BLAZING APPARATUS FOR ALUMINUM CLAD OBLONG TUBE FOR AIR COOLING SYSTEM CONDENSING PLANT

摘要

The present disclosure discloses a brazing apparatus for aluminum (AL) clad oblong tube for air cooling system condensing plant by inputting a clad. tube and a cooling fin to an electric heating furnace to braze the cooling fin to a periphery of the clad tube, the apparatus comprising: a jig frame; a first skid set supporting the j ig, supporting a bottom surface of at least one clad tube and having an accommodation groove having a shape corresponding to a bottom shape of the clad tube to prevent the steam condensing tube from being bent and twisted by thermal deformation under a high temperature inside the electric heating furnace after the plurality of clad tubes are accommodated in arrangement positions; heat fillers guiding blazing positions of a plurality of cooling fins each to face both lateral surfaces of the plurality of clad tubes accommodated in the first skid set, and interposed between respective cooling fins to prevent adjacent cooling fins from being contacted to each other; and a pressure unit mounted at both sides of the jig frame to apply a line-contact pressure from both sides on an outmost heat filler among heat fillers wrapping the clad tube inputted into the electric heat furnace and the cooling fin and to tightly contact the clad tube to the cooling fin.
