HEAT EXCHANGER

摘要

A heat exchanger has a core plate (24, 25) connected to a tank member (27, 28) by clamping claws (35, 235). The tank member has a waved outer surface (43) including outer ridge portions and outer valley portions which are disposed alternately. The tank member also has a waved inner surface (44) including inner ridge portions and inner valley portions which are disposed alternately. The outer valley portions (43b) are capable of receiving the claws. The inner ridge portion (44a) is positioned inside the outer valley portion in a width direction. The inner ridge portion (44a) is positioned between the adjacent tubes and/or between extensions of the tubes in a height direction. An inner width (Wir) of the tank member regulated by the inner ridge portions is narrower than a width of the tube (W22).
