Abstract
The present invention is directed to a cooling tower that has a cooling tower structure having fill material supported by the cooling tower structure and configured to receive heated process fluid and a motor mounted to the cooling tower structure. The motor has a casing and a rotatable shaft and is sealed to prevent fluids, moisture, foreign particles and contaminants from entering the casing. A fan is connected to the rotatable shaft of the motor. Rotation of the rotatable shaft rotates the fan thereby inducing an upward moving mass flow of cool air through the fill material. A basin is attached to the cooling tower structure for collecting cooled fluid. A fluid distribution system distributes the cooled fluid in the basin. The fluid distribution system has a pumping device to pump cooled fluid from the basin, fluid piping to receive the pumped cooled fluid and fluid spray devices fluidly connected to the fluid piping for spraying fluid on the casing of the motor so as to transfer heat of the casing to the fluid.
