Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a cabinet structure with partitioned heat dissipation and airflow guidance. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] The cabinet of a power distribution cabinet mainly consists of a frame structure, outer shell, door panels, mounting plates, heat dissipation devices, and protective components. The frame structure is the "skeleton" of the entire cabinet, generally made of high-quality steel or aluminum alloy profiles, assembled through welding, riveting, or bolting to support the entire cabinet. The outer shell, covering the frame, primarily protects the internal electrical components. The outer shell is mostly made of cold-rolled steel or stainless steel and undergoes surface treatment for better rust and corrosion resistance. To ensure heat dissipation for the internal components, ventilation windows are located on the left and right sides of the cabinet. When placing the power distribution cabinet, since the back of the cabinet is against one side of the wall, heat generated by the internal components tends to concentrate at the back of the cabinet, making effective heat dissipation difficult and affecting the cabinet's overall cooling performance. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a cabinet structure with partitioned heat dissipation and airflow guidance to overcome the shortcomings of existing designs.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a cabinet structure with partitioned heat dissipation and airflow guidance, including a support frame, an outer cabinet on the outside of the support frame, and the outer cabinet and the support frame being detachably connected;

[0006] The back of the outer cabinet is equipped with a mounting frame, which is detachably connected to the outer cabinet. A water-cooling plate is provided inside the mounting frame, and the water-cooling plate is fixedly connected to the mounting frame.

[0007] The water-cooled plate consists of two corrugated cold-rolled plates, which are stacked and fixedly connected by welding. Multiple flow channels are formed between the two corrugated cold-rolled plates, and two adjacent flow channels are connected. The flow channels are connected to the cooling water circulation inlet located on the outside of the mounting frame.

[0008] A further improvement is that the mounting frame includes two vertically arranged first frame plates and two horizontally arranged second frame plates, with the first frame plates fixedly disposed between the two second frame plates, and the corrugated cold-rolled plate fixedly disposed between the two first frame plates and the two second frame plates.

[0009] A further improvement is that the cooling water circulation inlet includes a water injection pipe and a drain pipe, which are respectively fixedly installed on the outer side of two second frame plates. Multiple guide holes are opened on the inner side of the second frame plates. The water injection pipe is connected to one of the guide channels through the second frame plates, and the drain pipe is connected to another guide channel through the second frame plates. Two adjacent guide channels are connected through the guide holes.

[0010] A further improvement is that: the first frame plate is provided with multiple bolt plates on the side away from the water-cooling plate, the bolt plates are fixedly connected to the first frame plate, and the bolt plates are equipped with second fixing bolts, which pass through the bolt plates and are threadedly connected to the bolt holes opened on the back of the outer cabinet.

[0011] A further improvement is that the outer cabinet includes multiple outer panels, and the edges of the outer panels are fitted with several first fixing bolts. The first fixing bolts pass through the outer panels and are threadedly connected to bolt holes opened on the outside of the support frame.

[0012] A further improvement is that air inlets are provided on the left and right sides of the outer cabinet, and an exhaust vent is provided on the top of the outer cabinet. The exhaust vent is equipped with a mesh cover, which is detachably connected to the outer cabinet.

[0013] A further improvement is that: the upper end of the outer cabinet is provided with multiple support rods, the mesh cover is built on each support rod, and multiple third fixing bolts are installed on the outside of the mesh cover. Each third fixing bolt passes through the mesh cover and is threadedly connected to the bolt hole opened at the upper end of each support rod.

[0015] The water-cooled plate is welded from two corrugated cold-rolled plates. The space formed by the overlapping and welding of the two corrugated cold-rolled plates and the dense flow channels allows the cooling water to circulate through the cooling water circulation port, carrying away the excess heat concentrated in the rear half of the outer cabinet and effectively improving the heat dissipation efficiency of the cabinet. The mounting frame is detachably connected to the outer cabinet, making it easy to replace and maintain the water-cooled plate. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a cabinet structure with partitioned heat dissipation and airflow guidance, including a support frame 1, an outer cabinet 2 on the outside of the support frame 1, and the outer cabinet 2 being detachably connected to the support frame 1; the detachable installation method facilitates the separate disassembly and replacement of the outer cabinet 2.

[0026] The outer cabinet 2 has a mounting frame 4 on the back, which is detachably connected to the outer cabinet 2. The mounting frame 4 has a water-cooled plate 6 on the inside, which is fixedly connected to the mounting frame 4. The water-cooled plate 6 is set on the back of the outer cabinet 2 through the mounting frame 4, which is detachably connected to the outer cabinet 2, making it easy to replace and maintain the water-cooled plate 6.

[0027] The water-cooled plate 6 includes two corrugated cold-rolled plates 61, which are stacked and fixedly connected by welding. Multiple flow channels 62 are formed between the two corrugated cold-rolled plates 61, and two adjacent flow channels 62 are connected. The flow channels 62 are connected to the cooling water circulation inlet located on the outside of the mounting frame 4.

