Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a storage device. Background Art

[0002] With the continuous development and deepening of informatization, the continuous growth of data has driven the development of data storage devices. The number of hard disks in storage devices is required to be more and more, that is, the density requirement of hard disks is becoming more and more obvious, so as to enhance the ability of storage devices to store and calculate data. At present, the storage capacity of storage devices is mainly improved by increasing the storage capacity of a single hard disk or increasing the density of hard disks in a unit volume of the storage device.

[0003] When the density of hard disks in a unit volume of the storage device is increased to meet the storage capacity of the storage device, it is necessary to accommodate a larger number of hard disks in a limited chassis, that is, to combine multiple independent hard disks in different ways to form a hard disk group, so as to provide higher storage performance than a single hard disk and provide data backup technology.

[0004] In related technologies, hard disks have relatively strict temperature requirements, generally the temperature cannot be higher than 60°C. Due to heat convection, hot air rises and easily accumulates above and at the rear end of the array of hard disks, resulting in the heat of the array of hard disks being concentrated at the edges and the rear row, and the heat dissipation effect is poor. Summary of the Invention

[0005] The present invention provides a storage device to solve at least one of the above technical defects. When a hard disk is inserted into the slide member, high-pressure air can be introduced into the hard disks at the rear end of the slide member through the first air duct, increasing the air velocity between the hard disks at the rear end of the slide member, thereby reducing the temperature of the hard disks at the rear end of the slide member and improving the heat dissipation effect of the array of hard disks.

[0006] A storage device provided by the present invention includes a chassis assembly. One end of the chassis assembly is configured with an air inlet, and the other end is configured with an air outlet; the chassis assembly includes a housing member, a slide member, and a central component;

[0007] The central component is disposed at one end of the slide member, and includes a central frame body and a power module, a main control module, and a fan module disposed on the central frame body. The fan module is disposed between the power module and the main control module;

[0008] The housing component is disposed outside the slideway component and the central component, and includes two side plates and a top plate which are oppositely arranged. The top plate is respectively connected to each side plate. The side plates, the slideway component and the top plate enclose a first air duct, and the first air duct is respectively communicated with the air inlet and the air outlet. The ventilation area of the first air duct relatively close to the air inlet is larger than the ventilation area of the first air duct relatively close to the air outlet.

[0009] The storage device provided by the present invention forms a first air duct by enclosing the side plates, the slideway component and the top plate. The first air duct is respectively communicated with the air inlet and the air outlet. The ventilation area of the first air duct relatively close to the air inlet is larger than the ventilation area of the first air duct relatively close to the air outlet. In this way, it is equivalent to having a blocking surface at the position of the first air duct close to the air outlet end, so that the ventilation area at the position of the first air duct close to the air outlet end is reduced. According to the Venturi effect, when the air flow blows through the blocking surface of the first air duct, the air pressure is relatively low near the upper port on the leeward side of the blocking surface, thereby generating an adsorption effect and causing the air to flow. That is, it is equivalent to the air flow changing from thick to thin to accelerate the air flow rate, that is, to increase the wind speed, so as to quickly discharge the air flow and avoid accumulation at the rear end of the first air duct. When the hard disk is inserted into the slideway component, the high-pressure air flow can be introduced into the hard disk at the rear end of the slideway component through the first air duct, increasing the wind speed between the hard disks at the rear end of the slideway component, thereby reducing the temperature of the hard disks at the rear end of the slideway component and improving the heat dissipation effect. It effectively solves the problem that due to heat convection, the hot air floats upward and is easy to accumulate above and at the rear end of the array hard disks, resulting in the heat of the array hard disks being concentrated at the edges and the rear rows, and the heat dissipation effect is poor.

Detailed implementation manners

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Large-disk storage devices usually refer to devices with more than 100 hard disks and a 4U height. The design difficulty of large-disk storage devices lies mainly in: how to place more hard disks within a 4U height and with a certain chassis length; how to ensure chassis strength when the full configuration weight exceeds 130kg; how to ensure the assembly accuracy between chassis components. In addition, since there are many replacement requirements for components in large-disk storage devices, how to replace each component more conveniently and quickly, while taking into account the assembly accuracy between each component, to facilitate hard disk installation. In view of the above difficulties, an embodiment of the present invention provides a storage device.

[0040] See also Figures 1 to 6 The embodiment of the present invention provides a storage device, which includes a chassis component 100 and a hub component 150. The chassis component 100 serves as the main body and appearance display of the storage device and is used to carry a hard disk 200. In this embodiment, the total length of the chassis component 100 is 1013.5 mm, the total width is 434.8 mm, and the total height is 176 mm.

[0041] The chassis assembly 100 includes a shell component 110, a slide component 120 and a hard disk carrier 130. The hard disk carrier 130 is detachably connected to the bottom of the slide component 120 by means of fasteners such as snap-fitting and screws, so that the hard disk carrier 130 and the slide component 120 enclose a plurality of first installation cavities 140 for accommodating hard disks 200, that is, a hard disk 200 is placed in each first installation cavity 140. For example, the slide component 120 and the hard disk carrier 130 enclose 7 rows of cavities for installing multiple hard disks 200, and each cavity is longitudinally provided with 15 columns of first installation cavities 140. In this way, 105 pcs of hard disks 200 can be installed in the installation space enclosed by the slide component 120 and the hard disk carrier 130, so that the storage device meets the requirements of large disk storage. The shell component 110 is arranged on the outside of the slide component 120 and the hard disk carrier 130, which is equivalent to the shell component 110 being wrapped around the outside of the slide component 120 and the hard disk carrier 130. The shell component 110 serves as the appearance finish of the storage device.

[0042] The central component 150 is located at the rear end of the slide member 120. The housing member 110 is disposed outside the central component 150 and is detachably connected to the central component 150. The central component 150 is used to collect and process information of the hard disk 200, and at the same time ensure the power supply and heat dissipation of the entire storage device.

[0043] The central component 150 includes a central frame 151 for carrying various components. The central frame 151 is configured with a first receiving groove 1511, a second receiving groove 1512, and a third receiving groove 1513. The first receiving groove 1511 is used to install the power module 152, the second receiving groove 1512 is used to install the main control module 153 and the sub-card module 154, and the third receiving groove 1513 is used to install the fan module 155.

[0044] The first receiving groove 1511 and the second receiving groove 1512 are located on both sides of the third receiving groove 1513. The groove walls of the first receiving groove 1511, the second receiving groove 1512, and the third receiving groove 1513 define a second installation cavity 1514 for receiving the hard disk 200. That is, the first receiving groove 1511 and the second receiving groove 1512 are arranged along the width direction of the central frame 151, and the first receiving groove 1511 and the second receiving groove 1512 are located on both sides of the central frame 151. In this way, when the power module 152 is installed in the first receiving groove 1511 and the main control module 153 and the sub-card module 154 are installed in the second receiving groove 1512, the two components that are prone to heat generation are separated to avoid heat interference between the two components.

