Detailed ways

The present invention will be further described with reference to the following examples.

A specific implementation of a high-temperature rectification device for a single-silo cabinet of the present invention, the high-temperature rectification device in this embodiment is mainly used for the rectification of more than two single-silo cabinets. As shown in Figures 1 and 2, the high-temperature rectification device includes: Air inlet duct 3 , return air duct 4 , first single-silo cabinet 1 and second single-silo cabinet 2 . One end of the air inlet duct 3 is communicated with the first air inlet 31 opened at the upper part of the first single-silo cabinet 1, and the other end of the air inlet duct 3 is communicated with the second air inlet 32 opened at the upper part of the second single-silo cabinet 2. One end of the air duct 4 is communicated with the first air return port 41 opened at the lower part of the first single-silo cabinet 1 , and the other end of the return air duct 4 is communicated with the second air return port 42 opened at the lower part of the second single-silo cabinet 2 .

In this embodiment, the air conditioners of the first single-cabin cabinet 1 or/and the second single-cabinet cabinet 2 are installed above the cabinets, and the first air inlet 31 and the second air inlet 32 are correspondingly opened in the first single-cabinet cabinet The upper side of the backplane of 1 and the upper side of the backplane of the second single-chamber cabinet 2 are opened. The first air return port 41 and the second air return port 42 are correspondingly opened on the lower side of the backplane of the first single-cabinet cabinet 1 and on the lower side of the backplane of the second single-cabin cabinet 2 . This structure utilizes the principle that cold air sinks and hot air rises, and the rectification is carried out directly at the back panel of the cabinet, which is convenient for on-site workers to construct, reduces the labor intensity of workers, and shortens the construction time and rectification time.

In order to improve the gas flow rate, as shown in FIG. 2 , the air inlet duct 3 is fixedly installed with an air intake fan 6 for blowing hot air, and the return air duct 4 is fixedly installed with a return air fan 7 for blowing cold air. The fan is installed in the pipeline, and the pipeline can be directly inserted and fixed in the cabinet during rectification. Compared with the construction method of fixing the fan and the pipeline after opening the cabinet, it is not necessary to fasten the fan or pipeline on the cabinet, reducing the cost. The difficulty and working hours of rectification are reduced.

In order to further increase the gas flow rate, the air inlet fan 6 is installed at the air inlet end of the air inlet duct 3 . Similarly, the return air fan 7 is installed at the air inlet end of the return air duct 4, which can speed up the flow of gas in the single-silo cabinet. Of course, the air inlet fan 6 with the same upwind direction can also be installed at the air inlet end and the air outlet end of the air inlet duct 3. Similarly, it can also be installed at the air inlet end and the air outlet end of the return air duct 4. Return air fan 7 with the same upwind direction. In addition, the fan can also be installed at the air outlet end of the pipeline. At this time, the pipeline is suctioned by negative pressure. In view of the long pipeline length or the lack of air leakage at the pipeline connection, the conveying force provided by the fan Weak, the heat exchange efficiency of cold and hot air between the two cabinets is low.

When the air conditioner 5 is installed in the first single-silo cabinet 1 or the second single-storage cabinet 2, the air conditioner 5 in the single-silo cabinet installed with the air conditioner 5 discharges the low-temperature cold air after cooling down, and the cold air sinks. Under the pulling action of the fan 7, the cooling capacity is transported to the adjacent single-silo cabinet through the return air duct 4, and the hot air in the adjacent single-silo cabinet floats up, and returns through the air inlet passage under the pulling action of the air inlet fan 6. In the single-storage cabinet with the air conditioner 5 installed, the indoor side heat exchanger of the air conditioner 5 in the single-storage cabinet absorbs heat and converts the high-temperature hot air into low-temperature cold air, which is re-transported into the main cabinet, and the cold air sinks to complete the phase. The circulation of cold and hot air between two adjacent single-bay cabinets is organized. The air conditioner 5 uses the phase change of the refrigerant to transfer the heat in the adjacent cabinets to the outside of the cabinet, without the need to form direct heat exchange with the outside of the cabinet, which ensures the air cleanliness in the cabinet, and only one air conditioner 5 is required. The temperature control of two adjacent independent communication outdoor cabinets can be completed, which reduces the rectification cost. Compared with the traditional rectification device, the structure is simpler, and it can be applied to the rectification of two adjacent single-silo cabinets with a large interval. When both the first single-cabinet cabinet 1 and the second single-cabinet cabinet 2 are equipped with air conditioners 5, only the air conditioner 5 in one of the single-cabinet cabinets can be activated, and the air conditioner 5 in the other single-cabinet cabinet can be used as a backup air conditioner In use, the frequency of replacing the air conditioner 5 can be reduced.

In order to avoid heat exchange with the air outside the cabinet when the air flows through the air inlet duct 3 or the return air duct 4, the outer periphery of the air inlet duct 3 or/and the outer periphery of the return air duct 4 is covered with thermal insulation cotton. When the cabinet is installed outdoors, it can also protect the pipeline from rain, sun, and corrosion.

In this embodiment, see FIG. 3 , the air inlet duct 3 or/and the return air duct 4 are arranged in a U shape. The U-shaped setting is convenient for construction workers, takes up as little space as possible, and is simpler to install the fan. Specifically, please refer to Fig. 3. Taking the air inlet pipe 3 as an example, the pipe can be prepared by using existing mature components such as water pipes (straight pipe 81 and elbow 82), as well as sheet metal air ducts or telescopic pipes. (similar to the hood duct) and other connecting pipes instead. For the transformation between two cabinets with different intervals, it is only necessary to cut the straight pipes 81 of different lengths on site, and the straight pipes 81 and the elbows 82 can be spliced together to form a pipe. This structure is convenient for assembly and sealing, and ensures the rectification. of generality.

In this embodiment, the air inlet duct 3 is arranged in the upper part of the modified cabinet, because the upper part of the cabinet mainly circulates high-temperature hot air. In other embodiments, the heat is concentrated in the lower part of the cabinet or the air conditioner 5 is arranged in the cabinet. In the case of the lower part of the body, the positions of the air inlet duct 3 and the return air duct 4 can also be exchanged to ensure that the air inlet duct 3 can directly transport the high-temperature hot air to the indoor air inlet of the air conditioner 5 .

In addition, other channels may be arranged inside the cabinet to connect the indoor air inlet of the air conditioner 5 with the air inlet channel outlet to form a hot channel, and connect the indoor air outlet of the air conditioner 5 to the return air channel inlet to form a cold channel.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Persons should understand that the technical solutions of the present invention may be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
