Heat carrier
First Claim
Patent Images
1. A heat carrier comprising:
- a closed container for accommodating therein a heating medium, said container having at least one heat receiving section and at least one heat radiating section, wherein said heating medium is transformed into a supercritical fluid when it is heated and undergoes convection due to a difference in temperature between said heat receiving section and said heat radiating section, thereby carrying heat from said heat receiving section to said heat radiating section;
wherein said container is a looped pipe connecting said heat receiving section and said heat radiating section;
wherein said looped pipe in said heat receiving section(s) has a planar mesh configuration; and
wherein said looped pipe has a smaller diameter in said heat receiving section(s) as compared with the rest of said pipe;
whereby a heat transfer between the heat receiving section and the heat radiating section is desirably balanced.

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.

12. A heat carrier comprising:
-
a closed container for accommodating therein a heating medium, said container having at least one heat receiving section and at least one heat radiating section, wherein said heating medium is transformed into a supercritical fluid when it is heated and undergoes convection due to a difference in temperature between said heat receiving section and said heat radiating section, thereby carrying heat from said heat receiving section to said heat radiating section;
wherein said container is a looped pipe connecting said heat receiving section and said heat radiating section;
wherein said heat receiving section is at a lower level than said heat radiating section; and
wherein said heat radiating section further includes a portion zigzagging between said heat receiving section and said heat radiating section. - View Dependent Claims (13)
