Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for power distribution cabinets, specifically relating to a heat dissipation cabinet side sealing structure and integrated cabinet assembly. Background Technology

[0002] With the widespread use of high-current medium-voltage power distribution switchgear, the electrical load is constantly increasing, and the heat generated by the power distribution switchgear is also increasing significantly. Taking multiple measures to dissipate heat has become a major problem for power maintenance personnel.

[0003] Most current heat dissipation cabinets are designed with a cooling fan and two heat dissipation channels at the top of the original cabinet to improve heat dissipation and reduce heat dissipation time. In addition to the following heat dissipation measures, to increase the heat dissipation power of heat convection and heat radiation, it is necessary to increase the heat dissipation area of ​​the distribution cabinet. Since other cabinets are arranged on both sides of the distribution cabinet, the area of ​​the two sides is always ignored when calculating the heat dissipation area of ​​the distribution cabinet. This leads to the assumption that only the front, back and top of the cabinet dissipate heat. However, according to the structural characteristics of the distribution cabinet, it is almost impossible to increase the area of ​​these three sides on the existing basis.

[0004] Therefore, increasing the heat dissipation area and improving the heat dissipation effect is a major challenge. Utility Model Content

[0005] The purpose of this utility model is to provide a heat dissipation cabinet side sealing structure and integrated cabinet assembly. The side sealing structure is designed based on the side wall of the cabinet, so that the side wall contributes to heat dissipation, thereby increasing the heat dissipation area and heat dissipation effect; it has a wide range of applications.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose a heat dissipation cabinet side sealing structure. The side sealing structure includes a fixed support point and an end plate. The fixed support point is set between two adjacent side walls of two parallel cabinets to form a gap between the two adjacent side walls. The two end plates are respectively embedded and sealed to the front and rear sides of the gap, so that the airflow in the gap flows upward or downward along the gap.

[0007] Preferably, the fixed support point is a bracket structure, such as a "C" type bracket. The "C" type bracket creates a gap between the two cabinets, and the front and back sides of the gap are sealed and filled by end plates to maintain the consistency of appearance. At the same time, it increases the additional heat dissipation space of the cabinet and improves the heat dissipation effect.

[0008] Specifically, two fixed support points are provided in the gap, and the two fixed support points are respectively located on the front and rear sides of the gap; the two ends of the fixed support points abut against and are fixed to the two side walls respectively, and the end plate is fixed to the outer side of the fixed support point, and the exposed surface of the end plate is flush with the outer surface of the cabinet.

[0009] It is feasible to use insulators as fixed support points and insulators on two adjacent side walls, symmetrically distributed. The gap between the two cabinets is created by the insulators abutting each other. The front and back sides of the gap are sealed and filled by end plates to maintain the consistency of appearance, while increasing the cabinet's additional heat dissipation space and improving the heat dissipation effect.

[0010] For example, the side sealing structure includes multiple fixed support points and two end plates. The multiple fixed support points are symmetrically distributed on two adjacent side walls of two parallel cabinets. The fixed support points on the two side walls abut against each other, so that a gap is formed between the two adjacent side walls. The two end plates are respectively embedded and sealed to the front and rear sides of the gap, so that the airflow in the gap flows upward or downward along the gap.

[0011] Specifically, the gap includes multiple fixed support points, which are symmetrically distributed on two adjacent side walls, and the fixed support points on the two side walls abut against each other.

[0012] Furthermore, a sealing plate is provided on the side of the end plate facing the interior of the gap, and two corresponding fixing points on two adjacent side walls abut against the two sides of the sealing plate; the sealing plate is fixedly connected to the fixing points, embedding and fixing the end plate in the gap, and the exposed surface of the end plate is flush with the outer surface of the cabinet on the corresponding side; the sealing plate is parallel to the two adjacent side walls.

[0013] The side wall may or may not have ventilation holes, and the sealing plate may or may not have ventilation holes.

