SOLAR HEAT COLLECTION TUBE
摘要:
A solar heat collection tube includes a center metal tube that allows a heat medium to flow therethrough, a glass tube that covers the outer circumference of the center metal tube to form an annular void between the glass tube and the center metal tube, and an absorber configured to absorb a difference in the thermal expansion between the center metal tube and the glass tube. The absorber has a connection cylinder and metal bellows. The metallic bellows are connected in series by the connection cylinder. The bellows are arranged to overlap in the radial direction with the connection cylinder located therebetween.