[0045] In some embodiments of the present invention, the second receiving groove 1512 includes a first sub-groove 1512-1 and a second sub-groove 1512-2 that are spaced apart. The first sub-groove 1512-1 is adjacently arranged to the third receiving groove 1513 and the second installation cavity 1514; the first sub-groove 1512-1 is used to install the sub-card module 154, and the second sub-groove 1512-2 is used to install the main control module 153. Here, equivalently, the sub-card module 154 and the main control module 153 are separately arranged. Of course, the sub-card module 154 and the main control module 153 can also be centrally arranged in the same slot. By independently arranging each component, independent plugging and unplugging of each component can be achieved.

[0046] Correspondingly, in addition to a power slot, a main control slot, a sub-card slot, and a fan slot provided in the central frame 151, there is also a hard disk slot that can accommodate 9 pcs of hard disks 200, that is, the second installation cavity 1514. Among them, the width of the first accommodation slot 1511 for installing the power module 152 is 185 mm, and the length is 73.5 mm. There are four groups of power modules 152; the width of the third accommodation slot 1513 for installing the fan module is 40 mm, the length is 80 mm, and the height is 240 mm. That is, the height of the fan module is 240 mm. There are three groups of fan modules. The width difference between the first accommodation slot 1511 and the third accommodation slot 1513 is 145 mm. This width difference is the width of the second installation cavity 1514 for vertically placing the hard disk 200. That is, the sum of the widths of the third accommodation slot 1513 and the second installation cavity 1514 is equal to the width of the first accommodation slot 1511. If the thickness of the hard disk 200 is set to 26 mm, then 9 pcs of hard disks 200 can be arrayed and accommodated in the second installation cavity 1514. In this way, adding the 105 pcs of hard disks 200 in the first installation cavity 140 mentioned above, the number of hard disks 200 that the entire storage device can accommodate is 114 pcs, realizing the setting of a storage device with a large number of disk positions.

[0047] It can be understood that for the storage device provided by the embodiment of the present invention, by arranging the central component at the rear end of the chassis component and arranging the fan module of the central component between the power module and the main control module, adopting this layout method can not only improve the utilization rate of the internal space of the storage device, so that the storage device can accommodate more hard disks under the 4U height, but also improve the heat dissipation efficiency of the storage device.

[0048] Furthermore, by detachably connecting the hard disk carrier 130 to the bottom of the slideway component 120, the hard disk carrier 130 and the slideway component 120 enclose a plurality of first installation cavities 140 for installing hard disks 200. The housing component 110 is arranged outside the slideway component 120 and the hard disk carrier 130, which is equivalent to the housing component 110 wrapping outside the slideway component 120 and the hard disk carrier 130. In this way, the hard disk carrier 130 is directly connected to the slideway component 120 to form the first installation cavity 140, which can ensure the accurate position of the connector 170 on the hard disk carrier 130 for connecting with the hard disk 200, facilitate the smooth installation of the hard disk 200, and improve the assembly efficiency of the storage device. It can avoid the problem that due to the processing and assembly errors between the slideway component 120 and the hard disk carrier 130, the connector 170 of the hard disk carrier 130 is offset, so that the interface of the hard disk 200 and the connector 170 cannot be aligned for smooth installation.

[0049] When the hard disk carrier 130 and the hard disk 200 slide are indirectly installed on the chassis, there are at least two assembly processes, that is, the assembly between the hard disk carrier 130 and the chassis, and the assembly between the hard disk 200 slide and the chassis. Each assembly will generate corresponding assembly errors, and the cumulative assembly errors will cause the connector 170 of the hard disk carrier 130 to be offset, making it impossible to install the hard disk 200 smoothly. However, for the storage device provided by the embodiment of the present invention, since the hard disk carrier 130 is directly connected to the slide member 120 and does not rely on the chassis for assembly, therefore, it is equivalent to only one assembly process between the hard disk carrier 130 and the slide member 120. In this way, compared with the prior art, one assembly process is reduced, and the corresponding assembly errors can be avoided, so as to prevent the connector 170 of the hard disk carrier 130 from being offset and making it impossible to install the hard disk 200 smoothly.

[0050] Refer to Figure 2 and Figure 3 In some embodiments of the present invention, one of the slide member 120 and the hard disk carrier 130 is provided with a positioning portion 121, and the other of the slide member 120 and the hard disk carrier 130 is provided with a mating portion 131 that cooperates with the positioning portion 121 for positioning. By the cooperation of the positioning portion 121 and the mating portion 131 for positioning, the assembly accuracy and assembly efficiency between the slide member 120 and the hard disk carrier 130 can be further improved, and the corresponding assembly errors generated during the assembly of the slide member 120 and the hard disk carrier 130 can be avoided, so as to prevent the connector 170 of the hard disk carrier 130 from being offset and making it impossible to install the hard disk 200 smoothly.

[0051] Among them, the positioning portion 121 can be a protrusion, such as a convex point, a convex platform or a convex column, and the mating portion 131 can be a groove that cooperates with the protrusion. Before fastening, the installation positions of the slide member 120 and the hard disk carrier 130 are first limited by the cooperation of the protrusion and the groove, which is convenient for connecting the slide member 120 and the hard disk carrier 130.

[0052] In some embodiments, the positioning portion 121 can be provided on the slide member 120, and the mating portion 131 that cooperates with the positioning portion 121 for positioning can be provided on the hard disk carrier 130.

[0053] In some embodiments, the mating portion 131 can be provided on the slide member 120, and the positioning portion 121 that cooperates with the mating portion 131 for positioning can be provided on the hard disk carrier 130.

[0054] In some embodiments, the positioning portion 121 and the mating portion 131 can be simultaneously provided on the slide member 120, the mating portion 131 that cooperates with the positioning portion 121 for positioning can be provided on the hard disk carrier 130, and the positioning portion 121 that cooperates with the mating portion 131 for positioning can be provided on the hard disk carrier 130.

[0055] Referring to Figure 4 , in some embodiments of the present invention, the slideway component 120 includes a plurality of slideway brackets 122 and a connecting member 123.

[0056] The connecting member 123 is located between two adjacent slideway brackets 122 and is detachably connected to the two adjacent slideway brackets 122 respectively, so as to form an installation groove between the two adjacent slideway brackets 122. The hard disk carrier 130 is detachably connected to the plurality of slideway brackets 122 to close one end of the installation groove and form a first installation cavity 140.

[0057] That is to say, the plurality of slideway brackets 122 are all arranged at intervals, and two adjacent slideway brackets 122 are connected by the connecting member 123. In this way, not only is it convenient to process a single slideway bracket 122, but also when one of the slideway brackets 122 is damaged, the damaged slideway bracket 122 can be removed accordingly, without replacing the entire slideway component 120, which can save maintenance costs. In addition, by setting the slideway component 120 as a plurality of slideway brackets 122, the number of slideway brackets 122 can be adjusted accordingly according to the size requirements of the storage device, so that the storage device has stronger adaptability.

