摘要 |
The invention relates to a heat exchanger for the exchange of heat between first and second fluids. The heat exchanger includes first circulation canals for the circulation of the first fluid in a first direction of circulation (D1), and second circulation canals for the circulation of the second fluid, and perturbation walls arranged in the second circulation canals for the second fluid and having perturbators that perturb the flow of the second fluid. The perturbation walls respectively have at least one dividing rib. The at least one rib extends in a second direction (D2) substantially perpendicular to the first direction in which the first fluid circulates, and over a predefined distance of the wall that is less than the total width of the wall in the second direction, so as to define at least two circulation passes for the second fluid substantially perpendicular to the circulation of the first fluid.
