Technical Field

[0001] This invention relates to the field of computer heat dissipation technology, and in particular to a heat sink structure. Background Technology

[0002] In the field of server R&D, heat sinks are often used to dissipate heat from server chassis. Different installation methods and installation gaps are used to dissipate heat for different heat dissipation needs.

[0003] In existing technologies, conventional heatsinks have a fixed structure, resulting in a fixed heat dissipation capacity for each fin. While widely used, conventional heatsinks cannot adapt to diverse cooling needs. Even minor changes to the server or its environment necessitate the selection of new heatsinks. Furthermore, different heatsinks are required for different usage environments, increasing operating costs and hindering flexible adaptation. In conclusion, existing heatsinks cannot meet a wide range of cooling requirements. Summary of the Invention

[0005] This invention provides a heat sink structure, comprising:

[0006] The mounting base plate has a mounting surface;

[0007] A heat dissipation assembly includes a heat dissipation base plate, on which are formed mating surfaces and heat dissipation surfaces arranged opposite each other. Multiple heat dissipation fins are protruding from the heat dissipation surface. The mating surface is movably mounted to the mounting base plate, forming an adjustable heat dissipation gap between the mating surface and the mounting surface.

[0008] The adjustment structure is located between the mating surface and the mounting surface to adjust the size of the heat dissipation gap.

[0009] According to the heat sink structure provided by the present invention, a threaded hole is provided on the mounting surface;

[0012] An adjusting screw, the threaded section of which passes through the first through hole and is threadedly connected to the threaded hole; and,

[0013] The first elastic element is located between the mating surface and the mounting surface. The first elastic element is used to drive the heat dissipation base plate to move, so that the heat dissipation surface moves to abut against the screw head of the adjusting screw.

[0014] The size of the heat dissipation gap is adjusted by rotating the adjusting screw.

[0015] According to the radiator structure provided by the present invention, the first elastic element includes a mounting spring, which is sleeved on the adjusting screw.

[0016] According to the radiator structure provided by the present invention, the threaded hole, the first through hole, the adjusting screw and the first elastic element together form an adjustment group, and multiple adjustment groups are provided.

[0017] According to the heat sink structure provided by the present invention, a second through hole is provided on the mating surface;

[0018] The adjustment structure includes a movable rod, which is mounted on the mounting surface;

[0019] The second through hole is movably sleeved on the movable rod, and has a first stop position and a second stop position for stopping the movement on the movable rod;

[0020] The heat dissipation base plate is stopped at either the first or second stop position to adjust the size of the heat dissipation gap.

[0021] According to the radiator structure provided by the present invention, the movable rod is rotatably mounted on the mounting surface, and a limiting block is protruding on the outer side wall of the movable rod;

[0022] Multiple locking teeth are protruding on the inner wall of the second through hole, and the multiple locking teeth are spaced apart along the circumference of the second through hole.

[0023] The movable rod rotates, causing the limiting block to abut against the locking tooth block to stop at the first position, or to move between two adjacent locking tooth blocks to stop at the second position.

[0024] According to the radiator structure provided by the present invention, the adjustment structure further includes a second elastic element, which drives the heat dissipation base plate to move axially along the movable rod, so that the locking tooth block abuts against the limiting block, or so that the limiting block is located between two adjacent locking tooth blocks.

[0025] According to the radiator structure provided by the present invention, the toothed block has an abutting end face that abuts against the limiting block, and a receiving groove is recessed on the abutting end face, the receiving groove being used to receive the limiting block.

[0026] A first guide slope is also formed on the abutting end face, and the first guide slope is inclined from one side edge of the abutting end face toward the receiving groove.

[0027] According to the heat sink structure provided by the present invention, a second guide slope is formed on the abutting end face, and the second guide slope is inclined from the opening of the receiving groove toward the other edge of the abutting end face.

[0028] According to the heat sink structure provided by the present invention, a mating slope is provided on the limiting block corresponding to the first guide slope.

