Description

Technical Field

[0001] This utility model relates to the field of electrical equipment moisture-proof technology, and in particular to a composite flow guiding structure, a composite water scraping structure, a moisture-proof device, and electrical equipment. Background Technology

[0002] Electrical equipment is typically installed in dedicated electrical cabinets or distribution cabinets. Besides common indoor locations (such as substations or distribution rooms), some distribution cabinets are also installed directly outdoors. Outdoor-installed distribution cabinets require higher performance, including rain and moisture protection. Electrical equipment continuously generates heat and noise during operation; therefore, distribution cabinets and substations must have excellent heat dissipation and noise reduction capabilities. Currently, various devices have been developed to ensure effective heat dissipation and moisture protection. The most widely used type utilizes the principle of water vapor condensing into water droplets upon cooling, condensing and expelling water vapor from inside the device to achieve moisture protection. However, existing dehumidification devices still have the following problems: 1. Condensate droplets on the original structure's guide plate rely solely on gravity to flow down naturally, which easily leads to uneven distribution; 2. The wiper blades rely on the lifting and lowering of the guide plate and gravity for movement, resulting in low automation and a lack of active drive mechanisms, leading to unadjustable wiping frequency and unstable wiping effect; 3. The cooling fins have limited heat dissipation capacity, affecting overall condensation efficiency; 4. The humidity sensor only has humidity monitoring functions and is not deeply integrated with the control system, resulting in low automation of dehumidification operation; 5. Drainage relies solely on a natural tilting structure, which easily leads to poor drainage.

[0003] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as uneven condensate distribution, low automation of the squeegee mechanism and dehumidification operation, limited heat dissipation efficiency, and poor drainage.

[0029] Example 1 This embodiment relates to the composite flow guiding structure of this utility model.

[0030] An illustrative embodiment of this utility model, such as Figure 1 As shown, a composite flow guiding structure 100 for use in electrical equipment includes a flow guiding plate element 101, a plurality of protruding elements 102, a plurality of flow guiding baffle elements 103, and a flow guiding groove element 104. The flow guiding plate element 101 is inclined; the plurality of protruding elements 102 are distributed on the upper part of the flow guiding plate element 101; the plurality of flow guiding baffle elements 103 are distributed on the middle part of the flow guiding plate element 101 and located downstream of the plurality of protruding elements 102; and the flow guiding groove element 104 is disposed on the lower part of the flow guiding plate element 101.

[0031] The deflector element 101 is flat.

[0032] In this invention, the deflector element 101 is divided into a first region, a second region, and a third region. The first region is located at the upper part of the deflector element 101, and its area is 30% of the total area of ​​the deflector element 101. The first region is provided with a plurality of protruding elements 102. The second region is located at the middle part of the deflector element 101, and its area is 40% of the total area of ​​the deflector element 101. The second region is provided with a plurality of deflector baffle elements 103. The third region is located at the lower part of the deflector element 101, and its area is 30% of the total area of ​​the deflector element 101.

[0033] In this invention, the first, second, and third regions of the guide vane element 101 each have different functions. Specifically, in the first region, the surface has strong condensation properties, used to condense water vapor into droplets and guide them to the corresponding area; its ability to collect water droplets is far superior to that of a smooth surface. In the second region, its function is to guide the water flow along the optimal path to ensure efficient drainage and avoid water accumulation when the guide vane element 101 condenses many water droplets to form a water flow. The water flow may be dispersed or flow irregularly due to surface tension or minor resistance. The second region is used to guide the water flow to flow quickly along the optimal path, thus ensuring efficient drainage and avoiding water accumulation. In the third region, the surface is an ultra-smooth surface, occupying 30% of the area of ​​the guide vane element 101. The ultra-smooth surface has almost "frictionless," "non-scattering," and "non-adsorption" characteristics, making the drainage path unobstructed.

[0034] The protruding element 102 is formed on the upper part of the guide plate element 101. Generally, it is manufactured by machining methods (such as integral molding). The above-mentioned machining methods are conventional technical means in this technical field and will not be described in detail here.

[0035] A plurality of protruding elements 102 are arranged in an array on the guide plate element 101. Generally, the plurality of protruding elements 102 form n rows and m columns, where n≥2 and m≥2.

[0036] In some embodiments, the protruding elements 102 in the previous row are arranged intersectingly with the protruding elements 102 in the next row. Specifically, for two adjacent protruding elements 102 in the previous row, a protruding element 102 is provided below the gap between them; for two adjacent protruding elements 102 in the next row, a protruding element 102 is provided above the gap between them.

[0037] In some embodiments, the number of protrusions 102 in odd-numbered rows is equal, the number of protrusions 102 in even-numbered rows is equal, and the number of protrusions 102 in odd-numbered rows is not equal to the number of protrusions 102 in even-numbered rows.

