Description

Technical field The present disclosure relates to a system and a method for cooling electrical components. State of the art Electrical components, such as inductors, are widely used in a variety of electronic applications, including power conversion devices, power supply devices, sensor systems, and the like. One of the challenges in the design of electrical components is managing the heat they generate, for example, due to power losses within those components. When an electric current flows through an electrical component, it typically generates heat due to the resistance of the wire within the component. This heat must generally be dissipated to prevent the component from overheating and shortening its lifespan. Furthermore, the generated heat can also affect one or more parts surrounding the electrical component, such as...an insulating material layered around an induction coil, which also leads to a reduced lifespan for these parts. US 2022 / 0192047 A1 relates to a power conversion device comprising an AC power connector, at least one DC power connector, a chassis, at least one power conversion module mounted in the chassis that can be connected to the AC and the at least one DC power connector via off-board conductors, and a module heat sink attached to each of the at least one power conversion module for cooling the module. The off-board inductors are mounted in the chassis together and separately from the modules, with one or more induction heat sinks and coolant circulators for cooling the inductors. Furthermore, US 4 894 749 A describes an optionally equipped device, such as a computer, that is not fully equipped with optional circuit boards and has filler boards connected to free slots. Furthermore, DE 20 2016 102 587 U1 describes a three-phase filter, wherein the filter has for each phase an input terminal, an output terminal, a first coil, a second coil and a capacitor, wherein for each of the three phases the input terminal is electrically connected to the output terminal via the first coil, wherein for each of the three phases the first coil is connected between a connection point and the input terminal, wherein the connection points of the three phases are electrically connected via the three second coils and the three capacitors in a star and / or delta configuration, wherein the filter has a housing containing a first coil block with the first coils of the three phases and a second coil block with the second coils of the three phases, wherein the housing has a first side and a second side opposite the first side.wherein the first coil block and the second coil block are arranged along a line between the first side and the second side, wherein a fan is arranged on the first side of the housing for cooling the first coil block and the second coil block, wherein the larger of the first and second coil blocks is arranged between the fan and the smaller of the first and second coil blocks. Furthermore, GB 2 587 618 A describes a containerized power supply unit consisting of a container, an electrical storage or power generation system, and a temperature control system. The container has air ducts extending from the outside to the inside. A lining, guide, or cover is fitted on the inside of the container around the air ducts. The cover directs the airflow between the air duct and the temperature control system. A method for assembling, repairing, or manufacturing the same is also described.

Detailed description Specific embodiments or features will now be discussed in detail, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals are used in all drawings to refer to identical or similar sections. With reference to Fig. 1, an exemplary containerized energy storage system 100 is shown. The containerized energy storage system 100 contains a variety of electrical components 102. The electrical components 102 can be those used in any electrical circuit (not shown). For example, but not limited to, the electrical components 102 can correspond to inductors 104. As shown in Fig. 2, each electrical component 102 can include a core 106 (e.g., an electrical core consisting of electrical wires, etc.) and an outer casing 108 that surrounds the core 106 and defines a space 110 with it. Although the inductor 104 is discussed in the present disclosure, the electrical component 102 can include any component that generates heat and requires cooling for efficient operation. Referring again to Fig. 1, the containerized energy storage system 100 can include a container 116 that defines an internal volume 112 for accommodating the electrical components 102. The container 116 can be a rectangular container with one or more walls, for example, a first container wall 120, a second container wall 122 opposite the first container wall 120, and a third container wall 124 extending between the first container wall 120 and the second container wall 122, as shown. The container 116 can also include a container bottom 126 connected to each of the first container wall 120, the second container wall 122, and the third container wall 124. Furthermore, the container 116 can include a fourth container wall and a roof, the fourth container wall and roof being shown in Fig.Figure 1 is not shown to illustrate and describe one or more details associated with the interior of the container 116. Additionally, the container 116 includes an inlet opening 128, e.g., on the first container wall 120, to draw air into the container 116 to cool the electrical components 102, and an outlet opening 130, e.g., on the second container wall 122, which may contain one or more venting devices, such as an exhaust fan (not shown), to vent or release a volume of air used to cool the electrical components 102 from the container 116. The containerized energy storage system 100 further includes a cooling system 140 for the electrical components 102. Although not limited to this, the cooling system 140 can be arranged on the