[0058] For example, in the embodiments of the present application, a total of 8 columns of slideway brackets 122 are provided, and two adjacent columns of slideway brackets 122 are arranged at intervals. One side of the connecting member 123 is detachably connected to one of the slideway brackets 122 through fasteners such as rivets and screws, and the other side of the connecting member 123 is detachably connected to another slideway bracket 122 through fasteners such as rivets and screws.

[0059] Wherein, the connecting member 123 is made of sheet metal. The connecting member 123 can be set in a grid shape, or can be formed by nesting a plurality of "U"-shaped sheet metal parts, as long as it is convenient for heat dissipation, and any sheet metal part structure between two adjacent slideway brackets 122 is acceptable.

[0060] The connecting member 123 made of sheet metal can be integrally formed and cut into a plurality of frame bars. The connecting member 123 made of sheet metal can also be separately arranged. For example, it includes a connecting body and connecting plates connected to both sides of the connecting body. The connecting body and the connecting plates are fixedly connected by welding, and connecting holes are formed in the connecting plates, and the connecting plates are detachably connected to the slideway brackets 122 through the connecting holes.

[0061] Continuing to refer to Figure 4 , in order to improve the structural strength of the slideway component 120, and at the same time facilitate the installation of the slideway component 120 and avoid interference during the installation of the connecting member 123, the connecting members 123 located in two adjacent installation grooves are arranged in a staggered manner.

[0062] For example, the connecting member 123 of one of the mounting grooves is located at positions near both ends of the slideway bracket 122, and the connecting member 123 of another mounting groove adjacent to this mounting groove is located at a position near the middle of the slideway bracket 122.

[0063] Alternatively, the connecting members 123 of one of the mounting grooves are arranged at equal intervals on the slideway bracket 122, and some of the connecting members 123 of another mounting groove adjacent to this mounting groove are located on the extension line of the center line between two adjacent connecting members 123 of this mounting groove. That is, when viewed from the top, the center points of the connecting members 123 in two adjacent mounting grooves form at least one virtual triangle, so that the stability of the slideway component 120 can be improved.

[0064] Among them, the number of connecting members 123 in two adjacent mounting grooves may be the same or different, and the number of connecting members 123 in each mounting groove is determined according to actual use conditions and is not limited herein.

[0065] Continue to refer to Figure 4 In some embodiments of the present invention, each slideway bracket 122 includes a slideway body 1221, and the slideway body 1221 is provided with a first side and a second side in the width direction. A first connecting portion 1222 is provided at the bottom of the slideway body 1221, and the first connecting portion 1222 extends from the surface of the slideway body 1221 to the first side and the second side respectively; second connecting portions 1223 are provided at both ends of the slideway body 1221, and the second connecting portions 1223 extend from the surface of the slideway body 1221 to the first side and the second side respectively. Among them, the hard disk carrier 130 is connected to the first connecting portion 1222, and the housing component 110 is connected to the second connecting portion 1223.

[0066] That is, a first connecting portion 1222 for connecting the hard disk carrier 130 is provided on the slideway body 1221, and a second connecting portion 1223 for connecting the housing component 110 is provided on the slideway body 1221, so that the functions of each part of the slideway bracket 122 can be independently realized, and it is possible to avoid multiple components being concentratedly connected at the same position of the slideway bracket 122, so as to prevent the slideway bracket 122 from being damaged due to stress concentration.

[0067] Moreover, by extending the first connecting portion 1222 on the slideway body 1221 and extending the second connecting portion 1223 on the slideway body 1221, connecting the hard disk carrier 130 through the first connecting portion 1222 extending from the slideway body 1221, and connecting the housing component 110 through the second connecting portion 1223 extending from the slideway body 1221, sufficient installation space can be reserved for the installation of the hard disk carrier 130 and the housing component 110, which is convenient for the assembly of the hard disk carrier 130 and the housing component 110, and further improves the assembly efficiency of the storage device.

[0068] Continue to refer toFigure 4 In some embodiments of the present invention, the thickness of the outermost slide rail bracket 122 is less than the thickness between the middle slide rails. For the outermost slide rail bracket 122, its first connecting portion 1222 extends from the surface of the slide rail body 1221 to the first side or the second side, and its second connecting portion 1223 extends from the surface of the slide rail body 1221 to the first side or the second side.

[0069] That is to say, for the outermost slide rail bracket 122, the first connecting portion 1222 and the second connecting portion 1223 are provided on only one side, and both the first connecting portion 1222 and the second connecting portion 1223 face another slide rail bracket 122 adjacent to the outermost slide rail bracket 122. The first connecting portion 1222 and the second connecting portion 1223 are provided on both sides of the middle slide rail bracket 122.

[0070] For example, the slide rail bracket 122 includes a first slide rail component 1226 and a second slide rail component 1227. There are multiple first slide rail components 1226, and two adjacent first slide rail components 1226 are spaced apart to form an installation groove. The second slide rail component 1227 is located on both sides of all the first slide rail components 1226, and an installation groove is also formed between the second slide rail component 1227 and the first slide rail component 1226.

[0071] Since both sides of the first slide rail component 1226 need to connect the hard disk carrier 130 and the housing component 110, and carry the hard disk 200, the strength of the first slide rail component 1226 needs to be greater than that of the second slide rail component 1227. Therefore, the thickness of the first slide rail component 1226 can be set to be greater than the thickness of the second slide rail component 1227. For example, the thickness of the first slide rail component 1226 is 2 mm, while the thickness of the second slide rail component 1227 is 1 mm, which is equivalent to that the second slide rail component 1227 is provided with a single-layer slide rail body 1221, and the first slide rail component 1226 is provided with a double-layer slide rail body 1221, that is, the first slide rail component 1226 is formed by riveting two layers of slide rail bodies 1221.

[0072] In some embodiments of the present invention, when the total length of the chassis assembly 100 is 1013.5 mm, the total width is 434.8 mm, and the total height is 176 mm, the width of the installation groove can be 108.6 mm, that is, the distance between two adjacent slide rail brackets 122 is 108.6 mm, and the total length of the entire slide rail component 120 is 776.2 mm.

[0073] Continue to refer to Figure 4, in some embodiments of the present invention, each slide bracket 122 is provided with a ventilation opening 1224, and the position of the ventilation opening 1224 corresponds to the installation position of the hard disk 200. That is, a plurality of ventilation openings 1224 are arranged in an array on the slide body 1221 of each slide bracket 122 to enable air circulation in the slide component 120 and facilitate heat dissipation of the hard disk 200 installed in the slide component 120.

[0074] Among them, the ventilation opening 1224 can be a groove structure, and the width of the ventilation opening 1224 is greater than the width of the hard disk 200. After the hard disk 200 is installed in the installation groove, four-fifths of the area of the ventilation opening 1224 is blocked by the hard disk 200, and one-fifth of the area of the ventilation opening 1224 can allow air to flow through, so as to form an air duct between two adjacent hard disks 200 and facilitate heat dissipation of the hard disk 200.

