Description

[0001] This application claims priority to Chinese Patent Application No. 202010044807.0, filed on January 16, 2020, entitled "A Hard Disk Frame", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of information technology, and more particularly to a chassis and storage device. Background Technology

[0003] As data volumes grow exponentially, users are placing higher demands on the storage capabilities of storage devices. Storage capacity is a key factor influencing the storage capacity of a storage device. Simply put, the capacity of a single hard drive and the number of hard drives determine the storage capacity of the storage device; with the increase in the number of hard drives and power consumption, the industry is also placing higher demands on the heat dissipation performance of storage devices. However, the structure of the chassis has a significant impact on the heat dissipation performance of storage devices. Therefore, how to rationally arrange the chassis structure is a key factor in improving the storage and heat dissipation performance of storage devices. Summary of the Invention

[0004] This application provides a chassis and storage device that can effectively ensure heat dissipation.

[0005] On one hand, this application provides a chassis for accommodating, supporting, or fixing electrical components. Specifically, the chassis may include a housing and a bracket located within the housing. Electrical components can be fixed to the bracket. When the bracket is located within the housing, the housing provides a certain degree of protection or airtightness for the bracket and the electrical components fixed to it. For ease of maintenance, the chassis provided in this application has a channel penetrating through a first end and a second end of the housing, and the bracket is slidably disposed within the channel. Furthermore, to facilitate the installation and heat dissipation of electrical components, the bracket includes a first receiving compartment, a fan compartment, and a second receiving compartment, arranged sequentially from the first end to the second end of the channel. When the bracket slides out from the first end of the housing (or channel), the first receiving compartment is exposed outside the housing, facilitating user maintenance of the electrical components within it. When the bracket slides out from the second end of the housing (or channel), the second receiving compartment is exposed outside the housing, facilitating user maintenance of the electrical components within it. The fan compartment is used to mount a cooling fan. Specifically, when the bracket is not slid out of the housing, the cooling fan generates a pressure difference through its rotation. Air outside the housing can enter the first compartment from the first end of the housing, flow through the fan compartment to the second compartment, and finally exit from the second end of the housing. In other words, the cooling airflow generated by the cooling fan can enter the first compartment from the first end of the housing, flow through the fan compartment to the second compartment, and exit from the second end of the housing. Thus, the cooling fan can generate cooling airflow that passes through both the first and second ends of the channel, and can flow through both compartments, thereby providing good heat dissipation for the electrical components within both compartments.

[0006] In addition, in some embodiments, an additional storage compartment may be provided in the chassis. For example, in one embodiment provided in this application, an auxiliary storage compartment is also provided. The auxiliary storage compartment may be located around the periphery of the bracket and the chassis bracket, and the auxiliary storage compartment extends through the first and second ends of the chassis; a baffle is provided inside the auxiliary storage compartment, and the baffle is located within the projection of the fan compartment into the auxiliary storage compartment, the baffle dividing the auxiliary storage compartment into a third storage compartment and a fourth storage compartment; the third storage compartment is located on one side of the first storage compartment, and the fourth storage compartment is located on one side of the second storage compartment. Furthermore, the first receiving compartment has a first connecting port, and the second receiving compartment has a second connecting port. When the bracket is not slid out of the housing, the first and third receiving compartments are connected through the first connecting port, and the second and fourth receiving compartments are connected through the second connecting port. Part of the cooling airflow generated by the cooling fan can enter the first receiving compartment from the first end of the housing, flow through the fan compartment to the second receiving compartment, and exit from the second end of the housing; another part can enter the third receiving compartment from the first end of the housing, enter the first receiving compartment through the first connecting port, flow through the fan compartment to the second receiving compartment, then exit through the second connecting port into the fourth receiving compartment, and exit from the second end of the housing. This structural arrangement ensures that the cooling airflow generated by the cooling fan effectively dissipates heat from the first, second, third, and fourth receiving compartments, thus improving the housing's heat dissipation performance. Specifically, the first receiving compartment has a first connecting port on its side wall, and the second receiving compartment has a second connecting port on its side wall; or, the first receiving compartment has a first connecting port at its bottom, and the second receiving compartment has a second connecting port at its bottom; or, one connecting port is on the side wall, and one connecting port is at the bottom.

