The heat recuperation device (1) for an exhaust line comprises: - a valve body (7) having at least one exhaust gas inlet (9) and at least one exhaust gas outlet (11); - a shutter element (15) able to move at least between a position of blocking off a cutoff section of the path (13) along which the exhaust gases pass and an uncovering position. The valve body (7) has an inlet zone (35) situated between the inlet (9) and the cutoff section and an outlet zone (37) situated between the cutoff section and the outlet (11), the device (1) further comprising a plurality of heat-exchange tubes (43), each tube (43) having an upstream end (45) connected directly to the inlet zone (35), a downstream end (47) connected directly to the outlet zone (37), and at least one curved portion (49) between the upstream and downstream ends (45, 47). |
