Abstract

The invention relates to a storage heat exchanger ( 12, 12 ′) including at least one first flow tube ( 25 ) and one second flow tube ( 25 ) for a heat transfer fluid that respectively include a first end ( 26 ) leading into a first manifold ( 27 ) and a second end ( 28 ) leading into a second manifold ( 29 ), the first and second flow tubes ( 25 ) being placed adjacent to one another. The storage heat exchanger also includes at least one insert ( 30 ) positioned between the first flow tube ( 25 ) and the second flow tube ( 25 ), the insert ( 30 ) consisting of a plurality of blades ( 31 ) comprising a first edge ( 32 ) contacting the first flow tube ( 25 ) and a second edge ( 33 ) contacting the second flow tube ( 25 ), at least one interstitial space ( 35 ) being defined between the insert ( 30 ) and the flow tubes ( 25 ). The interstitial space ( 35 ) is filled with a material for storing calories or frigories.
