Power Generation Performance

In order to obtain the power generation of the thermoelectric power generator (TEG) group, a similar structure of the disc sandwich structure and an experimental system are built to analyze the power generation performance and temperature characteristics. To improve heat transfer and move heat from the hot side to the cold side, heat pipes with high thermal conductivity are arranged on the adjacent cold and hot plates of the TEG. The similar sandwich structure has 17 cold plates and 17 hot plates for the TEG pieces, which are connected in series on the circuit. Working conditions are hot air flow and cold water flow; hot air temperature and cold water temperature are set to a fixed temperature. The power generation of a single TEG is tested for verifying linear changes in the power generation performance with temperature differences (Td). Experimental results are that the power generation is improved by the air flow and water flow increasing. The water flow has a smaller effect on the power generation than the air flow. In the cold side of TEG pieces, the temperature of the cold side showed a gradual upward trend, the temperature of the hot side showed a wave trough phenomenon, and the Td showed a wave trough phenomenon. The hot air flow and the cold water changing cannot weaken the temperature trend of the hot side and the cold side. The hot air flow can more significantly increase the Td than the cold water.

The target of our present research is to develop a river monitoring instrument equipped with electricity power generator to supply for its own demand by utilizing energy of flow of the river. To apply this instrument to natural river, its generator should be simple, small and durable with wide flow velocity range of operation. In this paper, the vibration induced by the trailing vortex (T-VIV) on a cruciform circular-cylinder/strip-plate system is firstly introduced compared with the well-known Ka´rma´n vortex excitation (K-VIV). Secondly, a design for a generator utilizing the T-VIV is presented. Thirdly, an estimation technique for electricity power extracted from the vortex induced vibration (VIV) and a design guide for power generation module obtaining the maximum power are proposed. Finally, using the estimation technique to the T-VIV in air, an estimation of oscillation behavior and power generation performance of an T-VIV generator module applied to water flow are presented.

Thermal fluids are served to give the greater ΔT to the thermoelectric (TE) junctions. For the larger power generation using a limited number of modules and the limited amounts of thermal fluids, the multi-layered TE panels can save the occupied space effectively. Because the temperatures of the fluids vary along the planer TE panels due to heat exchange through the panels, the directions of fluids is important to obtain the larger output power, P, from a TE power generator. The methods to stack a few long planer TE panels and to determine the fluid directions are mathematically studied from the steady-state heat exchange. P for various kinds of fluid directions are calculated. P commonly shows the maximum against the panel length because of the balance between the internal resistance and ΔT. This maximum of P can be further maximized by choosing the counter flow. The non-dimensional analysis predicts that two fluids should flow in counterwise. When two series of fluids are used, the circulation method is another key issue for the optimal TE design.

The unique merit of the implantable thermoelectric generator lies in its direct utilization of the temperature difference intrinsically existing throughout the whole biological body. Therefore, it can resolve the service life mismatch between the IMD and its battery. In order to promoting the TEG maximum power, a piece of radioisotope fuel was fixed on the TEG hot junction. Recurring to the thermal energy released during disintegration of radioactive isotope, it can guarantee a marked promotion in the temperature difference across the implanted TEG; consequently apply enough power for the IMDs.
