1. A collecting tank for a heat exchanger, comprising:
at least one manifold for receiving a plurality of heat exchanger tubes of the heat exchanger;
the at least one manifold having a hollow space through which a fluid is flowable;
the at least one manifold including a bottom and a plurality of tank receptacles for receiving the plurality of heat exchanger tubes, the plurality of tank receptacles disposed in the bottom spaced apart from one another in a longitudinal direction and extending in a transverse direction, which extends transverse to the longitudinal direction;
wherein, in a height direction extending transverse to the longitudinal direction and transverse to the transverse direction, directed away from the hollow space, the bottom has at least one curvature directed to an outside;
wherein, in the transverse direction, the plurality of tank receptacles each extend over a receiving width;
wherein the at least one curvature has a curvature height extending between a first point of the at least one curvature, which protrudes maximally in the height direction, and a second point, which is nearest to the first point of the at least one curvature in the height direction, at which the at least one manifold has a maximum manifold width in the transverse direction;
wherein the at least one curvature protrudes from the bottom and extends completely across the bottom in the transverse direction; and
wherein a ratio between the curvature height and the receiving width is 0.05 to 1.5.