[0075] Continue to refer to Figure 4 , in some embodiments of the present invention, a flange portion 1225 extends outward from the edge of the ventilation opening 1224; a slideway is formed between the flange portions 1225 of the ventilation openings 1224 of two adjacent slide brackets 122, and the hard disk 200 is inserted into the slideway.

[0076] Equivalently, the flange portion 1225 protrudes outward along the edge of the through-opening so that the surface of the flange portion 1225 is higher than the surface of the slide body 1221. In this way, when the hard disk 200 abuts against the flange portion 1225, a ventilation gap is left between the hard disk 200 and the slide body 1221, which is convenient for heat dissipation of the hard disk 200.

[0077] Continue to refer to Figure 1 , and at the same time refer to Figure 5 , in some embodiments of the present invention, the housing component 110 includes a side plate 111, a bottom plate 112, a top plate 113, and a front panel 114.

[0078] The side plates 111 are respectively located on both sides of the slide component 120 and are detachably connected to the slide component 120. Specifically, the side plates 111 are detachably connected to the second connecting portion 1223 of the above-mentioned slide bracket 122 through fasteners such as rivets and screws. When maintenance or replacement is required, the side plates 111 can be disassembled to expose the slide brackets 122 of the slide component 120, which is convenient for after-sales maintenance of the slide component 120. In addition, a handle strip 1111 made of sheet metal is provided on the side plate 111 to facilitate disassembly of the side plate 111.

[0079] The bottom plate 112 is located at the bottom of the hard disk carrier 130. The bottom plate 112 is detachably connected to at least one of the slideway component 120 and the hard disk carrier 130. That is to say, the bottom plate 112 can be detachably connected to the first connecting portion 1222 of the above-mentioned slideway bracket 122 through fasteners such as rivets and screws. When the strength of the hard disk carrier 130 is sufficient to support the bottom plate 112, the bottom plate 112 can also be detachably connected to the hard disk carrier 130 through fasteners such as rivets and screws. A receiving cavity is defined between the bottom plate 112 and the hard disk carrier 130. This receiving cavity can be used for wiring. That is, the connecting cable between the hard disk carrier 130 and other components (such as the following function board 160) is located in this receiving cavity. In this way, when wiring, cable management, plugging and unplugging, and repairing the connecting cable are required, only the bottom plate 112 needs to be disassembled, and the operation is more convenient.

[0080] The top plate 113 is located at the top of the slideway component. The top plate 113 is detachably connected to the side plate 111. Refer to Figure 1 , there is a flange at the top of the side plate 111, connecting columns are provided on the flange, flanges are bent on both sides of the top plate 113, and a special-shaped chute is provided on the flange. When the top plate 113 is connected to the side plate 111, only the chute of the top plate 113 needs to be snapped onto the connecting column of the side plate 111. After being snapped in place, the chute can restrict the connecting column from coming out, so as to realize the connection between the top plate 113 and the side plate 111. There is no need to borrow auxiliary tools for installation, the connection is more convenient, and at the same time, it is convenient to disassemble the top plate 113. Of course, the connecting column can also be provided on the top plate 113, and the special-shaped chute is correspondingly provided on the flange of the side plate 111.

[0081] It should be noted that in addition to the above connection method between the top plate 113 and the side plate 111, other connection methods can also be adopted, such as, by means of snap connection or mechanical lock for connection.

[0082] The front panel 114 is located at the front end of the slideway component. The front panel 114 is detachably connected to at least one of the side plate 111 and the slideway component 120. For example, flanges are provided around the front panel 114. The front panel 114 can fix the flanges on both sides to the flange provided at the end of the side plate 111 through fasteners such as screws and rivets. The front panel 114 can connect the flange at the bottom to the first connecting portion 1222 of the above-mentioned slideway bracket 122 through fasteners such as screws and rivets. Of course, the front panel 114 can also be separately connected to the side plate 111 or the slideway component 120.

[0083] In an embodiment of the present invention, the slide member 120 and the side plate 111 are connected by riveting to form a cage main structure. The front panel 114 is installed at the front end of the main structure, the top plate 113 is installed at the top of the main structure, the hard disk carrier 130 is installed at the bottom of the main structure from bottom to top, and the bottom plate 112 is installed at the bottom of the main structure and is located below the hard disk carrier 130.

[0084] Continue to refer to Figure 1 and Figure 5 In some embodiments of the present invention, a support column 1121 is provided on one side of the bottom plate 112 facing the hard disk carrier 130. When the bottom plate 112 is connected to at least one of the slide member 120 and the hard disk carrier 130, the support column 1121 abuts against the hard disk carrier 130. For example, when the bottom plate 112 is connected to the slide member 120, the support column 1121 abuts against the lower surface of the hard disk carrier 130. In this way, not only can the structural strength between the bottom plate 112 and the hard disk carrier 130 be improved, but also the intermittent stability between the bottom plate 112 and the hard disk carrier 130 can be restricted by the support column 1121, avoiding local deformation of the bottom plate 112 to block the structure of the accommodation cavity, and at the same time, avoiding affecting the connection cables located in the accommodation cavity due to excessive deformation.

[0085] Continue to refer to Figure 1 and at the same time refer to Figure 7 In some embodiments of the present invention, the hard disk carrier 130 includes a first carrier portion 132 and a second carrier portion 133 connected to each other. The first carrier portion 132 is disposed corresponding to the first installation cavity 140, and the second carrier portion 133 is disposed corresponding to the second accommodation groove 1512; both the first carrier portion 132 and the second carrier portion 133 are provided with connectors 170 for connecting the hard disk 200 in an array.

[0086] That is to say, the hard disk carrier 130 is arranged corresponding to the position of the hard disk 200, and is provided from the front end to the rear end of the storage device. The hard disk carrier 130 is directly connected to the corresponding hard disk 200 through the connector 170.

[0087] Continue to refer to Figure 7, in some embodiments of the present invention, a third carrier part 134 is provided between the first carrier part 132 and the second carrier part 133. A functional board 160 is connected to the third carrier part 134. The functional board 160 is arranged at the end of the slideway component 120. During the installation process, the functional board 160 can be installed from the rear to the front, with a relatively large operating space and more convenient operation. The functional board 160 is respectively connected to the corresponding modules of the hard disk carrier 130 and the central component 150, and is used to enable communication between the hard disk carrier 130 and the central component 150. That is, the functional board 160 serves as a relay bridge between each hard disk 200 and the corresponding module of the central component 150. The functional board 160 is arranged close to the central component 150, which can shorten the cable length between the central component 150 and the functional board 160, ensure the data transmission quality, and avoid the problems of long signal transmission link and poor quality of the connecting cable.

[0088] For example, the functional board 160 is provided with a power interface and a signal interface. The power interface is connected to the power module 152, and the signal interface is connected to the main control module 153 and the daughter card module 154. The hard disk carrier 130 is connected to the functional board 160 through a connecting cable.

[0089] It should also be noted that the hard disk 200 includes a hard disk body, a handle, a rotating shaft, and a plastic fixing frame. The handle is fixed to the hard disk body through the rotating shaft. The plastic fixing frame surrounds the hard disk body. The hard disk body is clamped in the first installation cavity 140 of the slideway component 120 through the plastic fixing frame.