[0014] Furthermore, a sealing plate is provided on the side of each of the two end plates facing the interior of the gap, and a fixing point is provided at each of the four corners of the two side walls. The two pairs of fixing points on the front side are used to fix the sealing plate extending from the end plate on the front side; the two pairs of fixing points on the rear side are used to fix the sealing plate extending from the end plate on the rear side.

[0015] Furthermore, a sealing plate is provided inside the gap of the two end plates, and a fixed support point is provided at each of the four corners of the two side walls. The four pairs of fixed support points fix the sealing plate flatly to the outside of the side wall.

[0016] The two adjacent sidewalls are parallel, and the distance between the sealing plate and the two sidewalls may be the same or different.

[0017] When they are not the same, a fixed support point is provided at each of the four corners of the side wall, and the four fixed support points fix the sealing plate flat to the outside of the side wall.

[0018] At the same time, a fixed support point is provided at each of the four corners of the two adjacent side walls, and the four pairs of fixed support points fix the sealing plate flat in the middle of the two side walls.

[0019] Preferably, the sealing plate is located in the middle of the two side walls and is spaced the same from the two side walls.

[0020] Furthermore, the end plate is vertically sealed to the side end of the sealing plate, the end plate is embedded between two adjacent side walls, and the outer surface of the end plate is flush with the front or rear surface of the two adjacent cabinets.

[0021] The sealing plate is provided with end plates at both the front and rear ends, and the two end plates respectively close the front and rear sides of the gap; the fixing point is located between the two end plates, i.e., on the inner side.

[0022] Furthermore, a clip is provided at the middle of the inner side of the end plate, and a slot is provided at the side end of the sealing plate. The clip is snapped into the slot, and the outer surface of the end plate is flush with the front or rear surface of the two adjacent cabinets.

[0023] Furthermore, the end plate has inwardly abutting bodies on both sides, and the clip is located between the abutting bodies on both sides, with the abutting bodies on both sides abutting against the two adjacent side walls respectively.

[0024] Furthermore, the end plate is located within the gap, and its two ends abut against and are fixed to the two side walls respectively.

[0025] This utility model also proposes an integrated cabinet group, which consists of multiple cabinets and multiple side sealing structures as described above. The multiple cabinets are placed side by side, and a side sealing structure is provided between two adjacent cabinets.

[0026] Furthermore, the multiple cabinets included in the integrated cabinet group have the same external dimensions, and the multiple cabinets may be of the same or different types.

[0027] Furthermore, ventilation holes are provided on the sealing plate, and multiple ventilation holes are arranged in an array on the sealing plate to form a ventilation hole array. The ventilation hole array includes a first zone, a second zone, and a third zone from top to bottom. The first zone is at the same height as the first equipment layer inside the cabinet, the second zone is at the same height as the second equipment layer inside the cabinet, and the third zone is at the same height as the third equipment layer inside the cabinet.

[0028] The beneficial effects of this utility model are as follows:

[0029] This utility model proposes a heat dissipation cabinet side sealing structure and integrated cabinet assembly. A new side sealing structure is designed between the side walls of the cabinet to increase the heat dissipation area of ​​the cabinet. The side sealing structure is still assembled based on the side walls of the cabinet. A gap that allows air to flow is formed between the two cabinets based on the side sealing structure, so that the side walls of the cabinet contribute to heat dissipation and improve the heat dissipation area and heat dissipation effect.

[0030] The side sealing structure of this application can be applied to high-voltage distribution cabinets, medium-voltage distribution cabinets, and low-voltage distribution cabinets. When applied to different types of distribution cabinets, the side sealing structure itself has also been adjusted accordingly to meet actual needs.

[0031] The sealing plates and fixed supports in the side sealing structure create a gap between the two cabinets after assembly. The end plates in the side sealing structure then seal the front and back sides of the gap between the two cabinets, leaving the top and bottom unsealed, allowing air to flow upwards or downwards; generally, the airflow is upwards.

