Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, to low voltage switchboard, and more specifically, relates to an arrangement that is placed on the top surface of switchboard for improvement in ventilation.

BACKGROUND
[0002] In low voltage switchboard, the power distribution circuit is divided into two parts: the power control centre (PCC) on the upstream side and the motor control centre (MCC) on the downstream side. The power control centre distributes the power to different motor control centres which in turn distributes the power to different motor loads, and lighting loads using feeders/modules. The application decides the degree of protection (DOP) of the switchboard, if it is stationed at an outdoor location its construction is a double door with Ingres Protection IP55. In case it is stationed in a substation then ingress protection is IP42/43 is been provided with single-door construction. Substations can be equipped with a centralized cooling system or be a natural one based on the criticality of the applications.
[0003] The degree of Protection is an important parameter for the switchboard. For indoor installations, the preferred degree of protection is IP42/IP43. Generally, in a switchboard, IP43 is achieved with the help of a square-flap profile placed at a specific distance from the top of the panel, that acts as an outlet for the hot gases. It is understood that electrical equipment generates heat and the heat generated during the operation of the system needs to be dissipated out of the vertical. Such type of arrangement facilitates dissipating the hot air by convection and running the switchgear equipment smoothly and efficiently.
[0004] The square-flap profile that is been used at present has limitations and a few of them are listed as follows:
• The vent for dissipating the hot air from the vertical in the present profile is less and it acts as a bottleneck for free flow of air.
• The vent limits the flow as a result the switchgear runs hot, and affects the product performance
• The square flap of the profile is manufactured by a welding process
• Access for mounting on a top surface is tough
• The assembly time required is on the higher side
[0005] Therefore, it is desired to overcome the drawbacks, shortcomings, and limitations associated with existing solutions, and develop a cost-effective ventilation arrangement that enhances the vent profile with a G-legged structure that facilitates an efficient dissipation of hot air.

The description of terms and features related to the present disclosure shall be clear from the embodiments that are illustrated and described; however, the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents of the embodiments are possible within the scope of the present disclosure. Additionally, the invention can include other embodiments that are within the scope of the claims but are not described in detail with respect to the following description.
[0036] FIG. 1 illustrates an exemplary prospective view of the ventilation arrangement of the switchboard, in accordance with an embodiment of the present disclosure.
[0037] Referring to FIG. 1, ventilation arrangement 100 of the switchboard is disclosed. The ventilation arrangement 100 can include hood 102, one or more components (104, 106), vertical element 108, frame 110, a plurality of louvers 112 (also referred to as molded louvers 112, herein) and one or more doors114 (also referred to as doors 114, herein). The vertical arrangement 100 having the hood 102 characterized by a profile similar to that of an inverted funnel, can include one or more internal components joined through a riveting process.
[0038] The hood 102 accommodated on at least one surface e.g., top surface of the switchboard configured to control airflow within the switchboard. It is configured to encase internal components and directs the expulsion of hot air, contributing to the overall ventilation process. The hood 102 encapsulates one or more internal components (also referred to as internal components, herein) and facilitates the directed expulsion of hot air generated by electrical equipment inside the vertical element 108, thereby enhancing the overall ventilation process. The one or more internal components of the hood 102 are interconnected using a set of rivets, where the internal components include a flap 202, a mesh 204, and a G-leg profile element 206 ( also referred to as G-leg 206, herein) shown in FIG. 2A. The flap is configured to generate pressure within the hood 102 to induce a jet effect. The mesh 204 maintains the required pressure inside the hood 102 for the jet effect and the G-leg profile element 206 is configured to direct the flow of the hot air from the vertical element 108 towards the flap 202
[0039] In an embodiment, one or more components of the ventilation arrangement 100 can include a first component 104 and a second component 106 that is configured to facilitate in directing an upward movement of hot air within the switchboard. These components are configured as plain sheets when functioning independently as vertical elements 108 and are perforated when integrated into the transport panel unit. Their design and placement optimize the system's efficiency in facilitating the desired airflow.
[0040] The plurality of louvers 112 is positioned on one or more doors 114 within the switchboard, configured to regulate airflow, thereby preventing ingress of undesired elements and promoting efficient air circulation. The molded louvers 112 define openings or slits in a structure that are created through a molding process. The molded louvers 112 are strategically positioned on the doors to serve as controlled openings for the intake of fresh air.
[0041] The frame 110 is strategically positioned to reinforce the base of the vertical element 108. This frame 110 is specifically provided to enhance the structural integrity of the base of the vertical element 108 and prevent damage during the transportation of the switchboard. The base of the present disclosure facilitates the collection of hot gases, while the middle entity supports airflow, creating the jet effect through a vent in the top entity. The top entity is designed with openings featuring the mesh, ensuring the maintenance of the necessary pressure to generate the jet effect. This resultant jet effect expedites the dissipation of hot air at a rate 1.5 times faster than the previous square-flap profile, due to the naturally induced airflow prompted by the distinctive arrangement of intermediate barriers. This, in turn, contributes to maintaining a lower ambient temperature within the vertical element, effectively cooling electrical switchgear.
[0042] Further, the vertical element 108 is installed with VFD, soft drives and capacitors which are sources of heat, where a fan is mandatory. The profile of hood 102 facilitates fixing the fan if needed to push the hot air outside without any additional components to be fitted inside the vertical element 108.
