摘要： The present invention relates to a heat transport medium used in a heat exchanger; wherein the heat transport medium improves heat conductivity without increasing kinetic viscosity by stably dispersing carbon nanotubes in a base liquid; especially water and ethylene glycol. Carbon nanotubes are stably dispersed in the base liquid by including sodium carboxyl methyl cellulose which has average molecular weight given by GPC measuring method is 6000-30000. Therefore, the heat transport medium improves heat conductivity without increasing kinetic viscosity. pH can be kept in proper range. Furthermore, a chemical reaction by the dispersant is prevented.
