A heat exchanger which is particularly useful as an evaporator has a first plurality of stacked plate pairs with cooling fins therebetween. A second plurality of stacked plate pairs is located adjacent to the first. Each plurality of plate pairs has enlarged plate end portions which together define flow manifolds. The first plate pairs have a first inlet manifold and a first outlet manifold. The second plate pairs have 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 is located between the first and second inlet manifolds. The barrier has an orifice 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.
