Description

Technical Field

[0001] This utility model belongs to the field of ventilation and heat dissipation of electrical cabinets, specifically relating to a louver device and an electrical cabinet. Background Technology

[0002] Electrical cabinets are characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, and wide application. They are the control center for the rational distribution of electrical energy among various components in the power supply line, the control link for reliably receiving the upstream power supply and correctly outputting the load electrical energy, and the key to obtaining user satisfaction with the power supply quality.

[0003] To ensure good heat dissipation in electrical cabinets, most electrical cabinets use louvers for ventilation. However, the existing louver structure of electrical cabinets is simple. When it is windy or rainy, splashing solid particles and rainwater can pass through the louvers and enter the electrical cabinet, affecting the insulation of the electrical components inside the cabinet, reducing power supply reliability, and failing to effectively guarantee the safety of operators and equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Reference Figures 1 to 9 This utility model provides a louver device, including a first louver 10 and a second louver 20.

[0048] The first venetian blind 10 includes a first venetian blind frame 102 and a plurality of first blades 101, the plurality of first blades 101 being arranged parallel to each other and spaced apart along a first direction and fixedly connected to the first venetian blind frame 102; the second venetian blind 20 includes a second venetian blind frame 202 and a plurality of second blades 201, the plurality of second blades 201 being arranged parallel to each other and spaced apart along a second direction and fixedly connected to the second venetian blind frame 202; the first venetian blind 10 and the second venetian blind 20 are stacked, the first blades 101 being located in the gap between two adjacent second blades 201, and the second blades 201 being located in the gap between two adjacent first blades 101.

[0049] like Figures 1 to 9 As shown, the louver device includes a first louver 10 and a second louver 20. The first blade 101 of the first louver 10 is arranged in the gap between adjacent second blades 201 of the second louver 20, and the second blades 201 of the second louver 20 are arranged in the gap between adjacent first blades 101 of the first louver 10. This staggered arrangement of the first blades 101 and the second blades 201 allows for layered rain protection during wind and rain, thereby improving the waterproof performance of the louver device.

[0050] In the embodiments of this utility model, a plurality of first blades 101 are arranged parallel to each other and spaced apart along a first direction, and second blades 201 are arranged parallel to each other and spaced apart along a second direction, as shown below. Figure 2 As shown, the first venetian blind frame 102 includes a horizontal frame and a vertical frame. During installation, its horizontal frame direction is parallel to the ground, and its vertical frame direction is perpendicular to the ground. The first direction can be either the horizontal frame direction of the first venetian blind frame 102 (Y-axis direction) or the vertical frame direction of the first venetian blind frame 102 (Z-axis direction). Since the first slats 101 are parallel to each other, when the first slats 101 are spaced apart along the Y-axis, the first slats 101 are perpendicular to the Z-axis; when the first slats 101 are spaced apart along the Z-axis, the first slats 101 are perpendicular to the Y-axis. Figure 3As shown, the second louver frame 1202 includes a horizontal frame and a vertical frame. During installation, its horizontal frame is parallel to the ground, and its vertical frame is perpendicular to the ground. The second direction can be either the horizontal frame direction (Y-axis) or the vertical frame direction (Z-axis). Since the second blades 201 are parallel to each other, when the second blades 201 are spaced apart along the Y-axis, they are perpendicular to the Z-axis; when they are spaced apart along the Z-axis, they are perpendicular to the Y-axis. Furthermore, there are gaps between adjacent first blades 101 and adjacent second blades 201. The size of these gaps can be the same or different. When the gaps between adjacent first blades 101 and adjacent second blades 201 are the same, the first louver 10 and the second louver 20 will overlap more tightly, resulting in better waterproofing.

[0051] Furthermore, in the embodiments of this utility model, all the first blades 101 and the second blades 201 can be made by cold rolling, which makes the first blades 101 and the second blades 201 highly machinable, simple to process and low in cost, suitable for large-scale mass production and application in industrial products, thereby improving the practical applicability of the device.

