  • Patent number: 8701751
    Abstract: A heat exchanger for connecting thermal elements to one another and an external circuit in series, in parallel or according to a mixed configuration which limits the risk of leakage and the number of connections. The heat exchanger includes calorie-emitting and negative calorie-emitting thermal elements, and a conduit which passes through each of the thermal elements and has inlet and outlet orifices that are connected to one another and to at least one thermal fluid circuit by an interface plate. The interface plate includes two supply orifices and two discharge orifices for connecting the interface circuits to external hot and cold circuits for using the calories and the negative calories recovered from the thermal fluid.

  • Patent number: 8656725
    Abstract: A thermal generator (1) comprises at least one thermal flow generation unit (2) that is provided with at least one thermal module (3) each containing a magnetocaloric member (4) through which a coolant flows. A magnetic arrangement (9) is actuated for alternatively subjecting each magnetocaloric member (4) to a variation in magnetic field, the alternating movement of the coolant is synchronized with the magnetic field variation, the magnetocaloric member (4) is integrated into a closed flow circuit (6) that connects the two opposite ends (7) of the magnetocaloric member (4), and the closed circuit includes a single element (5) for moving the coolant through the magnetocaloric member (4).
