Verfahren zum Herstellen eines gefalteten Kondensatorschlauch mit B-Form

摘要

A method of fabricating a condenser tube (20) having a pre-determined tube length (L) and multiple channels (22) including the steps of forming an aperture (26) in a flat strip (28) of metal; moving the flat strip (28) through a plurality of forming operations to fold into an enclosed tube containing channels (22), which channels (22) include the aperture (26) in their sides (24) and bottoms (25); and severing (72) the enclosed tube across the aperture to separate the enclosed tube into one condenser tube (20). The aperture (26) eliminates the need for the channel sides (24) to be severed, hence only the portion of the condenser tube (20) enclosing the channels (22) requires severing. Each pair of apertures (26) is spaced from the next pair of apertures (26) by the pre-determined tube length (L) so that each sever produces one condensing tube (20) of the pre-determined tube length (L) with the apertures (26) being divided into open notches (31). The invention also includes a heat exchanger utilizing the condenser tube (20) with channel sides (24) containing portions of the apertures (26).
