With the growing global demand for renewable energy, energy storage technology has become a crucial part of energy management. In energy storage systems, inverters serve as key equipment to convert DC power to AC power, or vice versa. However, the high power density design and high-frequency operation of inverters generate significant heat, and excessive temperature can damage internal components, reducing the lifespan and efficiency of the device. Therefore, heat dissipation management is a core issue in ensuring the stable operation of inverters. Thermal grease, as an efficient thermal conductive material, plays an irreplaceable role in addressing the heat dissipation challenges of energy storage inverters.
Basic Properties of Thermal Grease
Thermal grease is a thermal interface material made by mixing silicone oil with thermal conductive fillers. It has the following key characteristics:
1. Excellent thermal conductivity: Thermal grease contains high thermal conductivity fillers such as aluminum oxide, boron nitride, carbon nanotubes, etc., which can quickly transfer heat and reduce the thermal resistance between electronic components and heat sinks.
2. Low volatility and high stability: Due to its silicone-based properties, thermal grease exhibits extremely low volatility in high-temperature environments and remains chemically stable over long-term use, making it suitable for long-term operation under high temperatures.
3. Good electrical insulation: While providing efficient thermal conductivity, thermal grease maintains electrical insulation, preventing short circuits and other problems.
4. Softness and low adhesion: It can effectively fill micro gaps, ensuring efficient heat transfer between components and heat sinks, while also being easy to apply and maintain.
