Claims

[Scope of utility model registration request]

(1) A bulge with a chevron-shaped cross section that bulges outward so as to divide the circumference of the circular pipe into 4 to 6 parts, with a height of 3 to 5 times the height of the bulge in the length direction of the circular pipe. It has an inner tube formed by bulge processing in multiple rows at different pitches and the dividing position of the bulging portion is shifted by one pitch, and an inner diameter that allows the inner tube to be inserted, and an inlet/outlet for the liquid to be cooled near both ends. 1. A heat exchanger comprising: an outer tube provided therein; the inner tube is inserted into the outer tube, and both tubes are joined at their ends.

(2) The heat exchanger according to claim 1, which is a registered utility model, in which a bulge is formed between the outlet and inlet of the liquid to be cooled in the outer tube.
