Abstract

The invention relates to a solid-liquid phase change heat storage type power generation testing device and a working method thereof, and belongs to the technical field of ocean temperature difference energy power generation. The solid-liquid phase change heat storage type power generation testing device comprises an energy accumulator, a solid-liquid phase change heat exchanger, a water pool, an oil bag, an electromagnetic reversing valve, a hydraulic motor, a power generator and an acquisition card. According to the power generation testing device, through a phase change material, by using the change of external water temperature, heat energy in the environment is collected to complete conversion from temperature difference energy to hydraulic energy, the hydraulic energy drives the hydraulic motor to rotate and drives the generator to rotate, conversion from the hydraulic energy to electric energy is achieved, the electric energy generated by the generator is stored in the battery, and energy conversion and storage are completed. The change of the seawater temperature along with the depth is simulated by changing the external water temperature, and the problem of the ocean temperature difference energy power generation test technology is solved.

Description

technical field [0001] The invention relates to a solid-liquid phase change heat storage type power generation test device and a working method thereof, belonging to the technical field of ocean temperature difference energy power generation. Background technique [0002] Ocean temperature difference energy refers to the ocean thermal energy stored in the form of the temperature difference between the surface and deep seawater, and its main source of energy is the solar radiation energy stored in the ocean. Thermal power generation refers to the use of seawater temperature difference to generate electricity. The temperature difference between different water layers in the ocean is very large. In the case of the South my country Sea, the surface water temperature is about 25°C. With the increase of seawater depth, the seawater temperature gradually decreases. At a depth of 500 meters, the seawater temperature is about 10°C. . [0003] At present, there are two main forms of ...
