[0019] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0020] The network storage device provided by the embodiments of the present application is shown in FIG. 1 to FIG. 4, which comprises a shell 1, a first hard disk 2 and a second heat dissipation assembly 3. The shell 1 is provided with a hard disk assembly space 11. The first hard disk 2 and the second heat dissipation assembly 3 are assembled in the hard disk assembly space 11. The second heat dissipation assembly 3 comprises a second turbine fan 31. The shell 1 is provided with a first air inlet 121 corresponding to the air inlet of the second turbine fan 31 at the bottom, and is provided with a first air outlet 122. The air outlet of the second turbine fan 31 blows towards the first air outlet 122. The hard disk assembly space 11 is provided with a wind guide inclined surface 111 corresponding to the position of the first air outlet 122, which guides the air outlet of the first air outlet 122 to the outside of the bottom of the shell 1.

[0021] The network storage device of the present application is provided with the hard disk assembly space 11 at the bottom of the shell 1, which is used as the assembly space dedicated to the first hard disk 2, and is provided with the second heat dissipation assembly 3 corresponding thereto. The heat can be blown away by the second turbine fan 31 corresponding thereto, so that the first hard disk 2 can be more effectively cooled in a small space. The hard disk assembly space 11 is provided with the wind guide inclined surface 111 corresponding to the position of the first air outlet 122, which guides the air outlet of the first air outlet 122 to the outside of the bottom of the shell 1. The air outlet of the first air outlet 122 flows to the outside of the bottom under the guidance of the wind guide inclined surface 111, so that the hot air blown by the first air outlet 122 is not easily sucked back into the hard disk assembly space 11 by the first air inlet 121 at the bottom, thereby ensuring the heat dissipation effect. Since the air outlet flows to the outside of the bottom under the guidance of the wind guide inclined surface 111, the external air can be quickly guided to flow to the first air inlet 121 at the bottom, thereby accelerating the air inlet and improving the heat dissipation effect. The network storage device has good heat dissipation effect.

[0022] Specifically, the hard disk assembly space 11 is arranged at the bottom of the shell 1. The first hard disk 2 can be a solid state disk (SSD). A plurality of first hard disks 2 can be arranged side by side in the hard disk assembly space 11, for example, four first hard disks 2 are arranged side by side.

[0023] Specifically, on the bottom of the shell 1, a airflow blocking ridge is arranged between the first air inlet 121 and the first air outlet 122, and the airflow blocking ridge is used to block the air flow between the first air inlet 121 and the first air outlet 122. The scheme further provides the airflow blocking ridge between the first air inlet 121 and the first air outlet 122 to block, which can reduce the possibility that the hot air of the first air outlet 122 is sucked back to the first air inlet 121. The airflow blocking ridge is a blocking edge with a certain height formed on the bottom surface of the shell 1. Specifically, when the first air inlet 121 and the first air outlet 122 are arranged on the cover plate 12 described below, the airflow blocking ridge is also arranged on the cover plate 12.

[0024] The network storage device further comprises a main control circuit board installed in the shell 1. Further in combination with FIG. 6, the main control circuit board is provided with a plug-in port 4. The hard disk assembly space 11 is provided with a first opening 112 penetrating the inside of the shell 1, and the plug-in port 4 is plugged into the first opening 112 from the inside of the shell 1, and the connecting end of the first hard disk 2 is plugged into the plug-in port 4. The plug-in port 423 can be, for example, an M.2 interface. The first hard disk 2 is plugged into the plug-in port 4 to realize its installation and use. The other end of the first hard disk 2 can be fixed by a screw clamp. When there are multiple first hard disks 2, the plug-in port 423 is also provided in a corresponding number. Further, the bottom of the shell 1 is formed with a spacing space 5, and the first air inlet 121 and the first air outlet 122 are located at the spacing space 5, so that the first air inlet 121 and the first air outlet 122 have a spacing with the placement surface of the network storage device. The spacing space 5 facilitates the circulation of air at the bottom of the network storage device after being placed on the placement surface, ensuring that air can enter the hard disk assembly space 11 from the first air inlet 121 and be blown out from the first air outlet 122. Specifically, a foot pad 13 can be arranged on the bottom of the shell 1 to form the spacing space 5, or the spacing space 5 can be formed by a bottom recess. When the bottom is recessed, the recessed edge can be provided with a gap for airflow circulation corresponding to the first air inlet 121 and the first air outlet 122.

[0025] Specifically, the second heat dissipation assembly 3 further comprises a second heat dissipation piece 32, which is arranged corresponding to the first hard disk 2, and the air outlet of the second turbine fan 31 blows through the second heat dissipation piece 32. The second heat dissipation piece 32 can quickly take away heat.

