Description

Technical Field

[0001] This utility model relates to the field of enclosure ventilation and heat dissipation technology, and in particular to a base 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 power stations and prefabricated houses are typically equipped with louvers on the enclosure. However, to achieve IP34 or higher protection levels, existing louvers use a labyrinthine air duct with several blades, resulting in a complex structure, high wind resistance, and high cost. Utility Model Content

[0005] The purpose of this utility model is to provide a base louver, a box body, 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 base louver, characterized in that it includes several blades spliced ​​and fixed in a "W" shape within a frame. The blades are distributed with several through holes, each through hole being cylindrical in shape, with a height of 0.5~2.5mm and a diameter of 0.5~2.5mm. Liquid is ejected from below the base louver towards the through holes. The liquid is constrained by the cylindrical shape of the through holes, changing direction and ejecting along the axis of the cylinder. The liquid is ejected towards adjacent blades and falls due to gravity, passing through the through holes again and exiting the base louver.

[0007] Compared with existing technologies, the beneficial effects of this utility model's base 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. Compared with existing technologies, the air duct is larger, simpler, and more unobstructed, which helps reduce wind resistance. Equipment inside the enclosure, such as transformers, achieves better heat dissipation, reducing forced cooling by fans, lowering the failure rate, and reducing operating energy consumption.

[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 device includes several fixing plates, each fixing plate having a V-shaped notch corresponding to the blade to fix the blade.

[0011] A housing includes a base louver as described in any of the preceding claims, the base louver being mounted on the base of the housing.

[0012] A prefabricated power station includes the aforementioned enclosure and electrical or electronic equipment built into the enclosure.

[0013] A container house includes the aforementioned container body, and electrical equipment or furniture built into the container body. Attached Figure Description

[0017] Figure 4 This is a schematic diagram of the structure of the prefabricated box-type power station or box-type house of this utility model. Detailed Implementation

[0018] 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.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a base louver 10, which includes several blades 1 spliced ​​and fixed in a "W" shape inside the frame 2. Several through holes 4 are distributed on the blades 1. The through holes 4 are cylindrical in shape. The height 3 (equivalent to the plate thickness) of the through holes is 1 mm and the diameter is 1 mm. Liquid is shot from the bottom of the base louver 10 in various directions 5 towards the through holes 4. The liquid is constrained by the cylindrical shape of the through holes 4 and changes direction to be shot out along the axis 6 of the cylinder. The liquid is shot towards the adjacent blades 1 and falls down under gravity, and then passes through the through holes 4 again to be discharged outside the base louver.

[0020] like Figure 2As shown in the cross-sectional view of the blade 1 of this utility model, the height 3 of the through hole 4 is 1mm and the diameter is 1mm, which can achieve IP4X protection. Liquid is injected into the through hole 4 from various directions, with an injection angle 23 ranging from 0 to 180°. The liquid is constrained by the through hole 4 and exits along the axis 6 perpendicular to the blade 1. Existing technology 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, existing technology prefers thinner plates (0.3 or 0.4mm thick) or woven wire mesh. Through experiments, it was found that when liquid passes through the small hole of the column, when the height of the small hole (equivalent to the thickness of the plate) is close to the diameter of the small hole, the angle of liquid (usually water) entering the small hole is 0 to 180°, and the liquid exits along the axis; while thinner perforated plates exit along the incident direction. By utilizing the axial ejection effect, the blades do not need to be constructed with complex labyrinth air ducts. They only need to block the ejected liquid within the axial coverage area to prevent the liquid from passing through the louvers.

[0021] Compared with the prior art, the dustproof rating of the base louver of this utility model can reach IP4X and the waterproof rating can reach IPX4~IPX6. Under the condition of good ventilation of the base louver, the protection level is significantly improved compared with the prior art. Adding a dustproof filter layer on the inside can further improve the dustproof rating.

[0022] like Figure 3 As shown in the schematic diagram of another base louver structure of this utility model, it includes several upper fixing plates 3 and lower fixing plates 4, with V-shaped slots opened on the upper fixing plates 3 and lower fixing plates 4 to fix the blades 1.

[0023] like Figure 4 As shown, a box-type enclosure includes a base louver 10, which is mounted on a base 13 of a housing 11. The enclosure 11 houses internal electrical or electronic equipment 12, constituting a box-type power station. The enclosure 11 also houses internal electrical equipment or furniture 12, constituting a box-type house.

[0024] 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.
