Description

Technical Field

[0001] This disclosure relates to a ventilation hood installed in a enclosure for housing electrical equipment. Background Technology

[0002] Patent document 1 discloses a ventilation hood in a ventilation duct that prevents wind and rain from penetrating the interior of the hood. The hood covering the opening for ventilation is box-shaped.

[0003] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2013-174434 Summary of the Invention

[0004] The problem that the invention aims to solve However, when the ventilation hood is installed within the container, it protrudes from the surface of the container. Therefore, during transport, the dimensions of the container, including the ventilation hood, may not meet road traffic regulations. In this case, new transportation costs are incurred because the container is transported with the ventilation hood removed. Furthermore, the cost is further increased due to the installation work required to attach the ventilation hood to the container at the destination.

[0005] One object of this disclosure is to provide a ventilation hood that can be installed on a transport container.

[0006] Methods for solving problems One aspect of this disclosure relates to a ventilation hood installed within a housing for electrical equipment. The ventilation hood is composed of multiple metal plates and is configured to be foldable. One of the metal plates is fixedly mounted to the housing. The metal plates have a nested structure. During ventilation within the housing, one or more other metal plates, excluding the first one, unfold from the first metal plate to connect the interior and exterior of the housing.

[0007] Invention Effects According to this disclosure, the ventilation hood is composed of multiple metal plates and is configured to be foldable. One of the metal plates is fixedly installed in the housing, and the multiple metal plates have a nested structure during ventilation. One or more other metal plates, excluding the first metal plate, unfold from the first metal plate to connect the interior and exterior of the housing. Therefore, the housing can be transported with the ventilation hood installed in the housing. This reduces the costs associated with transporting the housing and on-site operations.

[0009] Figure 2This is a diagram illustrating a first structural example of a ventilation hood.

[0010] Figure 3 This is a diagram illustrating a second structural example of the ventilation hood. Detailed Implementation

[0011] The ventilation hood of the present disclosure will be described with reference to the accompanying drawings. Furthermore, common elements in all figures are labeled with the same reference numerals, and repeated descriptions are omitted.

[0012] 1. Overview of Ventilation Box Figure 1 (A) and Figure 1 Figure (B) is a schematic diagram illustrating the ventilation enclosure 1. The ventilation enclosure 1 includes a housing 2 and a ventilation hood 10. The housing 2 is a transportable enclosure installed outdoors. The size of the housing 2 varies. For example, the housing 2 can also be a shipping container conforming to ISO standards. The housing 2 is also referred to as the casing. The housing 2 houses electrical equipment 5. Examples of electrical equipment 5 include power receiving devices for supplying power to loads such as factories (e.g., devices driven by DC power, devices equipped with inverters, etc.), and power conditioners for solar panels.

[0013] The ventilation hood 10 is used to ventilate the air inside the enclosure 2. One purpose of the ventilation hood 10 is to cool the internal temperature of the enclosure 2. For example, since electrical equipment 5 is housed inside the enclosure 2, the internal temperature of the enclosure 2 rises during the operation of the electrical equipment 5. To cool the internal temperature of the enclosure 2, the ventilation hood 10 is provided, for example, at the air intake and exhaust ports of the enclosure 2. Thus, by using a fan installed inside the enclosure 2 to draw in outside air and expel the hot air inside the enclosure 2 to the outside, the internal temperature of the enclosure 2 can be cooled. In addition, the ventilation hood 10 prevents rain, dust, snow, etc., from entering when drawing in outside air. This prevents malfunctions of the electrical equipment 5.

[0014] 2. Specific examples of ventilation hoods As specific examples of the ventilation hood 10 that can be installed on the container 2 during transport, two examples are described below.

[0015] 2-1.The first example Figure 2 (A) and Figure 2 Figure (B) is a diagram illustrating a first structural example of the ventilation hood 10. In the first structural example, as shown... Figure 2 As shown in (A), the ventilation hood 10 is composed of a plurality of metal plates 11. The plurality of metal plates 11 are, for example, composed of metal plate 11A, metal plate 11B, metal plate 11C and metal plate 11D. The plurality of metal plates 11 have, for example, a door-shaped shape and have an inclined top plate.

[0016] Multiple metal plates 11 have a nested structure, and each metal plate 11 has a different height. Figure 2 In the example shown in (A), the height decreases in the order of metal plates 11A, 11B, 11C, and 11D.

