[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0030] The utility model embodiment provides a mobile hard disk 1, such as Figures 1 to 5As shown, the mobile hard disk 1 includes a housing 11, a PCB board 12, a hard disk 13 and an air flow driving member 14; the PCB board 12 is installed in the housing 11, and divides the interior of the housing 11 into a first cavity 111a and a second cavity 111b, and the first cavity 111a is connected to the second cavity 111b; the housing 11 is provided with a first air inlet 111c and a first air outlet 111d, the first air inlet 111c is connected to the first cavity 111a or the second cavity 111b, and the first air outlet 111d is connected to the first cavity 111a or the second cavity 111b; the hard disk 13 is installed on the PCB board 12 and is located in the first cavity 111a or the second cavity 111b, and the air flow driving member 14 is installed in the housing 11. Driven by the air flow driving member 14, the outside air enters the first cavity 111a through the first air inlet 111c, flows through the second cavity 111b, and then flows out from the first air outlet 111d.

[0031] The mobile hard disk 1 of the utility model divides the internal space of the housing 11 into a first cavity 111a and a second cavity 111b that are connected through the PCB board 12, and a first air inlet 111c and a first air outlet 111d are provided correspondingly. At the same time, driven by the airflow driving member 14, the outside air enters the first cavity 111a through the first air inlet 111c, flows through the second cavity 111b, and then flows out from the first air outlet 111d. In this way, the airflow can take away the heat generated by the components of the PCB board 12 and the hard disk 13 from both sides of the PCB board 12, and the structure is simple and the heat dissipation effect is good.

[0032] Specifically, the utility model is simple and efficient through the design of separating the cavity and the airflow, which ensures good heat dissipation effect of the mobile hard disk 1 during use. By cooling the components and hard disk 13 inside the mobile hard disk 1, the stability and reliability of the mobile hard disk 1 can be improved, and its service life can be extended. Specifically, the hard disk 13 can be a solid-state drive 13 (SSD) or a mechanical hard disk 13 (HDD).

[0033] Specifically, the first air inlet 111c can be communicated with the first cavity 111a or the second cavity 111b. The first air outlet 111d can be communicated with the first cavity 111a or the second cavity 111b. The hard disk 13 can be installed on the side of the PCB board 12 close to the first cavity 111a or the side of the PCB board 12 close to the second cavity 111b.

[0034] like Figure 6As shown, a gap 15 is formed between the edge of the housing 11 and the PCB board 12, and the first cavity 111a and the second cavity 111b are connected through the gap 15. The first cavity 111a and the second cavity 111b can be connected to each other through the gap 15 between the edge of the housing 11 and the PCB board 12. This connectivity ensures that the air flow path from the first air inlet 111c to the first air outlet 111d is unobstructed, so that the air can effectively flow through the hard disk 13 and the PCB board 12. Through the connected first cavity 111a and the second cavity 111b, air can flow through the inside of the mobile hard disk 1 and take away the heat generated by the hard disk 13 and the PCB board 12. This improves the heat dissipation effect of the mobile hard disk 1, helps to keep the temperature of the mobile hard disk 1 within an acceptable range, and improves the performance and reliability of the hard disk 13. In addition, the gap 15 between the edge of the housing 11 and the PCB board 12 can simplify the structural design of the entire mobile hard disk 1. Compared with directly opening vias or other complex connection channels on the PCB board 12, it is simpler to achieve the connection between the first cavity 111a and the second cavity 111b through the gap 15. The simplified structure not only reduces the cost and manufacturing complexity, but also improves the reliability and maintainability of the mobile hard disk 1. More specifically, the gap 15 is formed around the edges of the shell 11 and the PCB board 12. The gap 15 is formed around the edges of the shell 11 and the PCB board 12, so that air can enter and flow through the second cavity 111b from all directions of the first cavity 111a, and the air flow between the first cavity 111a and the second cavity 111b is more sufficient. This multi-directional air flow helps to better dissipate heat, thereby effectively cooling the components inside the mobile hard disk 1.

[0035] Specifically, the first air inlet 111c and the first air outlet 111d are both connected to the first cavity 111a, and the first air inlet 111c is located at one end of the first cavity 111a, and the first air outlet 111d is located at the other end of the first cavity 111a; the air flow driving member 14 is a turbine fan, which is installed in the first cavity 111a and located at one end close to the first air outlet 111d; the air inlet of the turbine fan is connected to the second cavity 111b, and the air outlet of the turbine fan is connected to the first air outlet 111d.

[0036] The first air inlet 111c and the first air outlet 111d are connected to the first cavity 111a, and the first air inlet 111c and the first air outlet 111d are located at both ends, and the air inlet of the turbo fan is connected to the second cavity 111b, and the air outlet of the turbo fan is connected to the first air outlet 111d. This allows the air to enter the first cavity 111a through the first air inlet 111c after the turbo fan is started, and then flow through the second cavity 111b and be drawn out from the first air outlet 111d through the turbo fan. The air flow path is long, which improves the air circulation efficiency and heat dissipation effect. The air can fully flow through every corner of the first cavity 111a and the second cavity 111b, so that the heat from various places can be fully taken away, thereby improving the heat dissipation effect of the entire mobile hard disk 1.

