The invention discloses a deep sea tubular temperature difference power generator, and belongs to the field of power generation equipment. The deep sea tubular temperature difference power generator comprises a main cavity, wherein the upper end and the lower end of the main cavity are provided with an upper support and a lower support respectively, and the upper support and the lower support arearranged in a hollowed-out manner; a plurality of mounting grooves for mounting temperature difference power generation sheets are formed in the periphery of the outer wall of the main cavity, each temperature difference power generation sheet and a corresponding heat conduction aluminum sheet are placed inside the corresponding mounting groove from inside to outside in sequence, and the temperature difference power generation sheets and the heat conduction aluminum sheets are fixed by using a high temperature glue; a heat dissipation piece which is in contact with each heat conduction aluminum sheet and is used for sealing the corresponding mounting groove so as to compress the corresponding heat conduction aluminum sheet and the corresponding temperature difference power generation sheetis mounted on the surface of the main cavity. The original disadvantages are overcome, the hot ends of the temperature difference power generation sheets cling to the main cavity, the cod ends of thetemperature difference power generation sheets cling to the heat conduction aluminum sheets, no gap exists fundamentally, and the efficiency of heat transfer is extremely high. The temperature difference power generation sheets are fixed and sealed by using the high temperature glue, the operation is simple, the cost is low, the structure is simplified greatly, the problem that the seal temperature and service life of an O-shaped ring are restricted is solved, and the stability and reliability of the device are improved.
Description
technical field [0001] The invention relates to a power generating device, in particular to a deep-sea tube type thermoelectric generator. Background technique [0002] Submarine hydrothermal vents serve as material and energy exchange windows between the crust and the ocean, and have high energy density. The heat flux of a typical hydrothermal vent can reach the megawatt level, and the temperature can reach 400 ° C. Therefore, the heat flux of hydrothermal vents Quantity measurement and utilization has always been the focus of global attention. The temperature difference between the hydrothermal fluid and the surrounding cold seawater can reach 300-400°C. Utilizing this green and renewable hydrothermal temperature difference energy can be used as an important energy supply method for ocean hydrothermal observation, and can provide megawatts of electric energy for seabed resource exploration and development, offshore platforms, and even offshore cities, which has great rese...
