Zusammenfassung:	A heat exchanger having a core of a plurality of cooling tubes with a tank at each end of the core tubes. The tanks are formed with a plurality of cooling tube receiving apertures along a side portion of the tanks. These apertures receive the ends of the cooling tubes directly into the tanks and are attached to the tubes by brazing. Since the cooling tubes are received in apertures formed in the tanks themselves, the need for a separate head sheet at the end of the core is eliminated thereby eliminating the need for sealing of a head sheet to a separate tank. The tanks are preferably formed in a hydroforming operation to shape the tanks from a tubular blank.
