Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting silicone gaskets, in particular to a composite heat-conducting silicone gasket. Background Art

[0002] The composite heat-conducting silicone gasket is a high-performance gap-filling composite heat-conducting material, mainly used for the transfer interface between electronic devices and heat sinks or product casings. It has good viscosity, flexibility, good compression performance and excellent thermal conductivity, enabling the air between electronic components and heat sinks to be completely discharged during use to achieve full contact. The thickness range of the heat-conducting silicone sheet is generally between 0.5 mm and 3 mm. When selecting the thickness, the gap size between the heat source and the radiator needs to be considered. Usually, the thickness of the heat-conducting silicone sheet should be about 20% greater than the actual gap.

[0003] In the prior art, as disclosed in Chinese Patent CN219876643U, a composite heat-conducting silicone pad is provided, which includes a heat-conducting silicone gasket body and a splicing mechanism. The heat-conducting silicone gasket body is arranged inside the inner ring of the splicing mechanism. The heat-conducting silicone gasket body also includes an upper silicone gasket and a lower silicone gasket. A heat-conducting copper core arranged in a cross shape is placed between the upper silicone gasket and the lower silicone gasket, and the upper silicone gasket and the lower silicone gasket are adhesively bonded to each other. The splicing mechanism also includes a frame body and a clamping component. The clamping component is installed on the frame body, and it is convenient to splice with another frame body through the clamping component.

[0004] In the prior art, as in the above-mentioned patent, although it enables two skeletons to be quickly spliced together and conveniently disassembled, thus facilitating heat conduction for different types of electronic components, there are still the following drawbacks. As mentioned in the above patent, the size of the frame for fixing the silicone gasket is fixed. When using the silicone gasket, according to the heat conduction conditions of different components, a silicone gasket with a corresponding thickness is used to better conduct heat. If the silicone gasket is too thick or too thin, the silicone gasket cannot be fixed inside the frame or becomes loose inside the frame, resulting in the silicone gasket being unable to dissipate heat normally.

However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] As Figure 1 -5 shows, the present invention provides a composite heat-conducting silicone gasket, including a frame 1. Storage grooves 12 are provided at the upper ends of the four groups of frames 1 near the four corners. Fixed structures 2 are arranged inside the four groups of storage grooves 12. The fixed structure 2 includes a rotating rod 21. A rotating hole 22 is provided inside the storage groove 12. A pressure plate 24 is slidably installed on the outer wall of the rotating rod 21.

Connecting blocks 28 are fixedly installed on the outer wall of the pull rod 210, and there are two groups of connecting blocks 28. A pull handle 29 is fixedly installed at the upper end of the pull rod 210. The lower end of the support spring 26 is fixed to the upper end of the ring plate 27. The lower end of the ring plate 27 is fixed to the upper end of the pressure plate 24. The two groups of connecting blocks 28 respectively pass through the two groups of limiting holes 23 and are fixed to the inner wall of the ring plate 27. A placing groove 11 is provided at the upper end of the frame 1. The four groups of rotating rods 21 are respectively rotatably arranged with the four groups of rotating holes 22.

[0025] Specifically describe the specific settings and functions of this embodiment below. Rotate the pull handle 29, and the pull handle 29 drives the pull rod 210 fixed thereto to rotate together. Through the cooperation of the two groups of limit holes 23 and the two groups of connecting blocks 28, the two groups of limit holes 23 can respectively block the two groups of connecting blocks 28. The pull rod 210 can only drive the rotating rod 21 to rotate and move through the two groups of connecting blocks 28 fixed thereto, so that the rotating rod 21 rotates inside the rotating groove. At the same time, the two groups of connecting blocks 28 drive the pressing plate 24 to rotate together through the circular ring plate 27, so that the pressing plate 24 moves to directly above the silicone gasket, and under the elastic force of the support spring 26, the support spring 26 pushes the pressing plate 24 downward through the circular ring plate 27 fixed thereto. The circular ring plate 27 and the pressing plate 24 fixed thereto slide downward on the outer wall of the rotating rod 21 until the bottom end of the pressing plate 24 contacts the surface of the silicone gasket. Through the cooperation of the four groups of fixing structures 2, the silicone gasket can be pressed inside the placement groove 11, so as to fix the silicone gasket. At the same time, by pulling the pull handle 29 upward, the pull handle 29 will drive the pull rod 210 fixed thereto to move upward together, so that the pull rod 210 slides upward inside the rotating rod 21, and the pull rod 210 will drive the two groups of connecting blocks 28 fixed thereto to move, so that the two groups of connecting blocks 28 move upward inside the two groups of limit holes 23 respectively. The two groups of connecting blocks 28 will drive the circular ring plate 27 fixed thereto to move upward, and the circular ring plate 27 drives the pressing plate 24 to slide upward on the outer wall of the rotating rod 21 together, which can adjust the height inside the storage groove 12, facilitate placing silicone gaskets of different thicknesses into the storage groove 12, and cooperate with the above steps, so as to fix silicone gaskets of different thicknesses, prevent the silicone gasket from being unable to be fixed inside the frame 1 or being loose inside the frame 1, facilitate the normal heat dissipation of the silicone gasket. Secondly, the setting of the placement groove 11 facilitates placing the silicone gasket inside it for fixing it.

