ABSTRACT:
A heat transfer cell for employment in heating, ventilation and air conditioning applications, and an apparatus for producing metallic plates which can be employed in the construction of the heat transfer cell. The cell comprises a plurality of heat conductive plates stacked on each other and having upstanding fins extending substantially the length of each plate. A leading edge portion of each fin is folded laterally to thereby create a turbulent effect to air traveling linearly between adjacent fins and plates. The apparatus of the present invention comprises an endless chain having a plurality of generally equally spaced apart work supporting anvil links and a path deflecting, chain deflecting, idler roller operatively arranged to deflect the endless chain arcuately away from a preceding plane to thereby reduce the space between adjacent anvil links and simultaneously capture between the adjacent links a length of metallic material of a web traveling thereacross to thereby form a fin from the length of captured metallic material.
