Abstract
A heat exchange tube for use in a heat exchanger including a first nose and a second nose aligned on an axis along a width of the heat exchange tube; an end port immediately adjacent to the first nose; wherein the end port has a non-circular, polygonal shape.
Claims17
A heat exchange tube for use in a heat exchanger, the heat exchange tube comprising:
- a first nose and a second nose aligned on a Y axis along a width of the heat exchange tube;
- an end port immediately adjacent to the first nose;
- a first interior port positioned between the first nose and the second nose;
- a second interior port positioned between the first nose and the second nose;
- the first interior port having a planar wall extending from one side of the first interior port to a second side of the first interior port, a distance from the planar wall of the first interior port to an outer surface of the heat exchange tube defining a wall having a first thickness, B2, along a Z axis perpendicular to the Y axis;
- the second interior port having a planar wall extending from one side of the second interior port to a second side of the second interior port, a distance from the planar wall of the second interior port to the outer surface of the heat exchange tube defining a wall having a second thickness, B1, along the Z axis;
- wherein the first thickness, B2, is greater than the second thickness, B1;
- a further first interior port having a planar wall extending from one side of the further first interior port to a second side of the further first interior port, a distance from the planar wall of the further first interior port to the outer surface of the heat exchange tube defining a wall having the first thickness, B2, along the Z axis.
