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.

A heat exchanger type laminated evaporator, which comprises a plurality of sets of complementary liquid passage pipe units arranged side-by-side to form flat liquid passage pipes which are formed by complementary shallow, flat portions of said units and reservoirs at each end thereof formed by complementary bulges at both ends of said flat portions, which reservoirs communicate with each other through penetrating holes in common, contiguous walls forming manifolds for the sets of said liquid passage pipes, wherein adjacent said manifolds are separated by a contiguous wall having no penetrating hole therein, and wherein the imperforate, contiguous wall between adjacent manifolds at one end of said liquid passage pipes is staggered in relation to the imperforate, contiguous wall between adjacent manifolds at the other end thereof, whereby liquid is constrained to flow in one direction from an inlet manifold through a set of said liquid passage pipes and then in the opposite direction through an adjacent set of liquid passage pipes and so on, until the outlet manifold is reached; and inlet means for introducing liquid into said inlet manifold; and outlet means for conducting liquid out of said outlet manifold.
