Thermal generator having a magneto-caloric material

Abstract

The present invention proposes a thermal generator which is non-polluting, has very good energy efficiency, is of simple and economical design and uses little energy, at the same time as being capable of further development, flexible and modular. In this thermal generator (), the thermal elements () composed of magneto-calorific material each comprises two separate collector circuits (and), a 'hot' collector circuit connected to a hot heat transfer fluid circuit () and a 'cold' collector circuit () linked to a cold heat transfer fluid circuit (). The heat transfer fluid is made to move alternately in one or the other of the collector circuits (and) depending on whether or not the thermal elements () are subjected to the magnetic field generated by the magnets () moving in rotation around a central axis (B) with respect to the thermal elements (). The heat transfer fluid circuits (and) are partly incorporated in a plate () carrying the said thermal elements () and connected to external circuits which have heat exchangers (and) using the calories and frigories generated by those thermal elements ().
