Patent ID: 8739855

Claim:
A cooling system comprising: a first flue and a second flue cooperatively defining an air passageway; a fan disposed in the air passageway to generate an airflow through the first and second flue; and an evaporator in communication with at least one of the first flue and the second flue for cooling the airflow, the evaporator comprising an inlet header configured to receive a cooling fluid; an outlet header configured to discharge the cooling fluid; and a plurality of microchannel tubes in fluid communication with and extending between the inlet header and the outlet header, the microchannel tubes defining a first side of the heat exchanger between the inlet header and the outlet header and an opposed second side of the heat exchanger between the inlet header and the outlet header, wherein the first and second flue define a bend in the air passageway, and further wherein the evaporator is positioned at the bend such that the airflow passes from the first side to the second side in a first direction and then passes from the second side to the first side in a second direction different from the first direction.