[0007] When the first receiving compartment in the bracket is pulled out from the first end of the housing, in order to ensure continuous heat dissipation, an anti-backflow plate is also provided inside the housing in one embodiment of this application. In a specific implementation, the anti-backflow plate is rotatably installed in the channel. After the first receiving compartment slides out of the housing, the anti-backflow plate blocks the second end of the second receiving compartment. At this time, the cooling airflow generated by the cooling fan can flow from the first receiving compartment through the fan compartment to the second receiving compartment, then through the channel into the fourth receiving compartment, and finally out from the second end of the housing.

[0008] When the second receiving compartment in the bracket is pulled out from the second end of the housing, in order to ensure the continuity of heat dissipation, in another embodiment provided in this application, after the second receiving compartment slides out of the housing, the second receiving compartment can be connected to the fourth receiving compartment through the first connecting port. Part of the cooling airflow generated by the cooling fan can enter the first receiving compartment from the first end of the housing through the channel, flow through the fan compartment to the second receiving compartment, and then be discharged; the other part can enter the fourth receiving compartment from the second end of the housing, enter the first receiving compartment through the first connecting port, flow through the fan compartment to the second receiving compartment, and then be discharged.

[0009] In addition, the type of channel can be varied in actual implementation.

[0010] For example, the channel can be straight; that is, the support can slide along a straight path within the channel. Alternatively, the channel can be arc-shaped; that is, the support can slide along an arc-shaped path within the channel.

[0011] In some embodiments, the lengths of the first and second receiving compartments can vary. For example, the first and second receiving compartments can be the same length; or they can be symmetrically arranged about the fan compartment. In other embodiments, the length of the first receiving compartment can be greater than or less than the length of the second receiving compartment.

[0012] In addition, this application also provides a storage device, including any of the aforementioned chassis. A cooling fan is installed in the heat dissipation compartment of the chassis, and hard drives are installed in the first and second receiving compartments. Furthermore, the storage device also includes a circuit board assembly, which can be arranged in various ways in specific implementations. For example, the circuit board assembly may include a control board and / or a power module. The circuit board assembly can be electrically connected to the hard drives in the bracket via cables. Additionally, to increase cable reliability, the cables can be mounted on a tank chain, with one end of the tank chain fixedly connected to the bracket and the other end fixedly connected to the chassis. When the bracket slides relative to the chassis, the tank chain provides good protection for the cables, preventing tangling, wear, pull-out, and other adverse phenomena. Furthermore, the circuit board assembly can be installed in an auxiliary receiving compartment. Specifically, the control board assembly can be fixed to the inner side or bottom wall of the chassis.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0021] To facilitate understanding of the chassis provided in the embodiments of this application, its application scenarios will be introduced first.

[0022] The chassis provided in this application embodiment can be applied to various electronic devices to house, support, or fix electrical components within the electronic device. For example, the chassis can be used in storage devices. Specifically, the storage device may include a hard drive (which may be a mechanical hard drive or a solid-state drive, etc.), a circuit board assembly, and a cooling fan. The hard drive, circuit board assembly, and cooling fan can be fixed inside the chassis, which provides protection for the hard drive, circuit board assembly, and cooling fan to improve the security of the storage device. In a specific implementation, the hard drive is used to store data to realize the storage function of the storage device; the circuit board assembly is electrically connected to the hard drive to realize functions such as power supply, data allocation, and reading; the cooling fan can generate cooling airflow to dissipate heat from the hard drive and circuit board assembly to ensure the normal operation of the storage device. The circuit board assembly and the hard drive can be electrically connected via cables.