[0029] In the heat sink structure provided by this invention, the mounting base plate has a mounting surface. The mounting base plate is installed on the external server to be cooled. The heat generated by the server is transferred from the mounting base plate to the heat sink base plate and dissipated through the heat sink fins. After the heat dissipation requirements or the surrounding environment are adjusted, the server needs to generate different heat dissipation rates. At this time, by adjusting the structure and adjusting the size of the heat dissipation gap, the heat exchange efficiency between the mounting base plate and the heat sink base plate is changed, forming heat dissipation at different rates to adapt to different heat dissipation requirements without replacing the heat sink.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] Please see Figure 1 The present invention provides a radiator structure 100, including a mounting base plate 1, a heat dissipation assembly 2, and an adjustment structure; the mounting base plate 1 has a mounting surface; the heat dissipation assembly 2 includes a heat dissipation base plate 21, on which a mating surface and a heat dissipation surface are formed oppositely arranged, and a plurality of heat dissipation fins 22 are protruding on the heat dissipation surface; the mating surface is movably mounted on the mounting base plate 1, forming an adjustable heat dissipation gap between it and the mounting surface; the adjustment structure is disposed between the mating surface and the mounting surface to adjust the size of the heat dissipation gap.

[0040] In the radiator structure 100 provided by the present invention, the mounting base plate 1 has a mounting surface. The mounting base plate 1 is installed on the external server to be cooled. The heat generated by the server is transferred from the mounting base plate 1 to the heat dissipation base plate 21 and dissipated through the heat dissipation fins 22. After the heat dissipation requirements or the surrounding environment are adjusted, the server needs to generate different heat dissipation rates. At this time, by adjusting the structure and adjusting the size of the heat dissipation gap, the heat exchange efficiency between the mounting base plate 1 and the heat dissipation base plate 21 is changed, forming heat dissipation at different rates to adapt to different heat dissipation requirements without replacing the radiator.

[0041] It should be noted that the smaller the heat dissipation gap, the higher the heat dissipation efficiency. In actual use, the appropriate heat dissipation gap should be selected according to the actual use of the server so that the server can complete heat dissipation and ensure the safety of the surrounding environment. Each type of server has its optimal heat dissipation efficiency after installation. In this embodiment, by adjusting the heat dissipation gap, the heat sink structure can have different heat dissipation efficiencies, which makes it easy to install in different servers without having to make molds for heat sinks for each server.

[0042] For further details, please refer to Figure 2In the first embodiment of the present invention, a threaded hole is provided on the mounting surface; a first through hole is provided on the mating surface; the adjustment structure includes an adjustment screw 31 and a first elastic element 32; the threaded section of the adjustment screw 31 passes through the first through hole and is threadedly connected to the threaded hole; the first elastic element 32 is disposed between the mating surface and the mounting surface, and the first elastic element is used to drive the heat dissipation base plate 21 to move, so that the heat dissipation surface moves against the screw head of the adjustment screw 31; wherein, rotating the adjustment screw 31 adjusts the size of the heat dissipation gap. In this embodiment, a first elastic element 32 is provided between the heat dissipation base plate 21 and the mounting base plate 1, so that the heat dissipation surface of the heat dissipation base plate 21 abuts against the screw head of the adjustment screw 31, and a heat dissipation gap is formed between the heat dissipation base plate 21 and the mounting base plate 1. When it is necessary to adjust the size of the heat dissipation gap, the adjustment screw 31 is rotated, so that the adjustment screw 31 moves toward or away from the mounting base plate 1, thereby driving the heat dissipation base plate 21 to move, adjusting the size of the heat dissipation gap, so as to adjust the heat dissipation rate of the heat sink structure 100.

[0043] Specifically, in this embodiment, the first elastic element 32 includes a mounting spring, which is sleeved on the adjusting screw 31. This facilitates the installation of the first elastic element 32 and the movement of the heat dissipation base plate 21. The structure is simple, reliable, and has a long service life.

[0044] It should be noted that, in order to facilitate a tight fit between the heat dissipation base plate 21 and the mounting base plate 1, a spring groove is recessed on the mounting surface of the mounting base plate 1, a threaded hole is provided on the bottom wall of the spring groove, and a spring sleeve is provided in the spring groove so that when the spring is compressed, the spring can retract into the spring groove, so that the heat dissipation base plate 21 and the mounting base plate 1 can fit tightly together.

[0045] Obviously, spring grooves can also be provided on the mating surface to accommodate the spring, which will not be elaborated here.

