METHOD FOR GENERATING THERMAL FLOW FROM A MAGNETOCALORIC ELEMENT AND MAGNETOCALORIC THERMAL GENERATOR

摘要

A method for generating a heat flow from a magnetocaloric element (1) comprising at least one magnetocaloric material (2) comprising a hot end (3) associated with a hot chamber (4) and a cold end (5) associated with a cold chamber (6), the method comprises magnetically and alternately activating and de-activating the magnetocaloric element (1) and circulating a heat transfer fluid through the magnetocaloric element (1) alternately towards the hot chamber (4) and the cold chamber (5) in synchronisation with the magnetic activation and de-activation phases. This method is characterized in that the method comprises reversing the direction of circulation of the heat transfer fluid during the magnetic activation and de-activation phases and also relates to a magnetocaloric heat generator implementing the method.
