Abstract
An apparatus and method of forming a heat exchanger includes forming a monolithic core body having a first set of flow passages and a core coefficient of thermal expansion, and additively manufacturing onto the monolithic core a first manifold defining a first fluid inlet for the first set of flow passages.
Claims19
A method of forming a heat exchanger, the method comprising:
- forming a monolithic core comprising a first set of flow passages and having a core coefficient of thermal expansion (CTE);
- and
- additively manufacturing onto the monolithic core a first manifold to define an integral, unitary body having the monolithic core and the first manifold, with the first manifold defining a first fluid inlet in fluid communication with the first set of flow passages, wherein at least a portion of the first manifold has a first CTE less than the core CTE.
A method of forming a heat exchanger, the method comprising:
- forming a monolithic core having a first set of flow passages from a core material having a core coefficient of thermal expansion (CTE);
- and
- additively manufacturing a first manifold from a first material different than the core material onto the monolithic core to define an integral, unitary body having the monolithic core and the first manifold, with the first manifold in fluid communication with the first set of flow passages and having a first CTE lower than the core CTE, wherein the first material comprises a nickel alloy.
A heat exchanger, comprising:
- an integral, unitary body comprising a monolithic core body and a first manifold;
- with the monolithic core body comprising a first set of flow passages and having a core coefficient of thermal expansion (CTE), and with the first manifold unitarily formed with the monolithic core body and in fluid communication with and defining a first fluid inlet for the first set of flow passages;
- wherein at least a portion of the first manifold has a first CTE that is different from the core CTE.
