In one example, as shown in fig. 1, the cabinet 10 may include a first electric air valve 101, an exhaust fan 102, a second electric air valve 103, a blower 104, an air conditioning terminal 105, a return air passage 106, and a supply air passage 107.

The return air duct 106 may be disposed at the back of the cabinet 10, and the supply air duct 107 may be disposed at the front of the cabinet. For example, it may be provided on the door frame side of the cabinet 10.

In one possible design, the supply air duct 107 may be provided with one or more air outlets. The opening direction of the one or more air outlets is inside the cabinet.

The exhaust fan 102 is disposed at the upper port of the return air channel 106 and located outside the top of the cabinet 10. The first electric damper 101 is disposed above the exhaust fan 102.

It should be noted that, when the first electric air flap 101 is in the closed state, the first electric air flap 101 and the exhaust fan 102 may be in a closed space. In this manner, external dust can be prevented from entering the inside of the cabinet 10.

Further, in order to prevent foreign matters such as dust in the air from entering the cabinet 10 when the first electric air valve 101 and the exhaust fan 102 are in the open state, an air filtering device may be further provided at the upper port of the return air duct 106. The air filtering device may be disposed below the exhaust fan 102, or may be disposed between the exhaust fan 102 and the first electric damper 101.

The blower 104 is disposed at a lower end of the blower passage 107 and is located outside the bottom of the cabinet 10. The second electric damper 103 is provided below the blower 104.

It should be noted that, when the second electric air valve 103 is in the closed state, the second electric air valve 103 and the blower 104 may be in a closed space. In this manner, external dust can be prevented from entering the inside of the cabinet 10.

Further, in order to prevent foreign matters such as dust in the air from entering the cabinet 10 when the second electric air valve 103 and the blower 104 are in the on state, an air filtering device may be provided at an upper port of the return air duct 106. The air filter device may be disposed below the blower 104, or may be disposed between the blower 104 and the second electric air valve 103.

It should be pointed out that, set up electronic blast gate and fan in the rack outside based on the aforesaid, can be convenient for maintainer maintains electronic blast gate and fan.

Wherein the air conditioner terminal 105 may be disposed at the bottom of the cabinet 10. The air conditioning tip 105 is oriented upward. In this manner, the cool air generated by the air conditioning terminal 105 may blow directly to the equipment within the cabinet 10, thereby reducing the temperature of the equipment.

In one possible design, as shown in fig. 2, the air conditioning tip 105 may include an EC blower 1051, a surface cooler 1052. Of course, the air conditioning terminal 105 may also include other devices, such as a refrigerant line, a control valve, etc. Without limitation.

Further, a partition plate may be disposed between the air conditioning terminal 105 and the equipment of the cabinet 10. The partition plate may be provided with a plurality of apertures. In this way, the installation of the equipment is facilitated, and the cold air generated by the air conditioning terminal 105 is not influenced to enter the inside of the cabinet 10.

In one possible design, when the air conditioner terminal 105 cannot cool, for example, the surface cooler 1052 is damaged, the first electric air valve 101, the exhaust fan 102, the second electric air valve 103, and the blower 104 are in the open state. As shown in fig. 2, the blower 104 may send cool air outside the cabinet 10 into the blower passage 106 to lower the temperature of the equipment inside the cabinet 10. The exhaust fan 102 may discharge the hot air inside the cabinet 10 to the outside of the cabinet 10 through the return air passage 106. As such, by increasing the air circulation flow, the temperature of the equipment within the cabinet 10 may be reduced over a course.

Further, a refrigeration device may be disposed in the machine room where the cabinet 10 is located. In the case where the air conditioning end 105 of the cabinet 10 is normal, the refrigeration equipment may be in an off state; in the event that the air conditioning end 105 of the cabinet 10 is unable to cool, the cooling device is in an open state. In this manner, the temperature of the air outside the cabinet 10 may be reduced.

Based on this design, through the combined operation of the refrigeration plant of the outside of rack and the electronic blast gate and the fan of rack, can send into the rack inside with the outside cold air of rack to can reduce the temperature of the equipment in the rack.

In one possible design, as shown in fig. 1, the bottom of the cabinet 10 may also be provided with an overhead floor 108. The hollow layer 108 is hollow around. So can guarantee air cycle at electronic blast gate and fan during operation.
