Claim:
1. A heat exchanger to transfer heat between a refrigerant and air, comprising: a refrigerant flow path extending between a first refrigerant port and a second refrigerant port; a first section, a second section, and a third section of the heat exchanger arranged sequentially along the refrigerant flow path, the first section arranged between the first refrigerant port and the second section, the third section arranged between the second refrigerant port and the second section; first and second parallel arranged air flow paths extending through the heat exchanger, the first airflow path extending sequentially through the first section and the third section and bypassing the second section, the second airflow path extending through the second section and bypassing the first section and the third section, wherein heat transfer between the refrigerant and air is substantially inhibited in the first section of the heat exchanger; and a plurality of extended surface features arranged along the first and second air flow paths to promote heat transfer between the air and the refrigerant, said plurality of extended surface features being uniformly distributed throughout the second and third sections, wherein the first section is absent of said extended surface features, wherein the first refrigerant port is positioned a first distance from the second section and the second refrigerant port is positioned a second distance from the second section, and wherein the first distance is substantially the same as the second distance.
