Description

Technical Field

[0001] This utility model relates to the field of thermally conductive silicone pad technology, and in particular to a thermally conductive silicone pad with good heat dissipation effect. Background Technology

[0002] "Thermal conductive silicone pads" are thermally conductive media materials synthesized through a special process using silicone as the base material and adding various auxiliary materials such as metal oxides. In the industry, they are also known as thermal conductive silicone pads, thermal conductive silicone sheets, soft thermal conductive pads, thermal conductive silicone gaskets, etc. They are specially designed and manufactured for heat transfer through gaps. They can fill gaps, open up thermal channels between heat-generating and heat-dissipating parts, effectively improve heat transfer efficiency, and also play a role in insulation, shock absorption, and sealing. They can meet the design requirements of miniaturization and ultra-thinness of equipment. They are highly processable and practical, and have a wide range of applicable thicknesses, making them an excellent thermally conductive filling material.

[0003] Currently, conventional thermal conductive silicone pads are generally made of silicone, and their heat dissipation effect may be relatively average. If used for too long, the silicone pad may overheat, resulting in a decrease in thermal conductivity. At the same time, the heat sink may be damaged due to the squeezing between the component and the heat sink.

[0004] Therefore, those skilled in the art have provided a thermally conductive silicone pad with good heat dissipation to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a thermally conductive silicone sheet with good heat dissipation. Through the design of the heat dissipation mechanism, the thermal conductivity of the silicone sheet can be effectively improved, thereby increasing its service life. Furthermore, through the design of the reinforcing mechanism, the strength of the thermally conductive sheet can be improved, thereby preventing the thermally conductive sheet from being damaged by compression.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A thermally conductive silicone pad with good heat dissipation performance includes a thermally conductive pad body and an easy-tear protective film. A heat dissipation mechanism is provided at the lower end of the easy-tear protective film, and a reinforcing mechanism is provided inside the thermally conductive pad body.

[0008] The heat dissipation mechanism includes a heat-conducting sheet body, an adhesive layer at the upper end of the heat-conducting sheet body, a first heat-absorbing layer at the lower end of the adhesive layer, an insulating heat-conducting layer at the lower end of the first heat-absorbing layer, a heat-conducting silicone sheet at the lower end of the insulating heat-conducting layer, a second heat-absorbing layer at the lower end of the heat-conducting silicone sheet, and a heat dissipation layer at the lower end of the second heat-absorbing layer.

[0009] The above technical solution, through the heat dissipation mechanism, can effectively improve the thermal conductivity of the thermal silicone pad, thereby increasing its service life.

[0010] Furthermore, the reinforcing mechanism includes a reinforcing block, the upper end of which is provided with a copper mesh, the lower end of which is provided with hexagonal boron nitride, and the lower end of which is provided with an aluminum sheet;

[0011] The above technical solution, through the reinforcement mechanism, can improve the strength of the heat-conducting sheet, thereby preventing it from being damaged by compression.

[0012] Furthermore, the adhesive layer is composed of silicone thermally conductive adhesive;

[0013] Through the above technical solution, the silicone thermally conductive adhesive has good adhesion and also good thermal conductivity.

[0014] Furthermore, the first heat-absorbing layer and the second heat-absorbing layer are composed of ceramic powder and carbon fiber composite material and graphite material, respectively;

[0015] Through the above technical solutions, ceramic powder-carbon fiber composite materials and graphite materials have excellent thermal conductivity as well as excellent flexibility.

[0016] Furthermore, the insulating and thermally conductive layer is composed of a fluoroplastic film material;

[0017] Through the above technical solutions, fluoroplastic film materials have excellent insulation and thermal conductivity.

[0018] Furthermore, the heat dissipation layer is composed of graphene.

[0019] Through the above technical solutions, graphene materials have excellent heat absorption and dissipation capabilities.

[0020] Furthermore, the reinforcing blocks are arranged in an "I" shape and are evenly distributed inside the heat-conducting sheet body;

[0021] By using the above technical solution and setting it in an "I" shape, the strength of the heat-conducting plate can be greatly improved.

