The invention discloses a seafloor
hydrothermal vent temperature difference energy power generating device. The seafloor
hydrothermal vent temperature difference energy power generating device comprises a flow
guide tube and a cavity; a top end cover and a
flange end cover are fixed to two ends of the cavity respectively; the flow
guide tube, the top end cover, the
flange end cover and the cavity form a sealed cavity; a first
temperature difference power generating sheet, a separation board and a second temperature difference power generating sheet are arranged in the sealed cavity; the hot ends of the first temperature difference power generating sheet and the second temperature difference power generating sheet are attached to the outer wall of the flow
guide tube; the cold ends of the first temperature difference power generating sheet and the second temperature difference power generating sheet are attached to the inner wall of the cavity; the exterior of the cavity is provided with a plurality of ring ribs; and the lower end of the flow guide tube is provided with a flow guide tube
flange and a trumpet-shaped flow separation hood. According to the seafloor
hydrothermal vent temperature difference energy power generating device of the invention, a thermoelectric Seebeck effect is utilized, and the flow guide tube is adopted to guide hydrothermal fluid, and the temperature difference power generating sheets are adopted to convert
heat energy into
electric energy, and therefore, power generation can be realized. The seafloor hydrothermal vent temperature difference energy power generating device of the invention is simple and compact in structure; and the temperature difference of the two ends of each temperature difference power generating sheet is large, and therefore, the
utilization rate of hydrothermal energy is high.
