SQUARE ENDFORM TUBE BUNDLE
Document Type and Number:
WIPO Patent Application WO2002025204
Kind Code:
A3
Abstract:
The heat exchanger of the present invention includes a plurality of tubes (16) each including a pair of square endforms (18) and a tubular body (20). The square endforms (18) are stacked to form a tube bundle (26). The plurality of tubes (16) carry exhaust gas which exchanges heat with coolant flowing in a shell (34) that encloses the of tubes (16). Each square endform (18) includes four flat faces (22a, 22b, 22c and 22d) each having a corresponding edge (24a, 24b, 24c and 24d) forming a square. The square endforms (18) of the tubes (16) are stacked to form a tube bundle (26) of a desired size and shape. Once the endforms (18) of the tubes (16) are positioned in the desired shape, a weld bead (30) is applied over the adjacent edges (24a, 24b, 24c and 24d) of the stacked square endforms (18), securing the tubes (16) together to form a tube bundle (26).