[0032] Multiple cabinets can be placed side by side, and adjacent cabinets can be assembled through a side sealing structure to connect multiple cabinets into a whole, while maintaining the relative independence of each cabinet, so that the installation and operation of the equipment are not affected.

[0033] It can not only increase the heat dissipation area and effect of a single cabinet, but also combine multiple cabinets into a heat dissipation body. The ventilation holes on the cover plate can generate air convection between the two cabinets on both sides of the cover plate, with a large air circulation range, thus optimizing the overall heat dissipation effect.

[0046] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0047] This utility model embodiment provides a heat-dissipating cabinet side sealing structure. Please refer to [link / reference]. Figures 1-7 The side sealing structure 1 includes a fixed support point 2 and an end plate 12. The fixed support point 2 is set between two adjacent side walls 31 of the two parallel cabinets 3, so that a gap is formed between the two adjacent side walls 31. The two end plates 12 are respectively embedded and sealed to the front and rear sides of the gap, so that the airflow in the gap flows upward or downward along the gap.

[0048] In this application, the side sealing structure 1 is applied between two parallel cabinets 3. The parallel spacing is affected by the height of the fixed support point 2. The side sealing structure 1 is fixedly installed based on the two adjacent side walls 31 of the two parallel cabinets 3. Figure 1 , Figure 3 , Figure 5As shown, a fixed support point 2 is provided on the side wall 31 of the cabinet 3. A conventional sealing plate can be mounted on the side wall 31 to maintain the airtightness. The side sealing structure 1 in this application increases the gap between the two cabinets, forming a gap, and the heat dissipation effect is improved by using this gap.

[0049] Preferably, the fixed support point 2 is a bracket structure, such as a "C" type bracket; the "C" type bracket creates a gap between the two cabinets 3, and then the front and back sides of the gap are sealed and filled by the end plate 12 to maintain the consistency of appearance, while increasing the additional heat dissipation space of the cabinet 3 and improving the heat dissipation effect.

[0050] For details, please refer to Figure 1 , Figure 2 Two fixed support points 2 are provided in the gap, and the two fixed support points 2 are respectively located on the front and rear sides of the gap; the two ends of the fixed support points 2 abut against and are fixed to the two side walls 311 respectively, and the end plate 12 is fixed to the outer side of the fixed support points 2, and the exposed surface of the end plate 12 is flush with the outer surface of the cabinet 3.

[0051] In one specific embodiment, the support structure can be a sealing strip support with a "C" shaped cross-section, that is, it includes an end panel and two bent plates that are perpendicular to each other into the gap, with a bent plate on each side of the end panel.

[0052] The bracket structure is embedded in the gap, with the end panel facing the outside of the gap. Two brackets can be set at the front and back of the gap respectively. The bent plate on the left is fixed to the side wall 31 of the left cabinet 3 by bolts, and the bent plate on the right is fixed to the side wall 31 of the right cabinet 3 by bolts. The end panel is a certain distance away from the outer surface of the cabinet 3, thus forming the accommodating space of the end plate 12. The end plate 12 is fitted into and filled into the accommodating space, so that the exposed surface of the end plate 12 is flush with the outer surface of the cabinet 3.

[0053] The end plate 12 can be fixedly connected to the support structure using bolts. When the end plate 12 is fixed to the end panel using bolts, the bolts can be located in the middle of the end plate 12. Figure 2 As shown in the image; they can also be fastened together by other detachable fixing methods, such as clips.

[0054] Understandably, the end plate 12 can be relatively thin, while the fixed support 2 should have sufficient strength to ensure the structural stability between the two cabinets 3 and to stabilize the relative position of the two cabinets 3.

