Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, and in particular to an active power distribution network communication device. Background Technology

[0002] In the field of power distribution network communication, communication panels need to process large amounts of data. Existing power distribution network communication devices generally consist of a enclosure and communication equipment housed within it, including a communication panel. The enclosure walls typically have ventilation holes to dissipate heat from the communication equipment. During operation, the communication equipment dissipates heat through these ventilation holes. However, over time, dust accumulates on the communication equipment, affecting its normal operation.

[0003] Some existing enclosures are equipped with cooling fans to improve heat dissipation efficiency and filter structures to filter the airflow generated by the cooling fans. However, the cooling fans increase the amount of air entering the enclosure, so the filter structure needs to be cleaned or replaced frequently, otherwise it will affect the heat dissipation effect on the communication equipment.

[0004] To address this, we provide an active power distribution network communication device that can both improve heat dissipation efficiency and reduce dust ingress into the enclosure. Summary of the Invention

[0005] The purpose of this invention is to provide an active power distribution network communication device in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] An active power distribution network communication device includes communication equipment for power distribution networks and a communication enclosure for installing the communication equipment. The communication enclosure is equipped with a heat dissipation device and a power supply. The communication enclosure is provided with an air inlet and an air outlet. The heat dissipation device includes an intake fan and an exhaust fan. The air outlet of the intake fan is connected to the air inlet. The air inlet of the exhaust fan has two air inlet structures, one of which is connected to the air outlet and the other is connected to the outside. The air flow rate of the exhaust fan per unit time is greater than that of the intake fan per unit time. The air outlet of the exhaust fan is connected to an air outlet assembly through an air pipe.

[0008] The air outlet assembly includes an air hood, which has a first air outlet and a second air outlet that can form an annular air curtain around the air intake fan at the position corresponding to the air intake end of the air intake fan. The inner cavity of the air hood is provided with a vortex tube that can make the airflow in the inner cavity swirl, and the air inlet of the vortex tube is connected to the air inlet of the air hood. The vortex tube has a third air outlet that is connected to the first air outlet and a fourth air outlet that is connected to the second air outlet.

[0009] Preferably, the lower end of the air hood is provided with an inner air outlet hood and an outer air outlet hood spaced apart from the inner air outlet hood. The air inlet of the inner air outlet hood is connected to the third air outlet, and the air inlet of the outer air outlet hood is connected to the fourth air outlet.

[0010] Preferably, both the inner vent hood and the outer vent hood are conical structures.

[0011] Preferably, the taper of the inner air outlet hood busbar is greater than the taper of the outer air outlet hood busbar.

[0012] Preferably, there is an air chamber between the vortex tube and the air shroud, and the vortex tube body is provided with a plurality of air inlets tangent to it at uniform intervals along its circumference.

[0013] Preferably, the top of the communication enclosure is provided with a plurality of mounting holes, and each mounting hole is fitted with a heat dissipation component that penetrates through it.

[0014] Preferably, the top of the communication enclosure is provided with a protective plate located above it.

[0015] The beneficial effects are:

[0016] 1. Due to the design of the air outlet component, the vortex tube uses inertia to allow a large amount of dust and water vapor to enter between the inner air outlet and the outer air outlet, and then be discharged from the second air outlet to form a protective air curtain. This causes the dust and water vapor in the air curtain, as well as the gas around the intake fan, to flow away from the intake fan, effectively reducing the amount of dust and water vapor entering the communication box. This solves the technical problem in the prior art that the filter structure needs to be cleaned or replaced too frequently, otherwise the heat dissipation effect on the communication equipment will be affected.

[0017] 2. Due to the design of the heat sink, the heat dissipation at the top of the communication box can be accelerated, improving the heat dissipation effect. Furthermore, the heat sink, in conjunction with the air venting assembly, can further improve the heat dissipation efficiency of the heat sink and prevent the surface of the heat sink from being covered by dust.

[0018] The additional technical features and advantages of the present invention will become more apparent from the following description, or may be learned through practice of the invention. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] In the description of this invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] Example 1, as Figure 1-5 As shown, an active power distribution network communication device includes a power distribution network communication device 1 and a communication enclosure 2 for installing the communication device 1. The communication enclosure 2 is equipped with a heat dissipation device and a power supply. The communication enclosure 2 is equipped with an air inlet and an air outlet. The heat dissipation device includes an intake fan 3 and an exhaust fan 4. The air outlet of the intake fan 3 is connected to the air inlet. The air inlet of the exhaust fan 4 has two air inlet structures. One air inlet structure is connected to the air outlet, and the other air inlet structure is connected to the outside. The air flow rate of the exhaust fan 4 per unit time is greater than the air flow rate of the intake fan 3 per unit time. The air outlet of the exhaust fan 4 is connected to an air outlet assembly 5 through an air pipe.

[0035] Depending on the requirements, the airflow rate of exhaust fan 4 per unit time is 1.3-1.8 times that of intake fan 3 per unit time, and in this embodiment it is 1.5 times.

[0036] In this embodiment, the air inlet of the communication housing 2 is located in the middle of the top wall of the communication housing 2;

[0037] As needed, such as Figure 3 As shown, the intake fan 3 can be installed inside the communication box 2, so that the air intake end of the intake fan 3 is connected to the air inlet of the communication box 2; the intake fan 3 can also be installed on top of the communication box 2, so that the air outlet end of the intake fan 3 is connected to the air inlet of the communication box 2.