[0090] When installing the storage device provided by the embodiment of the present invention, first select the corresponding number of slideway brackets 122 according to needs, and connect two adjacent slideway brackets 122 with a connecting piece 123 to form a slideway component 120.

[0091] Then, connect the slideway component 120 and the side plate 111 by riveting to form a cage-like main structure. Install the front panel 114 at the front end of the main structure, install the top plate 113 at the top of the main structure. The hard disk carrier 130 is installed at the bottom of the main structure from bottom to top. Lock the screws or rivets from bottom to top. Then, insert one end of the connecting cable into the corresponding interface of the hard disk carrier 130, insert the other end of the connecting cable into the interface of the functional board 160, and then install the bottom plate 112 at the bottom of the main structure through screws and rivets and locate it below the hard disk carrier 130 to form an accommodation cavity between the bottom plate 112 and the hard disk carrier 130.

[0092] Then, the central component 150 is installed on the main structure of the chassis component 100 from the rear to the front and locked to the side plate 111 by screws and rivets. As an independent module, the central component 150 can be disassembled independently. Finally, the power module 152, the fan module 155 and the main control module 153 are installed in the corresponding receiving grooves, and the corresponding number of hard disks 200 are installed according to requirements, and then the top plate 113 is buckled.

[0093] For the storage device provided by the embodiment of the present invention, by detachably connecting the hard disk carrier 130 to the bottom of the slideway component 120, the hard disk carrier 130 and the slideway component 120 enclose a plurality of first installation cavities 140 for installing the hard disks 200. Abandoning the traditional way of installing the hard disk carrier 130 on the chassis base, when the hard disk 200 is installed in the first installation cavity 140, it is possible to avoid the problem that the connector 170 of the hard disk carrier 130 is offset due to the processing and assembly errors between the slideway component 120 and the hard disk carrier 130, resulting in the misalignment of the interface of the hard disk 200 and the connector 170 and thus preventing smooth installation, thereby improving the assembly efficiency and assembly accuracy. And since the slideway component 120 is riveted to the housing component 110 of the chassis component 100, the chassis component 100 can be split into multiple independent parts, which facilitates the repair and replacement of the corresponding parts.

[0094] In addition, for the storage device provided by the embodiment of the present invention, when the hard disk carrier 130 is connected to the corresponding module of the central component 150, it is connected by using a connection cable through an independent wiring space without using an adapter board. Since the connection cable has a small impact on the signal quality, the information processing effect of the storage device is better. When it is necessary to route, manage the wires and plug and unplug the connection cable, only the bottom plate 112 needs to be disassembled.

[0095] In addition, for the storage device provided by the embodiment of the present invention, the number of 3.5-inch hard disks 200 that can be accommodated under 4U height is more, realizing a high-density storage device. The central component 150 is used as an independent overall structure, locked to the side plate 111 of the housing component 110 by screws and rivets, and capped by the top plate 113 of the housing component 110. The storage device forms a multi-layer fixed structure, improving the structural strength of the storage device, and thus improving the anti-deformation ability of the storage device. While ensuring the convenience of assembly of the storage device, the production cost of the storage device is reduced.

[0096] Refer to Figures 8 to 17 , and the storage device provided by the embodiment of the present invention also has the following characteristics.

[0097] The overall structure of the chassis assembly 100 is rectangular. Along the length direction of the chassis assembly 100, the chassis assembly 100 has a front end and a rear end. An air inlet is provided at the front end of the chassis assembly 100 to allow air flow to enter the chassis assembly 100 through this air inlet. An air outlet is provided at the rear end of the chassis assembly 100 to allow the air flow in the chassis assembly 100 to flow out through this air outlet. That is, the chassis assembly 100 is configured with an air inlet and an air outlet.

[0098] The chassis assembly 100 includes a housing component 110, a slideway component 120, and a central component 150. The central component 150 is located at the rear end of the slideway component 120. The housing component 110 is disposed outside the central component 150 and is detachably connected to the central component 150.

[0099] Among them, the central component 150 includes a central frame 151, a power module 152, a main control module 153, and a fan module 155 disposed on the central frame 151. The main control module 153 is disposed on one side of the central frame 151, the power module 152 is disposed on the other side of the central frame 151, and the fan module 155 is located between the power module 152 and the main control module 153 to draw air, so that the air flow entering the chassis assembly 100 from the air inlet can smoothly flow out from the air outlet.

[0100] The housing component 110 is disposed outside the slideway component and the central component 150. The housing component 110 includes two side plates 111 and a top plate 113 that are oppositely arranged. The top plate 113 is respectively connected to each side plate 111. The side plates 111, the slideway component 120, and the top plate 113 enclose a first air duct 10. The first air duct 10 is respectively communicated with the air inlet and the air outlet. The ventilation area of the first air duct 10 relatively close to the air inlet is larger than the ventilation area of the first air duct 10 relatively close to the air outlet.

[0101] It can be understood that for the storage device provided in the embodiment of the present invention, the first air duct 10 is formed by enclosing the side plate 111, the slideway component 120 and the top plate 113. The first air duct 10 is respectively communicated with the air inlet and the air outlet. The ventilation area of the first air duct 10 relatively close to the air inlet is larger than the ventilation area of the first air duct 10 relatively close to the air outlet. In this way, it is equivalent to having a blocking surface at the position of the first air duct 10 close to the air outlet end, so that the ventilation area at the position of the first air duct 10 close to the air outlet end is reduced. According to the Venturi effect, when the air flow blows through the blocking surface of the first air duct 10, the air pressure is relatively low near the upper port of the leeward side of the blocking surface, thereby generating an adsorption effect and causing the air to flow. That is, it is equivalent to the air flow changing from thick to thin to accelerate the air flow rate, that is, increasing the wind speed, so as to quickly discharge the air flow and avoid accumulation at the rear end of the first air duct 10. When the hard disk 200 is inserted into the slideway component 120, high-pressure air flow can be poured into the hard disk 200 at the rear end of the slideway component 120 through the first air duct 10, increasing the wind speed between the hard disks 200 at the rear end of the slideway component 120, thereby reducing the temperature of the hard disks 200 at the rear end of the slideway component 120 to improve the heat dissipation effect. It effectively solves the problem that due to heat convection, the hot air floats upward and is easy to accumulate above and at the rear end of the array of hard disks 200, resulting in the heat of the array of hard disks 200 being concentrated at the edges and the rear rows, and the heat dissipation effect is poor.

[0102] Since both the power supply module 152 and the main control module 153 are equipped with fans, separating the power supply module 152 and the main control module 153 from each other not only reduces heat accumulation but also avoids mutual influence between the air ducts. At the same time, it can effectively prevent the rear of the array of hard disks 200 from being blocked by the backplane 1531 of the power supply module 152 and the backplane 1531 of the main control module 153, so as to increase the resistance of the second sub-air duct 20 and reduce the effective air volume of the second sub-air duct 20, thereby improving the heat dissipation efficiency of the array of hard disks 200. It is equivalent to that the air ducts provided inside the storage device in the embodiment of the present invention are dedicated to optimizing the air duct resistance and the heat distribution of the array of hard disks 200 to increase the effective air volume of the air duct and solve the heat dissipation bottleneck of the array of hard disks 200.

