DETAILED DESCRIPTION

[0031] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0033] At present, the electrical components inside the communication cabinet will generate a lot of heat when working, so it is necessary to use air conditioners, fans, etc. to dissipate heat to meet the heat dissipation requirements of the communication cabinet.

[0034] The inventor of the present application has found that if air conditioning is used to dissipate heat from a communication cabinet, a large investment is required. Therefore, fans are generally used to dissipate heat from communication cabinets. However, the fan installed in the communication cabinet has a limited heat dissipation range, and can only achieve a good heat dissipation effect in some areas of the communication cabinet near the air inlet side or the exhaust side of the fan, but cannot achieve a good heat dissipation effect in the entire communication cabinet.

[0035] In order to solve the problems in the prior art, the embodiments of the present application provide a heat dissipation device and a communication cabinet, which are described in detail below with reference to the accompanying drawings.

[0036] Figure 1 A schematic diagram of the structure of a heat dissipation device provided in an embodiment of the present application; Figure 2 A schematic structural diagram of a heat dissipation device provided in an embodiment of the present application from another perspective; Figure 3 for Figure 2 A schematic diagram of the enlarged structure at A in the middle; Figure 5 A schematic diagram of the internal structure of a communication cabinet provided in an embodiment of the present application; Figure 6 for Figure 5 Schematic diagram of the enlarged structure at point B in the middle.

[0037] See also Figures 1 to 3 ,as well as Figure 5 and 6The embodiment of the present application provides a heat dissipation device 100, including a first protective cover, a first fan 11 and a driving assembly, wherein a first accommodating space is provided inside the first protective cover, and the first protective cover is also provided with a first heat dissipation port 16 and at least one first ventilation hole 5 connected to the first accommodating space, the first heat dissipation port 16 is used to be connected to the ventilation port 14 of the communication cabinet; the first fan 11 is located in the first accommodating space, the first fan 11 has a first air inlet and a first air outlet, the first fan 11 is used to transport air from the first air inlet to the first air outlet, one of the first air inlet and the first air outlet faces the first heat dissipation port 16, and the other is connected to the first ventilation hole 5 through a part of the first accommodating space; the driving assembly is installed in the first accommodating space, and the driving assembly is used to drive the first fan 11 to reciprocate along a first direction, and the first direction is parallel to the plane where the first heat dissipation port 16 is located.

[0038] When the first air inlet faces the first heat dissipation port 16, the first fan 11 is used to transport the air with a higher temperature inside the communication cabinet to the outside of the communication cabinet and the heat dissipation device 100 through the ventilation port 14, the first heat dissipation port 16, the first air inlet, the first air exhaust port and the first ventilation hole 5 in sequence, so as to avoid the internal temperature of the communication cabinet being too high. Since the air flow rate in the internal area of ​​the communication cabinet directly facing the first air inlet is relatively fast, the internal area of ​​the communication cabinet directly facing the first air inlet has a higher heat dissipation efficiency. When the first air outlet faces the first heat dissipation port 16, the first fan 11 is used to transport the air with a lower temperature outside the first ventilation hole 5 to the inside of the communication cabinet through the first ventilation hole 5, the first air inlet, the first air exhaust port, the first heat dissipation port 16 and the ventilation port 14 in sequence, so as to cool down the electrical components with a higher temperature inside the communication cabinet. Since the air flow rate in the internal area of ​​the communication cabinet directly facing the first air exhaust port is relatively fast, the internal area of ​​the communication cabinet directly facing the first air inlet has a higher heat dissipation efficiency.

[0039] For either of the above two situations, during the rotation of the first fan 11, the driving assembly drives the first fan 11 to reciprocate as a whole along the first direction, so that the area with higher heat dissipation efficiency inside the communication cabinet can alternately reciprocate along the first direction, thereby improving the heat dissipation range of the first fan 11 as a whole, so that the interior of the communication cabinet as a whole can achieve better heat dissipation effect; since the first fan 11 and the driving assembly are installed in the first accommodating space, the first protective cover can provide better protection for the first fan 11 and the driving assembly; in addition, the ventilation opening 14 of the communication cabinet is generally large in area. By setting a protective cover, while the heat dissipation device 100 realizes the heat dissipation function, it can provide better protection for the electrical components in the communication cabinet, preventing unauthorized operators from operating the switches and other electrical components inside the communication cabinet through the ventilation opening 14.