[0026] Embodiment Two

[0027] As Figure 1 and Figure 2 As shown, assembly structures 3 are provided at both ends of the frame 1. The assembly structure 3 includes a clamping block 31. A limit groove 32 is opened at the other end of the frame 1. Through holes 34 are respectively opened through the front and rear ends of the frame 1 and at the position of the limit groove 32. Threaded holes 33 are opened at the front and rear ends of the clamping block 31. Bolts 35 are respectively arranged inside the two groups of through holes 34. One end of the clamping block 31 is fixed to one end of the frame 1. The size of the clamping block 31 is the same as the size of the limit groove 32. The two groups of bolts 35 are respectively threadedly connected to the two groups of threaded holes 33.

[0028] The effect achieved by the entire embodiment is as follows: Pick up the other set of frames 1, insert the clamping blocks 31 of the other set of frames 1 into the limiting slots 32 of this frame 1. Push the two bolts 35 respectively, so that the two bolts 35 pass through the two through holes 34 to the screw openings of the two threaded holes 33. Then, screw the two bolts 35 clockwise one by one, so that the bolts 35 rotate inside the threaded holes 33 that match them. After the two bolts 35 are screwed in, the clamping blocks 31 are fixed inside the limiting slots 32, thereby enabling the assembly of the two frames 1 and achieving the function of quick splicing. Conversely, by screwing the two bolts 35, it is convenient to disassemble the two frames 1. In summary, it is convenient to conduct heat conduction for different types of electronic components.

[0029] The usage method and working principle of this device are as follows: First, place the silica gel gasket into the placement groove 11. By pulling the handle 29 upwards, the handle 29 will drive the fixed pull rod 210 to move upwards together, so that the pull rod 210 slides upwards inside the rotating rod 21. And the pull rod 210 will drive the two connecting blocks 28 fixed to it to move, so that the two connecting blocks 28 move upwards inside the two limiting holes 23 respectively. The two connecting blocks 28 will drive the ring plate 27 fixed to them to move upwards, and the ring plate 27 drives the pressing plate 24 to slide upwards on the outer wall of the rotating rod 21 together. Then, rotate the handle 29, and the handle 29 drives the fixed pull rod 210 to rotate together. With the cooperation of the two limiting holes 23 and the two connecting blocks 28, the two limiting holes 23 can respectively block the two connecting blocks 28. The pull rod 210 can only drive the rotating rod 21 to rotate and move through the two connecting blocks 28 fixed to it, so that the rotating rod 21 rotates inside the rotating groove. At the same time, the two connecting blocks 28 drive the pressing plate 24 to rotate together through the ring plate 27, so that the pressing plate 24 moves to directly above the silica gel gasket. Under the elastic force of the supporting spring 26, the supporting spring 26 pushes the pressing plate 24 downwards through the fixed ring plate 27. And the ring plate 27 and the pressing plate 24 fixed to it slide downwards on the outer wall of the rotating rod 21 together until the bottom end of the pressing plate 24 contacts the surface of the silica gel gasket. Through the cooperation of the four fixing structures 2, the silica gel gasket can be pressed inside the placement groove 11. Finally, according to the size of the electronic component, assemble several sets of frames 1. Pick up the other set of frames 1, insert the clamping blocks 31 of the other set of frames 1 into the limiting slots 32 of this frame 1. Push the two bolts 35 respectively, so that the two bolts 35 pass through the two through holes 34 to the screw openings of the two threaded holes 33. Then, screw the two bolts 35 clockwise one by one, so that the bolts 35 rotate inside the threaded holes 33 that match them. After the two bolts 35 are screwed in, the clamping blocks 31 are fixed inside the limiting slots 32, and the two frames 1 can be assembled. Repeat the assembly steps until the size of the assembled frame 1 is the same as the size of the electronic component.
