Publish Time: 2025-01-08
When using thermally conductive silicone sheet, leakage problem is a safety issue that needs to be seriously considered and prevented. Although thermally conductive silicone sheet has good thermal conductivity, its insulation performance cannot be ignored.1. Choose the right thermally conductive silicone sheetHigh insulation performance: Choose a thermally conductive silicone sheet with high insulation performance. Check the product specifications to ensure that its insulation resistance meets the standards.Surface treatment: Some thermally conductive silicone sheets have been specially treated on the surface to enhance their insulation performance, so you can choose such products.2. Correct installation and useClean surface: Before installing the thermally conductive silicone sheet, make sure that the contact surface of the radiator and the electronic components is clean and free of oil and dirt to avoid impurities affecting thermal conductivity and insulation performance.Flat fit: Make sure that the thermally conductive silicone sheet fits flatly and tightly between the radiator and the electronic components to avoid air gaps and bubbles, which can reduce thermal resistance and improve insulation performance.Avoid overpressure: Avoid applying excessive pressure to the thermally conductive silicone sheet during installation. Overpressure may cause the silicone sheet to crack or deform, affecting the insulation performance.3. Avoid moisture and environmental pollutionMoisture-proof treatment: When using thermally conductive silicone sheet in a humid environment, moisture-proof measures should be taken, such as using sealed packaging or applying moisture-proof agent to prevent moisture intrusion.Regular inspection: Regularly check the use of thermally conductive silicone sheet, especially for long-term use equipment, and replace aging or damaged silicone sheets in time.4. Use insulating gasketsInsulating gaskets: Add insulating gaskets between thermally conductive silicone sheet and electronic components or between radiator and thermally conductive silicone sheet to increase the insulation layer and further improve the insulation performance.Multi-layer insulation: In high-demand applications, multi-layer insulation structures can be used to ensure full isolation.5. Design and layout optimizationReasonable layout: When designing the heat dissipation system, reasonably arrange the positions of the radiator and electronic components to avoid direct contact between the high-voltage part and the radiator.Isolation design: For high voltage parts, consider using insulating materials for isolation to ensure a safe distance.6. Monitoring and maintenanceMonitoring system: Install leakage monitoring equipment to monitor the leakage of equipment in real time, and promptly detect and deal with problems.Maintenance plan: Develop a regular maintenance plan, check the use of thermally conductive silicone sheet, clean the contact surface, and ensure good thermal conductivity and insulation performance.Through the above measures, the leakage problem that may occur during the use of thermally conductive silicone sheet can be effectively avoided, ensuring the safe and stable operation of the equipment.
