A heat exchanger for a refrigerator comprises a refrigerant pipe part for forming a flow passage of refrigerant to make refrigerant condensed or evaporated; and a heat radiation paint which prevents corrosion of the refrigerant pipe and which is coated on the refrigerant pipe to increase the diffusion of heat generated by the refrigerant pipe. The heat radiation paint contains an anti-corrosion paint coated on the refrigerant pipe to prevent corrosion of the refrigerant pipe; and graphene mixed with the anti-corrosion paint to increase the diffusion of heat generated by the refrigerant pipe. The anti-corrosion paint contains 0.1 to 1.0weight% of the graphene based on 100weight% of the anti-corrosion paint. |
