A heat exchanger which is particularly useful as evaporator has a first plurality (C) of stacked plate pairs (14) with cooling fins (8) therebetween located adjacent to a second plurality (D) of stacked plate pairs. Each plurality of plate pairs has enlarged plate end portions (22, 26) which together define flow manifolds (32, 34). The first plurality (C) of plate pairs has a first inlet manifold and a first outlet manifold. The second plurality (D) of plate pairs has a second inlet manifold and second outlet manifold. The first outlet manifold is joined to communicate with the second outlet manifold. The second inlet manifold is joined to communicate with the first inlet manifold, but a barrier (12, 64) is located between the first and second inlet manifolds. The barrier has an orifice (17) to permit a portion only of the flow in the first inlet manifold to pass into the second inlet manifold to produce a more uniform flow distribution inside the heat exchanger. |
