Abstract: In a heat exchanger, when louvers are viewed from an airflow direction, a louver tip end width becomes shorter with increase of a louver height. A fin width of the fin is 14 mm or shorter. Airflow-end louver lengths of an upstream-end first louver, a downstream-end first louver, an upstream-end second louver, and a downstream-end second louver are “⅝×LP” or longer, where LP is a louver pitch.

Abstract: A heat exchanger has a core plate connected to a tank member by clamping claws. The tank member has a waved outer surface including outer ridge portions and outer valley portions which are disposed alternately. The tank member also has a waved inner surface including inner ridge portions and inner valley portions which are disposed alternately. The outer valley portions are capable of receiving the claws. The inner ridge portion is positioned inside the outer valley portion in a width direction. The inner ridge portion is positioned between the adjacent tubes and/or between extensions of the tubes in a height direction. An inner width of the tank member regulated by the inner ridge portions is narrower than a width of the tube.

Abstract: The heat exchanger has tubes and a header tank that is located at an end of the tubes in a longitudinal direction and communicates with the tubes. The header tank has a core plate that connects to the tubes and a tank body that is fixed to the core plate. The core plate has a tube connection surface, a sealing surface, and an inclined surface that connects the tube connection surface and the sealing surface with each other. A distance between the tube connection surface and an end surface of the tubes in the longitudinal direction is different from a distance between the sealing surface and the end surface in the longitudinal direction by disposing the inclined surface to incline with respect to the longitudinal direction. The tubes connect to the tube connection surface and the inclined surface in a condition of being inserted to the tube connection surface and the inclined surface.