[0022] Furthermore, adhesive layers are provided at both the upper and lower ends of the heat-conducting sheet body, and an easy-tear protective film is provided on the outer wall of the adhesive layer;

[0023] Through the above technical solution, the easy-tear protective film can protect the adhesive layer and can also be quickly peeled off, making it easy to stick to the surface of the component.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a thermally conductive silicone pad with good heat dissipation effect. After peeling off the easy-tear protective film, the adhesive layer is attached to the surface of the component. When the component generates heat, the first heat-absorbing layer absorbs the heat, and then the heat is conducted out through the insulating thermally conductive layer, which also has insulation capabilities to prevent damage caused by leakage. The heat enters the second heat-absorbing layer through the thermally conductive silicone pad, and finally the heat is discharged from the body of the thermally conductive pad through the heat dissipation layer. Through the heat dissipation mechanism, the thermal conductivity of the silicone pad can be effectively improved, thereby increasing the service life.

[0026] 2. The thermally conductive silicone sheet proposed in this utility model has good heat dissipation effect. The heat can also be absorbed by the copper mesh. Since hexagonal boron nitride has a good thermal conductivity, it can conduct the heat to the aluminum sheet, which is then absorbed by the second heat absorption layer and dissipated through the heat dissipation layer. At the same time, the copper mesh, hexagonal boron nitride and aluminum sheet are shaped into an "I" shape, which can effectively improve the overall strength of the thermally conductive sheet and prevent the thermally conductive sheet from being crushed and damaged.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A first heat-absorbing layer 103 is disposed at the lower end of the adhesive layer 102. An insulating heat-conducting layer 104 is disposed at the lower end of the first heat-absorbing layer 103. A thermally conductive silicone sheet 105 is disposed at the lower end of the insulating heat-conducting layer 104. A second heat-absorbing layer 106 is disposed at the lower end of the thermally conductive silicone sheet 105. A heat dissipation layer 107 is disposed at the lower end of the second heat-absorbing layer 106. The adhesive layer 102 is composed of silicone thermally conductive adhesive, which has excellent thermal conductivity. The first heat-absorbing layer 103 and the second heat-absorbing layer 106 are composed of ceramic powder and carbon fiber composite material and graphite material, respectively. The ceramic powder and carbon fiber composite material and graphite material have good thermal conductivity and good flexibility. The insulating and thermally conductive layer 104 is composed of fluoroplastic film material, which has good insulation and thermal conductivity.

[0037] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The reinforcing mechanism 2 includes a reinforcing block 201. The upper end of the reinforcing block 201 is provided with a copper mesh 202, the lower end of the copper mesh 202 is provided with a hexagonal boron nitride 203, and the lower end of the hexagonal boron nitride 203 is provided with an aluminum sheet 204. The reinforcing mechanism 2 can improve the strength of the heat-conducting plate and prevent it from being crushed. The reinforcing block 201 is shaped like an "I" and is evenly distributed inside the heat-conducting plate body 101. The "I" shape can effectively improve the strength of the heat-conducting plate. The upper and lower ends of the heat-conducting plate body 101 are provided with an adhesive layer 102. The outer wall of the adhesive layer 102 is provided with an easy-tear protective film 3. The easy-tear protective film 3 can protect the adhesive layer 102 and can also be quickly peeled off, making it easy to stick to the surface of the component.

[0038] Working principle: After peeling off the easy-tear protective film 3, the adhesive layer 102 is attached to the surface of the component. When the component generates heat, the first heat-absorbing layer 103 absorbs the heat, and then the heat is conducted out through the insulating heat-conducting layer 104.

The heat can also be absorbed by the copper mesh 202. Since the hexagonal boron nitride 203 has excellent thermal conductivity, it can conduct the heat to the aluminum sheet 204, and then be absorbed by the second heat-absorbing layer 106. The heat is then dissipated through the heat dissipation layer 107. At the same time, the copper mesh 202, hexagonal boron nitride 203 and aluminum sheet 204 are shaped like an "I", which can effectively improve the overall strength of the heat-conducting sheet.
