Abstract
A heat exchanger has: a first manifold assembly having a stack of plates; a second manifold assembly having a stack of plates; and a plurality of tubes extending from the first manifold assembly to the second manifold assembly. The plurality of tubes is a plurality groups of tubes. For each of the groups of the tubes: the tubes of the group have first ends mounted between plates of the first manifold assembly; and the tubes of the group have second ends mounted between plates of the second manifold assembly.
Claims20
A heat exchanger comprising:
- a first manifold assembly comprising a stack of plates;
- a second manifold assembly comprising a stack of plates;
- and
- a plurality of tubes extending from the first manifold assembly to the second manifold assembly,
- wherein:
- the plurality of tubes comprises a plurality groups of tubes;
- and
- for each of the groups of the tubes:
- the tubes of the group have first ends mounted in pockets at junctions between mated plates of the first manifold assembly, the pockets formed by grooves in mating faces of the respective mated plates;
- and
- the tubes of the group have second ends mounted in pockets at junctions between mated plates of the second manifold assembly, the pockets formed by grooves in mating face of the respective mated plates.
A method for manufacturing a heat exchanger, the heat exchanger comprising:
- a first manifold assembly comprising a stack of plates;
- a second manifold assembly comprising a stack of plates;
- and
- a plurality of tubes extending from the first manifold assembly to the second manifold assembly,
- wherein:
- the plurality of tubes comprises a plurality groups of tubes;
- and
- for each of the groups of the tubes:
- the tubes of the group have first ends mounted between plates of the first manifold assembly;
- and
- the tubes of the group have second ends mounted between plates of the second manifold assembly,
- the method comprising:
- stacking the respective plates of the first manifold assembly and the second manifold assembly with the respective first and second ends of the tubes between the associated plates;
- applying compression across the first manifold assembly's plates while applying an electrical current across the first manifold assembly's plates so as to bond the first manifold assembly's plates to each other;
- and
- applying compression across the second manifold assembly's plates while applying an electrical current across the second manifold assembly's plates so as to bond the second manifold assembly's plates to each other.
