A falling film evaporator includes a flow distributor for uniformly distributing a two-phase refrigerant mixture across a tube bundle. The flow distributor includes a stack of at least three perforated plates each of which are separated by nearly full-width, full-length gaps or chambers. The flow distributor may also include a suction baffle and / or a distributor baffle. The distributor baffle extends downward to provide a hairpin turn past which refrigerant travels before exiting the evaporator. This directional change helps separate liquid from a primarily gaseous refrigerant stream. The suction baffle has various size openings to ensure that the flow rate of refrigerant through the hairpin turn is generally uniform and is maintained low enough to ensure liquid disentrainment over and along the length of the tube bundle within the evaporator.

A method is disclosed for two-stage stretch forming of a sheet metal blank workpiece between a preform tool with a concave cavity and an opposing finish-form punch tool. Both tools are independently heated to different forming temperatures with the preform tool being hotter. Gas pressure is first applied to one side of the workpiece in the first forming stage to balloon it into the cavity of the preform tool. Gas pressure is then applied to the other side of the preformed workpiece to stretch it against the finish-form surface. The hotter preform tool enables faster forming and gas venting in the first stage. The cooler finish-form tool enables the final shaping of the part and its undistorted removal from the punch surface.
