Description

Technical Field

[0001] The present invention relates to a temperature monitoring optical fiber cable strand structure and a server rack system including the cable strand structure, and more particularly to a temperature monitoring optical fiber cable strand structure that can easily measure the temperatures of a plurality of components and a server rack system including the cable strand structure. Background Art

[0002] A server is a computer or software that provides services to other computers in a computer network.

[0003] In recent years, with the growth of Internet business, the increasing demand for cloud environments and mobile environments, the demand for servers and IDCs (Internet Data Centers) that are collections of multiple servers has also continued to increase.

[0004] Servers and IDCs require high configuration and high performance, so the heat generated during the driving process is also high. Therefore, in order to prevent the server and IDC from overheating, a cooling system is usually set up.

[0005] However, when a plurality of servers are assembled, such as an IDC that is a server assembly, only the physical number of servers and the power supply are considered, so the response to the heat generation of each server is limited. In particular, since the degree of heat generation of each server varies depending on its software and computing operations, it is difficult to proactively track and provide the best status for each server.

[0006] Therefore, for a server rack system that integrates a plurality of servers, it is necessary to develop a temperature monitoring optical fiber cable strand structure that can independently track heat generation and actively respond to it, and a server rack system including the cable strand structure.

[0007] Korean Patent Publication No. 10-1865151 discloses a system for monitoring the internal temperature of a server, and more specifically, discloses a system for monitoring the internal temperature and power consumption of a server and adjusting the temperature of the server accordingly.

[0008] However, in such servers, the temperature of a specific location in the server room is directly measured by the manager, so there is a limitation in measuring the temperature of each server. In addition, there is a possibility of error due to human error during the temperature measurement process.

[0009] Korean Patent Gazette No. 10-2368592 discloses a temperature simulation modeling method for a data sensor server room. Specifically, the method improves reliability by comparing the actually measured temperature of the server room with the CFD (Computational Fluid Dynamics) simulation result.

[0010] However, this method can only measure the temperature of a specific location in the server room, so it is difficult to collect the temperature information of each server. In other words, it is difficult to collect the accurate heat generation of each server. Summary of the invention

In the illustrated embodiment, the first frames 110 are provided in a pair and spaced apart from each other in the left-right direction.

[0088] Since the plurality of first frames 110 are separated, an opening is formed. The opening is communicated with the accommodation space 140 described later. The server module 11 or the control module 12 can be inserted into the server rack system 10 or drawn out from the server rack system 10 through the opening.

[0089] In addition, the first frame 110 is a portion to which a support portion 220 of a cable strand structure 200 described later is coupled. The details of this will be described later together with the description of the cable strand structure 200.

The heat generated by the server module 11 or the control module 12 can be discharged to the outside through the opening. In addition, the server module 11 or the control module 12 can be combined with a wire member (not shown) for powering an external power source or terminal through the opening.

[0096] The cover portion 130 forms an appearance of another part of the frame portion 100. In the illustrated embodiment, the cover portion 130 forms an appearance of upper and lower sides.

[0097] The cover portion 130 is located at each end portion in the height direction of the frame portion 100 .

[0098] The cover 130 is configured to cover the space formed inside the frame 100. Specifically, the cover 130 is configured to cover the uppermost storage space 140 and the lowermost storage space 140 among the storage spaces 140 formed inside the frame 100.

[0099] The cover 130 may be provided in plural. The plural cover 130 may be arranged spaced apart in the height direction of the frame 100. In the illustrated embodiment, the cover 130 includes a first cover 131 and a second cover 132 and is provided as a pair. In the embodiment, the first cover 131 and the second cover 132 are spaced apart in the up-down direction.

[0100] The cover 130 is coupled to the ends of the first frame 110 and the second frame 120 in the extending direction. In the illustrated embodiment, the first cover 131 is coupled to the upper ends of the first frame 110 and the second frame 120, respectively, and the second cover 132 is coupled to the lower ends of the first frame 110 and the second frame 120, respectively.

[0101] A space formed by separating the plurality of cover parts 130 , that is, the first cover 131 and the second cover 132 is defined as an accommodation space 140 .

