Ocean temperature difference energy power generation is to generate power by utilizing the temperature difference of the sea water in the shallow layer and the deep layer. The data show that the temperature difference between the normal temperature sea water and the cold sea water is more than 20 ℃, and pure electric power can be generated. The temperature of the surface sea water of the tropical and subtropical areas of the earth can reach 65 ℃, cold sea water is extracted from the deep sea, and the temperature is generally 4-5 ℃, so that the sea water thermoelectric power generation prospect is quite considerable. At present, the traditional ocean temperature difference power generation mode takes shallow sea water as a heat source, evaporates a low-boiling point working medium of a closed circulation system into gas, and pushes a turbine to rotate for power generation; the deep sea water is used as a cold source, the boiling steam working medium is condensed into liquid, and the circulating flow of the working medium in the system is realized by pushing a working medium pump. The temperature difference power generation in the form needs a low-boiling-point working medium, and the loss of the working medium caused by long-term use is unavoidable; and the pump for pumping deep and shallow seawater and pushing working medium to circularly flow consumes electric energy in the system, thereby reducing the power generation efficiency of the system.
