PCM-Phase Change Material N-Heptadecane
N-heptadecane is an organic compound with a chemical formula of C17H36. It is a phase change material with the characteristic of phase change at a specific temperature.
The phase change temperature of n-heptadecane is between 29-31°C. When the ambient temperature exceeds its phase change temperature, n-heptadecane will change from solid to liquid and absorb a large amount of heat; when the ambient temperature is lower than its phase change temperature, n-heptadecane will change from liquid to solid and release a large amount of heat. This characteristic makes n-heptadecane have a wide range of application prospects in thermal energy storage and temperature regulation.
The phase change latent heat of n-heptadecane is high, about 220kJ/kg, which means that it can store or release a large amount of thermal energy during the phase change process. In addition, n-heptadecane has good thermal stability, stable chemical properties, and is not easy to decompose, so it has a long service life.
The application areas of n-heptadecane include solar thermal energy storage, building energy saving, cold chain logistics, electronic equipment heat dissipation, etc. In terms of solar thermal energy storage, n-heptadecane can be encapsulated in a solar water heater or a solar collector, absorbing solar energy and storing thermal energy during the day, and releasing thermal energy for home use at night. In terms of building energy conservation, n-heptadecane can be used to make intelligent thermostatic materials, which can automatically adjust the indoor temperature according to the changes in indoor and outdoor temperatures to achieve energy conservation.
It should be noted that n-heptadecane is a flammable substance, and fire safety should be paid attention to during use. In addition, the phase change temperature and latent heat of n-heptadecane will be affected by factors such as pressure and purity, so it is necessary to select and adjust according to specific circumstances in practical applications.
