Abstract
A heat exchanger includes a number of fluid carrying tubes disposed in a hot gas flow path. One arrangement of heat exchanger tubes includes a plurality of finned serpentine tubes parallel to one another and connected to an inlet header and an outlet header. The present invention discloses a support for a serpentine tube arrangement and a method of construction for a non-contact heat exchanger.
Claims5
A method of making a heat exchanger box of the type comprising a plurality of individual fluid carrying serpentine tubes each connected to a common inlet header and a common outlet header;
- the serpentine tubes being collectively supported from support beams as a plurality of tube modules in the heat exchanger box by a plurality of tube support sheets including convergent-divergent tube hanger straps;
- the method comprising the steps of:
- prefabricating each serpentine tube from inlet to outlet prior to assembly into a tube module;
- alternately stacking the serpentine tubes with tube hanger straps to form a plurality of tube support sheet sections and a tube module;
- hanging a plurality of tube modules from a plurality of support beams;
- and,
- joining adjacent individual tube support sheet sections aligned in the same plane to form a plurality of tube support sheets.
