The draft duct 2 is a vertical rectangular tubular structure. The top of the draft duct 2 protrudes from the cabinet and is provided with an induced draft fan. The gas in the air duct 4 moves to the induced air duct 2 under the action of pressure.

The air supply duct 3 is a vertical rectangular tubular structure. The top of the air supply duct 3 extends out of the cabinet and is provided with a cabinet air conditioner. The cabinet air conditioner can blow low-temperature air into the air supply duct 3, and can make the The inside of the air supply duct 3 is in a positive pressure state, so that the low-temperature air can be pressed into the cross air duct 4 .

The cross air duct 4 includes an air duct wall 5, a support beam 6, a ventilation plate 7 and an air guide plate 8. The air duct wall 5 of the cross air duct 4 is a square tubular structure, and the top of the air duct wall 5 is provided with a Air outlet 15, the air outlet 15 is evenly arranged along the axial direction of the transverse air duct 4, the spacing of the air outlet 15 is 40mm, the width of the air outlet 15 is 35mm, the air outlet 15 is a rectangular hole, the The air outlet 15 extends along the front and rear directions of the cabinet and runs through the top surface of the entire cross air duct 4. The support beam 6 is arranged on the outside of the air duct wall 5 between two adjacent air outlets 15. The support beam 6 It is a square tube-mounted structure, and the support beam 6 is a rectangular cold-drawn aluminum tube, which can maintain good thermal conductivity, and can effectively reduce the structural weight compared with the integral rod. The support beam 6 is used to install electrical equipment.

Each air outlet 15 is provided with a set of ventilation plates 7 and air guide plates 8 , and a first rotating shaft 9 is disposed on one side of the air outlet 15 , and the first rotating shaft 9 is disposed near the air outlet 15 . On one side of the air duct 2, the first rotating shaft 9 is arranged on the side of the air outlet 15 perpendicular to the axis direction of the transverse air duct 4, and one end of the first rotating shaft 9 is connected with the first steering gear 10, A ventilation plate 7 is fixedly connected to a rotating shaft 9. The ventilation plate 7 can completely cover the air outlet 15. The first steering gear 10 can drive the ventilation plate 7 to rotate to complete the opening and closing of the air outlet 15. 7 is turned downward to open, so the ventilation plate 7 will extend downward obliquely in the transverse air duct 4 after it is opened, and there will be a certain guiding effect when the air flows through.

Below the side of the air outlet 15 opposite to the first rotating shaft 9, a second rotating shaft 11 is arranged, and the second rotating shaft 11 is rotatably connected to the horizontal two side walls of the transverse air duct 4 through rolling bearings, and the air guide plate 8 is fixed. Connected to the second rotating shaft 11, the length direction of the wind 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 gear 12, the second steering gear 12 The second rotating shaft 11 can be driven to rotate, thereby driving the wind deflector 8 to rotate. The second rotating shaft 11 is arranged at the bottom of the transverse air duct 4 in the height direction.

When the cabinet works, there are the following modes:

1. The induced draft fan works alone, and the negative pressure formed in the draft duct 2 drives the air flow in the cross-air duct 4. At this time, the rotating ventilation plate 7 can be selected to open and close the air outlet 15. The air outlet 15 at different positions can be opened according to the situation, for example, the air outlet 15 around the device with higher temperature can be opened. In winter, when the ambient temperature is low, using the air conditioner to dissipate heat inside the cabinet 1 will waste a large amount of resources. This solution can be used when the heat generated by the equipment is small, and the hot gas near the heat source is sucked away through the air outlet 15. , and form a certain air flow speed to cool down the heat source. The wind deflector 8 should be in a horizontal state.

2. The induced draft fan and the cabinet air conditioner work at the same time, and the rotation of the ventilation plate 7 is controlled to keep the air outlet 15 in a closed state. At this time, the cabinet air conditioner will be turned on and the cold air will be sent into the air supply duct 3, and the induced draft fan will work at the same time. At this time, the cold air in the air supply duct 3 will enter the induced air duct 2 through the horizontal air duct 4, and conduct heat exchange through the air supply duct 3, the horizontal air duct 4 and the side walls of the induced air duct 2, thereby cooling the gas temperature in the cabinet. . At this time, the wind deflector 8 may be in a horizontal state. If it is necessary to increase the heat exchange efficiency of a certain section of the cross air duct 4, the second steering gear 12 can be controlled so that the wind deflector 8 is in a tilted state. The uplift of the wind deflector 8 makes the cross-section of the cross-air duct 4 smaller, and the increased flow velocity here can take away more heat from the side wall of the cross-air duct 4 . A certain second steering gear 12 can be controlled independently to reduce the cross-section of a certain position of the cross-air duct 4, so that the heat exchange efficiency here will be increased. In this way, different second steering gears 12 can be selectively controlled to work according to the actual heat generated by the equipment, and the heat exchange efficiency can be improved for a specific position.

3. The cabinet air conditioner works at the same time, the induced draft fan does not work, and the rotation of the ventilation plate 7 is controlled to keep the air outlet 15 in an open state. At this time, the cabinet air conditioner will be turned on and the cold air will be sent into the air supply duct 3, and the cold air will flow from the air outlet 15 to the inside of the cabinet 1. Because the ventilation plate 7 will extend diagonally downward into the transverse air duct 4 after it is opened, and the open end of the ventilation plate 7 is the end close to the air supply duct 3 . In this way, an inclined guide plate is formed, and the air flow from the air supply duct 3 will flow out of the air outlet 15 relatively smoothly from the ventilation plate 7 under the action of the ventilation plate 7, so that a large amount of low-temperature air can flow to the device to be radiated. The wind deflector 8 should be in a horizontal state.

4. The cabinet air conditioner works at the same time, and the induced draft fan does not work. Control the rotation of the ventilation plate 7 and the air deflector 8 at a certain air outlet 15 so that the air outlet 15 is in an open state, and the air deflector 8 is lifted upwards. At this time, the cabinet air conditioner will be turned on and the cold air will be sent into the air supply duct 3 , and the cold air will flow into the cabinet body 1 from the air outlet 15 . The open end of the ventilation plate 7 is close to the end of the air supply duct 3, and the air deflector 8 is lifted upwards. In this way, the ventilation plate 7 and the air guide plate 8 will basically completely cover the cross section of the cross air duct 4. At this time, the entire cross air duct 4 can only have one set of the ventilation plate 7 and the air guide plate 8, and the air flow from the air supply duct 3 will be ventilated. Under the action of the plate 7 and the air guide plate 8, the airflow will flow out of the air outlet 15 from the ventilation plate 7 relatively smoothly, so that a large amount of low-temperature air can flow to the device to be radiated.

Different heating conditions in the cabinet can be adapted through different working modes. When the ambient temperature is low, the device generates a small amount of heat, and the first solution is used. Use the second solution when the ambient temperature is high and the heat generated by the device is small. The third option is used when the device generates high heat. When a device generates a huge amount of heat in a short time, the fourth solution can be used to cool the device in a targeted manner.
