With the passage of time, social economy and technology have gradually developed. Devices that used to only exist for certain specific groups of people have now become widely popular. The high-tech that used to be imaginative in movies, TV shows, and novels has now become a necessity in people's daily lives. It can be said that the progress of the times has driven people's material and spiritual prosperity.
The development of high-tech cannot be separated from people's exploration and practice of ignorant fields. With the development of technology in recent years, the field of thermal management has emerged and its weight has been increasing year by year. Thermal conductive silicone film, as a common thermal interface material in the market, is widely recognized and respected in the field of thermal management. What is the charm of thermal conductive silicone film that makes people so addicted?
Thermal conductive silicone pad is a gap filling thermal pad made of silicone resin as the substrate and added with temperature resistant and thermal conductive materials. It has high thermal conductivity, low interface thermal resistance, insulation, compressibility and other characteristics. Due to its soft hardness, it can realize small thermal resistance under low pressure, while eliminating air between contact surfaces and fully filling the rough surfaces between contact surfaces, improving the thermal conductivity of contact surfaces. Due to the excellent filling effect of the thermal conductive silicone sheet, it can effectively transfer the heat from the heat source to the shell, and the thermal conductive silicone sheet has good compressibility and elasticity, which can serve as a good shock absorber pad.
When purchasing thermal conductive silicone sheets, people often pay attention to several essential parameters such as thermal conductivity, thermal resistance, compression ratio, size and thickness, but often overlook the toughness parameter. So, how much position does toughness occupy in the parameters of thermal conductive silicone sheets?
Firstly, we need to clarify what resilience is? Resilience, a physical concept, refers to the ability of materials to absorb energy during plastic deformation and fracture processes. Simply put, the better the toughness, the lower the possibility of brittle fracture, and toughness is also closely related to the elasticity of thermal conductive silicone film.
As is well known, thermal conductive silicone sheet is a soft thermal pad that has elasticity. In people's use, the elasticity is fully placed in the operating environment of products, such as engine radiators, new energy vehicle battery packs, large CNC machine tools, etc. These devices will experience high vibration frequencies during operation. The use of thermal conductive silicone sheet can serve as a shock absorber pad and also play a role in heat dissipation and conduction. At the same time, it can fully fill the interface and make full contact between the two in tolerance situations, reducing the interface thermal resistance.
The working life of thermal conductive silicone film is relatively long, and it is inevitable to experience vibration and wear during use. Therefore, a resilient thermal conductive silicone film can reduce the deformation of the thermal conductive silicone film caused by external forces during use, and prevent it from performing its thermal conductivity function. Therefore, customers need to understand the operation of the equipment when purchasing thermal conductive silicone film, and choose a suitable resilient thermal conductive silicone film to ensure long-term and reliable operation of the equipment.
