Title:
HEAT EXCHANGER TUBE
Document Type and Number:
Japanese Patent JP2016161250
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchanger tube which can largely improve performance more than before when employed to a heat exchanger such as an EGR cooler.SOLUTION: In a heat exchanger tube, a flat tube main body 14 is employed which has such a shape that a plurality of pieces of circular pipes are made to approximate each other, aligned in a plane shape, and connected to each other with an approximating region between the circular pipes as a communication part 13, swirl flow formation protrusions 16 are formed at internal peripheral faces of circuit pipe parts 15 equivalent to the circular pipes of the flat tube main body 14 so as to progress along spiral trajectories which are coaxial with center axes O of the circular pipe parts 15, and swirl flows of an exhaust gas 10 can be individually formed at the respective circular pipe parts 15. A partitioning wall 17 is formed at least at a part of the communication part 13 at a latter half of the flat tube main body 14.SELECTED DRAWING: Figure 1