[0028] The water-cooled plate 6 is welded from two corrugated cold-rolled plates 61. The space formed by the overlapping and welding of the two corrugated cold-rolled plates 61 and the dense flow channels 62 allows cooling water to circulate through the cooling water circulation port, carrying away the excess heat concentrated in the rear half of the outer cabinet 2 and improving the heat dissipation efficiency of the cabinet.

[0029] It is worth explaining in detail that the mounting frame 4 includes two vertically arranged first frame plates 41 and two horizontally arranged second frame plates 45. The first frame plates 41 are fixedly disposed between the two second frame plates 45, and the corrugated cold-rolled sheet 61 is fixedly disposed between the two first frame plates 41 and the two second frame plates 45. The corrugated cold-rolled sheet 61 is also fixed to the first frame plates 41 and the second frame plates 45 by welding. During processing, it is necessary to ensure that there is no leakage between the first frame plates 41, the second frame plates 45 and the corrugated cold-rolled sheet 61.

[0030] It is worth explaining in detail that the cooling water circulation inlet includes a water inlet pipe 46 and a drain pipe 47. The water inlet pipe 46 and the drain pipe 47 are respectively fixed on the outer side of the two second frame plates 45. Multiple guide holes 48 are opened on the inner side of the second frame plates 45. The water inlet pipe 46 is connected to one of the guide channels 62 through the second frame plates 45, and the drain pipe 47 is connected to another guide channel 62 through the second frame plates 45. The two adjacent guide channels 62 are connected by the guide holes 48. The purpose of this design is that the dense guide channels 62 between the two corrugated cold-rolled plates 61 will form a serpentine channel structure. Cooling water enters the guide channels 62 through the water inlet pipe 46, and then circulates in each guide channel 62. After carrying away the excess heat in the outer cabinet 2, it is discharged to the outside through the drain pipe 47. The water inlet pipe 46 is connected to the circulating water pump.

[0031] To facilitate the replacement and maintenance of the water-cooled plate 6, in a preferred embodiment, the first frame plate 41 has multiple bolt plates 42 on the side away from the water-cooled plate 6. The bolt plates 42 are fixedly connected to the first frame plate 41, and a second fixing bolt 43 is mounted on the bolt plate 42. The second fixing bolt 43 passes through the bolt plate 42 and is threadedly connected to a bolt hole on the back of the outer cabinet 2. When removing the water-cooled plate 6 from the back of the outer cabinet 2, the second fixing bolt 43 on the bolt plate 42 is simply unscrewed from the bolt hole on the back of the outer cabinet 2.

[0032] The outer cabinet 2 adopts a split design. Specifically, the outer cabinet 2 includes multiple outer panels, and several first fixing bolts 8 are fitted along the edges of the outer panels. The first fixing bolts 8 pass through the outer panels and are threadedly connected to bolt holes opened on the outside of the support frame 1. Similarly, the outer panels are also fixed to the outside of the support frame 1 by bolt connection, which will not be explained in detail here.

[0033] To facilitate air circulation, air inlets 3 are provided on the left and right sides of the outer cabinet 2, and an exhaust vent 7 is provided on the top of the outer cabinet 2. A mesh cover 10 is provided on the exhaust vent 7, and the mesh cover 10 is detachably connected to the outer cabinet 2. A negative pressure fan is installed inside the mesh cover 10, which is installed on the top of the outer cabinet 2. The fan is used to extract air from the outer cabinet 2, so that cold air from outside can circulate into the support frame 1 through the air inlets 3. The mesh cover 10 also serves to prevent dust.

[0034] To facilitate cleaning of the mesh cover 10, the mesh cover 10 is also installed on the top of the outer cabinet 2 using a bolt connection method. Specifically, the upper end of the outer cabinet 2 is provided with multiple support rods 9, and the mesh cover 10 is built on each support rod 9. Multiple third fixing bolts 11 are fitted on the outside of the mesh cover 10, and each third fixing bolt 11 passes through the mesh cover 10 and is threadedly connected to the bolt holes opened on the upper end of each support rod 9.

[0035] How this application works:

[0036] The water-cooled plate 6 is mounted on the back of the outer cabinet 2 via the mounting frame 4. The water-cooled plate 6 is welded from two corrugated cold-rolled plates 61. Within the space formed by the overlapping and welding of the two corrugated cold-rolled plates 61, which consists of dense flow channels 62, cooling water circulates through the cooling water circulation port, carrying away excess heat concentrated in the rear half of the outer cabinet 2 and improving the cabinet's heat dissipation efficiency. The mounting frame 4 is detachably connected to the outer cabinet 2, and the outer cabinet 2 is detachably connected to the support frame 1, making it easy to disassemble and replace the outer cabinet 2 and the water-cooled plate 6.
