A heat exchanger for several applications such as a vehicle is described herein. The heat exchanger includes an inlet header tank configured to receive a fluid, an outlet header tank configured to output the fluid, and an intermediate tank between the inlet header tank and the outlet header tank. A first heat exchanger is between the inlet header tank and the intermediate tank, and a second heat exchanger is between the intermediate tank and the outlet header tank. The intermediate tank has an interior region having a plurality of protuberances disposed therein. The protuberances are configured to facilitate mixing of the fluid within the intermediate tank. The mixing of the fluid with the protuberances provides a more uniform heat distribution within the intermediate tank before entering the second heat exchanger.

An automotive heat exchanger () has a heat exchanger core () including a header part () with a plurality of heat transfer tubes () and a head tank () with an opening receives end portions of the heat transfer tubes (). A plastic header plate () is secured with the header tank () and header part (). The header plate () includes a plurality of apertures () extending through the plate () that enable fluid passage. Each aperture () includes a cutout portion () that receives an end of a heat transfer tube (). The cutout portion () has a complimentary shape to mate with the end of the heat transfer tube (). A seal (), in the cutout portion (), seals the end of the heat transfer tube () with the header plate ().
