Every air outlet 15 department all is provided with a set of ventilating board 7 and aviation baffle 8, be provided with first pivot 9 on the side of air outlet 15, first pivot 9 sets up the side that is close to induced air duct 2 at air outlet 15, first pivot 9 sets up on the side of air outlet 15 perpendicular to cross wind channel 4 axis direction, the one end of first pivot 9 is connected with first steering wheel 10, fixedly connected with ventilating board 7 on the first pivot 9, ventilating board 7 can cover air outlet 15 completely, first steering wheel 10 can drive ventilating board 7 and rotate the completion to the opening and closing action of air outlet 15, ventilating board 7 rotates downwards and opens, so ventilating board 7 opens the back and can stretch downwards to cross wind channel 4 internal slant, has certain guide effect when the air current flows.

The air outlet 15 is provided with a second rotating shaft 11 below one side opposite to the first rotating shaft 9, the second rotating shaft 11 is rotatably connected with two side walls of the transverse air duct 4 in the horizontal direction through a rolling bearing, the air deflector 8 is fixedly connected to the second rotating shaft 11, the length direction of the air deflector 8 is arranged along the axis direction of the second rotating shaft 11, one end of the second rotating shaft 11 is connected with a second steering engine 12, and the second steering engine 12 can drive the second rotating shaft 11 to rotate so as to drive the air deflector 8 to rotate. The second rotating shaft 11 is arranged at the bottom of the cross air duct 4 in the height direction.

There are several modes when the cabinet is in operation,

1. the independent draught fan works, negative pressure is formed in the draught duct 2 to drive air in the transverse air duct 4 to flow, and the rotating ventilating plate 7 can be selected to open and close the air outlet 15. The air outlets 15 at different positions can be opened according to the situation, for example, the air outlets 15 around the equipment with higher temperature can be opened. Use the air conditioner to dispel the heat to the cabinet body 1 inside when ambient temperature is lower winter to the resource waste volume great, can use this kind of scheme when equipment calorific capacity is less, siphons away the hotter gas near the source of generating heat through air outlet 15 to form certain air flow velocity, cool down the source of generating heat. The air deflector 8 should be horizontal.

2. The induced draft fan and the cabinet air conditioner work simultaneously, and the rotation of the ventilation board 7 is controlled to enable the air outlet 15 to be in a closed state. At this moment, the cabinet air conditioner is opened and sends cold air into the air supply duct 3, and the induced draft fan works simultaneously. At this moment, cold air in the air supply duct 3 can enter the air guide duct 2 through the transverse air duct 4, and heat exchange is carried out through the air supply duct 3, the transverse air duct 4 and the side wall of the air guide duct 2, so that the temperature of air in the cabinet is cooled. The air deflector 8 can be in a horizontal state at this time. If the heat exchange efficiency of a certain section of transverse air duct 4 needs to be increased, the second steering engine 12 can be controlled to enable the air deflector 8 to be in a tilting state. The cross section of the transverse air duct 4 is reduced due to the tilting of the air deflector 8, and the heat on the side wall of the transverse air duct 4 can be taken away more due to the increase of the flow speed. One second steering engine 12 can be controlled independently, so that the section of a certain position of the transverse air duct 4 is reduced, and the heat exchange efficiency at the position can be improved. Different second steering engines 12 can be selectively controlled to work according to the calorific value of actual equipment, and the heat exchange efficiency is improved for a certain specific position.

3. The cabinet air conditioner works simultaneously, the induced draft fan does not work, and the rotation of the ventilation board 7 is controlled to enable the air outlet 15 to be in an open state. At this time, the cabinet air conditioner is opened and sends cold air into the air supply duct 3, and the cold air flows into the cabinet body 1 from the air outlet 15. Because the ventilating board 7 will extend downwards and slantways into the transverse air duct 4 after being opened, and the end of the ventilating board 7 which is opened is the end close to the air supply duct 3. Thus, an inclined guide plate is formed, the airflow from the air supply duct 3 can smoothly flow out of the air outlet 15 from the ventilating plate 7 under the action of the ventilating plate 7, and a large amount of low-temperature air can flow to a device to be radiated. The air deflector 8 should be horizontal.

4. The cabinet air conditioner works simultaneously, the induced draft fan does not work, the rotation of the ventilating plate 7 and the air deflector 8 at a certain air outlet 15 is controlled to enable the air outlet 15 to be in an open state, and the air deflector 8 is lifted upwards. At this time, the cabinet air conditioner is opened and sends cold air into the air supply duct 3, and the cold air flows into the cabinet 1 from the air outlet 15. Because the ventilating plate 7 can extend downwards in the transverse air duct 4 after being opened, the opened end of the ventilating plate 7 is the end close to the air supply duct 3, and the air deflector 8 is lifted upwards. Like this ventilation board 7 and aviation baffle 8 can basically cover cross-wind channel 4 cross-section completely, and whole cross-wind channel 4 only can have a set of ventilation board 7 and aviation baffle 8 this moment, and the air current that comes from supply air duct 3 can be more smooth and easy to flow out air outlet 15 from ventilation board 7 under the effect of ventilation board 7 and aviation baffle 8, and a large amount of low temperature air can flow to by radiating device like this.

Different heating conditions in the cabinet can be adapted through different working modes. The first scheme is used when the device generates less heat when the ambient temperature is low. The second scheme is used when the device generates less heat when the ambient temperature is high. The third scheme is used when the device generates a higher amount of heat. When a certain device has huge heat productivity in a short time, the fourth scheme is used, and the device can be cooled in a targeted manner.
