Apparatus and method for providing an ice cooled fan screen. The invention is composed of a support frame into the top of which is designed a chamber suitable for holding ice. The chamber has a floor which slopes towards one side of the screen so that melting ice water will collect there. Connected to the floor at the lower end of the chamber is a hollow copper tube which receives the ice water and directs it through a series of "S" turns downward to the base of the support frame. The end of the copper tube has a positive shut off valve so that the ice water may be retained within the tube as long as desired. The base of the support is further designed to provide for a melted ice chamber. Located within this chamber is a removable refreezing tray which is connected to the positive shut off valve by a draining means. As described, the ice cooled fan screen is suitable for placement in front of any common fan to provide for a unique, inexpensive means to substantially cool living, working and playing areas. Another preferred embodiment of the invention is described by placement of an air moving fan within the support frame directly behind the hollow copper tubing. In this configuration, the device is a fully portable, inexpensive cooling means.
