Description

Server device and its chassis

The present disclosure relates to a server device, and more particularly to a chassis of the server device.

Generally speaking, servers contain a variety of sophisticated electronic components, such as hard disk drives (HDDs), central processing units (CPUs), and graphics processing units (GPUs). The performance of sophisticated electronic components is easily affected by noise and vibration, especially the performance of hard disks.

Currently, the interior of the server has a sound-absorbing or noise-reducing structure to reduce the noise generated by the internal fan, thereby reducing the vibration. However, there is a lack of effective solutions for reducing and blocking the noise generated outside the server.

In view of the above-mentioned problems, the main purpose of the present disclosure is to provide a server device and a chassis thereof, which can achieve the effects of both heat dissipation and reduction of external noise through a sound-absorbing structure and configuration of the chassis.

To achieve the above-mentioned purpose, the present disclosure provides a chassis for application in a server device. The server device includes a plurality of hard disk modules. The chassis includes a body, a partition, a cover, and at least one sound-absorbing structure. The body includes an opening and a storage space, and the hard disk modules are accommodated in the storage space. The partition is arranged at the opening. The partition includes a first side, a second side opposite to the first side, and at least one flow channel. The first side faces the storage space, and the flow channel passes through the first side and the second side. The cover is arranged at the opening of the body, and the cover has a plurality of ventilation holes. The sound-absorbing structure is arranged between the second side of the partition and the cover and corresponds to the flow channel. The sound-absorbing structure includes a sound-absorbing element and a reflecting element. The reflective element is arranged on one side of the sound absorbing element.

To achieve the above-mentioned purpose, the present disclosure further provides a server device, which includes a chassis and a plurality of hard disk modules. The chassis includes a body, a partition, a cover and at least one sound-absorbing structure. The body includes an opening and a storage space. The partition is arranged at the opening. The partition includes a first opposite side, a second side opposite to the first side, and at least one flow channel. The first side faces the storage space, and the flow channel passes through the first side and the second side. The cover is arranged at the opening of the body, and the cover has a plurality of ventilation holes. The sound-absorbing structure is arranged between the second side of the partition and the cover and corresponds to the flow channel. The sound-absorbing structure includes a sound-absorbing element and a reflective element. The reflective element is arranged on one side of the sound-absorbing element. The hard disk module is accommodated in the storage space.

According to an embodiment of the present disclosure, the sound absorbing element is a porous material.

According to an embodiment of the present disclosure, the reflective element is a plastic plate or a metal plate.

According to an embodiment of the present disclosure, the reflective element is disposed on the second side of the sound absorbing element facing the partition.

According to an embodiment of the present disclosure, the flow channel has an open surface, and there is a first distance between the muffler structure and the open surface.

According to an embodiment of the present disclosure, a ratio of the first distance to an inner diameter of the flow channel is between 0.5 and 2.

According to an embodiment of the present disclosure, a projection surface of the sound-absorbing structure projected onto the partition shields the open surface.

According to an embodiment of the present disclosure, a second distance is provided between a side wall of the flow channel and an extension line of a side wall of the muffler structure, and a ratio of the second distance to the first distance is between 1 and 2.

According to an embodiment of the present disclosure, an end of the flow channel close to the open surface has a flow guide portion.

As described above, according to the server device and its chassis disclosed herein, the chassis includes a body, a partition and at least one sound-absorbing structure. The partition and the sound-absorbing structure are both disposed at the opening of the body, and the sound-absorbing structure is disposed on the side of the partition facing outward (i.e., the second side) and corresponds to the flow channel. When the external noise of the server device enters the chassis, the sound energy can be first blocked and absorbed by the sound-absorbing structure, thereby preventing the external noise from affecting the performance of the hard disk module. In addition, the sound-absorbing structure includes a sound-absorbing element and a reflective element, and the reflective element is disposed on one side of the sound-absorbing element. The sound-absorbing element can absorb the sound energy, and the reflective element can reflect the sound energy back into the sound-absorbing element, thereby enhancing the sound-absorbing effect of the sound-absorbing structure.

