<P>PROBLEM TO BE SOLVED: To suggest a shell and tube type heat exchanger, which has an increased heat transfer area by high-density of tubes and elongation of pipe lines, has superior heat efficiency, is in no need of special holding means for the tubes, and has superior assembling workability and productivity. <P>SOLUTION: In the shell and tube type heat exchanger in which a plurality of tubes is accommodated in a shell 10 along the axial direction, fluid on one side for changing heat flows in the tubes 1, the other fluid flows in clearances between the shell 10 and the tubes 1, and two kinds of fluids exchange heat, the tubes 1 are formed in a spiral shape by spiral working, the plurality of tubes 1 is coaxially bundled while each tube 1 is separated and is arranged in the shell, characteristically. <P>COPYRIGHT: (C)2013,JPO&INPIT |