[0040] In some embodiments, multiple first fans 11 are arranged at intervals along the second direction, the second direction intersects with the first direction and is parallel to the plane where the first heat dissipation port 16 is located, and multiple first fans 11 working simultaneously can further improve the overall heat dissipation efficiency of the heat dissipation device 100.

[0041] In some embodiments, the second direction is perpendicular to the first direction, which can avoid a large heat dissipation dead angle when the multiple first fans 11 reciprocate along the first direction, thereby further improving the overall heat dissipation efficiency of the heat dissipation device 100.

[0042] In some embodiments, the driving assembly includes: a slide 8, which is slidably connected to the first protective cover along a first direction, and a first fan 11 is installed on the slide 8; a first driver 4, which is used to drive the slide 8 to reciprocate along the first direction. Specifically, the first driver 4 can be a linear driver such as a linear module and a cylinder. After the first fan 11 is installed on the slide 8, it is slidably connected to the first protective cover through the slide 8. In the process of the first driver 4 driving the slide 8 to slide, the first fan 11 and the slide 8 have high operating stability.

[0043] In some embodiments, a fixed frame 6 is fixed in the first protective cover, and the driving assembly also includes a screw rod 10 parallel to the first direction, one end of the screw rod 10 is rotatably connected to the fixed frame 6, and the threaded section of the screw rod 10 is threadedly connected to one side of the slide 8. The first driver 4 includes a motor for driving the screw rod 10 to rotate. Through the transmission of the screw rod 10, a higher transmission accuracy can be achieved, and the operation has higher stability.

[0044] In some embodiments, the fixed frame 6 is fixed with a slide bar 9 parallel to the first direction, and the other side of the slide 8 is slidably connected to the slide bar 9, which has a simple structure and low implementation cost. In addition, the cross section of the slide bar 9 can be circular, which is easy to process, and the slide bar 9 cooperates with the screw rod 10, which can also better limit the moving direction of the slide 8, so that the slide 8 can only move along the first direction.

[0045] In some embodiments, the screw rod 10 and the slide rod 9 are spaced apart along the second direction. Along the second direction, the communication cabinet itself has a certain length. By limiting the distribution direction of the screw rod 10 and the slide rod 9 to the second direction, the heat dissipation device 100 as a whole can be prevented from occupying a large space in a direction perpendicular to both the first direction and the second direction, thereby making the overall appearance of the communication cabinet and the heat dissipation device 100 more compact.

[0046] In some embodiments, the first protective cover includes a first top plate 1, a first bottom plate 3 and at least one first side plate 2 connected between the first top plate 1 and the first bottom plate 3. The first accommodating space is surrounded by the first top plate 1, the first bottom plate 3 and the first side plate 2. The first top plate 1 and the first bottom plate 3 are spaced apart along a first direction. A plurality of first ventilation holes 5 are evenly distributed on the first side plate 2 and / or the first bottom plate 3, which can provide better protection for the interior of the first accommodating space and the interior of the communication cabinet. By setting a plurality of first ventilation holes 5, a relatively good heat dissipation effect can be achieved.

[0047] In some embodiments, the first top plate 1 gradually tilts toward the first bottom plate 3 from the direction of the first heat dissipation opening 16 pointing toward the first accommodation space, which can prevent water from accumulating on the top of the first top plate 1 in rainy weather.

[0048] In some embodiments, the fixing frame 6 is fixed to the first side plate 2 near the first top plate 1, the end of the screw rod 10 away from the fixing frame 6 is rotatably connected to the first bottom plate 3, and the end of the slide rod 9 away from the fixing frame 6 is fixed to the first bottom plate 3, so that there is a large area between the fixing frame 6 and the first bottom plate 3 for the first motor to reciprocate, thereby achieving a relatively good heat dissipation effect. In addition, both ends of the screw rod 10 and the slide rod 9 are provided with a connection structure, which can improve the structural stability of the two, thereby further improving the operating stability of the drive assembly.

[0049] In some embodiments, the heat dissipation device 100 further includes: a buffer assembly 7, two buffer assemblies 7 are respectively installed on the side of the fixed frame 6 facing the slide 8 and the side of the first bottom plate 3 facing the slide 8, and when the slide 8 moves to press against one of the buffer assemblies 7, the corresponding buffer assembly 7 is used to provide elastic force to the slide 8 in a direction away from the corresponding buffer assembly 7. Specifically, the buffer assembly 7 can be a spring, a buffer pad made of silicone, or other elastic element, which can have a good buffering effect on the slide 8, and reduce the risk of damage to the slide 8 and the first fan 11 due to collision with the fixed frame 6 and the first bottom surface during movement in the first direction.

