Centrifugal cooling device
 Improvements in a centrifugal cooling tower which include a housing having a water tank, a water valve, an over-flow pipe and an outlet at its lower portion. The housing has louvers on its perimeter and upper portion with louvers defining a number of long slits for air to be readily drawn in. A screen structure near the upper inside of the housing collects the upwardly rising water vapor to form condensated which falls down into the tank to be used for re-circulated. Fixed beams and a motor are mounted on a fixed post in the inside center of the body frame. Supports are fixed to the post respectively by a deflection screen member and a perforated drum of the rotating cylinder supported in position by a shaft. The perforated drum has a spiral blade fan for drawing in a large amount of outside air to perform heat exchange with droplets of water.
