Abstract:
1. A heat exchanger comprising: a core that includes a plurality of tubes, which are configured to conduct fluid; and two header tanks that are placed at two opposed longitudinal ends, respectively, of the plurality of tubes and are communicated with the plurality of tubes, wherein: each of the two header tanks includes: an inner surface of the core plate includes: the outer peripheral sealing surface includes: the corresponding plane of the at least one primary section is generally parallel to the corresponding plane of the at least two tube connecting surfaces and is placed on a side of the corresponding plane of the at least two tube connecting surfaces where an outside of the header tank is located; the corresponding plane of the at least one boundary portion sealing surface is displaced from the corresponding plane of the at least one primary section in a direction perpendicular to the corresponding plane of the at least one primary section within a range that does not exceed the corresponding plane of the at least two tube connecting surfaces on a side where an inside of the header tank is located; and the corresponding plane of the at least one secondary section is the same as the corresponding plane of the at least one boundary portion sealing surface.
