Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to a diamond composite heat sink device. Background Art

[0002] Due to the rapid development of integrated circuits and electronic devices, new packaging forms are constantly emerging. At present, the packaging shells of high-power electronic devices usually use heat sink materials, mainly tungsten-copper alloys, molybdenum-copper alloys, CPC, CMC, Kovar alloys and other high thermal conductivity heat sink materials. However, in high-power electronic devices, the thermal conductivity of the heat sink material in the thickness direction, referred to as the Z-direction thermal conductivity, is required to be higher. Single-filament traditional heat sink materials can no longer meet the requirements of efficient heat dissipation. Metal-based diamond composites have become the most promising new generation of heat sink materials with their high thermal conductivity and low thermal expansion coefficient. However, the weldability and electroplating performance of metal-based diamond composites are relatively poor, and cannot meet the use of later packaging.

[0003] For example, a Chinese utility model patent (CN212786456U) discloses a diamond composite heat sink device, which records: "Through a combined structure, the heat sink frame and the heat sink are combined into a whole. The structure can make the heat sink of the composite diamond composite material directly contact with the electronic device, thereby improving the heat dissipation efficiency." It also records: "The sandwich packaging form commonly used in the prior art isolates the diamond-based composite material from direct contact with the electronic device, and the sheet or block packaging form seriously affects its Z-direction heat dissipation efficiency and cannot meet the use requirements of high-power electronic devices." Technical problems.

[0004] Based on the above, it can be seen that the following technical problems exist in the prior art: in the above patent, the heat dissipation efficiency is improved by plugging and fixing the frame and the heat sink into a whole. However, during the processing of the frame and the heat sink, although they look very smooth, there are still some irregularities and bumps at the microscopic level, which makes a small gap between the radiator and the frame, thereby affecting the heat conduction efficiency of the device. For this reason, the present application proposes a diamond composite heat sink device to provide a new technical solution to solve the technical problems mentioned in the above patent.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] As described in the background technology, the above patent improves the heat dissipation efficiency by plugging and fixing the frame and the heat sink into a whole. However, during the processing of the frame and the heat sink, although they look very smooth, there are still some irregularities and bumps at the microscopic level, which makes a small gap between the radiator and the frame, thereby affecting the heat conduction efficiency of the device.

[0030] In order to solve this technical problem, the utility model provides a diamond composite heat sink device, which is used for heat conduction and heat dissipation.

[0031] Specifically, please refer to Figure 1-Figure 7 , the diamond composite heat sink device specifically includes:

[0032] A diamond-based composite heat sink 1, a fixing mechanism 2 and a wind heat dissipation mechanism 3. A fixing mechanism 2 for fixing the diamond-based composite heat sink 1 is provided below the diamond-based composite heat sink 1, and a wind heat dissipation mechanism 3 for improving the heat exchange efficiency between the diamond-based composite heat sink 1 and the air is provided above the diamond-based composite heat sink 1;

[0033] The fixing mechanism 2 includes a mounting groove 4, a first frame 5, a second frame 6, a clamping assembly and a heat conducting assembly. There are two first frames 5 and they are symmetrically arranged. A plurality of second frames 6 are equidistantly arranged between the two first frames 5. The surfaces of the first frame 5 and the second frame 6 are both provided with mounting grooves 4, and the diamond-based composite material heat sink 1 extends to the inner side of the mounting groove 4.

[0034] The diamond composite heat sink device provided by the utility model can, through the structural design of the fixing mechanism 2, clamp and fix the diamond-based composite heat sink 1 by turning the knob 10 after the diamond-based composite heat sink 1 is inserted into the inner side of the installation groove 4. The tiny gap generated when the diamond-based composite heat sink 1 is installed can be reduced and filled by clamping and the silicone thermal pad 11, thereby effectively improving the heat conduction efficiency of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 1-Figure 4 A diamond composite heat sink device comprises: a diamond-based composite heat sink 1, a fixing mechanism 2 and a wind heat dissipation mechanism 3, wherein the fixing mechanism 2 for fixing the diamond-based composite heat sink 1 is arranged below the diamond-based composite heat sink 1, and the wind heat dissipation mechanism 3 for improving the heat exchange efficiency between the diamond-based composite heat sink 1 and the air is arranged above the diamond-based composite heat sink 1;

[0038] Specifically, the fixing mechanism 2 includes a mounting groove 4, a first frame 5, a second frame 6, a clamping assembly and a heat conducting assembly. The number of first frames 5 is two and they are symmetrically arranged. A plurality of second frames 6 are equidistantly arranged between the two first frames 5. The surfaces of the first frame 5 and the second frame 6 are both provided with mounting grooves 4, and the diamond-based composite material heat sink 1 extends to the inner side of the mounting groove 4.

