1. A heat exchanger configured for use with air in an x-direction based on the heat exchanger, comprising,
at least one first row of flat tubes and a second row of flat tubes arranged beforehand in the x-direction,
wherein the flat tubes are oriented in the z-direction based on the heat exchanger and are configured for use with a cooling fluid,
having an upper collecting tank and a lower collecting tank in the z-direction,
wherein a cooling fluid inlet and a cooling fluid outlet are connected in series to the lower collecting tank, wherein the cooling fluid inlet and the cooling fluid outlet are both disposed upon a protrusion that extends away from the flat tubes in the y-direction,
wherein the cooling fluid inlet and the cooling fluid outlet are configured to allow for fluid flow in a direction parallel to the fluid flow through the flat tubes,
wherein the flat tubes in each row are divided in the y-direction based on the heat exchanger into at least three flat tube groups,
wherein all flat tubes of a flat tube group are flowed through in the z-direction, and
wherein the cooling fluid inlet of the heat exchanger is communicatingly connected to a first flat tube group of the first row arranged in the y-direction in a middle region.