bottom of the container 126. The cooling system 140 can be used to cool the electrical components 102 and to maintain their temperature at an optimal level or at a level suitable for their operation. The cooling system 140 is now described in more detail in the following disclosure. Referring to Figs. 2, 3 to 4, the cooling system 140 comprises a housing 160 with a base 142 and a number of outer walls, for example, a first outer wall 144, a second outer wall 150, a third outer wall 152 (shown in Figs. 3 and 4), and a fourth outer wall 154 (shown in Figs. 3 and 4). One or more of the first outer wall 144, the second outer wall 150, the third outer wall 152, and the fourth outer wall 154 can be arranged upright with respect to the base 142. The first outer wall 144 can be arranged opposite the second outer wall 150, and the third outer wall 152 can be arranged opposite the fourth outer wall 154 (shown in Figs. 3 and 4). Together, the outer walls 144, 150, 152, 154 can give the housing 160 an essentially rectangular configuration.The cooling system 140 further comprises internal side walls, such as a first side wall 156, a second side wall 158, a third side wall 146, and a fourth side wall 148. The first side wall 156 and the second side wall 158 can be arranged opposite each other. The first side wall 156 can be connected to the first outer wall 144, while the second side wall 158 can be connected to the second outer wall 150. The first side wall 156 can be inclined with respect to the third side wall 146, while the second side wall 158 can be inclined with respect to the fourth side wall 148. According to various embodiments, the first side wall 156 and the second side wall 158 can each define a first angle 162 and a second angle 164 with respect to the third side wall 146 and the fourth side wall 148 of the cooling system 140. The first angle 162 can be equal to the second angle 164. The outer walls 144, 150, 152, 154, the inner walls 146, 148, 156, 158, and the base 142 can collectively define a plenum 166 within the housing 160 of the cooling system 140. The plenum 166 can contain various chambers 180, 182, 184, which are defined within the housing 160 of the cooling system 140. For example, a primary chamber 180 is formed by a section of the base 142, the third side wall 146, the fourth side wall 148, a section of the third outer wall 152, and a section of the fourth outer wall 154. In this way, the base 142, the third side wall 146, the fourth side wall 148, a section of the third outer wall 152, and a section of the fourth outer wall 154 can enclose a volume of the primary chamber 180.A secondary chamber 182 is formed by the first side wall 156, the second side wall 158, a section of the third outer wall 152, and a section of the fourth outer wall 154 in conjunction with respective sections of the first outer wall 144 and the second outer wall 150. According to various embodiments, since the first side wall 156 and the second side wall 158 can be inclined relative to the third side wall 146 and the fourth side wall 148, the secondary chamber 182 can define a structural section 186 that diverges away from the primary chamber 180 and outwards, as shown. Furthermore, an auxiliary chamber 184 can be formed by the first outer wall 144, a section of the base 142, the third side wall 146, the first side wall 156, a section of the third outer wall 152, and a section of the fourth outer wall 154. The auxiliary chamber 184 can form a passage 194 for the entry of an airflow into the housing 160. The auxiliary chamber 184 can define an inlet opening 190 for the passage 194 and an outlet opening 192 for the passage 194. The inlet opening 190 and the outlet opening 192 can each be provided on the first outer wall 144 and the third side wall 146 of the cooling system 140, respectively. The cooling system may also include a fan 196. The fan 196 may be located at the outlet opening 192 of the third side wall 146 in the primary chamber 180. For example, the fan 196 may be installed on a side 198 of the third side wall 146 facing the primary chamber 180. The fan 196 may be located inside the primary chamber 180, but is not limited to this. The fan 196 may be a centrifugal fan that utilizes centrifugal force to generate an airflow and move the airflow out of the primary chamber 180. Although not shown, other types of fans may also be considered, and the fan 196 is not limited to a centrifugal fan. Therefore, it is noted that the blower 196 can contain any blower capable of drawing an airflow from the auxiliary chamber 184 through the passage 194 into the primary chamber 180 and then pushing and moving the airflow from the primary chamber 180 into the secondary chamber 182 of the plenum 166. The cooling system 140 may further include a diffuser 200. The diffuser 200 can disperse the airflow received from the secondary chamber 182 and distribute the airflow evenly towards each electrical component 102 located on a platform 208 (discussed later) of the cooling system 140. The diffuser 200 may be in fluid communication with the secondary chamber 182 and located upstream of the secondary chamber 182 or downstream of the secondary chamber 182 along the airflow. In some embodiments, the diffuser 200 may be coupled to one or more of the outer walls 144, 150, 152, 154 to be defined as facing the secondary chamber 182 or at one end thereof. The diffuser 200 can include a perforated plate 202 (see Fig. 2, Fig. 3 to Fig. 4) which defines several airflow openings 204 (see Fig. 3 and Fig. 4).The airflow openings 204 can correspond to holes that may have the same size and shape, with variations in the size and / or shape of one or more airflow openings 204 in relation to one or more other airflow openings 204 of the diffuser 200 being possible. In an example, as shown in Fig. 3, the diffuser 200 can define the following: a first segment 212 adjacent to the first outer wall 144, a second segment 214 adjacent to the