FIG1 is a schematic diagram of a server device of an embodiment of the present disclosure, FIG2 is an exploded schematic diagram of the server device shown in FIG1, FIG3 is a three-dimensional cross-sectional view of the server device shown in FIG1 at line A-A, and FIG4 is a cross-sectional view of the server device shown in FIG1 at line A-A. Please refer to FIG1, FIG2, FIG3 and FIG4. The server device S of this embodiment includes a chassis 1 and a plurality of hard disk modules 9. The chassis 1 includes a body 10, a partition 20, at least one sound-absorbing structure 30 and a cover 40. The body 10 includes an opening 11 and a accommodating space 12, as shown in FIG2. In addition, the accommodating space 12 can be connected to the outside of the body 10 through the opening 11. The hard disk module 9 is accommodated in the accommodating space 12 of the body 10 and is close to the opening 11, as shown in FIG2 and FIG3. It should be noted that the hard disk module 9 shown in FIG. 2 is located in the accommodation space 12 of the main body 10 .

In the present embodiment, the partition 20 includes a first side surface 21, a second side surface 22 opposite to the first side surface 21, and at least one flow channel 23. The flow channel 23 penetrates the first side surface 21 and the second side surface 22, as shown in FIG3. It should be noted that the partition 20 in FIG3 and FIG4 is cut exactly at the flow channel 23. In the present embodiment, the partition 20 is disposed at the opening 11 of the body 10, and the first side surface 21 of the partition 20 faces the accommodating space 12, and the second side surface 22 faces the outside of the chassis 1. The flow channel 23 is a wind duct for the air outside the server device S to flow into the chassis 1. Furthermore, the partition plate 20 of the present embodiment has a plurality of flow channels 23, which can correspond to the hard disk modules 9 respectively, so that the external cold air can flow into the chassis 1 through the flow channels 23 and flow through the hard disk modules 9 to achieve a cooling effect.

In this embodiment, the muffler structure 30 and the cover plate 40 are disposed at the opening 11 of the body 10, and the muffler structure 30 is disposed between the partition plate 20 and the cover plate 40. In other words, at the opening 11 of the body 10, the cover plate 40, the muffler structure 30 and the partition plate 20 are disposed in sequence from the outside to the inside. FIG5 is a cross-sectional view of the server device shown in FIG1 at the B-B line, please refer to FIG2 and FIG5. Preferably, the number of the muffler structures 30 is the same as the number of the flow channels 23, so that each muffler structure 30 can correspond to each flow channel 23 respectively. Preferably, the muffler structure 30 can cover the opening of the flow channel 23, which is referred to as the open surface 231 here, as shown in FIG5. Specifically, the flow channel 23 has an open surface 231, which is the opening of the flow channel 23 toward the outside. The width of the muffler structure 30 is greater than the inner diameter of the flow channel 23 and its open surface 231, so the projection surface of the muffler structure 30 onto the partition 20 can cover the open surface 231.

As shown in FIG. 3 and FIG. 4 , the cover plate 40 has a plurality of ventilation holes 41. The sound-absorbing structure 30 is fixed by the cover plate 40, wherein the fixing method may include gluing, locking, hot melting or other methods, but is not limited thereto. In addition, the cover plate 40 is often referred to as a front window, so the sound-absorbing structure 30 of this embodiment is disposed on the side of the cover plate 40 facing the accommodation space 12 of the main body 10.

Since the sound-absorbing structure 30 is disposed between the cover plate 40 and the second side surface 22 of the partition plate 20, and is close to the opening 11 of the main body 10, when the external noise of the server device S enters the chassis 1, the sound energy can be first blocked and absorbed by the sound-absorbing structure 30. FIG6 is an enlarged schematic diagram of the sound-absorbing structure shown in FIG2, and please refer to FIG2, FIG4, FIG5 and FIG6. In this embodiment, the sound-absorbing structure 30 includes a sound-absorbing element 31 and a reflective element 32. Among them, the reflective element 32 is disposed on one side of the sound-absorbing element 31. The sound-absorbing element 31 is used to absorb sound energy, and the reflective element 32 can reflect the sound energy back into the sound-absorbing element 31, thereby achieving the sound-absorbing effect of the sound-absorbing structure 30. Specifically, the density of the sound absorbing element 31 is less than that of the reflective element 32, so that the reflective element 32 can achieve the effect of reflecting sound energy. In this embodiment, the sound absorbing element 31 can be a porous material, such as sound absorbing foam. The reflective element 32 can be a plastic plate or a metal plate.

