Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a heat sink bracket that facilitates the installation of a fan. Background Technology

[0002] With the continuous improvement of electronic device performance and the increasing integration, chip heat dissipation has gradually become a key factor affecting device stability and lifespan. Early chip heat dissipation relied mainly on natural cooling or simple passive cooling methods, such as adding metal heat sinks to the chip surface to dissipate heat into the surrounding environment through natural convection. However, with the increase in chip power consumption, these traditional heat dissipation methods can no longer meet the heat dissipation requirements. Therefore, active cooling technologies have emerged, such as fan cooling and heat pipe cooling, which significantly improve heat dissipation efficiency through forced convection or phase change heat transfer.

[0003] In existing technologies, the I-shaped heatsink is one of the most commonly used heatsinks. It is generally made of thermally conductive material. During use, the upper and lower surfaces of the I-shaped heatsink need to contact the chassis and the chip respectively, thereby transferring heat from the chip to the chassis. Adding a fan to the heatsink can significantly improve its cooling efficiency. However, how to connect the fan to the heatsink during installation is a problem that needs to be solved. If bolts are used, mounting holes need to be drilled in the fan, which is inconvenient. Clip-on connections are not secure enough. Therefore, a heatsink that facilitates fan installation is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat sink bracket that facilitates fan installation, which effectively solves the aforementioned problems.

[0005] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A heat sink bracket for easy fan installation is provided, comprising a heat sink bracket and a fan assembly; the heat sink bracket includes an upper horizontal plate, a lower horizontal plate, and a vertical plate connecting the upper and lower horizontal plates; the fan is disposed between the upper and lower horizontal plates and faces the vertical plate; the fan assembly includes a housing for mounting fan blades; a positioning rod is longitudinally rotatably provided on the rear side wall of the housing, and the positioning rod is detachably connected to the rear side wall of the housing; the upper horizontal plate is provided with a clearance groove to avoid the upper end of the positioning rod, and a nut adapted to the upper end of the positioning rod is also provided in the clearance groove; after the positioning rod is rotated into position, the nut locks the positioning rod in the clearance groove; the lower end of the housing is fixedly connected to the lower horizontal plate.

[0007] This utility model provides a heat sink bracket for easy fan installation. The heat sink bracket for easy fan installation also includes screws for fixing the lower horizontal plate to the PBCA plate. The lower end of the outer shell is provided with a mounting seat facing forward horizontally. The screws pass through the mounting seat, the lower horizontal plate and the PBCA plate in sequence, and fasten the mounting seat to the lower horizontal plate and the lower horizontal plate to the PBCA plate.

[0008] This utility model provides a heat dissipation bracket for easy fan installation, wherein the upper horizontal plate has a longitudinally extending mounting hole located directly above the mounting base.

[0009] This utility model discloses a heat sink bracket for easy fan installation. The lower end of the back of the outer shell is provided with mounting plates for mounting a positioning rod. There are two mounting plates, which are respectively located on the left and right sides of the positioning rod. The lower end of the positioning rod is provided with a rotating shaft, and the two ends of the rotating shaft are rotatably connected to the two mounting plates respectively.

[0010] This utility model provides a heat sink bracket for easy fan installation, wherein the rear side wall of the outer shell is provided with a snap-fit ​​block for the positioning rod to be engaged.

[0011] This utility model provides a heat sink bracket for easy fan installation, wherein the rear side wall of the snap-fit ​​block is provided with a notch for the positioning block to enter the snap-fit ​​block, and the notch is provided with a guide slope for guiding the positioning rod.

[0012] This utility model provides a heat dissipation bracket for easy fan installation, wherein there are multiple vertical plates arranged sequentially from left to right.

[0013] The beneficial effects of this invention are as follows: The heat sink provided by this invention adds a fan assembly, changing the heat dissipation method from passive conduction to active heat dissipation. The fan is positioned facing the vertical plate, effectively dissipating the heat conducted by the heat sink to the surrounding environment through forced convection, enhancing the heat dissipation effect and ensuring that the chip can maintain a relatively stable temperature range during high-power operation, which is beneficial for improving chip performance and lifespan.

[0014] Furthermore, once the positioning rod is locked to the nut in the clearance groove, the position of the fan can be firmly fixed. At the same time, the lower end of the outer casing is fixedly connected to the lower horizontal plate, forming a double fixing structure. This effectively prevents the fan from shifting or loosening due to vibration or external force during operation, ensuring the stability of the overall structure of the heat sink, ensuring the continuity and reliability of the heat dissipation process, and further improving the heat dissipation effect and the stability of the equipment.

