Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: 1-3, an explosion-proof automatically controlled cabinet, including the cabinet body 1, the front of the cabinet body 1 is provided with cabinet door 2, is provided with sealed pad between cabinet body 1 and the cabinet door 2 and makes and has good leakproofness between the two, the bottom of the cabinet body 1 is provided with a plurality of sealed line cover 11 for pass the cable, can realize sealedly between cable and the sealed line cover 11. The inner wall of cabinet body 1 one side is provided with vertical induced draft channel 4 and return air passageway 5 side by side, and the lateral wall of cabinet body 1 has constituted the outer wall of induced draft channel 4 and return air passageway 5, the inner wall of cabinet body 1 opposite side is provided with vertical air-out passageway 6, and the lateral wall of cabinet body 1 has constituted the outer wall of air-out passageway 6, the lower extreme intercommunication of induced draft channel 4 and return air passageway 5, the other end of induced draft channel 4 extends to the middle part of the inner wall at cabinet body 1 top and this end is provided with air intake 41, the return air passageway 5 extends to the opposite side of the inner wall at cabinet body 1 top and communicates with the top of air-out passageway 6, the inboard of air-out passageway 6 lower part is provided with the air outlet, air outlet department is provided with fan 7. When the fan 7 rotates, hot air at the top of the electric control cabinet enters the air suction channel 4 from the air inlet 41, and then is blown out of the fan 7 through the air return channel 5 and the air outlet channel 6 in sequence, and in the process, heat in the hot air can be dissipated into the air of the outside through the side wall and the top wall of the electric control cabinet. The top wall and the two side walls of the structure can play a good role in heat dissipation. If the air in the electric control cabinet does not flow, heat tends to rise and accumulate at the top of the electric control cabinet, because the effect of heat dissipation is related to the difference between the inside and outside temperatures, only the top wall has a good heat dissipation effect, while the two side walls have a smaller heat dissipation effect.
Further, the size of the air outlet channel 6 in the front-rear direction of the cabinet body 1 is larger than the size of the air return channel 5 positioned on the side wall of the cabinet body 1 in the front-rear direction of the cabinet body 1, and the size of the air outlet channel 6 in the left-right direction of the cabinet body 1 is smaller than the size of the air return channel 5 positioned on the side wall of the cabinet body 1 in the left-right direction of the cabinet body 1, so that the air outlet channel 6 occupies a smaller space in the left-right direction of the cabinet body 1.
Furthermore, a plurality of fins 3 are arranged on the two sides and the top of the outer part of the cabinet body 1, and gaps are reserved among the fins 3, so that the heat dissipation capacity of the electric control cabinet is further improved. The fins 3 on the two sides of the cabinet body 1 are in a vertical state, dust is not easy to accumulate, and the heat radiation performance can be affected if the dust is thicker.
Further, the thickness of the fins 3 at the two sides of the outer part of the cabinet body 1 gradually narrows from top to bottom, so that the side surfaces of the fins 3 incline inwards in the direction from top to bottom, and the structure is more difficult to accumulate ash.
In operation, hot air is sucked from the air inlet 41 and finally blown out from the fan 7, and during this process, most of the heat in the hot air is dissipated to the outside air through the side walls and the top wall of the electric control cabinet, so as to avoid excessively high temperature rise caused by heat accumulation in the electric control cabinet.
