A HEAT EXCHANGER FOR AN AIR CONDITIONER COMPRISES A PLURALITY OF HEAT-TRANSFER TUBES (1,1A-1E) ARRANGED IN PARALLEL TO EACH OTHER AT PREDETERMINED INTERVALS, AND HEAT-TRANSFER FINS (2A-2C) FORMED BY HELICALLY WINDING A PLURALITY OF FINE WIRES AROUND THE PLURALITY OF HEAT-TRANSFER TUBES (1, 1A-1E). PREFERABLY, THE HEAT-TRANSFER TUBES ARE DIVIDED INTO GROUPS OF TWO ADJACENT HEAT-TRANSFER TUBES (1A,1B), (1B, 1C), (1C, 1D), ..., AND AT LEAST ONE FINE WIRE FIN (2A-2C) IS WOUND HELICALLY AROUND THE TWO ADJACENT HEAT-TRANSFER TUBES (1A, 1B), OF EACH GROUP SO THAT THE FINE WIRE FIN DOES NOT CROSS OTHER PORTIONS OF THE FINE WIRE FIN (2A- 2C) AS VIEWED ALONG A DIRECTION PERPENDICULAR TO A PLANE INCLUDING THE AXES OF THE PLURALITY OF HEAT-TRANSFER TUBES. WHEN FABRICATING THE HEAT EXCHANGER, AT LEAST EITHER THE OUTER CIRCUMFERENCES OF THE HEAT-TRANSFER TUBES (11) OR THE OUTER CIRCUMFERENCES OF THE FINE WIRES ARE COATED WITH A METAL FILM (13) FORMED BY PLATING, AND THEN THE HEAT-TRANSFER TUBES AND THE FINE WIRES ARE INTERLACED TO FORM A HEAT EXCHANGING STRUCTURE. THEN, THE HEAT EXCHANGING STRUCTURE IS HEATED TO THE MELTING POINT OF THE METAL FILM (13) SO THAT THE METAL FILM IS MELTED AND THE HEAT-TRANSFER TUBES AND THE FINE WIRES ARE BONDED TOGETHER BY THE MOLTEN METAL FILM.(FIG 4) |
