Document Type and Number:
WIPO Patent Application WO/2018/186247
Kind Code:
A1
Abstract:
A solar heat collector that: has a plurality of vacuum tubes (21) that take in and use solar energy, are arranged lined up in the horizontal direction, and are arranged parallel to each other having a prescribed interval therebetween; and comprises a substantially planar reflective plate (22) that reflects solar light towards the opposite side of the plurality of vacuum tubes (21) to the sun. The reflective plate (22) has a reflective surface (24) having a saw-tooth cross-section at a location corresponding to between two adjacent vacuum tubes (21a, 21b). One surface of the saw teeth in the reflective surface (24) forms a first reflective surface (24a) that reflects solar light on to the lower vacuum tube (21a) out of the adjacent vacuum tubes (21a, 21b).
