Modularized geothermal temperature difference thermovolt power generation device

The utility model relates to the technical field of geothermal power generation, in particular to a modularized geothermal temperature difference thermovolt power generation device. The system comprises a plurality of power generation groups, each power generation group comprises at least two thermal photovoltaic power generation modules, each thermal photovoltaic power generation module comprises a plurality of heat exchangers arranged at intervals, every two adjacent heat exchangers are a hot heat exchanger and a cold heat exchanger, and a plurality of thermoelectric modules used for thermal photovoltaic power generation are arranged between every two adjacent heat exchangers. The hot heat exchanger and the cold heat exchanger are connected with the cold water supply system and the hot water supply system respectively, and the flowing direction of hot water in the hot heat exchanger is opposite to the flowing direction of cold water in the cold heat exchanger. The power generation groups can be modularized,
