Abstract
A conducting device, such as a corrugated fin, for a heat exchanger, has at least one surface with an increased microscopic roughness. A method increases the microscopic roughness of at least one surface of a conducting device such as a corrugated fin. A heat exchanger, such as an evaporator for an air-conditioning system of a motor vehicle, has tubes through which a medium flows and between which conducting devices are arranged, the conducting devices having a further medium, such as moist air, flowing around them.
