- Regenerators are intended for use in devices in which gas circulation between a hot zone and a cold zone occurs.
- the structural properties of the regenerator are adapted to the conditions of use of the regenerator 1, such as the type of gas passing through it, the temperature of the hot and cold gas passing through it, the pressure of the gas as well as the dimensional constraints imposed by the device in which it must be integrated.
- regenerator 1 In general, the performance of regenerator 1 is linked to its ability to:
- a one-piece regenerator 1 comprising volumes of different porosities arranged along the direction of flow of the gases.
- a one-piece regenerator 1 comprising three portions PI, P2 and P3 having values of porosities PO1, PO 2 and P03.
- the regenerator 1, that is to say the walls 2 and the porous material 9 composing the portions 3 is of a in one piece.
- the material used is rigid and chosen according to the intended application. It has a Young module between 20 and 500 GPa.
- the PI portion is located on the side of the cold zone of the device and P3 on the side of the hot zone. During a thermodynamic cycle, the gases circulate from the hot zone to the cold zone and vice versa. Also, the concept of flow direction does not imply a concept of meaning in the present application.
- regenerator 1 is in one piece ensures that the overall porosity and the exchange surface of the regenerator are preserved over time.
- the one-piece nature of the regenerator 1 according to the invention makes it possible to overcome these effects, which allows it to maintain a porosity and a constant exchange surface over time. Its performance over time is therefore improved.
- the regenerator 1 can be used in any type of external heat supply device whether it is a motor, for the production of electricity for example, or a refrigerator for the production of cold.
- the characteristics of regenerator 1 are intimately linked to the conditions of use for which it is designed.
- the regenerator 1 is arranged so that the ends PI, P3 have the lowest porosity values so as to maximize the heat exchanges at the ends of the regenerator 1. This also makes it possible to maximize heat storage / destocking in the porous rigid material 9 constituting the parts PI and P3. This also makes it possible to store the majority of the heat in the part of the regenerator 1 situated on the side of the hot zone of the device.
- the porosity value of PO1 is different from the porosity value P03.
- P02 can be equal to P03 or POl, or be different from P03 and POl.
- the porosity value P03 is less than the porosity value PO1 which is less than P02.
- the difference in porosity between PO1 and P03 can, moreover, make it possible to introduce, and to control and / or modulate, a phase shift between the pressure and a gas flow rate, and / or a gas flow velocity profile.
- the porosity value PO1 is equal to P03, in this case the porosity value P02 is different from the value POl and P03.

Apart from the number of compartments detailed in the first and second variants, all of the characteristics of the regenerator according to the first aspect of the invention are shared with the third variant.
- This third variant makes it possible to further improve the performance of the regenerator 1 by varying the porosity values from one portion of the regenerator 1 to the other. Indeed, as mentioned above, limiting the thermal conduction of the regenerator 1 in the direction of gas flow improves the performance of the regenerator 1 and the efficiency of the device in which the regenerator 1 is intended to be integrated.
- this alternation of portions with high and low porosity aims to increase the overall hydraulic diameter of the regenerator 1 so as to reduce the overall pressure losses while retaining an equivalent exchange surface.
- the portions PI and P7 have high porosity values PO1 and P07 and greater than the porosity values P02 and P06 of the portions P2 and P6.

These operating parameters include, among other things, the type of gas, the pressures and temperatures of the gases as well as the operating frequency of the device in which the regenerator is intended to be integrated. Also, depending on the heat power to be exchanged required, the minimum exchange surface required will be known. Consequently, the size of the regenerator 1, the number of portions, the sizes and arrangements of the portions as well as the porosities of the portions will be arranged so that the hydraulic diameter, and therefore the pressure drops, are minimal.
- the hydraulic diameter of the flow channels present in the portions whose porosity is less than 1, extending along the regenerator 1 must be reduced to maximize the heat exchanges between the gas and the regenerator 1 but sufficiently low to do not introduce too high pressure drops.

- the geometry of the porous rigid material 9 of the regenerator 1 is adapted, in particular, by function of the operating frequency of the regenerator 1. Also, the geometry will be defined so that each portion 3 has a given porosity value and the smallest possible hydraulic diameter.
- the number of portions, the sizes and arrangements of the portions 3 as well as the porosities of the portions 3 are defined as a function of the geometry and of the other operating parameters.
