Thermal silicone sheet: The "invisible guardian" for effective heat dissipation of switching power supply

In the heart of electronic devices, the switching power supply quietly supports the stable conversion of energy. However, as power density increases and the size becomes increasingly compact, the problem of heat dissipation has become the core challenge restricting the performance and lifespan of the power supply. In this silent battle of heat dissipation, the thermal conductive silicone sheet acts as a "invisible guardian", building a solid barrier for the effective operation of the switching power supply.

Inside the switching power supply, components such as MOSFETs, transformers, and inductors continuously generate heat during the high-frequency switching process. Traditional cooling methods are often limited in efficiency due to uneven surfaces and gaps, for example:
1. High thermal resistance: The tiny air gap between the component and the heat sink has a high thermal resistance, hindering heat conduction.
2. Local hotspots: Uneven heat distribution leads to excessively high temperatures in certain components, accelerating aging and failure.
3. Vibration damage: Mechanical stress and vibration may damage the components, shortening the lifespan of the power supply.

Ziitek Thermal Conductive Silicone Sheet can meet the heat dissipation requirements of power switch modules. The thermal conductive silicone sheet is a particularly soft and highly compressible interface gap filler pad, featuring good flexibility, high temperature resistance, long-term stability, high dielectric strength, and excellent tear resistance. It has passed UL and ROHS certifications. This thermal conductive silicone sheet can closely adhere to the interface between the surface of the switching power chip and the heat dissipation substrate, reducing contact thermal resistance to improve heat dissipation efficiency. Its material properties determine its excellent filling effect, especially when a certain degree of compression is adopted, it can result in smaller thermal resistance and better heat dissipation performance. Moreover, the use of the thermal conductive silicone sheet is very convenient, does not easily wear out, and is convenient for the installation of the heat dissipation module. Therefore, due to its unique material properties, the thermal conductive silicone sheet becomes the "invisible guardian" that solves the heat dissipation problem.