[0039] Furthermore, the clamping assembly includes a threaded rod 8, a fixed baffle 9 and a knob 10. There are two threaded rods 8 and they are symmetrically arranged at the two end positions of the first frame 5 and the second frame 6. The two threaded rods 8 both penetrate the ends of the first frame 5 and the second frame 6 and extend outward. The first frame 5 and the second frame 6 are both movably connected to the threaded rod 8. One end of the threaded rod 8 is fixedly connected to the fixed baffle 9, and the end of the threaded rod 8 away from the fixed baffle 9 is threadedly connected to the knob 10. The fixed baffle 9 and the knob 10 are tightly fitted with the two first frames 5 respectively.

[0040] Furthermore, the heat-conducting component includes a silicone thermal pad 11 , which is fixedly connected to the inner side of the mounting groove 4 , and the surface of the silicone thermal pad 11 is tightly fitted to the diamond-based composite material heat sink 1 .

[0041] It can be seen that after the diamond-based composite heat sink 1 is placed inside the mounting groove 4, the knob 10 can be rotated. While the knob 10 is rotating, the distance between the fixed baffle 9 and the knob 10 will gradually decrease, so that the fixed baffle 9 and the knob 10 respectively push the two first frames 5 to gradually move towards each other. While the two first frames 5 move, they will push the diamond-based composite heat sink 1 and the second frame 6 to move, thereby clamping and fixing the diamond-based composite heat sink 1 inside the mounting groove 4. While clamping the diamond-based composite heat sink 1, the silicone thermal pad 11 inside the mounting groove 4 will further fill the gaps between the first frame 5 and the diamond-based composite heat sink 1 and between the second frame 6 and the first frame 5, thereby improving the thermal conduction efficiency of the device.

[0042] Furthermore, the surface of the diamond-based composite material heat sink 1 is evenly provided with heat dissipation grooves 7 , which can facilitate air flow and reduce the material cost of the diamond-based composite material heat sink 1 .

[0043] Embodiment 2:

[0044] The diamond composite heat sink device provided in Example 1 is further optimized. Specifically, Figure 5-Figure 7 As shown, further, the wind heat dissipation mechanism 3 includes a mounting plate 14, a fan 15 and a connecting component. The mounting plate 14 is arranged above the diamond-based composite heat sink 1. The mounting plate 14 is tightly fitted to the top surface of the diamond-based composite heat sink 1, and the fan 15 is embedded and fixedly connected in the middle of the mounting plate 14.

[0045] Furthermore, the connecting assembly includes a rotating seat 12, a connecting plate 13, a positioning groove 16, a clamping plate 17, a hand-tightening bolt 18 and a spring 19. The connecting plate 13 is rotatably connected to the top of the first frame 5 through the rotating seat 12. A positioning groove 16 is provided on the outer side of the mounting plate 14 and at a position corresponding to the connecting plate 13. The inside of the connecting plate 13 is slidably connected to the clamping plate 17. Both ends of the clamping plate 17 extend to the outer side of the connecting plate 13 and fit tightly with the surface of the mounting plate 14. A hand-tightening bolt 18 is provided above the clamping plate 17. The hand-tightening bolt 18 is threadedly connected to the connecting plate 13. A spring 19 is provided inside the connecting plate 13 and at a position below the clamping plate 17. Both ends of the spring 19 are fixedly connected to the connecting plate 13 and the clamping plate 17, respectively.

[0046] It can be seen that when in use, the air flow around the diamond-based composite heat sink 1 can be enhanced by starting the fan 15, so that the heat absorbed by the diamond-based composite heat sink 1 can be transferred to the air faster. When the mounting plate 14 and the fan 15 need to be disassembled or the surface of the diamond-based composite heat sink 1 needs to be cleaned, the hand-tightening bolt 18 can be rotated to disengage the hand-tightening bolt 18 from the clamping plate 17. The clamping plate 17 will move upward and separate from the mounting plate 14 under the push of the spring 19, and then the connecting plate 13 can be flipped outward to release the movement limit of the mounting plate 14.