[0055] Corresponding through holes can be made on the bending plate based on the existing screw holes on the side wall 31, and fixed installation can be carried out based on the existing screw holes on the cabinet 3. The dimensions of the bracket structure and the end plate 12 can be adjusted according to the dimensions between the existing screw holes and the cabinet frame, so that the side sealing structure 1 can be installed and fixed based on the existing screw holes on the cabinet 3 without the need to make additional holes.

[0056] It can be understood that the support structure can also have a bent plate on only one side, which is fixed only to the side wall 31 on one side. The cabinet 3 on the other side is attached to it by the mounting structure of the base. The two cabinets 3 are not substantially connected by the fixed support point 2. It is more convenient to disassemble and replace a single cabinet 3. At the same time, it does not affect the formation of the gap. The airflow in the gap can still flow upward or downward along the gap. If there is a need for sealing, a sealing strip can be sandwiched between the end plate 12 and the end plate of the fixed support point 2. The sealing strip can be placed on the cabinet 3 on one side and abut against the side wall 31 of the cabinet 3 on that side to solve the sealing problem.

[0057] It is feasible to use a cylindrical insulator as the fixed support point 2, and insulators are installed on the two adjacent side walls 31 in a symmetrical distribution. The gap between the two cabinets 3 is created by the insulators abutting each other. The front and back sides of the gap are sealed and filled by the end plate 12 to maintain the consistency of appearance. At the same time, it increases the heat dissipation space of the cabinet 3 and improves the heat dissipation effect.

[0058] The end plate 12 can be fixedly installed based on the insulator-type fixed support point 2. For specific solutions, please refer to the following embodiments:

[0059] Multiple (insulator) fixing points 2 of the same height can be set on the side wall of the cabinet 3. The fixing points 2 are all fixed perpendicular to the side wall 31. The fixing points 2 on the two side walls 31 are symmetrically arranged. The two cabinets 3 are installed at the same height. The fixing points 2 on the two side walls 31 abut against each other one by one, so that the distance between the two cabinets 3 is stable.

[0060] The gaps between the cabinet bodies 3 are sealed by end plates 12, filling the large gaps caused by the presence of fixed support points 2. Preferably, the exposed surface of the end plate 12 is flush with the outer surface of the cabinet body 3, consistent with the conventional close-fitting appearance. For example, the exposed surface of the end plate 12 located on the front side of the gap is flush with the front surface of the cabinet body 3, and the exposed surface of the end plate 12 located on the rear side of the gap is flush with the rear surface of the cabinet body 3.

[0061] In this application, the distance between the two cabinets is positively correlated with the height of the fixed support 2. The fixed support 2 between the side walls 31 ensures the relative stability of the distance between the cabinets. A gap is formed between the two side walls 31. For the cabinet 3, these gaps not only pose a risk of pinching hands, but also cause inconvenience during installation. If there are gaps on the side walls 31, there is also a risk of external intrusion.

[0062] Therefore, this application closes the front and rear sides of the gap with the end plate 12, forming the same structural effect as when the cabinet 3 is placed close together. At the same time, it retains the heat dissipation effect of the gap, allowing airflow to flow upward or downward. With the help of external heat dissipation equipment, it can effectively improve the heat dissipation effect of the cabinet.

[0063] In this application, the end plate 12 can be fixed based on the fixed support point 2, fixing the end plate 12 between two opposing fixed support points 2, such as... Figure 3 , Figure 5 As shown in the figure. Of course, it can also be fixed based on the side wall 31. The two ends of the end plate 12 can be abutted and fixed to the two side walls 31 respectively. The fixing method can be snap-fit, adhesive or other forms.

[0064] When fixed based on fixed fulcrum 2, a sealing plate 11 can be installed on the inner side of end plate 12. End plate 12 is a long strip-shaped structure that extends from the top to the bottom of cabinet 3 within the gap. The sealing plate 11 is parallel to the side wall 31 and is vertically fixed to end plate 12. The top view is shown below. Figure 3 , Figure 5 As shown in the image.

