Ultra-thin and customizable: The key to breaking the deadlock of heat dissipation in narrow spaces with thermal silicone sheets

Thermal conductive silicone sheets are made with silicone gel as the base material and high thermal conductivity metal oxide powders such as aluminum oxide and boron nitride added, and are formed through a special process. They possess excellent thermal conductivity and flexibility. Compared with the rigidity of traditional metal heat sinks and the easy loss of thermal paste, they can be embedded in tiny gaps like a "film" and can be customized to fit various scenarios, well meeting the strict requirements for heat dissipation materials in small spaces.

The ultra-thin feature is the core competitiveness that breaks through the spatial limitations. In the heat dissipation design of a certain ultra-thin tablet computer, a 0.2mm thick thermal conductive silicone sheet successfully conducted the CPU heat to the outer casing of the device, reducing the operating temperature by 12℃ and solving the "overheating" problem of thin and light models.

The customization capability enables thermal conductive silicone sheets to adapt to diverse and complex scenarios. In terms of size customization, they can be processed into circular, irregular or even perforated shapes according to the internal structure of the equipment. For instance, the long-strip thermal conductive silicone sheets customized for the battery packs of new energy vehicles can precisely fit the narrow channels between battery cells, achieving uniform heat dissipation. In terms of performance customization, by adjusting the proportion of thermal conductive powder, the thermal conductivity can be controlled within the range of 1.2-25W/m・K. Meanwhile, insulation, aging resistance or flame retardancy can be enhanced as required. A certain communication equipment manufacturer customized thermal conductive silicone sheets for the RRU module of 5G base stations. These sheets not only have a thickness of only 0.3mm but also possess the characteristics of withstanding high and low temperatures, ensuring stable heat dissipation of the base station under abnormal conditions and reducing the equipment failure rate by 30%.

From the perspective of application fields, ultra-thin and customizable thermal conductive silicone sheets have become a "heat dissipation necessity" in multiple industries. In the consumer electronics sector, they support the thin and light design of foldable screen phones and ultra-thin laptops; in the new energy sector, they provide safe heat dissipation guarantees for battery packs and charging piles; in the industrial sector, they enable industrial cameras and sensors to work stably for long periods in confined spaces; in the medical equipment sector, their insulating and non-volatile properties meet the strict requirements of medical instruments. As electronic devices continue to develop towards miniaturization and high power density, the demand for heat dissipation in small spaces will continue to increase.