[0103] In some embodiments of the present invention, the first air duct 10 includes a first sub-air duct (not labeled in the figure) and a second sub-air duct 20. The ventilation path of the first sub-air duct is shorter than that of the second sub-air duct 20. The second sub-air duct 20 is respectively communicated with the air inlet and the air outlet. The air inlet end of the first sub-air duct is communicated with the air inlet, and the air outlet end of the first sub-air duct is communicated with the second sub-air duct 20, so that the air flow of the first sub-air duct converges into the second sub-air duct 20 to increase the air speed at the rear end of the second sub-air duct 20. Equivalently, at the air outlet end of the first sub-air duct, the air flow changes its path and converges from the first sub-air duct into the second sub-air duct 20, thereby increasing the air flow rate of the second sub-air duct 20. According to the Venturi effect, when the air flow changes from thick to thin, the gas flow rate is accelerated, that is, the air speed is increased, so that the air flow is quickly discharged to avoid heat accumulation around the hard disk at the rear end.

[0104] Equivalently, in the embodiments of the present invention, the first air duct 10 is divided into two independent air ducts, namely the first sub-air duct and the second sub-air duct. The first sub-air duct can be formed by the common enclosure of two side plates 111, a top plate 113 and the upper surface of the slide member 120. That is, a baffle can be provided above the slide member 120 to divide the first air duct 10 into two independent air ducts.

[0105] Continue to refer to Figure 1 、 Figure 5 , Figures 9 to 13 In some embodiments of the present invention, a third air duct 30 is formed in the side plate 111 along the length direction. The air inlet end of the third air duct 30 is communicated with the air inlet, and the air outlet end of the third air duct 30 is communicated with at least one of the first air duct 10 and the second sub-air duct 20. In one case, the air outlet end of the third air duct 30 can be communicated with one of the first air duct 10 and the second sub-air duct 20; in another case, the air outlet end of the third air duct 30 can be simultaneously communicated with the first air duct 10 and the second sub-air duct 20.

[0106] Continue to refer to Figures 12 to 14 In some embodiments of the present invention, the side plate 111 includes a plate body and a handle strip 1111. The handle strip 1111 is provided at a position close to the upper side of the plate body. A third air duct 30 is formed between the handle strip 1111 and the plate body. That is, the third air duct 30 is located at the position of the handle strip 1111 in the upper half area of the side plate 111, and the third air duct 30 is formed by the common restriction of the handle strip 1111 and the plate body. The lower half area of the side plate 111 is matched with the cabinet slide rail.

[0107] Since the slide member 120 is fixed to the side plate 111, when the hard disk 200 array is mounted on the slide member 120, it is difficult for the left and right sides of the array hard disk 200 to ventilate, resulting in poor heat dissipation on both sides of the array hard disk 200. Therefore, in the embodiment of the present invention, without adding other components, the original structure of the storage device in the embodiment of the present invention is improved, that is, a third air duct 30 is extended between the handle strip 1111 and the plate body of the side plate 111. In this way, the air flow entering from the air inlet enters the first air duct 10, the second sub-air duct 20, and the third air duct 30 respectively, and then the air flow in the first air duct 10 gradually converges into the second sub-air duct 20 to increase the air flow speed at the rear end of the second sub-air duct 20, thereby improving the heat dissipation effect of the hard disk 200 located at the rear end of the slide member 120. At the same time, in one case, the air flow in the third air duct 30 can enter the first air duct 10 and then converge into the second sub-air duct 20 from the first air duct 10, further increasing the air flow speed at the rear end of the second sub-air duct 20. In another case, the air flow in the third air duct 30 can directly enter the second sub-air duct 20, further increasing the air flow speed at the rear end of the second sub-air duct 20. In still another case, a part of the air flow in the third air duct 30 enters the first air duct 10 and converges into the second sub-air duct 20 from the first air duct 10; another part of the air flow in the third air duct 30 directly enters the second sub-air duct 20. In this way, the air flow speed at the rear end of the second sub-air duct 20 can be increased, and the heat dissipation effect of the hard disk 200 located at the rear end of the slide member 120 can be further improved.

[0108] Continue to refer to Figures 12 to 14 , in some embodiments of the present invention, a ventilation gap is formed between the side plate 111 and the top plate 113, and the ventilation gap communicates the third air duct 30 and the first air duct 10, so that the air flow in the third air duct 30 enters the first air duct 10 and then converges into the second sub-air duct 20 from the first air duct 10, further increasing the air flow speed at the rear end of the second sub-air duct 20.

[0109] Ventilation holes can also be opened on the side wall of the plate body, and the positions of the ventilation holes correspond to the positions of the hard disks 200. The ventilation holes communicate the third air duct 30 and the second sub-air duct 20, and the air flow in the third air duct 30 can directly enter the second sub-air duct 20, further increasing the air flow speed at the rear end of the second sub-air duct 20.

[0110] In some embodiments, a ventilation gap can be formed between the side plate 111 and the top plate 113, and at the same time, ventilation holes are opened on the side wall of the plate body, so that a part of the air flow in the third air duct 30 enters the first air duct 10 and converges into the second sub-air duct 20 from the first air duct 10; and another part of the air flow in the third air duct 30 directly enters the second sub-air duct 20.

[0111] It should be noted that, correspondingly, the handle strip 1111 is in a shell-like structure, with an opening provided at the front end of the handle strip 1111, that is, at the position of the air inlet. The handle strip 1111 is provided with an opening to form an independent air inlet, and the rear end of the handle strip 1111 is closed. The handle strip 1111 is in sealed cooperation with the plate body so that the third air duct 30 forms an independent air duct to prevent the air flow from flowing randomly. In this way, for the hard disk 200 at the outermost front end, the air flow in the third air duct 30 passes over the hard disk 200 and enters the first air duct 10 and then flows backward. For the hard disks 200 at the rear end, the air flow in the third air duct 30 flows into the gaps between the internal hard disks 200, and finally, it flows backward through the second sub-air duct 20.

[0112] Continue to refer to Figures 12 to 14 , in some embodiments of the present invention, the housing component 110 further includes a bottom plate 112. The bottom plate 112 is provided at the bottom of the slideway component 120 and constructs a fourth air duct 40 with the slideway component 120. Both the air inlet end and the air outlet end of the fourth air duct 40 are communicated with the second sub-air duct 20. Here, correspondingly, the above-mentioned slideway component 120 and the hard disk carrier 130 are combined into an integral structure, and the hard disk carrier 130 serves as the bottom wall of the slideway component 120.

