Internal condensation type CPC type vacuum tube semiconductor thermoelectric power generation device

The utility model aims to provide an internal condensation type CPC type vacuum tube semiconductor thermoelectric power generation device, which has the main advantages that solar energy is fully utilized, an external heat source is not needed, manual cooling is not needed, and higher temperature difference can be kept for a long time. The solar water heater mainly comprises a semiconductor temperature difference power generation module (29), a heat collection pipe (30), a water storage tank (31) and a stainless steel support (28). The light gathering plate (1) is arranged in the vacuum tube;a continuous heat source is provided for the hot end of the thermoelectric power generation module (29); the P/N type semiconductor thermocouple pair (6) penetrates through the three layers of glass from the interior of the vacuum tube and extends to the outer wall of the glass cover tube (14) to be connected with a cold end; the heat dissipation fins (21) attached to the outer surface of the glass cover pipe (14) take aw
