Inclined Heat Exchanger with Tapered Ends

摘要

Systems and methods are disclosed that include providing a heating, ventilation, and/or air conditioning (HVAC) system with a tapered end heat exchanger (TEHE) having a first tapered end disposed at a lower end of the TEHE with respect to an incoming airflow and on the downstream face of the TEHE and having a second tapered end disposed at an upper end of the TEHE with respect to an incoming airflow and on the upstream face of the TEHE. A drain pan having louvers is disposed about the lower end of the TEHE and configured to restrict airflow through narrow portions of the first tapered end of the TEHE. A baffle is disposed about the upper end of the TEHE and configured to restrict airflow through narrow portions of the second tapered end of the TEHE.

主权项

1. A heat exchanger, comprising:
an upstream face and a downstream face; a plurality of tubes arranged in a plurality of rows; a plurality of fins disposed along the tubes; and at least one tapered end disposed on the heat exchanger, wherein the tapered end is closer to being perpendicular to a primary incoming airflow direction than at least one of the upstream face and the downstream face of the heat exchanger.
