Abstract (en)

[origin: EP1867944A2] [Problem] To provide a heat exchanger in which the medium flow structure in a tube body is logically configured. [Solving Means] A heat exchanger comprising a tube body 200 comprising a first flow passage 211 and a second flow passage 221, an inlet part 310 and outlet part 320 for a medium that flows through the first flow passage, and an inlet part 330 and outlet part 340 for a medium that flows through the second flow passage in which heat exchange is effected between the medium flowing through the first flow passage and the medium flowing through the second flow passage by means of heat transmitted to the tube body, the tube body being formed by stacking of a plurality of flat first tubes 210 in which the first flow passage is provided and a plurality of flat second tubes 220 in which the second flow passage is provided, the plurality of first tubes and the plurality of second tubes being alternately stacked with uniformity along a longitudinal direction and a flatness direction thereof, and end parts 210a of the plurality of first tubes and end parts 220b of the plurality of second tubes being connected at the end parts of the tube body to each of a predetermined inlet part and outlet part with displacement therebetween in the flatness direction.
