Description

Technical Field

[0001] The invention belongs to the technical field of dustproof cabinets, and in particular relates to a conductive dustproof cabinet. Background Art

[0002] In some specific industries, such as aerospace, aviation, food processing, etc., a large amount of conductive dust, such as carbon fiber dust, flour dust, etc., is generated during the production process. If these dusts enter the interior of the cabinet, they will adhere to the electrical components, affecting their conductivity, and easily cause faults such as short circuits and burns. In addition, dust accumulation will also affect the heat dissipation effect, causing the equipment temperature to be too high, accelerating equipment aging, and may even cause fires under the action of electric arcs. Therefore, in order to ensure the safety and stable operation of the equipment, it is necessary to design a cabinet that can effectively prevent the entry of conductive dust and effectively dissipate heat from the cabinet. Traditional electrical cabinets are mostly fan-ventilated or external air-conditioning types, with poor sealing and difficulty in effectively blocking dust. If faults caused by dust occur frequently, it will not only increase the maintenance cost, but also be difficult to repair in time due to the out-of-stock of some electrical components, resulting in greater economic losses. Therefore, from the perspective of economic cost and maintenance difficulty, it is also necessary to develop a conductive dust-proof cabinet that can operate stably for a long time, reduce the frequency of faults, and has a cooling system.

[0018] Embodiment: A conductive dust proof cabinet, such as Figure 1-Figure 5 As shown, it includes a cabinet, a partition 2 is provided inside the cabinet 1, and a fan installation hole 3 and a heat dissipation window 4 are respectively opened on both sides of the cabinet 1 on the upper side of the partition 2, the fan installation hole 3 is arranged on the left side of the cabinet 1, and the heat dissipation window 4 is arranged on the right side of the cabinet 1, a cooling fan 5 is installed in the fan installation hole 3, and the cooling fan 5 is provided with a filter housing 6 facing the inner side of the cabinet 1, a filter screen 7 is provided in the filter housing 6, and a wind speed measuring instrument 8 is provided on the filter housing 6;

[0019] A heat exchange plate assembly 9 is provided in the cabinet 1 on the upper side of the partition 2, and a heat exchange tube assembly 10 is provided in the cabinet 1 on the lower side of the partition 2. The heat exchange plate assembly 9 includes a heat exchange tube sheet 11, and the heat exchange tube sheet 11 is provided on the upper surface of the partition 2. A plurality of air guide plates 12 are provided between the heat exchange tube sheet 11 and the filter housing 6;

[0020] The heat exchange tube assembly 10 includes a copper mounting plate 13, a circulating copper tube 14 is provided on the rear surface of the copper mounting plate 13, the circulating copper tube 14 is welded to the copper mounting plate 13, a plurality of fins 15 are provided on the rear surface of the copper mounting plate 13, the plurality of fins 15 surround the circulating copper tube 14 at the same time, the copper mounting plate 13 is provided with screw holes for installing electrical equipment, the screw holes are arranged to avoid the fins 15 and the circulating copper tube 14, the circulating copper tube 14 and the heat exchange tube sheet 11 each include an inlet 16 and an outlet 17, the inlet 16 and outlet 17 of the heat exchange tube sheet 11 extend through the partition 2 to the lower surface of the partition 2, the inlet 16 of the circulating copper tube 14 is connected to the outlet 17 of the heat exchange tube sheet 11, the outlet 17 of the circulating copper tube 14 is connected to the inlet 16 of the heat exchange tube sheet 11, and a circulating water pump 18 is provided at the inlet 16 end of the circulating tube sheet.

[0021] The bottom of the cabinet 1 is provided with a spliced ​​wall plate 19; the bottom of the circulating copper pipe 14 is provided with a drain port 20; the cabinet 1 includes a cabinet door, and the cabinet door is provided with a temperature probe 21 and a temperature controller 22.

[0022] The principle of the present invention is as follows: the water in the cabinet is circulated by the circulating water pump 18, and the hot water after heat exchange is transported to the heat exchange plate assembly 9. The air outside the cabinet is fully contacted with the heat exchange tube plate 11 through the guide plate by the cooling fan 5, and the circulating water is fully cooled to achieve the reuse of the circulating water; the temperature in the cabinet is fed back to the thermostat through the temperature probe 21PT100. When the set temperature value (35°C) is reached, the thermostat controls the cooling fan 5 to run and cool the circulating water. When the temperature is lower than the set temperature, the cooling fan 5 is not triggered to run, which plays a role in saving electric energy; the wind speed measuring instrument 8 is installed at the filter housing 6, and it is found that when the wind speed is lower than 10m 3 / min and the fan is started, if it is judged that the filter 7 is blocked, the air volume tester will be triggered to alarm so that the filter 7 can be replaced in time. The upper cabinet 1 is isolated from the electrical installation room by the partition 2 (matched with the protection level to achieve IP55 and above). Even if some dust enters the upper cabinet 1 through the filter 7, it can effectively prevent the charged dust from entering the lower cabinet 1 to achieve effective isolation. The cables in the cabinet pass through the bottom assembled wall plate, which not only ensures the convenience of threading but also ensures the protection level of the cabinet.

[0023] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