[0065] Specifically, a sealing plate 11 is provided on the side of the end plate 12 facing the interior of the gap, and two corresponding fixing points 2 on the two adjacent side walls 31 abut against the two sides of the sealing plate 11; the sealing plate 11 is fixedly connected to the fixing points 2, embedding the end plate 12 into the gap, and the exposed surface of the end plate 12 is flush with the outer surface of the cabinet 3 on the corresponding side.

[0066] In one specific embodiment, the two end plates 12 may have relatively independent sealing plates 11, so as to facilitate independent installation on the front and rear sides of the gap. When the two end plates 12 are assembled based on the sealing plates 11 and the fixed support points 2, they can be installed independently without affecting each other. The two cabinets 3 share a single gap for heat dissipation.

[0067] For example, each of the two end plates 12 is provided with a sealing plate 11 facing the inside of the gap, and a fixing point 2 is provided at each of the four corners of the two side walls 31. The two pairs of fixing points 2 on the front side are used to fix the sealing plate 11 extending from the end plate 12 on the front side; the two pairs of fixing points 2 on the rear side are used to fix the sealing plate 11 extending from the end plate 12 on the rear side.

[0068] In another specific embodiment, a sealing plate 11 is shared by both cabinets 3. The sealing plate 11 is fixed based on the fixed fulcrum 2, so that the fixed position of the sealing plate 11 is far away from the side wall 31, thereby increasing the heat dissipation space of the side wall 31. A gap can be formed between the sealing plate 11 and the side wall 31 of the single cabinet 3, and the airflow in the side cabinet 3 can flow upward along the gap and out from the top of the side sealing structure 1. It can be used in conjunction with the heat dissipation structure of the cabinet 3, the heat dissipation structure in the computer room, etc. to achieve heat dissipation circulation. During assembly, the end plates 12 on the front and rear sides are fixed to the two ends of a sealing plate 11 and should be assembled simultaneously. They have a certain influence on each other, and the flatness of the sealing plate 11 needs to be ensured. The sealing plate 11 divides the gap between the two cabinets 3 into two thinner gaps, namely the left gap one and the right gap two. Each of the two cabinets 3 has a relatively independent thin gap. The left cabinet 3 corresponds to the left gap one, and the right cabinet 3 corresponds to the right gap two. The airflow direction and velocity between the two thin gaps may be the same or different.

[0069] For example, a sealing plate 11 is provided inside the gap of the two end plates 12, and a fixed support point 2 is provided at each of the four corners of the two side walls 31. The four pairs of fixed support points 2 fix the sealing plate 11 flatly to the outside of the side wall 31.

[0070] In this application, the sealing plate 11 is fixed to the side walls 31 of the two cabinets 3 by the fixed support point 2. Since the sealing plate 11 is shared, the gap formed between the sealing plate 11 and the side walls 31 of the two cabinets 3 can be one or two.

[0071] In a feasible embodiment, when the gap is not needed on one side of the cabinet 3, the gap can be formed only on the other side. For example, no fixed support point 2 is provided on the left cabinet, but a fixed support point 2 is provided on the right cabinet. The sealing plate 11 is completely fitted and fixed to the side wall 31 of the left cabinet, while the side wall 31 of the right cabinet is supported by the fixed support point 2 to form a gap. In this case, the sealing plate 11 and the side wall 31 can be in a non-parallel state, which can be determined by the length of the fixed support point 2.

[0072] For example, for the side wall 31 of the right cabinet, a fixed support point 2 can be provided at each of the four corners of the side wall 31. The four fixed support points 2 can be of the same length, and the four fixed support points 2 can fix the sealing plate 11 flatly to the outside of the side wall 31. Of course, the lengths of the four fixed support points 2 can also be different. For example, the two fixed support points 2 located on the front side can be of the same length, but longer than the two fixed support points 2 located on the rear side. In this case, the sealing plate 11 and the side wall 31 are in a relatively inclined state.