[0102] The accommodation space 140 is used as a space for accommodating the server module 11 and the control module 12. The server module 11 and the control module 12 may be inserted into the accommodation space 140 in a manner of being drawn out in the length direction of the frame portion 100.

[0103] The receiving space 140 may be defined to be surrounded by the first frame 110 , the second frame 120 , and the cover 130 .

[0104] In the illustrated embodiment, the front side of the accommodation space 140 is partially surrounded by the first frame 110. The rear side of the accommodation space 140 is partially surrounded by the second frame 120. The upper and lower sides of the accommodation space 140 are surrounded by the first cover 131 and the second cover 132, respectively.

[0105] The accommodation space 140 is in communication with the outside. The server module 11 and the control module 12 can be accommodated in the accommodation space 140 or led out from the accommodation space 140 through the portion of the accommodation space 140 that is in communication with the outside. In the illustrated embodiment, the server module 11 and the control module 12 can be accommodated in the accommodation space 140 or led out from the accommodation space 140 through the front side of the accommodation space 140 (see Figure 2 and Figure 3 ).

[0106] The accommodation space 140 may be formed in a shape corresponding to the frame portion 100. In the illustrated embodiment, the accommodation space 140 is formed to have a greater extension length in the front-rear direction than in the left-right direction and to have a height in the up-down direction.

[0107] The receiving space 140 may be divided into a plurality of spaces. Specifically, the receiving space 140 may be divided into a plurality of spaces in the height direction thereof. That is, the frame portion 100 is formed into a rack structure provided with a plurality of receiving spaces 140 .

[0108] The plurality of server modules 11 or control modules 12 are respectively accommodated in the plurality of spaces in an extractable manner. To this end, the accommodation space 140 is preferably formed in a shape corresponding to the server module 11 or the control module 12. In the illustrated embodiment, the accommodation space 140 is divided into a plurality of spaces in the up and down directions.

[0109] Generally, the length in the width direction of the server module 11 can be formed constantly according to standard specifications, but its height and depth can be formed variously. As described above, the accommodation space 140 can be formed to correspond to the server module 11 or the control module 12, so the height and depth of the accommodation space 140 can also be formed variously.

[0110] At this time, it can be understood that, among the divided plural accommodation spaces 140 , the upper side of the uppermost accommodation space 140 is surrounded by the first cover 131 , and the lower side of the lowermost accommodation space 140 is surrounded by the second cover 132 .

[0111] The frame portion 100 may be combined with an optical fiber cable stranding structure 200 that can individually measure the temperature of the server module 11 inserted into each accommodation space 140 .

[0112] Below, refer to Figures 4 to 8 , the cable strand structure 200 is described.

[0113] The cable strand structure 200 is configured to collect temperature data of the server modules 11 by being installed in the server rack system 10. Specifically, the cable strand structure 200 assists in installing the optical fiber cables C in conjunction with the frame portion 100 of the standardized rack structure, making it easy to measure the temperature of the plurality of server modules 11.

[0114] In one embodiment, the cable strand structure 200 can measure the temperature of the server module 11 and its surrounding environment using the cable C formed in the form of an optical fiber. The process of measuring temperature using an optical fiber is a well-known technology, so a detailed description is omitted.

[0115] The cable strand structure 200 is configured to surround a portion of the server module 11 as a temperature measurement target. In the illustrated embodiment, the cable strand structure 200 is configured to surround the left side, right side, and rear side of the server module 11 as a temperature measurement target.

[0116] The cable strand structure 200 is combined with the frame portion 100. In one embodiment, the cable strand structure 200 can be fixedly combined with the frame portion 100 or formed integrally.

[0117] The cable strand structure 200 can be electrically connected to an external terminal (not shown) to transmit the collected temperature data to the external terminal, etc. Thus, the administrator can easily collect the temperature information of the server rack system 10 .

[0118] The cable twisted wire structure 200 may be provided in plurality. In this case, the plurality of cable twisted wire structures 200 may be respectively coupled to different server modules 11 .

