Solar heat collecting apparatus and solar power generation system

摘要

According to one embodiment, a solar heat collecting apparatus (1) comprises a first heat exchanging unit (22a) and a second heat exchanging unit (22b). The first heat exchanging unit includes a first pipe through which a heat medium flows (23) and a first heat receiving face which receives heat of sunlight reflected by a plurality of reflecting units (10). The first heat exchanging unit heats the heat medium flowing through the first pipe by using heat of the first heat receiving face. A second heat exchanging unit includes a second pipe through which the heat medium heated by the first heat exchanging unit flows, a second heat receiving face which receives heat of the sunlight reflected by a plurality of reflecting units, and a nozzle provided to the second pipe to discharge the heat medium flowing through the second pipe toward a back face of the second heat receiving face.
