The invention discloses a device for executing thermoelectric power generation through memory
metal and belongs to the field of energy saving and environment protection based on small
temperature difference and small and medium-sized
new energy and waste-heat utilization. By adoption of the characteristics that the memory
metal is large in bending amount and high in
plasticity, can recover the previous shape at a memory temperature or above and the like, hot water
heat energy is converted into
mechanical energy by means of hydraulic power pushing through extension and extraction of blades, then the
mechanical energy is converted into
electric energy, the
kinetic energy link with the greatest energy losses is omitted and
electric energy conversion efficiency is improved. By the aid of the device, the defects in the
phase change and pressure change processes of traditional thermoelectric power generation are overcome, the problem of low heat efficiency happening due to the fact that deadsteam cannot be utilized in the traditional thermoelectric power
generation process is avoided, and the strict requirements on the aspects of working media, scales, sealing and the like are also avoided. The device for executing thermoelectric power generation through the memory
metal opens up a novel utilization approach for small-
sized small temperature difference heat sources and a new thoughtis provided for development and utilization of
solar energy,
geothermal energy and medium-low-temperature
waste heat.
