Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a hard disk enclosure. Background Technology

[0002] Solid-state drives (SSDs) are hard drives made using solid-state electronic storage chip arrays, consisting of a control unit and storage units. A hard drive enclosure provides physical protection for the drive while also providing a convenient connection method for portability, enabling it to function as an external hard drive.

[0003] In related technologies, hard drive enclosures typically use cooling fans for heat dissipation. These fans are positioned on one side of the hard drive, and the enclosure has ventilation holes on two opposite walls near the fan to expel heat from the interior to the external environment. However, this method concentrates the airflow near the fan, resulting in better heat dissipation in that area and poorer heat dissipation in areas further away, leading to ineffective overall cooling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0031] Please refer to Figures 1 to 7 This utility model proposes a hard disk enclosure 100, which includes: a enclosure body 10, the enclosure body 10 having a receiving cavity 11 and an air inlet 141 and an air outlet 131 communicating with the receiving cavity 11; a cooling fan 20, the cooling fan 20 being disposed in the receiving cavity 11, the cooling fan 20 having an inlet (not shown in the figure) and an outlet 21, the inlet communicating with the air inlet 141, the outlet 21 communicating with the air outlet 131, and a heat dissipation area 12 being formed between the inlet and the air inlet 141; and a hard disk assembly 30, the hard disk assembly 30 being disposed in the heat dissipation area 12, and being arranged at intervals with the cooling fan 20 along the arrangement direction of the air inlet 141 and the air outlet 131.

[0032] Specifically, the hard drive enclosure 100 includes a housing 10, a cooling fan 20, and a hard drive assembly 30. The housing 10 is used to install internal components, the cooling fan 20 is used to conduct heat from inside the housing 10 to the external environment through forced convection, and the hard drive assembly 30 is used for storage.

[0033] A heat dissipation zone 12 is formed between the inlet of the cooling fan 20 and the air inlet 141. The hard drive assembly 30 is installed in the heat dissipation zone 12. The inlet of the cooling fan 20 is connected to the air inlet 141. After the air enters from the air inlet 141, it ensures that the air directly enters the heat dissipation zone 12. Guided by the cooling fan 20, the air flows evenly over the surface of the hard drive assembly 30, ensuring that the hard drive assembly 30 is effectively cooled. The airflow can evenly cover the hard drive assembly 30, ensuring that all parts of the hard drive assembly 30 are effectively cooled. After passing through the cooling fan 20, the airflow is discharged from the exhaust port 131. The path is clear, and the airflow can fully remove heat when passing over the hard drive assembly 30, ensuring that the heat dissipation effect is maximized.

[0034] Placing the hard drive assembly 30 within the heat dissipation area 12 ensures that the airflow generated by the cooling fan 20 directly acts on the hard drive assembly 30, thereby improving heat dissipation efficiency.

[0035] Meanwhile, the hard drive assembly 30 and the cooling fan 20 are arranged at intervals along the air inlet 141 and the air outlet 131. Air enters from the air inlet 141, passes through the hard drive assembly 30, and is then exhausted from the air outlet 131 by the cooling fan 20, ensuring the directionality and continuity of airflow. Furthermore, the rational arrangement of the cooling fan 20 and the hard drive assembly 30 enables efficient heat dissipation within a limited space, facilitating the miniaturization of the hard drive enclosure 100.

[0036] This utility model's technical solution involves installing the hard disk assembly 30 in the heat dissipation area 12, with the inlet of the cooling fan 20 connected to the air inlet 141. Guided by the cooling fan 20, an airflow circulation is formed between the air inlet 141 and the exhaust 131. After the airflow enters from the air inlet 141, the air can directly enter the heat dissipation area 12 and flow evenly across the surface of the hard disk assembly 30, ensuring that all parts of the hard disk assembly 30 can be effectively cooled, significantly improving the heat dissipation effect, and protecting the hard disk assembly 30 from overheating damage.

[0037] In an embodiment of this utility model, the hard drive enclosure 100 further includes a heat sink 40, which is connected to the side of the hard drive assembly 30 facing the cooling fan 20.

[0038] In detail, by setting up the heat sink 40, the heat sink 40 can quickly conduct the heat generated by the hard drive assembly 30 to the surface of the heat sink 40. The heat sink 40 increases the heat dissipation surface area, allowing more heat to be dissipated through air convection, thereby improving heat dissipation efficiency.

