| 摘要 |
The invention relates to a counter-current dual-flow air/air exchanger (1) comprising a first network of channels oriented along a longitudinal axis (X-X') of the exchanger (1), suitable for causing a first airflow (F1) to flow in a first direction, and a second network of channels oriented along the longitudinal axis (X-X') of the exchanger (1), suitable for causing a second airflow (F2) to flow in the direction opposite to the first airflow (F1). The exchanger (1) includes devices (10, 12, 14) for reversing the flow direction of the second airflow (F2) in the second network of channels, in such a manner that the first and second airflows (F1, F2) flow in opposite directions, suitable for protecting the exchanger (1) against ice. |
