Abstract
A heat exchanger including a plurality of parallel fins, and at least one tube passing through the parallel fins, wherein the tube carries a fluid that exchanges heat with air passing through the heat exchanger. The parallel fins each include a plurality of air deflecting members formed therein. Each air deflecting member is bent substantially orthogonally relative to a planar surface of each fin, and each air deflecting member is configured to direct the air passing through the heat exchanger to increase turbulence of the air, and to impinge the air against adjacent parallel fins, and to balance air flow across the heat exchanger and decrease maldistribution of the air flow through the heat exchanger.
Claims13
A heat exchanger, comprising:
- a plurality of parallel fins;
- and
- at least one tube of a serpentine configuration having a plurality of passes in an airflow path and passing through the parallel fins, the tube carrying a fluid that exchanges heat with air passing through the heat exchanger in the airflow path,
- wherein the parallel fins each include a plurality of air deflecting members that are tabs stamped therefrom such that each air deflecting member of each individual fin of the plurality of parallel fins is bent in the same direction relative to a planar surface of each fin and an aperture is formed in the fin at a location where a material of a respective parallel fin that forms the air deflecting member was previously located, and each air deflecting member configured to direct the air passing through the heat exchanger;
- and
- the air deflecting members of a respective fin are staggered relative to the air deflecting members of immediately adjacent parallel fins that sandwich the respective fin.
