Abstract
Submarine hydrothermal vents are the exchange channels of substance and energy between the oceans and the crust. The enormous heat flux caused by seafloor hydrothermal activities has great influence on the geologic and biological environment of hydrothermal zones, and even global climate. In order to achieve long-term observation of submarine hydrothermal vents, thermoelectric power generation technology emerged to power the observation equipment in recent years. In this paper, an experimental platform was built for the thermoelectric generator (TEG), and the key performance parameters of the TEG were tested under pressure. Based on the test data, a new plate-type thermoelectric power generation module was designed for shallow-sea hydrothermal vents. A vacuum and single-sided film structure was developed to reduce the relevant structural thickness, thermal resistance and the overall weight of the module, and to increase the contact quality and overall energy conversion efficiency. Then discussion was performed about how to optimize it for the application to deep seas. Finally, the pressure and performance tests of the module structure were performed successfully.