[0073] In a preferred embodiment, gaps can be formed between the sealing plate 11 and the side walls 31 of the double-sided cabinet 3, such as... Figure 5 , Figure 6As shown in the diagram. At this time, the sealing plate 11 is parallel to the two adjacent side walls 31.

[0074] For example, a fixed support point 2 is provided at each of the four corners of two adjacent side walls 31. The eight fixed support points 2 have the same length, and the four pairs of fixed support points 2 fix the sealing plate 11 flatly in the middle of the two side walls 31. Of course, when maintaining the parallel state, the lengths of the fixed support points 2 on the two side walls 31 can be different. For example, the four fixed support points 2 on the right side wall have the same length, which is the first length; the four fixed support points 2 on the left side wall have the same length, which is the second length. Making the first length greater than the second length can also ensure the parallel state of the sealing plate 11 with the two side walls 31, but the sealing plate 11 is not located in the middle.

[0075] To ensure even heat dissipation on both sides of the cabinet 3, the sealing plate 11 can be placed in the center. However, the position of the sealing plate 11 between the two side walls 31 can also be adjusted according to actual needs.

[0076] In the embodiments of this application, the fixed fulcrum 2 can be an insulating sleeve of different lengths or an insulating support block of a fixed length. The insulating sleeve of different lengths can be used as an adjustment component and can be selected according to actual needs to achieve the requirement that the sealing plate 11 is located in a specific position. The insulating support block of a fixed length can be used as a standard component to achieve the requirement that the sealing plate 11 is located in the center.

[0077] When fixing, long screws and nuts can be used to secure the sealing plate 11 between the two side walls 31, such as... Figure 6 As shown, a through hole 8 can be made on the sealing plate 11 by alignment, such as... Figure 9 As shown in the image.

[0078] Of course, the sealing plate 11 can also be clamped or positioned by a pair of fixed support points 2 on the two side walls 31 and suspended between the two side walls 31; the fixed support points 2 are connected to screws, which are screwed through the side walls 31 and fixed to the fixed support points 2. By rotating the screws, the distance between the fixed support points 2 and the sealing plate 11 can be adjusted; the fixed support points 2 on both sides of the sealing plate 11 can be kept in sync so that the sealing plate 11 is in the middle; if they are not in sync, the position of the sealing plate 11 can be adjusted, for example, more inclined to the right side of the cabinet.

[0079] This application uses end plates 12 to seal the front and back sides of the gap, forming the same structural effect as when only cabinet 3 is placed side by side. The following will be explained with the example of sealing plate 11 located in the middle and two end plates 12 sharing one sealing plate 11.

[0080] In one specific embodiment, the end plate 12 is vertically sealed to the side end of the sealing plate 11, the end plate 12 is embedded between two adjacent side walls 31, and the outer surface of the end plate 12 is flush with the front or rear surface of the two adjacent cabinets 3.

[0081] Specifically, end plates 12 are provided at both the front and rear ends of the sealing plate 11, and the two end plates 12 respectively seal the front and rear sides of the gap; at one end of the side sealing structure 1, such as Figure 7 As shown, the side end of the sealing plate 11 is vertically fixed to the center line of the end plate 12, dividing the end plate 12 into two parts, respectively sealing the rear side of the gap on the left and the gap on the right; similarly, the front side of the gap is also sealed.

[0082] To facilitate assembly, the end plate 12 and the sealing plate 11 can be assembled by means of snap-fit ​​or detachable fastening; of course, the end plate 12 and the sealing plate 11 can be an integrated structure, but this is not conducive to transportation and storage, and may cause structural damage; it is also not beneficial to the functional implementation of the end plate 12, and requires high dimensional accuracy of the fixed support point 2 and high bottom fixing accuracy of the cabinet 3.

