Abstract:
1. 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, the energy cell comprising: a housing means holding said phase change material (PCM), an insulating means arranged between said housing means, and said phase change material (PCM), a heat exchanging means encompassed by said phase change material (PCM) and comprising a number of pipe means, 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 a centrally located, flexible bladder means having a pair of open end parts which are fixed to said energy cell, and being flexible between said open end parts, wherein each of said pipe means comprises a heat transfer media, wherein said phase change material (PCM) encompasses said pipe means and said disc means and is 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), wherein said housing means comprises a cylinder block means, a cylinder head means, and a cylinder bottom means, wherein said cylinder head means comprises a first grommet means for each pipe means, and wherein said cylinder bottom means comprises a first grommet means for each pipe means, and wherein said energy cell also comprises a centrally located pipe provided with apertures, wherein a middle part of said centrally located pipe is arranged inside the bladder means.