[0023] In some implementations, the chassis may include a housing and a pull-out bracket within the housing. The hard drive and circuit board assembly can be housed within the bracket, allowing the bracket to be pulled out for user access during maintenance. In some storage devices, the hard drive is positioned at the front (or pull-out) end of the bracket, the circuit board assembly at the rear (away from the pull-out end), and a cooling fan is positioned between the hard drive and the circuit board assembly. The cooling fan allows cooling airflow to enter from the front and exit from the rear of the bracket. In practical use, pulling the bracket out of the housing creates a cantilever structure, posing a significant risk of tipping if the extended length is large. Furthermore, the pull-out mechanism (such as rails or channels) between the bracket and housing experiences significant torque after extension, increasing the risk of failure. Additionally, using a pull-out mechanism with higher strength would significantly increase procurement (or manufacturing) costs, reducing the chassis's market competitiveness. Furthermore, in practical applications, storage devices are arranged in rows in the data center, with aisles formed between two rows to facilitate user access. However, during maintenance, the length of the extended support after fully pulling it out of the enclosure must not exceed the width of the aisle. Therefore, the minimum width of the aisle often depends on the maximum extended length of the support, which is not conducive to minimizing the aisle's size and improving the space utilization of the data center.

[0024] Based on the aforementioned problems with current storage devices, this application provides a chassis that can reduce the length of the support bracket pull-out.

[0025] To clearly understand the technical solution of this application, the chassis provided in this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0026] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” and “one or more” refer to one, two, or more than two. The term “and / or” is used to describe the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can indicate: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0027] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0028] like Figure 1 As shown in one embodiment of this application, the structure of the top of the housing 11 is omitted to clearly illustrate the structure of the bracket 12. The housing 10 includes a housing 11 and a bracket 12 located within the housing 11; the bracket 12 includes a first receiving compartment 121 and a second receiving compartment 122 for accommodating electrical components, and the bracket 12 is bidirectionally pull-out within the housing 11. Specifically, as... Figure 2 As shown, the bracket 12 can be pulled out from the first end (or front end) of the housing 11. When the bracket 12 is pulled out, the first receiving compartment 121 is exposed outside the housing 11, allowing the user to perform maintenance and other tasks on the electrical components housed within the first receiving compartment 121. Additionally, as... Figure 3 As shown, the bracket 12 can also be pulled out from the second end (or rear end) of the housing 11. When the bracket 12 is pulled out from the second end of the housing 11, the second receiving compartment 122 is exposed outside the housing 11, allowing the user to perform maintenance and other tasks on the electrical components housed within it. This arrangement effectively reduces the length of the bracket 12 that can be pulled out. Specifically, if the length of the first receiving compartment 121 is L1 and the length of the second receiving compartment 122 is L2, the sum of the lengths of the first and second receiving compartments 121 is L1 + L2 = L3. If the housing 10 adopts the above bidirectional pull-out method, the maximum length of the bracket 12 that can be pulled out is no greater than L1 or L2, and less than L3. Therefore, when the bracket 12 is pulled out, it will not generate a large torque on the pull-out structure between the bracket 12 and the housing 11, thus helping to reduce the manufacturing or procurement costs of the pull-out structure and improving the market competitiveness of the housing 11. This allows the bracket 12 to accommodate more electrical components. Furthermore, in practical applications, since the maximum length of the bracket 12 that can be pulled out is effectively reduced, the distance between two oppositely placed cabinets 11 (such as two cabinets 11 with their front ends facing each other) can be effectively reduced when multiple cabinets 11 are placed together in application sites such as computer rooms, thereby improving the space utilization rate of application sites such as computer rooms. Electrical components can be hard drives or computing blades, etc., and this embodiment of the invention does not limit this.

[0029] In practice, the length of the first receiving compartment 121 and the length of the second receiving compartment 122 can be the same or different.

[0030] For example, in one embodiment provided in this application, the length of the first receiving compartment 121 is the same as the length of the second receiving compartment 122. A fan compartment 123 is provided between the first receiving compartment 121 and the second receiving compartment 122, and the first receiving compartment 121 and the second receiving compartment 122 are symmetrically arranged about the fan compartment 123. The fan compartment 123 can accommodate a cooling fan; please refer to the relevant documentation. Figure 4 When the bracket 12 is not pulled out of the housing 11, the airflow generated by the cooling fan can enter from the front end of the housing 11 and exit from the rear end of the housing 11. Alternatively, in some embodiments, the airflow generated by the cooling fan can also enter from the rear end of the housing 11 and exit from the front end of the housing 11, thereby enabling heat dissipation for the electrical components in the first housing compartment 121 and the second housing compartment 122.

