ABSTRACT:
An automotive air conditioning system evaporator of laminated construction has tube plates, which, in brazed pairs, make up the individual flow tubes, that have an additional feature to assure regular, evenly spaced stacking of the tube plates prior to final assembly. Integrally stamped cups on one end of the plates nest to hold the cup end of the plates apart a defined distance when the plates are stacked. Spacer flanges on the opposite end of the plates interfit to keep the completed tubes spaced apart sufficiently to accommodate cooling fins in the final evaporator, but, without more, do nothing to keep the flange end of the plates evenly stacked. Special projections added to the spacer flanges contact edges of the spacer flanges of consecutive plates in the stack to keep the plates evenly spaced at both ends.