[0083] In one feasible embodiment, the end plate 12 and the sealing plate 11 can be connected by a snap-fit. A clip 5 is provided at the middle position of the inner side of the end plate 12, and a slot 6 is provided at the side end of the sealing plate 11. The clip 5 is snapped into the slot 6, and the outer surface of the end plate 12 is flush with the front or rear surface of the two adjacent cabinets 3.

[0084] It is understood that regardless of whether the two end plates 12 share a sealing plate 11, the mating relationship between the end plates 12 and the sealing plate 11 can be adopted as described in the above embodiment. When the two end plates 12 share a sealing plate 11, the mating relationship described in the above embodiment is more preferred.

[0085] The end plate 12 extends from the top to the bottom of the cabinet 3 and is embedded in the gap. Its two ends should abut against the two side walls 31 so that the side-by-side structure of the two cabinets 3 is seamless.

[0086] Therefore, abutment bodies 4 can be provided inward on both sides of the end plate 12. The abutment bodies 4 can be right-angled structures, such as... Figure 7 As shown, the outer wall of the abutment 4 can abut against the side wall 31, and can effectively seal the gap provided that the sealing plate 11 is parallel to the side wall 31; the clip 5 is located between the abutments 4 on both sides, and the abutments 4 on both sides abut against the two adjacent side walls 31 respectively.

[0087] The abutting body 4 is used to abut between the side walls 31, and can achieve fixation in the form of adhesive, snap-fit, etc., so that the end plate 12 can be fixed to the side wall 31 without the help of the fixing fulcrum 2.

[0088] For the sake of structural compactness and the flatness of the cabinet 3, the fixed support point 2 can be located between the two end plates 12.

[0089] This utility model also provides an integrated cabinet assembly, consisting of multiple cabinets and multiple side sealing structures 1 as described above. The multiple cabinets are placed side-by-side, with a side sealing structure 1 positioned between two adjacent cabinets. Figure 10 As shown in the image.

[0090] The multiple cabinets 3 contained in the integrated cabinet group may be of the same or different types, but their external dimensions should be the same. After installation at the same height, the two adjacent side walls 31 between the parallel cabinets 3 can be completely aligned, so that the fixed support points 2 on the two adjacent side walls 31 can be connected one by one, forming a symmetrical state, which facilitates the assembly of the side sealing structure 1.

[0091] For example, a single cabinet in an integrated cabinet group can be a high-voltage distribution cabinet, a medium-voltage distribution cabinet, or a low-voltage distribution cabinet. The side sealing structure 1 can be applied to different types of distribution cabinets. When multiple distribution cabinets are installed in a centralized and parallel manner, the heat dissipation performance is improved through the side sealing structure 1.

[0092] In this application, the fixed fulcrum 2 can be a support structure, such as... Figure 2 The "C"-shaped structure shown can also be a cylindrical insulator, such as... Figure 4 As shown in the figure. When the fixed support point 2 adopts a bracket structure, the gap constructed by it has basically the same usage properties and conditions as that of the independent sealing plate 11. The shared sealing plate 11 is different from the former two. The following description is based on the independent sealing plate 11 and the shared sealing plate 11. The bracket structure and the independent sealing plate 11 are basically the same in terms of applicable scenarios.

[0093] When applicable to different types of distribution cabinets, the structure of the sealing plate 11 can be adjusted accordingly based on the execution standards (such as 3C standards) of different types of distribution cabinets, and the appropriate form can be selected independently.

[0094] In a specific example, the side sealing structure 1 can be applied to a high-voltage distribution cabinet. Based on practical considerations, a through-wall bushing is configured between the side walls 31 of the two high-voltage cabinets, with a copper busbar passing through the middle of the bushing to connect the electrical equipment inside the two cabinets. In this application scenario, no ventilation holes 7 are provided on the side walls 31, and the two end plates 12 can share a single sealing plate 11. This sealing plate does not require an array layout of ventilation holes 7. The shared sealing plate 11 provides a separation effect, requiring only the through-hole for the through-wall bushing, effectively preventing spark splashing between cabinets and avoiding the spread of fire to adjacent cabinets. When the end plates 12 are equipped with independent sealing plates 11, the two high-voltage cabinets share a single gap. In this case, the sealing plate 11 does not provide a separation effect, and there is no need to provide the through-hole for the through-wall bushing; the sealing of the side walls 31 prevents spark splashing between cabinets and avoids the spread of fire to adjacent cabinets.

