horizontal direction or obliquely upward of the cabinet door. They are not listed here one by one, and can be flexibly arranged according to actual needs.

[0033] Specifically, in this embodiment, a plurality of isolation plate support frames 30 are disposed on the main body 10. For example, two isolation plate support frames 30 are vertically disposed on both sides of the cabinet door. Fixing members 31 are respectively disposed on the two vertically disposed isolation plate support frames 30. The isolation plate 20 is disposed on the two vertically disposed fixing members 31. Figure 3FIG. 1 is a schematic structural diagram of a specific embodiment of an isolation plate support frame 30. The isolation plate support frame 30 includes a plurality of mutually spaced fixing members 31. In this embodiment, a groove is provided on the fixing member 31. The fixing member 31 is used to fix the isolation plate 20. Figure 4 The structure of an isolation plate 20 provided in the present embodiment is shown, including an isolation portion 21 for isolating the cavity 11 to form an air outlet cavity 120 and an air inlet cavity 110, and a fixing portion 22 for fixing to a fixing member 31. In the present embodiment, the fixing member 22 is inserted into a groove on the fixing member 31, so as to achieve connection and fixation between the isolation plate 20 and the fixing member 31. Since the isolation plate support frame 30 includes a plurality of fixing members 31, the isolation plate 20 can be selectively fixed to fixing members 31 at different positions, and after the isolation plate 20 is set on the fixing member 31, it can be disassembled and selectively fixed to other fixing members 31 again, so as to achieve adjustable position of the isolation plate 20 on the main body 10. It can be understood that Figure 3 and Figure 4 The figure is only an example of a specific structure of the isolation plate support frame 30 and the isolation plate 20 in this embodiment, and does not constitute a limitation. It can be understood that, if Figure 1 , Figure 2 The two isolation plate support frames 30 shown on the left and right sides of the cabinet door in the vertical direction are only a specific example of this embodiment. In other embodiments of the present invention, the isolation plate support frames 30 can also be horizontally or obliquely arranged on the main body 10, which are not listed one by one here.

[0034] Specifically, in this embodiment, it also includes a power component 40 disposed on the main body 10 and connected to the air inlet cavity 110, and the power component 40 is used to draw the cooling airflow outside the cabinet into the air inlet cavity 110. The power component 40 is arranged to draw the external cooling airflow into the air inlet cavity 110, and form an airflow toward the inside of the cabinet in the air inlet cavity 110, so as to prevent the hot air in the cabinet from entering the air inlet cavity 110. In addition, the power component 40 can accelerate the external cooling airflow to enter the cabinet, and increasing the ventilation volume of the cabinet can enhance the heat dissipation effect of the cabinet. Further, as Figure 5 As shown, in this embodiment, the power part 40 is a fan. Since the speed of the fan 40 is adjustable, the air intake volume and air intake speed of the cooling airflow input into the cabinet can be flexibly adjusted for communication equipment with different heat generation, thereby improving the applicability of the cabinet door. It can be understood that the aforementioned power part 40 being a fan is only a specific example of this embodiment and does not constitute a limitation. In other embodiments of the present invention, the power part 40 may also be other structures such as a miniature air conditioner.

[0035] Specifically, in this embodiment, the power member 40 is fixed on the main body 10, and the position of the power member 40 on the main body 10 is adjustable. That is, the power member 40 is fixed on the main body 10 after installation, and the installation position of the power member 40 can be selectively set during the installation process, and the position of the power member 40 after installation can be reset. The position of the power member 40 on the main body 10 is adjustable, so as to adapt to different models of cabinets and improve the application range of the cabinet door.

[0036] Specifically, in this embodiment, there are multiple power members 40, and there are multiple isolation plates 20, and isolation plates 20 are respectively provided on the upper and lower sides of the power members 40. It can be understood that the isolation plates 20 are respectively provided on the upper and lower sides of each of the power members 40 is only a specific example of this embodiment, and does not constitute a limitation. In other embodiments of the present invention, other structures such as isolation plates 20 may also be provided on one side of the power member 40.

[0037] Specifically, in this embodiment, an air inlet 14 is provided on the main body 10 and communicates with the air inlet cavity 110, and an air outlet 15 is provided on the main body 10 and communicates with the air outlet cavity 120, wherein the angle between the direction of the air inlet 14 and the direction of the air outlet 15 is greater than 45 degrees. For example, in this embodiment, the air inlet 14 is provided on the front plate 12 corresponding to the ventilation plate 112, and the air outlet 15 is provided on the side plate 13. The angle between the direction of the air inlet 14 and the direction of the air outlet 15 is greater than 45 degrees, thereby preventing the hot air discharged from the air outlet 15 to the outside of the cabinet from being sucked into the cabinet again from the air inlet 14. It can be understood that the angle between the direction of the air inlet 14 and the direction of the air outlet 15 being greater than 45 degrees is only a specific example in the present embodiment and is not limiting. In other embodiments of the present invention, the distance between the air inlet 14 and the air outlet 15 may be set to be far enough, and other structures may be used. For example, the air inlet 14 is set at the bottom of the front panel, and the air outlet 15 is set at the top of the front panel.

