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.

Abstract translation: 热交换器具有管和集管箱，其在纵向方向上位于管的端部并且与管连通。 集水箱具有连接到管的芯板和固定到芯板的罐体。 芯板具有管连接表面，密封表面和将管连接表面和密封表面彼此连接的倾斜表面。 通过使倾斜面相对于长度方向倾斜，管连接面与长边方向的端面之间的距离与密封面与端面的长度方向的距离不同。 在插入到管连接表面和倾斜表面的状态下，管连接到管连接表面和倾斜表面。
