Description

Technical Field

[0001] This utility model relates to the field of thermally conductive silicone pad technology, specifically to a puncture-resistant and highly reliable thermally conductive silicone pad. Background Technology

[0002] Thermally conductive silicone pads are thermally conductive media materials synthesized through a special process using silicone as the base material and adding auxiliary materials such as metal oxides. Their main function is to fill the gap between the heat-generating element and the heat-dissipating device, reducing contact thermal resistance and improving heat transfer efficiency. Thermally conductive silicone pads are widely used in electronics, automotive machinery, LED lighting, and other fields.

[0003] Existing thermal conductive silicone pads are mostly a mixture of silicone and metal materials, with a copper plate covering the surface of the silicone pad to improve puncture resistance. However, this method affects the heat dissipation of the silicone pad itself, and the copper plate is difficult to buffer external impacts, so the impact force will still be transmitted to the silicone pad. Utility Model Content

[0004] The purpose of this invention is to provide a highly reliable, puncture-resistant thermally conductive silicone sheet to solve the above-mentioned problems. The outer surface of the silicone sheet is covered by a connecting plate and a heat dissipation mechanism, both of which have an arc-shaped appearance, thereby improving the protection performance against external punctures. At the same time, the conduction mechanism improves the tightness of the connection between the silicone sheet and the heat dissipation mechanism, thereby increasing the heat transfer efficiency and the heat dissipation speed.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A puncture-resistant, highly reliable thermally conductive silicone sheet includes: a silicone plate, an extension layer fixedly disposed between the silicone plates, connecting bolts threaded around the top side of each silicone plate, a fixing plate fixedly disposed between each pair of the four connecting bolts, multiple connecting plates horizontally disposed between the two fixing plates, multiple heat dissipation mechanisms fixedly disposed between each pair of the multiple connecting plates, and a first connecting mechanism and a second connecting mechanism horizontally penetrating the inner side of each of the multiple heat dissipation mechanisms.

[0007] The plurality of heat dissipation mechanisms include a first arc-shaped plate and a second arc-shaped plate, and a through groove is provided in the middle of one side of both the first arc-shaped plate and the second arc-shaped plate.

[0008] Furthermore, both the first and second arc-shaped plates are made of copper, and the first and second arc-shaped plates are symmetrically arranged and present an overall S-shape.

[0009] Furthermore, each of the first connecting mechanisms includes a limiting plate, a first inclined plate is fixedly disposed on the top side of the limiting plate, and a first through plate is fixedly disposed on one side of the limiting plate near the top.

[0010] Furthermore, a heat dissipation slide plate is fixedly installed on one side of the first through plate, and telescopic connecting strips are fixedly installed on both the front and rear sides of the heat dissipation slide plate on one side of the first through plate. Multiple heat dissipation holes are opened through the top side of the heat dissipation slide plate.

[0011] Furthermore, each of the second connecting mechanisms includes a limiting inclined plate, a second through plate is fixedly provided on one side of the limiting inclined plate, and a slotted plate is fixedly provided on one side of the second through plate.

[0012] Furthermore, a transverse sliding groove is provided in the middle of one side of the slotted plate, and connecting grooves are provided on both the front and rear sides of the transverse sliding groove in the middle of one side of the slotted plate. The second through plate is located at the included angle inside the limiting inclined plate.

[0013] Furthermore, one side of the telescopic connecting strip is fixedly connected to the first through plate, and the other side is fixedly connected to the inner side of the slotted plate.

[0014] Furthermore, the size of the opening of the transverse groove is the same as that of the heat dissipation slide plate.

[0015] Furthermore, a conduction mechanism is fixedly provided on both the front and rear sides of the silicone plate, and the conduction mechanism includes a Z-shaped sliding plate.