[0052] Optionally, refer to Figure 5 The first blade 101 includes a first plate 1011, a second plate 1012, and a third plate 1013. Along the direction in which the first blade 101 is arranged, the second plate 1012 is fixedly connected to the first plate 1011 and the third plate 1013 respectively, and the included angles between the second plate 1012 and the first plate 1011 and the third plate 1013 are all obtuse angles; and / or, the second blade 201 includes a fourth plate 2011, a fifth plate 2012, and a sixth plate 2013. Along the direction in which the second blade 201 is arranged, the fifth plate 2012 is fixedly connected to the fourth plate 2011 and the sixth plate 2013 respectively, and the included angles between the fifth plate 2012 and the fourth plate 2011 and the sixth plate 2013 are all obtuse angles;

[0053] The first plate 1011, the second plate 1012, and the third plate 1013 are distributed sequentially along the first direction;

[0054] The fourth plate 2011, the fifth plate 2012 and the sixth plate 2013 are distributed sequentially along the second direction.

[0055] like Figure 5As shown, the first blade 101 includes a first plate 1011, a second plate 1012, and a third plate 1013. The second plate 1012 is fixedly connected to both the first plate 1011 and the third plate 1013. The first plate 1011, the second plate 1012, and the third plate 1013 are sequentially distributed along a first direction. Figure 5 As can be seen, the first direction can be either the Z-axis or the Y-axis. The first blade 101 has a bent structure, which provides a flow channel for airflow through multiple bends, thereby improving the ventilation and heat dissipation effect of the louver device. Since the angles between the second plate 1012 and the first plate 1011 and the third plate 1013 are all obtuse angles, the water-blocking area of ​​the first blade 101 is increased, improving the waterproof performance of the louver device.

[0056] The second blade 201 includes a fourth plate 2011, a fifth plate 2012, and a sixth plate 2013. The fifth plate 2012 is fixedly connected to the fourth plate 2011 and the sixth plate 2013, respectively. The fourth plate 2011, the fifth plate 2012, and the sixth plate 2013 are distributed sequentially along the second direction. Figure 5 As can be seen, the second direction can be either the Z-axis or the Y-axis. The second blade 201 also has a bent structure, which helps the airflow and thus improves the ventilation and heat dissipation effect of the louver device. In addition, the angles between the fifth plate 2012, the fourth plate 2011, and the sixth plate 2013 are all obtuse angles, which increases the water-blocking area of ​​the second blade 201 and also helps to waterproof the louver device.

[0057] In one embodiment of this utility model, when rainwater is blown into the first louver 10 along the positive X-axis, some of the rainwater will be blocked by the first flat plate 1011, and the rest of the rainwater will flow in through the gap between adjacent first blades 101. Some of the flowing rainwater will be blocked by the second flat plate 1012 and the third flat plate 1013, and the remaining rainwater will flow out through the gap at the other end of the adjacent first blades 101, thereby entering the second louver 20 and being blocked by the second louver 20. Finally, the rainwater flows out along the flow channel formed by the first louver 10 and the second louver 20, thereby achieving the function of waterproofing.

[0058] In the embodiments of this utility model, both the first blade 101 and the second blade 201 can be configured as bent structures, or either the first blade 101 or the second blade 201 can be configured as bent structures, both of which can effectively improve the ventilation and heat dissipation performance of the louver device. Of course, configuring both the first blade 101 and the second blade 201 as bent structures will result in even better ventilation and heat dissipation. Regarding the positional relationship between the first plate 1011 and the third plate 1013, they can be arranged in parallel. When the first plate 1011 and the third plate 1013 are parallel, the passage of light can be reduced after the first louver 10 is closed, thereby improving the sealing performance of the first louver 10. Similarly, the fourth plate 2011 and the sixth plate 2013 can also be arranged in parallel, thereby reducing the passage of light and improving the sealing performance of the second louver 20.

