Abstract
A heat exchanger includes two parallel tank units forming a fluid space therein, and supporting a core therebetween. The core includes parallel tube passes connected between the tank units, and air centers connected between the tube passes for conductive heat exchange with air flowing therethrough. The header includes tube slots therein for receiving the ends of the tube passes in fluid communication with the fluid space. The tank units are comprised of a separate header and tank. The tank is formed of a U-shaped extrusion with grooves formed in the opposing arms thereof. The header is arcuately shaped and includes side edges parallel to one another to be received within the grooves for connecting the header to the tank.
