Description

Technical Field

[0001] This utility model relates to a heat dissipation device for a hard drive enclosure, belonging to the technical field of hard drive enclosures for electronic computers. Background Technology

[0002] With the rapid development of the internet and multimedia, people are increasingly encountering large-capacity data exchanges measured in gigabytes. For such massive amounts of data, hard drives are undoubtedly the best carrier. However, ordinary hard drives are installed in computer cases and contain the operating system, making them difficult to move. Hard drive enclosures provide physical protection for a hard drive while using a convenient connection method, enabling the function of a portable hard drive. Currently, existing computer hard drive enclosures have poor heat dissipation performance. When users use these enclosures, the internal hard drive is prone to overheating. Existing products do not directly cool the hard drive and the main control board; they only rely on fans to blow heat outwards or only blow air across the hard drive surface without heat sinks, failing to simultaneously cool both the hard drive and the main control board. This results in low heat dissipation efficiency, remaining at the stage of passive cooling. Chinese Patent Publication No. CN217239042U discloses a computer hard drive enclosure with good heat dissipation performance, relating to the field of computer hard drive enclosures. The enclosure includes a shell, with L-shaped fixing blocks fixedly connected to both sides of the inner cavity of the shell. A hard drive body is fixedly connected to the top of the L-shaped fixing blocks. A heat-absorbing device is provided at the bottom of the hard drive body, and a heat-dissipating device is provided at the bottom of the heat-absorbing device. A motor is fixedly connected to the left side of the bottom of the inner cavity of the shell, and a rotating shaft is fixedly connected to the output end of the motor. This invention provides a computer hard drive enclosure with good heat dissipation performance. During heat dissipation, thermal grease and thermally conductive silicone cloth absorb the heat generated by the hard drive body, and simultaneously, the thermal grease and thermally conductive silicone cloth guide the heat into the metal heat sink, allowing the metal heat sink to dissipate the heat. The thermal paste can increase the heat dissipation speed of the metal heat sink. However, in the use of existing technology, the fan blades of its heat dissipation device only blow heat on one side of the hard drive body, and the heated air inside the hard drive enclosure will gather upwards, resulting in a lack of circulation between the external air and the gas inside the hard drive enclosure. Therefore, the heat dissipation effect of the hard drive enclosure needs to be improved. To this end, a heat dissipation device for hard drive enclosure is proposed. Summary of the Invention

[0003] In view of this, the present invention provides a heat dissipation device for a hard drive enclosure to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0004] The technical solution of this utility model is as follows: a heat dissipation device for a hard drive enclosure, comprising a hollow shell and a cover plate; The hollow shell and the cover plate are detachably connected; The hollow shell has a first air inlet, a second air inlet, and a third air inlet symmetrically opened on both sides. Two main air outlets are opened on one side of the hollow shell. A base and a mounting seat are fixedly connected inside the hollow shell. A hard drive body is mounted on the mounting seat, and a fan is mounted on the base. Several heat sinks are fixedly connected to the hard drive body. A first guide plate and a second guide plate are fixedly connected to one side of the cover plate. The adjacent sides of the first and second guide plates are respectively attached to the heat sinks. A fixing plate is fixedly connected to one side of the cover plate. Horizontal plates are fixedly connected to both sides of the fixing plate. One side of each horizontal plate is fixedly connected to the cover plate. The fixing plate and the horizontal plates are tightly fitted to the outer contour of the fan in a wrapping manner.

[0005] More preferably, the number of the fixing bases is four, and each of the four fixing bases is provided with a second threaded hole that mates with a screw. The hard disk body is threadedly connected to the second threaded hole by a screw and is detachably fixed to the fixing base. The base is provided with at least one first threaded hole, and the fan is threadedly engaged with the first threaded hole by a screw, thereby realizing a detachable fixed connection between the fan and the base. The fan is installed upside down.

[0006] More preferably, the fixing base forms a height difference with the opening plane of the first air inlet, the second air inlet and the third air inlet in the vertical direction, wherein the vertical height of the fixing base is greater than the opening plane height of the first air inlet, the second air inlet and the third air inlet.

[0007] More preferably, the hollow shell has a sliding groove, and a through hole is provided on one side of the hollow shell.