[0039] The heatsink 40 is connected to the side of the hard drive assembly 30 facing the cooling fan 20, ensuring that the airflow generated by the cooling fan 20 directly acts on the heatsink 40, further improving the cooling effect. The heatsink 40 and the cooling fan 20 work together to form a multi-layer heat dissipation system, maintaining good heat dissipation performance.

[0040] The shape of the heatsink 40 can be set according to the shape of the hard drive assembly 30; it can be set to be a long strip or a block.

[0041] In addition, in one embodiment, the heat dissipation heat sink 40 is thickened to 2mm-4mm, resulting in a larger heat dissipation area, better heat dissipation effect, and better heat management.

[0042] In an embodiment of this utility model, the housing 10 includes an upper shell 13 and a lower shell 14. The upper shell 13 and the lower shell 14 enclose the accommodating cavity 11. The lower shell 14 is provided with an air inlet 141 and forms an installation area 142. The hard disk assembly 30 is disposed in the installation area 142. The upper shell 13 is provided with an exhaust vent 131. The cooling fan 20 is installed on the upper shell 13. The inlet is arranged opposite to the hard disk assembly 30. The air inlet 141, the installation area 142 and the inlet cooperate to form the heat dissipation area 12.

[0043] It is worth noting that the enclosure 10 is configured with an upper shell 13 and a lower shell 14. The separate design of the upper shell 13 and the lower shell 14 makes the installation and removal of the hard drive assembly 30 and the cooling fan 20 more convenient and quick.

[0044] The lower shell 14 has an air inlet 141, and the hard drive assembly 30 is mounted on the lower shell 14. The upper shell 13 has an exhaust vent 131, and the cooling fan 20 is mounted on the upper shell 13. By mounting the cooling fan 20 on the upper shell 13, the heat generated by the hard drive can be concentrated and the hot air can be exhausted from the exhaust vent 131, reducing heat accumulation inside the hard drive enclosure 100. The relative arrangement of the air inlet 141 of the lower shell 14 and the hard drive assembly 30 ensures the correct airflow path when installing the hard drive assembly 30, improving heat dissipation efficiency. The relative arrangement of the air inlet and the hard drive assembly 30 can guide air to flow directly over the surface of the hard drive, improving heat dissipation efficiency. Good heat dissipation can ensure that the hard drive can maintain stable operation under high load, improving overall performance.

[0045] The hard drive assembly 30 and the cooling fan 20 are arranged at intervals along the connection direction between the upper shell 13 and the lower shell 14, such as... Figure 4 The hard drive assembly 30 and the cooling fan 20 are stacked. This stacking arrangement avoids unnecessary detours and short circuits in the airflow during entry and exit. When cool air passes through the hard drive assembly 30, it can evenly cover all parts of the hard drive assembly 30, directly carrying away the heat generated by the hard drive assembly 30 and ensuring maximum heat dissipation. This modular design allows the hard drive assembly 30 and the cooling fan 20 to be installed separately, which not only simplifies the maintenance process but also improves the user experience and maintainability of the equipment.

[0046] By arranging the hard drive assembly 30 and the cooling fan 20 at intervals along the connection direction between the upper shell 13 and the lower shell 14, the positions of each component can be rationally arranged within a limited space, achieving a compact design. Through the cooperation of the air inlet, the mounting area 142, and the air inlet, an effective heat dissipation area 12 can be formed, ensuring that the heat generated by the hard drive during operation can be dissipated in a timely manner.

[0047] In one embodiment, such as Figure 1The enclosure 10 is rectangular with rounded corners on all four sides for easy integration with other devices. The rounded corners reduce the safety hazards of sharp edges and prevent scratches to users or other objects. Furthermore, the rounded corners and size of the enclosure allow it to be seamlessly placed alongside other devices (such as some Apple hard drive enclosures), minimizing gaps between devices and creating a cleaner, more organized desktop.

[0048] In an embodiment of this utility model, the lower shell 14 includes a bottom surface, the air inlet 141 is arranged circumferentially around the bottom surface of the lower shell 14, and the hard disk assembly 30 is located inside the horizontal projection surface of the air inlet 141.

[0049] Specifically, such as Figure 4 and Figure 5 The air inlet 141 surrounds the bottom surface of the lower shell 14, allowing the hard disk assembly 30 to be located inside the horizontal projection surface of the air inlet 141. This ensures that air enters evenly from all sides of the hard disk assembly 30, and the airflow can effectively cover the entire surface of the hard disk assembly 30, which helps to effectively cool all parts of the surface of the hard disk assembly 30.

