Abstract
A heat exchanger includes a plurality of flow passages in thermal contact with a cooling flow. The plurality of flow passages include a first end and a second end. An inlet manifold is at the first end of the plurality of flow passages. The inlet manifold includes a plurality of independent splitter passages that communicate airflow to the first end of the plurality of flow passages. An exhaust manifold is at the second end of the plurality of flow passages. A method is also disclosed.
Claims18
A heat exchanger comprising:
- a plurality of flow passages in thermal contact with a cooling flow, the plurality of flow passages including a first end and a second end;
- an inlet manifold at the first end of the plurality of flow passages, the inlet manifold including a plurality of independent splitter passages that communicate airflow to the first end of the plurality of flow passages;

A method of forming a manifold for a heat exchanger comprising:
- creating a plurality of core sections that define a passageway between an inlet and an outlet, wherein each of the plurality of core sections define a common inlet area and outlet area for the passageway;
- defining a mold cavity to receive the core sections that defines an outer shape of the manifold;
- molding the plurality of core sections within the mold cavity to encase the core sections within a casting material;
- and
- removing the core sections from the casting material.
