Detailed Explanation of Thermal Conductive Silicone: Application, Performance, and Optimization Selection
1、 Introduction to Thermal Conductive SiliconeIn today’s increasingly miniaturized and integrated electronic devices, how to effectively solve the problem of internal heat accumulation in devices has become a technical challenge that urgently needs to be overcome. Thermal conductive silicone, as an efficient thermal conductive material, has emerged in this context and quickly gained widespread application. This article will comprehensively and deeply introduce thermal conductive silicone from multiple perspectives such as definition, classification, and working principle. 1.1 DefinitionThermal conductive silicone is a polymer compound with excellent thermal conductivity and good insulation properties, mainly composed of silicone oil, thermal conductive filler, and a small amount of additives. It can effectively fill the gap between the heating element and the heat sink, reduce the contact thermal resistance, and achieve fast and effective heat transfer.1.2 ClassificationAccording to their different forms, thermal conductive silicone can be divided into two categories: liquid (such as thermal paste) and solid (such as thermal pad); According to the usage scenario, it can be further divided into various types such as universal and specialized.2、 Working principle of thermal conductive siliconeThe reason why thermal conductive silicone can exert excellent heat dissipation effect lies in its unique physical and chemical properties:Low thermal resistance: By optimizing the formula design, the material itself has an extremely low thermal resistance value;Good wettability: It can adhere well to metal surfaces, forming a continuous and uniform thin film layer;Soft and malleable: even in the face of unevenness or small gaps, it can tightly adhere to ensure the best heat conduction path;Long term stability: resistant to high temperature aging, not easy to evaporate and dry, ensuring stable performance for a long time.3、 Application scenariosWith the development of technology, thermal conductive silicone has been widely used in various fields:Consumer electronics products: Used for heat dissipation of key components such…
