Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and particularly relates to a gas chamber housing structure of an inflatable switch cabinet that is convenient for heat dissipation. Background Art

[0002] Medium-voltage gas-insulated switch cabinets have been practically applied in many power projects in recent years due to their characteristics of miniaturization, maintenance-free, and immunity to environmental influences. As the main switch-bearing compartment and insulation compartment, the gas chamber is one of the core components of medium-voltage gas-insulated switch cabinets. The main circuit components are all concentrated and enclosed in the gas chamber. Therefore, when the medium-voltage gas-insulated switch cabinet operates, the energy in the gas chamber is too concentrated, and the concentrated setting of the main circuit components hinders heat dissipation, resulting in too high a temperature inside the gas chamber, thus damaging the insulation structure, affecting the safe and stable operation of the equipment, and even causing serious economic losses and social impacts.

[0003] In the prior art, generally, a fan is used for heat dissipation. However, due to the closed space inside the gas chamber, the air flow flows chaotically inside the gas chamber, and the heat cannot be effectively dissipated. Summary of the Invention

[0004] The purpose of the present invention is to provide a gas chamber housing structure of an inflatable switch cabinet with good heat dissipation effect in view of the deficiencies of the prior art.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

It is a cuboid housing, including a top plate, a bottom plate, and four side plates.

The left side plate and the right side plate are provided with a corrugated structure, and the left and right ends of the top plate and the left and right ends of the bottom plate are both provided with a serrated structure matching the corrugated structure.

[0008] In the above technical solution, strengthening wing plates are spaced between two opposite side plates, and the strengthening wing plates are installed on the lower surface of the top plate and the upper surface of the bottom plate.

[0009] In the above technical solution, the strengthening wing plate is a long strip plate with two wide opposite faces, and the wide face of the strengthening wing plate is perpendicular to the bottom plate and the top plate.

[0010] In the above technical solution, the strengthening wing plate is perpendicular to the left side plate and the right side plate.

[0011] In the above technical solution, reinforcing wing plates are installed at intervals on the upper surface of the top plate, and the reinforcing wing plates on the upper surface of the top plate and the reinforcing wing plates on the lower surface of the top plate are arranged in a cross manner.

[0012] In the above technical solution, the reinforcing wing plates on the upper surface of the top plate and the reinforcing wing plates on the lower surface of the top plate are arranged vertically.

[0013] In the above technical solution, through holes for installing electrical components are provided on the front side plate, the rear side plate, the top plate and the bottom plate.

[0016] Advantages of the present invention:

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] An inflatable switchgear chamber for facilitating heat dissipation in this embodiment is a cuboid shell, including a top plate 1, a bottom plate 2 and four side plates 3. In order to improve the heat dissipation effect of the chamber, at least two opposite side plates 3 in this embodiment are set as corrugated structures, and the corrugated protruding parts are perpendicular to the top plate 1 and the bottom plate 2. At the same time, the ends of the top plate 1 and the bottom plate 2 connected to the corrugated side plates 3 are set as serrated structures matching the corrugated structure. In this way, multiple independent air ducts can be formed at the corrugated side plates 3, so that the airflow generated by the operation of the fan can flow regularly in the chamber, thereby effectively dissipating heat.

[0026] The chamber structure of this embodiment is as Figure 1 shown. The side plates 3 include a left side plate 31, a right side plate 32, a front side plate 33 and a rear side plate 34. The left side plate 31 and the right side plate 32 are set as corrugated structures with the protruding parts perpendicular to the top plate 1 and the bottom plate 2. The left and right ends of the top plate 1 and the left and right ends of the bottom plate 2 are both set as serrated structures matching the corrugated structure, so as to form multiple independent air ducts at the left side plate 31 and the right side plate 32 for facilitating heat dissipation.

[0027] The corrugated side plates of this embodiment, as Figure 2 and Figure 3 shown, the width of each protruding part is set as L, the height of each protruding part is set as H, the angle between the protruding part and the inclined part is set as α, and the bending radius is set as R. The smaller L is, the more the number of independent air ducts formed at the side plates, and the better the heat dissipation effect; the larger H is, the larger the heat dissipation area increased by the corrugated side plate 3 compared with the flat plate, and the better the heat dissipation effect; the closer α is to 90°, the stronger the gas fluidity in the air duct, and the better the heat dissipation effect. Considering both economy and functionality, in this embodiment, L of the corrugated side plate 3 is set as 30 mm, H is set as 50 mm, α is set as 120°, and R is set as 8 mm. At this time, the heat dissipation area of the corrugated side plate 3 is 145% of the heat dissipation area of the flat plate, so that the heat dissipation effect can be greatly improved.

[0028] In order to improve the anti-deformation ability of the chamber, in this embodiment, inner strengthening wing plates 51 are spaced between two opposite side plates 3, and the inner strengthening wing plates 51 are installed on the lower surface of the top plate 1 and the upper surface of the bottom plate 2, as Figure 4As shown, the inner reinforcing wing plate 51 is a long strip plate with two wide opposite faces, and the wide face of the inner reinforcing wing plate 51 is perpendicular to the bottom plate 2 and the top plate 1. Such a design effect not only improves the anti-deformation ability of the air chamber, but also has a better heat dissipation effect compared with the setting method of forming a heat preservation interlayer with the wide face of the inner reinforcing wing plate 51 parallel to the bottom plate 2 and the top plate 1.

[0029] Furthermore, the inner reinforcing wing plate 51 of this embodiment is perpendicular to the left side plate 31 and the right side plate 32, so that a plurality of independent air ducts can be formed between the left side plate 31 and the right side plate 32, and combined with the plurality of independent air ducts at the left side plate 31 and the right side plate 32, a plurality of complete air duct circuits can be formed, making the heat dissipation effect better.

[0030] As Figure 1 shown, the outer reinforcing wing plate 52 is installed at intervals on the upper surface of the top plate 1, and the outer reinforcing wing 52 is arranged crosswise with the inner reinforcing wing plate 51, and their common action is beneficial to further improving the anti-deformation ability of the top plate 1. Furthermore, referring to Figure 1 and Figure 4 , the outer reinforcing wing plate 52 and the inner reinforcing wing plate 51 are arranged perpendicular to each other, so that the anti-deformation effect reaches the best.

[0031] For the air chamber housing of this embodiment, the left side plate 31, the right side plate 32, the front side plate 33, the rear side plate 34, the top plate 1, the bottom plate 2, the outer reinforcing wing plate 52 and the inner reinforcing wing plate 51 are all made of high-strength stainless steel plates. In this way, whether it is to perform corrugated bending on the left side plate 31 and the right side plate 32, or to open through holes 4 for installing electrical components on the front side plate 33, the rear side plate 34, the top plate 1 and the bottom plate 2, no deformation will occur due to the increase of the internal pressure of the air chamber during long-term use.

[0032] In addition, a lifting plate 6 is also installed on the upper surface of the top plate 1 to facilitate the handling, lifting or other movement of the air chamber.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
