Abstract
A laminated-type evaporator for an automotive air conditioning refrigerant circuit includes a plurality of tube units having a pair of tray-shaped plates. Each of the tray-shaped plates includes a depression defined therein, a flange extending about the periphery thereof, and a wall disposed at an intermediate location therein and extending a portion of the length of each plate to thereby define a rear side and a front side to each plate. The wall includes a flat portion formed at an upper end thereof. A slit is formed at the flat, upper end portion of the wall by shearing. The slit extends along substantially the entire length of the wall along the wall's longitudinal axis.
