Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling spraying, and in particular relates to a liquid cooling spraying device for a data center cabinet. Background Art

[0002] Data centers are global collaborative networks of specific equipment used to transmit, accelerate, display, calculate and store data information on the internet network infrastructure. With the rapid growth of social economy, the development and construction of data centers will be in a high-speed period, and there will be more and more large data centers. In the layout and construction of data centers, cabinets are an indispensable part of electrical equipment and the carrier of electrical control equipment. They are mainly used to accommodate electrical or electronic equipment.

[0003] The energy consumption of data centers is generally high, especially for data center server equipment that runs uninterruptedly throughout the year. In order to ensure the safe, stable and continuous operation of the data center, the data center cabinets need to be cooled and cooled. Currently, the common cooling methods for data center cabinets are mainly: air cooling and liquid cooling. Among them, liquid cooling is further divided into immersion liquid cooling, liquid cooling plate cooling and spray liquid cooling.

[0004] Spraying liquid cooling mainly guides the coolant to the surface of the heat source in a spraying manner, and cools the heat source by exchanging heat between the coolant and the heat source, thereby reducing the temperature of the equipment. Most of the liquid cooling spray mechanisms in the prior art do not have the function of filtering impurities, and only use centralized filtering and cooling to process the coolant after heat exchange. This method has a poor effect on filtering impurities in the coolant, so that some impurities will exist in the circulating coolant. These impurities will not only clog the spray components of the liquid cooling spray device, but also damage the heat source, making the spray reliability of the liquid cooling spray device poor.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, a liquid cooling spray device for a data center cabinet in one embodiment of the utility model includes: a cabinet body 1, a self-filtering spray component 2, and a filtering reflux component 3.

[0030] like Figures 2 to 3 As shown, the self-filtering spray assembly 2 is fixedly assembled in the cabinet 1, and the self-filtering spray assembly 2 includes a spray plate 201, and the spray plate 201 is fixedly mounted above the cabinet 1. The spray plate 201 is used to assemble and conduct multiple groups of spray nozzles 208.

[0031] Specifically, the spray plate 201 is hollow, and the spray plate 201 is connected to the liquid inlet pipe 202. By making the spray plate 201 hollow, it is convenient to provide the cooling liquid required for spraying to the plurality of spray nozzles 208.

[0032] like Figures 2 to 3 As shown, a plurality of spray nozzles 208 are threadedly mounted below the spray plate 201. The plurality of spray nozzles 208 are convenient for spraying cooling liquid onto the surface of the heat source, thereby spraying the cooling liquid onto the heat source.

[0033] like Figure 3 to Figure 4As shown, a liquid inlet pipe 202 is fixedly connected to one side of the spray plate 201. The liquid inlet pipe 202 is used to transport the cooling liquid required for liquid cooling spraying into the spray plate 201. A conducting cylinder 203 is fixedly installed on the side of the liquid inlet pipe 202 away from the spray plate 201. The conducting cylinder 203 assembles and fixes the fixed end cover 204 and the filter cartridge 205, and provides a filtering space for the cooling liquid transported by the liquid adding pipe 207.

[0034] like Figure 3 to Figure 4 As shown, a conducting tube 209 is connected between the liquid inlet tube 202 and the conducting cylinder 203. The conducting tube 209 serves to connect the conducting cylinder 203 and the liquid inlet tube 202. By removing and separating the conducting tube 209 from the liquid inlet tube 202, the conducting cylinder 203 can be easily disassembled and assembled independently.

[0035] like Figure 3 to Figure 4 As shown, the bottom of the conduction cylinder 203 is threadedly connected with a fixed end cap 204. The fixed end cap 204 supports and fixes the filter cartridge 205, and the filter cartridge 205 can be conveniently disassembled and assembled by threading the fixed end cap 204, thereby improving the convenience of cleaning, disassembly, assembly and maintenance of the filter cartridge 205.

[0036] like Figure 3 to Figure 4 As shown, a filter cartridge 205 is fixedly connected to one side of the fixed end cap 204 located in the conducting cylinder 203. It is convenient to filter impurities from the coolant transported by the liquid adding pipe 207 through the filter cartridge 205.

[0037] like Figure 3 to Figure 4 As shown, a cylinder cover 206 is fixedly installed above the conduction cylinder 203. The cylinder cover 206 cooperates with the conduction cylinder 203 to form a closed filter cylinder, which provides space for filtering impurities in the coolant.

[0038] like Figure 3 to Figure 4 As shown, a liquid adding pipe 207 is fixedly connected to the top of the cartridge cover 206, and the liquid adding pipe 207 is arranged in cooperation with the filter cartridge 205. It is convenient to transport the cooling liquid into the filter cartridge 205 through the liquid adding pipe 207.

