Description

Technical Field

[0001] The utility model relates to the technical field of silica gel gaskets, in particular to an easily adherable heat-conducting silica gel gasket. Background Art

[0002] A heat-conducting silica gel sheet is a heat-conducting medium material, which can reduce the contact thermal resistance generated between the surface of a heat source and the contact surface of a heat dissipation device. The heat-conducting silica gel sheet can well fill the gap of the contact surface. The heat-conducting silica gel gasket has the characteristics of high temperature resistance, heat conduction, flame retardancy, insulation, filling, etc., and is mainly used in the fields of power appliances, LED lamps, electronic equipment, etc. The existing silica gel gaskets are installed between the heat source and the radiator for heat conduction. However, in actual use, for a heat source with a larger size, it is difficult for a silica gel gasket with a fixed size to be completely adhered for heat conduction, and using multiple silica gel gaskets will result in waste, which limits the application range of the silica gel gasket, affects the actual heat conduction effect, and further reduces the practicability of the heat-conducting silica gel gasket, making it difficult to meet the actual use requirements. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an easily adherable heat-conducting silica gel gasket, which solves the problem that it is difficult for the prior art to be completely adhered to a heat source with a larger size, and using multiple silica gel gaskets will result in waste, thus limiting its application range.

[0004] To solve the above technical problems, the utility model provides the following technical solution: An easily adherable heat-conducting silica gel gasket includes a gasket main body, silica gel pads are respectively arranged around the gasket main body, a connecting component for connecting the four silica gel pads is arranged on the gasket main body, and an adhesion component for adhering to the heat source is arranged between two of the silica gel pads;

[0005] The connecting component includes connecting strips fixedly arranged around the gasket main body, and adjusting gaskets respectively arranged on one side of the four silica gel pads. Connecting blocks are fixedly arranged at both ends of the bottom of the adjusting gasket, and a positioning seat rotatably connected to the connecting strip is fixedly arranged on the adjusting gasket.

[0006] Further, square grooves matching the connecting blocks are respectively opened at both ends of one side of the silica gel pad, and a limiting shaft fixedly connected to the silica gel pad is rotatably arranged at the axis center of the connecting block.

[0007] Further, the adhesion component includes limiting grooves respectively opened at the bottoms of the mutually approaching ends of two silica gel pads, and square sheets respectively arranged inside the two limiting grooves, and the two square sheets are fixedly adhered to the corresponding silica gel pads respectively.

[0008] Further, vertical grooves are provided at one end of each of the two silicone pads close to each other. A connecting adhesive sheet is fixedly arranged between the two square sheets, and both sides of the connecting adhesive sheet are respectively matched with the two vertical grooves.

[0009] Further, a silicone bottom sheet is fixedly bonded to the bottom of the gasket body.

[0010] The utility model provides an easy-to-fit heat-conducting silicone gasket. Compared with the prior art, the following beneficial effects are achieved:

[0011] 1. In the utility model, a connecting component is arranged to connect the gasket body and the four silicone pads. When conducting heat for a heat source with a relatively large size, the four silicone pads are respectively pulled in four directions. The silicone pads pull and adjust the gasket, and the size of the entire silicone gasket is adjusted to be adapted to the heat source, which is beneficial to adjusting the heat-conducting area of the silicone gasket to adapt to a heat source with a relatively large size, expanding the application range of the silicone gasket, improving the practicability of the heat-conducting silicone gasket, and avoiding the situation that it is difficult for the silicone gasket to completely fit a heat source with a relatively large size, and multiple silicone gaskets are not used up.