[0016] Furthermore, clamping triangular plates are fixedly installed on both sides of the rear side of the Z-shaped slide plate, and the two clamping triangular plates are installed on both sides of one of the multiple connecting plates.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-6As shown, this utility model provides a puncture-resistant, highly reliable thermally conductive silicone sheet, comprising: a silicone plate 1, an extension layer 2 fixedly disposed between the silicone plates 1, connecting bolts 3 threaded around the top side of the silicone plate 1, a fixing plate 4 fixedly disposed between each pair of the four connecting bolts 3, a plurality of connecting plates 5 horizontally disposed between the two fixing plates 4, a plurality of heat dissipation mechanisms 6 fixedly disposed between each pair of the plurality of connecting plates 5, and a first connecting mechanism 7 and a second connecting mechanism 8 horizontally penetrating the inner side of each of the plurality of heat dissipation mechanisms 6;

[0033] Using the above technical solution, the extension layer 2 between the silicone plates 1 increases the area covered by the silicone plates 1 during installation by stretching. At this time, the extension layer 2 will extend outward by a certain distance. When the electronic components are not in use, the silicone plates 1 will shrink according to their own characteristics. At the same time, the stretched silicone plates 1 will increase the area covered by the electronic components. When the electronic components are turned on, heat is generated, and the extension layer expands due to heat, pushing the silicone plates 1 and stretching the heat dissipation mechanism 6. When the heat dissipation mechanism 6 is stretched, the contact area between the silicone plates 1 and the air is increased through the first connecting mechanism 7 and the second connecting mechanism 8 on the inner side, thereby improving the heat dissipation efficiency. The arc design of the connecting plate 5 can buffer the impact force and prevent the silicone plates 1 from being punctured due to direct force. The arc design of the connecting plate 5 also increases the contact area with the air.

[0034] See Figures 5-6 As shown, the multiple heat dissipation mechanisms 6 include a first arc-shaped plate 601 and a second arc-shaped plate 602. A through groove 603 is provided in the middle of one side of both the first arc-shaped plate 601 and the second arc-shaped plate 602. The first arc-shaped plate 601 and the second arc-shaped plate 602 are both made of copper. The first arc-shaped plate 601 and the second arc-shaped plate 602 are symmetrically arranged and have an overall S-shape.

[0035] In use, the symmetrical arrangement of the first arc-shaped plate 601 and the second arc-shaped plate 602 in the heat dissipation mechanism 6, and the connection plates 5 on both sides of the heat dissipation mechanism 6 respectively, causes the arc-shaped plates connected to them to be pulled together when the position of the connection plate 5 changes. At this time, the first arc-shaped plate and the second arc-shaped plate 602 are spread out, directly increasing the contact area between the silicone plate 1 and the air outside the heat dissipation mechanism 6, thereby increasing the heat dissipation efficiency. The first arc-shaped plate 601 and the second arc-shaped plate 602 are symmetrical and S-shaped. When subjected to external impact force, the arc buffers these impact forces, preventing the impact force from directly acting on the silicone plate 1 and improving the safety against puncture.

[0036] See Figures 6-9As shown, each of the multiple first connecting mechanisms 7 includes a limiting plate 701. A first inclined plate 702 is fixedly disposed on the top side of the limiting plate 701. A first through plate 703 is fixedly disposed on one side of the limiting plate 701. A heat dissipation slide plate 705 is fixedly disposed on one side of the first through plate 703. Telescopic connecting strips 704 are fixedly disposed on both the front and rear sides of the heat dissipation slide plate 705 on one side of the first through plate 703. A plurality of heat dissipation holes 706 are opened through the top side of the heat dissipation slide plate 705. One side of the telescopic connecting strip 704 is fixedly connected to the first through plate 703, and the other side is fixedly connected to the inner side of the slotted plate 803.

[0037] In the above embodiment, the arc-shaped plate in the heat dissipation mechanism 6 is closely attached to the limiting plate 701 and the first inclined plate 702, and the first inclined plate 702 directly forms an arc surface with the arc-shaped plate, which improves the buffering of impact force. The first through plate 703 on one side of the limiting plate 701 and the telescopic connecting strips 704 on the front and back of one side form a connection with the second connecting mechanism 8. At the same time, the heat dissipation plate 705 fixed between the two telescopic connecting strips 704 and the multiple heat dissipation holes 706 opened in the heat dissipation plate 705 improves the heat dissipation efficiency of the first connecting mechanism 7. At the same time, after the limiting plate 701 and the first inclined plate 702 come into contact with the arc-shaped plate, since high temperature always flows to low temperature, the temperature will flow through the limiting plate 701 and the first inclined plate 702 to the heat dissipation plate 705 and be dissipated through the heat dissipation holes 706, thereby improving the overall heat dissipation efficiency.