[0038] Specifically, in this embodiment, a spare exhaust port 130 is provided on the side plate 13 and a switch assembly 140 is provided on the spare exhaust port 130. The spare exhaust port 130 is communicated with the air outlet cavity 120. The spare exhaust port 130 can be provided so that when the air outlet 15 fails, such as being blocked, the switch assembly 140 is opened, so that the spare exhaust port 130 replaces the air outlet 15 to discharge hot air.

[0039] Specifically, in the present embodiment, an airflow channel 50 is further included, which is provided on the main body 10, and is used to connect the air outlet cavity 120 to the air outlet 15. The airflow channel 50 is provided on the main body 10, and the airflow channel 50 connects each air outlet cavity 120 and the air outlet 15, so as to collect the hot air in each air outlet cavity 120 and discharge it uniformly through the air outlet 15, so as to avoid the hot air in multiple air outlet cavities 120 being re-absorbed into the cabinet after the hot air is discharged from different positions of the cabinet door, so as to prevent the cold and hot air flows from mixing and increasing the temperature of the cold air flow entering the cabinet to cool the cabinet, and further improve the cooling efficiency of the cabinet.

[0040] Specifically, in this embodiment, the airflow channel 50 is arranged at the side of the main body 10. Since the electronic components in the cabinet are usually arranged in the center of the cabinet, the airflow channel 50 is arranged at the side of the main body 10 to avoid the airflow channel 50 affecting the heat dissipation of the electronic components in the cabinet, and further improve the heat dissipation efficiency of the cabinet.

[0041] Specifically, the airflow channel 50 includes a plurality of openings 51 and a first cover plate 52 disposed on each opening 51, and the first cover plate 52 can be selectively opened and / or closed. A plurality of first cover plates 52 are disposed on the airflow channel 50, and the first cover plates 52 can be selectively opened and / or closed, so that the first cover plates 52 can be opened and / or closed according to the position of the air outlet cavity 120, and the airflow channel 50 is controlled to be connected with the air outlet cavity 120 and closed with the air inlet cavity 110. For example Figure 1 As shown, when the position of the air inlet cavity 110 changes so that the first cover plate 52 is in the air inlet cavity 110, the first cover plate 52 in the air inlet cavity 110 is in a closed state, and the first cover plate 52 in the air outlet cavity 120 is in an open state. By selectively opening and closing the first cover plate 52, the air flow channel 50 is controlled to communicate with the air outlet cavity 120 and be closed with the air inlet cavity 110.

[0042] It is to be understood that the above is only a specific example of the air flow channel in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the air flow channel 50 may also be as follows: Figure 6The structure shown, i.e., the airflow channel 50 includes a slot 53, a plurality of second cover plates 54 movably covered on the slot 53, and the plurality of second cover plates 54 are spaced apart from each other to form an opening 51. The second cover plate 54 is movably arranged on the slot 53, and the second cover plate 54 can be moved according to the position of the air outlet cavity 120, thereby moving the position of the opening 51, so as to ensure that the airflow channel 50 is connected with the air outlet cavity 120 and isolated from the air inlet cavity 140. It can be understood that the aforementioned plurality of second cover plates 54 are spaced apart from each other to form the opening 51 is only a specific example of the present embodiment, and does not constitute a limitation. In other embodiments of the present invention, other methods such as the second cover plate 54 and the slot 53 are spaced apart from each other to form the opening 51 can also be used.

[0043] Please continue to refer to Figure 1 and Figure 2 Specifically, in this embodiment, the main body 10 includes a front plate 12, a side plate 13 disposed at the side edge of the front plate 12 and forming the cavity 11 together with the front plate 12, and the front plate 12 includes a blind plate 121 and a ventilation plate 122 disposed in contact with each other. Figure 7 As shown, the blind plate 121 is a dense plate-like structure; Figure 8 As shown, the ventilation plate 122 is a porous structure, thereby achieving a ventilation effect.

[0044] Specifically, the positions of the blind plate 121 and the ventilation plate 122 are adjustable. For example, the ventilation plate 122 can change its position as the position of the power part 40 changes, and the ventilation plate 122 is kept corresponding to the power part 40. For example, in this embodiment, the ventilation plate 122 can be set at a position corresponding to the front plate 12 and the power part 40, ensuring that the power part 40 can inhale gas into the air inlet cavity 110 through the ventilation plate 122; in addition, the ventilation plate 122 is set at a position corresponding to the front plate 12 and the power part 40, which can prevent the power part 40 from inhaling large-sized debris from the outside into the cabinet, protect the power part 40 and the cabinet, and improve the service life of the cabinet door and the cabinet as a whole. In addition, in this embodiment, the air outlet cavity 120 is connected to the air outlet 15 via the air flow channel 50. Therefore, in addition to the air outlet 15, the blind plate 121 is set at other positions of the air outlet cavity 120 to close the air outlet cavity 120, so as to prevent the air outlet cavity 120 from dissipating heat outward from other positions. It can be understood that the aforementioned setting of the blind plate to close the air outlet cavity 120 is only a specific example of the present embodiment and does not constitute a limitation. In other embodiments of the present invention, a ventilation plate 122 can also be set at the position of the air outlet cavity 120, and it can be flexibly set according to actual needs.
