Description

Technical Field

[0001] This utility model relates to the field of enclosure ventilation and heat dissipation technology, and in particular to a louver, enclosure, box-type power station and box-type house. Background Technology

[0002] The prefabricated power station of this application consists of a prefabricated enclosure and electrical or electronic equipment placed therein to achieve the set functions, including prefabricated substations, prefabricated charging stations, prefabricated energy storage stations, prefabricated ring main units, communication base stations, computer stations, etc.

[0003] The container house described in this application consists of a container body and electrical equipment or furniture placed inside it to achieve the set function, including RVs, yachts, container houses, pavilions, etc.

[0004] For ventilation, heat dissipation, and protection purposes, prefabricated substations and prefabricated houses are typically equipped with louvers on the enclosure. However, existing louvers, in order to achieve IP34 or higher protection levels, use a labyrinthine air duct composed of several blades, resulting in a complex structure, high air resistance, and high cost. To achieve IP3X or IP4X protection, louvers usually have a perforated plate added to the inside. This perforated plate is easily clogged by dust and difficult to clean from the outside. Utility Model Content

[0005] The purpose of this utility model is to provide a louver, a box, a box-type power station, and a box-type house to solve the shortcomings of the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model discloses a louver, comprising a blade section and a mesh section. The blade section is located on the inner side of the louver and includes several blades arranged vertically side by side. Each blade includes intersecting first and second blades. The first blades are parallel and spaced apart by a to form several air channels. The second blades overlap the inner side of the louver and are spaced apart by b to form an air vent. The air vent is located at the upper end of the air channels. The mesh section is located on the outer side of the louver or inside the air channels. The mesh section has several through holes, each through hole being cylindrical in shape. The height of each through hole is 0.5~2.5mm, and the diameter is 0.5~2.5mm. Liquid is injected from all directions outside the louver into the through holes. The liquid is constrained by the cylindrical shape of the through holes and changes direction, exiting along the axis of the cylinder. All the liquid is blocked by the blades within the air channels and then flows out through the through holes from the outer side of the louver. The air vent is located outside the area covered by the axial direction, thereby preventing the injected liquid from passing through the air vent.

[0007] Compared with existing technologies, the beneficial effects of this utility model of a louver are as follows: 1. The dustproof rating can reach IP3X~IP4X, and the waterproof rating can reach IPX4~IPX6. While ensuring good ventilation, the protection level is significantly improved compared to existing technologies. Adding a dustproof filter layer on the inner side further enhances the dustproof rating. 2. The mesh plate is on the outside of the louver, making it easy to clean dust accumulation from the outside without opening the door, thus facilitating maintenance. 3. Compared with existing technologies, the air duct is simpler and more unobstructed, which helps reduce wind resistance. 4. The structure is simplified; it can be processed from steel plates, and the blades do not need to be made of aluminum alloy profiles, reducing costs.

[0008] Preferably, the height of the through hole is 0.5~1mm and the diameter is 0.8~1mm.

[0009] Preferably, the through hole has a height of 1.5~2mm and a diameter of 2~2.5mm.

[0010] Preferably, the lower edge of the mesh portion abuts against the outer upper side of the first piece, and the upper edge of the mesh portion abuts against the inner lower side of the first piece.

[0011] Preferably, the mesh portion overlaps with the outer surface of the louver.

[0012] Preferably, the cross-section of the mesh portion has a continuous wavy tortuosity, and each tortuosity portion abuts against each of the first pieces.

[0013] Preferably, it includes a frame that connects and fixes the blade portion and the mesh portion.

[0014] A housing comprising the louvers described in any of the preceding claims, the louvers being mounted on the outer wall of the housing.

[0015] A prefabricated power station includes the aforementioned enclosure and electrical or electronic equipment built into the enclosure.

[0016] A container house includes the aforementioned container body, and electrical equipment or furniture built into the container body. Attached Figure Description

