Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for power distribution cabinets, specifically a heat dissipation structure for power distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment in the power distribution system and are used in situations where the loads are relatively dispersed and there are few circuits. They distribute the electrical energy of a certain circuit of the previous stage power distribution equipment to the nearest load. This stage of equipment should provide protection, monitoring, and control for the load. All electrical components and lines in the distribution cabinet should have good contact and reliable connection; there should be no serious overheating or burning. The door of the distribution cabinet should be intact, and the door lock should be kept by a designated person.

[0003] Many outdoor power distribution cabinets have downward-facing ventilation holes on their surface, which serve to dissipate heat and prevent rainwater from entering the cabinet. However, these cabinets cannot adjust the distribution of ventilation holes according to the heat distribution inside the cabinet, nor can they adjust the heat dissipation effect according to the outside temperature. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation structure for a power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat dissipation structure for a power distribution cabinet includes a cabinet body, which includes a back panel, a top panel, a bottom panel, side panels, and uprights. Four uprights are vertically fixed between the top panel and the bottom panel. The back panel is fixedly installed between two uprights. The side panels are slidably connected between two uprights. Each side panel consists of a fixed plate and two heat dissipation plates. The two heat dissipation plates are respectively attached to the top and bottom of the fixed plate. Each heat dissipation plate has a through groove. Inside the through groove, a baffle is horizontally movably connected via two driving mechanisms. The surface of the baffle has a first heat dissipation hole, and the side of the baffle has a second heat dissipation hole.

[0007] Preferably, a blocking block is fixedly installed at the bottom of the inner wall of the second heat dissipation hole, and a waterproof slope is provided at the top of the blocking block, with the higher end of the waterproof slope close to the inside of the cabinet.

[0008] Preferably, the drive mechanism includes a bracket, a traction seat, a threaded rod, and a motor. The bracket is fixedly installed on the surface of the baffle, the threaded rod is rotatably connected between the bracket and the baffle, the motor is fixedly installed on the surface of the bracket and connected to the threaded rod, and the traction seat is threadedly connected to the surface of the threaded rod.

[0009] Preferably, the two drive mechanisms are symmetrically arranged on both sides of the middle part of the baffle.

[0010] Preferably, the fixing plate and the heat sink have the same area.

[0011] Preferably, the surface of the column is provided with grooves, and the fixing plate and the heat dissipation plate are vertically slidably connected between the two grooves.

[0012] Preferably, in the initial state, the second heat dissipation hole is located inside the cabinet, and the first heat dissipation hole is located outside the cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a vertically sliding fixed plate and two heat dissipation plates between two columns. During overall assembly, the positions of the two heat dissipation plates can be adjusted according to the specific distribution of internal electrical components, so that the heat dissipation plates correspond to the positions of electrical components with high heat dissipation, thereby improving the heat dissipation effect on these components. At the same time, the drive mechanism enables the baffle to slide horizontally inside the through groove, so that the position of the second heat dissipation hole can be adjusted according to the specific external temperature, thereby adjusting the specific heat dissipation effect.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a heat dissipation structure for a power distribution cabinet, including a cabinet body 1. The cabinet body 1 includes a back plate 2, a top plate 3, a bottom plate 4, side plates 5, and columns 6. The four columns 6 are vertically fixed between the top plate 3 and the bottom plate 4. The back plate 2 is fixedly installed between two columns 6. The side plates 5 are slidably connected between two columns 6. The side plates 5 consist of a fixed plate 7 and two heat dissipation plates 8. The two heat dissipation plates 8 are respectively attached to the top and bottom of the fixed plate 7. The heat dissipation plates 8 are provided with through grooves 9. The inside of the through grooves 9 is horizontally movably connected to baffles 10 through two driving mechanisms. The surface of the baffles 10 is provided with first heat dissipation holes 11, and the side of the baffles 10 is provided with second heat dissipation holes 12. In the initial state, the second heat dissipation holes 12 are located inside the cabinet body 1, and the first heat dissipation holes 11 are located outside the cabinet body 1.

