摘要

A spiral heat exchanger is provided to disassemble only a desired angle to carry out maintenance and repair by fastening the angle of the heat exchange cell using a bolt and to maintain air tight seal whereby the flange and the gasket formed between the angles are fastened through protrusion and groove. A spiral heat exchanger comprises a pair of angles(203,202) which receive the top and bottom of a heat exchange cell and formed with a plurality of fastening holes; a flange including inlet and outlet holes connected to the flow channel of the heat exchange cells, a plurality of fastening protrusions and a plurality of fastening holes(250); gaskets including inlet and outlet holes and a plurality of fitting grooves and located on the top and bottom surfaces of the flange; and a cover including a central inlet/outlet hole, a plurality of fastening protrusions and a plurality of fastening holes and mounted on the top and the bottom of the heat exchange cell.