[0050] In one embodiment, the air inlet 141 is a continuous circular air outlet; in another embodiment, such as Figure 2 and Figure 6 There are multiple air vents, which are evenly spaced to form a ring of air inlets 141.

[0051] The air inlet 141 is arranged circumferentially around the bottom surface, forming an effective airflow. Together with the cooling fan 20, it creates a stable airflow circulation around the hard drive assembly 30, improving heat dissipation efficiency. The surrounding air inlet 141 design reduces hot spots on the hard drive assembly 30, allowing heat to be carried away from all directions. Simultaneously, it provides a larger intake area, allowing more cool air to be introduced, increasing the total airflow and ensuring more cool air passes through the hard drive assembly 30, thus improving heat dissipation efficiency.

[0052] Furthermore, in this embodiment, such as Figure 2 and Figure 7The bottom surface of the lower shell 14 has a conical step 143 protruding outwards, and multiple air inlets 141 are arranged circumferentially around the side of the conical step 143. Positioning the air inlets 141 on the side wall of the conical step 143 increases the distance between the lower shell 14 and the tabletop, effectively preventing the bottom surface of the hard drive enclosure 100 from being blocked by the tabletop or other objects when placed, ensuring that the air inlets 141 remain unobstructed. It also reduces airflow resistance, allowing cool air to enter the enclosure 10 more smoothly from the air inlets 141. The sloping side wall of the conical step 143 also helps guide airflow, allowing it to flow more naturally into the enclosure 10.

[0053] In an embodiment of this utility model, the hard disk enclosure 100 further includes a plurality of foot pads 50, and the bottom surface of the lower shell 14 is provided with a plurality of mounting grooves (not shown in the figure). The foot pads 50 are installed in the mounting grooves and protrude from the bottom surface of the lower shell 14.

[0054] Furthermore, by setting the feet 50, the stability of the hard drive enclosure 100 can be increased, preventing it from sliding on the desktop and ensuring that the hard drive enclosure 100 is more stable during use. At the same time, the feet 50 can raise the enclosure 10, so that the air inlet 141 is kept at a certain distance from the desktop, avoiding being blocked by the desktop, and ensuring that cool air can enter the hard drive enclosure 100 more smoothly.

[0055] In this embodiment, as Figure 2 The foot pad 50 cooperates with the conical step 143, and the foot pad 50 is connected to the bottom surface of the conical step 143, making the air intake smoother. In addition, the foot pad 50 is arranged in an arc shape, and multiple foot pads 50 are arranged around the conical step 143, making the placement more stable.

[0056] In one embodiment, such as Figure 4 The upper shell 13 includes a top surface and a side surface. The top surface of the upper shell 13 is directly opposite the bottom surface of the lower shell 14. The exhaust vent 131 is located on the side surface of the upper shell 13. The cooling fan 20 and the hard drive assembly 30 are directly opposite each other along the connection direction between the upper shell 13 and the lower shell 14. That is, the air inlet is located on the bottom surface of the enclosure 10, and the exhaust vent 131 is located on the side surface of the enclosure 10. The airflow path is longer, which can more fully cover the surface of the hard drive assembly 30 and improve the heat dissipation effect.

[0057] In another embodiment, the cooling fan 20 is a turbine fan, and the turbine fan outlet 21 is connected to the exhaust port 131. The turbine fan has higher air pressure and air volume, which can more effectively deliver cool air into the hard drive enclosure 100 and improve heat dissipation efficiency; its compact design makes the turbine fan occupy less space, which is suitable for the design of compact hard drive enclosure 100.

[0058] In an embodiment of this utility model, the lower shell 14 further includes a connecting side 144, on which a buckle 145 protrudes. The inner side wall of the upper shell 13 is provided with a slot (not shown in the figure). The upper shell 13 partially covers the lower shell 14, and the lower shell 14 is engaged with the slot by the buckle 145 to connect to the upper shell 13.

[0059] It is worth noting that the connection between the upper shell 13 and the lower shell 14 can be either a snap-fit ​​connection or a threaded connection. For example... Figure 6 The lower shell 14 is also provided with a connecting side 144, and the upper shell 13 can cover the outside of the lower shell 14. The connecting side 144 is provided with a buckle 145, and the inner side wall of the upper shell 13 is provided with a slot. During installation, the upper shell 13 is engaged with the slot through the buckle 145 to be installed on the lower shell 14. The connection is stable and easy to install and remove.