[0113] Specifically, the slideway component 120 includes a slideway main body and a hard disk carrier 130. The hard disk carrier 130 is detachably connected to the bottom of the slideway component 120. A fourth air duct 40 is constructed between the hard disk carrier 130 and the bottom plate 112. The hard disk carrier 130 is provided with a plurality of air passing holes 135 distributed in an array. The air passing holes 135 communicate the fourth air duct 40 and the second sub-air duct 20. Both the air inlet end and the air outlet end of the fourth air duct 40 are communicated with the second sub-air duct 20. A part of the air flow entering from the position of the second sub-air duct 20 close to the air inlet enters the front end of the fourth air duct 40 through the air passing holes 135, and then enters the second sub-air duct 20 through the air passing holes 135 at the rear end of the fourth air duct 40 and is discharged.

[0114] Continue to refer to Figure 7 and Figure 8 , in some embodiments of the present invention, the air passing area of the air passing holes 135 near the front end of the hard disk carrier 130 is smaller than the cross-sectional area of the air passing holes 135 near the rear end of the hard disk carrier 130. Correspondingly, the sizes of the air passing holes 135 on the hard disk carrier 130 are inconsistent. By adjusting the sizes of the air passing holes 135, the area of the air passing holes 135 near the front end of the chassis assembly 100, that is, far from the fan module 155, is made smaller, and the area of the air passing holes 135 near the rear end of the chassis assembly 100, that is, close to the fan module 155, is made larger.

[0115] For example, the air passing holes 135 in the first area A at the front end of the hard disk carrier 130 correspond to the projection areas of the first air duct 10 and the second sub-air duct 20. The air passing holes 135 in the second area B in the middle section of the hard disk carrier 130 correspond to the projection area of the second sub-air duct 20. The air passing holes 135 in the third area C at the rear end of the hard disk carrier 130 correspond to the hard disk 200 in the second installation cavity 1514. By adjusting the sizes of the air passing holes 135 at the front and rear ends of the hard disk carrier 130, the local air pressure in the second sub-air duct 20 is changed, so that the air flow direction of the second sub-air duct 20 at the front end enters the fourth air duct 40 from top to bottom, and the air flow direction of the fourth air duct 40 at the rear end enters the second sub-air duct 20 from bottom to top, driving more cold air into the second sub-air duct 20 at the rear end to reduce the temperature of the array hard disk 200 at the rear end.

[0116] In this way, since the array hard disk 200 is installed in the second sub-air duct 20, the air flow pressure loss is large, while there is no obstruction in the fourth air duct 40, and the air flow pressure loss is small. A part of the air flow entering the second sub-air duct 20 from the air inlet enters the fourth air duct 40 through the air passing holes 135. Since the area of the air passing holes 135 near the air inlet is small and the area of the air passing holes 135 near the air outlet is large, it is equivalent that the area of the air inlet of the fourth air duct 40 is smaller than the area of the air outlet of the fourth air duct 40. For details, refer to Figure 19 , judging from the air flow speeds at the air inlet and the air outlet, a larger air outlet can actually achieve a higher ventilation speed for a smaller air inlet, which can further improve the heat dissipation effect of the hard disk 200 located at the rear end of the slide component 120.

[0117] In addition, the air flow speed of the fourth air duct 40 can be appropriately increased and the air pressure of the fourth air duct 40 can be reduced, so that the air pressure near the front end of the second sub-air duct 20 is higher than that of the fourth air duct 40, and the air pressure near the rear end of the second sub-air duct 20 is lower than that of the fourth air duct 40. The air flow flows from the positive pressure to the negative pressure, so that the air flow near the front end of the second sub-air duct 20 flows into the fourth air duct 40 from top to bottom, and the air flow near the rear end of the fourth air duct 40 flows into the second sub-air duct 20 from bottom to top, cooling the array hard disk 200 near the rear end in the second sub-air duct 20, that is, cooling the array hard disk 200 located at the rear end of the slide component 120.

[0118] Since a part of the air flow entering the second sub-air duct 20 from the air inlet enters the fourth air duct 40 through the air passing holes 135, this part of the air flow entering the fourth air duct 40 is equivalent to a cold air flow. The cold air flow passes through the fourth air duct 40 and enters the rear end of the second sub-air duct 20, cooling the array hard disk 200 near the rear end in the second sub-air duct 20, that is, cooling the array hard disk 200 located at the rear end of the slide component 120. It can reduce the influence of the heat generated by the array hard disk 200 in the second sub-air duct 20 on the array hard disk 200 near the rear end in the second sub-air duct 20, so that the heat dissipation effect of the hard disk 200 located at the rear end of the slide component 120 is better.

[0119] In addition, ventilation holes 135 are also provided in the area of the 9 columns of hard disks 200 on the hard disk carrier 130 corresponding to the second installation cavity 1514 described above, so as to increase the air intake area of the fan module.

[0120] Continue to refer to Figure 15 and Figure 16 In some embodiments of the present invention, the main control module 153 includes a main control housing, and a main control fan, a main control component and a daughter card component provided in the main control housing; the main control housing is provided with a first placement cavity (equivalent to the first sub-slot 1512-1 described above) and a second placement cavity (equivalent to the second sub-slot 1512-2) at intervals. The main control fan and the daughter card component are provided in the first placement cavity, and the main control fan is located below the daughter card component. The air flow behavior of the main control fan is from bottom to top, and the main control component is provided in the second placement cavity;

[0121] Continue to refer to Figure 15 and Figure 16 The first placement cavity is configured with a first heat dissipation channel 80, and a first air intake channel 50 is configured between the main control housing and the hard disk carrier 130 of the slide component 120. The first air intake channel 50 is communicated with the first heat dissipation channel 80 and the fourth air duct 40; the second placement cavity is configured with a second heat dissipation channel 90 and an air outlet communicated with the second heat dissipation channel 90, and the second heat dissipation channel 90 is communicated with the first heat dissipation channel. The air flow in the fourth air duct 40 can enter the main control module 153 through the first air intake channel 50 to dissipate heat and cool it.

[0122] Continue to refer to Figure 16 A first sub-air intake channel 51 is configured between the back plate 1531 of the main control housing and the hard disk carrier 130 of the slide component 120, and a second sub-air intake channel 52 is configured between the side plate 111 of the main control housing and the hard disk carrier 130 of the slide component 120; both the first sub-air intake channel 51 and the second sub-air intake channel 52 are communicated with the first heat dissipation channel 80, and both the first sub-air intake channel 51 and the second sub-air intake channel 52 are also communicated with the fourth air duct 40. That is, specifically refer to Figure 1 and Figure 7 By cutting the area on the hard disk carrier 130 (PCB board) corresponding to the daughter card part of the main control module 153, the first sub-air intake channel 51 and the second sub-air intake channel 52 are formed to increase the air intake area of the main control module 153.

