Description

Technical Field

[0001] The present application relates to the technical field of silicone gaskets, and more specifically, to a pressure-resistant silicone thermally conductive gasket. Background Art

[0002] Thermal conductive silicone gaskets are based on silicon dioxide and are added with alumina in a certain proportion according to different needs. In the industry, they are also called thermal conductive silicone sheets, thermal conductive insulation sheets, thermal conductive silicone sheets, soft thermal pads, etc. They are specially designed for transferring heat through gaps. They can fill the gaps and complete the heat transfer between the heating part and the heat dissipation part. At the same time, they also play the role of insulation, shock absorption, and sealing.

[0003] According to the search, the Chinese patent with the announcement number CN218831040U discloses a pressure-resistant thermally conductive silicone gasket, which includes a first silicon pad, two silicon plates are symmetrically installed on the bottom of the first silicon pad, and a second silicon pad is installed on the side of one end of the two silicon plates away from the first silicon pad. Heat conduction holes are provided on one side of the surface wall of the first silicon pad and the second silicon pad, diamond sheets are provided around the first silicon pad and the second silicon pad, and slots are provided on one side of the surface wall of the first silicon pad and the second silicon pad. The utility model is provided with a first silicon pad and a second silicon pad, and a connected silicon plate is provided between the two silicon pads, which improves the continuity of heat dissipation. The diamond sheet can improve the overall rigidity of the side wall of the composite gasket, ensuring that it will not collapse under the pressure of heavy objects, thereby ensuring the heat dissipation capacity under different usage environments.

[0004] Regarding the above-mentioned related technologies, the applicant believes that although they can prevent the silicone gasket from deforming and affecting the thermal conductivity, the hardness of the diamond sheet is too high. When the heat-conducting object applies pressure to it, it may cause damage to the heat-conducting object. For this reason, we propose a pressure-resistant silicone thermal conductive gasket.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4 A pressure-resistant silicone thermal gasket includes a main body module 100 and a pressure-resistant module 200. The main body module 100 includes a first silicone gasket 110. A second silicone gasket 120 is arranged below the first silicone gasket 110. The pressure-resistant module 200 is arranged between the first silicone gasket 110 and the second silicone gasket 120. The pressure-resistant module 200 includes a first pressure-resistant component 210 arranged between the inside of the first silicone gasket 110 and the second silicone gasket 120, and a second pressure-resistant component 220 is arranged between the surfaces of the first silicone gasket 110 and the second silicone gasket 120.

[0038] By setting the first pressure-resistant component 210, the first silicone gasket 110 and the second silicone gasket 120 can be connected into a whole. At the same time, the first pressure-resistant component 210 can maintain the state of the first silicone gasket 110 and the second silicone gasket 120 according to the degree of pressure. By setting the second pressure-resistant component 220, the rebound ability of the first silicone gasket 110 and the second silicone gasket 120 can be improved, so that the gasket can avoid deformation of the gasket and affect the thermal conductivity without damaging the pressure-applying object.

[0039] The first pressure-resistant component 210 includes a plurality of placement grooves 211 respectively opened between the first silicone gasket 110 and the second silicone gasket 120, and a silicone sleeve 212 is inserted into the interior of the plurality of placement grooves 211, and a reset spring 213 is provided inside the plurality of silicone sleeves 212. The first pressure-resistant component 210 also includes a plurality of first glue layers 214 respectively coated on the surfaces of the plurality of silicone sleeves 212, and the plurality of silicone sleeves 212 are respectively bonded and connected to the interior of the plurality of placement grooves 211 through the plurality of first glue layers 214. The second pressure-resistant component 220 includes a plurality of groups of sleeve blocks 221 respectively arranged between the surfaces of the first silicone gasket 110 and the second silicone gasket 120, and an insert block 222 is movably inserted into the interior of each group of sleeve blocks 221. The second pressure-resistant component 220 also includes a plurality of rebound rubber strips 223 respectively fixedly connected to the plurality of groups of insert blocks 222, and the material of the rebound rubber strips 223 is silicone.

[0040] When the gasket is subjected to pressure, the pressure-applying object will drive the return spring 213 to contract through the silicone sleeve 212, and at the same time drive the rebound rubber strip 223 to close. The pressure of the return spring 213 will maintain the state of the gasket through the silicone sleeve 212. At the same time, the rebound rubber strip 223 can also make the gasket have better rebound ability, so that the gasket can avoid deformation of the gasket and affect the thermal conductivity without damaging the pressure-applying object.

[0041] The main module 100 also includes two adhesive components 130 respectively arranged on the top of the first silicone gasket 110 and the bottom of the second silicone gasket 120. The adhesive component 130 includes a second glue layer 131 coated on the top of the first silicone gasket 110 and the bottom of the second silicone gasket 120. The two second glue layers 131 are both covered with dustproof stickers 132, and the two dustproof stickers 132 are both provided with raised stickers 133.

[0042] The dustproof sticker 132 is torn off through the raised sticker 133 , and then the second glue layer 131 is applied to the object to be installed, so that the second glue layer 131 can adhere to the object to be installed, thereby installing the gasket.

[0043] The implementation principle of the embodiment of the present application is as follows: when working, the dustproof sticker 132 can be torn off through the raised sticker 133, and then the gasket can be attached to the position where it needs to be installed through the second glue layer 131. When the gasket is subjected to pressure, the pressure-applying object will drive the return spring 213 to contract through the silicone sleeve 212. Since the surface of the silicone sleeve 212 is adhered to the inner wall of the placement groove 211 through the first glue layer 214, the return spring 213 can keep the first silicone gasket 110 and the second silicone gasket 120 from being drastically deformed according to the degree of pressure, and at the same time can avoid damage to the pressure-applying object by excessive hardness. When the gasket is subjected to pressure, the pressure-applying object will also apply pressure to the rebound rubber strip 223, but the rebound rubber strip 223 is made of silicone and has good rebound performance, which can further maintain the state of the first silicone gasket 110 and the second silicone gasket 120, so that the gasket can avoid deformation of the gasket and affect the thermal conductivity without damaging the pressure-applying object.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