[0059] Optionally, along the direction in which the first blades 101 are arranged, there is a first gap H1 between the fourth plate 2011 and the third plate 1013 on the adjacent side;

[0060] And / or, along the direction in which the first blades 101 are arranged, there is a second gap H2 between the fourth plate 2011 and the third plate 1013 on the adjacent other side.

[0061] like Figure 5 As shown, when a first gap H1 exists between the fourth plate 2011 and the adjacent third plate 1013 along the direction of the first blades 101, airflow can enter the electrical cabinet through the louver device, achieving ventilation and heat dissipation. Similarly, when a second gap H2 exists between the fourth plate 2011 and the adjacent third plate 1013 along the direction of the first blades 101, airflow can enter the electrical cabinet through the louver device, achieving ventilation and heat dissipation. The ventilation and heat dissipation effect can be achieved by only having the first gap H1 or only having the second gap H2, or by designing to have both the first gap H1 and the second gap H2, the ventilation and heat dissipation effect will be even better.

[0062] Optionally, refer to Figure 5 The first plate 1011 is parallel to the fourth plate 2011, the second plate 1012 is parallel to the fifth plate 2012, and the third plate 1013 is parallel to the sixth plate 2013.

[0063] like Figure 5As shown, the first plate 1011 is parallel to the fourth plate 2011, the second plate 1012 is parallel to the fifth plate 2012, and the third plate 1013 is parallel to the sixth plate 2013. This design ensures that all components of the first blade 101 and the second blade 201 are parallel, resulting in a tighter fit and more effective prevention of rainwater inflow. Furthermore, the parallelism of the components of the first blade 101 and the second blade 201 facilitates blade manufacturing and reduces processing costs.

[0064] Optionally, refer to Figure 6 The louver device also includes a flow guide 30, which includes a first side plate 302, a second side plate 303, a third side plate 304 and a fourth side plate 305.

[0065] The first side plate 302 and the third side plate 304 are arranged opposite to each other, and the second side plate 303 and the fourth side plate 305 are arranged opposite to each other. The first side plate 302, the second side plate 303, the third side plate 304 and the fourth side plate 305 are connected in sequence to form a cavity 301. The first louver 10 and the second louver 20 are embedded in the cavity 301.

[0066] like Figure 6 As shown, the first louver 10 and the second louver 20 are embedded in the cavity 301. Since the first louver 10 and the second louver 20 are both located inside the cavity 301, when rainwater passes through the first louver 10 and the second louver 20, it will be blocked and flow downwards, thus falling into the cavity 301, preventing rainwater from seeping into the electrical cabinet and improving the safety of the electrical cabinet.

[0067] In the embodiments of this utility model, since the first side plate 302, the second side plate 303, the third side plate 304 and the fourth side plate 305 are connected in sequence to form a cavity 301, when the shapes of the first side plate 302, the second side plate 303, the third side plate 304 and the fourth side plate 305 are all trapezoidal, the cavity 301 is frustum-shaped, and the cavity 301 includes two openings of different sizes. When rainwater rushes in from the end with the larger opening of the cavity 301, it is blocked by the cavity 301 as much as possible, thereby improving the waterproof performance of the entire louver device.

[0068] Optionally, refer to Figure 6 The first side plate 302 and the third side plate 304 are inclined to each other in opposite directions and the inclination angle is acute; and / or the second side plate 303 and the fourth side plate 305 are inclined to each other in opposite directions and the inclination angle is acute.

[0069] like Figure 6As shown, the first side plate 302 and the third side plate 304 are inclined towards each other in opposite directions, with acute angles. It can be seen that the first side plate 302 and the third side plate 304 are arranged along the Z-axis, with the first side plate 302 inclined in the negative Z-axis direction and the third side plate 304 inclined in the positive Z-axis direction. While their inclination directions are opposite, both are acute angles. When it is windy and rainy, rainwater enters the deflector 30 along the positive X-axis direction. At this time, some of the rainwater will be blocked by the inclined first side plate 302 and the third side plate 304. Due to gravity, the rainwater will flow rapidly down the inclined surfaces of the first side plate 302 and the third side plate 304, thus quickly discharging the water.