[0095] Furthermore, each cabinet in the integrated cabinet group can be a high-voltage cabinet, and the size of the fixed support point 2 can be adjusted according to actual needs. There is a certain clearance between the wall bushings on the side walls 31 of the two high-voltage cabinets, and the size of the fixed support point 2 can be laid out and set based on this clearance. For example, the fixed support point 2 uses an insulator with a height of 110mm and a diameter of 70mm.

[0096] At this time, each cabinet in the integrated cabinet group is a relatively independent heat sink, and there is no airflow interaction between the cabinets through the sealing plate 11; the improvement of heat dissipation effect relies on the heat dissipation path / space formed by the gap between the side walls 31, and the airflow in the gap can flow upward along the gap; if an active heat dissipation device is configured at the bottom of the gap, the airflow can also flow downward along the gap.

[0097] In another specific example, the side sealing structure 1 can be applied to medium and low voltage distribution cabinets. If two end plates 12 share a sealing plate 11, a certain number of ventilation holes 7 can be mounted on the shared sealing plate 11 and arranged in an array, such as... Figure 9 As shown in the image.

[0098] Of course, when the side sealing structure 1 is applied to medium and low voltage distribution cabinets, ventilation holes 7 can be opened on the side wall 31, and ventilation holes 7 are not provided on the common sealing plate 11. In this case, the common sealing plate 11 can play a role in separation. Each cabinet 3 relies on its own ventilation and heat dissipation system for heat dissipation, while the airflow inside the gap can flow upward from the gap (if the lower part of the gap is equipped with an active heat dissipation device, the airflow can also flow downward along the gap), and a new heat dissipation path / space is constructed with the help of the side wall 31.

[0099] For overall structural considerations, and without creating safety hazards, ventilation holes 7 are provided on the side wall 31 and the sealing plate 11 shared by the end plates 12. In this case, convection can be formed between the cabinets 3 on both sides of the sealing plate 11, and the entire integrated cabinet group can form a heat dissipation body with a large airflow and wide flow range, which helps to dissipate heat. When the end plate 12 uses an independent sealing plate 11, the sealing plate 11 does not need to have ventilation holes 7 to form convection between cabinets.

[0100] Meanwhile, based on the distribution of equipment within cabinet 3, ventilation holes 7 can be strategically positioned on the shared sealing plate 11. Figure 8The diagram shows the layout of a conventional sealing plate on the side wall 31, which is configured based on the layered structure inside the cabinet 3. The conventional sealing plate includes three plates: a first plate 311, a second plate 312, and a third plate 313, which correspond to the three layers inside the cabinet 3. The diagram also shows the positional relationship between the fixed support point 2 and the three plates when the fixed support point 2 is configured on the side wall 31. Based on this, the distribution area of ​​ventilation holes 7 can be aligned on the common sealing plate 11, corresponding to the first equipment layer at the same height as the first plate 311, the second equipment layer at the same height as the second plate 312, and the third equipment layer at the same height as the third plate 313.

[0101] In one feasible embodiment, multiple ventilation holes 7 are arranged in an array on a common sealing plate 11 to form a ventilation hole array. The ventilation hole array includes a first zone 71, a second zone 72, and a third zone 73 from top to bottom. The first zone 71 is at the same height as the first equipment layer inside the cabinet 3, the second zone 72 is at the same height as the second equipment layer inside the cabinet 3, and the third zone 73 is at the same height as the third equipment layer inside the cabinet 3.
