Embodiment

Some magnet is (as the magnetic temperature inductive switch of electronic pot, cook with about 102 ℃ magnet, insulation is used and is about 72 ℃ magnetic reed switch) when being heated above Curie temperature (ferromagnetism becomes paramagnetic temperature), to lose magnetism, otherwise be cooled to below the Curie temperature and can recover magnetic gradually again, therefore we are wrapped with winding with an iron core and are heated to and place this magnet top more than the Curie temperature then, when enough close, magnet will by magnetic force push away toward iron core move and make the distance near more, magnetic force is stronger again and make magnet shake to iron core, the coil of this moment will induce a pulse voltage electric current because of increasing suddenly by magnetic flux in the iron core of coil, and we with this pulse through rectification and to charge in batteries, obtain a charging unit, and when magnet touches iron core, will be by iron core and heat-conductive assembly heating [heat conduction] to more than the Curie temperature and loss of excitation, when magnet to the magnetic force of iron core less than gravity and spring tension and, magnet will be pulled on the radiating subassembly by spring, the radiating subassembly cooling [heat conduction] that magnet will be cooled off in advance when touching radiating subassembly is to Curie temperature, and reply magnetic gradually, until magnet to the magnetic force of iron core greater than gravity and spring tension and, and magnet shaken produce the charging pulse of another time to iron core, so again and again always to battery charge, disappearing or cool off up to thermal source badly just can decommission, and promptly resumes operation voluntarily again if cold and hot condition is replied [heat temperature greater than Curie temperature greater than cold temperature].When improving heat source temperature or reducing bottom temp, to make the interval of pulse shorten and the increasing mean charging current, and shortened cooling time but the pulse current reduction the closer to magnet iron core, suitable distance also can promote generating efficiency, and dwindle the Cooling and Heat Source temperature difference of normal operation, charging voltage then can be determined by wire circle, because the coil pendulum is at thermal source, even interior ohmic loss is arranged, energy still returns thermal source, therefore setting coil is the volume that principle effectively reduces coil can not damage, use the device number that promotes space, the function of spring is the position and the direction of fixed magnets, and magnet when reducing to a certain degree, magnetic force just is returned to cool position, also can reduce with spring location and to slide or friction partly can reach higher useful life in the hope of device, using the relative cost that reduces device, and cooperating heat conducting temperature-time difference can make magnet in the shorter time, produce loss of excitation with the multi-disc combination magnet or time magnetic is raised the efficiency.

Moreover, the temperature magnetic properties curve of magnet itself is then concerning the generating efficiency of whole group of mechanism, the occasion that the Curie temperature of magnet then must be used, the median that generally is about the Cooling and Heat Source temperature, the magnetic pole guiding (N-S) of magnet is ground into nano level unit magnetic moment with ferrimagnet, lures that with external magnetic field magnetic moment is arranged in the mode that we want into again, and sintering forms again after adding press fit, the Curie temperature of magnet is then according to material and impurity addition manner and become, and this is a material source.And with unit device downsizing, the time difference hot residual and hot transmission that also can effectively reduce magnet is improved the conversion efficiency of device.
