Abstract

A heat exchanger comprising a plurality of parallel fins and at least one tube passing through the tubes of 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 curved substantially orthogonally with respect to the planar surface of each fin, and each air deflecting member is configured to direct air passing through the heat exchanger to increase turbulence of the air and impinge the air against adjacent parallel fins. fins, and equalizes the airflow through the heat exchanger and reduces uneven distribution of airflow through the heat exchanger.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Utility Model Application No. 15 / 689,597 filed on August 29, 2017, and also claims the rights of U.S. Provisional Patent Application No. 62 / 381,802 filed on August 31, 2016. The entire disclosure of the aforementioned application is incorporated herein by reference. Technical field [0003] The present disclosure relates to a heat exchanger having a fin reinforcement device, which is used in a configuration in which the airflow passing through the heat exchanger exhibits a low Reynolds number. Background technique [0004] This section provides background information related to the present disclosure, which is not necessarily prior art. [0005] Such as figure 1 with figure 2 As shown in, the conventional heat exchanger 10 of the plate-fin type generally includes a plurality of parallel tubes 12 having a plurality of vertical fins 14. The plurality of vertical fins 14 are thermally...
