Abstract

A heat exchanger for use with a heat pump water heater, the heat exchanger including a first header, a second header, multiple heat exchange tubes extending between the first header and the second header, an inlet pipe connected to the first header, a discharge pipe connected to at least one of the first header and the second header, and a bulkhead positioned in the first header. Each of the heat exchange tubes is curved and includes a flat surface. The bulkhead is positioned such that a circuitous flow path is formed between the first header and the second header. The flow path is configured so that refrigerant flows from the first header to the second header through a first set of heat exchange tubes and then from the second header to the first header through a second set of heat exchange tubes.