[0070] from Figure 6 It can also be seen that the second side plate 303 and the fourth side plate 305 are also inclined towards each other, and the inclination directions are opposite, with an acute angle. The second side plate 303 and the fourth side plate 305 are arranged along the Y-axis direction, with the second side plate 303 inclined along the negative Y-axis direction and the fourth side plate 305 inclined along the positive Y-axis direction. The inclination directions of the two are opposite, but the inclination angles are both acute. When it is windy and rainy, rainwater enters the deflector 30 along the positive X-axis direction. At this time, some of the rainwater will be blocked by the inclined second side plate 303 and the fourth side plate 305. Due to the gravity of the water, the rainwater will flow down quickly along the inclined surfaces of the second side plate 303 and the fourth side plate 305, thereby quickly expelling the water.

[0071] In the embodiments of this utility model, the inclination directions of the first side plate 302 and the third side plate 304 can be interchanged, and the inclination directions of the second side plate 303 and the fourth side plate 305 can also be interchanged. However, it is necessary to ensure that the inclination directions of the first side plate 302 and the third side plate 304 are opposite, and the inclination directions of the second side plate 303 and the fourth side plate 305 are opposite. At this time, the cavity 301 formed by the first side plate 302, the second side plate 303, the third side plate 304 and the fourth side plate 305 is frustum-shaped, and the cavity 301 includes two openings of different sizes. When rainwater rushes in from the larger opening end of the cavity 301, it is blocked as much as possible, thereby improving the waterproof performance of the entire louver device.

[0072] Optionally, refer to Figure 7 Along the direction of gravity, the bottom of the first louver 10 is lower than the bottom of the second louver 20, and there is a gap between the bottom of the first louver 10 and the bottom of the cavity 301.

[0073] Or, refer to Figure 8 Along the direction of gravity, the bottom of the second louver 20 is lower than the bottom of the first louver 10, and there is a gap between the bottom of the second louver 20 and the bottom of the cavity 301.

[0074] like Figure 7As shown, in this embodiment of the invention, along the direction of gravity, i.e., along the Z-axis, the bottom of the first louver 10 is lower than the bottom of the second louver. Since the bottom plate of the cavity 301 is inclined, and along the positive X-axis, the distance from the bottom plate plane of the cavity 301 to the bottom plane of the first louver 10 gradually decreases. Along the positive X-axis, the first louver 10 and the second louver 20 are arranged sequentially within the cavity 301. Because there is a gap between the bottom of the first louver 10 and the bottom of the cavity 301, rainwater flowing down from the second louver 20 will flow onto the bottom plate of the cavity 301 and, along the inclined bottom plate plane, through the gap between the bottom of the first louver 10 and the bottom of the cavity 301, will be discharged from the louver device through the flow channel in the cavity 301, preventing water accumulation inside the louver device.

[0075] like Figure 8 As shown, along the direction of gravity, i.e. along the Z-axis, the bottom of the second louver 20 is lower than the bottom of the first louver 10. Conversely, along the positive X-axis, the second louver 20 and the first louver 10 are arranged sequentially inside the cavity 301. Since there is a gap between the bottom of the second louver 20 and the bottom of the cavity 301, rainwater flowing down from the first louver 10 will flow to the bottom plate of the cavity 301 and pass through the gap between the bottom of the second louver 20 and the bottom of the cavity 301 along the inclined bottom plate plane, thereby being discharged from the louver device through the flow channel in the cavity 301, preventing water accumulation inside the louver device.

[0076] Optionally, refer to Figure 1 The louver device also includes a filter 40, which is fixed to the surface of the first louver 10 and / or the surface of the second louver 20.