Preferably, the reflective element 32 is disposed on the second side surface 22 of the sound absorbing element 31 facing the partition 20. In other words, the sound absorbing element 31 of the sound-absorbing structure 30 faces (i.e., is close to) the cover 40, while the reflective element 32 faces (i.e., is close to) the partition 20 and the hard disk module 9. Therefore, after the external noise of the server device S enters the chassis 1 through the vent 41 of the cover 40 along with the airflow (as shown by the direction arrow in FIG. 5 ), it is first absorbed by the sound absorbing element 31 of the sound-absorbing structure 30. Then, when the sound energy is transmitted to the reflective element 32, part of the sound energy can be reflected back to the sound absorbing element 31, thereby improving the sound-absorbing effect of the sound-absorbing structure 30 and greatly reducing the external noise of the server device S from entering the chassis 1.

FIG7 is a partially enlarged schematic diagram of the server device shown in FIG5 , please refer to FIG5 and FIG7 . Preferably, there is a gap between the silencer structure 30 and the partition 20 of the present embodiment. Specifically, there is a first distance D1 between the silencer structure 30 and the open surface 231 of the flow channel 23, as shown in FIG7 . Therefore, the airflow from the outside of the server device S can still flow into the flow channel 23 through the gap between the silencer structure 30 and the flow channel 23, and flow toward the hard disk module 9, as shown by the direction arrow in FIG5 . Preferably, the ratio of the first distance D1 to the inner diameter I of the flow channel 23 is between 0.5 and 2. For example, if the inner diameter I of the flow channel 23 is 2 centimeters (cm), the first distance D1 can be between 1 cm and 4 cm.

As mentioned above, the width of the muffler structure 30 of the present embodiment is greater than the inner diameter I of the flow channel 23 and its open surface 231, so that the projection surface of the muffler structure 30 projected onto the partition 20 can cover the open surface 231. In other words, there is a second distance D2 between the side wall of the flow channel 23 and the extension line of the side wall of the muffler structure 30. Preferably, the ratio of the second distance D2 to the first distance D1 is between 1 and 2. For example, if the first distance D1 is 1 cm, the second distance D2 can be between 1 cm and 2 cm. By limiting the first distance D1 and the second distance D2, the airflow outside the server device S can still flow into the flow channel 23 to achieve the function of cooling the hard disk module 9, and the external noise can be absorbed by the muffler structure 30 to avoid affecting the performance of the hard disk module 9.

FIG8 is an enlarged schematic cross-sectional view of a chassis of another embodiment of the present disclosure, please refer to FIG8 . The difference between the chassis 1a of the present embodiment and the aforementioned embodiment lies in the partition 20a, so other components use the same component symbols as the aforementioned embodiment. The flow channel 23a of the partition 20a of the present embodiment has a guide portion 232a at one end close to the open surface 231a. That is, the guide portion 232a is located at one end of the flow channel 23a close to the open surface 231a. In other words, the guide portion 232a is close to the second side surface 22a of the partition 20a. Specifically, the inner wall of the flow channel 23a of the present embodiment is mainly a vertical inner wall, and is located in the center of the flow channel 23a, which is biased toward the first side surface 21a. The area of the flow channel 23a close to the second side surface 22a and the open surface 231a forms a guiding structure different from the vertical inner wall to serve as a guide portion 232a.

In this embodiment, the guide portion 232a can be a gradually expanding arc angle or inclined surface, and Figure 8 takes a gradually expanding arc surface as an example. The structure of the guide portion 232a can enhance the smoothness of the airflow, so that the airflow can smoothly flow into the flow channel 23a to avoid turbulence near the open surface 231a.

In addition, the present disclosure also provides a chassis that can be applied to a server device. For the components of the chassis and their connection relationships, reference can be made to the chassis 1 and 1a of the aforementioned embodiments, which will not be described in detail here.

In summary, according to the server device and its chassis disclosed herein, the chassis includes a body, a partition and at least one sound-absorbing structure. The partition and the sound-absorbing structure are both disposed at the opening of the body, and the sound-absorbing structure is disposed on the side of the partition facing outward (i.e., the second side) and corresponds to the flow channel. When the external noise of the server device enters the chassis, the sound energy can be first blocked and absorbed by the sound-absorbing structure, thereby preventing the external noise from affecting the performance of the hard disk module. In addition, the sound-absorbing structure includes a sound-absorbing element and a reflective element, and the reflective element is disposed on one side of the sound-absorbing element. The sound-absorbing element can absorb the sound energy, and the reflective element can reflect the sound energy back into the sound-absorbing element, thereby enhancing the sound-absorbing effect of the sound-absorbing structure.

It should be noted that the above embodiments are given as examples for the purpose of explanation, and the scope of rights claimed by the present disclosure should be based on the scope of the patent application, rather than being limited to the above embodiments.
