Abstract

The invention relates to a heat exchanger (1), in particular oil-air cooler, for heat exchange between a first fluid (F1) and a second fluid (F2), having: at least a first row (R1) of tubular elements (2) and a second row (R2) of tubular elements (2), each for passage of the first fluid (F1), a flow channel (3) for the second fluid (F2) being formed between the first and second rows (R1, R2) of tubular elements (2); a collection vessel (4) at one end (ES) of the tubular elements (2); and a distribution vessel (5) at the other end (EV) of the tubular elements (2). Guiding elements (7) for guiding the second fluid (F2) extend along the flow channel (3) between the outer sides (2A) of adjacent tubular elements (2M, 2N) of the first and second rows (R1, R2) of tubular elements (2), said guiding elements (7) each having a plate part (8), the wall thickness (8W) of which is smaller than the largest cross-sectional dimension of the tubular elements (2) connected thereto. At least one adjustment device (30) is provided for adjusting the relative position of two guiding elements (7) about a pivot axis (31) running substantially in the direction of the longitudinal axes (L) of the tubular elements (2).
