ABSTRACT:
A solar heat collecting apparatus wherein a heat-absorbing plate for absorbing the solar radiation is installed in a vacuum vessel, the solar heat accumulated in the heat-absorbing plate is transmitted to a working medium in a pipe connected to the heat-absorbing plate, an upper surface layer for passing the solar radiation irradiated on the heat-absorbing plate therethrough and reflecting the infrared radiation emerging from the heat-absorbing plate is formed on the upper surface of the heat-absorbing plate, a lower surface layer for reflecting the infrared radiation emerging from the heat-absorbing plate is formed on the lower surface of the heat-absorbing plate, a space-diving film is formed between the lower surface of the heat-absorbing plate and the bottom surface of the vacuum vessel, a reflection layer is formed on the bottom surface of the vacuum vessel, a film for passing the solar radiation and reflecting the infrared radiation is provided between the upper surface of the heat-absorbing plate and the upper wall of the vacuum vessel, and the upper wall of the vacuum vessel is formed of a plurality of transparent curved segments.