[0039] like Figures 3 to 6 As shown, a limit frame 210 is fixedly installed in the liquid adding pipe 207. The limit frame 210 plays a role of assembly limit for the driving shaft 211.

[0040] like Figure 3 to Figure 4 As shown, a driving shaft 211 is rotatably connected inside the limiting frame 210. The driving shaft 211 supports and fixes the fixing frame 213 and performs rotational driving.

[0041] like Figure 3 to Figure 4As shown, one end of the driving shaft 211 located in the liquid adding pipe 207 is fixedly connected with a driving impeller 212. The driving shaft 211 is conveniently driven to rotate by the driving impeller 212 rotating under the action of the coolant.

[0042] like Figure 3 to Figure 4 As shown, one end of the driving shaft 211 located in the filter cartridge 205 is fixedly connected to a plurality of sets of fixing frames 213. The fixing frames 213 serve to connect the cleaning plate 214 and the driving shaft 211.

[0043] like Figure 3 to Figure 4 As shown, one end of the plurality of fixing frames 213 away from the driving shaft 211 is fixedly connected with a cleaning plate 214. The cleaning plate 214 supports and fixes the cleaning brush 215 and allows it to rotate synchronously.

[0044] like Figure 3 to Figure 4 As shown, a cleaning brush 215 is fixedly connected to one side of the cleaning plate 214 away from the fixing frame 213, and the cleaning brush 215 is arranged in cooperation with the filter cartridge 205. The rotation of the cleaning brush 215 can scrub the inner wall of the filter cartridge 205, thereby reducing the clogging of the filter cartridge 205 and improving the filtering and circulation effect of the filter cartridge 205.

[0045] like Figures 2 to 5 As shown, the filter reflux assembly 3 is fixedly assembled in the cabinet 1, and the filter reflux assembly 3 includes a liquid collecting tray 301, and the liquid collecting tray 301 is fixedly assembled below the spray plate 201. The coolant sprayed by the multiple groups of spray nozzles 208 is filtered and refluxed through the liquid collecting tray 301.

[0046] like Figures 3 to 5 As shown, a return pipe 304 is fixedly connected to one side of the liquid collecting pan 301. The return pipe 304 is used to return the cooling liquid collected by the liquid collecting pan 301 after heat exchange.

[0047] like Figure 2 As shown, a supporting plate 302 is fixedly installed in the liquid collecting tray 301. The supporting plate 302 supports the components or other parts in the cabinet 1.

[0048] like Figure 2 As shown, a plurality of evenly distributed fixed angle pieces 305 are fixedly connected between the support plate 302 and the liquid collecting tray 301. The fixed angle pieces 305 play the role of connecting the support plate 302 and the liquid collecting tray 301, so as to facilitate the assembly and fixation of the support plate 302.

[0049] like Figures 3 to 5 As shown, multiple groups of uniformly distributed filter boxes 303 are fixedly connected to the outer side of the support plate 302. The multiple groups of filter boxes 303 are used to filter the collected coolant after heat exchange.

[0050] like Figures 3 to 5 As shown, a filter screen 306 is fixedly installed in each of the plurality of liquid collecting trays 301, and the level of the filter screen 306 is lower than the level of the upper surface of the liquid collecting tray 301. The filter screen 306 performs preliminary filtration on the coolant collected in the liquid collecting tray 301 after heat exchange.

[0051] During specific use, the coolant with a lower temperature is transported to the conductive cylinder 203 along the liquid adding pipe 207, filtered by the filter cylinder 205, and then transported to the spray plate 201 along the conductive pipe 209 and the liquid inlet pipe 202, and sprayed onto the surface of the heat source by multiple groups of spray nozzles 208, so as to cool and dissipate the heat source through heat exchange of the coolant.

[0052] At the same time, when the coolant is transported along the filling pipe 207, the driving impeller 212 will drive the driving shaft 211 to rotate with the flow of the coolant, and the rotation of the driving shaft 211 will drive a pair of cleaning plates 214 and cleaning brushes 215 to rotate, thereby achieving the purpose of uninterrupted brushing of the inner wall of the filter cartridge 205, thereby improving the efficiency of the filter cartridge 205 in heat exchange with the coolant.

[0053] In addition, the coolant after heat exchange can be collected by the collecting tray 301, and the coolant collected by the collecting tray 301 can be discharged from the return pipe 304 after filtering and removing impurities through the filter box 303 and the filter net 306. By filtering and removing impurities from the coolant transported to the spray plate 201, the possibility of impurities clogging the spray nozzle 208 and damaging the heat source components is reduced, thereby improving the reliability of the liquid cooling spray device.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