[0038] The height of the protruding element 102 is 0.5-1mm.

[0039] In some of these embodiments, the raised element 102 is a circular curved protrusion, which is used to enhance the ability to condense water droplets.

[0040] The extension direction of the flow guide baffle element 103 is the same as the width direction of the flow guide baffle element 101.

[0041] The flow guide baffle element 103 is formed in the middle of the flow guide baffle element 101.

[0042] Generally, the height of the flow guide baffle element 103 is 0.3-0.5mm.

[0043] Several flow guide baffle elements 103 are spaced apart along the length direction of the flow guide element 101.

[0044] Generally, the flow guide baffle element 103 is located at the interval between two adjacent protruding elements 102.

[0045] The cross-section of the flow guide baffle element 103 is rectangular, trapezoidal, or similar.

[0046] In some of these embodiments, the height of the flow deflector element 103 decreases from the end closer to the protrusion element 102 to the end farther away from the protrusion element 102.

[0047] The flow guide baffle element 103 is used to force the water flow to converge and move along the designed fastest path, so as to maximize the drainage efficiency and prevent the water flow from "going astray" or forming uncontrollable puddles.

[0048] The advantages of this invention lie in its innovative design of the guide plate element, which significantly improves moisture-proof and drainage efficiency through multiple structural optimizations. The densely packed protruding elements on the surface of the guide plate element greatly enhance water vapor condensation efficiency, far exceeding that of a smooth surface. The lower guide baffle element provides a directional path for the water flow through physical constraints, eliminating flow dispersion and ensuring efficient drainage of condensate. Furthermore, ultra-smooth surface treatment is used in key drainage areas to achieve near-frictionless and non-adhesive rapid drainage. Combined with composite curved surface path optimization, this completely avoids the risk of localized water accumulation.

[0058] The substrate element 203 is arranged parallel to the flow guide plate element 101.

[0059] Generally, the length of the substrate element 203 is approximately equal to the width of the guide plate element 101, and the width of the substrate element 203 is less than the length of the guide plate element 101.

[0060] In some of these embodiments, the substrate element 203 includes, but is not limited to, mounting substrate and connecting substrate.

[0061] In some of the embodiments, the substrate element 203 is made of metal and has a wear-resistant coating on its surface.

[0062] The deformable buffer element 204 is fixedly connected to the substrate element 203, and the substrate element 203 provides a certain pressure to the deformable buffer element 204 so that the water droplets on the surface of the composite flow guiding structure 100 can be wiped clean.

[0063] In some of these embodiments, the deformation buffer element 204 is made of a flexible material, preferably a silicone buffer layer.

[0064] In some of these embodiments, the deformable buffer element 204 includes, but is not limited to, a deformable buffer scraper.

[0065] Furthermore, the composite wiper structure 200 also includes a guide element 205, which is disposed on the second side of the guide plate element 101 and slidably connected to the substrate element 203 to assist the movement of the substrate element 203.

[0066] The guide element 205 extends along the length of the guide plate element 101.

[0067] Generally, the length of the guide element 205 is approximately equal to the length of the deflector element 101.

[0068] In some of these embodiments, the guide element 205 includes, but is not limited to, a guide rod.

[0069] The advantages of this utility model are that, based on the excellent flow guidance and drainage technology in Embodiment 1, a composite wiping structure is added, realizing the transformation from passive defense to active management. The wiping frequency can be dynamically adjusted according to real-time environmental humidity data or preset programs, which greatly improves the response capability to sudden high humidity environments and the energy efficiency of daily operation. At the same time, the composite wiping structure adopts flexible materials and is designed with the composite flow guidance structure to ensure good contact between the deformation buffer element and the surface of the flow guide element. It can deform under micro-pressure, embed into the gap to achieve better wiping, and also has good wear resistance, which further ensures the performance stability under long-term high-frequency reciprocating motion.

[0098] In this invention, the liquid cooling element 502 is connected to the coil element 501.

[0099] Specifically, the outlet of the liquid cooling element 502 is connected to the inlet of the coil element 501 via a pipe, and the outlet of the coil element 501 is connected to the inlet of the liquid cooling element 502 via a pipe.

[0100] Furthermore, the heat dissipation structure 500 can preferably be configured as a heat pipe heat dissipation system, including a heat-conducting base, heat pipes, and heat dissipation fins: the base is attached to the heating end of the cooling structure 300 to absorb heat; after the heat pipe (evaporation end) containing working fluid is heated, the working fluid quickly vaporizes and flows to the other end (condensation end), where it releases heat and then re-condenses into a liquid, flowing back to the evaporation end through the capillary structure inside the pipe, forming an efficient automatic circulation; finally, the heat is dissipated into the air through a large number of heat dissipation fins, thereby achieving a fast, uniform, and quiet heat dissipation effect.