[0043] In an implementation, the hot air generated by the electrical equipment inside the vertical element 108 is directed by the G-leg profile element 206, and fresh air is drawn in through the plurality of louvers 112 on the one or more doors 114, resulting in a cyclic process that reduces power consumption for the vertical element 108 and enhances material efficiency for sustainability in the switchboard with any given rating.
[0044] For example, the present invention contemplates the ventilation arrangement for the switchboard, where the expulsion of hot air generated by electrical equipment within the vertical element 108 is directed by the G-leg profile element 206. Simultaneously, a cyclic process is initiated, wherein fresh air is drawn in through the plurality of louvers 112 positioned on front doors 114. This dynamic airflow management results in a reduction of power consumption for the vertical element 108. Furthermore, the arrangement enhances material efficiency, contributing to sustainability in the switchboard across various operational ratings.
[0045] FIG. 2A illustrates an exemplary prospective isometric view of the hood, in accordance with an embodiment of the present disclosure. The hood 102 is made up of three components the flap 202, the mesh 204 and the G-leg 206. Each component of the hood 102 is interconnected using rivets. The use of rivets for interconnecting these components ensures structural integrity and stability within the hood, contributing to the overall effectiveness of the ventilation arrangement for the switchboard.
[0046] In an embodiment, the flap 202 is configured to cover the mesh 204, thereby facilitating the generation of pressure within the hood 102 to induce the occurrence of a jet phenomenon (also referred to as the jet effect, herein). The mesh 204 serves a dual purpose in maintaining the required pressure inside the hood 102 for the jet phenomenon. Firstly, it actively contributes to the creation and sustenance of pressure within the hood 102. Secondly, it acts as a barrier preventing the entry of dust particles from the external environment into the vertical element 108. The G-leg 206 profile is identified as a critical component with multiple functions in the ventilation arrangement 100. The G-leg 206 is configured to maintain the pressure required within the hood 102. Furthermore, the G-leg 206 serves as a guide, directing the flow of hot air from the vertical element 108 towards the flap 202.
[0047] FIG. 2B illustrates an exemplary prospective isometric view of the G-leg profile, in accordance with an embodiment of the present disclosure. The G-leg 206 is configured to maintain the pressure required within the hood 102. Furthermore, the G-leg 206 serves as a guide, directing the flow of hot air from the vertical element 108 towards the flap 202.
[0048] The G-leg 206 can include a first flange 210, an angular profile 212, a second flange 214, and a window 216. The first flange 210 aids in positioning the flap 202 at a specific desired location. The angular profile 212 contributes to creating the jet effect, enhancing the airflow by pushing a volume of air 1.2 times through the window 216 compared to the existing arrangement. The second flange 214 serves to secure the hood 102 to the vertical element 108.
[0049] FIG. 2C is a front view of the hood illustrating the direction of airflow, in accordance with an embodiment of the present disclosure. In FIG. 2C, the operational principle of the present disclosure is illustrated, functioning on the basis of convection. As the system runs, the air inside the vertical element 108 is heated. The G-leg 206 directs the heated air and expels it through the window 216. Simultaneously, fresh air is drawn in through the molded louvers 112 located on the front door 114 at the bottom of the vertical element 108, serving as the inlet.
[0050] This process operates cyclically, where the heated air rises, guided by the G-leg 206, and is replaced by cool fresh air entering through the louvers 112. The cycle activates as the air continuously gets heated and moves upwards, propelled by the influx of fresh air. The net result of this convection-driven ventilation arrangement is a 10% reduction in power consumption for the vertical element 108 in the system with any given rating. Additionally, the material consumption for the specific rating becomes more economical, rendering the solution sustainable. The present disclosure leverages convection to enhance airflow, thereby improving energy efficiency and promoting a more sustainable and cost-effective solution for the vertical element in the system.
[0051] Thus, the present invention overcomes the drawbacks, shortcomings, and limitations associated with existing solutions, and provides the ventilation arrangement that introduces a G-legged structure to enhance the vent profile, promoting efficient hot air dissipation by 1.5 times through the jet effect. The ventilation arrangement significantly reduces the internal temperature of switchgear by 5 to 8 degrees, ensuring safer and optimal operating conditions for components. Additionally, it maintains the ambient temperature within the switchboard at desirable levels, preventing heat buildup that could compromise equipment performance and lifespan. The configuration of the airflow arrangement optimizes linkwork for switchboard ratings, ensuring each component receives sufficient cooling, enhancing overall efficiency and reliability. The arrangement allows effective utilization of panel volume, fostering a more compact and space-saving design. Beyond these benefits, the ventilation arrangement contributes to energy efficiency by dissipating heat and reducing internal temperatures, leading to a lowered carbon footprint. Its design also facilitates easier component assembly, streamlining manufacturing processes, and promoting quicker assembly times, thereby contributing to cost savings and improved production efficiency in switchboard manufacturing.
[0052] It will be apparent to those skilled in the art that the ventilation arrangement 100 of the disclosure may be provided using some or all of the mentioned features and components without departing from the scope of the present disclosure. While various embodiments of the present disclosure have been illustrated and described herein, it will be clear that the disclosure is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the disclosure, as described in the claims.