[0031] In some embodiments, a receiving compartment for accommodating electrical components may be provided between the periphery of the bracket 12 and the inner wall of the housing 11. For example, in one embodiment provided in this application, an auxiliary receiving compartment 124 is provided between the periphery of the bracket 12 and the inner wall of the housing 11. Taking a storage device as an example, in a specific application, a circuit board assembly can be disposed in the auxiliary receiving compartment 124. The circuit board assembly can be fixed to the periphery of the bracket 12 or to the inner wall of the housing 11. Alternatively, some components in the circuit board assembly can be fixed to the periphery of the bracket 12, while other components can be fixed to the inner wall of the housing 11. The circuit board assembly and the hard drive can be electrically connected via a cable.

[0032] In practice, the location of the auxiliary storage compartment 124 can be reasonably selected based on the shape of the box 11 and the support 12, the location of the pull-out structure, etc.

[0033] For example, such as Figure 2 and Figure 3As shown, in one embodiment provided in this application, the housing 11 can be a rectangular shell structure with both front and rear ends open, and the support 12 can be a rectangular cubic frame structure. The left side of the support 12 and the left side wall of the housing 11 are connected by a pull-out structure (not shown in the figure), and the right side of the support 12 and the right side wall of the housing 11 are connected by a pull-out structure (not shown in the figure). The support 12 can be pulled out from the front end of the housing 11 or from the rear end of the housing 11. The first receiving compartment 121, the fan compartment 123, and the second receiving compartment 122 are arranged sequentially from the front end to the rear end of the support 12. The auxiliary receiving compartment 124 is disposed in the gap between the lower side of the support 12 and the bottom wall of the housing 11, thereby increasing the utilization rate of the space in the chassis 10. In other embodiments, the structural shapes of the housing 11 and the support 12 are not limited to the rectangular structures described above. For example, the housing 11 can also be a cylindrical structure with a circular, triangular, or other polygonal cross-section. The housing 11 can be a cubic structure with a spherical, trapezoidal, or other similar shapes. Furthermore, the structure of the channel formed in the housing 11 can be varied. For example, the channel can be straight or curved, etc. This application does not impose any specific limitations on this.

[0034] The heat dissipation process inside chassis 10 will be explained in detail below.

[0035] like Figure 4 As shown, when the bracket 12 is not pulled out of the housing 11, under the action of the cooling fan 20, the cooling airflow (represented by the thick solid line with arrows in the figure) enters the housing 11 from the front end and exits the housing 11 from the rear end. During this process, the airflow flows sequentially through the first receiving chamber 121, the fan chamber 123, and the second receiving chamber 122, thereby providing heat dissipation for the electrical components installed in the first receiving chamber 121 and the second receiving chamber 122.

[0036] In some embodiments, to allow the airflow generated by the cooling fan 20 to also flow through the auxiliary receiving chamber 124, in one embodiment provided in this application, a baffle 111 is provided in the middle of the auxiliary receiving chamber 124 (or below the fan chamber 123), dividing the auxiliary receiving chamber 124 into a third receiving chamber 1241 and a fourth receiving chamber 1242. The third receiving chamber 1241 is located below the first receiving chamber 121, and the first receiving chamber 121 has a first connecting port (not shown in the figure), through which the first receiving chamber 121 and the third receiving chamber 1241 can communicate. The fourth receiving chamber 1242 is located below the second receiving chamber 122, and the second receiving chamber 122 has a second connecting port (not shown in the figure), through which the second receiving chamber 122 and the fourth receiving chamber 1242 can communicate. Specifically, under the action of the cooling fan 20, the cooling airflow enters the housing 11 from the front end of the housing 11 and exits the housing 11 from the rear end of the housing 11. During this process, when the bracket 12 is not slid out of either end of the chassis, the airflow has two paths. The first path flows sequentially through the first receiving compartment 121, the fan compartment 123, and the second receiving compartment 122; the second path flows sequentially through the third receiving compartment 1241, the first connecting port, the fan compartment 123, the second connecting port, and the fourth receiving compartment 1242. This structural arrangement allows the cooling airflow generated by the cooling fan 20 to effectively flow through the first receiving compartment 121, the second receiving compartment 122, the third receiving compartment 1241, and the fourth receiving compartment 1242, thereby enabling the chassis 10 to have good heat dissipation capabilities. Specifically, the first receiving compartment 121 has a first connecting port on its side wall, and the second receiving compartment 122 has a second connecting port on its side wall; or, the first receiving compartment 121 has a first connecting port at its bottom, and the second receiving compartment 122 has a second connecting port at its bottom; or, one connecting port is on the side wall, and one connecting port is at the bottom. This embodiment of the invention does not limit this.

