Please refer to FIGS. 1 to 6. FIG. 1 is a perspective view of a server according to one embodiment of the disclosure, FIG. 2 is a top view of the server in FIG. 1, FIG. 3 is an exploded view of the server in FIG. 1, FIGS. 4 to 5 are exploded views of the air baffle of the server in FIG. 1 taken from different viewpoints, and FIG. 6 is a schematic view showing the air baffle of the server in FIG. 1 being shifted to different air guiding positions. As shown in FIG. 1, a server 1 is provided, and the server 1 is adaptive to a server cabinet (not shown).
In detail, as shown in FIGS. 2 to 3, in this embodiment, the server 1 includes a casing 10, a fan module 20, a plurality of processor holders 30, at least one air baffle 40, an electronic component 95 and an electronic component 97.
The casing 10 includes two side boards 110 and a bottom board 111. The two side boards 110 are respectively disposed on two sides of the bottom board 111 are opposite to each other. The two side boards 110 and the bottom board 111 together form an accommodating space S1 for accommodating the fan module 20, the processor holders 30, the air baffle 40, the electronic component 95, the electronic component 97, and other required components.
The fan module 20 is disposed on the bottom board 111 in order to remove heat generated by the electronic component 95 and the electronic component 97. In detail, the fan module 20 has an air outlet side 20 a and an air inlet side 20 b respectively located on two sides of the fan module 20 opposite to each other. The air outlet side 20 a is located at a side of the fan module 20 facing the processor holders 30. In addition, in this embodiment, the fan module 20 includes a plurality of fans (not numbered), but the present disclosure is not limited to the number of the fans. In addition, from the point of view of FIG. 2, in this or some embodiments, the leftmost space of the fan module 20 has no fan because of actual factors, but the present disclosure is not limited thereto.
In this embodiment, the number of the processor holders 30 is two. The two processor holders 30 are disposed on the bottom board 111 and arranged close to the air outlet side 20 a of the fan module 20. However, the present disclosure is not limited to the number, the location or the configuration of the processor holder 30. In some embodiments, the number of the processor holders 30 can be three or over three, and its locations and configurations can be changed according to the actual requirements.
In addition, each processor holder 30 has a plurality of mounting holes (not numbered) configured for the mounting of the processor module (not shown). The mounting hole of the processor holder 30 is, for example, a threaded hole or a fastening hole, but the present disclosure is not limited thereto. The said processor module includes, for example, a central processing unit (CPU) and a heat sink. In addition, in most casings, the number of the processor holders is greater than the number of the processor modules required for minimum operation, so that the user is able to install more processor modules for future expansion. For example, in this embodiment, the server 1 has two processor holders 30, but one processor module is enough to meet the minimum operational requirement. Thus, in a standard server, there is only one processor holder 30 equipped with the processor module, and the other processor holder 30 are not equipped with any processor module. However, it is understood that all the processor holders 30 may be equipped with the processor modules according to actual requirements, and the present disclosure is not limited thereto.
The electronic component 95 is, for example, a hard disk module. The electronic component 97 is, for example, a power module. In this and some embodiments, the electronic component 95 and the electronic component 97 are disposed at the rear end of the casing 10 and located close to the processor holders 30. That is, the electronic component 95 and the electronic component 97 are located at a side of the processor holders 30 opposite to the fan module 20. Also, the electronic component 95 and the electronic component 97 are able to be cooled down by the airflow generated by the fan module 20.
In addition, there are other electronic components being mounted with the electronic component 95 and the electronic component 97 according to the configuration of the printed circuit board. For example, as shown FIG. 2, there is an area for expansion S2 located at the left and the right side of the electronic component 95 and the peripheral of the two processor holders 30. The so called area for expansion S2 is the area for placing expansion slots (not numbered). Each of the said expansion slots is, for example, a RAM slot or a PCI slot. Before the insertion of the RAM or PCI card, the area for expansion S2 is an open space. The components in the area for expansion S2 is not the cooling target of the fan module 20. That is, the area for expansion S2 is not the predetermined area required to be cooled down. However, the present disclosure is not limited to the location and the number of the area for expansion S2.
