Description

technical field [0001] The invention relates to a power generation device which converts the temperature difference energy of deep-sea hydrothermal fluid into electric energy. Background technique [0002] Deep-sea hydrothermal vents are generally distributed on the seabed at a depth of 2,000 to 3,000 meters. The maximum temperature of the hydrothermal fluid can reach 400°C, while the temperature of the surrounding seawater is only 2-4°C. The huge temperature gradient of the deep-sea hydrothermal area makes it contain huge The temperature difference energy, the heat flux of the global deep ocean mid-ridge hydrothermal area reaches 1.5~2.8TW. Effective use of these temperature difference energy to provide energy supply for deep sea exploration equipment has important scientific research value. At present, domestic and foreign studies on deep-sea hydrothermal temperature difference energy utilization devices have been carried out, but they are only at the theoretical stage, a...
