| Title of Invention | AN IMPROVED FLAT PLATE SOLAR WATER HEATER. |
|---|---|
| Abstract | THE IMPROVED SOLAR WATER HEATER HAS A RECTANGULAR TROUGH AS A BASIC UNIT, FORMED FROM GLASS REINFORCED CEMENT. THE TROUGH HAS A NUMBER OF LONGITUDINAL SHALLOW AND WIDE CHANNELS. WITH RIDGES INBETWEEN. THE LONGITUDINAL CHANNELS JOIN AT LOWER AND UPPER END SIMILAR CHANNELS TO FORM MANIFOLDS ARE COVERED BY A METAL SHEET TO FORM CONDUITS FOR FLOW OF WATER. IN ORDER TO RESIST HYDROSTATIC PRESSURE ON METAL SHEET. A NUMBER OF HOLDING BOLTES PASS THROUGH THE METAL SHEET AND THROUGH. THE METAL SHEET WITH EXTERNAL SURFACE PAINTED BLACK IS FIRMLY HELD ON THE TROUGH ALONG THE EDGE WITH ELPOXY ADHESIVE. HOLDING CLAMPS AND BEAD OF EPOXY WITH FIBRE GLASS. THIS MAKES A WATERTIGHT CONSTRUCTION. THE TROUGH IS ADEQUATELY STRENGTHENED WITH WEBS ON THE BACK. THE TROUGH IS COVERED WITH A SHEET OF GLASS WITH SEALING ON EDGE. FABRICTION COST OF THIS SOLAR WATER HEATER IS MUCH LESS THAN THE CONVENTIONAL COLLECTOR WHICH USES COPPER PIPES AND ALUMINIUM TROUGH. HOWEVER, EFFICIENCY OF THIS COLLECTOR REMAINS EQUALLY GOOD AS THE HEAT TRANSFER IS DIRECT FROM METAL SHEET TO WATER INSTEAD OF THROUGH FINS ON PIPES IN THE CONVENTIONALS COLLECTOR. THIS IMPROVED LOW COST EFFICIENT UNIT WOULD WIDEN THE FIELD OF SOLAR WATER HEATING. |