[0017] like Figure 2 As shown in (B), one of the plurality of metal plates 11 (e.g., metal plate 11A) is fixedly installed in the housing 2. Figure 2 As shown in (C), during ventilation within the enclosure 2, one or more other metal plates (e.g., metal plates 11B, 11C, 11D) besides one metal plate 11 (e.g., metal plate 11A) unfold from one metal plate 11 (e.g., metal plate 11A) to connect the interior and exterior of the enclosure 2. Specifically, the other one or more metal plates (e.g., metal plates 11B, 11C, 11D) are mounted to be movable in a direction orthogonal to the side of the enclosure 2 on which one metal plate (e.g., metal plate 11A) is mounted. The other one or more metal plates (e.g., metal plates 11B, 11C, 11D) unfold sequentially away from one metal plate (e.g., metal plate 11A).

[0018] Thus, the ventilation hood 10 of the first structural example is configured to be foldable. Figure 2 (B) shows the configuration with the ventilation hood 10 folded. Figure 2 (C) shows the configuration with the ventilation hood 10 deployed. This allows the housing 2 to be transported while the ventilation hood 10 is installed in the housing 2.

[0019] Furthermore, the ventilation hood 10 may also have a locking mechanism 12 for securing adjacent metal plates 11 when the ventilation hood 10 is deployed. Thus, the ventilation hood 10 can maintain its deployed state even when affected by disturbances such as wind.

[0020] 2-2. Second example Figure 3 (A) Figure 3 (B) and Figure 3 Figure (C) is a diagram illustrating a second structural example of the ventilation hood 10. In the second structural example, as... Figure 3 As shown in (A), the ventilation hood 10 is composed of a plurality of metal plates 13. The plurality of metal plates 13 are, for example, composed of metal plates 13A, 13B, 13C, and 13D. The plurality of metal plates 13 have a top plate and a door-shaped form. Furthermore, the plurality of metal plates 13 have a fan-shaped form when viewed from the side.

[0021] Multiple metal plates 13 have a nested structure, and each metal plate 13 has a different height. Figure 3In the example shown in (A), the height decreases in the order of metal plates 13A, 13B, 13C, and 13D.

[0022] like Figure 3 As shown in (B), one of the plurality of metal plates 13 (e.g., metal plate 13A) is fixedly mounted to the housing 2. Figure 3 As shown in (C), during ventilation within the enclosure 2, one or more other metal plates (e.g., metal plates 13B, 13C, 13D) besides one metal plate 13 (e.g., metal plate 13A) unfold from one metal plate 13 (e.g., metal plate 13A) to connect the interior and exterior of the enclosure 2. Specifically, one or more metal plates 13 (e.g., metal plates 13B, 13C, 13D) are mounted so as to be able to rotate about a rotation axis 14 provided on one metal plate 13 (e.g., metal plate 13A) and unfold in a manner that rotates sequentially relative to one metal plate 13 (e.g., metal plate 13A).

[0023] Thus, the ventilation hood 10 of the second structural example is configured to be foldable. Figure 3 (B) shows the configuration with the ventilation hood 10 folded. Figure 3 (C) shows the configuration with the ventilation hood 10 deployed. This allows the housing 2 to be transported while the ventilation hood 10 is installed in the housing 2.

[0024] Furthermore, the metal plate 13 fixedly installed in the enclosure 2 may be the metal plate 13 with the lowest height (e.g., metal plate 13D). In this case, one or more other metal plates 13 may be metal plates 13 other than the metal plate 13 with the lowest height (e.g., metal plates 13A, 13B, 13C). Alternatively, during ventilation in the enclosure 2, one or more other metal plates 13 (e.g., metal plates 13A, 13B, 13C) may be deployed in a manner that moves away from one metal plate 13 (e.g., metal plate 13D) in turn to connect the interior and exterior of the enclosure 2.

[0025] Furthermore, the ventilation hood 10 may also have a locking mechanism 12 for securing adjacent metal plates 13 when the ventilation hood 10 (one or more metal plates 13) is deployed. Thus, the ventilation hood 10 can maintain its deployed state even when affected by disturbances such as wind.

[0026] 3. Effects According to this disclosure, the ventilation hood is composed of multiple metal plates and is configured to be foldable. One of the metal plates is fixedly installed in the housing, and the multiple metal plates have a nested structure during ventilation. One or more other metal plates, excluding the first metal plate, unfold from the first metal plate to connect the interior and exterior of the housing. Therefore, the housing can be transported with the ventilation hood installed in the housing. This reduces the costs associated with transporting the housing and on-site operations.
