The 70°C PCM Demonstrates Excellent Reversibility Throughout The Phase Change Process - Not Only Enhances Its Durability But Also Maximizes Its Energy Storage And Release Capabilities

Scope of application:

• Phase change materials (PCM) show high energy storage density, which is conducive to the storage and efficient utilization of energy. For low temperature phase change materials, their applications range can be from air-conditioning and construction industrial to industrial refrigeration, transportation and storage of food and medicine.
• This paper provides a systematic introduction to phase change materials for subzero applications, and reviews recent research on phase change materials for subzero applications from the perspectives of supercooling, chronic stability and thermal conductivity.
• In view of the severe supercooling of the aqueous PCM systems and metal corrosion of salt solution, the relevant research in recent years show that these problems can be solved by using suitable nucleating agents and improving the compatibility between the PCM and the nucleating agent, avoiding nanoparticles agglomeration and encapsulating PCM with stainless steel or polymer materials.
• The problem of low thermal conductivity of non-aqueous PCM systems can be solved by introducing nanoparticles and supporting materials with high thermal conductivity or encapsulating PCM. Finally, as for the aggregation of nanoparticles and the latent heat loss caused by the introduction of support materials and microencapsulated PCM, it is worth trying to improve the compatibility of nanoparticles and support materials with PCM.

Performance Table:

1. Stable performance and form

• It is solid before and after the phase change, and there is no leakage.

2. High thermal conductivity

• It can release or accumulate cold energy in time.

3. Accurate and balanced temperature control

• The phase change temperature is 56-67°C, and there is no supercooling.

4. Recycling, high efficiency and environmental protection

• Small change in thermal characteristics, reusable, safe and non-toxic, non-flammable and explosive.

5. Reasonable cold storage time

• The cold storage time per unit mass is shorter than that of traditional cold storage agent, which greatly improves work efficiency.

Product information:

• 70 degree phase change materials (PCMs) are ideal for thermal management solutions. This is because they store and release heat energy during melting and freezing (transitioning from one phase to another).
• When this substance freezes, it releases a large amount of energy, in the form of latent heat of fusion or crystallization energy. On the contrary, when the material melts, the energy absorbed from the surrounding environment is equal when it changes from a solid to a liquid.
