Abstract
A method of fabricating a folded evaporator tube includes providing a tube with a plurality of webs extending between interior surfaces of the tube. The webs are oriented at an angle between forty-five degrees (45°) and sixty degrees (60°) of angle relative to a bottom wall of the tube. A cutting-device that includes a knife and a guide that cooperate to cut the tube to a desired length is also provided. The knife has a point that is forced in a direction parallel to a wall of the tube. The guide defines an opening that conforms to the tube to maintain the shape of the tube during cutting by the knife. The knife further defines a bottom and top edges that extend away from the point and cooperates with the opening to shear the bottom and top walls of the tube along with internal webs inside the tube.
