FIELD: power engineering.
SUBSTANCE: invention relates to power engineering and can be used in production of gas turbine engines (GTE), for example, aircraft. Air-liquid heat exchanger for heat exchange between air and liquid includes a set of parallel fins arranged relative to each other so as to form a passage for air circulation between them, wherein inside each fin there are three adjacent channels with two parallel partitions in each channel with the possibility of moving liquid flow in series from channel to channel with change of direction.
EFFECT: increased efficiency of heat exchange between cooled and cooling fluids.
