[0033] See also Figure 1-6 As shown, in this embodiment, a control cabinet with a heat dissipation structure is provided, comprising: a cabinet body 1, a cabinet door 2 is provided at the front opening of the cabinet body 1, a plurality of control display screens 3 and a plurality of control buttons 4 are fixedly embedded on the cabinet door 2, the control display screen 3 is used to display the control parameters of the control cabinet, and the control buttons 4 are used to input the control parameters of the control cabinet, one side of the cabinet door 2 is rotatably connected to one side of the edge of the front opening of the cabinet body 1, and the cabinet door 2 can close the front opening of the cabinet body 1;
[0034] Side openings are provided on both sides of the cabinet 1, and heat dissipation components are fixedly connected to the outer walls of both sides of the cabinet 1. The heat dissipation components include a heat dissipation frame 5 and a heat dissipation device. The heat dissipation frame 5 can close the side openings; the heat dissipation device is fixedly connected to the inside of the heat dissipation frame 5.
[0035] The heat dissipation component includes a drive motor 10, a plurality of blades 26 and a plurality of impeller discs 25 from top to bottom. The output shaft of the drive motor 10 is fixedly connected to the rotating shaft 11. The plurality of impeller discs 25 are fixedly sleeved on the rotating shaft 11 at intervals. A plurality of blades 26 are fixedly inserted between two adjacent impeller discs 25 at intervals. A plurality of air inlets 27 are provided at the bottom of the impeller disc 25 farthest from the drive motor 10.
[0036] One aspect of the application of this embodiment is: when the control cabinet with the heat dissipation structure is used, the heat dissipation assembly is connected to both sides of the cabinet 1, and the heat dissipation device is connected to the inside of the heat dissipation frame 5. By starting the drive motor 10 in the heat dissipation device, the rotation of the output shaft of the drive motor 10 will drive the rotation of the rotating shaft 11, and then drive the plurality of blades 26 on the impeller disk 25 to rotate, and enter the heat dissipation frame 5 through the air inlet 27 on the impeller disk 25, so as to achieve heat dissipation of the electronic components in the control cabinet. In this device, the air inlet 27 is arranged at the bottom of the impeller disk 25 farthest from the drive motor 10, that is, at the bottom of the heat dissipation frame 5, so as to reduce the risk that splashing rainwater in the outdoor environment may enter the cabinet 1 through the air inlet 27 to damage its internal electronic components, and enhance the protective performance of the heat dissipation structure.
[0037] In this embodiment, the heat dissipation frame 5 includes a first frame 5-1 and a second frame 5-2 which are interconnected. The heat dissipation device is located inside the first frame 5-1. The second frame 5-2 is connected to the side opening of the cabinet 1. The second frame 5-2 includes a plurality of vertically spaced splitters 7. The splitters 7 are fixedly connected to the inner wall of the second frame 5-2 so that the second frame 5-2 forms a plurality of air ducts 8. The heat dissipation device generates cold air in the air cavity 6 of the first frame 5-1. The cold air enters the second frame 5-2 through the plurality of air ducts 8 and then enters the cabinet 1 to achieve heat dissipation of the electronic components in the cabinet 1. By providing a plurality of splitters 7 to generate a plurality of air ducts 8, the heat dissipation of the cabinet 1 is more uniform.
[0038] In this embodiment, the cross-sectional shape of the heat dissipation frame 5 is pyramid-shaped, and the length of the cross-sectional shape of the first frame 5-1 is less than the length of the cross-sectional shape of the second frame 5-2, the bottom surface of the first frame 5-1 is lower than the bottom surface of the second frame 5-2, and the cross-sectional shapes of several diverter plates 7 are adapted to the cross-sectional shapes of the second frame 5-2. The heat dissipation frame 5 is set to be pyramid-shaped, so that the volume of the heat dissipation frame 5 is smaller and the weight of the heat dissipation frame 5 is reduced. The cross-sectional shapes of several diverter plates 7 are adapted to the cross-sectional shape of the second frame 5-2, so that the cold air entering the cabinet 1 is more uniform, and the heat dissipation of the cabinet 1 is also more uniform.
[0039] In this embodiment, a through hole 9 is provided at the top of the first frame 5-1, a driving motor 10 is fixedly arranged on the top of the first frame 5-1, and a rotating shaft 11 is rotatably connected in the through hole 9. The driving motor 10 is arranged outside the heat dissipation frame 5 so that the heat generated by the driving motor 10 itself will not enter the heat dissipation frame 5, thereby reducing the transfer of heat.
