Abstract

PURPOSE:To prevent the cloud on the mirror surface, by arranging one end of the heat pipe on the reverse face of the mirror for traffic or near it and by burying the other end in the ground to transfer the subterranean heat. CONSTITUTION:After boring the hole in the ground for the purpose of burying heat pipe 7, metallic pipe 4 is fixed by concrete 5. Next, the mirror main body consisting of mirror 1, good conductor of heat 2, heat insulating materials 8a and 8b, and protection metallic materials 3a and 3b is bolted by fitting metal 6 and is fixed to metallic pipe 4, and the upper end part of heat pipe 7 is caused to adhere closely to good conductor of heat 2 on the reverse face of mirror 1. Further, after inserting heat insulating material 8c near the upper end part of heat pipe 7, one end 9b of protection covers 9 divided into halves is covered on the outside circumference of the upper end of metallic pipe 4 and is bolted, and flange part 9a at the other end is bolted to protection metallic material 3b and is fixed.
