Description

Technical Field

[0001] This application relates to the field of waterproofing and heat dissipation, and in particular to a waterproof airflow guide plate, a waterproof heat dissipation component, and a waterproof heat dissipation cabinet. Background Technology

[0002] Generally, outdoor waterproof enclosures employ external partitions or a "box-within-a-box" design. In this structural design, a protective panel is directly covered to the areas with openings on the outside of the enclosure, or the outer panels are connected to form a "box-within-a-box" structure, thereby preventing rainwater from entering the enclosure. However, this design has many drawbacks.

[0003] On the one hand, while it can prevent rainwater from entering to some extent, it greatly affects the heat dissipation of the heat-generating modules inside the chassis. Due to the presence of the shield, smooth convection cooling is difficult to achieve, causing the heat-generating modules to overheat during operation, affecting the normal operation of the charging station. At the same time, the cooling fan operates less efficiently under these conditions and generates high-decibel noise, interfering with the surrounding environment.

[0004] On the other hand, in terms of appearance and chassis size, the installation of related shields will increase the size and weight of the chassis, not only taking up more space but also increasing the difficulty of installation and transportation. Moreover, the visual appearance will be difficult to meet the requirements of the product's industrial design. Summary of the Invention

[0005] To address the problems in the prior art, this application provides a waterproof guide plate.

[0006] In addition, this application also provides a waterproof heat dissipation assembly with waterproof guide plates.

[0007] In addition, this application also provides a waterproof heat dissipation cabinet having the waterproof heat dissipation component.

[0008] A waterproof flow guide plate for blocking target objects in a fluid includes a body and a baffle. The body includes a first end and a second end disposed opposite each other, defining the flow direction from the first end to the second end. The baffle is connected to the second end of the body and is configured to block target objects in the fluid flowing along the flow direction. The angle between the baffle and the second end is 60 to 120 degrees. The first end has a notch configured to allow target objects to drain out.

[0009] In some possible implementations, the angle between the baffle and the body is 60 to 120 degrees.

[0010] In some possible implementations, the cross-sectional width of the first end is greater than the cross-sectional width of the second end along the direction perpendicular to the flow direction.

[0011] In some possible implementations, the body is provided with a fixing groove, one end of which is connected to the notch, and the fixing groove is configured to limit the waterproof guide plate.

[0012] In some possible implementations, along a direction perpendicular to the flow direction, opposite ends of the baffle protrude from the second end to form limiting blocks, the limiting blocks being configured to limit the waterproof flow guide plate.

[0013] A waterproof heat dissipation assembly includes: a plurality of waterproof guide plates, a mounting plate, and a first cover. The mounting plate is provided with a plurality of angled slots at intervals, each angled slot extending in the same direction, and the waterproof guide plates are inserted into the angled slots. The first cover surrounds the mounting plate and the plurality of waterproof guide plates on the outside.

[0014] In some possible implementations, a first housing and a first frame are also included, the first housing being connected to the first frame to enclose an installation space, and the first cover being disposed in the installation space.

[0015] In some possible implementations, a fluid drive is also included, which is connected to the first housing and is used to drive fluid to flow in or away from the flow direction.

[0016] In some possible implementations, a second cover and a second housing are also included, the second cover being connected to the second housing to enclose and form a second mounting space, the fluid drive being disposed in the second mounting space, and the second mounting space communicating with the first mounting space.

[0017] In some possible implementations, a second frame is also included, which is foldably connected to the first frame and the second housing.

[0018] In some possible implementations, a filter element is also included, which is disposed between the fluid drive element and the plurality of waterproof guide vanes.

[0019] A waterproof heat dissipation cabinet includes a cabinet body and a waterproof heat dissipation component as described above. The cabinet body has a window, and the waterproof heat dissipation component is rotatably connected to the cabinet body and configured to cover the window.

[0020] The waterproof airflow guide provided in this application includes a main body and a baffle inclinedly connected to a second end. The baffle blocks target objects (such as rainwater, ice, and dust) in the fluid, while the first end has a notch for the discharge of these target objects. This design allows for smooth airflow, ensuring excellent heat dissipation, while effectively blocking and expelling the target objects. It eliminates the need for additional baffles or complex structures, solving the problems of poor heat dissipation and excessive size in the prior art. It achieves a balance between waterproofing and dustproofing with efficient heat dissipation, reduces noise, optimizes cabinet dimensions, and improves the overall performance of the product.

