Title:
DOUBLE PIPE FOR HEAT EXCHANGE
Document Type and Number:
WIPO Patent Application WO/2017/164456
Kind Code:
A1
Abstract:
The present invention relates to a double pipe, for heat exchange, in which: a spiral pipe is axially inserted into an outer pipe so as to increase the residence time of the fluid, which flows inside the outer pipe, through the spiral shape, thereby improving the heat exchange efficiency with the fluid, which flows inside the spiral pipe; grooves are formed along a furrow part of the spiral pipe so as to improve the flow directionality of the fluid; a space between the inner pipe and a joint part at an end of the outer pipe is expanded so as to reduce flow noise during the inflow and outflow of the fluid according to a pressure drop thereof; and resistance members protrude on the furrow part such that the residence time of second fluid increases, thereby enabling the heat exchange efficiency to further increase.
