Energy cell for converting heat into other forms of energy and apparatus for the recovery of heat that makes use of such an energy cell

摘要

Energy cell that is provided with a pressure vessel (2) with two chambers separated by a membrane, respectively a first chamber (6) filled with a phase-change material (23) and a second chamber (7) filled with hydraulic fluid (24), whereby this energy cell (1) is provided with means to be able to heat and cool the phase-change material (23) alternately, coupled with a volume change, whereby the second chamber (7) is provided with a passage (26) that acts as an input and/or output for the hydraulic fluid (24), whereby the membrane (5) is stretched elastically upon a phase change whereby the volume in the first chamber (6) increases.
