ABSTRACT:
Apparatus for cleaning and drying components, such as electronic or electrical components, by contact with a flammable liquid organic solvent, such as alcohol for example, including a reservoir (24) for a highly fluorinated compound, a heating device (22) for heating the reservoir and evaporating the highly fluorinated compound therefrom, a cleaning chamber (12) containing the liquid organic solvent (21) into which the components to be cleaned are emersed for cleaning, a fluid conduit (25) for conducting highly fluorinated compound vapor from the reservoir (24) to the cleaning chamber (12) to cover the organic liquid (21) in the cleaning chamber and directly heating the organic liquid, cooling coils (13) on which the vapor above the organic liquid condenses in the tank (12). Heavy, largely immiscible condensate sinks to the bottom of the tank (12) and is pumped by a pump (20) through a filter (19) to a gravity separator (14). In the separator (14) the fluorinated compound returns by gravity to the reservoir, or boiling chamber (24) and the organic liquid returns to the tank (12) through conduits (18 and 16, respectively).
