Definitions

  • FIG. 1 is a cross-sectional view of a double-pipe heat exchanger according to an embodiment
  • FIG. 3 is a graph showing a relationship between heat transfer performance and a pitch W of a spiral part in a double-pipe heat exchanger according to an embodiment.
  • the second heat exchange tube 200 disposed inside the first heat exchange tube 100 may have a spiral part 210 .
  • the spiral part 210 may be formed at a surface of the second heat exchange tube 200 so as to be in the form of a screw, and the screw-shaped spiral part 210 may have multiple ridges 212 and grooves 214 .
  • the second heat exchange tube may include a cylindrical second fluid inlet port, which may be inserted into or provided at one side of the first heat exchange tube and through which a second fluid may pass; a cylindrical second fluid outlet port, which may be inserted into or provided at the other side of the first heat exchange tube and through which the second fluid may be discharged; and a screw-shaped spiral part continuously formed between the second fluid inlet port and the second fluid outlet port.
  • a temperature of a first fluid provided between the first and second heat exchange tubes may be different from that of a second fluid provided in the second heat exchange tube.
  • the second fluid provided in the second heat exchange tube may be one of a single-phase fluid or a two-phase fluid.
