A heat exchanger comprising:
- first and second integral fin passages, each integral fin passage having integrally formed plates and extended surfaces;
- and
- a fin located between and bonded to outer surfaces of the first and second integral fin passages.
A core of a plate-fin heat exchanger, the core comprising:
- a plurality of integral fin passages, each integral fin passage having first and second plates and a plurality of extended surfaces extending between the first and second plates, the plates and the extended surfaces being integral, the plates and extended surfaces defining first passageways;
- and
- a plurality of fins, each fin being located between and bonded to plates of adjacent integral fin passages, the plates and the fins defining second passageways.
A method of constructing a heat exchanger, the method comprising:
- providing a plurality of integral fin passages, each integral fin passage having been extruded to form plates and extended surfaces;
- and
- locating fins between outer surfaces of adjacent integral fin passages;
- and
- bonding the fins to the outer surfaces of the integral fin passages.
