Phase change materials (PCM) are innovative substances. Such PCMs are capable of storing and releasing thermal energy during phase changes such as melting and solidification. This property makes them very effective in thermal energy storage. This is because they can maintain a stable temperature by absorbing excess heat and releasing it when needed.PCMs play a pivotal role in thermal management. These roles are primarily in applications such as electric vehicles and energy storage systems. Because temperature regulation in these industries is critical to performance and safety.

How Phase Change Materials Store and Release Energy?
Phase change material (PCM) is a material that stores and releases large amounts of heat during a phase change. Common phase change processes are melting and solidification. This process is similar to an ice cube melting by absorbing a large amount of heat from its surroundings while the temperature remains constant.PCBs utilize this principle to maintain a stable temperature environment. Therefore, it is well suited for construction as well as electronics and other fields.
In building materials, PCM can be integrated into walls and roofs. The material can store heat during the day and release it at night, thus reducing the need for artificial heating or cooling. This not only optimizes energy consumption, but also improves thermal comfort for residents. For electronic devices, especially those prone to overheating, PCMs act as thermal buffers. They absorb excess heat generated during operation and release it when the equipment cools down. This effectively prevents damage and extends the life of the equipment.
PCMs (phase change materials) effectively manage heat over time. They can delay the release of stored energy, which is useful when stable temperatures need to be maintained for long periods of time. This property is invaluable, for example, in solar thermal storage systems and temperature-controlled shipping containers.
Types of Phase Change Materials: Organic, Inorganic and Eutectic Phase Change Materials
Phase change materials (PCMs) can be categorized into organic, inorganic and eutectic types. Each of these PCMs has different characteristics. Let’s take a look at the differences below:
Organic PCMs such as paraffins and fatty acids are popular because of their chemical stability and wide range of melting points. They are non-toxic, non-corrosive and have a high latent heat of fusion. These characteristics make them suitable for applications such as increased building energy efficiency and improved thermal comfort. However, they have low thermal conductivity. This can be addressed by adding conductive fillers or encapsulating them with materials with better thermal properties.
Inorganic PCMs (such as salt hydrates and metal alloys) have high thermal conductivity and can store large amounts of heat. They work well in high-temperature applications because they are non-flammable and have excellent heat transfer properties. This allows for rapid storage and release of energy. However, they can face challenges such as phase separation and overcooling. The addition of nucleating and thickening agents helps to address these issues.
Eutectic PCMs are mixtures of different materials with melting points that can be adjusted for specific applications. They combine the properties of individual components to achieve a balance between high energy storage and stable phase transition. For example, fatty acid eutectics typically perform better than each component alone. However, they can be more costly and may have a lower total latent heat capacity.
At Trumonytechs, we utilize the advantages of each PCM in our materials development process. Our goal is to create innovative solutions that maximize their benefits and minimize their limitations. Our expertise focuses on enhancing thermal management systems for electric vehicles, energy storage and heat transfer applications. This ensures efficient temperature control and extends the life of advanced equipment.
Enhancing PCM Efficiency with Thermal Interface Materials (TIMs)
Thermal Interface Materials (TIM) are critical to improving the thermal performance of Phase Change Materials (PCM). Thermal Interface Materials (TIMs) are specially designed materials that fill the small gaps between the heating element and the cooling system. This improves the efficiency of heat transfer. TIMs are especially important when PCMs are used for thermal energy storage and temperature control.
At Trumonytechs, we develop advanced TIMs that significantly enhance the performance of PCMs.. Our TIMs have high thermal conductivity and are flexible enough to adapt to different surface shapes. This flexibility ensures optimal contact between the heat source and the PCM, which is essential for efficient heat transfer. The PCM then stores this energy as latent heat during the phase change process.
One of our key innovations is the manufacture of TIM, which not only improves heat transfer but also extends the life of the PCM. By reducing thermal stresses, our TIMs help prevent leakage and maintain the integrity of the PCM through multiple phase changes. This is critical in applications such as construction materials and electronics, where the PCM needs to maintain a stable temperature.
We also use proprietary encapsulation technology to prevent PCM leakage. This leakage is typically caused by volume expansion during phase change. Our encapsulation technology protects the PCM from environmental factors that can cause degradation, thereby increasing its long-term durability. In addition, our TIM optimizes the thermal contact between the PCM and the heat sink. This reduces thermal resistance and maximizes heat transfer efficiency.
Trumonytech’s TIM is critical to improving the efficiency and durability of PCMs in a variety of applications. By filling the gap between the PCM and the heat sink, our TIMs ensure that the PCM efficiently stores and releases heat. This provides a reliable temperature control and thermal management solution.
