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.

A metal roof panel includes a rib with a unique shape. The rib is bilateral with upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex. Between each rib is a channel, preferably including at least one raised surface. The lower surface of the channel between the raised surfaces, and the top of the raised surfaces, are substantially planar and parallel to the flat surface of the apex of the panel. A unique method of manufacturing the roof panel employs a roll machine configured to shape a piece of sheet metal into the roof panel by modifying the shape in many small increments, which allows the final product to have a fairly intricate bend pattern.

Projection row (2) and recess row (3) are alternately and successively formed in a direction (Y-direction) perpendicular to a direction (X-direction) of their rows, thereby forming a corrugated cross-sectional shape of a cross-sectional wave shape. Between projection row (2) and recess row (3), there is provided inclined wall surface (4) having a wave shape in plan view. Each of projection row (2) and recess row (3) has a shape in a cross-section along X-direction that is formed into a corrugated cross-sectional shape of a wave shape. Pitch and height difference between valley portion (5) and crest portion (6) in the corrugated cross-sectional shape along this X-direction are smaller, as compared with a relationship between projection row (2) and recess row (3) in the corrugated cross-sectional shape along Y-direction. The corrugated metal plate of such shape has advantages that machining for making cross-sectional shapes in two directions of X and Y into wave shapes is easy and that the flexural rigidity difference between two direction of X and Y is extremely small.

A method for preparing a metal composite plate by rolling includes the following steps: 1) rolling composite surfaces of a base plate and a cladding plate, respectively, to obtain the base plate corrugation and the cladding plate corrugation for mating with each other; 2) cleaning the composite surfaces of the base plate and the cladding plate to expose the metal matrixes of the base plate and the cladding plate; 3) laminating the base plate and the cladding plate sequentially so that the base plate corrugation on the base plate and cladding plate corrugation on the cladding plate mate with each other, compacting, and performing welding sealing treatment to the base plate and the cladding plate to obtain a composite plate slab; and 4) rolling the composite plate slab after inspection by using a compositing machine to a desirable thickness, to obtain a metal composite plate.
