Abstract
The disclosure relates to a heat exchanger-type laminated evaporator, in which a plurality of liquid passage pipe units are arranged in side-by-side relation to form flat liquid passage pipes which communicate at their ends, with enlarged portions forming reservoirs, each of which communicates through a perforation in the wall thereof with an adjacent liquid reservoir, thereby forming an inlet manifold and an outlet manifold and intermediate manifolds. Adjacent manifolds are separated from each other by a common imperforate wall and the imperforate walls at one end are staggered relative to those at the other end, so that refrigerant introduced into the inlet manifold flows through a set of the flat liquid passage in one direction and then through an adjacent set of flat liquid passage pipes in the other direction, and so on, until the outlet manifold is reached. The liquid passage pipe units are made of mirror-image stampings fastened rim-to-rim to form the flat liquid passage pipes and the reservoirs at the ends thereof.
