Description

Server system and server case thereof

Technical Field

The present invention relates to a server case, and more particularly, to a server case with improved heat dissipation.

Background

With the popularity of digital living space and the demand for better network services, the host server does not need to be equipped with more hard disk devices to support storage resources in larger space, thereby expanding or enhancing the functions of the computer. Therefore, a high storage capacity server is indirectly facilitated.

The high storage capacity server is designed based on the factors of the storage capacity (the number of hard disks), the cabinet depth, the opening direction, the power supply estimation and the heat dissipation efficiency.

However, after the storage hard disk is fully loaded in the server, there is no extra space in the server, so the air flow circulation inside the server is not high, and the heat dissipation is not good, which needs to be improved.

Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. However, it will be apparent to one skilled in the art that these implementation details are not required in some embodiments of the invention and are not to be construed as limiting the invention. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. In addition, the dimensions of the various elements in the drawings are not necessarily to scale, for the convenience of the reader.

FIG. 1 is a perspective view of a server system 10 according to an embodiment of the invention. Fig. 2 is a perspective view of the servo 200 of fig. 1. Fig. 3 is a cross-sectional view taken along line AA of fig. 2. As shown in fig. 1 to 3, the server system 10 includes a rack 100, two support rails 130 and a server 200. The support rail 130 is oppositely disposed on the frame 100. The servo 200 is removably positioned within the interior space 120 of the rack 100 via the support rail 130. The server 200 includes a server housing 210, two guide rails 220, a separating structure 300 and a circuit board module 400. The two guide rails 220 are disposed on two opposite sides of the server housing 210, and are slidably connected to the support rails 130, respectively, for the server housing 210 to enter and exit the inner space 120 of the rack 100 along a moving direction (e.g., X axis). For example, the rack 100 includes four outer posts 110. The outer columns 110 are vertically spaced apart from each other to collectively enclose the interior space 120. Each support rail 130 is located in the interior space 120 and fixedly secured therein to the outer column 110. In this manner, the servo 200 can slide along the support rail 130 into the interior space 120 of the rack 100.

Fig. 4 is a front view of the servo housing 210 of fig. 2 with the storage device 450 fully loaded. As shown in fig. 2 and 4, the servo housing 210 is a substantially rectangular housing, and therefore has a first long axis direction L1, the first long axis direction L1 passes through the front side plate 213 and the rear side plate 214 of the servo housing 210, and the moving directions (e.g., X axis) are parallel to each other. The server casing 210 includes a cover 211, a bottom plate 212, a front plate 213, a rear plate 214, and an outer plate 215. The front plate 213, the rear plate 214 and the outer plate 215 are respectively located at the edge of the bottom plate 212 and extend toward an extending direction (e.g., Z axis). Therefore, the cover 211, the front plate 213, the rear plate 214 and the outer plate 215 together define a receiving space 216. The circuit board module 400 is located in the accommodating space 216 and disposed on the bottom plate 212 of the server case 210.

As shown in fig. 3 and 4, the separating structure 300 is located in the accommodating space 216 and separates a plurality of separating channels 340. The partition lanes 340 are arranged in a matrix manner, and the partition lanes 340 extend toward the bottom plate 212 of the server box 210 and face the bottom plate 212 of the server box 210, respectively. The separation channels 340 are arranged in series along the direction of movement (e.g., the X-axis). Each partition lane 340 has a lane length along the extending direction (e.g., Z-axis), and the lane lengths vary progressively in the moving direction (e.g., X-axis) in order from the front plate 213 to the rear plate 214 (fig. 3). Each of the dividing channels 340 is capable of receiving a plurality of storage devices 450 such that each storage device 450 is insertable into one of the dividing channels 340 in a plugging direction (e.g., Z-axis), and the storage devices 450 are received upright in the dividing channels 340. The inserting/extracting direction (e.g., Z axis) and the moving direction (e.g., X axis) are orthogonal to each other.

Thus, when the bays 340 are arranged in a matrix according to 3X8 and each bay 340 can accommodate 6 storage devices 450, the server rack 210 can have 144 storage devices 450 therein when the server rack 210 is fully loaded with storage devices 450.

