Description

Technical Field

[0001] The utility model relates to the technical field of thermally conductive gels, in particular to a low-hardness and high-thermal conductive gel. Background Art

[0002] Thermally conductive gel is a material with good thermal conductivity, usually used for heat dissipation and heat conduction. It can be filled in the heat dissipation module of electronic equipment or computers to help effectively conduct heat and prevent the equipment from overheating and damage. Thermally conductive gel usually has good adhesion and can firmly adhere between the heat dissipation component and the heat dissipation plate to improve the heat dissipation effect. However, some thermally conductive gels with higher hardness are not soft enough and have a certain plasticity, so that they cannot completely fill the tiny gaps or uneven surfaces between the heat dissipation components, resulting in increased thermal resistance and reduced heat conduction efficiency, which in turn affects the heat dissipation effect, causing the equipment to overheat and reduce its service life.

[0015] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] It should be noted that the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0021] like Figure 1-3As shown, the utility model provides a low-hardness and high-thermal-conductivity gel, comprising a thermally conductive gel central body 1, and also comprising: a mesh structure 11 provided in the thermally conductive gel central body 1 for filling the gaps between irregular surfaces and increasing the contact area, wherein the mesh structure 11 can fill the gaps between irregular surfaces, increase the contact area, and improve the heat conduction efficiency; a first adhesive layer 4 and a second adhesive layer 5 adhered to the upper and lower surfaces of the thermally conductive gel central body 1, wherein the thickness of the first adhesive layer 4 is 0.2 mm-15 mm, and the thickness of the second adhesive layer 5 is 0.15 mm-0.2 mm, wherein the first adhesive layer 4 is connected to the second silicone elastic layer 3 on one side away from the thermally conductive gel central body 1, and the second adhesive layer 5 is connected to the first silicone elastic layer 2 on one side away from the thermally conductive gel central body 1, and a plurality of linearly arranged infiltration protrusions 21 are provided on one side of the second silicone elastic layer 3 close to the first adhesive layer 4 and on one side of the first silicone elastic layer 2 close to the second adhesive layer 5, wherein the infiltration protrusions 21 can increase the adhesion, thereby achieving a tighter fit. The infiltration protrusions 21 are cylindrical in structure and are provided in multiple groups. The multiple groups of infiltration protrusions 21 are distributed at equal distances and in equal sizes. The material of the first silicone elastic layer 2 and the second silicone elastic layer 3 is silicone, and silicone is an elastomeric material with good softness and deformation ability, which can alleviate the hardness of the thermally conductive gel to a certain extent, making it softer and easier to deform. When silicone is mixed with other materials, the softness of silicone can fill the tiny gaps between the materials, improve the overall adaptability and fit, and thus improve the overall performance of the composite thermally conductive gel. The elasticity of silicone can also help reduce the impact of external pressure on the thermally conductive gel and maintain the stability and durability of the material. The first adhesive layer 4 and the second adhesive layer 5 are special adhesives for firmly bonding the thermally conductive materials together. These adhesives usually have good thermal conductivity and adhesion properties to ensure that heat can be effectively conducted and maintain a stable connection.

[0022] Furthermore, the infiltration protrusions 21 are used to infiltrate the mesh structure in the thermally conductive gel central body 1 after the thermally conductive gel is installed, and then the first silicone elastic layer 2 and the second silicone elastic layer 3 as well as the thermally conductive gel central body 1 are closely fitted.

[0023] Furthermore, the length and width of the thermally conductive gel central body 1 are respectively consistent with the length and width of the upper and lower first silicone elastic layer 2 and the second silicone elastic layer 3 , and the thickness of the first silicone elastic layer 2 and the second silicone elastic layer 3 are consistent.

[0024] In this embodiment, Figure 1As shown, firstly, the second silicone elastic layer 3 is bonded to the surface of the heat dissipation component that can generate heat, and then the first silicone elastic layer 2 is bonded to the surface of another group of heat dissipation components or the surface of the shell. At this time, the infiltration protrusions 21 on the first silicone elastic layer 2 and the second silicone elastic layer 3 will penetrate into the mesh structure 11 in the thermal conductive gel core 1, thereby increasing the contact area between the first silicone elastic layer 2 and the second silicone elastic layer 3 and the heat dissipation component, improving the adhesion, and thus achieving a tighter fit. Finally, the first silicone elastic layer 2 and the second silicone elastic layer 3 are completely bonded to the surface of the heat dissipation component that generates heat, which not only increases the heat conduction area, but also ensures good heat dissipation capacity, thereby increasing the service life of the heat dissipation component.