[0040] In this embodiment, the heat dissipation assembly further includes a filter plate 12, which is located below the air inlet 27. A sliding groove 18 is provided at the lower part of the side of the first frame 5-1 away from the cabinet 1. An upper tooth plate 22-1 and a lower tooth plate 22-2 are arranged above the sliding groove 18, and the upper tooth plate 22-1 and the lower tooth plate 22-2 are arranged in parallel. The opposing surfaces of the upper tooth plate 22-1 and the lower tooth plate 22-2 are respectively provided with teeth. A gear 23 is provided between the upper tooth plate 22-1 and the lower tooth plate 22-2, and the gear 23 is meshed with the teeth. The side of the gear 23 away from the cabinet 1 is fixedly connected to one end of the adjustment rod 20, and the other end of the adjustment rod 20 is fixedly connected to the handle 28. The side of the gear 23 close to the cabinet 1 is fixedly connected to one end of the torsion spring 24, and the other end of the torsion spring 24 is fixedly connected to the inner wall of the sliding groove 18. Dust or impurities in the external environment will enter the cabinet 1 through the heat dissipation frame 5, thereby affecting the service life of the electronic components in the cabinet 1. By setting a filter plate 12 below the air inlet 27, the cold air entering the cabinet 1 is filtered, and the dust or impurities entering the cabinet 1 are filtered out, thereby reducing the risk of dust or impurities entering the cabinet 1 and reducing the service life of electronic components in the cabinet 1.
[0041] In this embodiment, the end of the upper tooth plate 22-1 away from the adjusting rod 20 is fixedly connected to the upper moving block 19-1, and the end of the lower tooth plate 22-2 away from the adjusting rod 20 is fixedly connected to the lower moving block 19-2. The upper end of the upper moving block 19-1 is fixedly connected to the upper clamping block 21-1, and the upper end of the lower moving block 19-2 is fixedly connected to the lower clamping block 21-2. The upper clamping block 21-1 has the same shape as the lower clamping block 21-2. The height of the upper moving block 19-1 is less than the height of the lower moving block 19-2, so that the upper surface of the upper clamping block 21-1 is flush with the upper surface of the lower clamping block 21-2. The front and rear sides of the filter plate 12 are respectively provided with clamping grooves 15, and the upper clamping block 21-1 and the lower clamping block 21-2 match the shape of the clamping groove 15 and can be clamped into the clamping groove 15.
[0042] In this embodiment, a positioning hole is provided on the inner wall of the first frame 5-1 near the lower end of the cabinet 1, and a positioning column 16 is fixedly connected to the side of the filter plate 12 near the cabinet 1. The positioning column 16 can be connected in the positioning hole, and a plurality of filter holes 13 are provided on the filter plate 12.
[0043] Another application of this embodiment is: when installing the filter plate 12, the filter plate 12 is placed in the sliding groove 18, so that the positioning column 16 on the filter plate 12 is aligned and inserted into the positioning hole 17 on the first frame 5-1. Due to the elasticity of the torsion spring, the upper clamping block 21-1 and the lower clamping block 21-2 are respectively matched and connected to the clamping groove 15 on the filter plate 12, thereby achieving fixed installation of the filter plate 12. When removing the filter plate 12, the handle 28 is rotated, and the rotation of the handle 28 drives the rotation of the adjusting rod 20, and the rotation of the adjusting rod 20 drives the rotation of the gear 23. Since the gear 23 is meshed with the teeth of the upper tooth plate 22-1 and the lower tooth plate 22-1, the upper tooth plate 22-1 and the lower tooth plate 22-2 rotate the gear 23 in the direction away from each other, and the upper tooth plate 22-1 and the lower tooth plate 22-2 move away from each other, which drives the upper moving block 19-1 and the lower moving block 19-2 to move away from each other, and then drives the upper clamping block 21-1 and the lower clamping block 21-2 to move away from each other, so that the upper clamping block 21-1 and the lower clamping block 21-2 are respectively separated from the clamping slot 15, and the filter plate 12 can be removed, that is, the filter plate 12 can be disassembled and assembled. Through the setting of this device, the detachability of the filter plate 12 is improved, the stability of the installation of the filter plate 12 is guaranteed, and the filter plate 12 is more convenient to clean and replace.
[0044] In this embodiment, the length of the upper tooth plate and the lower tooth plate is less than the opening length of the sliding slot 18, and is greater than 1 / 2 of the opening length of the sliding slot 18, and a handle 14 is fixedly connected to the side of the filter plate 12 away from the cabinet 1. The slidability of the filter plate 12 in the sliding slot 18 is improved, and it is also more convenient to replace the filter plate 12.
[0045] In this embodiment, there are three impeller disks 25 , and each blade 26 penetrates the middle impeller disk 25 and is inserted between the impeller disks 25 at both ends in an inclined manner, thereby increasing the heat dissipation effect of the blades.
