Method of making counterflow fluid condensers

Abstract

Abstract A COUNTERFLOW FLUID CONDENSER WHICH INCLUDES A PAIR OF OPPOSITE CHAMBERED MANIFOLD HEADS AND A PLURALITY OF TELESCOPICALLY ASSOCIATED PIPE PAIRS CONNECTED BETWEEN SAID HEADS TO THE RESPECTIVE CHAMBERS THEREOF, THERE BEING DEFINED ONE INDEPENDENT PATH WITH APPROPRIATE INLET AND OUTLET FOR CONDENSATE AND ANOTHER INDEPENDENT PATH WITH APPROPRIATE INLET AND OUTLET FOR COOLANT, THE MANIFOLD HEADS EACH BEING FORMED AS ELONGATE U-SHAPED HOUSING DIVIDED INTO A PLURALITY OF CHAMBERS BY SPACED CROSSBAFFLES SEATED THEREIN AND SUPPORTED BY RESPECTIVE PARALLEL SPACED RIB PAIRS FORMED ALONG THE INNER SURFACE OF THE FLOOR AND SIDES OF SAID HOUSING, A PLURALITY OF BRIDGING PLATES SEATED ON RESPECTIVE ONES OF BRIDGING RIBS LIKEWISE FORMED ON THE INNER SURFACE OF THE SIDE WALLS OF SAID HOUSING, THE FLOOR OF SAID HOUSING BEING PROVIDED WITH FIRST PERFORATIONS OF SIZE AND CONFIGURATION TO RECEIVE THERETHROUGH THE OUTER ONE OF SAID PIPE PAIRS AND THE BRIDGING PLATES EACH BEING PROVIDED WITH A SECOND PERFORATION FOR RECEIVING THERETHROUGH THE INNER ONE OF SAID PIPE PAIRS, SAID BRIDGING BAFFLES ALSO HAVING MEANS FOR RECEIVING STUD FASTENERS AND SUITABLE WASHER AND COVER MEANS BEING SECURED TO THE BRIDGING PLATES UTILIZING SAID STUD FASTENERS, THE COOLANT PATH TRAVERSING SAID CHAMBERS AND THE CONDENSATE PATH BEING NON-COMMUNICATING WITH SAID CHAMBERS. THE NOVEL METHOD OF MAKING THE CONDENSER BEING CHARACTERIZED BY THE STEPS OF FORMING A MANIFOLD HEAD SUB-ASSEMBLY BY IMPRESSING A PLURALITY OF GROOVES IN ONE FACE OF A SHEET METAL BLANK AT PREDETERMINED LOCATIONS THEREON SIMULTANEOUSLY FORMING RIBS ON THE OPPOSITE FACE THEREOF, BENDING SAID GROOVED BLANK TO AN INWARDLY RIBBED, U-SHAPED CONFIGURATION TO DEFINE A FLOOR HAVING SECTIONS DEFINED BETWEEN THE RIB PAIRS AND OPPOSITE EQUAL SIDE WALLS WITH THE GROOVES ON THE EXTERIOR THEREOF, PERFORATING SAID FLOOR WITHIN EACH SECTION, ASSEMBLING CROSS-BAFFLES AND BRIDGING PLATES UTILIZING SAID RIBS AS SUPPORT THEREFOR SO AS TO DEFINE THE PLURALITY OF MANIFOLD CHAMBERS, ONE CHAMBER FOR EACH SECTION, ENGAGING RESPECTIVE ONES OF SAID PIPE PAIRS THROUGH RESPECTIVE ONES OF SAID PERFORATIONS, INSTALLING THE STUD FASTENERS ON THE BRIDGING PLATES AND THEREAFTER COPPER-BRAZING THE THUS CONSTRUCTED SUBASSEMBLY IN AN OVEN AND THEREAFTER APPLYING AND SECURING SUITABLE WASHERS AND COVERS TO OPPOSITE MANIFOLD HEADS THEREAFTER TO COMPLETE THE COUNTERFLOW CONDENSER, THE COOLANT AND CONDENSATE INLETS AND OUTLETS BEING PROVIDED IN ONE OF SAID MANIFOLD HEADS.