[0012] The present invention has the following advantages due to the adoption of the above technical solution: This invention utilizes a heat sink mounted on the hard drive body to quickly transfer the heat generated during operation to the heat sink. A matching fan then drives a directional airflow, forcing convection heat transfer through the heat conducted by the heat sink, which is then exhausted through the main exhaust vent. Simultaneously, because the fan is inverted, it draws external air into the bottom area of ​​the hard drive body through the first, second, and third air inlets and blows it out onto the heat sink, creating a bottom-up air circulation path and forming a bidirectional airflow channel.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, this utility model embodiment provides a heat dissipation device for a hard drive enclosure, including a hollow shell 10 and a cover plate 20; In one embodiment, to facilitate the installation of the hollow housing 10 and the cover plate 20, the hollow housing 10 and the cover plate 20 are detachably connected. To facilitate the entry of external air into the hollow housing 10 and the exhaust of air from inside the hollow housing 10, a first air inlet 11, a second air inlet 12, and a third air inlet 13 are symmetrically provided on both sides of the hollow housing 10, and two main air outlets 14 are provided on one side of the hollow housing 10. To facilitate the installation of the hard disk body 30 and the fan 31, and to facilitate the formation of a dual-channel airflow for the hard disk body 30 within the hollow housing 10, a fan 31 base 19 and a mounting base 17 are fixedly connected inside the hollow housing 10, and the hard disk body 31 is mounted on the mounting base 17. A fan 31 is mounted on the base 19 of the fan 31. In order to facilitate the heat conduction generated when the hard drive body 30 is driven, a number of heat sinks 32 are fixedly connected to the hard drive body 30. A first guide plate 21 and a second guide plate 22 are fixedly connected to one side of the cover plate 20. The adjacent sides of the first guide plate 21 and the second guide plate 22 are respectively attached to the heat sinks 32. In order to facilitate the formation of a sealed channel between the fan 31 and the hard drive body 30 in the hollow shell 10 and achieve a stable gas flow channel, a fixing plate 23 is fixedly connected to one side of the cover plate 20. Horizontal plates 24 are fixedly connected to both sides of the fixing plate 23. One side of the two horizontal plates 24 is fixedly connected to the cover plate 20. The fixing plate 23 and the horizontal plates 24 are tightly attached to the outer contour of the fan 31 in a covering manner.

[0022] In one embodiment, to facilitate the replacement and maintenance of the hard drive body 30 and the fan 31, four mounting bases 17 are provided. Each of the four mounting bases 17 is provided with a second threaded hole 104 that mates with a screw. The hard drive body 30 is detachably fixed to the mounting base 17 by screws threaded to the second threaded hole 104. The fan 31 base 19 is provided with at least one first threaded hole 103. The fan 31 is threadedly engaged with the first threaded hole 103 by screws, thereby achieving a detachable fixed connection between the fan 31 and the fan 31 base 19. The fan 31 is installed upside down. To facilitate the entry of external air into the hollow casing 10 to dissipate heat from the bottom of the hard drive body 30, the mounting base 17 forms a height difference with the opening planes of the first air inlet 11, the second air inlet 12, and the third air inlet 13 in the vertical direction. The vertical height of the mounting base 17 is greater than the opening plane heights of the first air inlet 11, the second air inlet 12, and the third air inlet 13.

[0023] In one embodiment, to facilitate the installation and removal of the hard drive enclosure, a sliding groove 18 is provided on the hollow housing 10, and a through hole 102 is provided on one side of the hollow housing 10. The through hole 102 penetrates the inner wall of the sliding groove 18, so that the through hole 102 communicates with the sliding groove 18. A slider 25 for inserting into the sliding groove 18 is fixedly connected to the cover plate 20. The slider 25 is provided with a third threaded hole 26. The cover plate 20 is connected by screws through the through hole 102 and threadedly engaged with the third threaded hole 26. In order to facilitate the balance of airflow in and out of the hollow housing 10 and achieve uniform gas flow, and also to facilitate the connection of the hard drive body 30 to external devices through the Type-C interface 16, an auxiliary air outlet 15 is provided on one side of the hollow housing 10, and a Type-C interface 16 is provided on the side of the hollow housing 10 near the auxiliary air outlet 15. In order to reduce the thickness of the hollow housing 10 and improve the hollow housing... To improve the heat dissipation of the body 10, the hollow housing 10 has equally spaced grooves 101 on both sides. In order to facilitate heat conduction of the heat sink 32 through the cover plate 20, and to improve the heat dissipation of the hollow housing 10 and the cover plate 20, the side of the heat sink 32 near the cover plate 20 is tightly attached to the surface of the cover plate 20. The heat sink 32 is a single-cut multi-groove design, 70mm long, 22mm wide, and 6mm thick, effectively covering the hard drive body 30, greatly increasing the heat dissipation area, and guiding the hot air blown out by the fan 31 to flow out of the hollow housing 10. In addition, the hard drive body 30 near the bottom main control area of ​​the hollow housing 10 has a 15mm*15mm*4mm heat sink 32. The air intake channel of the hollow housing 10 will flow through the heat sink 32 to dissipate heat in the main control area and then be drawn into the fan 31 and blown out onto the heat sink 32 of the hard drive body 30 above. Both the hollow housing 10 and the cover plate 20 are made of aluminum alloy.

[0024] In operation, this invention works as follows: During use, some of the heat generated by the hard drive body 30 during operation is conducted to the cover plate 20 via the heat sink 32. This heat is then driven by the matching fan 31 to generate airflow, which blows and exchanges heat between the heat sink 32 and the hard drive body 30, allowing the hot air to be exhausted through the main exhaust port 14. Additionally, some hot air is exhausted through the auxiliary exhaust port 15. Simultaneously, because the fan 31 is installed inverted, it can draw in external air into the bottom area of ​​the hard drive body 30 through the first air inlet 11, the second air inlet 12, and the third air inlet 13, blowing and cooling the bottom surface of the hard drive body 30. This creates a bottom-up air circulation path, forming a bidirectional airflow channel that covers the main control board and the hard drive, improving the heat dissipation effect of the hard drive enclosure. Furthermore, the cover plate 20 and the hollow shell 10 are detachably connected, facilitating future maintenance and upgrades of the hard drive body 30.
