Abstract
A heat exchanger may include a block for separately conducting first and second fluids, and a box. The block may have flat tubes through which the first fluid is flowable and each of which may have a narrow tube side and a wide tube side. The box may have a base, the flat tubes being guided into the base via corresponding through-openings in the base. Each through-opening may have at least one raised edge, with at least one narrow edge side and at least one wide edge side, surrounding the corresponding flat tube. The wide edge side may be higher than the narrow edge side. The two may transition into one another via an inclination with a recess that may have a height lower than that of the narrow edge side. A contact surface edge may have a height lower at the recess than at the narrow edge side.
