Tab for an automotive heat exchanger

摘要

The tab comprises a generally planar web interconnecting adjacent plates. The web includes a first edge having a number of recesses disposed at predetermined locations along it and a second edge having a number of recesses disposed opposite the number of recesses along the first edge. The number of recesses define first and second bend zones which provide proper plate-to-plate contact when forming the plate tubes as well as proper fin height spacing between adjacent pairs of plate tubes.