[0026] The air guide slope 111 is an arc slope arranged at the side of the hard disk assembly space 11. The arc slope is conducive to smoothly and effectively guiding the air flow blown by the second turbine fan 31 to the first air outlet 122, reducing air resistance, reducing noise, and improving air guide efficiency. The upper edge of the arc slope is arranged close to the first air outlet 122, and the lower edge is arranged close to the second heat dissipation member 32. In the present scheme, the two side edges of the arc slope are respectively close to the first air outlet 122 and the second heat dissipation member 32. The air flow passing through the second heat dissipation member 32 can be directly guided to the first air outlet 122 by the arc slope, reducing the flow of air to the surroundings.

[0027] The second heat dissipation member 32 includes a mounting plate 321 and a heat dissipation fin 322 connected to each other. The second turbine fan 31 is mounted on the mounting plate 321, and the first air outlet 122 of the second turbine fan 31 is arranged corresponding to the heat dissipation fin 322.

The air outlet of the second turbine fan 31 is arranged corresponding to the heat dissipation fin 322, and the heat dissipation fin 322 is arranged corresponding to the first air outlet 122, so that the heat of the heat dissipation fin 322 can be quickly taken away from the first air outlet 122. Specifically, the heat dissipation fin 322 is close to the air guide slope 111, and the mounting plate 321 is away from the air guide slope 111. The heat dissipation fin 322, as the main heat dissipation part of the second heat dissipation member 32, is arranged close to the air guide slope 111, so that the heat of the heat dissipation fin 322 can be quickly taken away through the air guide slope 111 and the first air outlet 122. Two second turbine fans 31 are arranged, and both of them are mounted on the mounting plate 321. The first air inlet 121 is provided with two corresponding second turbine fans 31, so as to improve the heat dissipation effect.

[0028] Further, the first hard disk 2 is attached with a heat conduction member 8, and the second heat dissipation member 32 is attached to the heat conduction member 8. The heat conduction member 8 can improve the heat transfer speed of the first hard disk 2, and the heat dissipation effect is better. The heat conduction member 8 can be a heat conduction film.

[0029] Further, as shown in FIG. 2, FIG. 3 and FIG. 5, the shell 1 comprises a cover plate 12 which is detachably covered on the hard disk assembling space 11; the first air inlet 121 and the first air outlet 122 are arranged on the cover plate 12. The detachable cover plate 12 makes the hard disk assembling space 11 be able to be maintained, disassembled and assembled at any time. The cover plate 12 can be fixedly installed on the hard disk assembling space 11 by screws, so as to realize the detachable installation. Specifically, the second heat dissipation member 32 is installed on the inner side of the cover plate 12, and the second turbine fan 31 and the second heat dissipation member 32 are installed on the cover plate 12 to form a modularization. When the cover plate 12 is opened, the second turbine fan 31 and the second heat dissipation member 32 can be taken out at the same time, the first hard disk 2 is exposed, and the first hard disk 2 is convenient to disassemble and maintain. The connection pin 6 can be arranged on the main control circuit board, the connection pin 6 is arranged in the through hole in the hard disk assembling space 11, the connection circuit board 7 connected with the second turbine fan 31 through the socket and the plug is installed on the inner side of the cover plate 12, and the connection terminal 71 is arranged on the connection circuit board 7 corresponding to the connection pin 6. When the cover plate 12 is covered on the hard disk assembling space 11, the connection pin 6 is connected with the connection terminal 71, so as to realize the power supply and control of the second turbine fan 31.

[0030] As shown in FIG. 1 to FIG. 6, the second heat dissipation assembly 3 is installed on the inner side of the cover plate 12, and when the cover plate 12 is covered on the hard disk assembling space 11, the second heat dissipation assembly 3 is assembled in the hard disk assembling space 11, and the second heat dissipation assembly 3 corresponds to the first hard disk 2.

Thus, when the first hard disk 2 needs to be disassembled, the cover plate 12 is disassembled, and the second heat dissipation assembly 3 can also be disassembled at the same time, and the existence of the second heat dissipation assembly 3 does not affect the disassembly of the first hard disk 2. After the cover plate 12 is assembled, the second heat dissipation assembly 3 can effectively dissipate heat for the first hard disk 2 in the independent hard disk assembling space 11. The hard disk assembling space 11 provides the assembling space for the first hard disk 2 and also provides the assembling space for the second heat dissipation assembly 3, so as to fully utilize the space. That is, the network storage device of the present application considers the disassembly requirement of the first hard disk 2, has a better heat dissipation effect, fully utilizes the space and the modularization, and is beneficial to miniaturization.

[0032] Specifically, the cover plate 12 is provided with a first air inlet 121 corresponding to the air inlet of the second turbine fan 31 and a first air outlet 122 corresponding to the second heat dissipation member 32. The air outlet of the second turbine fan 31 blows through the second heat dissipation member 32. Under the driving of the second turbine fan 31, the external air enters the hard disk assembly space 11 from the first air inlet 121 and is blown out from the first air outlet 122, thereby taking away the heat of the first hard disk 2. The provision of the second heat dissipation member 32 facilitates the rapid heat dissipation of the first hard disk 2, and the air blown by the second turbine fan 31 through the second heat dissipation member 32 can quickly take away the heat thereon.