[0046] In addition, to facilitate the stable movement of the heat dissipation base plate 21, the threaded hole, the first through hole, the adjusting screw 31, and the first elastic element 32 together form an adjustment group, and multiple adjustment groups are provided. In this embodiment, the heat dissipation gap is adjusted through multiple adjustment groups, thereby improving the stability of the movement of the heat dissipation base plate 21 and preventing the heat dissipation base plate 21 from shaking and affecting heat dissipation.

[0047] In this embodiment, multiple adjustment groups are arranged at intervals along the circumference of the heat dissipation base plate 21 to ensure the stability of the heat dissipation base plate 21.

[0048] In the first embodiment described above, the heat dissipation gap is adjusted by rotating the screw, which is simple and reliable. The first elastic element presses the heat dissipation base plate 21 onto the screw head of the adjusting screw 31. By rotating the adjusting screw 31, the adjusting screw moves continuously toward the mounting base plate 1, compressing the first elastic element and adjusting the heat dissipation gap.

[0049] On the other hand, the present invention provides a second embodiment. In this embodiment, a second through hole is provided through the mating surface; the adjustment structure includes a movable rod 33, which is installed on the mounting surface; the second through hole is movably sleeved on the movable rod 33 and has a first stop position and a second stop position on the movable rod 33; wherein, the heat dissipation base plate 21 stops at the first stop position or the second stop position to adjust the size of the heat dissipation gap. In this embodiment, by stopping the heat dissipation base plate 21 at different positions on the movable rod 33, the size of the heat dissipation gap between the heat dissipation base plate 21 and the mounting base plate 1 is adjusted, forming two standard positions to facilitate a standardized heat dissipation rate and facilitate rapid switching.

[0050] For further details, please refer to Figure 3 The movable rod 33 is rotatably mounted to the mounting surface. A limiting block 331 protrudes from the outer wall of the movable rod 33. Multiple locking teeth 34 protrude from the inner wall of the second through hole, and the multiple locking teeth 34 are spaced apart circumferentially along the second through hole. The movable rod 33 rotates, causing the limiting block 331 to abut against the locking teeth 34 to stop at a first position, or to move between two adjacent locking teeth 34 to stop at a second position. In this embodiment, the second through hole is movably sleeved on the movable rod 33. A limiting block 331 is provided on the outer wall of the movable rod 33, and a locking tooth 34 is provided inside the second through hole. During use, the locking teeth 34 and the limiting block 331 abut against each other, thereby stopping the heat dissipation base plate 21 at the first stop position. When position adjustment is required, the movable rod 33 is rotated, causing the locking teeth 34 to disengage from the limiting block 331, and the heat dissipation base plate 21 is moved so that the limiting block 331 is between two adjacent locking teeth 34, reaching the second stop position.

[0051] Furthermore, in this embodiment, the adjustment structure also includes a second elastic element 35. The second elastic element 35 drives the heat dissipation base plate 21 to move axially along the movable rod 33, causing the locking tooth block 34 to abut against the limiting block 331, or causing the limiting block 331 to be positioned between two adjacent locking tooth blocks 34. In this embodiment, by driving the heat dissipation base plate to move axially along the movable rod 33 through the second elastic element 35, the locking tooth block 34 and the limiting block 331 are tightly pressed together. After the movable rod 33 rotates, the second elastic element 35 automatically drives the heat dissipation base plate 21 to move, causing the limiting block 331 to move relative to the two locking tooth blocks 34.

[0052] For details, please refer to Figure 4In the specific embodiment provided by the present invention, the toothed block 34 abuts against the limiting block 331 at the end facing the heat dissipation surface, and the second elastic member drives the heat dissipation base plate 21 to move away from the mounting base plate 1, so that the toothed block 34 and the limiting block 331 automatically abut against each other. At this time, the toothed block 34 abuts against the limiting block 331, and the heat dissipation base plate 21 is in the first stop position.

[0053] When making adjustments, please refer to Figure 5 Rotate the movable rod 33 so that the contact end face disengages from the limit block 331. At this time, under the action of the second elastic member 35, the heat dissipation base plate 21 continues to move away from the mounting base plate 1, and the limit block 331 moves to the space between two adjacent toothed blocks 34 and reaches the second stop position.

