Abstract
A water chiller includes a cooling tank and a cooling device positioned at an upper portion of the cooling tank. The cooling device includes a cooling probe positioned within the cooling tank at an upper region thereof and being operable to cool the water at the upper region of the cooling tank. The cooled water increases in density and descends toward the bottom or lower region of the cooling tank, while warmer water positioned in the lower region rises upwards toward the cooling probe, where it is cooled by the cooling probe. The water cooler thus continually cools and mixes the water within the cooling tank to maintain the water at a cool temperature. The cool water at the lower region of the tank is discharged from the cooling tank at an outlet positioned at or near the bottom of the cooling tank.
