The present invention relates to a compact, multipurpose magnetocaloric thermal generator with high heat yield, having a maximum heat exchange coefficient, while being easily industrializable and having a modular configuration in order to meet the needs of a broad range of industrial as well as household applications. The thermal generator (1) is characterized in that it comprises at least one thermal module (10) having a plurality of thermal elements (40), stacked and arranged to define between them channels for the circulation of heat transfer fluid, distributed in hot channels in which the heat transfer fluid from the hot collector circuit circulates and in cold channels in which the heat transfer fluid from the cold collector circuit circulates, the hot and cold channels being alternated between said thermal elements (40), and in that said thermal elements (40) include fluid intake and outlet orifices that communicate with each other in such a manner as to distribute the flow of the heat transfer fluid from each hot and cold collector circuit respectively in the respective hot and cold channels. Applications: Heating, tempering, air conditioning, refrigeration in any industrial or household facility.

La présente invention concerne un générateur thermique magnétocalorique compact et polyvalent, à fort rendement calorifique, ayant un coefficient d'échange thermique maximal, tout en étant facilement industrialisable et en ayant une configuration modulaire pour pouvoir répondre à une large gamme d'applications aussi bien industrielles que domestiques. Le générateur thermique (1) est caractérisé en ce qu'il- comporte au moins un module- thermique (10) constitué d'une pluralité d'éléments thermiques (40), empilés et agencés pour délimiter entre eux des canaux de circulation du fluide caloporteur, répartis en canaux chauds dans lesquels circule le fluide caloporteur du circuit collecteur chaud et en canaux froids dans lesquels circule le fluide caloporteur du circuit collecteur froid, les canaux chauds et froids étant alternés entre lesdits éléments thermiques (40), et en ce que lesdits éléments thermiques (40) comportent des orifices d'entrée et de sortie de fluide qui communiquent entre eux de manière à répartir le débit du fluide caloporteur de chaque circuit collecteur chaud et froid respectivement dans les canaux chauds et froids correspondants. Applications : Chauffage, tempérage, climatisation, réfrigération dans toute installation industrielle ou domestique.
