摘要: An air fin for a heat exchanger has air channels defined by corrugations, the corrugations having generally planar flanks joined by alternating crests and troughs. Perforations extend through portions of at least some of the flanks and are aligned within two spaced apart planes. A rectangular aperture extends through at least two consecutive ones of the corrugations, and is bounded by the two planes. A method of making the air fin includes forming perforations into a continuous strip of metal sheet at regular intervals, corrugating the strip to form crests and troughs between the perforations, and punching out a portion of the strip at regular intervals. The punching out includes shearing webs between the perforations, and results in the formation of the rectangular aperture.