[0038] See Figures 6-9 As shown, each of the multiple second connecting mechanisms 8 includes a limiting inclined plate 801. A second through plate 802 is fixedly provided on one side of the limiting inclined plate 801. A slotted plate 803 is fixedly provided on one side of the second through plate 802. A transverse sliding groove 804 is provided in the middle of one side of the slotted plate 803. Connecting grooves 805 are provided on both the front and rear sides of the transverse sliding groove 804 in the middle of one side of the slotted plate 803. The second through plate 802 is located at the included angle inside the limiting inclined plate 801. The size of the opening of the transverse sliding groove 804 is the same as that of the heat dissipation slide plate 705.

[0039] In use, heat is transferred through contact between the limiting inclined plate 801 and one of the arc-shaped plates in the heat dissipation mechanism 6. The second through plate 802 is inserted into the through slot 603 of one of the arc-shaped plates to form the installation of the second connecting mechanism 8. The connecting slots 805 on the front and back of the slotted plate 803 on one side of the second through plate 802 and the transverse sliding groove 804 between the two connecting slots 805 are connected to the first connecting mechanism 7. The connecting slots 805 are connected to the telescopic connecting strip 704. The transverse sliding groove 804 provides a space for the heat dissipation plate 705. After the heat dissipation mechanism 6 is heated and expanded by the silicone plate 1 and the extension layer, the heat dissipation plate 705 and the heat dissipation holes 706 on the surface are exposed to the outside, which further improves the heat dissipation efficiency of the silicone plate 1.

[0040] See Figure 2 and Figure 3 As shown, a transmission mechanism 9 is fixedly provided on both the front and rear sides of the silicone plate 1. The transmission mechanism 9 includes a Z-shaped sliding plate 901. Clamping triangular plates 902 are fixedly provided on both sides of the rear side of the Z-shaped sliding plate 901. The two clamping triangular plates 902 are provided on both sides of one of the multiple connecting plates 5.

[0041] Specifically, the Z-shaped sliding plate 901 and the outer side of the silicone plate 1 are snapped together, and two clamping triangular plates 902 are set on both sides of the arc surface of the connecting plate 5, so that the conduction mechanism 9 is connected to the connecting plate 5 as a whole. The heat of the silicone plate 1 is transferred through the Z-shaped sliding plate 901 and then through the clamping triangular plates 902. The clamping triangular plates 902 complete the connection and the heat transfer at the same time.

[0042] Using the above structure, during installation, the product is stretched and then pasted, causing the silicone plate 1 to extend to a certain extent. Before being heated, it shrinks according to the properties of silicone itself, adhering tightly to the electronic product requiring heat dissipation. When the electronic product is turned on, the silicone plate 1 is heated and undergoes thermal expansion and contraction. At this time, the extended layer at the point where the silicone plate 1 was stretched and pasted will be stretched to the width of the silicone plate 1 after stretching. At this time, the fixing plates 4 on both sides above the silicone plate 1 will pull the multiple connecting plates 5 on the inside to both sides. After the multiple connecting plates 5 are stretched, they will pull apart the heat dissipation mechanisms 6 between each pair. When the heat dissipation mechanisms 6 are pulled apart, the first arc-shaped plate 601 and the second arc-shaped plate 602 symmetrically arranged in the heat dissipation mechanism 6 will release heat. The first arc-shaped plate 601 and the limiting plate 701 and the first inclined plate 702 in the first connecting mechanism 7 are in contact, and the second arc-shaped plate 602 and the limiting inclined plate 801 in the second connecting mechanism 8 are in contact, so that the distance between the limiting plate 701 and the limiting inclined plate 801 is increased. At this time, the first through plate 703 on one side of the limiting plate 701 and the heat dissipation slide plate 705 on one side slide out from the transverse slide groove 804 in the second connecting mechanism 8. At this time, the heat dissipation mechanism 6 is in a separated state, and the first connecting mechanism 7 and the second connecting mechanism 8 are not separated, providing space for the lower silicone plate 1 extension layer to contact with the air. Furthermore, the connecting plate 5, the heat dissipation mechanism 6, the first connecting mechanism 7 and the second connecting mechanism 8 are all made of copper, which, together with the silicone plate 1, increases the contact area with the air, thereby improving the heat dissipation effect of this product.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