[0012] 2. In the utility model, an adhesion component is arranged to paste the four silicone pads on the heat source simultaneously. When the four silicone pads move in four directions respectively, the square sheets and the connecting adhesive sheet move synchronously with the silicone pads. The square sheets between the two silicone pads move in perpendicular directions respectively, so as to stretch the connecting adhesive sheet to the horizontal direction. After the silicone pads stop moving, the connecting adhesive sheet is pressed on the heat source, making the silicone gasket fit more stably on the heat source, and the fitting operation is more convenient for use.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The heat-conducting silicone gasket has the advantages of soft material, good compression performance, good heat-conducting and insulating performance, a relatively large adjustable range of thickness, being suitable for filling cavities, having natural adhesiveness on both sides, strong operability and maintainability, and being used between the contact surfaces of the heat source surface and the heat dissipation device, which can make the contact surface between the heat source and the radiator better fully contact, truly achieving face-to-face contact. The temperature response can achieve a minimum temperature difference.

[0023] Please refer to Figure 1 - Figure 4 , the present invention provides an easily attachable heat-conducting silicone gasket, which includes a gasket main body 1. Silicone pads 2 are respectively arranged around the gasket main body 1. A connecting component 3 for connecting the four silicone pads 2 is arranged on the gasket main body 1. An adhesion component 4 for attaching to the heat source is arranged between two silicone pads 2. A silicone bottom sheet 5 is fixedly bonded to the bottom of the gasket main body 1. The bottom of the silicone bottom sheet 5 can be coated with heat-conducting silicone grease, which can enhance the heat conductivity of the entire silicone gasket.

[0024] The connecting component 3 includes connecting strips 31 fixedly arranged around the gasket main body 1, and adjusting gaskets 32 respectively arranged on one side of the four silicone pads 2. Connecting blocks 33 are fixedly arranged at both ends of the bottom of the adjusting gasket 32. Square grooves 34 matching the connecting blocks 33 are respectively opened at both ends of one side of the silicone pad 2. A limiting shaft 35 fixed to the silicone pad 2 is rotatably arranged at the center of the connecting block 33. A positioning seat 36 rotatably connected to the connecting strip 31 is fixedly arranged on the adjusting gasket 32.

[0025] Connect the connecting component 3 to connect the gasket body 1 and the four silicone pads 2. When conducting heat transfer for a heat source with a larger size, pull the four silicone pads 2 in four directions respectively. The silicone pads 2 drive the adjusting gasket 32 to move through the connecting seat. Both sides of the adjusting gasket 32 are rotatably connected to the silicone pads 2 and the gasket body 1 through the connecting blocks 33 and the connecting strips 31 respectively. The inclination angle of the adjusting gasket 32 gradually decreases, so that the adjusting gasket 32 unfolds and fits on the surface of the adapted heat source. When installing the radiator, the contact surface of the heat dissipation device fits on the top of the gasket body 1. At the same time, the gasket body 1 and the adjusting gasket 32 have a certain elasticity. The heat dissipation device presses the gasket body 1, so that the adjusting gasket 32 and the silicone negative film 5 both fit on the surface of the heat source, and the contact surface of the heat dissipation device can be kept flat.

[0026] As Figure 4 shown, specifically, the adhesion component 4 includes a limiting groove 41 opened at the bottom of the mutually approaching ends of the two silicone pads 2, and square pieces 42 respectively arranged inside the two limiting grooves 41. The two square pieces 42 are fixedly bonded to the corresponding silicone pads 2 respectively. Vertical grooves are opened at the mutually approaching ends of the two silicone pads 2. A connecting adhesive sheet 43 is fixedly arranged in the middle of the two square pieces 42, and both sides of the connecting adhesive sheet 43 match the two vertical grooves respectively.

[0027] When the four silicone pads 2 move in four directions respectively, the square pieces 42 and the connecting adhesive sheet 43 move synchronously with the silicone pads 2. The square pieces 42 between the two silicone pads 2 move in perpendicular directions respectively, so as to stretch the connecting adhesive sheet 43 to the horizontal direction. After the silicone pads 2 stop moving, press the connecting adhesive sheet 43 on the heat source, so that the silicone gasket fits on the heat source more stably.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
