DEVICE FOR RECOVERING AND CONVERTING HEAT ENERGY INTO ELECTRICAL ENERGY

摘要

The invention relates to a device for converting heat energy into electrical energy, comprising cells (C1, C2) including: a cavity (2), a wall (2.1) of which is to be in contact with a heat source (SC); a cavity (4), a wall (4.1) of which is to be in contact with a cold source (SF); a primary channel (6) between the cavity (2) and the cavity (4), which conveys a fluid in the form of liquid drops, the primary channel comprising a means for conveying drops of a liquid fluid from the cavity (4) to the cavity (2); at least one secondary channel (8) between the cavity (2) and the cavity (4), which conveys the fluid in the form of a gas; a piezoelectric material (10) arranged in one of the cavities (2) and (4); and a fluid in the form of a liquid and gas confined in the cell.
