Abstract
An improved automotive condenser and method for its production is disclosed, having particular application in cooling utilities wherein resistance to high internal fluid pressures is required. The condenser comprises elongated hollow energy exchange structures extending between header tanks, the hollow structures being formed from opposing elongated plates, undulating in cross-section to form a plurality of longitudinally extending opposing crests and valleys, wherein the opposing valleys are crossed, at a maximum distance between points of crossing valleys of no greater than about 0.2 inches, and said crossing valleys are joined at substantially all crossing points defining longitudinally extending hollow passages between the connected valleys.

An improved automotive condenser, comprising elongated, generally rectangular, hollow energy exchange structures extending between header tanks, said hollow structures comprising first and second opposing elongated plates joined along elongated longitudinal edges to define a tube having a generally rectangular cross-section with generally rounded edges and a passage extending in a longitudinal direction, said opposing plates undulating in cross-section to define generally parallel crests and valleys obliquely angled to the longitudinal direction and set away from the rounded longitudinal edges of the tube, valleys of the first opposing plate being angularly disposed to cross opposing valleys of said second plate, at a maximum distance between points of crossing valleys of no greater than about 0.2 inches and said crossing valleys being joined at substantially all crossing points, said longitudinal edges of said elongated plates forming longitudinally extending passages at the edges comprising a generally rounded exterior edge surface.
An improved automotive condenser, comprising elongated, generally rectangular, hollow energy exchange structures extending between header tanks, said hollow structures comprising first and second opposing elongated plates, having an average thickness of from about 0.012 to about 0.030 inches, joined along elongated longitudinal edges to define a tube having a generally rectangular cross-section with generally rounded edges and a passage extending in a longitudinal direction, said opposing elongated plates undulating in cross-section to define generally parallel crests and valleys obliquely angularly disposed to the longitudinal direction and set away from the rounded longitudinal edges of the tube, with valleys of the first opposing plate being angularly disposed to cross valleys of the second opposing plate, at a maximum distance between points of crossing valleys of no greater than about 0.2 inches and being joined at substantially all crossings, said longitudinal edges of said elongated plates forming longitudinally extending passages at the edges comprising a generally rounded exterior edge surface.
