Description

Technical Field

[0001] The utility model relates to the technical field of silica gel pads, in particular to a heat-conducting silica gel pad. Background Art

[0002] Silica gel pads are a type of product with a large market demand in silica gel products. They have various excellent properties and a wide range of application fields. According to the application fields and properties, they can be divided into various types, such as heat-conducting silica gel pads, silica gel heat-insulating pads, silica gel gaskets, etc.

[0003] In electronic devices, in order to effectively reduce the temperature of electronic components, silica gel pads are mostly used for heat dissipation. However, the existing heat-conducting silica gel pads generally have a general heat-conducting effect and cannot quickly reduce the temperature of electronic components to ensure the stable operation of the device. Moreover, the flammability of the silica gel pads is relatively high and they are easily ignited, thus causing a fire or accelerating the spread of the fire. Content of the Utility Model

[0004] The utility model mainly provides a heat-conducting silica gel pad with good heat-conducting effect and flame retardancy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a heat-conducting silica gel pad, including a release film. The bottom of the release film is adhered with a first heat-conducting layer. The bottom of the first heat-conducting layer is provided with a second heat-conducting layer. The bottom of the second heat-conducting layer is provided with a reinforcement layer. The bottom of the reinforcement layer is provided with a flame-retardant layer. The bottom of the flame-retardant layer is provided with an electromagnetic shielding layer. The bottom of the electromagnetic shielding layer is provided with a wear-resistant layer. When using this heat-conducting silica gel pad, people can tear the release film from the silica gel pad, so that the first heat-conducting layer is attached to the component to be cooled, and the heat-conducting silica gel pad is fixed by means of the viscosity of the first heat-conducting layer, and then the wear-resistant layer is attached to the heat-dissipating component.

[0006] Preferably, the release film adopts a polyester film layer, and the thickness of the release film is 25 - 50μm. The release film adhered to the surface of the heat-conducting silica gel pad can not only prevent the heat-conducting silica gel pad from being damaged due to friction and scratching, but also prevent impurities such as dust and oil stains from adhering to the surface of the heat-conducting silica gel pad, resulting in the loss of viscosity of the heat-conducting silica gel pad, and can maintain the stability of viscosity.

[0007] Preferably, the first heat-conducting layer adopts a silica gel layer, and the thickness of the first heat-conducting layer is 0.5 - 10mm. The first heat-conducting layer made of silica gel is the main part of the silica gel heat-conducting layer and has excellent heat-conducting performance. It can effectively conduct heat from the heat source to the heat-dissipating system, thereby reducing the accumulation of heat inside the device and ensuring the normal operation and stability of the device.

[0008] Preferably, the second heat-conducting layer is made of a polyimide layer, and the thickness of the second heat-conducting layer is 0.15 - 0.7 mm. The polyimide layer is tightly combined with the silica gel layer, enabling heat to be quickly transferred through the polyimide layer to the silica gel, thereby assisting the silica gel layer to achieve rapid heat dissipation. Moreover, the polyimide material has excellent high-temperature resistance, ensuring that the heat-conducting silica gel pad can still operate normally at high temperatures.

[0009] Preferably, the reinforcing layer is made of a fiberglass cloth layer, and the thickness of the reinforcing layer is 30 - 180 μm. The fiberglass cloth has a very high tensile strength, which can significantly enhance the structural stability of the heat-conducting silica gel pad and extend its service life.

[0010] Preferably, the flame-retardant layer is made of an alumina layer, and the thickness of the flame-retardant layer is 5 - 25 mm. Alumina has good high-temperature stability, which can significantly improve the flame-retardant effect of the heat-conducting silica gel pad. When the heat-conducting silica gel pad catches fire, it can also slow down the spread speed of the flame, thus protecting the safety of equipment and personnel.

[0011] Preferably, the electromagnetic shielding layer is made of a copper-aluminum alloy layer, and the thickness of the electromagnetic shielding layer is 0.1 - 20 mm. The wear-resistant layer is made of a wear-resistant resin layer, and the thickness of the wear-resistant layer is 5 - 80 mm. The electromagnetic shielding layer can block or reflect electromagnetic waves, preventing electromagnetic radiation from affecting the normal operation of the equipment, effectively improving the stability and reliability of the equipment. The wear-resistant layer can reduce surface wear during long-term contact with the heat-dissipating element and maintain its good heat-conducting performance.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, the release film can prevent the heat-conducting silica gel pad from being damaged by external forces, ensuring the heat dissipation effect and adhesiveness of the heat-conducting silica gel pad. The heat-conducting silica gel pad can quickly conduct heat from the heat source to the heat dissipation system, ensuring the stable operation of the equipment, avoiding equipment damage caused by high temperature. The reinforcing layer significantly improves the structural strength of the heat-conducting silica gel pad, extends the service life of the heat-conducting silica gel pad, and reduces the time and cost of replacement. The reinforcing layer and the flame-retardant layer enable the silica gel pad to not only operate normally in a high-temperature environment but also have excellent flame-retardant performance, slowing down the spread speed of the flame in case of a fire and protecting the safety of equipment and personnel.

