Description

Technical Field

[0001] This invention relates to the field of power distribution technology, specifically to a high-efficiency heat dissipation switchgear. Background Technology

[0002] In the field of power system distribution equipment, switchgear, as the core equipment for controlling, protecting, and distributing power, directly affects the safety and reliability of the power system due to its operational stability. Especially for outdoor-installed switchgear, which is exposed to the natural environment for extended periods, it must simultaneously address two major challenges: insufficient heat dissipation efficiency and the corrosive effects of humid environments. Existing technologies present numerous problems that urgently need to be solved.

[0003] In terms of heat dissipation, traditional outdoor switchgear has significant limitations. Most switchgear relies on natural heat dissipation through a single ventilation opening or forced cooling by adding fans. Natural heat dissipation is greatly affected by ambient temperature, and in hot weather, it is difficult to quickly dissipate heat from electrical components inside the cabinet, such as transformers and busbars, which can easily lead to localized overheating and accelerate insulation aging. Although forced cooling can improve heat dissipation efficiency, the long-term operation of fans consumes a lot of energy and is prone to failure due to outdoor dust and rainwater intrusion, increasing maintenance costs. Some switchgear attempts to use heat sinks to enhance heat dissipation, but the fins are mostly fixed structures with low heat exchange efficiency with the surrounding environment, failing to form a systematic heat dissipation coordination mechanism and unable to meet the heat dissipation needs of high-power-density outdoor equipment. In addition, existing heat dissipation structures do not effectively utilize natural resources, resulting in a single heat dissipation method and low energy efficiency.

[0004] In terms of moisture protection and environmental adaptability, outdoor switchgear faces the risk of high humidity air intrusion during rainy days, and traditional moisture-proof measures have obvious shortcomings. Existing switchgear dehumidification devices are mostly fixed-installed moisture-absorbing modules or independently operating dehumidifiers: fixed moisture-absorbing modules cannot adjust the moisture-absorbing area according to humidity changes, and in light rain, excessive obstruction of ventilation openings can affect heat dissipation; in heavy rain, they cannot meet the high-intensity moisture absorption requirements. While dehumidifiers can dynamically dehumidify, they require additional power, resulting in high energy consumption, and their reliability is easily affected by rain and dust in complex outdoor environments. Meanwhile, traditional humidity detection relies on a single humidity sensor, which is easily affected by ambient temperature and dust interference, leading to delayed or false alarms in moisture protection triggering.

[0005] Therefore, this invention proposes a high-efficiency heat dissipation switch cabinet to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a high-efficiency heat dissipation switch cabinet to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat dissipation switch cabinet, comprising: a main body and a first component mounted thereon, the first component comprising: a positioning housing for assisting the installation of subsequent components, the positioning housing having a through groove in the middle, and side cavities at the four corners of the inner cavity of the positioning housing, a honeycomb plate A slidably connected inside the positioning housing, auxiliary plates fixedly connected at the four corners of the honeycomb plate A, and auxiliary springs fixedly connected to the auxiliary plates, the auxiliary plates and auxiliary springs being disposed in the side cavities, and the end of the auxiliary springs away from the honeycomb plate A being fixedly connected to the positioning housing; The first component also includes: a honeycomb plate B that is slidably inserted into the positioning housing, wherein the lower surface of the honeycomb plate B is in contact with the upper surface of the honeycomb plate A; The second component is used to adjust dehumidification requirements based on rainfall.

[0008] Preferably, the total height of the honeycomb panel A and the honeycomb panel B is equal to the height of the positioning shell, and the honeycomb panel B has the same shape as the honeycomb panel A and is composed of multiple hollow honeycomb cells.

[0009] Preferably, the first component further includes: a water collection cavity fixedly connected to the upper surface of the honeycomb panel B, wherein filter holes are provided around the water collection cavity and the filter holes are connected to the inner cavity of the water collection cavity, and a weight sensor is fixedly connected to the bottom of the inner cavity of the water collection cavity.

