Abstract: A fan air cooler for attachment to a conventional electric fan consists of a grid of spaced strips filled with a frozen fluid material. The strips may have spaced fluid sacks which may resemble ice cubes. The connecting strips between the fluid filled sacks may comprise plastic strips, fluid filled tubes or helical fluid filled tubes. A top marginal portion of the grid is provided with grommets for receipt over hooks which are secured to a top edge of the fan housing. The hooks may be attached to the fan housing magnetically, adhesively or by VELCRO. In addition to cooling air by passing the air between the frozen fluid filled strips, the fan air cooler also cools the air by virtue of thermodynamic expansion of the air through spaced air passage apertures.