[0037] The PCB board 12 is provided with a wind opening 121 corresponding to the position of the turbine fan, and the air inlet of the turbine fan is connected to the wind opening 121. The PCB board 12 is provided with a wind opening 121 corresponding to the position of the turbine fan, so that the air inlet of the turbine fan is connected to the second cavity 111b. Specifically, the hard disk 13 is installed on the side of the PCB board 12 facing the second cavity 111b, and other components can be installed on the other side of the PCB board 12.

[0038] The housing 11 includes a heat sink 112, which is located on a side corresponding to the hard disk 13. The heat sink 112 can transfer the heat generated inside the hard disk 13 to the external environment. The heat sink 112 is located on a side corresponding to the hard disk 13, which can absorb and disperse the heat generated by the hard disk 13 more directly and quickly, and can more effectively dissipate the heat generated by the hard disk 13. Through such a position arrangement, the heat inside the hard disk 13 can be quickly transferred to the heat sink 112. The heat sink 112 can be a metal that is easy to dissipate heat, such as aluminum alloy, copper, etc. Further, the mobile hard disk 1 also includes a heat conductor 16, one side of the heat conductor 16 is in contact with the hard disk 13, and the other side is in contact with the heat sink 112. The heat conductor 16 has good thermal conductivity and can help conduct heat. One side of the heat conductor 16 is in contact with the hard disk 13. By connecting with the hard disk 13, the heat conductor 16 can effectively absorb and conduct the heat generated by the hard disk 13. The heat inside the hard disk 13 can be quickly transferred to the heat conductor 16, and its thermal conductivity is used for heat dissipation. The other side of the heat conductor 16 is in contact with the heat sink 112. By being connected to the heat sink 112, the heat conductor 16 can effectively transfer the heat absorbed by the hard disk 13 to the heat sink 112. The heat sink 112 can disperse the heat to the surrounding environment through its larger surface area and better heat dissipation performance. The heat conductor 16 can be made of a heat-conducting material, such as copper, aluminum or a heat-conducting adhesive, thermal grease, etc. Specifically, the housing 11 also includes a base 111, a first air inlet 111c and a first air outlet 111d are respectively arranged on the two end surfaces of the base 111, the heat sink 112 is covered on the base 111, and the mounting frame 17 is snapped into the base 111 through a snap structure.

[0039] The mobile hard disk 1 also includes a mounting frame 17, which is mounted in the housing 11, and the PCB board 12 is mounted on the mounting frame 17; a first opening 171 corresponding to the hard disk 13 is opened on the mounting frame 17, and the heat conductive member 16 contacts the hard disk 13 and the heat sink 112 in the first opening 171. The mounting frame 17 is installed in the housing 11 of the hard disk 13, and the PCB board 12 is installed on the mounting frame 17. Through such an installation method, the core component of the mobile hard disk 1, the PCB board 12, can be fixed on the mounting frame 17, providing a stable support structure to ensure the normal operation of the hard disk 13. A first opening 171 corresponding to the hard disk 13 is further opened on the mounting frame 17, so that the heat conductive member 16 can contact the hard disk 13 and the heat sink 112 respectively.

[0040] Further integration Figure 7As shown, the surface of the heat sink 112 is provided with a plurality of heat dissipation ridges 112a arranged side by side at intervals, and the mobile hard disk 1 also includes an outer cover plate 18, which is installed on the surface of the heat sink 112 and covers the heat dissipation ridges 112a to form a heat dissipation channel 112b with openings at both ends. In this solution, the surface of the heat sink 112 is provided with a plurality of heat dissipation ridges 112a arranged side by side at intervals. The presence of these heat dissipation ridges 112a can increase the surface area of ​​the heat sink 112 and improve the heat dissipation effect. The heat dissipation ridges 112a with a raised structure can also increase the surface area of ​​air flow and improve the heat dissipation efficiency. The outer cover plate 18 is installed on the surface of the heat sink 112 and covers the heat dissipation ridges 112a. The installation of the outer cover plate 18 can protect the heat dissipation ridges 112a from damage by external objects, and at the same time form a heat dissipation channel 112b. Through the combination of the outer cover plate 18 and the heat dissipation ridges 112a, a heat dissipation channel 112b with openings at both ends is formed. The heat dissipation channel 112 b provides a path for air flow, so that heat can be dissipated through the heat dissipation ribs 112 a and the heat dissipation channel 112 b.

[0041] like Figure 8 As shown, the utility model also discloses a mobile hard disk kit, including the mobile hard disk 1 and the protective cover 2, the protective cover 2 can be set on the mobile hard disk 1, and the protective cover 2 can play a role in protecting the mobile hard disk 1.