[0010] Preferably, a cabinet door is provided on one side of the main body, multiple sets of electrical components are provided inside the main body, and a back panel is fixedly connected to the side of the main body away from the cabinet door, with ventilation holes provided on the back panel for heat dissipation.

[0011] Preferably, the water collection cavity is provided inside the water collection chamber, and the water collection cavity is surrounded by an outwardly diffusing inclined surface. The weight sensor is electrically connected to an external controller.

[0012] Preferably, the second component includes: a fixed frame fixedly connected to the back plate, the fixed frame having a through groove in the middle, guide rails fixedly connected to both sides of the fixed frame away from the back plate, and arc-shaped guide bodies fixedly connected to both sides of the top of the guide rails.

[0013] Preferably, the guide rail consists of two parallel metal steel channels, the guide rail is perpendicular to the fixed frame, and the symmetrical arc surface of the arc-shaped guide body is made of plastic material.

[0014] Preferably, a cover is fixedly connected to the upper end of the fixed frame, and a device cavity is opened at both ends of the cover. A drive motor is installed in the device cavity, and a roller is fixedly connected to the output shaft of the drive motor. A dehumidifying curtain is installed on the outer ring of the roller. One end of the dehumidifying curtain is fixedly connected to the inside of the roller and is spirally installed on the outer ring of the roller. The end of the dehumidifying curtain away from the roller extends vertically downward. A bottom beam is fixedly connected to both sides of the end of the dehumidifying curtain away from the roller. The bottom beam is slidably connected to the guide rail. A snap-fit ​​strip is fixedly connected to both sides of the dehumidifying curtain.

[0015] Preferably, the spool is a hollow metal spool, and torsion springs are installed at both ends of the spool.

[0016] Compared with the prior art, the present invention provides a high-efficiency heat dissipation switch cabinet, which has the following beneficial effects: 1. By using the inclined surface of the water collection chamber in conjunction with the filter holes to filter and collect rainwater, impurities in the rainwater are intercepted. With the help of a weight sensor, the rainfall amount is fed back, and changes in the amount of rainwater are detected. When the weight of the rainwater reaches a preset threshold, the signal is transmitted to the controller in real time to determine the outdoor humidity status. By combining the rainwater weight with the feedback, compared with the transmission body relying on a single humidity sensor which is easily affected by environmental interference and has a lag, the triggering of this setting is more reliable. It provides accurate environmental parameters for subsequent moisture-proof and heat dissipation adjustment, and improves the switch cabinet's response sensitivity to complex outdoor weather.

[0017] 2. By setting up a water collection cavity, rainwater is collected, which not only triggers moisture protection, but also, during rainless periods, the rainwater stored in the water collection cavity can cooperate with the heat dissipation fins and honeycomb panel A in the main body to form a heat exchange circuit. After the heat inside the main body rises, it comes into contact with the heat dissipation fins. The honeycomb panel A and honeycomb panel B on the top of the main body use the high thermal conductivity of the honeycomb structure to transfer the heat absorbed by the fins to the rainwater. The heat is then carried away by the natural evaporation of the rainwater. By utilizing the specific heat capacity of rainwater, the heat dissipation capacity is enhanced when there is no rain without consuming additional energy.

[0018] 3. By using a weight sensor to receive rainfall data, the height of the dehumidifying curtains is precisely controlled. When rainfall is heavy and outdoor humidity is high, the dehumidifying curtains lower and unfold, increasing the contact area with the air through their moisture-absorbing layer to maximize moisture absorption and block the intrusion path of humid air. This efficiently absorbs moisture passing through the ventilation openings on the back panel, reducing the risk of moisture buildup inside the main unit. When rainfall decreases and outdoor humidity drops, the dehumidifying curtains partially retract, avoiding obstruction of the ventilation openings on the back panel and ensuring unobstructed ventilation. This balance between moisture prevention and heat dissipation prevents damage to the main electrical components from rainy weather and avoids heat dissipation failure caused by long-term obstruction of the dehumidifying structure, thus improving the safety and economy of the equipment operation.

