HEAT GENERATOR WITH MAGNETOCALORIC MATERIAL Russian patent published in 2013 - IPC F25B21/00 

FIELD: heating.

SUBSTANCE: heat generator includes at least one thermal module (10) that contains N adjacent magnetocaloric elements (2) located around the central axis (A) and subject to magnetic field oscillations caused with magnetic devices (3) so that it leads to their temperature difference. Those magnetocaloric elements (2) are connected to N pistons (40) subject to back-and-forth movement by means of drive cam (70) for the purpose of circulation of liquid heat carrier contained in thermal module (10), in two opposite directions simultaneously so that the first fraction of liquid heat carrier can circulate in direction to heat exchange chamber (5) through magnetocaloric elements (2) subject to a heating cycle, and the second fraction of liquid heat carrier can circulate in direction to cold exchange chamber (6) through magnetocaloric elements (2), which are subject to a cooling cycle, and vice versa. Exchange chambers (5, 6) are connected to external outlines that use calories and frigories for such operations as heating, air conditioning, and humidification of the system.

EFFECT: simplifying rationalisation of a liquid heat carrier circulation path.
