<p>The present invention relates to an SRC tube brazing apparatus. The SRC tube brazing apparatus, in which a clad tube and a cooling fin is put into an electric heating furnace to braze the cooling fin on an outer circumference surface of the clad tube to thereby manufacture a single row condensing tube, includes: a jig frame; a first skid set supported by the jig frame to support a lower surface of at least one or more clad tubes, the first skid set having a seat groove which has a shape corresponding to that of a lower end of the clad tube to prevent the tube from being warped or twisted by thermal deformation at a high temperature within the electric heating furnace after the tube is seated on the plurality of clad tubes; heat fillers for guiding brazed positions of a plurality of cooling fins disposed to face both side surfaces of the plurality of clad tubes seated on the first skid set, the heat fillers being disposed between the cooling fins so that the cooling fins adjacent to each other do not contact each other; and a pressing unit disposed on each of both sides of the jig frame, the pressing unit previously contacting and pressing the outermost heat filler of the heat fillers surrounding the clad tubes and the cooling fin which are put into the electric heating furnace to closely attach the clad tube and the cooling fin to each other at a uniform pressure.</p> |