[0024] Please see Figure 1 , Figure 2 and Figure 3 Since the side panel 5 is a modular structure, the specific positions of the two heat dissipation plates 8 and the fixed plate 7 are adjusted to match the actual electrical components inside the cabinet 1, so that the heat dissipation plates 8 can be installed near electrical components that generate a lot of heat. Thus, the position of the heat dissipation plates 8 can be adjusted during the assembly stage of the cabinet 1 according to the actual heat generation of the electrical components. In actual use, if the temperature of the external environment is high, the heat dissipation effect of the first heat dissipation hole 11 alone is not good. Therefore, in this embodiment, the baffle 10 can be driven to move horizontally inside the through groove 9 by the drive mechanism, so that the baffle 10 drives the second heat dissipation hole 12 from the inside of the cabinet 1 to the outside. At this time, the arrangement of the first heat dissipation hole 11 and the second heat dissipation hole 12 increases the unit amount of gas exchange between the inside of the cabinet 1 and the outside, thereby improving the heat dissipation effect.

[0025] A blocking block 13 is fixedly installed at the bottom of the inner wall of the second heat dissipation hole 12. A waterproof slope 14 is provided on the top of the blocking block 13, and the higher end of the waterproof slope 14 is close to the inside of the cabinet 1.

[0026] Please see Figure 5 and Figure 6For the first heat dissipation hole 11, its specific structure is a conventional waterproof heat dissipation hole in the prior art, which achieves the waterproof effect by changing the direction of the heat dissipation hole. However, in this embodiment, since the baffle 10 needs to move horizontally on the inner wall of the through groove 9, the surface of the second heat dissipation hole 12 needs to always be in contact with the inner wall of the through groove 9. Therefore, the surface of the second heat dissipation hole 12 cannot be provided with the same waterproof structure as the waterproof heat dissipation hole in the prior art. The waterproofing method provided in this embodiment is to add a blocking block 13 to the inner wall of the second heat dissipation hole 12, and to provide a waterproof slope 14 at the top of the blocking block 13 near the outside. When rainwater enters the interior of the second heat dissipation hole 12, it will fall on the surface of the waterproof slope 14. Under the action of gravity, the rainwater will slide off the waterproof slope 14, thereby preventing rainwater from further entering the interior of the second heat dissipation hole 12, so as to play a waterproof role for the interior of the cabinet 1.

[0027] The drive mechanism includes a bracket 15, a traction seat 16, a threaded rod 17, and a motor 18. The bracket 15 is fixedly installed on the surface of the baffle 10. The threaded rod 17 is rotatably connected between the bracket 15 and the baffle 10. The motor 18 is fixedly installed on the surface of the bracket 15 and connected to the threaded rod 17. The traction seat 16 is threadedly connected to the surface of the threaded rod 17. The two drive mechanisms are symmetrically arranged on both sides of the middle part of the baffle 10.

[0028] Please see Figure 3 and Figure 4 The motor 18 drives the threaded rod 17 to rotate, and the threaded rod 17 drives the baffle 10 to rotate synchronously. However, due to the restriction of the through groove 9, the baffle 10 can only move horizontally on the inner wall of the through groove 9. Therefore, the traction seat 16 can move horizontally on the surface of the threaded rod 17 so that the position of the baffle 10 inside the through groove 9 can be adjusted by the threaded rod 17. In this embodiment, the drive mechanism is symmetrically set to two, so that the power of the baffle 10 when moving can come from both sides of the middle part of the baffle 10, thereby realizing the smooth movement of the baffle 10.

[0029] The fixed plate 7 and the heat dissipation plate 8 have the same area. The surface of the column 6 is provided with a groove 19. The fixed plate 7 and the heat dissipation plate 8 are vertically slidably connected between the two grooves 19.

[0030] Please see Figure 2 In this embodiment, the areas of the fixing plate 7 and the heat dissipation plate 8 are set to be equal, so that the positions of one fixing plate 7 and two heat dissipation plates 8 can be arbitrarily combined and adjusted. The groove 19 can facilitate the limiting of the fixing plate 7 and the heat dissipation plate 8, and at the same time increases the contact area between the side plate 5 and the column 6, thereby increasing the overall sealing of the cabinet 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