Then, the details of the air baffle 40 are described in the following paragraphs. The air baffle 40 is disposed on the processor holder 30 which is not mounted with any processor module, for controlling the airflow generated by the fan module 20. In detail, the air baffle 40 includes a base 410 and two airflow guiding members 420 a and 420 b which are connected to the base 410. The airflow guiding member 420 a and the airflow guiding member 420 a are respectively located at two sides of the base 410 which are opposite to each other. Although the airflow guiding member 420 a and the airflow guiding member 420 b are different in appearance, but they are similar in configuration and structural relationship with the base 410. Thus, for the purpose of description, only the airflow guiding member 420 a is illustrated in the following paragraphs.
The base 410 includes a protrusion part 411 and a mounting part 412 connected to each other. The protrusion part 411 is a box-shaped object, and the mounting part 412 is a plate-shaped object. The protrusion part 411 protrudes from a surface of the mounting part 412. The mounting part 412 is detachably mounted on one of the processor holders 30 not equipped with the processor module. In detail, the mounting part 412 has two through holes 412 a and four mounting holes 412 b. Each through hole 412 a is used for the installation of the airflow guiding member 420 a. The mounting holes 412 b are respectively located at four corners of the mounting part 412, and respectively correspond to the mounting holes (not numbered) on the processor holder 30. When the base 410 is mounted on one of the processor holders 30, screws (not shown) are able to be respectively inserted into the mounting holes 412 b of the mounting part 412 to be respectively fastened to the mounting holes on the processor holder 30, but the present disclosure is not limited to the way of fastening the mounting part 412 to the processor holder 30. In some embodiments, each of the mounting holes 412 b of the mounting part 412 can be replaced with a thread hole, a protrusion or a latch.
The airflow guiding member 420 a includes a pivoting part 421, a plate-shaped part 422 and a tab part 423 connected to one another. The pivoting part 421 is connected between the plate-shaped part 422 and the tab part 423. The pivoting part 421 is disposed on the through hole 412 a of the mounting part 412 and abutted against a side edge of the protrusion part 411. A fastener 81 penetrates through the through hole 412 a of the mounting part 412 to be fastened to the pivoting part 421, so that the pivoting part 421 is pivotable with respect to the mounting part 412. Thus, the airflow guiding member 420 a is able to be pivoted to the base 410 via its pivoting part 421. The plate-shaped part 422 is disposed on the pivoting part 421, and extends away from the pivoting part 421. The plate-shaped part 422 is pivoted with the pivoting part 421. The tab part 423 protrudes from the pivoting part 421, and is located at an edge of the pivoting part 421 close to the mounting part 412 of the base 410. The aforementioned fastener 81 is, for example, a screw, but the present disclosure is not limited thereto.
In more detail, as shown in FIG. 5, the tab part 423 has a through hole 423 a, the mounting part 412 has a plurality of fastening holes 412 c. When the airflow guiding member 420 a is pivoted with respect to the base 410, the through hole 423 a of the tab part 423 is selectively aligned with one of the fastening holes 412 c of the base 410. Then, a fastener 82 penetrates through the through hole 423 a to be fastened into the aligned fastening hole 412 c, so that the airflow guiding member 420 a is fixed in one of air guiding positions with respect to the base 410. The aforementioned fastener 82 is, for example, a screw, but the present disclosure is not limited thereto. In addition, in this embodiment, the mounting part 412 has three fastening holes 412 c, so that the airflow guiding member 420 a is able to be pivoted with respect to the base 410 to shift among three different air guiding positions. However, the present disclosure is not limited to the number of the fastening holes 412 c of the base 410 and the number of the air guiding positions. In some embodiments, the number of the fastening holes 412 c can be two or over three, and the number of the air guiding positions is changed according to the number of fastening holes 412 c.
In more detail, as shown in FIGS. 5 to 6, in this embodiment, the server 1 further includes two elastic members 60 and two gaskets 70. The mounting part 412 of the base 410 further has a plurality of positioning holes 412 d.
