<p><P>PROBLEM TO BE SOLVED: To provide a solar thermal collector tube which increases heat collection efficiency by suppressing diffusion of energy transmitted to heat medium circulating in an inner tube. <P>SOLUTION: The solar thermal collector tube 1 includes: an inner tube 11 which receives sunlight collected by a collector mechanism 2 and transmits the energy to the heat medium 14 circulating internally; and an outer tube 12 with which the outer circumference of the inner tube 11 is covered to form a thermal insulating space 13. Here, a solar thermal absorption film 11a is applied on at least a part, which is irradiated with sunlight, on the surface of the inner pipe 11, and a heat reflective film 11b is applied on a part which is not irradiated with the sunlight from the collector mechanism 2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