[0050] In some embodiments, the heat dissipation device 100 also includes: a first filter 15, which is covered and installed on the first heat dissipation port 16, and can filter the air entering the interior of the communication cabinet through the first heat dissipation port 16, to prevent dust and other impurities from entering the interior of the communication cabinet, to prevent dust and other impurities from adhering to electrical components, and to ensure the heat dissipation effect and normal operation of the electrical components.

[0052] like Figures 4 to 8 As shown, the embodiment of the present application also provides a communication cabinet, including the heat dissipation device 100 in the above embodiment, and also including: a cabinet, a second accommodating space for accommodating electrical components is provided inside the cabinet, the second accommodating space is surrounded by a second top plate 22, a second bottom plate, and a plurality of second side plates connected between the second top plate 22 and the second bottom plate, the second top plate 22 is arranged opposite to the second bottom plate, at least one second side plate is provided with a vent 14, a heat dissipation device 100 is installed at each vent 14 position, and the vent 14 is connected to the corresponding first heat dissipation port 16. Since the communication cabinet includes the heat dissipation device 100 in the above embodiment, it has at least all the beneficial effects brought by the above embodiment, which will not be repeated here.

[0053] In some embodiments, the second top plate 22 is provided with a top air vent 21 connected to the second accommodating space, and the communication cabinet also includes an auxiliary ventilation device 200, which includes: a second fan 24, at least one second fan 24 is installed near the top air vent 21; a third top plate 17, located on the side of the top air vent 21 facing away from the second accommodating space; a third side plate 18, fixedly connected between the third top plate 17 and the second top plate 22, and a plurality of third side plates 18 connected end to end are distributed around the top air vent 21, and the third side plate 18 is provided with a second ventilation hole 19 connected to the top air vent 21, and along the direction perpendicular to the second top plate 22, the projections of the top air vent 21 and the third side plate 18 are both located within the projection range of the third top plate 17. By setting the auxiliary ventilation device 200 on the second top plate 22, a wider heat dissipation range can be achieved, thereby improving the overall heat dissipation effect of the communication cabinet; in addition, the third top plate 17 can prevent rainwater from entering the second accommodating space through the top air vent 21, thereby providing better protection for the electrical components in the second accommodating space; by setting the third side plate 18 and the second ventilation hole 19, the ventilation effect of the top air vent 21 can be guaranteed, and unauthorized operators can be prevented from operating electrical components such as switches in the second accommodating space through the top air vent 21.

[0054] In some embodiments, the auxiliary ventilation device 200 further includes: an adapter frame 23, which is fixedly installed at a position of the second accommodating space near the top air outlet 21, and a second fan 24 is fixedly installed on the adapter frame 23; and a second filter screen 20, which is installed to cover the top air outlet 21. By setting the adapter frame 23, the second fan 24 can be better fixed, and by setting the second filter screen 20, the air entering the communication cabinet through the top air outlet 21 can be filtered, which can further ensure the heat dissipation effect and normal operation of the electrical components.

[0055] In some embodiments, the outer edge of at least one side of the third top plate 17 is provided with a bending portion inclined toward the second top plate 22, which can drain rainwater on the top of the third top plate 17 to the second top plate 22 and prevent rainwater on the top of the third top plate 17 from flowing into the second ventilation hole 19 along the third top plate 17.

[0056] In some embodiments, the cabinet body further includes an inspection port connected to the second accommodating space, and the communication cabinet further includes: a cabinet door 12, which is opened and closed at the inspection port, and the cabinet door 12 is provided with at least one third ventilation hole 13, which can further improve the heat dissipation effect.

[0057] In some embodiments, each of the first motor and the second motor is used to introduce the air with a lower temperature outside the communication cabinet into the second accommodation space. The air introduced into the second accommodation space performs heat exchange on the electrical components inside the communication cabinet and is output to the outside through the third ventilation hole 13. While having a high heat dissipation effect, the first filter 15 and the second filter 20 can both have a good filtering effect to ensure the normal operation of the electrical components.

[0058] In some embodiments, the inspection port is located between the second top plate 22 and the second bottom plate, and the third ventilation hole 13 is located in the area of ​​the cabinet door 12 close to the second bottom plate. The auxiliary ventilation device 200 is located far away from the third ventilation hole 13, so the air introduced into the second accommodation space through the top air vent 21 has a relatively long flow path in the second space, so that sufficient heat exchange can be performed with the electrical components inside the communication cabinet, which can further improve the heat dissipation effect.

[0059] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this.
