Description

Technical Field

[0001] The utility model relates to a heat dissipation system, in particular to a dedicated heat dissipation system device for a full-steel tire substation. Background Art

[0002] At present, the substations of each workshop of my country's all-steel tire production enterprises are designed inside the workshop according to the design institute's practice. Dry-type transformers are used to transform the voltage from 10kV to 690V or 400V. The substation is adjacent to the carbon black working environment of the mixing workshop. The amount of carbon black dust is large, the particles are small, and it is easy to float, resulting in a lot of carbon black inside the substation, which has a great impact on the environment and safety of the substation. Because there is carbon black dust in the mixing workshop, the design institute often places the inverter and other control devices of the workshop equipment in the substation, resulting in an increase in the heat source in the substation. At the same time, the temperature in the production workshop is also high, resulting in a high overall temperature of the substation. A dust-proof and heat-dissipating system for substations with inverters installed in tire production workshops is needed. Utility Model Content

[0003] The purpose of the utility model is to provide a dedicated heat dissipation system device for a full-steel tire substation to solve the above technical problems.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dedicated heat dissipation system device for a full-steel tire substation, including an external air duct, an exhaust duct inside the cabinet, a straight air duct, an air supply unit, a cold air duct, a combined air-conditioning unit, an internal circulation air duct, an exhaust outlet, a double-layer louvered hood, and a filter element. The front end of the external air duct is installed with the internal exhaust duct, the straight air duct is distributed at the left and right ends of the internal exhaust duct, the air supply unit is installed at the rear end of the external air duct, the cold air duct is installed at the right part of the air supply unit, the combined air-conditioning unit is installed in the cold air duct, the rear part of the internal circulation air duct is connected to the cold air duct through the combined air-conditioning unit, the exhaust outlet is distributed at the side end of the internal exhaust duct, the double-layer louvered hood is installed at the exhaust outlet, and the filter element is installed inside the double-layer louvered hood.

[0005] On the basis of the above technical scheme, the internal circulation air duct includes an air duct, an air valve, an air inlet, and a circulating air outlet. The air valve is installed at the rear of the air duct and is connected to the cold air duct. The air inlet is opened at the front of the air duct and a double-layer louvered wind hood is installed at the air inlet. The circulating air outlet is opened at the rear of the air duct, and the air duct is connected to the combined air-conditioning unit through the circulating air outlet.

[0006] Based on the above technical solution, the air inlet and the air outlet are located inside the substation to form circulating air.

[0007] Based on the above technical solution, the air volume circulated by the air inlet is smaller than the air volume exhausted by the exhaust duct in the cabinet.

[0008] Compared with the prior art, the utility model has the following advantages: The utility model adopts a centralized air supply mode inside the substation through the internal exhaust air duct in the cabinet, and realizes the cooling air of two modes of cold air and natural air through the air blower unit and the combined air conditioning unit. Cooperating with the internal circulation air duct creates a positive pressure system inside the substation, which plays a role in blocking dust. While the hot air is directly discharged, a fresh air circulation is formed at the same time, reducing the dust concentration in the substation, reducing equipment failures and improving safety.

[0013] The following further elaborates on the utility model in detail with reference to the drawings and specific embodiments.

[0014] As Figures 1 to 3 shown, a special heat dissipation system device for collection and distribution in a steel tire substation includes an external air duct 1 of the cabinet, an internal exhaust air duct 2 of the cabinet, a direct ventilation cylinder 3, an air blower unit 4, a cold air duct 5, a combined air conditioning unit 6, an internal circulation air duct 7, an exhaust port 8, a double-layer louvered air hood 9, and a filter element 10. The front end of the external air duct 1 of the cabinet is installed with the internal exhaust air duct 2 of the cabinet. The direct ventilation cylinders 3 are distributed at the left and right ends of the internal exhaust air duct 2 of the cabinet. The air blower unit 4 is installed at the rear end of the external air duct 1 of the cabinet. The cold air duct 5 is installed on the right side of the air blower unit 4. The combined air conditioning unit 6 is installed in the cold air duct 5. The rear part of the internal circulation air duct 7 is connected to the cold air duct 5 through the combined air conditioning unit 6. The exhaust ports 8 are distributed on the side end of the internal exhaust air duct 2 of the cabinet. The double-layer louvered air hood 9 is installed at the exhaust port 8. The filter element 10 is installed inside the double-layer louvered air hood 9.

[0015] The internal circulation air duct 7 includes an air duct 11, a damper 12, an air inlet 13, and a circulation air outlet 14. The damper 12 is installed at the rear of the air duct 11, and the damper 12 is connected to the cold air duct 5. The air inlet 13 is opened at the front of the air duct 11, and a double-layer louvered air hood 9 is installed at the air inlet 13. The circulation air outlet 14 is opened at the rear of the air duct 11, and the air duct 11 is connected to the packaged air handling unit 6 through the circulation air outlet 14.

[0016] The air inlet 13 and the air outlet 8 are both inside the substation to form a circulating air flow.

[0017] The circulating air volume of the air inlet 13 is less than the exhausted air volume of the cabinet internal exhaust air duct 2.

[0018] The working principle of the present utility model: The air supply unit 4 takes air in a clean environment, sends the natural air into the cabinet internal exhaust air duct 2 in the substation through the external air duct 1 of the cabinet, and discharges it after being filtered by the filter element in the double-layer louvered air hood 9, so as to cool the overall environment in the substation. The direct ventilation tube 3 directly supplies air to heat sources such as inverters to accelerate the cooling of the equipment. The exhausted air is directly discharged through the door gap to prevent dust from entering. When it is necessary to supply cold air, the damper 12 and the packaged air handling unit 6 are opened, so that the internal circulation air duct 7 and the cold air duct 5 are connected to the external air duct 1 of the cabinet. The air in the substation enters through the air inlet 13, and after being filtered by the filter element in the double-layer louvered air hood 9, it enters the packaged air handling unit 6 through the internal circulation air duct 7. The cooled air enters the circulation through the external air duct 1 of the cabinet. The air supply volume is higher than the exhaust volume, so that the inside of the substation presents a positive pressure state, and the air at parts such as the door gap goes outwards, and external dust cannot enter, playing a role in dust prevention.

[0019] The above is the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principle and spirit of the present utility model, the changes, modifications, substitutions and variations made to the implementation manners still fall within the protection scope of the present utility model.
