DETAILED DESCRIPTION

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0028] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0029] Example 1

[0030] like Figure 1 , Figure 2 A heat dissipation structure of a high and low voltage distribution cabinet comprises a distribution cabinet side panel 10 and a heat dissipation port 20. The heat dissipation port 20 is provided in the distribution cabinet side panel 10 for heat dissipation.

[0031] The side panel 10 of the distribution cabinet includes a cover plate 11 and a cover plate 12, which are slidably connected to each other. The cover plate 11 and the cover plate 12 are both provided with heat dissipation openings 20. When the cover plate 11 and the cover plate 12 slide relatively, the heat dissipation openings 20 located on the cover plate 11 and the cover plate 12 are aligned or staggered to achieve the purpose of adjusting the heat dissipation area.

[0032] Preferably, when the cover plate 1 11 and the cover plate 2 12 completely slide to the end of the movable path, the heat dissipation openings 20 on the cover plate 1 11 and the cover plate 2 12 are completely aligned, and this is the moment when the heat dissipation area is the largest; correspondingly, when the cover plate 1 11 and the cover plate 2 12 are in the initial state, the heat dissipation openings 20 on the cover plate 1 11 and the cover plate 2 12 are only generally aligned, and the heat dissipation area is half of the heat dissipation openings 20.

[0033] It should be noted that the cover plate 11 is fixed to the bottom plate of the distribution cabinet, the cover plate 2 12 is fixed to the top plate, the cover plate 11 and the cover plate 2 12 are controlled by a hydraulic cylinder, the cylinder seat of the hydraulic cylinder is fixed on the bottom plate, the telescopic rod of the hydraulic cylinder is fixedly connected to the cover plate 2 12, and the specific structure and operation logic of the hydraulic cylinder are existing technologies, so they are not repeated here.

[0034] The advantage of this design is that when the load of electrical equipment in the distribution cabinet is small, in addition to ensuring normal heat dissipation requirements, the heat dissipation area can be appropriately reduced to reduce the volume of dust entering the distribution cabinet with the airflow.

[0035] Example 2

[0036] like Figure 1 , Figure 3 , Figure 4 The side panel 10 of the distribution cabinet is composed of a number of slidingly connected single plates 13, wherein some of the single plates 13 arranged at intervals are fixedly connected to the bottom plate of the distribution cabinet, and another part of the single plates 13 are fixedly connected to the top plate of the distribution cabinet, and the single plates 13 connected to the bottom plate and the single plates 13 connected to the top plate are staggered.

[0037] For the convenience of description, the single board 13 connected to the bottom panel is defined as a lower single board 13 , and the single board 13 connected to the top panel is defined as an upper single board 13 .

[0038] The upper single plate 13 is driven by a hydraulic cylinder, a cylinder seat of the hydraulic cylinder is fixed on the bottom plate, and a telescopic rod of the hydraulic cylinder is fixed to the upper single plate 13. The structure and control logic of the hydraulic cylinder are prior art, so they are not described in detail.

[0039] The heat dissipation port 20 includes a single port 21 and an opening and closing port 22. A plurality of single ports 21 are provided on the upper and lower single plates 13. When the upper and lower single plates 13 slide relative to each other, the space formed between the bottom plate and the top plate is the opening and closing port 22. As the displacement of the upper and lower single plates 13 increases, the opening area of ​​the opening and closing port 22 gradually increases to achieve the effect of adjustable heat dissipation area.

[0040] Preferably, a grid is laid on the opening 22 .

[0041] Preferably, the grid is made of elastic material and can be curled. The grid located at the bottom is fixed to the bottom of the upper single board 13, and the grid located at the top is fixed to the lower single board 13. When the upper and lower single boards 13 are separated, the grid can self-adjust according to the expansion space size of the opening and closing mouth 22.

[0042] Example 3

[0043] like Figure 4-Figure 8 On the basis of Example 2, a cooling pipe laying system 30 is also designed, which is matched with the technical solution of Example 2 to further improve the heat dissipation effect of the entire distribution cabinet.

[0044] The single plate 13 is a sheet metal part with two ends bent, and the single opening 21 is formed by punching the sheet metal part.

[0045] In one case of the present embodiment, the cooling pipe laying system 30 includes a crossbeam 31, a clamp 32 and a pipe 33. The crossbeam 31 is connected to the two ends of the heat dissipation port 20 in a damping sliding manner. The crossbeam 31 is rotatably connected with the clamp 32, and the clamp 32 is snap-connected with the pipe 33. The clamp 32 is deformable, and the pipe 33 is inserted into the clamp by squeezing the pipe 33 into the clamp. When disassembly is required, the pipe 33 can be pulled out.

[0046] The clamp 32 can rotate relative to the crossbeam 31, so it can drive the pipe 33 to rotate. A cooling pipe laying system 30 is installed in each single board 13. By rotating the cooling pipe laying system 30, the following can be achieved: Figure 5 The coolant pipe layout shown in L1.

[0047] Because the position between the upper and lower single plates 13 is adjustable, the flexibility of the cooling pipe laying system 30 in path design is improved on the basis that the pipe 33 is rotatable.

[0048] It should be known that both ends of the pipe 33 are provided with threads. When connecting two pipes 33, another pipe joint with threads is used for connection. After several pipes 33 located on a single board 13 are connected, it is necessary to additionally connect the corresponding pipes 33 and the external pipe for providing coolant.

[0049] like Figure 6 As shown in L2 in FIG. 1 , the pipeline can also be designed using a three-way joint.

[0050] In another situation of this embodiment, the cooling pipe laying system 30 includes a crossbeam 31, a clamp 32, a pipe 33 and a slider 34. The crossbeam 31 is connected to the two ends of the heat dissipation port 20 in a damping sliding manner. A slide groove is provided on the crossbeam 31, and a slider 34 is slidably connected in the slide groove. The clamp 32 is rotatably connected to the slider 34, and the pipe 33 is clamped and connected to the clamp 32. The clamp 32 is deformable, and the pipe 33 is squeezed into the clamp 32 to allow the pipe 33 to be clamped into the pipe 33. When disassembly is required, the pipe 33 can be pulled out.

[0051] The cooling pipe laying system 30 can be designed to be dense at the bottom and sparse at the top so as to improve the heat dissipation efficiency for the bottom environment. Vice versa, the cooling pipe laying system 30 can be reasonably designed to flexibly adjust the local efficient heat dissipation capacity.

[0052] Working principle of the present invention:

[0053] The present invention improves the heat dissipation efficiency of the power distribution cabinet under high load by designing a structure with adjustable heat dissipation area, and at the same time, it is matched with a cooling pipe laying system 30 with freely adjustable paths to combine air cooling and water cooling to further improve the heat dissipation efficiency.
