The present invention relates to an energy cell (10) operable to generate a pressurized fluid for use as an energy source when a phase change material (PCM) changes from solid phase to liquid phase. The energy cell (10) comprises a housing means (12) holding the phase change material (PCM), and an insulating means (14) arranged between the housing means (12), and the phase change material (PCM). The energy cell (10) also comprises a heat exchanging means (16) encompassed by the phase change material (PCM) and comprising a number of pipe means (400), and a number of disc means (402, 404), each provided with a number of aperture means (500) and each encompassing a part of the pipe The energy cell (10) also comprises a centrally located, bladder means (410) which at its end parts are fixed to the energy eel! (10) and are open, and between the end parts being flexible. Each pipe means (400) comprises a heat transfer media. The phase change material (PCM) encompasses the pipe means (400) and the disc means (402, 404) and being able to pass through the aperture means (500). The bladder means (410) comprises a hydraulic fluid being able to flow in and out through the open end parts of the bladder means (410)3 and being affected by the phase change material (PCM).
An energy cell operable to generate a pressurized fluid for use as an energy source when a phase change material (PCM) changes from solid phase to liquid phase, said energy cell comprises a housing means holding said phase change material (PCM), characterized in that said energy cell also comprises an insulating means arranged between said housing means, and said phase change material (PCM), and a heat exchanging means encompassed by said phase change material (PCM) and comprising a number of pipe means, and a number of disc means, each provided with a number of aperture means and each encompassing a part of said pipe means, wherein there is a distance between two consecutive disc means, and in that said energy cell also comprises a centrally located, flexible bladder means which at its end parts are fixed to said energy cell and are open, and between said end parts being flexible, wherein each of said pipe means comprises a heat transfer media, and in that said phase change material (PCM) encompass said pipe means and said disc means and being able to pass through said aperture means, wherein said bladder means comprises a hydraulic fluid being able to flow in and out through said open end parts of said bladder means, and being affected by said phase change material (PCM).
