Thermal generator with magnetocaloric material and incorporated heat transfer fluid circulation means

Abstract

A heat generator () having at least one thermal module () that has N adjacent magnetocaloric elements () arranged in a circle around a central axis (A) and is subjected to a varying magnetic field caused by magnetic devices (). The magnetocaloric elements () are associated with N pistons () subjected to a reciprocating translation movement by an actuating cam () to circulate the heat transfer fluid, contained in the thermal module (), in two opposite directions, at the same time, so that a first fraction of the heat transfer fluid circulates towards a hot exchange chamber (), through the magnetocaloric elements () and is subjected to a heating cycle, and a second fraction of the heat transfer fluid circulates towards a cold exchange chamber (), through the magnetocaloric elements (), and is subjected to a cooling cycle, and inversely. The exchange chambers () are coupled with external circuits that use calories and frigories for heating, air-conditioning, tempering systems, etc.