The elastic member 60 is, for example, a compression spring, but the present disclosure is not limited thereto. In some embodiments, the elastic member 60 can be replaced with an object, such as rubber which is deformable under load but able to recover to their original condition when the load is removed.
The pivoting part 421 has a cavity 421 s and two sliding grooves 4211. The cavity 421 s is configured for accommodating one of the elastic members 60 and one of the gaskets 70. The two sliding grooves 4211 are located at two sides of the cavity 421 s opposite to each other.
The positioning holes 412 d surround the through hole 412 a. In this embodiment, the number of the positioning holes 412 d is ten. The ten positioning holes 412 d are divided into two groups, and the two groups are respectively located at two sides of the through hole 412 a, but the present disclosure is not limited to the number of the positioning holes 412 d. In addition, in this embodiment, each positioning hole 412 d is a through hole, but the present disclosure is not limited thereto. In some embodiments, each positioning hole 412 d can be an indentation but not penetrating through the mounting part 412.
The gasket 70 is a disc-shaped object, and is made of, for example, rubber, but the present disclosure is not limited thereto. The gasket 70 is directly located on the positioning holes 412 d of the base 410. Each gasket 70 includes a main part 71, two ears 72 and a plurality of raised dots 73. The ears 72 are respectively located at two side edges of the main part 71 which are opposite to each other, and the ears 72 respectively correspond to the sliding grooves 4211 of the pivoting part 421. The raised dots 73 are located at a side of the main part 71 facing the mounting part 412, and the raised dots 73 surround the center of the main part 71. The raised dots 73 are selectively fixed into some of the positioning holes 412 d of the mounting part 412. In this embodiment, the number of the raised dots 73 is six, the six raised dots 73 are divided into two groups respectively located at two sides of the main part 71, but the present disclosure is not limited to the number of the raised dots 73.
In detail, the elastic member 60 and the gasket 70 are located in the cavity 421 s of the pivoting part 421. The gasket 70 is located at an end of the elastic member 60 opposite to the pivoting part 421; that is, the elastic member 60 is located between and pressed by the pivoting part 421 and the gasket 70. In more detail, the two ears 72 of the gasket 70 are respectively slidable in two sliding grooves 4211 of the pivoting part 421. The gasket 70 is constantly pushed away from the pivoting part 421 by the elastic member 60. Thus, when the airflow guiding member 420 a is pivoted with respect to the base 410, the gasket 70 is pivoted with the pivoting part 421, so that the raised dots 73 are selectively fixed into some of the positioning holes 412 d of the mounting part 412, for fixing the airflow guiding member 420 a in one of the air guiding positions with an efficient manner and providing a fool-proofing effect.
However, the elastic member 60, the gasket 70 and the positioning holes 412 d of the mounting part 412 are optional; the present disclosure is not limited thereto. In some embodiments, the elastic member 60 can be omitted, and the gasket 70 and the positioning holes 412 d are remained; in such a casing, the gasket may be fixed in place, but the gasket is still able to be rotated with respect to the mounting part 412. In yet another embodiment, the elastic member 60, the gasket 70 and the positioning holes 412 d may be all omitted. In addition, the tab part 423 and the fastening holes 412 c of the mounting part 412 are optional; the present disclosure is not limited thereto. In some embodiments, the tab part 423 and the fastening holes 412 c of the mounting part 412 may be omitted; in such a casing, the pivoting part 421 and the mounting part 412 are close-fit, so that the pivoting part 421 is able to be maintained at one of the air guiding positions while it is pivoted with respect to the mounting part 412.
The airflow guiding member 420 b is not illustrated hereafter since its configuration and the structural relationship with the base 410 are similar to that of the airflow guiding member 420 a. However, the airflow guiding member 420 a and the airflow guiding member 420 b can be different in shape and size according to the arrangement of the peripheral server components. That is, the present disclosure is not limited to the shape or the size of the plate-shaped part.
