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.

A number of vanes 12 are disposed in a peripheral direction of a plurality of supporting disks disposed along a rotary shaft 14 at given intervals. Each vane 12 is disposed at an angular interval as determined by a logistic representation. Thereby the intensity and variations of noise levels at around 8N on the low-frequency side, as well as the noise level caused by rotary first-order sounds, can be reduced.
