Phase Change Energy Storage Material Temperature Control PCM Powder 15℃ PCM

Profile:

Phase change material (PCM) refers to a substance that changes its state and provides latent heat while maintaining a constant temperature. The process of transforming physical properties is called a phase change process, during which the phase change material will absorb or release a large amount of latent heat. The process of transforming a substance from one phase to another. The uniform part in a material system with identical physical and chemical properties and distinct interfaces with other parts is called a phase. Corresponding to the three states of solid, liquid, and gas, substances have solid phase, liquid phase, and gas phase. Our most common phase change material is water, which changes from liquid to solid (freezes) when the temperature drops to 0 ° C. When the temperature is above 0 ° C, water changes from solid to liquid (dissolved). During the freezing process, a large amount of cold energy is absorbed and stored, while during the dissolution process, a large amount of thermal energy is absorbed. The larger the quantity (volume) of ice, the longer the dissolution process takes. This is the most typical example of phase change materials.

Product Advantages:

• Stable performance and morphology: both before and after phase transition are solid, with no leakage issues
• High thermal conductivity efficiency: can release or accumulate cold energy in a timely manner, and can maintain a constant temperature inside the transportation box for a long time
• Accurate and balanced temperature control: Each area is at 5 ℃, without any supercooling phenomenon, so there is no need to worry about goods freezing
• Recycling, efficient and environmentally friendly: with minimal changes in thermal characteristics, reusable, safe and non-toxic, not flammable or explosive
• Reasonable cold storage time: The cold storage time per unit mass is shorter than traditional cold storage agents, greatly improving work efficiency