[0123] This is equivalent to isolating the chassis assembly 100 into a multi-layer air duct using the hard disk carrier 130 (PCB board) and foam and other structures, including at least the second sub-air duct 20 and the fourth air duct 40. The second sub-air duct 20 takes away the heat of the array hard disk 200, and the fourth air duct 40 can enter the main control module 153 through the first sub-air inlet channel 51 and the second sub-air inlet channel. In addition, the back plate 1531 of the main control module 153 and the hard disk carrier 130 are used to isolate the second sub-air duct 20 from the various heat dissipation channels of the main control module 153. Foam can be added to the gaps between the back plate 1531 of the main control module 153 and the hard disk carrier 130 for sealing and isolation to avoid the second sub-air duct 20 and the various heat dissipation channels of the main control module 153 from affecting each other.

[0124] Among them, the backplane 1531 can be a special-shaped structure, and the backplane 1531 is set according to the structure of the main control module 153 to completely block the area where the main control module 153 is located toward one end of the array hard disk 200, thereby preventing the air outlet of the fan of the main control module 153 from flowing back to the second sub-air duct 20.

[0125] In addition, a main control board, a heat sink and a memory stick are provided inside the main control component. The heat sink is provided on the main control board. A wind shield is provided on the main control board. The heat sink is wrapped in the wind shield. An air outlet of the main control component is formed at one end of the wind shield. The memory stick is located outside the wind shield.

[0126] The storage device provided by an embodiment of the present invention has an air duct arranged inside, and the airflow direction of the air is as follows: the cold air of the fourth air duct 40 enters the first heat dissipation channel 80 from the first sub-air inlet channel 51 and the second sub-air inlet channel 52, passes through the main control fan, the sub-card component, the main control board and the wind shield in sequence, and is discharged from the exhaust port of the main control component.

[0127] See also Figure 17 In some embodiments of the present invention, a second air inlet channel 60 is constructed on the bottom wall of the power module 152, and a third air inlet channel 70 is constructed between the side wall of the power module 152 and the back panel 1531 of the power module 152, and both the second air inlet channel 60 and the third air inlet channel 70 are connected to the fourth air duct 40.

[0128] In some embodiments, the power module 152 includes a plurality of power components stacked together, the third air inlet channel 70 extends along the height of the power module 152, and the airflow of the third air inlet channel 70 can be diverted to each power component. The power module 152 has its own temperature sensor and fan for speed regulation. When the temperature of the power module 152 rises, the fan of the power module 152 will autonomously distribute the air volume to each power component.

[0129] The second air inlet channel 60 and the third air inlet channel 70 of the power supply module 152 are similar to the first air inlet channel 50 of the above-mentioned main control module 153. By cutting the area corresponding to the power supply module 152 on the hard disk carrier 130 (PCB board), the second air inlet channel 60 is formed to increase the air inlet area of the power supply module 152. For the power supply components at the bottom layer, the air flow entering from the fourth air duct 40 can directly enter from the front of the power supply components, that is, enter through the second air inlet channel 60. For multiple layers of power supply components, for the upper-layer power supply components, due to the obstruction of the power supply connector 170, they cannot smoothly enter the air from the front. Then, an independent third air inlet channel 70 is framed between the side plate 111 of the power supply module 152 and the back plate 1531 of the power supply module 152. The third air inlet channel 70 extends along the height of the power supply module 152, which is equivalent to the main air inlet channel. The air flow in the third air inlet channel 70 is split to each layer of power supply components, similar to a "tree branch-shaped" air flow channel, which is equivalent to the upper-layer power supply components entering the air from the side.

[0130] Since the hot air accumulated by the array hard disks 200 cannot meet the heat dissipation requirements of the high-power main control module 153 and the power supply module 152, and the back plate 1531 of the main control module 153, the back plate 1531 of the power supply module 152, and the connector 170 at the power supply end will block the air inlets of the main control module 153 and the power supply module 152, resulting in difficult air inlet for the main control module 153 and the power supply module 152. The storage device provided by the embodiment of the present invention has an air duct internally arranged, which can not only reduce the resistance of the air inlets of the main control module 153 and the power supply module 152, but also, the cold air from the fourth air duct 40 enters the main control module 153 and the power supply module 152, which can reduce the temperature at the main control module 153 and the power supply module 152; and, isolating the heat dissipation channels of the main control module 153 and the power supply module 152 from the heat dissipation channel of the array hard disks 200 can solve the problem of poor heat dissipation effect of the main control module 153 and the power supply module 152.

[0131] In some embodiments of the present invention, the slide member 120 includes a plurality of slide brackets 122 arranged at intervals and a connecting member 123. The connecting member 123 is located between two adjacent slide brackets 122 and is detachably connected to the two adjacent slide brackets 122 respectively, so as to form an installation slot for accommodating the hard disk 200 between the two adjacent slide brackets 122.

[0132] Each slide bracket 122 is provided with a ventilation opening 1224, and the position of the ventilation opening 1224 corresponds to the installation position of the hard disk 200, so as to form the above-mentioned second sub-air duct 20 between the slide brackets 122 and among the array hard disks 200. When the hard disk 200 is arranged in the installation slot, the hard disk 200 blocks part of the ventilation opening 1224. A flange portion 1225 is provided on the edge of the ventilation opening 1224 and extends outwards; a slideway is formed between the flange portions 1225 of the ventilation openings 1224 of two adjacent slide brackets 122, and the hard disk 200 is inserted into the slideway, so as to form an air flow gap between the hard disk 200 and the slideway body 1221 of the slide bracket 122.

[0133] Continue to refer to Figure 12 , there is a gap between the slide bracket 122 at the front end of the chassis assembly 100 and the top plate 113 to form the first air duct 10, and the slide bracket 122 at the rear end of the chassis assembly 100 abuts against the top plate 113 to change the path of the first air duct 10. In this way, it is equivalent to that the height of the slide bracket 122 at the front end is reduced, and the height of the slide bracket 122 at the rear end is increased to abut against the top plate 113, so that the high-pressure air flow can be poured into the second sub-air duct 20 at the rear end through the first air duct 10, increasing the air speed among the array hard disks 200 at the rear end to reduce the temperature of the array hard disks 200 at the rear end. Refer to Figure 18 , this solution aims to improve the heat dissipation of the array hard disks 200 at the rear end, so that the air speed entering the second sub-air duct 20 from the front end of the first air duct 10 is less than 3 m / s, and the air speed entering the second sub-air duct 20 from the rear end of the first air duct 10 reaches about 5 m / s.

[0134] Refer to Figures 20 to 23 , it can be understood that for the storage device provided by the embodiment of the present invention, the air duct arranged inside it can solve the heat dissipation problem of the array hard disks 200 at the rear end and effectively solve the heat dissipation problems of the main control module 153 and the power module 152 without introducing new heat dissipation devices (such as radiators, fans, etc.) in the compact internal space. For details, refer to Figure 22 , improving the temperature of the hard disk 200 on the outer side of the front and rear ends is 5 °C higher than the temperature of the hard disk 200 on the inner side of the same row. For details, refer to Figure 23 , after improvement, the temperature of the hard disk 200 on the outer side of the rear end is about 3 °C lower than the temperature of the hard disk 200 on the inner side of the same row, and the temperature rise optimization amplitude of the hottest hard disk 200 exceeds 34%, and the heat dissipation effect is obvious.

[0135] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