[0030] Please see Figure 1 One embodiment of this application provides a waterproof heat dissipation cabinet 100, which is applied to an outdoor charging pile system. In other embodiments, the waterproof heat dissipation cabinet 100 can be applied to signal transmission equipment of communication base stations, outdoor meteorological monitoring station equipment, outdoor multimedia playback equipment cabinets in public places such as parks or squares, outdoor lighting control system cabinets in cities, and automated production monitoring equipment cabinets in open-air factories.

[0031] In this embodiment, the waterproof heat dissipation cabinet 100 includes a cabinet body 10 and at least two waterproof heat dissipation components 20. Correspondingly, the cabinet body 10 is provided with at least two openings 101, and each opening 101 is provided with a waterproof heat dissipation component 20. The waterproof heat dissipation component 20 facilitates heat exchange between the interior of the cabinet body 10 and the external environment.

[0032] In this embodiment, there are two waterproof heat dissipation components 20, one for allowing cold air from the outside environment to enter the cabinet 10, and the other for allowing hot air from inside the cabinet 10 to enter the outside environment. In other embodiments of this application, there may be three or more waterproof heat dissipation components 20, at least one for allowing cold air from the outside environment to enter the cabinet 10, and at least one for allowing hot air from inside the cabinet 10 to enter the outside environment.

[0033] Please see Figures 2 to 7The waterproof heat dissipation assembly 20 includes a mounting plate 21, a first cover 22, and a plurality of waterproof air guide plates 23. The first cover 22 is generally frame-shaped, and the mounting plate 21 is disposed inside the first cover 22. The mounting plate 21 has an extending direction A, and along the extending direction A, a plurality of waterproof air guide plates 23 are arranged side by side at intervals on the mounting plate 21. A channel T is defined between each two adjacent waterproof air guide plates 23, and the channel T allows for heat exchange between hot air inside the cabinet and cold air in the external environment.

[0034] Please see Figure 6 and Figure 7 In this embodiment, each waterproof guide plate 23 is generally hook-shaped, and includes a body 231 and a baffle 232. The body 231 includes a first end 231a and a second end 231b disposed opposite to each other. The direction from the first end 231a to the second end 231b is defined as the flow direction B. Air can flow in the channel T along the flow direction B. The flow direction B is inclined to the extension direction A of the mounting plate 21. The baffle 232 is inclined to the second end 231b. That is, the baffle 232 is inclined to the flow direction B, and the baffle 232 is used to block target objects such as water, ice, and dust in the air. The first end 231a is provided with a notch 233, and multiple notches 233 are correspondingly arranged along the extension direction A. Since the flow direction B is inclined to the extension direction A, the target objects blocked by the baffle 232 can be discharged from the channel T through the notch 233.

[0035] In this embodiment, along the vertical flow direction B, the body 231 also includes a second side 231d opposite to the first side 231c. The first cover 22 is generally frame-shaped and includes a first frame 221, a second frame 222, and two first connecting portions 223. The first frame 221 and the second frame 222 are arranged parallel and spaced apart, and the two first connecting portions 223 are respectively connected to the two ends of the first frame 221 and the second frame 222. The first side 231c of the body 231 is connected to the side of the first frame 221 facing the second frame 222, and the second side 231d is connected to the side of the second frame 222 facing the first frame 221. Thus, the first cover 22 prevents air from flowing along the vertical flow direction B.

[0036] In this embodiment, the angle α between the baffle 232 and the body 231 is 60~120 degrees. That is, the angle between the baffle 232 and the airflow direction B is 60~120 degrees. When the angle is within this range, it can effectively block water, ice, dust and other target objects in the air while minimizing the obstruction to airflow. If the angle is too small, the blocking effect may be poor, and some water, ice, dust and other objects may easily enter the cabinet; while if the angle is too large, it will generate greater resistance to airflow, affect heat dissipation efficiency, and be detrimental to heat exchange inside and outside the cabinet 10.