[0033] The second heat dissipation member 32 is installed on the inner side of the cover plate 12. The second heat dissipation member 32 serves not only as a heat dissipation component but also provides a mounting position for the second turbine fan 31. Further, a dust screen is provided between the air inlet of the second turbine fan 31 and the first air inlet 121, which can filter the dust in the air and reduce the dust entering the hard disk assembly space 11.

[0034] On the inner side of the cover plate 12, the side of the heat dissipation fin 322 away from the mounting plate 321 corresponds to the first air outlet 122. After the airflow passes through the heat dissipation fin 322, it can be directly blown out from the first air outlet 122, improving the heat dissipation efficiency and reducing the dissipation of hot airflow. The first air outlet 122 is provided with wind baffles 123 on both sides, which can block the airflow from flowing to both sides of the first air outlet 122 and guide the airflow to be concentratedly blown out from the first air outlet 122, improving the heat dissipation effect.

[0035] The main control circuit board is provided with a connecting pin 6, which is inserted into a through hole in the hard disk assembly space 11. The inner side of the cover plate 12 is provided with a connecting circuit board 7 connected to the second turbine fan 31 through a socket and a plug, and the connecting circuit board 7 is provided with a connecting terminal 71 corresponding to the connecting pin 6. When the cover plate 12 is covered on the hard disk assembly space 11, the connecting pin 6 is connected to the connecting terminal 71. Through the cooperation of the connecting terminal 71 and the connecting pin 6, the second heat dissipation assembly 3 can be detachably arranged in the hard disk assembly space 11, and the second turbine fan 31 can be powered and controlled at the same time. The connecting circuit board 7 and the second heat dissipation member 32 can be installed on the inner side of the cover plate 12 by screws.

[0036] Further, the plug-in port 4 can be an M. interface, for example. The first hard disk 2 is plugged into the plug-in port 4 to realize its installation and use. The other end of the first hard disk 2 can be fixed by screws. When there are multiple first hard disks 2, the plug-in port 4 is also provided with a corresponding number.

The first hard disk 2 and the second heat dissipation assembly 3 are assembled in the hard disk assembly space 11, and the second heat dissipation assembly 3 is arranged correspondingly to the first hard disk 2.

[0038] The applicant finds that the current network storage device integrates a set of ventilation and heat dissipation system, and the heat dissipation efficiency of the network storage device is low and the heat dissipation effect is not good. In view of this, the network storage device of the present application divides the housing 1 into a main control assembly space 14 and a hard disk assembly space 11, installs the main control circuit board 9 with a large heat generating first chip 91 in the main control assembly space 14, and assembles the first hard disk 2 with a large heat generating in the hard disk assembly space 11, and sets the first heat dissipation assembly 10 and the second heat dissipation assembly 3 in the main control assembly space 14 and the hard disk assembly space 11 respectively to dissipate heat respectively, independently and without interference, which also reduces the size of the heat dissipation space of the first heat dissipation assembly 10 and the second heat dissipation assembly 3 respectively, and improves the heat dissipation efficiency and the heat dissipation effect.

[0039] Specifically, the first chip 91 is a central processing unit (CPU) of the network storage device, and its specific model can be selected according to actual needs, which will not be described here.

[0040] Specifically, the main control assembly space 14 includes a memory assembly space 15, which is arranged side by side with the hard disk assembly space 11. The main control circuit board 9 is provided with a memory bank 92, which is located in the memory assembly space 15. The present scheme sets the memory assembly space 15 on the side of the hard disk assembly space 11, which sets a relatively independent space for the memory bank 92, which is also relatively large in heat generation, in the main control assembly space 14, which is conducive to the heat dissipation of the memory bank 92 and the corresponding heat dissipation device, such as the first heat dissipation component 30 described below.

The air outlet of the first turbine fan 101 is connected with the first air port 16. The air inlet of the second turbine fan 31 can quickly take away the heat generated by the first chip 91. At the same time, since the air outlet of the second turbine fan 31 is connected with the first air port 16, the second air port 17 and the remaining first air port 16 serve as air inlets, the air inlet is sufficient, and all the air inlets eventually converge at the first chip 91 and are blown out by the first turbine fan 101, so that the first chip 91 has good heat dissipation effect. At the same time, the second air port 17 is provided corresponding to the memory bar 92, so that the heat generated by the memory bar 92 can be quickly taken away when air is inhaled.

The shielding cover 40 can protect the memory bar 92. The heat of the memory bar 92 can be quickly transferred to the first heat dissipation piece 30 through the shielding cover 40 and the heat-conducting medium, so as to be quickly taken away by the airflow of the second air port 17, thereby improving the heat dissipation efficiency.