Fig. 5 is a partially enlarged view of the region M1 of fig. 4. In the present embodiment, as shown in fig. 4 and 5, the partition structure 300 includes a straight partition plate 310, a plurality of first horizontal partition plates 320, and a plurality of second horizontal partition plates 330. The straight partition 310 is disposed in the accommodating space 216 along the first long axis direction L1, and is fixedly connected to the bottom plate 212 and the front plate 213 of the server housing 210. The straight partition 310 includes a first board 311 and a second board 312. The first board 311 and the second board 312 are stacked together by a riveting process.

The first transverse partitions 320 are arranged in parallel and connected to one side of the first plate 311 opposite to the second plate 312 at intervals, and each first transverse partition 320 has a second long axis direction L2. The second transverse partitions 330 are arranged in parallel and connected to one side of the second plate 312 opposite to the first plate 311 at intervals, and each third transverse partition has a third long axis direction L3. The third long axis direction L3 is coaxially aligned with the second long axis direction L2 and orthogonal to the first long axis direction L1. Therefore, each partition passage 340 is formed between two adjacent first diaphragms 320 or between two adjacent second diaphragms 330.

As shown in fig. 3, each first horizontal partition 320 is spaced from the bottom plate 212 of the server casing 210, that is, each first horizontal partition 320 has a height relative to the bottom plate 212, and the height variation of the first horizontal partitions 320 gradually decreases in the first long-axis direction L1 according to the sequence from the front side plate 213 to the rear side plate 214. Similarly, each second bulkhead 330 is spaced from the bottom plate 212 of the server chassis 210 (FIG. 3), i.e., each second bulkhead 330 has a height relative to the bottom plate 212. The height variation of these second diaphragms 330 gradually decreases in the first long-axis direction L1 in order from the front side plate 213 to the rear side plate 214.

More specifically, as shown in fig. 4, the accommodating space 216 of the servo housing 210 can be divided into a first area 301, a second area 302 and a third area 303 along the moving direction (e.g., X axis). The second region 302 is located between the first region 301 and the third region 303. The first region 301 has a plurality (e.g., 3) of partition lanes 340 in sequence along the moving direction (e.g., X-axis), the second region 302 has one partition lane 340 in sequence along the moving direction (e.g., X-axis), and the third region 303 has a plurality (e.g., 4) of partition lanes 340 in sequence along the moving direction (e.g., X-axis).

The storage devices 450 are, for example, hard disk modules, and in the present embodiment, the storage devices 450 may be divided into a plurality of first hard disk modules 460, a plurality of second hard disk modules 470, and a plurality of third hard disk modules 480. The second hard disk modules 470 are located between the first hard disk modules 460 and the third hard disk modules 480.

As shown in fig. 3, the circuit board module 400 includes a plurality of first supporting pillars 411, a plurality of second supporting pillars 412, a plurality of third supporting pillars 413, a plurality of first circuit boards 420, at least one second circuit board 430, and a plurality of third circuit boards 440. The first supporting column 411, the second supporting column 412 and the third supporting column 413 are respectively fixed on the bottom plate 212. The first circuit board 420 is located in each of the dividing channels 340 of the first region 301, and is mounted on the bottom plate 212 through the first supporting pillars 411. The second circuit board 430 is located in each of the separation channels 340 of the second area 302, i.e. between the first circuit board 420 and the third circuit board 440, and is mounted on the bottom plate 212 through the second supporting posts 412. A third circuit board 440 is disposed in each of the partition lanes 340 of the third area 303, and is mounted on the bottom plate 212 through the third supporting posts 413. The distance between the second circuit board 430 and the bottom plate 212 is smaller than the distance between the first circuit board 420 and the bottom plate 212 and larger than the distance between the third circuit board 440 and the bottom plate 212.

