Abstract
A heat exchanger tube assembly includes a tube. The tube includes a first end, a second end disposed opposite from the first end, an outer surface, and an inner surface defining an interior space. A plurality of channels are formed within the interior space. A first sleeve is fixed to the outer surface of the tube near the first end and a second sleeve fixed to the outer surface of the tube near the second end.
Claims10
A heat exchanger assembly comprising:
- a plurality of adjacent tubes, each tube of the plurality of adjacent tubes comprising:
- a first end;
- a second end disposed opposite from the first end;
- an outer surface;
- an inner surface defining an interior space;
- and
- a plurality of channels formed within the interior space;
- a first sleeve fixed to the outer surface of a first tube near the first end of the first tube, the first tube belonging to the plurality of adjacent tubes;
- a second sleeve fixed to the outer surface of the first tube near the second end of the first tube;
- a second tube belonging to the plurality of adjacent tubes;
- a third tube belonging to the plurality of adjacent tubes;
- a first manifold body that bounds a first cavity, wherein the first manifold body has a first side and a second side;
- a plurality of first slots defined by the first manifold body configured to receive a first portion of the first tube, a first portion of the second tube, and a first portion of the third tube, wherein the first portion of the first tube includes the first end of the first tube;
- a second manifold body that bounds a second cavity;
- a plurality of second slots defined by the second manifold body configured to receive a second portion of the first tube, a second portion of the second tube, and a second portion of the third tube, wherein the second portion of the first tube includes the second end of the first tube;
- a first baffle disposed in the second manifold body between the first tube and the second tube, the first baffle being configured to allow fluid flow from the first tube to the second tube;
- and
- a first wall disposed in the second manifold body between the second tube and the third tube, the first wall being configured to prevent fluid flow from the second tube to the third tube;
- wherein the first end of the first tube terminates within one of the plurality of first slots between the first side and the second side;
- wherein the first sleeve is adjacent to the first manifold body and entirely outside of the first cavity;
- and
- wherein a thickness of the second sleeve is less than a thickness of the first sleeve.
