摘要： Heat exchanger comprising at least one tube (10, 10') for the circulation of a first fluid in a given direction (F1), and at least one heat exchange element (20) in the form of a corrugated surface, with generatrices substantially perpendicular to the direction (F1) in which the first fluid is circulated, said generatrices defining a direction (F2) of circulation of a second fluid inside the heat exchange element (20). According to the invention, the corrugated surface that forms the heat exchange element (20) at least partially exhibits a plurality of holes (21) arranged in a lattice structure. Application to motor vehicle engine cooling radiators, heater matrixes and air conditioning evaporators.
