There is disclosed a solar energy collector assembly in which the working media is a liquid circulated through the several tubular collectors in series. The manifold device is of a design that is inexpensive to fabricate for detachably inserting tubular collectors into opposite sides of the liquid manifold. The assembly includes an inlet for liquid to enter an outer tube of the collector and flow in one direction to the end and thereat enter an inner tube and flow in an opposite direction to the other far end of the inner tube, finally transferring to the manifold outlet connected to the next tube or tubes in the series. The receptacles of the manifold for connecting the collector tubes are fabricated from metal stampings and/or castings and surrounded with molded insulation, such as foamed plastic, e.g. polystyrene, polyethylene, polyurethane or the like. |
