Abstract:

A plastic container which confines a freezable liquid is provided with a multitude of parallel channels which permit passage of air through the container. The container is mountable upon the protective enclosure of a multi-bladed air-moving fan in a manner such that air driven by the fan passes through the channels and is thereby cooled. The container is of a small enough size to permit its storage within a residential-type freezer to freeze the liquid prior to mounting of the container upon the fan. 2.