[0037] Along the vertical flow direction B, the cross-sectional width of the first end 231a is greater than that of the second end 231b, resulting in a smaller cross-sectional width of the flow channel along the flow direction B. This facilitates an increase in the velocity of external cold air entering the cabinet 10. According to fluid mechanics principles, when the cross-sectional area of ​​the channel T decreases, the fluid velocity increases under the same pressure difference. For this waterproof heat dissipation component 20, the faster entry of cold air into the cabinet 10 allows for more rapid removal of heat generated by the heat-generating modules within the cabinet 10, thereby improving the overall heat dissipation efficiency of the cabinet, ensuring stable operation of internal electronic equipment in a suitable temperature environment, reducing equipment failures caused by overheating, and extending equipment lifespan.

[0038] In this embodiment, the main body 231 is provided with a fixing groove 234, one end of which is connected to the bottom of the notch 233. A portion of the mounting plate 21 is inserted into the fixing groove 234, thereby limiting the waterproof guide plate 23. The mounting plate 21 is provided with an assembly groove 211 corresponding to the fixing groove 234. After the portion of the mounting plate 21 is inserted into the fixing groove 234, the assembly groove 211 approximately fits into the fixing groove 234, and the edge of the mounting plate 21 is approximately flush with the bottom of the notch 233. Thus, the mounting plate 21 does not need to penetrate the notch 233, thereby reducing the impact on the discharge channel of the target object.

[0039] In this embodiment, along the vertical flow direction B, the opposite sides of the baffle 232 extend beyond the second end 231b to form a limiting block 235, that is, the limiting block 235 protrudes from the first side 231c and the second side 231d. The limiting block 235 is used to further limit the waterproof flow guide plate 23. The first frame 221 and the second frame 222 are each provided with multiple grooves 224 along the extension direction A, and each limiting block 235 can be inserted into one groove 224. In this way, on the one hand, the waterproof flow guide plate 23 can be more securely fixed, preventing displacement of the waterproof flow guide plate 23 due to vibration or other external forces during airflow, ensuring the structural stability of the channel T, maintaining stable heat exchange and target object blocking functions; on the other hand, the cooperation between the limiting block 235 and the groove 224 allows for convenient installation and removal of the waterproof flow guide plate 23, making maintenance of the waterproof heat dissipation assembly 20 or replacement of the waterproof flow guide plate 23 more convenient and improving maintenance efficiency.

[0040] Please see Figure 4 and Figure 5In this embodiment, the waterproof heat dissipation assembly 20 further includes a first housing 24 and a first frame 25. The first housing 24 is connected to the first frame 25 to enclose a first installation space 26. A first cover 22 is disposed within the first installation space 26. The first housing 24 is generally U-shaped and includes two side strips 241, a shell plate 242, and two connecting strips 243. The two side strips 241 are spaced apart, and the shell plate 242 is disposed between the two side strips 241. The shell plate 242 is spaced apart from each side strip 241 to form two ventilation openings 244. The ventilation openings 244 communicate with the channel T. The shell plate 242 covers the notches 233 of multiple waterproof guide plates 23 to enclose a discharge groove 245, which can be used to discharge target objects. The two connecting strips 243 are respectively connected to the two side strips 241 and the two ends of the shell plate 242. The two edge strips 241 extend vertically away from the shell plate 242, forming edge joint strips 241a, and the two edge joint strips 241a are respectively arranged opposite each other. One of the connecting edges is connected to the cabinet 10 by a hinge, so that the waterproof heat dissipation component 20 can be opened and closed at the window 101.

[0041] In this embodiment, the first frame 25 includes two spaced-apart first support plates 251. The first support plates 251 are stepped and include a first step portion 251a and a second step portion 251b. Two side strips 241 are respectively connected to the two first step portions 251a to form a first installation space 26.

[0042] Please see Figure 2 and Figure 5 In this embodiment, the waterproof heat dissipation assembly 20 further includes a fluid drive component 27 for driving air into or out of the cabinet 10. The fluid drive component 27 is connected to the first housing 25 and drives air to flow in the flow direction B or in the opposite direction of the flow direction B. For example, the fluid drive component 27 of one waterproof heat dissipation assembly 20 is used to drive cold air from the outside environment into the cabinet 10 in the flow direction B, and the fluid drive component 27 of another waterproof heat dissipation assembly 20 is used to drive hot air inside the cabinet 10 out of the cabinet 10 in the opposite direction of the flow direction B. The fluid drive component 27 includes an axial fan.

