A plate heat-exchanger (12) has an assembly of plates (16) defining and separating alternate passages (14, 16) for the flow of a refrigerant and a heat-exchange fluid. Aligned holes (15) in the plates (16) provide inlets and outlets for the refrigerant and heat-exchange fluid to the respective passages (14, 16). A refrigerant distribution tube (26, 37) is located in the refrigerant inlet defined by holes (15). The tube (26, 37) has outlet apertures (27, 38) which direct refrigerant into the refrigerant passage (14). Blanking members (29, 39) blank off part of the opening into each refrigerant passage (14) to confine the refrigerant flow from the apertures (27, 38) to a predetermined path towards the plate centreline to ensure even refrigerant distribution. |