[0014] 2. In the present utility model, the electromagnetic shielding layer can prevent electromagnetic radiation from interfering with the normal operation of the equipment by blocking or reflecting electromagnetic waves, thereby improving the overall performance of the equipment. The wear-resistant layer reduces the wear caused by the contact process between the heat-conducting silica gel pad and the heat-dissipating element, enabling it to maintain good heat-conducting performance.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a heat-conducting silica gel pad, including a release film 1, the bottom of the release film 1 is adhered with a first heat-conducting layer 2, the bottom of the first heat-conducting layer 2 is provided with a second heat-conducting layer 3, the bottom of the second heat-conducting layer 3 is provided with a reinforcement layer 4, the bottom of the reinforcement layer 4 is provided with a flame-retardant layer 5, the bottom of the flame-retardant layer 5 is provided with an electromagnetic shielding layer 6, and the bottom of the electromagnetic shielding layer 6 is provided with a wear-resistant layer 7. When the heat-conducting silica gel pad needs to be used, people can tear off the release film 1 from the silica gel pad, so that the first heat-conducting layer 2 is attached to the component that needs to dissipate heat, and the heat-conducting silica gel pad is fixed by means of the viscosity of the first heat-conducting layer 2, and then the wear-resistant layer 7 is attached to the heat-dissipating component.

[0024] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the release film 1 uses a polyester film layer, and the thickness of the release film 1 is 25 - 50 μm. The release film 1 is adhered to the surface of the heat-conducting silicone pad, which can not only prevent the heat-conducting silicone pad from being damaged due to friction and scratching, but also prevent impurities such as dust and oil stains from adhering to the surface of the heat-conducting silicone pad, resulting in the loss of stickiness of the heat-conducting silicone pad, and can maintain the stability of the stickiness.

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first heat-conducting layer 2 uses a silicone layer, and the thickness of the first heat-conducting layer 2 is 0.5 - 10 mm. The first heat-conducting layer 2 is made of silicone and is the main part of the silicone heat-conducting layer, with excellent heat-conducting performance. It can effectively conduct heat from the heat source to the heat dissipation system, thereby reducing the accumulation of heat inside the device and ensuring the normal operation and stability of the device.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the second heat-conducting layer 3 uses a polyimide layer, and the thickness of the second heat-conducting layer 3 is 0.15 - 0.7 mm. The polyimide layer is closely combined with the silicone layer, enabling heat to quickly transfer through the polyimide layer to the silicone, thereby assisting the silicone layer to achieve rapid heat dissipation. Moreover, the polyimide material has excellent high-temperature resistance, ensuring that the heat-conducting silicone pad can still work normally at high temperatures.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reinforcement layer 4 uses a fiberglass cloth layer, and the thickness of the reinforcement layer 4 is 30 - 180 μm. The fiberglass cloth has a very high tensile strength, which can significantly improve the structural stability of the heat-conducting silicone pad and extend its service life.

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flame-retardant layer 5 uses an alumina layer, and the thickness of the flame-retardant layer 5 is 5 - 25 mm. Alumina has good high-temperature stability, which can significantly improve the flame-retardant effect of the heat-conducting silicone pad. When the heat-conducting silicone pad catches fire, it can also slow down the spread speed of the flame, thereby protecting the safety of the device and personnel.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the electromagnetic shielding layer 6 is made of a copper-aluminum alloy layer, and the thickness of the electromagnetic shielding layer 6 is 0.1 - 20 mm. The wear-resistant layer 7 is made of a wear-resistant resin layer, and the thickness of the wear-resistant layer 7 is 5 - 80 mm. The electromagnetic shielding layer 6 can block or reflect electromagnetic waves, preventing electromagnetic radiation from affecting the normal operation of the device, effectively improving the stability and reliability of the device. The wear-resistant layer 7 can reduce surface wear during long-term contact with the heat dissipation element and maintain its good heat conduction performance.

[0030] Usage method and working principle of this device: When using this thermal conductive silicone pad, the user will first gently tear off the release film 1 on the surface, exposing the highly viscous thermal conductive layer 1-2. Subsequently, the thermal conductive layer 1-2 is closely attached to the element that needs to dissipate heat, and the silicone pad is automatically fixed by its excellent viscosity to ensure a stable connection. Immediately afterwards, the heat dissipation element is brought into contact with the wear-resistant layer 7. The release film 1 not only effectively prevents the thermal conductive silicone pad from being damaged during storage or transportation, but also avoids the attachment of pollutants such as dust and oil stains, thereby maintaining the stable viscosity of the thermal conductive silicone pad and ensuring that it can quickly and firmly adhere to the heat dissipation surface during application. The material of the thermal conductive layer 1-2 is silicone, which, as the main body of the thermal conductive silicone pad, can efficiently transfer heat from the heat source to the heat dissipation system, greatly reducing the accumulation of heat inside the device. The built-in thermal conductive layer 2-3 closely cooperates with the thermal conductive layer 1-2 to form an efficient heat conduction channel. Polyimide, with its excellent high-temperature resistance and thermal conduction ability, helps the silicone dissipate heat more quickly, ensuring that the thermal conductive silicone pad can still operate stably in a high-temperature environment. The reinforcing layer 4 of fiberglass cloth significantly improves the structural strength of the thermal conductive silicone pad, effectively extending the service life of the gasket and maintaining the structural integrity even under harsh working conditions. The alumina flame-retardant layer 5 endows the thermal conductive silicone pad with excellent flame-retardant performance. With its good high-temperature stability, it can slow down the spread of flames in the event of a sudden fire, providing a solid line of defense for the safety of the device and personnel. The electromagnetic shielding layer 6 effectively blocks or reflects electromagnetic waves, preventing electromagnetic radiation from interfering with the normal operation of the device and further enhancing the stability and reliability of the device. The wear-resistant layer 7, as the direct contact layer between the thermal conductive silicone pad and the heat dissipation element, can reduce surface wear during long-term contact, providing strong support for the long-term stable operation of the device.