second outer wall 150, and an intermediate segment 216 that can define a central area 188 of the diffuser 200 and extends between the first segment 212 and the second segment 214. In some embodiments, the cross-sectional areas of the airflow openings 204 in the intermediate segment 216 may be smaller than the cross-sectional areas of the airflow openings 204 of the first segment 212 and the second segment 214. In some embodiments, the cross-sectional areas of the airflow openings 204 may increase (e.g., gradually) from the central region 188 to the corresponding and opposite ends of the diffuser 200, as defined by each of the first segments 212 and second segments 214. Referring to Figs. 2, 3, 4 to 5, the cooling system 140 can further include the platform 208. The platform 208 can be used to mount the electrical components 102. In an exemplary embodiment, the electrical components 102 can be arranged in a two-dimensional arrangement 210 on the platform 208. The airflow openings 204 of the diffuser 200 and / or the diffuser 200 itself can be arranged at a uniform offset T (shown in Figs. 2 and 4) with respect to the two-dimensional arrangement 210 of the electrical components 102 mounted on the platform 208. Furthermore, the diffuser 200 can be arranged between the secondary chamber 182 of the plenum 166 and the platform 208. According to some embodiments, the platform 208 can include a number of spaced-apart supports 220 arranged in a planar configuration. The supports 220 can be positioned further forward or aft of the diffuser 200 along an airflow direction. In some embodiments, the supports 220 can be positioned forward of the diffuser 200 along an airflow direction by coupling ends or edges 222 of the supports 220 to a section of the third outer wall 152 and a section of the fourth outer wall 154. The coupling can be achieved by welding and / or the use of fasteners (e.g., threaded connections) 226 (shown in Figures 3 and 4), but is not limited to these methods. The supports 220 can be made of a variety of materials, such as metal or an alloy, to provide stiffness and stability for mounting the electrical components 102 on the platform 208. In some embodiments, the platform 208 can include connecting elements 228. The connecting elements 228 can define a mounting surface 224 for mounting the electrical components 102 on the platform 208. The connecting elements 228 can be designed transversely to the spaced supports 220 to define a grid formation 230 (shown in Fig. 4 and Fig. 5) with the spaced supports 220. In some embodiments, each grid 230' (only one is marked, see Fig. 5) in the grid formation 230 defines a location 244 (see Fig. 5) on the platform 208 for mounting one or more electrical components 102, and furthermore, each grid 230' formed by the connecting elements 228 can also provide an unobstructed passage 248 (see Fig. 5).5) define through which the airflow can pass to reach the corresponding electrical component 102 and then continue through the free space 110 associated with the corresponding electrical component 102. The connecting elements 228 can be securely coupled to the supports 220 by using various fastening mechanisms 234, such as, but not limited to, the use of fasteners 236 (shown in Figs. 3 and 5). The connecting elements 228 can be configured to mount the electrical components 102 onto them. The connecting elements 228 can be designed to arrange the electrical components 102 on the platform 208 in a variety of configurations. For example, the connecting elements 228 can be configured to arrange the electrical components 102 in the two-dimensional arrangement 210 on the platform 208. For this purpose, the platform 208 can be designed to be planar.The electrical components 102 can be mounted on the connecting elements 228 using various fastening mechanisms 240, for example, using the fasteners 238 (shown in Fig. 3). In some embodiments, the connecting elements 228 can be adjustable or removable with respect to the spaced supports 220, allowing for individual customization of the platform 208 and the accommodation of different types or sizes of electrical components 102 on the platform 208. In some embodiments, one or more of the supports 220 (e.g., the supports 220`) can simply support the weight of the platform 208 and the electrical components 102. Referring again to Figs. 2, 3 to 4, the cooling system 140 further includes a cover 242 that defines several slots 246 (shown in Figs. 3 and 4). The slots 246 can accordingly accommodate the electrical components 102. It is noted that when the electrical components 102 are appropriately accommodated in the slots 246, the cover 242 can enclose each electrical component 102 and provide a seal around each electrical component 102. It is possible for the slots 246 to define an interference fit with the electrical components 102. The dimensions and size of each slot 246 can be configured to correspond to the size of each electrical component 102.In some embodiments, the dimensions and size of one or more slots 246 can be modified and adapted to surround electrical components 102 of different shapes and sizes. In some embodiments, the press fit and / or the seal can be omitted. In such cases, the unobstructed passages 248 can direct at least a portion of the airflow to and around the electrical components 102 (e.g., also around the outer casing 108). In some embodiments, the cover 242 in the cooling system 140 can be omitted entirely, and even in such cases, the airflow can be directed through the unobstructed passages 248 to and around the electrical components 102 (e.g., around the outer casing 108). It becomes clear that the various elements of the cooling system 140, e.g. the primary chamber 180 and the secondary chamber 182, in conjunction with the diffuser 200 and the cover 242, can jointly define an arrangement 250 of the cooling system 140 that directs the airflow from the blower 196 towards the platform 208 and