[0077] like Figure 1 As shown, the venetian blind device also includes a filter screen 40. When rainwater passes through the filter screen 40, the rainwater is blocked by the filter screen 40, thus forming water droplets on the filter screen 40. Due to the effect of gravity, the water droplets will flow along the filter screen 40 in the negative Z-axis direction, thereby preventing more rainwater from entering the interior of the venetian blind and improving the waterproof performance of the venetian blind device.

[0078] In the embodiments of this utility model, the filter screen 40 can be a steel mesh or a plastic mesh. When the filter screen 40 is a steel mesh, stainless steel can be selected. This improves the rigidity of the entire louver device, reduces deformation, and also provides strong corrosion resistance, extending the service life of the louver device. When the filter screen 40 is a plastic mesh, high-strength plastic can be selected. This not only reduces the overall weight of the louver but also ensures the strength of the filter screen, preventing damage.

[0079] In embodiments of this utility model, the filter screen 40 is fixed to the surface of the first louver 10 and / or the surface of the second louver 20. For example... Figure 1 As shown, when the filter 40 is located between the first louver 10 and the second louver 20, the filter 40 can be fixedly connected to both the first louver 10 and the second louver 20 simultaneously. When the filter 40 is located on the side of the first louver 10 along the negative X-axis, the filter 40 can only be fixedly connected to the first louver 10. When the filter 40 is located on the side of the second louver 20 along the positive X-axis, the filter 40 can only be fixedly connected to the second louver 20. When the filter 40 is located between the first louver 10 and the second louver 20, and is fixedly connected to both the first louver 10 and the second louver 20 simultaneously, the filter 40 will be more stable and less likely to fall off. The filter 40 can also be fixed to the air guide shroud 30 by a bracket.

[0080] Optionally, refer to Figure 1 The louver device also includes a dustproof cotton 50, which is embedded in the cavity 301.

[0081] like Figure 1 As shown, the louver device also includes a dustproof cotton 50. The dustproof cotton 50 not only effectively filters out moisture from humid air but also absorbs suspended solid particles in the air, while ensuring good ventilation to meet the ventilation and heat dissipation needs of the louver device. Embedding the dustproof cotton 50 within the cavity 301 serves two purposes: firstly, it secures the dustproof cotton 50 within the cavity 301; secondly, it allows moisture contained within the dustproof cotton 50 to seep into the cavity 301 and then drain out through the cavity 301, thereby further improving the waterproof performance of the louver device.

[0082] In the embodiments of this utility model, the main materials of the dustproof cotton 50 include cellulose, foam, polyurethane, etc. When the dustproof cotton 50 uses cellulose material, it has the characteristics of moisture absorption, mildew prevention, stain prevention, and insect prevention. It is usually used in high-requirement fields such as electronic products and precision instruments, and can effectively protect equipment from dust and pollution. Therefore, it can effectively protect the components in the electrical cabinet and improve the electrical safety of the electrical cabinet. The dustproof cotton 50 can also be replaced with a dustproof net. When the mesh density of the dustproof net is small, it can also achieve a good dustproof effect. Similar to the dustproof cotton 50, the dustproof net can also prevent dust, particles, and debris in the air from passing through the louver device and entering the interior of the electrical cabinet, thereby improving the electrical safety of the electrical cabinet.

[0083] Optionally, refer to Figure 1 and Figure 8The louver device further includes a partition 60. The cavity 301 includes a first opening 3011 and a second opening 3012, wherein the first opening 3011 is smaller than the second opening 3012. The partition 60 is located at the first opening 3011 and is connected to the first opening 3011. An exhaust vent 601 is provided on the surface of the partition 60.