[0019] 4. By combining honeycomb panels A and B with the water collection cavity, a multi-layered three-dimensional heat dissipation system is constructed. The heat generated by the electrical components inside the main body is first transferred to honeycomb panels A and B through the heat dissipation fins. Utilizing the large surface area of ​​the honeycomb structure, the heat is evenly diffused. Some of the heat is further transferred to the rainwater in the water collection cavity through honeycomb panel B, forming a multi-level conduction path from electrical components to heat dissipation fins to the honeycomb panel A and B combination components to rainwater. At the same time, the high thermal conductivity of the heat dissipation fins, the heat dissipation advantages of honeycomb panels A and B, and the heat absorption and evaporation characteristics of rainwater complement each other, jointly bearing heat and significantly improving the overall heat dissipation efficiency. This avoids problems such as insulation aging and component performance degradation caused by local high temperatures. In addition, the design of multiple components jointly bearing heat reduces the heat dissipation pressure of a single structure, improves the stability and durability of the heat dissipation system, and is suitable for the high power density operation requirements of outdoor main bodies.

A back panel 13 is fixedly connected to the side of the main body 11 away from the cabinet door 12. A ventilation opening is provided on the back panel 13 for heat dissipation.

[0027] The water collection cavity 27 has a water collection cavity inside, and the water collection cavity 27 is surrounded by an outwardly diffusing inclined surface. The weight sensor 29 is electrically connected to an external controller.

[0028] A further embodiment: Please refer to Figures 6 to 10 As shown: The second component is used to adjust dehumidification requirements based on rainfall.

[0029] The second component includes: a fixed frame 31 fixedly connected to the back plate 13, a through groove in the middle of the fixed frame 31, guide rails 32 fixedly connected to both sides of the fixed frame 31 away from the back plate 13, and arc-shaped guide bodies 33 fixedly connected to both sides of the top of the guide rails 32. The guide rails 32 and the arc-shaped guide bodies 33 cooperate to limit the movement trajectory of the scroll 37 and ensure the vertical stability of the scroll 37 during lifting and lowering, avoid deviation or shaking, and enhance the overall rigidity.

[0030] The guide rail 32 consists of two parallel metal steel channels. The guide rail 32 is set perpendicularly to the fixed frame 31. The symmetrical arc surface of the arc-shaped guide body 33 is made of plastic.

[0031] A cover 34 is fixedly connected to the upper end of the fixed frame 31. The cover 34 is used to protect components such as the roller 37 from dust and other outdoor environmental influences. Both ends of the cover 34 have device cavities 35, each containing a drive motor 36. The output shaft of the drive motor 36 is fixedly connected to the roller 37, which is used to wind the carrier. Rotation of the roller 37 drives the dehumidifying curtain 38 to rise and fall, adjusting the area for adsorbing external moisture. The outer ring of the roller 37 is equipped with the dehumidifying curtain 38. One end of the dehumidifying slat 38 is fixedly connected to the inside of the roller 37 and is spirally installed on the outer ring of the roller 37.

The bottom beam 310 is used to increase the weight at the bottom of the roller 37, making it more stable when it descends.

[0032] The spool 37 is a hollow metal spool, and torsion springs are installed at both ends of the spool 37.

[0033] Among them, the dehumidifying curtain 38 is composed of a stainless steel perforated plate and a moisture-absorbing layer filled with composite silica gel desiccant in the gaps between the holes.

[0034] Heat dissipation fins are provided on the top of the main body 11.

