A thermochemical reactor (1) for a cooling and/or heating includes at least one reagent unit (2) which, using chemical combination, can absorb a gas stream originating from a tank and which, using the reverse chemical reaction, can desorb the gas stream due to a rise in temperature. The reagent unit (2) is disposed in a container (3) that has walls, at least some of which are equipped with diffusers (7) for distributing the gas stream. In addition, the reagent unit (2), which can be heated, is of the type that can expand during absorption of the gas stream and retract during desorption of the gas stream. Moreover, at least some of the walls are mobile walls, which can accompany the longitudinal movement of the reagent unit (2), to enable successive deformation phenomena.

1. Thermochemical reactor for a cooling and/or heating apparatus comprising: a tank for containing a gas,at least one reagent unit capable of absorbing, by chemical combination, a gas flow coming from the tank and of desorbing the gas flow by reverse chemical reaction, under the action of a rise in temperature, so that the gas flow reintegrates into said tank,a container connected to said tank through a pipe, said reagent unit being arranged in said container, said container having walls, at least some of which include diffuser means permitting to distribute the gas flow in one direction or in the other one between the reagent unit and the tank,heating means to which said reagent unit is connected,wherein said reagent unit is formed of a material that expands during the absorption of the gas flow and retracts during the desorption of the gas flow,wherein the walls of the container include(i) a tube within which the reagent unit is introduced without radial play in a radial direction of the tube, an outer radial surface of the reagent unit being in close contact with an inner radial surface of the tube in a radial direction of the tube, so that the reagent unit performs movements in a longitudinal direction of the tube during its expansion and its retraction inside said container, and(ii) movable walls between which the reagent unit is sandwiched, wherein each of the movable walls has an internal face oriented transversally with respect to the longitudinal direction of the tube and is movable within the tube along a longitudinal direction of the tube, the respective internal faces of the movable walls being applied against and integral with respective opposite end faces of the reagent unit in a longitudinal direction of the tube, so that the movable walls move in the longitudinal direction of the tube following the movements performed by the reagent unit in the longitudinal direction of the tube during its expansion and its retraction inside said container,so as to enable the successive deformation phenomena by expansion and restoring to the initial shape by retraction of said reagent unit. 2. Reactor according to claim 1, wherein the container is defined by the tube, each end of which is extended by closing means in the form of at least one half-sphere and the diameter of which is such that the tube allows inserting substantially without backlash the reagent unit, which has, in turn, a cylindrical shape and is sandwiched between the movable walls defined by two discs capable of sliding longitudinally, should the case arise, towards each closing means under the action of the expansion of the reagent unit, or, should the case arise, towards the central zone of the tube under the action of the retraction of the reagent unit. 3. Reactor according to claim 2, wherein the discs have a diameter identical to the inner diameter of the tube defining the container, and are thus capable, each, of abutting against the inner wall of one of the closing means, in order to stop the movement performed by the reagent unit during expansion of the reagent unit and to prevent the reagent unit from entering into contact with the bottom of each closing means. 4. Reactor according to claim 2, wherein the discs are applied against one of lower or upper faces, respectively, of the reagent unit. 5. Reactor according to claim 1, wherein the diffuser means enabling the distribution of the gas flow in one direction or in the other one between the reagent unit and the tank are defined by a set of several walls imbricated into each other, delimiting centrally a channel, each made out of materials capable of permitting the passing through of the gas flow, said set being capable of being inserted through openings provided for this purpose in said reagent unit and said movable walls, and said set communicating at the level of one of its ends with the pipe connecting the container to the tank. 6. Reactor according to claim 5, wherein a set of several walls has a length identical to that of the tube defining the container, so that each of ends of said set enters into contact with the bottom of each of the closing means. 7. Reactor according to claim 1, wherein the heating means are defined by a set of heating collars or ribbons positioned outside the container. 8. Cooling and/or heating apparatus comprising a thermochemical reactor according to claim 1 connected to a gas-fluid tank by means of a pipe provided with a valve. 9. Isothermal device equipped with a cooling and/or heating apparatus according to claim 8. 10. Reactor according to claim 1, wherein the mobile walls are entirely within the tube.
