1. Heat exchange device through which there flow two fluids with independent circuits, a primary fluid (F1 ) exchanging with an intermittent heat source at the entry of the device, and a secondary fluid (F2 ) permitting the recovery of heat energy at the exit, the said primary fluid exchanging continuously with a heat-storage medium employing a phase-change material, the said medium acting as a constant temperature heat buffer during the phase change of the said material, characterized in that it comprises a stack of at least two exchange plates (8), each of which has a corrugation defining at least one continuous coil (9) so that the secondary fluid (F2 ) flows through the said exchange plates in series or in parallel, the said exchange plates (8) being furthermore separated by at least one perforated baffle (6, 10) allowing the primary fluid (F1 ) to flow in the interplate space left free by the storage medium employing a phase-change material (1, 13), the exchange of secondary fluid (F2 ) thus taking place simultaneously with the primary fluid (F1 ) and with the said storage medium, so that the said secondary fluid (F2 ) enables an essentially constant heat power to be obtained at the exit independently of the heat fluctuations of the primary fluid (F1 ). |
