Abstract
Methods and systems are provided for heat exchangers including a first outer plate, a second outer plate, and an intermediate plate. The intermediate plate is positioned between the outer plates. Fluid flow passages are formed between the intermediate plate and each of the outer plates.
Claims20
A heat exchanger, comprising:
- an intermediate plate positioned between a first outer plate and a second outer plate;
- first fluid flow passages formed between the first outer plate and a first side of the intermediate plate;
- second fluid flow passages formed between the second outer plate and a second side of the intermediate plate;
- a first fluid manifold formed between the first outer plate and the first side of the intermediate plate, and the first fluid manifold positioned at a first end of the first fluid flow passages;
- a second fluid manifold formed between the second outer plate and the second side of the intermediate plate, and the second fluid manifold positioned at a second end of the second fluid flow passages;
- and
- the first fluid manifold and the second fluid manifold positioned on a first end of the heat exchanger, the first fluid manifold and the second fluid manifold located entirely inside of a plate structure defined by the first outer plate, the second outer plate, and the intermediate plate,
- wherein a width of the first fluid flow passages and a width of the second fluid flow passages varies along a length of the heat exchanger in a first region of the heat exchanger, and
- wherein the width of the first fluid flow passages and the width of the second fluid flow passages is substantially constant along the length of the heat exchanger in a second region of the heat exchanger.