[0035] The working principle of all the content in the above embodiments is as follows: The following is the working process of the first component: During use, the heat generated by the internal electrical components of the main body 11 during normal operation is dissipated outward through the ventilation openings of the upper back plate 13. The positioning housing 21 serves as the basic mounting component, providing support for subsequent heat dissipation. At this time, the honeycomb panel A23 is in its initial sliding position within the positioning housing 21, and its four corner auxiliary plates 24 are stably connected to the positioning housing 21 via auxiliary springs 25. The honeycomb panel B26 is aligned with the central through slot of the positioning housing 21 for installation. The lower surface of the honeycomb panel B26 is in contact with the upper surface of the honeycomb panel A23. The weight of the honeycomb panel B26 and the water collection cavity 27 is supported by the... Under the action of force, the honeycomb panel A23 and the auxiliary plate 24 are pressed down towards the main body 11. At this time, the auxiliary spring 25 is stretched to store potential energy and provides a buffer for the installation of components such as the honeycomb panel B26 under the characteristics of the auxiliary spring 25. When the hot air inside the main body 11 is cooled, the honeycomb panel A23 and the honeycomb panel B26 are installed and fit together. Under the action of the hot air rising, the high air permeability and large surface area of ​​the honeycomb panel A23 and the honeycomb panel B26 are used to accelerate the convection exchange between the hot air inside the main body 11 and the cold air outside, and enhance the air heat dissipation efficiency. Furthermore, during rainy weather, the water collection cavity 27 collects rainwater through its outwardly sloping surface and filters impurities in the rainwater through the filter holes 28. The rainwater then flows through the filter holes 28 into the water collection cavity of the water collection cavity 27 and converges. At this time, the water collection cavity 27 not only prevents rainwater from directly intruding into the main body 11 through its shell structure, but also utilizes the rainwater collected in the water collection cavity 27 in conjunction with the honeycomb panels B26 and A23 to exchange heat with the heat dissipation fins inside the main body 11. After the rainwater absorbs the heat transferred from the main body 11 by the water collection cavity 27, its temperature rises. Some of the rainwater carries away the heat through natural evaporation, while the other part indirectly enhances the heat dissipation efficiency through the heat conduction channels of the honeycomb panels A23 and B26, further reducing the temperature inside the main body 11 and achieving the synergistic effect of rainwater-assisted heat dissipation. By using the inclined surface of the water collection cavity 27 in conjunction with the filter hole 28, rainwater is filtered and collected, intercepting impurities in the rainwater. With the help of the weight sensor 29, the rainfall is fed back, sensing changes in the amount of rainwater. When the weight of the rainwater reaches a preset threshold, the signal is transmitted to the controller in real time to determine the outdoor humidity status. By combining the rainwater weight with the feedback, compared with the transmission body 11 relying on a single humidity sensor which is easily affected by environmental interference and has a lag, the triggering of this setting is more reliable. It provides accurate environmental parameters for subsequent moisture-proof and heat dissipation adjustments, and improves the switch cabinet's response sensitivity to complex outdoor weather.

[0036] By setting up the water collection cavity 27, rainwater is collected, which not only triggers moisture protection, but also allows the rainwater stored in the water collection cavity 27 to cooperate with the heat dissipation fins and honeycomb panel A23 in the main body 11 to form a heat exchange circuit during rainless periods. After the heat inside the main body 11 rises, it comes into contact with the heat dissipation fins. The honeycomb panel A23 and honeycomb panel B26 above the main body 11 use the high thermal conductivity of the honeycomb structure to transfer the heat absorbed by the fins to the rainwater. The heat is then carried away by the natural evaporation of the rainwater. By utilizing the specific heat capacity of rainwater, the heat dissipation capacity is enhanced during rainless periods without consuming additional energy.

[0037] Please refer to the above work process. Figures 1 to 5 .