distributes the airflow evenly to each electrical component 102, so that the airflow passes through the free space 110 assigned to each electrical component 102. Understandably, the direction of the airflow is enabled by the primary chamber 180 and the secondary chamber 182 of the plenum 166, and, in particular, the structural section 186, which diverges outwards and away from the primary chamber 180 towards the platform 208, directs the airflow from the primary chamber 180 towards the platform 208. The free passages 248 in conjunction with the slots 246 defined by the cover 242 define dedicated flow channels 218 (see Fig.4) of the arrangement 250 corresponding to the electrical components 102, so that each electrical component 102 can absorb the airflow evenly to achieve uniform cooling. Commercial applicability To cool the electrical components 102, an operator can use an exemplary method, which is now described with reference to a flowchart 600 in Fig. 6. References to Figs. 1, 2, 3, 4 to 5 may also be used. Method 600 includes the use of the blower 196 to generate an airflow (step 602). Method 600 further includes mounting the electrical components 102 on the platform 208 (step 604). Method 600 further includes providing the arrangement 250, including the plenum 166, to direct the airflow through the plurality of unobstructed passages 248 onto and around the electrical component 102 (step 606). As part of an exemplary process for cooling the electrical components 102 using the previously mentioned exemplary elements of the cooling system 140, the blower 196 can be driven to run and create a vacuum (e.g., negative air pressure) within the auxiliary chamber 184, thereby drawing air from the inlet opening 128 of the container 116 and directing it into the inlet opening 190 of the auxiliary chamber 184. This drawn-in air flows through the duct 194 and is then fed to the outlet opening 192 of the cooling system 140. As the blower 196 continues to run, it draws in air and generates an airflow that is then directed into the primary chamber 180, creating a positive pressure (e.g., positive air pressure) in the primary chamber 180. This overpressure causes the airflow generated by the blower 196 to be forced out of the primary chamber 180 into the secondary chamber 182, e.g. at an assigned velocity.In secondary chamber 182, the airflow is widened due to the diverging structural section 186 of secondary chamber 182, and its path or velocity is relatively slowed, allowing the airflow to spread over an area of ​​secondary chamber 182. The continuous thrust of the air pressure forces the airflow collected in secondary chamber 182 towards the diffuser 200. At the diffuser 200, the airflow passes through the airflow openings 204 and divides into several airflow streams. The diffuser 200 also diffuses the airflow received from secondary chamber 182 and distributes it evenly to each electrical component located on platform 208. At this point, the multiple airflow streams pass through the unobstructed passages 248 to the electrical components 102.to each electrical component 102, and in particular up to the free space 110 defined by each electrical component 102, in order to pass through the free space 110 defined by each electrical component 102. In fact, the arrangement 250 distributes the airflow evenly to each electrical component 102, so that the airflow passes through the free space 110 assigned to each electrical component 102. Once the airflow passes through the openings 110, it can be forced out of each electrical component 102 into the internal volume 112 of the container 116 and discharged. By actuating one or more vents located at the exhaust opening 130, this released air can then be forced out of the container 116. To mitigate or eliminate the possibility of this released air being drawn back into the cooling system 140 and impairing its cooling efficiency (since the released air can carry heat from the electrical components 102 and may be hotter than the air drawn in by the blower 196 from the inlet opening 190), the cover 242 provides a seal (e.g., by press fit) around each electrical component 102 to block or restrict the entry of the released air into the cooling system 140.In some embodiments, a channel (not shown) can be coupled between the inlet port 128 and the inlet opening 190 to separate the air drawn in by the blower 196 from the air discharged by the cooling system 140. As previously described, the cooling system 140 provides the arrangement 250, which directs the air evenly to each electrical component 102. By defining the dedicated flow channels 218, the arrangement 250 ensures that the airflow is supplied evenly and directed through the free spaces 110 assigned to each electrical component 102. This passage of the airflow dissipates the heat trapped in the spaces 110, thereby efficiently cooling the electrical components 102 and increasing their service life. Furthermore, the cooling achieved in this way (e.g., the uniform cooling) also enables optimization of the electrical components 102 for operation and / or timely inspection and / or maintenance.Furthermore, the parts or elements of the cooling system 140, as described above, are easy to obtain, manufacture and / or construct, so that the cooling system 140 can be built relatively easily, i.e. with a minimum of expertise, and at relatively low cost. It is obvious to those skilled in the art that various modifications and variations can be made to the method and / or system of the present disclosure without deviating from the scope of the disclosure. Other embodiments will be apparent to those skilled in the art from a review of the patent specification and the practice of the method and / or system disclosed herein. It is intended that the patent specification and the examples given are to be considered merely exemplary, with the true scope of the disclosure being specified by the following claims and their equivalents.
