Properties, principles and applications of thermal conductive phase change materials

Thermal conductive phase change materials are special thermal management materials, and their characteristics, principles and applications are as follows:

Features:
1. High latent heat of phase change: thermally conductive phase change materials can absorb or release a large amount of latent heat in the process of phase change, which makes it an effective heat storage material.
2, excellent thermal conductivity: thermal phase change materials have high thermal conductivity, can quickly transfer heat to the heat storage area or release to the surrounding environment, to ensure the effective transfer of heat in the system.
3. Wide range of temperature adjustment: the phase change temperature of thermal conductive phase change material can be realized by adjusting the formula of the material, so it can adapt to a variety of temperature environments and meet different application needs.
4, energy saving and environmental protection: thermal conductivity phase change materials in building energy saving, thermal management and other fields of excellent performance, help to reduce the energy consumption of buildings, to achieve the effect of environmental protection and energy saving.

Principle:
The core principle of thermal conductive phase change materials lies in their phase transformation characteristics. When a material reaches a specific phase transition temperature, it changes from one physical state (such as solid) to another (such as liquid). This phase transition process is accompanied by the absorption or release of a large amount of latent heat. Therefore, thermal conductive phase change materials can effectively absorb or release heat when the temperature changes, and realize the regulation of temperature.

Applications: Thermal conductive phase change materials are widely used in many fields.

1. Battery thermal management: thermal conductive phase change materials can be used for battery thermal management to prevent battery thermal runaway. When the battery temperature increases, the thermal conductive phase change material absorbs heat and undergoes a phase transition, storing the heat inside the material, thereby slowing down the rate of increase in the battery temperature.

2. Heat dissipation of electronic devices: thermal conductive phase change materials can fill the small irregular gaps between electronic components and heat sinks, increase the contact area and discharge the air to achieve effective heat dissipation. It is often used for heat dissipation of high-frequency microprocessors, laptops, cache chips and other electronic devices.

3. Renewable energy: With the development and application of renewable energy, thermal conductive phase change materials have been widely used in solar energy, wind energy, geothermal energy and other fields. For example, in solar water heaters, thermal conductive phase change materials can absorb the heat radiated by the sun and store it for heating domestic water.

In a word, thermal conductive phase change materials play an important role in thermal management, energy utilization and other aspects due to their unique characteristics and wide application fields. With the continuous progress of technology and the expansion of application fields, thermal conductive phase change materials are expected to bring innovation and breakthrough to more fields in the future.