[0038] like Figure 4 As shown, the air outlet assembly 5 includes an air cover 51. The air cover 51 is provided with a first air outlet and a second air outlet that can form an annular air curtain around the air inlet fan 3 at the position corresponding to the air inlet end of the air inlet fan 3.

[0039] Furthermore, the lower end of the air hood 51 is provided with an inner air outlet hood 53 and an outer air outlet hood 54 spaced out from the inner air outlet hood 53. The air inlet of the inner air outlet hood 53 is connected to the third air outlet, and the air inlet of the outer air outlet hood 54 is connected to the fourth air outlet.

[0040] In other words, there is a gas flow chamber between the inner air vent 53 and the outer air vent 54. Specifically, the upper opening between the inner air vent 53 and the outer air vent 54 corresponds to the fourth air outlet of the vortex tube 52, and the lower opening between the inner air vent 53 and the outer air vent 54 forms the second air outlet.

[0041] Specifically, the inner vent 53 and the outer vent 54 are connected by a connector, and the connection does not affect the airflow between the inner vent 53 and the outer vent 54.

[0042] More specifically, multiple connecting rods are evenly spaced around the inner vent 53 and the outer vent 54.

[0043] like Figure 4-5 As shown, the inner cavity of the air hood 51 is provided with a vortex tube 52 that enables the airflow in the inner cavity to swirl. The air inlet of the vortex tube 52 is connected to the air inlet of the air hood 51. The vortex tube 52 has a third air outlet connected to the first air outlet and a fourth air outlet connected to the second air outlet.

[0044] Specifically, the bottom of the swirl tube 52 is connected to the inner cavity of the air shroud 51. The swirl tube 52 has an air chamber between its bottom and the air shroud 51, and the swirl tube 52 has multiple air inlets tangent to it evenly spaced around its circumference.

[0045] In some embodiments, a third air outlet is provided at the center of the bottom surface of the swirl tube 52, and a fourth air outlet is provided along the circumference of the outer edge of the bottom surface of the swirl tube 52.

[0046] In some embodiments, the bottom of the swirling tube 52 is open, and the outer edge of the bottom of the swirling tube 52 corresponds to and cooperates with the outer air hood 54. At this time, the position of the swirling tube 52 on the inner side of the upper end of the inner air hood 53 forms a third air outlet, and the position of the swirling tube 52 on the outer side of the upper end of the inner air hood 53 forms a fourth air outlet.

[0047] During use, the exhaust fan 4 draws in gas from inside the communication box 2 and from the outside. The gas enters the air shroud 51 through the air pipe. The air pipe can be equipped with heat dissipation fins as needed, and can be divided into two sections with a heat exchange device between them. Then, the airflow inside the air shroud 51 enters the vortex tube 52, where it swirls within the tube. Because the weight of dust and water vapor in the gas is greater than the weight of the gas molecules, and due to inertia, the dust and water vapor are located on the periphery of the gas and are discharged through the fourth outlet between the inner air shroud 53 and the outer air shroud 54, before being discharged through the second outlet. The airflow from the second outlet forms an air curtain, causing the gas around the intake fan 3 to flow outward, preventing dust and moisture in the gas around the intake fan 3 from entering the intake fan 3. The gas inside the inner cavity of the vortex tube 52 is relatively pure gas, meaning that very little dust and moisture is mixed in with this gas. It enters the inner cavity of the inner exhaust hood 53 through the third outlet and then exits through the first outlet. Since the first outlet corresponds to the air intake end of the intake fan 3, this part of the gas is absorbed by the intake fan 3 and enters the communication housing 2 to dissipate heat from the communication equipment 1, ensuring that the communication equipment 1 does not experience high temperatures and reducing the amount of dust covering the surface of the communication equipment 1.

[0048] In some embodiments, the inner exhaust hood 53 and the outer exhaust hood 54 are cylindrical structures, wherein the inner diameter of the inner exhaust hood 53 is larger than the diameter of the air intake end of the air intake fan 3.

[0049] In some embodiments, such as Figure 4 As shown, in order to reduce the size of the inner exhaust hood 53 and the outer exhaust hood 54, both the inner exhaust hood 53 and the outer exhaust hood 54 are conical structures; this makes the gas discharged from the second exhaust port form a conical air curtain, ensuring that the gas around the intake fan 3 containing dust and water vapor flows to the side away from the intake fan 3, preventing this part of the gas from being in a turbulent state around the intake fan 3.

[0050] Specifically, such as Figure 4 As shown, the taper of the inner air outlet hood 53 is greater than that of the outer air outlet hood 54; this results in a larger flow velocity of the airflow discharged from the second air outlet, making the air curtain stronger and further enhancing its effect.

[0051] Example 2, based on Example 1, such as Figure 1 As shown, Figure 1As shown, the top of the communication box 2 is provided with multiple mounting holes, and each mounting hole is fitted with a heat sink 6 that penetrates through it.

[0052] Because there are dead zones of hot gas inside the communication box 2, especially at the top corners of the inner cavity of the communication box 2, the heat sink 6 can dissipate the high temperature of this part. At the same time, the gas discharged from the second vent flows towards the heat sink 6, so the heat inside the heat sink 6 and the dust on the surface of the heat sink 6 can be carried away, ensuring the normal operation of the heat sink 6.

[0053] Example 3, based on Example 1, such as Figure 1-3 As shown, to prevent rainwater from wetting the intake fan 3 and the exhaust assembly 5, a protective plate 7 is provided on the top of the communication housing 2; specifically, the protective plate 7 is located above the exhaust assembly 5.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
