HEAT EXCHANGER WITH ENHANCED AIRFLOW

摘要

Systems, apparatuses, and methods described herein are directed to a heat exchange tube structure and an arrangement of heat exchange tubes that enhance or help promote fluid flow through a heat exchanger. Bend portions of heat exchange tubes may be structured and configured to allow for gaps so that fluid may pass an assembly of the heat exchange tubes. The heat exchange tubes may be arranged to expose the air gaps at the bend portions of the heat exchange tubes to promote fluid flow.

主权项

1. A heat exchange tube, comprising:
a first leg; a second leg; a bend portion connected to the first leg and the second leg, the bend portion disposed between the first leg and the second leg, the first and second legs are generally parallel to each other due to the connection with the bend portion, the bend portion is disposed at one end of the heat exchange tube, and the first and second legs have free ends disposed at an end opposite the bend portion; and a flow passage through the first leg, the bend portion, and the second leg, the flow passage suitable to pass a fluid therethrough to establish a heat exchange relationship with a fluid passing over outside the heat exchange tube, the bend portion includes a first bend that connects the first leg to the bend portion and a second bend that connects the bend portion to the second leg, the first and second bends create a fluid flow opening proximate the bend portion suitable to promote fluid flow therethrough and to pass outside the heat exchange tube.