[0021] To explain in detail the technical content, structural features, implementation principle, and achieved purpose and effect of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] like Figure 1 , Figure 2 As shown, this utility model discloses a louver 30 according to a first embodiment, including a blade section 1, a mesh section 2, and a frame (not shown). The blade section 1 is located on the inner side of the louver 30 and includes several blades 1 arranged vertically side by side. Each blade 1 includes intersecting first blades 5 and second blades 6. The first blades 5 are parallel and spaced apart by a to form several air ducts 3. The second blades 6 overlap the inner side of the louver 30 and are spaced apart by b to form air vents 4. The air vents 4 are located at the upper end of the air ducts 3. The mesh section 2 is located on the outer side of the louver 30 or inside the air ducts 3. The mesh section 2 has several through holes 8 distributed on it. The through holes 8 are cylindrical in shape, with a height of 0.5~2.5mm and a diameter of 0.5mm. ~2.5mm, liquid 9 is injected from all directions outside the louver 30 towards the through hole 8. Constrained by the cylindrical shape of the through hole 8, the liquid 9 changes direction and is ejected along the axis 22 of the cylinder to form liquid 10. All liquid 10 is blocked by the blades 1 within the air duct 3, changing direction to form liquid 11. Liquid 11 then flows out through the through hole 8 to the outside of the louver 30. The air outlet 4 is located outside the coverage area along the axis 22, thus preventing the injected liquid 10 from passing through the air outlet 4. Airflow 12 passes through the through hole 8 of the mesh portion 2 to form airflow 13, which flows along the air duct 3 and through the air outlet 4. Alternatively, airflow 13 passes through the air outlet 4, flows along the air duct 3, passes through the through hole 8 of the mesh portion 2, and then forms airflow 12. The mesh portion 2 overlaps with the outer surface of the louver 30.

[0023] like Figure 2As shown in the cross-sectional view of the perforated plate 2 of this utility model, the height 20 of the through hole 8 is 0.5~1mm and the diameter 21 is 0.8~1mm, which can achieve IP4X protection. Preferably, the height 20 is 0.7mm and the diameter 21 is 1mm. Liquid is injected into the through hole 8 from all directions, with the injection angle 23 ranging from 0 to 180°. The liquid is constrained by the through hole 8 and exits along the axis 22 perpendicular to the perforated plate 2. The prior art utilizes the function of perforated plates to prevent objects larger than a set diameter from passing through, such as the IP4X standard, which prevents objects with a diameter greater than 1mm from passing through. When manufacturing perforated plates, as long as the material and thickness of the plate meet the strength requirements, for cost considerations, the prior art prefers thinner plates (0.3 or 0.4mm thick) or woven wire mesh. Experiments revealed that when liquid passes through small holes in a column, if the height of the hole (equivalent to the thickness of the plate) is close to the diameter of the hole, the liquid (usually water) enters the hole at an angle of 0-180°, and the liquid exits along the axis. However, with thinner mesh plates, the liquid exits along the incident direction. Utilizing the axial ejection effect, the blades do not need to construct complex labyrinthine air ducts; they only need to block the ejected liquid within the axial coverage area to prevent liquid from passing through the louvers.

[0024] As another option, the perforated plate 2 is made of 1.5mm thick material, and the through holes 8 are 2.5mm in diameter, which can achieve IP34 or IP35 protection.

[0025] Compared with existing technologies, this utility model's louver achieves a dustproof rating of IP3X~IP4X and a waterproof rating of IPX4~IPX6. While ensuring good ventilation, the protection level is significantly improved compared to existing technologies. Adding a dustproof filter layer on the inner side further enhances the dustproof rating. The perforated plate 2 is located on the outer side of the louver 30, allowing for easy cleaning of dust accumulation from the outside without opening the door, simplifying maintenance. Compared to existing labyrinth duct technology, the duct 3 is simpler and more unobstructed, reducing wind resistance. The simplified structure allows for the use of steel plates, eliminating the need for aluminum alloy blades and reducing costs.

[0026] like Figure 3 As shown, in the second embodiment of this utility model, the lower edge of the mesh portion 2 abuts against the outer upper side of the first piece 5, and the upper edge of the mesh portion 2 abuts against the inner lower side of the first piece 5. The structural characteristics of the mesh portion 2 are described in the attached diagram. Figure 2 The width of the mesh portion 2 is about 50% greater than that of the first embodiment of this utility model, which can provide a larger effective ventilation area while meeting IP protection standards. As a variation of the second embodiment, the cross-section of the mesh portion 2 is continuously wavy and tortuous, and each tortuous portion abuts against each first piece 5, which can further increase the area of ​​the mesh portion 2.

[0027] The above embodiment includes a frame (not shown), which connects and fixes the blade portion 1 and the mesh portion 2.

[0028] like Figure 4 As shown, a box-like enclosure includes louvers 30, which are installed on the outer wall of a housing 31. The enclosure houses internal electrical or electronic equipment 32, constituting a box-type power station. The enclosure also houses internal electrical equipment or furniture 32, constituting a box-type house.

[0029] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
