Description

[Technical field]

[0001] The present disclosure relates to a server cooling device. [Background technology]

[0002] Conventionally, a server cooling device has been used to house and cool servers. Patent Document 1 discloses a technology in which multiple external storage units are housed in a storage space partitioned by partition walls, and the external storage units are cooled by cooling air from a cooling fan. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-146660 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology of Patent Document 1, the placement of the servers depends on the position of the partition walls, so the degree of freedom in placement is low and the servers cannot be accommodated efficiently. Furthermore, in the technology of Patent Document 1, the cooling performance varies depending on the positions of the partition walls and cooling fans.

[0005] The present disclosure has been made in consideration of the above, and has an object to provide a server cooling device that allows a high degree of freedom in arranging servers and has uniform cooling performance. [Means for solving the problem]

[0006] The server cooling device according to the present disclosure includes a case that houses a server and that can be filled with a quantity of cooling liquid according to the dimensions of the server so as to cover the outer surface of the server. Effect of the Invention

[0007] According to the present disclosure, it is possible to realize a server cooling device that allows a high degree of freedom in arranging servers and has uniform cooling performance. [Brief description of the drawings]

[0008] [Figure 1] FIG. 1 is a schematic configuration diagram of a server cooling system including a server cooling device according to a first embodiment. [Diagram 2] FIG. 2 is a schematic configuration diagram of a server cooling system including a server cooling device according to the second embodiment. [Diagram 3] FIG. 3 is a schematic configuration diagram of a server cooling system including a server cooling device according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A server cooling device according to an embodiment of the present disclosure will be described with reference to the drawings. Note that components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] (Embodiment 1) [Server Cooling System] Fig. 1 is a schematic configuration diagram of a server cooling system including a server cooling device according to embodiment 1. As shown in Fig. 1, the server cooling system 1 includes a plurality of server cooling devices 10 stored vertically in an immersion tank 14.

[0011] [Server cooling device] The server cooling device 10 includes a server 11, a cooling fluid 12, and a case 13.

[0012] Server 11 includes a calculation unit and an external storage unit. For example, the width (direction perpendicular to the plane of FIG. 1) and height (left-right direction in FIG. 1) of server 11 are regulated by standards, and the length (up-down direction in FIG. 1) is set arbitrarily. Specifically, server 11 has a width of 19 inches (482.6 mm), a height of 1.75 inches (44.45 mm), and a length that is set arbitrarily. Server 11 is stored vertically in immersion tank 14 (the side of server 11 is on the near side of the plane of FIG. 1, and the front and back of server 11 are at the top and bottom of FIG. 1).

[0013] Furthermore, server 11 is accommodated so as to be retractable towards the front side of the paper in Fig. 1. A passage having a width equal to or greater than the length of server 11 is provided between each of the immersion tanks 14 arranged in a vertical direction on the paper in Fig. 1. Server 11 that has been retracted towards the front side of the paper in Fig. 1 can be lifted upward and removed. Server 11 may be attached to a rail that allows it to be retracted towards the front side of the paper in Fig. 1, or it may be placed directly on a shelf board.

[0014] The coolant 12 is a refrigerant such as oil that cools the server 11 .

[0015] The case 13 accommodates the server 11 and can be filled with a quantity of cooling liquid 12 according to the size of the server 11 so as to cover the outer surface of the server 11 .

[0016] According to the server cooling device 10 described above, no partition walls are required, allowing for greater freedom in arranging the servers 11. Furthermore, since each server 11 can be individually cooled by the cooling liquid 12, the cooling performance is uniform.

[0017] Furthermore, according to the first embodiment, the servers 11 are accommodated with the same width and length. As a result, the width of the aisles between the servers 11 can be set to be approximately equal to the width of the servers 11, and more servers 11 can be accommodated.

[0018] Furthermore, when immersing a server, the server is lifted upward from an immersion tank storing a coolant and removed, requiring a space above the immersion tank for removal. In contrast, in the first embodiment, server 11 can be pulled out to the front side of the paper surface of FIG. 1, allowing server 11 to be stored efficiently.

[0019] (Embodiment 2) The server cooling system 101 includes a plurality of server cooling devices 110 stored vertically in an immersion tank 114. Note that a description of the same configuration as in the first embodiment will be omitted.

[0020] The server cooling device 110 includes a server 111 , a cooling fluid 112 , and a case 113 .

[0021] The server 111 is stored vertically (the front or rear of the server 111 is on the near side of the paper surface of FIG. 1, and the side of the server 111 is on the top and bottom of FIG. 1) in the liquid immersion tank 114. Furthermore, the servers 111 can be stacked vertically.

[0022] According to the server cooling device 110 described above, no partition walls are required, allowing for greater freedom in arranging the servers 111. Furthermore, since each server 111 can be individually cooled by the cooling liquid 112, the cooling performance is uniform.

[0023] Furthermore, according to the second embodiment, the servers 111 are accommodated so that both ends of the width direction, which has a constant length, are aligned vertically. As a result, more servers 111 can be accommodated vertically.

[0024] (Embodiment 3) The server cooling system 201 includes a plurality of server cooling devices 210 stored horizontally in an immersion tank 214. Note that a description of the same configuration as in the first embodiment will be omitted.

[0025] The server cooling device 210 includes a server 211 , a cooling fluid 212 , and a case 213 .

[0026] The server 211 is stored vertically in the immersion tank 214 (the front or rear of the server 211 is on the near side of the paper in FIG. 1, and the side of the server 211 is on the left or right side of FIG. 1). Furthermore, the servers 211 can be stacked vertically.

[0027] According to the server cooling device 210 described above, no partition walls are required, allowing for greater freedom in arranging the servers 211. Furthermore, since each server 211 can be individually cooled by the cooling liquid 212, the cooling performance is uniform.

[0028] Furthermore, according to the third embodiment, the servers 211 are accommodated so that both ends of the width direction, which has a constant length, are aligned in the left-right direction. As a result, more servers 211 can be accommodated in the left-right direction.

[0029] Furthermore, according to the third embodiment, maintenance such as replacement of parts inside the server 211 can be performed without removing the server 211 from the liquid immersion tank 214.

[0030] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
