Patent abstract
A heat exchanger includes a fin arranged in a first passage and a tubular tank portion formed so as to penetrate plate members stacked in a stacking direction. An inflow port is formed in a peripheral wall of the tank portion to allow a refrigerant to flow into the first passage. When the fin is arranged in a fin installation portion in the first passage, a passage reduction portion is formed at the inflow port and is narrower than a width of the fin installation portion in the stacking direction.