[0037] Additionally, when maintaining the electrical components within the first and second compartments 121 and 122, the bracket 12 needs to be pulled outwards. To maintain the heat dissipation capacity of the chassis 10, in one embodiment provided in this application, the chassis 11 also includes an anti-backflow plate 112.

[0038] Specifically, such as Figure 5As shown, when the bracket 12 is pulled out from the front end of the housing 11, the anti-backflow plate 112 inside the housing 11 blocks the rear end of the second receiving chamber 122, allowing the cooling airflow to exit from the rear end of the fourth receiving chamber 1242. Specifically, when the bracket 12 is pulled out from the front end of the housing 11, under the action of the cooling fan 20, the airflow enters from the front end of the first receiving chamber 121, flows through the first receiving chamber 121, the fan chamber 123, and the second receiving chamber 122, then through the channel and the fourth receiving chamber 1242 before exiting from the rear end. When the user pulls out the bracket 12 to maintain the electrical components in the first receiving chamber 121, the airflow generated by the cooling fan 20 can still flow well through the first receiving chamber 121 and the second receiving chamber 122, thus effectively ensuring continuous heat dissipation. In specific implementations, the anti-backflow plate 112 can be set in various ways. For example, the top of the anti-backflow plate 112 can be fixed to the inner top wall of the housing 11 by a pin. Under the action of gravity, the anti-backflow plate 112 tends to flip downwards, so that when the support 12 is pulled out from the front end of the housing 11, the anti-backflow plate 112 can flip downwards under its own gravity. In addition, in some embodiments, to improve the reliability of the anti-backflow plate 112, an elastic element can be provided. For example, an elastic element such as a torsion spring can be sleeved around the pin. One end of the torsion spring can be connected to the housing 11, and the other end can be connected to the anti-backflow plate 112. Under the elastic force of the torsion spring, the anti-backflow plate 112 tends to flip downwards, thereby blocking the rear end of the second receiving chamber 122. In other embodiments, when the support 12 is pulled out from the front end of the housing 11, in order to block the rear end of the second receiving chamber 122 and allow the cooling airflow to flow through the fourth receiving chamber 1242, other mechanical structures can also be used to block the rear end of the second receiving chamber 122. This application does not specifically limit this.

[0039] Additionally, as shown in the figure, when the bracket 12 is pulled out from the rear end of the housing 11, the first connecting port is positioned to connect with the fourth receiving compartment 1242, thus connecting the first receiving compartment 121 and the fourth receiving compartment 1242. Under the action of the cooling fan 20, a portion of the cooling airflow enters the first receiving compartment 121 from the front end of the housing 11 through the channel, then flows through the fan compartment 123 to the second receiving compartment 122 before being discharged. Another portion of the cooling airflow enters the fourth receiving compartment 1242 from the rear end of the housing 11, enters the first receiving compartment 121 through the first connecting port, and finally flows through the fan compartment 123 to the second receiving compartment 122 before being discharged. When the user pulls out the bracket 12 to maintain the electrical components in the second receiving compartment 122, the airflow generated by the cooling fan 20 can still flow well through the first receiving compartment 121 and the second receiving compartment 122, thereby effectively ensuring continuous heat dissipation.

[0040] On the other hand, in practical applications, the chassis 10 can be used in various electronic devices such as network devices and storage devices.

