PROBLEM TO BE SOLVED: To suppress drift current of a fluid passing through a core, in a heat exchanger 1 including a core 2 having at least a first passage 21 where a first fluid flows and a second passage 22 where a second fluid flows.SOLUTION: A first passage includes a plurality of channels connecting an inflow port opening at an inflow surface 31 of a core and an outflow port opening at an outflow surface 32, and between the channels, a flow passage resistance is different from each other. A heat exchanger is disposed on the inflow surface side relative to the core, and includes: a first type rectification member 51 for equalizing dynamic pressure distribution to the inflow surface of a first fluid flowing into the core; and a second type rectification member 52 for reducing passage flow rate difference resulting from the flow passage resistance difference between the channels. |
