Abstract
Description
Technical Field
[0001] This invention relates to the field of portable hard drive technology, specifically to an actively cooled dual-unit independent portable hard drive. Background Technology
[0002] A portable hard drive is a storage product that uses a hard drive as its storage medium for exchanging large amounts of data between computers, emphasizing portability. The vast majority of portable hard drives on the market are based on standard hard drives, with only a small portion using micro hard drives (such as 1.8-inch hard drives). However, price factors dictate that the mainstream portable hard drives are still based on standard laptop hard drives. Because they use hard drives as the storage medium, portable hard drives operate in the same data read / write mode as standard IDE hard drives. Portable hard drives mostly use high-speed interfaces such as USB, allowing for high-speed data transfer with the system. Currently, most portable hard drives lack cooling devices, causing the hard drive to overheat during prolonged use and reducing its lifespan. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide an active heat dissipation dual-body independent mobile hard drive.
[0004] To solve the above-mentioned technical problems, the present invention provides a dual-body independent mobile hard drive with active heat dissipation: including a housing and a solid-state drive disposed within the housing. A fan is built into the upper right side of the housing, and a fan is built into the lower left side of the housing. An upper cover is provided on the upper left side of the housing, and a lower cover is provided on the lower right side of the housing. A PCB board is provided between the upper cover and the second fan, and a main control chip is provided on the PCB board. The solid-state drive is provided between the first fan and the lower cover.
[0005] Furthermore, an interface is built into the left side of the housing.
[0006] Furthermore, the solid-state drive is electrically connected to the interface via a PCB board, and the first fan and the second fan are electrically connected to the PCB board.
[0007] Furthermore, both the upper and lower covers are made of ceramic.
[0008] The advantages of this invention compared with the prior art are: the invention has a reasonable structural layout, compact structure, small size, and is easy to carry. It is also equipped with dual fans, which can dissipate heat for the phone and itself at the same time, and the heat dissipation speed is fast. Therefore, it can improve the performance of both the phone and itself during use, and has a long service life. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0014] Example 1, in conjunction with Appendix Figure 1-2 An actively cooled dual-unit independent portable hard drive includes a housing 1 and a solid-state drive 2 housed within the housing 1. A fan 3 is built into the upper right side of the housing 1, and a second fan 4 is built into the lower left side of the housing 1. An upper cover 5 is located on the upper left side of the housing 1, and a lower cover 6 is located on the lower right side of the housing 1. A PCB board 7 is located between the upper cover 5 and the second fan 4, and a main control chip 8 is mounted on the PCB board 7. The solid-state drive 2 is located between the first fan 3 and the lower cover 6. An interface 9 is built into the left side of the housing 1. In use, one end of a data cable is inserted into interface 9, and the other end is inserted into a device such as a mobile phone or computer for data transfer. Simultaneously, the first fan 3 and the second fan 4 operate to cool the portable hard drive itself. When connected to a mobile phone for data transfer, the portable hard drive can be placed on the back of the phone to help cool the phone. The type of interface 9 can be selected according to actual needs, such as a MicroUSB interface, a Type-C interface, or a Lightning interface.
[0015] The solid-state drive 2 and the interface 9 are electrically connected through the PCB board 7, and the fan 3 and the fan 4 are electrically connected to the PCB board 7.
[0016] Both the upper cover 5 and the lower cover 6 are made of ceramic plates, which have good thermal conductivity and can dissipate heat faster.
[0017] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0018] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0019] In the description of the embodiments of the present invention, "multiple" means at least two.
[0020] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
