Abstract
A heat carrier comprises a closed or looped heat pipe having a heat receiving section and a heat radiating section, and accommodating therein a heating medium such as carbon dioxide, which becomes a low-viscous supercritical fluid when it is heated. The supercritical fluid is circulated in the heat pipe by convection due to a density difference based on a temperature difference between the heat receiving section and the heat radiating section, thereby carrying heat from the heat receiving section to the heat radiating section.