[0054] When it is necessary to return to the first stop position, the drive heat sink base plate 21 moves toward the mounting base plate 1, and then the movable rod 33 is rotated so that the limit block 331 and the locking tooth block 34 abut against each other again, thereby completing the return to the first stop position.

[0055] It should be noted that the second elastic element 35 is a spring, which is sleeved on the movable rod 33 to drive the heat dissipation base plate 21 to move.

[0056] Furthermore, to facilitate automatic adjustment, a recessed receiving groove is provided on the abutting end face to accommodate the limiting block 331; a first guide slope 341 is also formed on the abutting end face, which is inclined from one edge of the abutting end face toward the receiving groove. In this embodiment, to facilitate the automatic rotation of the limiting block 331 into the receiving groove and maintain contact with the abutting end face, the first guide slope 341 is provided on the abutting end face. When the limiting block 331 contacts the abutting end face, it slides into the receiving groove from the first guide slope 341, without the need for manual rotation of the movable rod 33.

[0057] Specifically, in actual use, the movable heat dissipation base plate 21 makes the limiting block 331 and the abutting end face in the same plane. Due to the presence of the second elastic element 35, there is a tendency for relative movement between the abutting end face and the limiting block 331. At this time, since the first guide slope 341 is formed on the abutting end face, a slight rotation of the movable rod 33 can make the limiting block 331 contact the first guide slope 341. Then, under the action of the second elastic element 35, the limiting block 331 slides from the first guide slope 341 into the receiving groove and rotates spontaneously without thermal rotation.

[0058] Furthermore, a second guide slope 342 is formed on the abutting end face, and the second guide slope 342 is inclined from the opening of the receiving groove toward the other edge of the abutting end face. When it is necessary to adjust to the second stop position, the drive heat dissipation base plate 21 is moved, so that the limiting block 331 is dislodged from the receiving groove and is on the same plane as the abutting end face. At this time, since the second guide slope 342 is formed at the opening of the receiving groove, a slight rotation of the movable rod 33 can make the limiting block 331 contact the second guide slope 342, and then, under the action of the second elastic member 35, slide and rotate along the second guide slope 342, and rotate into the space between two adjacent locking teeth blocks 34.

[0059] Furthermore, the limiting block 331 is provided with a mating inclined surface corresponding to the first guide inclined surface 341, so as to facilitate rotation with the first guide inclined surface 341.

[0060] Similarly, the aforementioned movable rod 33, limiting block 331, locking tooth block 34, second through hole, and second elastic element 35 together form an adjustment group, and multiple adjustment groups are provided to facilitate stable adjustment.

[0061] In the second embodiment described above, the specific implementation steps are as follows:

[0062] Under the action of the second elastic element 35, the limiting block 331 is positioned between two adjacent locking teeth 34 and remains in the second stop position;

[0063] When the stop position needs to be switched, the heat dissipation base plate 21 is manually driven to move, so that the limiting block 331 disengages from between the two locking blocks 34 and is flush with the abutting end face of the locking blocks 34. Under the spring torque and slight mechanical shaking, the mating inclined surface on the limiting block 331 contacts the first guide inclined surface on the abutting end face. Under the action of the second elastic element 35, the limiting block 331 moves relative to the abutting end face, so that the limiting block 331 slides from the first guide inclined surface into the receiving groove and reaches the first stop position, completing the automatic rotation. Under the action of the second elastic element 35, the limiting block 331 is kept in the receiving groove, so that the heat dissipation base plate 2 is kept in the first stop position.

[0064] When it is necessary to return to the second stop position, the heat dissipation base plate 21 is manually driven to move, so that the limiting block 331 is disengaged from the receiving groove and is flush with the abutting end face of the locking tooth block 34. Under the spring torque and slight mechanical shaking, the mating inclined surface on the limiting block 331 contacts the second guide inclined surface 342 on the abutting end face, slides along the second guide inclined surface into the space between the two locking tooth blocks 34, and returns to the second stop position.

[0065] The above structure allows the position of the heat dissipation base plate 21 to be switched by pressing, which is simple to operate and requires minimal manual intervention.

[0066] On the other hand, in order to improve heat dissipation efficiency, multiple heat dissipation grooves are recessed on the heat dissipation fins 22.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
