DOUBLE PIPE STRUCTURE FOR HEAT EXCHANGER AND ITS PROCESS OF MANUFACTURE

Japanese Patent JP2017198411

A

PROBLEM TO BE SOLVED: To provide a double pipe structure for a heat exchanger capable of improving a heat exchanging efficiency between fluids passing through each of an outer pipe and an inner pipe and provide its process of manufacture and additionally to provide a double pipe structure for a heat exchanger capable of facilitating manufacturing of the double pipe structure and its process of manufacture.SOLUTION: This invention relates to a double pipe structure 1 for a heat exchanger configured in such a way that a heat exchange can be carried out between outer fluid passing through an outer pipe 2 and inside fluid passing through an inner pipe 3. In such a double pipe structure 1 as above, a division plate 4 is arranged along an extending direction inside the inner pipe 3. Such a division plate 4 as above is formed into a twisted shape where its fine elongated cross section is extended while being rotated by itself around a center of a central axis line 4a of the division plate 4 along its extending direction. Further, this invention relates to a process of manufacture of such a double pipe structure 1 as above.SELECTED DRAWING: Figure 7