[0060] In an embodiment of this utility model, the hard disk assembly 30 includes an adapter plate 31 and a hard disk body 32. The adapter plate 31 is disposed in the heat dissipation area 12, the hard disk body 32 is connected to the adapter plate 31, and the cooling fan 20 is electrically connected to the adapter plate 31.

[0061] Specifically, the adapter board 31 is located within the heat dissipation area 12, which can centrally handle the heat generated by the hard drive body 32. The cooling fan 20 is electrically connected to the adapter board 31 to power its rotation. The adapter board 31 can also integrate the hard drive body 32 with other components (such as power interfaces, data interfaces, etc.), allowing the hard drive assembly 30 to be compactly installed within the heat dissipation area 12, improving space utilization. The adapter board 31 can support various types of hard drives, improving device compatibility and expandability.

[0062] In one embodiment, a heat dissipation heat sink 40 is applied to the surface of the hard disk body 32 to directly dissipate heat from the hard disk body 32, resulting in good heat dissipation and better protection of the hard disk body 32 from overheating damage.

[0063] In an embodiment of this utility model, the hard disk body 32 includes a first hard disk 321 and a second hard disk 322. The first hard disk 321 and the second hard disk 322 are spaced apart on the adapter plate 31 and are both electrically connected to the adapter plate 31.

[0064] It is worth noting that the hard drive itself (32) can be configured as a single hard drive, such as... Figure 4 As shown. It can also be configured with two hard drives, namely the first hard drive 321 and the second hard drive 322, as shown. Figure 5As shown. When set to dual-bay configuration, adapter board 31 connects two hard drives together, significantly increasing storage capacity. Only one connection cable is needed for operation. Adapter board 31 is equipped with a Type-C interface.

[0065] The hard drive body 32 can be configured as a single hard drive or dual hard drives (i.e., the first hard drive 321 and the second hard drive 322). The single-drive configuration provides moderate storage capacity and efficient heat dissipation, suitable for general users. The dual-drive configuration significantly increases storage capacity. Heat can be centrally handled by the adapter board 31 and the cooling fan 20, ensuring that both hard drives are kept at a low temperature, which is suitable for professional users or enterprise environments that require a large amount of storage space and high performance.

[0066] In an embodiment of this utility model, the hard disk assembly 30 further includes a heat dissipation silicone pad 33, which is connected to the side of the adapter plate 31 opposite to the hard disk body 32.

[0067] In detail, a heat dissipation silicone pad 33 is also provided between the adapter plate 31 and the lower shell 14. The heat dissipation silicone pad 33 has good thermal conductivity and can quickly conduct the heat generated by the adapter plate 31 and the hard drive body 32 to the air duct and the lower shell 14. The airflow formed by the cooling fan 20 can quickly carry the heat on the lower shell 14 out of the hard drive enclosure 100, further enhancing the heat dissipation effect.

[0068] The upper shell 13 and lower shell 14 are typically made of metal, which has good thermal conductivity and can quickly dissipate heat. For example... Figure 6 and Figure 7 Multiple layers of heat dissipation silicone pads 33 are stacked to form multi-level heat conduction paths. Each layer of heat dissipation silicone pads 33 can further distribute and conduct heat evenly, improving the overall heat conduction efficiency.

[0069] In an embodiment of the present invention, the box body 10 is provided with a dustproof part 15 protruding into the air inlet 141. The dustproof part 15 is spaced apart from the air inlet 141 and at least partially coincides with the horizontal projection plane of the air inlet 141.

[0070] Specifically, such as Figure 3 and Figure 6 By setting up the dustproof part 15, the dustproof part 15 can effectively block external dust from entering the hard drive enclosure 100, reduce the impact of dust on the hard drive assembly 30, and extend the service life of the hard drive.

[0071] The dustproof section 15 overlaps with the air inlet 141, but is also spaced apart from the air inlet 141. This ensures that dust is intercepted before it enters, while not completely blocking the air inlet 141. This ensures that cold air can smoothly enter the hard drive enclosure 100, guaranteeing sufficient airflow without significantly affecting the airflow path and airflow volume.

[0072] In addition, such as Figure 4 When multiple air inlets 141 are provided, multiple dustproof sections 15 are also provided accordingly to improve the dustproof effect.

[0073] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