[0038] The following is the working process of the second component: During use, as the rainfall increases, the amount of rainwater collected in the water collection chamber 27 gradually increases. When the weight of the rainwater reaches a preset threshold, the weight sensor 29 installed in the water collection chamber 27 is triggered, transmitting the rainfall signal to the external controller. The controller adjusts the settings of the second component based on the feedback signal. Furthermore, the weight sensor 29 works in conjunction with the controller, and the signal transmission causes the controller to start the drive motor 36. The output shaft of the drive motor 36 drives the roller 37 to rotate in the forward direction. Since the roller 37 is equipped with torsion springs at both ends and rotates synchronously with the roller 37, the torsion springs store elastic potential energy as the roller 37 rotates, providing power for subsequent reset. When the roller 37 rotates in the forward direction, the roller 37 wound around its outer ring gradually unfolds as the roller 37 rotates. The end of the dehumidifying curtain 38 away from the roller 37 slides along the guide rail 32 through the bottom beams 310 on both sides. The snap-fit ​​strip 39 slides against the arc-shaped guide body 33 and cooperates with the guide rail 32 to reduce the frictional resistance between the dehumidifying curtain 38 and the guide rail 32, ensuring the stability of the lifting process. The bottom beams 310 also increase the weight at the bottom of the dehumidifying curtain 38 to avoid deviation caused by airflow and other errors, and assist the vertical lifting of the dehumidifying curtain 38. When the rainfall is too heavy, the roller 37 continues to rotate in the forward direction, and the dehumidifying curtain 38 descends and unfolds along the guide rail 32, increasing the contact area with the outside air. Through the moisture-absorbing layer of the dehumidifying curtain 38, moisture in the air is absorbed, reducing the amount of high-humidity air entering the main body 11 through the back plate 13, thus preventing electrical components from being damaged by moisture. When the rainfall decreases, the drive motor 36 rotates in the reverse direction, and the roller 37 assists in rotating in the reverse direction under the release of the torsion spring, saving energy. The dehumidifying curtain 38 rises and retracts, gradually winding around the outer ring of the roller 37, reducing the obstruction of the ventilation openings set at the back plate 13 and restoring an efficient heat dissipation channel. If it does not rain, the rainwater collected in the water collection chamber 27 can still assist the subsequent heat exchange and dissipation in the main body 11 by cooperating with multiple components. After the rainwater evaporates, the weight sensor 29 transmits a signal value to the main controller, and the reel 37 is wound back to its original position, thus forming a reciprocating motion. By using the weight sensor 29 to receive rainfall signals, the raising and lowering of the dehumidifying curtain 38 is precisely controlled. When rainfall is excessive and outdoor humidity is high, the dehumidifying curtain 38 lowers and unfolds, increasing its contact area with the air through its moisture-absorbing layer to maximize moisture absorption, block the intrusion path of humid air, and efficiently absorb moisture through the ventilation openings set at the back panel 13, reducing the risk of moisture inside the main body 11 from the source. When rainfall decreases and outdoor humidity decreases, the dehumidifying curtain 38 partially retracts to avoid obstructing the ventilation openings at the back panel 13, ensuring unobstructed ventilation channels. This establishes a balance between moisture prevention and heat dissipation, preventing rainy weather moisture from damaging the electrical components of the main body 11 and avoiding heat dissipation failure caused by long-term obstruction of the dehumidifying structure, thus improving the safety and economy of equipment operation.

[0039] By combining honeycomb panels A23 and B26 with the water collection cavity 27, a multi-layered three-dimensional heat dissipation system is constructed. The heat generated by the electrical components inside the main body 11 is first transferred to honeycomb panels A23 and B26 through the heat dissipation fins. Utilizing the large surface area of ​​the honeycomb structure, the heat is evenly diffused. Some of the heat is further transferred to the rainwater in the water collection cavity 27 through honeycomb panel B26, forming a multi-level conduction path from electrical components to heat dissipation fins to honeycomb panels A23 and B26 to rainwater. At the same time, the high thermal conductivity of the heat dissipation fins, the heat dissipation advantages of honeycomb panels A23 and B26, and the heat absorption and evaporation characteristics of rainwater complement each other, jointly bearing heat and significantly improving the overall heat dissipation efficiency. This avoids problems such as insulation aging and component performance degradation caused by local high temperatures. In addition, the design of multiple components jointly bearing heat reduces the heat dissipation pressure of a single structure, improves the stability and durability of the heat dissipation system, and is suitable for the high power density operation requirements of the outdoor main body 11.
