熱交換器。 In a double-tube heat exchanger, in which another heat exchanger tube with a smaller diameter is inserted inside the heat exchanger tube and heat exchange is performed through the inner heat exchanger tube wall, a single tube outside the inner heat exchanger tube or Indentations are made intermittently on the outer surface of the tube at regular intervals along multiple spiral curves, and at the same time, the indentations on the outside of the tube cause the inner surface of the tube to have a circular or elliptical cross-sectional shape at the bottom and at any height. Alternatively, a heat exchanger characterized by having a row of protrusions having an asymmetrical elliptic curve and whose cross-sectional area decreases in the height direction.
