Abstract
Abstract An apparatus especially suitable for distilling water is disclosed. This apparatus, as disclosed, includes first and second separate and distinct groups of adjacent, confronting plate members, each of which alternatively defines a series of boiling and condensing chambers and a compressor. The apparatus also includes a device for fluid connecting the various boiling and condensing chambers and compressor to one another so that feed water can first be converted to steam in the boiling chambers, then compressed in the compressor, and finally condensed into pure water in the condensing chambers. The two groups of plate members are connected to and supported by a combination manifold/support assembly which serves both as part of the fluid connecting device and as a device for supporting the confronting plate members.
