Solar thermoelectric generation device

The invention discloses a solar thermoelectric generation device, including a base; a housing; a hot water inlet pipe and a hot water outlet pipe; a cold water inlet pipe and a cold water outlet pipe; a first cold water tank and a second cold water tank; a plurality of first coiled pipes; a plurality of second coiled pipes; and a plurality of thermoelectric generation assemblies. The first cold water tank and the second cold water tank are arranged under water, and the underwater depths of the first and second cold water tanks are increased gradually. The first coiled pipe has a mosquito coil-shaped structure formed by folding the metal pipe and winding the metal pipe, and the water inlet and the water outlet of the first coiled pipe are communicated with the hot water inlet pipe and the hot water outlet pipe. The second coiled pipe has a mosquito coil-shaped structure formed by folding the metal pipe and winding the metal pipe, and water inlet and the water outlet of the second coiled pipe are communicated w
