ABSTRACT:
A buoyant elongated trough-like structure closed throughout an upper portion thereof by means of a transparent panel for passing radiant energy from the sun therethrough is provided and a portion of the interior of the trough below the transparent panel defines an open top compartment for receiving water to be evaporated and subsequently condensed. Lower and upper portions of one wall of the trough include inlet and outlet openings extending along the trough and a hollow U-shaped manifold extends longitudinally of the slotted side wall of the trough and opens toward the latter including a lower hollow leg opening into the interior of the trough through the lower slot and a hollow upper leg opening into the trough through the upper slot. The ends of the legs of the manifold remote from the trough are joined by means of an integral hollow bight portion. Further, a tapered baffle extends along the inner surface of the slotted side wall of the trough intermediate the upper and lower slots and projects inwardly of the slotted trough side wall. The interior of the trough disposed below the transparent panel, the upper and lower slots and the hollow U-shaped manifold define a closed loop passageway through which convection air may pass outwardly through the outlet slot and into the upper leg of the U-shaped manifold, downwardly through the hollow bight portion of the manifold, inwardly toward and through the inlet slot of the trough side wall via the lower leg of the U-shaped slot and about the tapered baffle before again passing outwardly through the outlet slot and into the U-shaped manifold. The open top of the water compartment within the trough below the transparent panel is communicated with the aforementioned convection passage for the ready commingling of water vapor escaping from the surface of the water heated within the compartment with the air circulating through the convection passage, the walls of the trough-like buoyant structure being insulative and the U-shaped manifold being disposed exteriorly of the buoyant trough structure below the normal water level thereof and also constructed of a material having good heat transferring properties as well as being provided with a lower sump portion for the collection of condensed water therein.