The first hard disk modules 460 are respectively located in the partition channels 340 of the first area 301 in parallel along the second long axis direction L2, and each first hard disk module 460 enters the partition channel 340 along the plugging direction (such as the Z axis) and is inserted on the first circuit board 420 of the circuit board module 400. Each first hard disk module 460 has a first minimum linear distance 461 to the base 212. The second hard disk modules 470 are respectively located in the partition lanes 340 of the second area 302 in parallel along the second long axis direction L2, and each second hard disk module 470 enters the partition lane 340 along the plugging direction (e.g. Z axis) and is inserted into the circuit board module 400. Each second hard disk module 470 has a second minimum linear distance 471 from the bottom plate 212. The third hard disk modules 480 are respectively located in the partition lanes 340 of the second area 302 in parallel along the second long axis direction L2, and each third hard disk module 480 enters the partition lane 340 along the plugging direction (e.g. Z axis) and is inserted into the circuit board module 400. Each third hard disk module 480 has a third minimum linear distance 481 from the bottom plate 212. The first minimum straight-line distance 461 is greater than the second minimum straight-line distance 471, and the second minimum straight-line distance 471 is located between the first minimum straight-line distance 461 and the third minimum straight-line distance 481.

In addition, the server casing 210 further includes a plurality of independent slots 350 and a fan assembly 500. Each independent slot 350 is located on the surface of the first board 311 opposite to the second board 312, and is connected to two of the first diaphragms 320, so that an interface card device 600 can be inserted into the slot along the inserting and pulling direction (e.g., Z axis) and connected to the circuit board module 400. The long axis direction (e.g., X axis) of the independent slot 350 is parallel to the first long axis direction L1 of the server housing 210. The fan sets 500 are juxtaposed in the server case 210 along the second longitudinal direction L2 and located between the partition structure 300 and the rear side plate 214 (fig. 4) for providing air flow to the storage devices 450 in the partition structure 300.

Fig. 6 is a partially enlarged view of the region M2 of fig. 2. Fig. 7 is a partially enlarged view of the region M3 of fig. 4. As shown in fig. 6 and 7, opposite sides of each first diaphragm 320 have a plurality of first elongated protrusions 360 and a plurality of second elongated protrusions 370. The first elongated protrusions 360 are disposed at intervals along the second longitudinal direction L2, and protrude toward the adjacent first transverse partition 320. A first guiding groove 361 is formed between any two adjacent first narrow and long protrusions 360. The first guide grooves 361 are parallel to each other. The second elongated protrusions 370 are spaced apart along the second longitudinal direction L2, and each protrude toward the adjacent first horizontal partition plate 320. A second guiding groove 371 is formed between any two adjacent second elongated protrusions 370. These second guide grooves 371 are juxtaposed in parallel with each other. In each partition lane 340, the storage device (e.g., the first hard disk module 460) can enter the corresponding partition lane 340 along the inserting and pulling direction (e.g., the Z axis) by being guided by the first guide groove 361 and the second guide groove 371, so as to connect the circuit board module 400.

More specifically, in the first diaphragms 320 on both sides of each partition passage 340, the corresponding second guide grooves 371 and first guide grooves 361 are coaxially aligned with each other, and the width 371W of the second guide grooves 371 is different from the width 361W of the first guide grooves 361. Thus, the two sides of the storage device (e.g., the first hard disk module 460) are also set to have different widths, so that the two sides of the storage device (e.g., the first hard disk module 460) can only move along the first guide groove 361 and the second guide groove 371, thereby providing a foolproof mechanism that the storage device can only be placed in a specific direction.

In addition, each of the first elongated protrusions 360 has a first elongated through hole 362. The first elongated through hole 362 penetrates one of the diaphragms. Each second elongated protrusion 370 has a second elongated through hole 372. The second long through hole 372 passes through another first diaphragm 320. The second long through hole 372 and the first long through hole 362 are connected to one of the separation channels 340, respectively. Thus, the smoothness of the airflow in the servo housing 210 is enhanced.

Fig. 8 is an operational perspective view of the servo system 10 of fig. 1. As shown in fig. 2 and 8, the server 200 further includes a base 230 and a wire management rack 240. The base 230 is fixed on the rack 100 and carries the server case 210. The base 230 has a circuit signal group 231 therein. The first connector 232 of the circuit signal group 231 is electrically connected to the second connector 490 of the circuit board module 400 through the signal wire 241, and the circuit signal group 231 is not limited to any functional working circuit. The wire-arranging frame 240 is flexible and connects the server case 210 and the base 230 for covering and protecting the signal wires 241.
