Beschreibung
Zusammenfassung:	The invention discloses a low temperature phase change cool storage material for a refrigerator car, the low temperature phase change cool storage material includes ethylene glycol and n-heptanol, wherein, the mass ratio of ethylene glycol and n-heptanol is 10-35:90 - 65, the low temperature phase change cool storage material is good in stability, not easy to decompose, safe and non-toxic, and low in cost. By the optimum combination of expanded graphite / ethylene glycol / n-heptanol, the latent heat is 102kJ / kg, the phase transition temperature is-43.3 DEG C, and the expanded graphite / ethylene glycol / n-heptanol phase change cool storage material has a density of 0.68g / cm , the thermal conductivity of 0.8357 W / m * K, and the specific heat capacity of 529 J / kg * K.
