A method and apparatus for manufacturing a heat exchanger. A plurality of parallel pipes are advanced from a magazine to an axially slotted open ended shell blank which is radially compressed against the pipes. The contacting surfaces of the pipe openings are then welded together, after which the ends of the package of pipes are immersed in a casting mass, which, after solidifying, is severed along a line therethrough so as to open the pipes at both ends. A wall enclosing each open end is then connected to each end of the pipe package. |
