Description

Technical Field

[0001] The utility model relates to the technical field of thermally conductive silicone sheets, in particular to a thermally conductive silicone sheet with high thermal conductivity and insulation silicone cloth. Background Art

[0002] With the miniaturization and high integration of integrated circuits, the assembly density of electronic components continues to increase. While providing powerful functionalities, it also leads to a sharp increase in their working power consumption and heat generation. If electronic products run for too long, they will cause the products to become hot and generate heat. In severe cases, they may even jam or explode, thus affecting the user experience.

[0003] At present, the commonly used heat dissipation materials are mainly thermal conductive silicone sheets, which are organic silicone materials with low thermal conductivity. They can only meet the use requirements of ordinary integrated circuits, but are not enough to solve the cooling needs of high-power electronic equipment, and the use effect is not good. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high thermal conductivity insulating silicone cloth thermal conductive silicone sheet to solve the technical problems raised by the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a high thermal conductivity insulating silicone cloth thermal conductive silicone sheet, comprising a silicone layer for forming a core layer of the thermal conductive silicone sheet, a support layer for providing mechanical strength is arranged on one side of the silicone layer, an insulating layer for providing electrical insulation performance is arranged on the support layer, an adhesive layer fixed on the target material is arranged on the other side of the silicone layer, a release layer for preventing the adhesive performance of the adhesive layer from being affected is arranged on the outer end surface of the adhesive layer, an outer protective frame is arranged on the outer frame of the silicone layer, and a plurality of first air holes are equidistantly arranged on the end surface of the silicone layer, and an air flow channel that is interconnected and distributed in the transverse and longitudinal directions is arranged at the center of each of the first air holes and on the surface of the silicone layer.

[0006] Preferably, a plurality of second pores are provided on the end surface of the adhesive layer, and each of the second pores corresponds one-to-one to a first pore provided on the silicone layer.

[0007] Preferably, a core block is arranged at the center of the end surface of the insulating layer.

[0008] Preferably, one side of the airflow channel is open and extends to the end of the outer protective frame to which the outer frame on the silicone layer is fixed.

[0009] Preferably, the outer protective frame and the core block are both made of elastic rubber.

[0010] Preferably, the support layer is made of copper foil.

[0011] Preferably, the insulating layer is made of a polyimide film, and the insulating layer is coated on the outer surface of the supporting layer.

[0012] By means of the above technical solution, the utility model provides a high thermal conductivity insulating silicone cloth thermal conductive silicone sheet, which has at least the following beneficial effects:

[0013] 1. The utility model provides the first pores on the silicone layer, the airflow channels and the second pores on the adhesive layer. The plurality of second pores formed on the adhesive layer and the plurality of first pores formed on the silicone layer are used in combination to avoid heat accumulation on the surface of the target material, and is used for heat extraction. The extracted heat is transported to the outside through the airflow channels that are longitudinally and transversely connected and distributed on the first pores, and a high thermal conductivity effect is further achieved through the change of the physical structure on the basis of the existing thermal conductivity.

[0014] 2. Due to the arrangement of the outer protective frame and the core block, the utility model not only increases the insulation performance while ensuring the supporting strength, but also the outer protective frame and the core block made of elastic rubber increase the shock-absorbing and buffering performance of the utility structure, provide a certain degree of buffering protection for the target material, and have a good use effect.