[0041] For example, the storage device may include any of the chassis 10 described in the above embodiments. A cooling fan 20 is installed in the fan compartment 123 of the chassis 10, and hard drives are installed in the first receiving compartment 121 and the second receiving compartment 122. Furthermore, the storage device may also include a circuit board assembly, which may be disposed in an auxiliary receiving compartment 124. In specific implementations, the circuit board assembly can be arranged in various ways. For example, in one embodiment provided in this application, the circuit board assembly may include a control board and / or a power module. The circuit board assembly can be electrically connected to the hard drives in the first receiving compartment 121 and / or the second receiving compartment 122 via cables. Please refer to [reference needed]. Figure 7 To increase cable reliability, in one embodiment of this application, the circuit board assembly is installed in an auxiliary receiving compartment 124. The auxiliary receiving compartment 124 is equipped with a tank chain 30, one end of which is fixedly connected to a bracket 12, and the other end is fixedly connected to a housing 11. Cables are installed on the tank chain 30. When the bracket 12 slides relative to the housing 11, the tank chain 30 provides good protection for the cables, preventing tangling, wear, pull-out, and other defects. In another implementation, the circuit board assembly can be fixed to the inner bottom wall or inner side of the housing 11. When the circuit board assembly is not in the auxiliary receiving compartment, but is electrically connected to the hard drive via a cable, the tank chain can still be used, with the cables installed on it. One end of the tank chain is connected to the housing, and the other end is fixedly connected to a bracket in the housing.

[0042] In another embodiment, the chassis 10 can be used in a computing device, with computing blades installed in the first and second receiving compartments 121 and 122, and a cooling fan 20 installed in the fan compartment 123. Furthermore, the computing device may also include a circuit board assembly, which can be disposed in an auxiliary receiving compartment 124. In specific implementations, the circuit board assembly can be arranged in various ways. For example, in one embodiment provided in this application, the circuit board assembly may include a control board and / or a power module. The circuit board assembly can be electrically connected to the computing blades in the first and / or second receiving compartments 121 and 122 via cables. Please refer to [further details needed]. Figure 7To increase cable reliability, in one embodiment of this application, the circuit board assembly is installed in an auxiliary receiving compartment 124. The auxiliary receiving compartment 124 is equipped with a tank chain 30, one end of which is fixedly connected to a bracket 12, and the other end is fixedly connected to a housing 11. Cables are installed on the tank chain 30. When the bracket 12 slides relative to the housing 11, the tank chain 30 provides good protection for the cables, preventing tangling, wear, pull-out, and other adverse phenomena. In another implementation, the circuit board assembly can be fixed to the inner bottom wall or inner side of the housing 11. A control board can be used to manage the computing device. When the circuit board assembly is not in the auxiliary receiving compartment, but is electrically connected to the computing blades via cables, the tank chain can still be used to install cables on it. One end of the tank chain is connected to the housing, and the other end is fixedly connected to a bracket in the housing.

[0043] In another embodiment, the chassis 10 can be used in a fusion device. One of the first and second accommodating bays 121 and 122 houses a computing blade, while the other bay houses a hard drive. A cooling fan 20 is installed in the fan bay 123. Furthermore, the fusion device may also include a circuit board assembly, which can be disposed within an auxiliary accommodating bay 124. In specific implementations, the circuit board assembly can be arranged in various ways. For example, in one embodiment provided in this application, the circuit board assembly may include a control board and / or a power module. The circuit board assembly can be electrically connected to the computing blade and hard drive in the accommodating bay via cables. Please refer to [further details needed]. Figure 7 To increase cable reliability, in one embodiment of this application, the circuit board assembly is installed in an auxiliary receiving compartment 124. The auxiliary receiving compartment 124 is equipped with a tank chain 30, one end of which is fixedly connected to a bracket 12, and the other end is fixedly connected to a housing 11. Cables are mounted on the tank chain 30. When the bracket 12 slides relative to the housing 11, the tank chain 30 provides good protection for the cables, preventing tangling, wear, and pull-out. In one implementation, the circuit board assembly can be fixed to the inner bottom wall or inner side of the housing 11. The circuit board assembly can be used to manage the fusion device. In another implementation, the circuit board assembly can be electrically connected to a hard drive or computing blade in the receiving compartment via a cable. When the circuit board assembly is not in the auxiliary receiving compartment, but is electrically connected to the hard drive or computing blade via a cable, the tank chain can still be used, with the cable mounted on it. One end of the tank chain is connected to the housing, and the other end is fixedly connected to a bracket in the housing.

[0044] In another implementation, the computing blades in this embodiment of the invention can be replaced with other electrical components such as processors, and the hard disks can be replaced with electrical components such as storage blades. This embodiment of the invention does not limit this.
