Abstract:
1. A flash evaporator assembly comprising: a vaporization chamber having a liquid inlet and a vapor outlet; an atomizer fluidly configured to ultrasonically vaporize a liquid introduced through the liquid inlet; a vapor nozzle fluidly cooperative with the vapor outlet such that the ultrasonically atomized vapor formed in the vaporization chamber is configured to pass through the vapor nozzle after having passed through the vapor outlet; and a collar positioned between the vaporization chamber and the vapor nozzle, the collar defining a non-filtered single opening with a substantially unobstructed vapor flowpath therethrough such that it increases a pressure in the vaporization chamber while leaving the conductance of the vapor through the vapor nozzle substantially unchanged such that the average rate of liquid accumulation on a substrate placed in fluid communication with the vapor nozzle is also substantially unchanged.
