[0034] Such as figure 1 and figure 2 As shown, a data center downflow air conditioner 10 includes an air conditioner casing 11 , a surface cooler 12 , an EC fan 13 , a bottom air supply module 14 , and a drainage channel 15 . The bottom air supply module is composed of a bracket 16 , a bottom air supply channel 17 , an orifice 18 , a ventilation floor 19 , a closed plate 20 , an air guiding orifice 21 and a drainage channel 15 arranged below the orifice 18 . figure 1 Among them, the drainage channel 15 is a dotted line part, which is distributed under the orifice plate 18, specifically as figure 2 shown. The EC fan 13 is a large impeller fan, and is arranged in the bracket 16 below the air conditioner casing 11 . In this embodiment, by disposing the EC fan under the housing of the inter-row air conditioner, the air blowing from the air conditioner is realized, and the blowing efficiency of the fan is high. Moreover, the EC fan is arranged under the shell of the inter-row...

[0041] The difference between the second embodiment and the first embodiment is that the surface cooler 12 is a longitudinal finned tube heat exchanger, and the flow of cold water and air in the surface cooler is in a reverse flow mode, such as Figure 4 shown. In this case, the longitudinal finned tube heat exchanger occupies most of the space of the air conditioner shell, the contact area between the gas and the heat exchanger in the heat exchanger is large and the stroke is long, and the gas flow and liquid flow are in a countercurrent mode, which means The heat exchange efficiency of the cooler 12 is higher than that of common surface coolers, and the cooling efficiency of the inter-row air conditioner is higher.

[0043] Such as Figure 5 , figure 1 , figure 2As shown in the figure, a data center downflow air-conditioning cooling system includes several down-flow air conditioners 10, several cabinets 24, cold aisles, and hot aisles. The inter-row air conditioners 10 and cabinets 24 are arranged in a straight line The cabinets are arranged in a row to form a cabinet group, and the cabinet groups are distributed in the data center. The downflow inter-row air conditioner 10 includes an air conditioner casing 11 , a surface cooler 12 , an EC fan 13 , a bottom air supply module 14 , and a drainage channel 15 . The bottom air supply module 14 is composed of a bracket 16 , a bottom air supply channel 17 , a perforated plate 18 , a ventilated floor 19 , a closed plate 20 and a drainage channel 15 arranged below the perforated plate 18 . The EC blower 13 is arranged inside the bottom air supply module 14 . The casing of the cabinet 24 and the inter-row air conditioner 10 is arranged on the ...

Abstract

The invention relates to a data center downside air supply inter-column air conditioner comprising an air conditioner shell, a surface air cooler, EC fans, a bottom air supply module and a drainage channel. The inter-column air conditioner is set as a downside air supply inter-column air conditioner, the floor is set as a ventilation floor, and a pore plate, an air guide pore plate and the drainage channel are arranged in a bottom air supply channel. Therefore, a single inter-column air conditioner has the advantages of high efficiency of cold air fans, large air volume, a small number of fans, no risk of water leakage, large space reserved for the surface air cooler in the air conditioner shell, and large refrigeration capacity.

Description

technical field [0001] The invention relates to the field of data center cooling systems, in particular to an air-conditioning and cooling system for down-supply air-rows in a data center. Background technique [0002] In the current conventional data center cooling system including inter-row air conditioners, the general inter-row air conditioners use the method of sending cold air from the front door and returning hot air from the rear door to circulate hot and cold air. In this case, in order to maintain the air supply effect, it is generally necessary to configure multiple units. Fan, this air supply method has low efficiency, high energy consumption of the fan, and will send the cold air containing dew directly into the cold aisle when the humidity of the cold air is high and condensation occurs. When there is other water leakage in the inter-row air conditioner, the leaked water will also flow out of the inter-row air conditioner with the cold air, which will bring har...
