Definitions
- the present invention relates to a thermal generator comprising magnetocaloric elements, magnetic means arranged to alternately subject said magnetocaloric elements to a magnetic field variation and to create alternately in each magnetocaloric element a heating cycle and a cooling cycle, at least one coolant arranged to collect the calories and / or frigories produced by said magnetocaloric elements during the heating and cooling cycles, at least one hot exchange chamber and one cold exchange chamber provided respectively at the hot and cold ends of said generator, and means for circulating the coolant between said magnetocaloric elements and said exchange chambers, said generator comprising at least one thermal module comprising at least one set of N magnetocaloric elements.
- the magnetic cold technology has been known for more than twenty years and we know the benefits it brings in terms of ecology and sustainable development. Its limits are also known as to its useful calorific power and its efficiency. Therefore, research in this area all tend to improve the performance of such a generator, by playing on the various parameters, such as the magnetization power, the performance of the magnetocaloric element, the exchange surface between the heat transfer fluid and the magnetocaloric elements, the performance of the heat exchangers, etc.
- the publication US 4,829,770 relates in particular to the composition of the magnetocaloric elements and describes a heat generator using such elements and operating on the principle of Stirling engine.
- These fixed magnetocaloric elements are traversed by a heat-transfer gas, in particular nitrogen, the whole being contained in a tank animated with an alternating translational movement, synchronized with the magnetic field variation.
- Helium heat exchangers are connected to the hot and cold ends of the tank to transfer calories and frigories collected by the heat transfer gas to external circuits.
- the magnetocaloric elements are in the form of porous disks, stacked in the tank, separated from one another to delimit several chambers, or contiguous to one another to delimit two single chambers, according to the embodiment chosen.
- Each movement of the reservoir corresponds to a cold cycle or a hot cycle and causes a single direction of circulation of the heat transfer gas.
- the production cycles of calories and frigories are therefore alternating and not simultaneous.
- the heat-carrying power of a gas is significantly less efficient than that of a liquid.
- the exchange surface between the heat transfer gas and the magnetocaloric elements is also very limited. Given the very low operating temperatures, of the order of -200 ° C., the use of such a thermal generator is limited to laboratory applications. In conclusion, the calorific value of such a thermal generator is too low to find an industrial or domestic application.
- the publication WO 2005/093343 describes the principle of a magnetocaloric heat generator, using as heat transfer fluid the air to be heated or cooled of a motor vehicle.
- This solution provides that, in a startup phase, the refrigeration system operates in a closed circuit, the air being moved back and forth through the magnetocaloric element between a hot reservoir and a cold reservoir , by a piston and balance system, until reaching the desired temperature gradient.
- each movement of the piston corresponds to a cold cycle or a hot cycle and causes a single direction of flow of the air flow.
- the production cycles of calories and frigories are therefore alternating and not simultaneous.
- the exchange surface between the air and the magnetocaloric element is very low and does not allow to reach a calorific value sufficient for an industrial or domestic application, also taking into account that the coolant is not a liquid but a gas.
- WO 2007/026062 which belongs to the applicant, describes a magnetocaloric generator comprising two distinct collector circuits, namely a hot collector circuit and a cold collector circuit, hydraulically sealed with respect to each other, and each coupled to a collector circuit.

- the heat transfer fluid circulates in a closed loop in the collector circuits which comprise a part outside the generator and require at least one pump, switching means synchronized to the variation of the magnetic field, conduits and connectors.
- the present invention aims to solve this problem by proposing an industrial solution of a thermal generator of magnetocaloric material economically profitable, and modular to be easily configurable according to a specification given in the context of industrial as well as domestic applications . It also aims to simplify and rationalize the circulation of heat transfer fluid by eliminating the use of one or more hydraulic circuits.

- the pistons 40 are disposed adjacent in a circle about the central axis A, and form an annular structure. In the case of a linear thermal generator, the pistons would be aligned.

- these intermediate chambers 8 allow a mixing of the coolant between two successive thermal stages, the fluid passing from one thermal module to the other through the orifices 43 provided in the sleeve 42 of the pistons 40.
- This thermal stirring contributes to increasing the temperature gradient from one stage to another and, consequently, the temperature gradient between the hot and cold exchange chambers 6 provided at the ends of said generator.
- these intermediate chambers 8 may be sealed. In this case, the heat transfer fluid passes from one thermal stage to another only by the magnetocaloric elements 2.
- the stepped configuration as shown can of course be extended to thermal modules 10 to 13 having a linear structure.
