Abstract
A heat exchanger includes a first additively manufactured layer including axial fins extending in a first direction and transverse fins extending in a second direction transverse to the first direction, the first layer defining a flow path in the first direction. The heat exchanger also includes a second additively manufactured layer including axial fins extending in the second and transverse fins extending in the first direction, the second layer defining a second flow path in the second direction.
Claims10
A layer of a heat exchanger comprising:
- a top additively manufactured layer including a flat base layer and axial fins extending in a first direction on the base layer and transverse fins extending in a second direction on the base layer transverse to the first direction, the axial fins and the transverse fins extending outwardly from a single side of the base layer of the top additively manufactured layer;
- and
- a bottom additively manufactured layer including axial fins extending in the first direction and transverse fins extending in the second direction;
- wherein upper surfaces of the transverse fins of the top additively manufactured layer contact a peak portion of the axial fins of the bottom additively manufactured layer.

A method of forming a layer of a heat exchanger comprising:
- additively manufacturing a top layer including a flat base layer and axial fins extending in a first direction on the base layer and transverse fins extending in a second direction on the base layer transverse to the first direction, wherein the axial fins and the transverse fins extending outwardly from a single side of the base layer of the additively manufactured top layer;
- additively manufacturing a bottom layer including axial fins extending in the first direction and transverse fins extending in the second direction;
- and
- placing the top additively manufactured layer on the bottom additively manufactured layer such that upper surfaces of the transverse fins of the top additively manufactured layer contact peaks of the axial fins of the bottom additively manufactured layer.