In addition, in the aforementioned embodiments, the air baffle 40 has two airflow guiding members, the airflow guiding member 420 a and the airflow guiding member 420 b, but the present disclosure is not limited to the number of the airflow guiding members. In some embodiments, the airflow guiding member 420 b or the airflow guiding member 420 a can be omitted. In such a casing, only one set of related components for the mounting of the airflow guiding member is remained. In yet another embodiment, the number of airflow guiding members can be three or over three, and these airflow guiding members are respectively located at different corners of the base.
In addition, in this or some embodiments, it is optional to mount a system air baffle (not shown) on the server 1, the system air baffle covers the electronic components such as the air baffle 40, the processor module and the processor holders 30 in order to guide the airflow generated by the air outlet side 20 a and prevent the airflow from escaping to outside from the air outlet side 20 a. However, the present disclosure is not limited to the system air baffle.
Then, the comparison between having the air baffle 40 and not having the air baffle 40 is illustrated in the following paragraphs. Please refer to FIG. 7, which is a schematic view showing the operation of the server in FIG. 1.
As shown in FIG. 7, the processor holder 30 is not disposed with the air baffle 40, and the processor holder is disposed with the air baffle 40. Firstly, please see the airflow F1 (shown in dashed line, and at the left side of the server 1), the airflow F1 is the airflow, which is generated by the fan module 20, flowing through the processor holder 30, which is not mounted with the processor module and the air baffle 40. The top of the processor holder 30, which is not mounted with the processor module and the air baffle 40, forms an open space thereabove, so the airflow F1 becomes more turbulent when flowing through the said open space. As a result, most of the airflow F1 in the said open space easily flows to the area for expansion S2 (i.e. the area having no requirement of being cooled down), for example, the area on the left side of the electronic component 95, so the airflow to the electronic component 95 is decreased, causing the electronic component 95 to overheat. The overheated electronic component 95 may affect the speed of its operation and shorten its lifespan, and further affect the operation of the server 1.
Then, please see the airflow F2 (shown in solid line, and at the left side of the server 1), the airflow F2 is the airflow, which is generated by the fan module 20, flowing through the processor holder, which is not mounted with the processor module but mounted with the air baffle 40. Because the airflow guiding members 420 a and 420 b are respectively pivotable with respect to the base 410 (i.e. each of the airflow guiding members 420 a and 420 b is able to be selectively shifted to a specific air guiding position), as seen from the point view of FIG. 7, the airflow F2 from the air outlet side 20 a of the fan module 20 is guided by the inclined airflow guiding members 420 a and 420 b of the air baffle 40 in order to flow to the electronic component 95 at the rear side of the server 1. That is, the airflow guiding members 420 a and the 420 b are favorable for efficiently control the airflow from the fan module so as to prevent the problem of the electronic component 95 lacking the airflow. Accordingly, the electronic component 95 is prevented from overheating, so that the operation of the server 1 is maintained in a standard condition.
In addition, please refer to FIG. 8, which is another schematic view showing the operation of the server according to one embodiment of the disclosure. As shown in FIG. 8, in this embodiment, the air baffle 40 is disposed on the processor holder 30 located at the right side of the server 1. Similar to the aforementioned embodiments, the airflow guiding members 420 a and 420 b are pivotable with respect to the base 410 (i.e. each of the airflow guiding members 420 a and 420 b is selectively shifted to different air guiding positions), so that the airflow generated by the fan module 20 is able to be guided by the air baffle 40 in order to flow to the electronic component at the rear side of the server 1, thereby providing sufficient air to the electronic components inside the server 1.
According to the server as discussed above, the air baffle is disposed on one of the processor holder which is not mounted with any processor module, and the airflow guiding member of the air baffle is able to be selectively shifted to different air guiding positions with respect to the server in accordance with the location of the air baffle, so the air baffle is able to guide the airflow generated by the fan module to the target electronic components, thereby preventing the said airflow from flowing to undesired area and maintaining the amount of cooling air for the said target electronic components. Therefore, the performance of the server is improved, and the amount of energy required to operate the fan module can be reduced.
In addition, the airflow guiding member can be pivoted with respect to the base in order to efficiently control the airflow of the fan module.
