DUAL DUTY MICROCHANNEL HEAT EXCHANGER

摘要

A heat exchanger includes a first tube bank having at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship. A second tube bank includes at least a first group of flattened tube segments and a second group of flattened tube segments extending longitudinally in spaced parallel relationship. The second tube bank is disposed behind the first tube bank with a leading edge of the second tube bank spaced from a trailing edge of the first tube bank. The first group of flattened tube segments is configured to receive a first fluid. The second group of flattened tube segments is configured to receive a second fluid. A fan provides an airflow across the first tube bunk and the second tube bank sequentially.

1. A heat exchanger comprising:
a first tube bank including at least a first and a second flattened tube segments extending longitudinally in a spaced, parallel relationship; a second tube bank including at least a first group of flattened tube segments and a second group of flattened tube segments extending longitudinally in a spaced, parallel relationship, the second tube bank disposed behind the first tube bank with a leading edge of the second tube bank spaced from a trailing edge of the first tube bank, the first group of flattened tube segments is fluidly coupled to the first tube bank and is configured to receive a first fluid and the second group of flattened tube segments is configured to receive a second fluid; and a fan configured to provide an airflow across the first tube bank and the second tube bank sequentially.
