Patent ID: 8037692

Claim:
A thermal generator ( 1 ) based on magneto-calorific material comprising: at least one fixed support ( 2 ) carrying at least two magneto-calorific thermal elements ( 3 ), magnetic means ( 4 ) being mobile in relation to the at least two thermal elements ( 3 ) so as to subject the at least two thermal elements ( 3 ) to a variation in magnetic field in order to make the temperature of the at least two thermal elements vary, and means for recovering the calories and frigories emitted by the at least two thermal elements ( 3 ) comprising at least two separate and distinct circuits ( 51 and 52 ), a first hot circuit ( 51 ) referred to as “hot” and a second cold circuit ( 52 ) referred to as “cold”, each circuit ( 51 and 52 ) being coupled to at least one heat exchanger ( 55 and 56 ) able to remove the calories or frigories recovered and fitted with means for switching ( 57 and 58 ) to put the corresponding thermal element ( 3 ) into the circuit ( 51 and 52 ), wherein each of the at least two thermal elements ( 3 ) has passages for fluid ( 35 ) forming at least two distinct collector circuits ( 31 and 32 ), a “hot” collector circuit ( 31 ) in which flows a heat transfer fluid of the hot circuit ( 51 ) whose function is to collect the calories emitted by the thermal element ( 3 ) subjected to the magnetic field, and a “cold” collector circuit ( 32 ) in which flows a heat transfer fluid of the cold circuit ( 52 ) whose function is to collect the frigories emitted by the thermal element ( 3 ) not subjected to the magnetic field, the heat transfer fluids moving alternately in one collector circuit to the other ( 31 and 32 ) depending on whether or not the thermal element ( 3 ) is subjected to the magnetic field and emits calories or frigories.