[0084] like Figure 1 and Figure 8 As shown, the louver device also includes a partition 60. The cavity 301 includes a first opening 3011 and a second opening 3012, with the first opening 3011 being smaller than the second opening 3012. The partition 60 is located at the first opening 3011. The partition 60 effectively separates the louver device from the electrical cabinet and also protects the internal structure of the louver device. Connecting the partition 60 to the first opening 3011 makes the partition 60 more secure and reliable, preventing it from falling off. An exhaust vent 601 is provided on the surface of the partition 60, allowing outside air to be brought into the electrical cabinet for ventilation and heat dissipation, preventing the electrical cabinet from overheating and affecting electrical safety.

[0085] In the embodiments of this utility model, an exhaust fan or other ventilation device may be installed at the exhaust vent 601. When an exhaust fan is installed at the exhaust vent 601, the air can be blown evenly into the electrical cabinet, thereby reducing the temperature of the electrical cabinet and preventing direct airflow from damaging the components inside the electrical cabinet.

[0086] Optionally, refer to Figure 1 The louver device also includes a filter strip 70, and the filter 40 and the filter strip 70 are connected.

[0087] like Figure 1 As shown, the venetian blind device also includes a filter strip 70. The filter 40 and the filter strip 70 are connected, allowing the filter strip 70 to fix and maintain the stability of the filter, preventing the filter from moving or loosening during use. The filter strip 70 is typically installed on the edge of the filter 40 and can be fixed to the filter 40 by adhesive or screws, thus ensuring that the filter 40 will not move or loosen. This design ensures the stability and filtration effect of the filter 40, preventing the performance of the venetian blind device from being affected by the movement of the filter 40.

[0088] In the embodiments of this utility model, the material of the filter strip 70 can be activated carbon, which has a strong adsorption capacity and can adsorb harmful gases and particulate matter in the air. Therefore, the filter strip 70 can also have a filtration effect, thereby improving the filtration effect of the entire louver device.

[0089] This utility model also provides an electrical cabinet, which includes any of the aforementioned louver devices. The electrical cabinet also includes a door panel 80, on which the louver device is installed. An air inlet 801 is provided on the surface of the door panel 80. The installation of the louver device on the door panel 80, and the provision of the air inlet 801 on the door panel 80, allows outside air to directly enter the louver device through the air inlet 801, and then enter the electrical cabinet, achieving the effect of ventilation and heat dissipation.

[0090] Furthermore, the air inlet 801 can be designed with a mesh, serving both to allow air in and block rainwater, while also providing drainage. Specifically, the louver device is installed on the door panel 80 and is tightly connected to it, thus preventing rainwater from seeping into the electrical cabinet through the gap between the louver device and the door panel. The installation position of the louver device should be consistent with the position of the air inlet 801 to ensure that the air entering from the air inlet can be fully blown into the louver device. The first louver 10, the second louver 20, and the mesh on the air inlet 801 form a first flow channel. This flow channel has multiple S-shaped bends, providing the first barrier for rainwater entering the cabinet and reducing the kinetic energy of the water. In addition, the bottom of the mesh should be lower than the bottom louver of the first louver 10, thus forming a first drainage channel, which can quickly drain the water flowing into the first flow channel through the mesh at the air inlet 801.

[0091] Optionally, refer to Figure 10 The electrical cabinet also includes a waterproof strip 90, which is used to fix the louver device.

[0092] like Figure 10 As shown, the electrical cabinet also includes a waterproof strip 90, which secures the louver device to the door panel 80 of the electrical cabinet. The waterproof strip 90 surrounds the louver device, thus tightly connecting the louver device to the door panel 80, preventing moisture from entering the electrical cabinet through the air inlet 801. Furthermore, the waterproof strip 90 can be made of sheet metal or EPDM (ethylene propylene diene monomer) material.

[0093] It should be noted that louvered devices can be used in the field of ventilation and heat dissipation of electrical cabinets, as well as in other ventilation and heat dissipation fields such as houses and equipment. By using this type of louvered device, the ventilation, heat dissipation, waterproof and dustproof performance can be improved.