[0101] Furthermore, the heat dissipation structure 500 also includes a first fan, a second fan, and a cooling fan. The first fan is located at the cooling end of the cooling structure 300 and drives the air inside the moisture-proof device A through the composite flow guide structure 100 to achieve condensation dehumidification and remove internal heat. The second fan is located at the heating end of the cooling structure 300 and dissipates heat from the heating end of the cooling structure 300. The cooling fan is located at the heating end of the cooling structure 300 and dissipates internal heat from the moisture-proof device A.

[0102] The first fan can drive the air circulation inside the moisture-proof device A.

[0103] The second fan and cooling fan can dissipate heat from the heating end of the cooling structure 300. The cooling fan is a three-stage variable frequency cooling fan. Compared with ordinary fans, the three-stage variable frequency cooling fan has three preset, distinct speed modes (low speed / silent mode, medium speed / balanced mode, and high speed / performance mode), and can automatically switch between these three modes as needed.

[0104] Furthermore, the moisture-proof device A also includes at least one drainage structure 600. The drainage structure 600 is disposed in the flow channel element 104 of the composite flow guiding structure 100 and is used for drainage.

[0105] In this invention, the number of drainage structures 600 is equal to the number of composite flow guiding structures 100.

[0106] Furthermore, the drainage structure 600 includes a drainage auxiliary device and a drainage channel. The drainage auxiliary device is located inside the flow channel element 104 of the composite flow guiding structure 100; the drainage channel is located on the side of the moisture-proof device A and is connected to the flow channel element 104 in the composite flow guiding structure 100 for discharging water.

[0107] In some embodiments, the drainage aid includes, but is not limited to, a miniature water pump. It provides power to overcome gravity limitations, increases the drainage rate, and prevents water from flowing slowly due to excessively long drainage channels, insufficient slope, or sediment, thus preventing stagnation and water accumulation within the channels and additional moisture damage to electrical equipment.

[0108] Furthermore, the moisture-proof device A also includes an air vent structure. This air vent structure includes a primary air vent element, a secondary air vent element, a first air vent baffle element, a second air vent baffle element, and a third driving element. The primary air vent element is used for airflow and heat dissipation in the upper section of the composite airflow guiding structure 100; the secondary air vent element is used for airflow and heat dissipation in the lower section of the composite airflow guiding structure 100; the first air vent baffle element is used to block the primary air vent element; the second air vent baffle element is used to block the secondary air vent element; and the third driving element is connected to the first and second air vent baffle elements respectively, providing power to the first and second air vent baffle elements to block the primary and secondary air vent elements.

[0109] In this utility model, the air vent structure is a conventional technical means in this technical field, and will not be described in detail here.

[0110] The method of using this utility model is as follows: In the initial state, the electrical equipment is placed on the hollow shelf, the air guide plate element 101 is tilted at 25°, the air window is open, the device is in standby state, the humidity sensor monitors in real time, the sampling interval is 10 seconds / time, and when the relative humidity value is >65% for 5 minutes, the dehumidification action is triggered. When dehumidification is started, the air vent structure is closed, and the baffle element 101 is tilted to 40° via the angle adjustment structure 400. The heat dissipation structure 500, the refrigeration structure 300, and other related refrigeration and heat dissipation structures are all started, gradually increasing to full power. While the first fan assists in the heat dissipation of the electrical equipment, it also causes water vapor inside the cabinet to condense into water droplets on the baffle element 101. The composite scraping structure 200 in Example 2 circulates once every 30 seconds, and the drainage structure 600 works intermittently to facilitate the smooth discharge of water droplets. The system adjusts the cooling power in real time. When dehumidification is complete, if the relative humidity remains below 55% for 10 minutes, all structures will gradually shut down, restoring the initial state.

[0111] The advantages of this invention are that by optimizing the composite flow guiding structure of Embodiment 1, the dehumidification efficiency is significantly improved; at the same time, the refrigeration system effectively enhances the heat dissipation performance, ensuring the stable operation of the semiconductor cooling chip in a high-temperature environment; the optimized drainage system ensures that condensate droplets are quickly discharged. Through the above-mentioned automated dehumidification and heat dissipation design, this invention greatly improves the internal environment of the electrical cabinet and significantly enhances the safety and reliability of equipment operation.

[0114] In addition, the electrical equipment may also include at least one composite wiper structure 200 as in Embodiment 2.

[0115] Furthermore, the electrical equipment may also include a moisture-proof device A, as in Example 3.

[0116] The usage method and technical effects of this embodiment are basically the same as those of Embodiments 1 to 3, and will not be repeated here.

[0117] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
