| description | The invention discloses a composite low-temperature phase-change cold storage material which is prepared from the following components by the weight percentage: 5%-7% of expanded graphite, and 93%-95% of n-hexanol. The composite low-temperature phase-change cold storage material is obtained by mixing evenly the expanded graphite and n-hexanol and then cooling to the room temperature. The cold storage material is in a semi-fluid state, can adapt to containers with different shapes, has no corrosiveness, and also does not easily generate leakage pollution problems; the cold storage material has high phase change latent heat, high thermal conductivity coefficient, appropriate phase change temperature, small degree of supercooling, and good charge/discharge cold circulation performance, and is applicable to a cold storage refrigeration car system; and the cool storage material has a few of components, allows the preparation method to be simple and easy to operate, has easily obtained raw materials, and is suitabl |
