Claim:
1. A method for minimizing the undesired effect of wind on the operation of a heat exchanger system for cooling liquid having a plurality of finned tube arrays and a plurality of fans for inducing air through the finned tube array, said method comprising the steps of: providing a wind deflector with a rudder, said wind deflector being positioned directly below one of said plurality of fans, wherein the wind deflector is constructed and arranged to divert wind flowing in any approximately horizontal direction below the one of said plurality of fans to instead flow in a direction that is more vertically upward and toward the axis of said one of said plurality of fans as compared to the approximately horizontal direction; setting the height of the wind deflector installed directly below the one of said plurality of fans; collecting readings of an outlet temperature sensor of said heat exchanger, an ambient temperature, a wind sensor, and an inlet air pressure sensor of said heat exchanger; recording readings of the outlet temperature sensor of said heat exchanger, the ambient temperature, the wind sensor and the inlet air pressure sensor of said heat exchanger; comparing readings of the outlet temperature sensor of said heat exchanger, the ambient temperature, the wind sensor and the inlet air pressure sensor of said heat exchanger to previous readings; and carrying out a correction command if said readings have changed, to change the height of said wind deflector, wherein said wind deflector is mounted for rotation about a vertical axis provided directly below said one of said plurality of fans, whereby the rudder can rotate the wind deflector to divert wind flowing in any approximately horizontal direction below the one of said plurality of fans to instead flow in a direction that is more vertically upward and toward the axis of said one of said plurality of fans.
