Abstract: A heat exchanger system having a fluid inlet member, a fluid outlet member, and a plurality of multi-port heat transfer members. Each of the multi-port heat transfer member extends between the fluid inlet member and the fluid outlet member to define a plurality of fluid paths between the fluid inlet member and the fluid outlet member for carrying a refrigerant or coolant. The plurality of multi-port heat transfer members are spaced apart from each other so as to maximize the product of the total air-side surface area and the heat transfer coefficient of the heat exchanger. If necessary for structural rigidity, at least one reinforcing member fixedly interconnects at least some of the plurality of multi-port heat transfer members in a woven pattern to provide both longitudinal and lateral reinforcement.
