In addition, the guide plate arranged in the vertical direction can ensure that the guided wind keeps moving upwards in the area, and the consistency of the wind quantity of each area is also ensured. Consequently, also can the heat dissipation even under the condition of fan damage of switch board of this application.
Drawings
Fig. 1 is a schematic diagram of a power distribution cabinet according to the present application.
The air conditioner comprises a cabinet body 1, a guide plate 101, a flow distribution plate 102, a check plate 2 and a fan 3.
Detailed Description
The technical solutions in the embodiments shown in the present application will be clearly and completely described below with reference to the drawings in the embodiments shown in the present application.
Referring to fig. 1, a power distribution cabinet includes a cabinet body 1, a check plate 2 and a fan 3; the check plate 2 is positioned between the cabinet body 1 and the fan 3, and the check plate 2 is used for preventing the wind which is blown into the cabinet body 1 by the fan 3 from flowing back; a plurality of guide plates 101 in the vertical direction are arranged in the cabinet body 1, a flow distribution plate 102 is arranged below the guide plates 101, and a control unit is also arranged in the cabinet body 1; one end of the diverter plate 102 is rotatable around this other end remote from the deflector plate 101; at least more than two fans 3 are arranged; when one of the fans 3 is damaged, the control unit rotates the diversion plate 102 to divert a part of the wind from the other fans 3 to the area, and blows the wind into the cabinet 1 through the diversion plate 101.
Therefore, when one of the fans 3 is damaged, the control unit is started, the control unit controls the splitter plate 102 to guide the wind in the other area to the area, and the wind volume in the area is supplemented. In addition, the guide plate 101 arranged in the vertical direction can ensure that the guided wind keeps moving upwards in the area and also ensures the consistency of the wind quantity of each area. Consequently, the switch board of this application also can the heat dissipation even under the condition of fan damage.
An air volume detector is arranged between two adjacent guide plates 101, and the rotation angle of the guide plates 101 is controlled according to the air volume detected in each area, so that the difference value of the air volume in each area is smaller than a preset threshold value. The air quantity value detected by the air quantity detector is transmitted to the control unit, the control unit controls the guide plate 101 to rotate, the air quantity detector detects the air quantity in real time and transmits the air quantity value to the control unit in real time, the control unit compares the received air quantity values of all the regions, and when the difference value between the air quantities is smaller than a threshold value, the control unit controls the guide plate 101 to stop rotating.
Each fan 3 is provided with a rotation speed sensor, and a signal detected by the rotation speed sensor is transmitted to the control unit, and the control unit controls the rotation angle of the splitter plate 102 according to data fed back by the air volume detector. When each splitter plate 102 can rotate independently, the air volume of each area can be controlled independently, which is more beneficial to the distribution of the air volume of each area, and ensures that the air volume of each area can be uniform and consistent.
Each flow distribution plate 102 independently rotates, when the fan 3 in a certain area is broken down, the flow distribution plate 102 in the area directly rotates to the horizontal position, the rotation angle of the fan 3 in the adjacent area is large, the air volume in the area is supplemented, the rotation of other areas is small, the air volume in the adjacent area is supplemented, and the air volume in each area is large, uniform and consistent. After the fan 3 in a certain area is broken down, the air volume in the area is almost 0 due to the existence of the guide plate 101, so the splitter plate 102 in the area is directly rotated to the horizontal position, the opening of the area is kept to be the largest, meanwhile, the rotation angle of the fan 3 in the adjacent area is large, the air volume in the area is supplemented at the fastest speed, and the equipment is prevented from being burnt out.
To sum up, the switch board of this application also can dispel the heat evenly under the condition of fan damage, possesses the characteristics that control is simple, the amount of wind distribution is quick even simultaneously.
