Abstract
A furnace has a primary heat exchanger tube, a secondary heat exchanger comprising a plurality of secondary heat exchanger tubes, a hot header configured to provide a fluid flow path between an output of the primary heat exchanger tube to an input of the secondary heat exchanger, and a perforated fluid flow plate disposed at least partially within the hot header.
Claims20
A furnace, comprising:
- a primary heat exchanger tube;
- a secondary heat exchanger comprising a plurality of secondary heat exchanger tubes;
- a hot header configured to provide a fluid flow path between an output of the primary heat exchanger tube to an input of the secondary heat exchanger;
- and
- a perforated fluid flow plate disposed at least partially within the hot header wherein the perforated fluid flow plate comprises an interior wall comprising:
- a first portion distanced from the secondary heat exchanger tubes, the first portion comprising a plurality of perforations that are misaligned relative to the secondary heat exchanger tubes;
- and
- a second portion abutting the secondary heat exchanger.
