The invention relates to a collector plate (11) for a heat exchanger (1), the collector plate (11) comprising: a peripheral groove (21) having a bottom (22), at least one upper step (25) protruding with respect to the bottom (22) of the said groove (21) over a predefined height (H1), and at at least one longitudinal end of the collector plate (11), an intermediate portion (27) between the upper step (25) and the said groove (21), According to the invention, at the said at least one longitudinal end of the collector plate (11), the said groove (21) has an inner wall (23), at least one section of which connects the intermediate portion (27) to the bottom (22) of the said groove (21) and extends over a height (H2) which is not zero and is less than the height (H1) of the upper step (25). The invention also relates to a corresponding header box (3) and a corresponding heat exchanger (1).

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.

A connecting pipe assembly and a heat exchanger is disclosed. The connecting pipe assembly includes: a pipe; and a first flange extending towards a radial outside from an outer peripheral surface of the pipe. The pipe includes a first insertion pipe section located on one side of the first flange in an axial direction of the pipe. Thereby the quality of the heat exchanger is improved.
