<p><P>PROBLEM TO BE SOLVED: To increase a temperature of a heat collecting pipe to improve the efficiency of heat collection, and to suppress a heat leak rate. <P>SOLUTION: A solar heat collector 14 includes: a mirror 20 for condensing solar light P; the heat collecting pipe 21 arranged facing to the mirror, for absorbing the solar light condensed by the mirror to collect heat thereof, and for heating a heating medium R1 flowing inside; and a translucent glass tube 35 for containing and insulating the heat collecting pipe in a vacuum state. In a vacuum space 37 between the heat collecting pipe 21 and the glass tube 35, a radiation shield 36 is arranged in a region opposite to a region facing to the mirror 20. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
