Abstract
A heat exchanger includes a heat exchanger core, a pressure housing, and a flex beam. The pressure housing at least partially defines a core chamber. The flex beam extends between and connects the heat exchanger core and the pressure housing such that the heat exchanger core is suspended away from the pressure housing within the core chamber by the flex beam. The flex beam includes a core end connected to the heat exchanger core and a housing end spaced along the flex beam from the core end and connected to the pressure housing.
Claims20
A heat exchanger comprising:
- a heat exchanger core;
- a pressure housing at least partially defining a core chamber;
- and
- a flex beam extending between and connecting the heat exchanger core and the pressure housing such that the heat exchanger core is suspended away from the pressure housing within the core chamber by the flex beam, the flex beam including a core end connected to the heat exchanger core and a housing end spaced along the flex beam from the core end and connected to the pressure housing;
- wherein a radially inner edge of the flex beam is convex at a first point disposed between the housing end and the core end and a radially outer edge of the flex beam is concave at the first point;
- and
- wherein the radially inner edge of the flex beam is concave at a second point disposed between the housing end and the core end and the radially outer edge of the flex beam is convex at the second point.
4 more elements
A heat exchanger comprising:
- a heat exchanger core;
- a pressure housing at least partially defining a core chamber, the pressure housing extending about an axis;
- and
- a first flex beam extending between and connecting the heat exchanger core and the pressure housing, the first flex beam comprising:
- a core arm extending between a core interface, at which a core end of the flex beam interfaces with the heat exchanger core, and a flex beam body of the first flex beam;
- and
- a housing arm extending between a housing interface, at which a housing end of the flex beam interfaces with the pressure housing, and the flex beam body, the housing arm including a first bend disposed between the flex beam body and the housing end such that the flex beam extends towards the pressure housing between the first bend and the housing end and a second bend disposed between the first bend and the flex beam body, such that the flex beam extends radially inward from the second bend to the first bend and the flex beam extends radially outward from the first bend to the housing end;
- wherein the flex beam body is elongate along the axis;
- wherein the length of the flex beam body is greater than the length of the housing arm;
- wherein the core arm extends radially and axially between the flex beam body and the heat exchanger core;
- wherein the housing arm extends radially and axially between the flex beam body and the pressure housing;
- and
- wherein the first bend and second bend are disposed in a spacing gap formed between the heat exchanger core and the pressure housing;
- wherein the first flex beam supports the heat exchanger core within the core chamber such that a spacing gap is formed radially between the heat exchanger core and the pressure housing.