[0015] Meanwhile, both the top and bottom ends of the fan assembly are connected to the heat sink via bolts, which effectively ensures the stability of the connection structure. This not only avoids the problem of insufficient stability of the snap-fit ​​connection, but also avoids the cumbersome steps of drilling mounting holes on the fan required by traditional bolt connections. This simplifies the installation process, greatly improves installation efficiency, and reduces installation difficulty and time costs. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] A preferred embodiment of the present invention provides a heat sink 1 for convenient fan installation, such as... Figures 1-3 As shown, the device includes a heat sink 1 and a fan assembly 2. The heat sink 1 includes an upper horizontal plate 10, a lower horizontal plate 11, and a vertical plate 12 connecting the upper horizontal plate 10 and the lower horizontal plate 11. The upper horizontal plate 10, the lower horizontal plate 11, and the vertical plate 12 are all made of thermally conductive silicone. The fan is located between the upper horizontal plate 10 and the lower horizontal plate 11 and faces the vertical plate 12. The fan assembly 2 includes a housing 20 for mounting fan blades 21. A positioning rod 22 is longitudinally rotatably provided on the rear side wall of the housing 20. The positioning rod 22 is detachably connected to the rear side wall of the housing 20. The upper end of the positioning rod 22 is provided with an external thread. The upper horizontal plate 10 is provided with a clearance groove 100 to avoid the upper end of the positioning rod 22. A nut 13 adapted to the external thread of the upper end of the positioning rod 22 is also provided in the clearance groove 100. After the positioning rod 22 is rotated into place, the nut 13 locks the positioning rod 22 in the clearance groove 100. The lower end of the housing 20 is fixedly connected to the lower horizontal plate 11.

[0027] The clearance groove 100 is located on the front side of the upper surface of the upper horizontal plate 10 and one end penetrates the front side wall of the upper horizontal plate 10. The bottom surface of the clearance groove 100 is provided with a through hole 102 for the positioning rod 22 to pass through. The diameter of the through hole 102 is smaller than the diameter of the nut 13. The nut 13 is located inside the clearance groove 100. The depth of the clearance groove 100 is greater than the depth of the nut 13. When the upper horizontal plate 10 and the lower horizontal plate 11 are in close contact with the housing and the PBCA plate respectively, the nut 13 located inside the clearance groove 100 can protect the outer wall of the housing from being scratched by the nut 13.

[0028] In this embodiment, the heat sink 1 for easy fan installation also includes screws 14 for fixing the lower horizontal plate 11 to the PBCA plate; the lower end of the housing 20 is provided with a mounting base 24 facing forward horizontally, and the screws 14 pass through the mounting base 24, the lower horizontal plate 11 and the PBCA plate in sequence, and fasten the mounting base 24 to the lower horizontal plate 11 and the lower horizontal plate 11 to the PBCA plate; this installation method is simple and quick, and the process of installing the fan assembly 2 onto the lower horizontal plate 11 is also completed in the process of installing the lower horizontal plate 11 onto the PBCA plate, which simplifies the installation process and makes the installation simple and convenient.

[0029] In this embodiment, the upper horizontal plate 10 has a longitudinally extending mounting hole 101 located directly above the mounting base 24, providing a more convenient way to install the heat sink 1. The mounting hole 101's location directly above the mounting base 24 allows installers to insert screws 14 into the mounting base 24 through the mounting hole 101 and tighten them with a screwdriver inserted through the mounting hole 101. Furthermore, the use of the lower horizontal plate 11 and the PBCA plate enables rapid positioning and installation of the heat sink 1, improving installation efficiency and reducing installation difficulty and time costs.

[0030] In this embodiment, the lower end of the back of the outer casing 20 is provided with mounting plates 25 for mounting the positioning rod 22. There are two mounting plates 25, which are respectively located on the left and right sides of the positioning rod. The lower end of the positioning rod is provided with a rotating shaft (not shown in the figure), and the two ends of the rotating shaft are rotatably connected to the two mounting plates 25 respectively. This realizes the flexible rotation and positioning of the positioning rod 22, and improves the installation accuracy and stability of the fan assembly 2.

[0031] In this embodiment, the rotating shaft, two mounting plates 25, positioning rod 22, clearance groove 100 and nut 13 form a positioning unit. There are at least two positioning units, which further improves the stability and reliability of the connection between the heat sink 1 and the fan.

[0032] In this embodiment, a snap-fit ​​block 23 is provided on the rear side wall of the outer casing 20 for the positioning rod 22 to be snapped into; the positioning rod 22 can be easily snapped into the snap-fit ​​block 23 and connected to the outer casing 20, realizing the rapid positioning and fixing of the positioning rod 22, improving installation efficiency and reducing installation difficulty.

[0033] In this embodiment, the rear side wall of the snap-fit ​​block 23 is provided with a notch for the positioning block to enter the snap-fit ​​block 23. The notch is provided with a guide slope 230 for guiding the positioning rod 22. The diameter of the notch is smaller than the diameter of the positioning rod 22. This design makes the installation of the positioning rod 22 smoother. With the guidance of the guide slope 230, the positioning rod 22 can easily enter the snap-fit ​​block 23, reducing the installation difficulty.

[0034] In this embodiment, multiple vertical plates 12 are arranged sequentially from left to right. They not only connect and transfer heat from the lower horizontal plate 11 to the upper horizontal plate 10, aiding in chip heat dissipation, but also form an airflow channel for the airflow emitted by the fan assembly 2, making the heat dissipation effect of the heat sink 1 more significant. Preferably, there are two vertical plates 12. The airflow formed by the two vertical plates 12 guides the airflow blown by the fan blades 21, enhancing the heat dissipation effect and ensuring that the chip can maintain a relatively stable temperature range during high-power operation, which is beneficial for improving chip performance and lifespan.