[0119] Therefore, the cable strand structure 200 can perform individual and independent heat tracking for each server module 11. As a result, it is easier to measure the temperature of a plurality of server modules 11. Further, the administrator can actively respond based on the temperature measurement results of each server module 11 and can provide appropriate status to each server module 11.

[0120] Furthermore, as the temperature data of each server is collected, a larger amount of temperature data can be collected, thereby further improving the reliability of the temperature measurement result of the cable stranded wire structure 200.

[0121] In one embodiment, a plurality of cable strand structures 200 may be connected to each other via one optical fiber cable C. Therefore, errors and mistakes that may be generated by using a plurality of contact temperature sensors may be further reduced by using a single temperature sensor optical fiber.

[0122] The plurality of cable strand structures 200 may be arranged spaced apart from each other in the height direction of the frame portion 100. In the illustrated embodiment, the plurality of cable strand structures 200 may be arranged spaced apart from each other in the up-down direction.

[0123] In the illustrated embodiment, the cable strand structure 200 includes a plate portion 210 and a support portion 220 .

[0124] Below, refer to Figures 4 to 7 , the plate portion 210 is described.

[0125] The board portion 210 is a portion that directly measures the temperature of the server module 11 .

[0126] The board portion 210 is disposed adjacent to the server module 11. In one embodiment, the board portion 210 may be disposed adjacent to the rear side of the server module 11.

[0127] The plate portion 210 is disposed in the storage space 140 of the frame portion 100. Therefore, the plate portion 210 is preferably formed to have a smaller length than the storage space 140 in the vertical, horizontal, and front-rear directions.

[0128] In addition, the plate portion 210 is located between two supporting portions 220 to be described later. Specifically, the plate portion 210 is connected to the two supporting portions 220 so that its position can be changed along the two supporting portions 220.

[0129] Therefore, the position of the plate portion 210 can be freely changed corresponding to the length of each server module 11. Thus, the cable strand structure 200 can be provided to correspond to servers of various lengths.

[0130] The plate portion 210 is formed to extend in the width direction of the frame portion 100. In the illustrated embodiment, the plate portion 210 is formed to extend in the left-right direction.

[0131] In the illustrated embodiment, the plate portion 210 is provided with an inner crimping member 211 , an outer crimping member 212 , a cable passing hole 213 , and an insertion portion 214 .

[0132] The inner crimping member 211 provides a crimping space for the optical fiber cable C for measuring the temperature.

[0133] In order to measure the temperature more accurately, the optical fiber cable C formed of optical fibers needs a measurement interval of a predetermined length or more. This is because the temperature is estimated within a predetermined error range at the center of the received temperature data, and the temperature estimation algorithm is set to estimate the temperature at predetermined intervals along the optical fiber cable C.

[0134] Therefore, in order to measure the temperature of a plurality of points at a short distance, it is necessary to increase the overall length of the optical fiber cable C by curling. The inner curling member 211 is a portion for curling such an optical fiber cable C.

[0135] The inner curling member 211 may be provided in plural. This is to make it easier to adjust the extension length of the optical fiber cable C according to the server module 11 as the temperature measurement object, the temperature detection sensitivity, etc. In the illustrated embodiment, three inner curling members 211 are provided. However, the inner curling member 211 is not limited to the illustrated embodiment, and may be provided in four or more.

In addition, the optical fiber cable C can be curled in all three inner curling members 211 (refer to Figure 7 (b)).

[0138] At this time, the number of the inner curling members 211 around which the optical fiber cable C is curled may be appropriately selected according to the server module 11 to be measured in temperature, the temperature detection sensitivity, and the like.

[0139] The inner curling member 211 is formed on one surface of the plate portion 210 .

[0140] The inner curled member 211 is formed to extend in a direction away from the one surface of the plate portion 210. At this time, the inner curled member 211 extends in a manner such that the outer diameter thereof extends in a direction away from the plate portion 210.

[0141] In one embodiment, the inner curling member 211 may be formed to extend toward the server module 11. In another embodiment, one end of the inner curling member 211 may be disposed adjacent to the server module 11.
