| 摘要 |
The invention concerns a tube (1) internally divided into two longitudinal channels (16) by a median spacer (9). In an end zone (4) penetrating a fluid box (19), the tube is deformed so as to be widened in its transverse section and shortened on either side of the spacer in the direction thereof. The space requirement of the fluid box in the longitudinal direction of the transverse sections of the tubes, and consequently the space requirement of the whole heat exchanger, can thereby be reduced relatively to the maximum space requirement of the array formed by the tubes and the separators (5) stacked therewith. The invention is applicable to cooling radiators of engines powering motor vehicles.
