TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: In the internal quartz array solar photo-thermal converter, the quartz thermal absorbing device at least comprises one of: (a) a blind tube quartz thermal absorbing device; where one end of the blind tube quartz thermal absorbing device is a blind tube while the other is open; a same light transmission device is arranged outside the blind tube quartz thermal absorbing device; the fluid flows out from an inlet and an outlet of a quartz tube; and a solar coating is arranged inside or outside a partial shell in the middle of the quartz device; (b) a quartz thermal absorbing device comprising at least one inlet and an outlet; where a light transmission device is arranged outside the quartz thermal absorbing device; a solar coating is arranged between the inlet and the outlet of the quartz part; a fluid enters via the inlet and flows out after reaching the outlet; and the fluid exchanges heat with the thermal energy converted from the solar energy in the part; and (c) a quartz thermal tube thermal absorbing device; where the quartz tube is manufactured into a thermal tube; a light transmission device is arranged outside the quartz tube; and the shell of an evaporating end of the quartz thermal tube is equipped with a solar coating. The solar coating is at least one or combination of: (a) metal and metal oxides comprising silver, copper, and aluminum sesquioxide; (b) polymer; (c) nanometer materials comprising zinc oxide nanometer; (d) adhesive; (e) coating formed by single metal; and (f) solar multi-layer selecting coating. The part of the chamber and/or the thermal absorbing device where the sunlight cannot be irradiated is also equipped with a thermal insulating material, which is at least one or combination of: (a) metal or non-metal material containing a vacuum layer (1); (b) asbestos and fiber thermal insulating material; (c) thermal insulating cement; (d) polyurethane, polyphenyl material, plastic and nylon thermal insulating material; and (e) thermal insulating material.
