Abstract

A double pipe type heat exchanger includes an inner pipe (10) having a first flow path (12) defined therein and an outer pipe (20) arranged around the inner pipe (10) to define a second flow path (30) between the inner pipe (10) and the outer pipe (20). The inner pipe (10) includes a spiral groove (14) formed on an outer circumferential surface of the inner pipe (10) to extend along a longitudinal direction of the inner pipe (10). The outer pipe (20) includes a reduced diameter portion (40) protruding inwardly so that the inner surface of the outer pipe (20) is intermittently contacted with the outer circumferential surface of the inner pipe (10).