[0043] Please see Figure 4 and Figure 5In this embodiment, the waterproof heat dissipation assembly 20 further includes a second cover 28 and a second housing 29. The second housing 29 is connected to the second cover 28 to enclose and form a second mounting space 30. A fluid drive 27 is disposed in the second mounting space 30. The second mounting space 30 communicates with the first mounting space 26. Specifically, the second cover 28 is generally the same shape as the first cover 22, and the second cover 28 includes a third side frame 281, a fourth side frame 282, and a second connecting portion (not shown). The third side frame 281 and the fourth side frame 282 are arranged parallel and spaced apart, and the second connecting portion is connected to the ends of the third side frame 281 and the fourth side frame 282. The second housing 29 is generally plate-shaped, and the second housing 29 is provided with a plurality of through holes 291 to communicate with the second mounting space 30. The fluid drive 27 is disposed corresponding to the through holes 291.

[0044] The third frame 281 and the fourth frame 282 are arranged at an angle to each other, so that the cross-section of the second cover 28 along the flow direction B is approximately funnel-shaped, and the width of this cross-section decreases along the flow direction B. This helps to further prevent the target object from entering the fluid drive component 27 through the through hole 291. When air carries a small amount of target object that is not completely blocked by the preceding structure towards the fluid drive component 27, this funnel-shaped design can gradually disperse the target object to both sides during airflow, reducing the possibility of the target object entering the through hole 291 and contacting the fluid drive component 27, reducing the risk of damage to the fluid drive component 27 due to target object accumulation, and ensuring the normal operation and service life of the fluid drive component 27.

[0045] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In this embodiment, the waterproof heat dissipation assembly 20 further includes a second housing 31, which is connected between the first housing 25 and the second housing 29. Specifically, the second housing 31 includes a second support plate 311, one side of which is connected to the second housing 29, and the other side is connected to the second stepped portion 251b of the first support plate 251 via a hinge.

[0046] Please see Figure 4 and Figure 5In this embodiment, the waterproof heat dissipation assembly 20 further includes a filter element 32, which is disposed in the second step portion 251b and located between the fluid drive component 27 and multiple waterproof guide vanes 23. The filter element 32 is used to further filter out any small particles, dust, and other impurities that may remain in the air, preventing these impurities from entering the fluid drive component 27 and causing wear or damage to the blades and motor of the fluid drive component 27. The filter element 32 is a metal filter, particularly a stainless steel filter. Stainless steel is chosen because it has good corrosion resistance and strength, and will not rust due to moisture during long-term outdoor use, thus maintaining good filtration performance. Furthermore, the mesh structure of stainless steel is relatively stable and not easily deformed, allowing it to maintain good filtration performance over a long period. Using a stainless steel filter avoids the use of general foamed filter media or non-woven fabric filter media, which have water absorption properties that could affect the filtration function of the heat dissipation airflow. Foamed filter media or non-woven fabric filter screens easily absorb water in humid environments. This water absorption increases airflow resistance, reduces heat dissipation efficiency, and can also breed bacteria or mold, damaging the environment and equipment inside the cabinet 10. Stainless steel filter screens, on the other hand, do not have these problems. They ensure filtration effectiveness while reducing space requirements and increasing the distance between the fluid drive components 27, thus reducing noise generation.

[0047] The waterproof heat dissipation cabinet 100 provided in this application achieves size optimization through the rational layout of the waterproof heat dissipation components 20. For example, the first shell 24, the first frame 25, and other structures in the waterproof heat dissipation components 20 cooperate with each other. The two spaced and stepped first support plates 251 of the first frame 25 are connected to the side strips 241 of the first shell 24 to form an installation space. This compact design ensures that each waterproof heat dissipation component 20 achieves its function without adding excessive space. Moreover, the connection method between the waterproof heat dissipation components 20 and the cabinet 10, such as connecting the side strips 241a with hinges, allows the waterproof heat dissipation components 20 to fit snugly against the cabinet 10 when not in use, without protruding outwards and increasing the overall size of the cabinet 10.

[0048] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
